| ○ | ○ | Article | Risk factors of trauma-induced thrombotic microangiopathy-like syndrome: A retrospective analysis | Patients with trauma may develop thrombocytopenia. We encountered cases wherein patients experienced symptoms resembling thrombotic microangiopathies (TMAs) following severe trauma. As the condition of these patients did not meet the diagnostic criteria of thrombotic thrombocytopenic purpura and there was no mention of trauma among the several causes of TMAs, it was termed as "trauma-induced thrombotic microangiopathy-like syndrome" (t-TMAS). In this study, we aimed to analyze the risk factors that may affect the incidence of t-TMAS in patients with severe trauma. This retrospective study was conducted in the trauma intensive care unit at the Kyungpook National University Hospital between January 2018 and December 2019. The medical records of 1164 of the 1392 enrolled participants were analyzed. To assess the risk factors of t-TMAS, we analyzed age, sex, mechanism of trauma, abbreviated injury scale (AIS) score, injury severity score (ISS), hematological examination, and red blood cell volume transfused in 24 hours. Among the 1164 patients, 20 (1.7%) were diagnosed with t-TMAS. The univariate analysis revealed higher age, ISS, and myoglobin, lactate, creatine kinase-myocardial band (on admission), creatine phosphokinase, lactate dehydrogenase (LDH), and lactate (day 2) levels in the t-TMAS group than in the non-t-TMAS group. The red blood cell volume transfused in 24 hours was higher in the t-TMAS group than in the non-t-TMAS group. t-TMAS was more common in patients with injuries in the chest, abdomen, and pelvis (AIS score >= 3) than in those with head injuries (AIS score >= 3) alone. The higher the sum of AIS scores of the chest, abdomen, and pelvis injuries, the higher the incidence of t-TMAS. Multivariate analysis revealed age, ISS, and LDH level (day 2) to be independent predictors of t-TMAS. Trauma surgeons should consider the possibility of t-TMAS if thrombocytopenia persists without any evidence of bleeding, particularly among older patients with multiple severe torso injuries who have high LDH levels on day 2. Early diagnosis and treatment of t-TMAS could improve patients' prognosis. | Lim, Kyoung Hoon; Park, Jinyoung; Cho, Sung Hoon | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Surg, Daegu, South Korea | PARK, JUN-YOUNG/P-5981-2015 | 25630643100; 57190865032; 57755400700 | drlimkh@knu.ac.kr;ttangguri@hanmail.net;drlimkh@naver.com; | MEDICINE | MEDICINE | 0025-7974 | 1536-5964 | 101 | 29 | SCIE | MEDICINE, GENERAL & INTERNAL | 2022 | 1.6 | 70.1 | 0.32 | 2025-06-25 | 3 | 2 | risk factor; thrombocytopenia; thrombotic microangiopathy; trauma | THROMBOCYTOPENIC PURPURA; PATHOPHYSIOLOGY; INJURY | risk factor; thrombocytopenia; thrombotic microangiopathy; trauma | Humans; Injury Severity Score; Lactates; Multiple Trauma; Retrospective Studies; Risk Factors; Thrombotic Microangiopathies; creatine kinase; creatine kinase MB; lactate dehydrogenase; lactic acid; methylprednisolone; myoglobin; rituximab; von Willebrand factor cleaving proteinase; lactic acid; abdominal injury; acute kidney failure; aged; Article; blood analysis; chronic kidney failure; controlled study; creatine kinase blood level; digital necrosis; disease severity; emergency health service; enzyme activity; enzyme blood level; erythrocyte transfusion; erythrocyte volume; female; fever; head injury; hemodialysis; hospital admission; hospital discharge; hospitalization; human; incidence; injury; injury scale; intensive care unit; laboratory test; lactate blood level; lactate dehydrogenase blood level; major clinical study; male; medical record review; mental disease; necrosis; pelvis injury; plasma exchange; platelet count; protein blood level; remission; renal replacement therapy; retrospective study; risk factor; thorax injury; thrombotic microangiopathy; multiple trauma; risk factor; thrombotic thrombocytopenic purpura | English | 2022 | 2022-07-22 | 10.1097/md.0000000000029315 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Serum anti-Mullerian hormone recovery after ovarian cystectomy for endometriosis: A retrospective study among Korean women | Serum anti-Mullerian hormone (sAMH) is a useful marker of ovarian reserve. In many patients, the sAMH levels gradually recover after falling to the lowest level after surgery (nadir phenomenon). This study aimed to analyze the factors related to sAMH recovery from the nadir after an ovarian cystectomy for endometriosis among Korean women. A total of 159 patients with ovarian endometriosis were included in the study. The sAMH levels were measured before surgery and at least twice within 12 months after the surgery. The patients were divided into two groups: those with recovery (nadir group) and those without recovery (reduction group). Postoperative recovery of the sAMH levels from the nadir was not related to the stage and bilaterality of the lesion, surgical methods, such as robot-assisted or laparoscopic surgery, or surgical time. In the nadir group, the level of preoperative cancer antigen 125 was significantly higher, and it decreased significantly after the surgery than in the reduction group (P = .02 and P = .02). Additionally, the postoperative C-reactive protein (CRP) level was significantly higher in the nadir group, and it increased significantly after the surgery than in the reduction group (P = .03 and P = .04). The increasing degree of perioperative CRP level showed a cutoff value on the receiver operating characteristic curve (0.735 mg/dL, area under curve = 0.604; P = .04). Increased serum CRP levels after surgery are significantly related to the recovery of sAMH levels from the nadir. Therefore, postoperative serum CRP level could be used as a marker to predict the sAMH nadir after surgery. | Lee, Juhun; Hong, Dae Gy | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Obstet & Gynecol, Daegu, South Korea | 57360628800; 26656670100 | dghong@knu.ac.kr; | MEDICINE | MEDICINE | 0025-7974 | 1536-5964 | 101 | 40 | SCIE | MEDICINE, GENERAL & INTERNAL | 2022 | 1.6 | 70.1 | 0 | 2025-06-25 | 0 | 0 | anti-Mullerian hormone; inflammation; ovarian cystectomy; ovarian endometriosis; ovarian reserve | RESERVE; IMPACT | anti-Müllerian hormone; inflammation; ovarian cystectomy; ovarian endometriosis; ovarian reserve | Anti-Mullerian Hormone; C-Reactive Protein; CA-125 Antigen; Cystectomy; Endometriosis; Female; Humans; Laparoscopy; Ovarian Reserve; Republic of Korea; Retrospective Studies; C reactive protein; CA 125 antigen; dienogest; hemostatic agent; Muellerian inhibiting factor; oral contraceptive agent; C reactive protein; CA 125 antigen; Muellerian inhibiting factor; adult; area under the curve; Article; controlled study; female; hormone blood level; human; Korean (people); laparoscopic surgery; major clinical study; operation duration; ovarian cystectomy; ovarian endometriosis; postoperative period; preoperative period; retrospective study; robot-assisted cystectomy; cystectomy; endometriosis; laparoscopy; ovarian reserve; South Korea | English | 2022 | 2022-10-07 | 10.1097/md.0000000000030977 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Serum neurofilament light chain levels are correlated with the infarct volume in patients with acute ischemic stroke | Neurofilament light chains (NfLs) are promising biomarkers of neuroaxonal damage in stroke patients. We investigated the correlations between NfL levels and infarct volume, initial stroke severity, and functional outcomes at discharge in patients with acute ischemic stroke. We prospectively included 15 patients with first-ever acute ischemic stroke and 8 age- and sex-matched healthy controls without other neurological disorders. Serum NfL levels were measured using the single-molecule array (Simoa) technique twice within 24 hours of admission (NfL(1D)) and on the seventh hospital day (NfL(7D)) in patients with stroke and once in healthy controls. We assessed the infarct volume on diffusion-weighted magnetic resonance imaging using the free software ITK-SNAP. Serum NfL(1D) levels in stroke patients were significantly higher (28.4 pg/mL; interquartile range [IQR], 43.0) than in healthy controls (14.5 pg/mL; IQR, 3.2; P = .005). Temporal pattern analyses demonstrated that NfL(7D) levels were increased (114.0 pg/mL; IQR, 109.6) compared to NfL(1D) levels in all stroke patients (P = .001). There was a strong correlation between NfL(7D) levels and infarct volume (R = 0.67, P = .007). The difference between NfL(1D) and NfL(7D) (NfL(diff) levels) was strongly correlated with the infarct volume (R = 0.63; P = .013). However, there was no statistically significant correlation between NfL levels and the initial stroke severity or functional outcomes at discharge. NfL levels in the subacute stage of stroke and the NfL difference between admission and 7th day of hospital were correlated with infarct volume in patients with acute ischemic stroke. | Ahn, June Woo; Hwang, Jaechun; Lee, Myunghoon; Kim, Jae Hyoung; Cho, Hee-Jin; Lee, Ho-Won; Eun, Mi-Yeon | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Neurol, Daegu, South Korea; D&P Biotech Inc, Res Ctr, Daegu, South Korea; Kyungpook Natl Univ, Brain Sci & Engn Inst, Daegu, South Korea | ; Eun, Mi-Yeon/AAV-2877-2021 | 57216162940; 54980345300; 57916770400; 57916014000; 55937716400; 35337240700; 36463396500 | neuromd@knu.ac.kr; | MEDICINE | MEDICINE | 0025-7974 | 1536-5964 | 101 | 39 | SCIE | MEDICINE, GENERAL & INTERNAL | 2022 | 1.6 | 70.1 | 1.91 | 2025-06-25 | 11 | 12 | Asian; infarct volume; neurofilament light chain; stroke | Asian; infarct volume; neurofilament light chain; stroke | Biomarkers; Humans; Infarction; Intermediate Filaments; Ischemic Stroke; Neurofilament Proteins; Stroke; biological marker; neurofilament light chain; neurofilament protein; unclassified drug; biological marker; neurofilament protein; abnormal value; acute ischemic stroke; age; aged; Article; clinical article; clinical outcome; comparative study; controlled study; correlation coefficient; diffusion weighted imaging; disease severity; female; functional status; hospital admission; hospital discharge; human; infarct volume; length of stay; male; neuroimaging; observational study; prospective study; protein blood level; Rankin scale; sex; stroke patient; brain ischemia; cerebrovascular accident; diagnostic imaging; infarction; intermediate filament | English | 2022 | 2022-09-30 | 10.1097/md.0000000000030849 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Sudden arrhythmia in the prone position during spinal surgery: A case report | Rationale: The prone position is the most commonly required position during spinal surgery. Decreasing lumbar lordosis is necessary to facilitate the accessibility of the surgical field. And this can affect the hemodynamic circulation of the patients. The Jackson spine table is one of the most preferred methods, known to have minimal effects on cardiac function. Patient concerns: We report a case of sudden arrhythmia that developed during the prone position using a Jackson spine table. It occurred 30 minutes after the positional change. Diagnoses: Arrhythmia showed bizarre P and QRS waves. Ectopic P, bundle branch block, or both was suspected. Interventions: Because it was difficult to define the exact type or cause of this sudden arrhythmia and considering that other vital signs remained stable, we decided to keep close observation during the operation rather than applying uncertain antiarrhythmic medication. Outcomes: Arrhythmia spontaneously developed and subsided repeatedly. And it recovered to normal sinus rhythm immediately after the positional change to the supine position. Therefore, increased intrathoracic pressure caused by the prone position was highly suspected to be the cause of this event. Lessons: Although the Jackson spine table is known to have the least effect on cardiac function, the patient experienced arrhythmia in our case. Hence, to achieve better clinical outcomes, an understanding of physiological alterations and possible complications caused by the prone position is necessary for earlier diagnosis and management. | Kim, Ji Hyun; Kim, Sora; Yu, Taeyoung; Yang, Woo Seok; Hong, Seong Wook | Kyungpook Natl Univ Hosp, Dept Anesthesiol & Pain Med, 130 Dongdeok Ro, Daegu 41944, South Korea | Kim, Ji Hyun/W-1332-2019 | 58607576700; 57847230800; 58594325600; 57224069580; 57216387309 | etelily@naver.com; | MEDICINE | MEDICINE | 0025-7974 | 1536-5964 | 101 | 33 | SCIE | MEDICINE, GENERAL & INTERNAL | 2022 | 1.6 | 70.1 | 0.48 | 2025-06-25 | 3 | 3 | arrhythmia; pressure; prone position; spinal stenosis | CARDIAC-FUNCTION | Arrhythmia; Pressure; Prone position; Spinal stenosis | Arrhythmias, Cardiac; Humans; Lumbar Vertebrae; Neurosurgical Procedures; Patient Positioning; Prone Position; Spine; adverse event; case report; heart arrhythmia; human; lumbar vertebra; neurosurgery; patient positioning; physiology; prone position; spine | English | 2022 | 2022-08-19 | 10.1097/md.0000000000030137 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Two cases of extramedullary plasmacytoma of the small intestine presenting with ileus: A case report | Background: Extramedullary (extraosseous) plasmacytoma (EMP) of the small intestine is a rare plasma cell neoplasm (PCN) that presents with abdominal pain, nausea, vomiting, etc. We describe 2 cases of EMP of the small intestine that presented with ileus. Methods: A 78-year-old woman and 68-year-old man visited our clinic with complaints of abdominal discomfort and obstruction. Abdominal computed tomography (CT) revealed a thickened lesion with multiple enlarged mesenteric lymph nodes (LNs) in the ileum and duodenum. The female patient underwent segmental resection in the ileum. The male patient underwent Whipple's operation in the duodenum. Results: Histopathological examination and immunohistochemical staining of resected specimens from the 2 patients confirmed a PCN. In the surgical specimens of 2 cases, immunoglobulin heavy-chain rearrangement was confirmed by polymerase chain reaction amplification, but no Epstein-Barr virus (EBV)-infected cells were found by EBV-in situ hybridization. Bone marrow aspirate and trephine biopsies were negative for the type of PCN. Bone marrow cytogenetics and fluorescence in situ hybridization revealed no abnormalities. Serum beta 2-microglobulin levels were within normal limits. Additionally, none of the patients showed an M-spike in serum or urine protein electrophoresis. Therefore, the patients were diagnosed with a solitary EMP of the small intestine. The female patient refused treatment. At follow-up 3 months postoperatively, her disease progressed and she newly developed multiple LNs and nodular lesions in the right pelvic side wall. She was treated with dexamethasone. The male patient experienced back pain 25 days after Whipple's operation. Spine series magnetic resonance imaging revealed an intermediate signal intensity mass in the posterior epidural space from T8/9 to T10. The mass was removed, and the same histologic features were identified as duodenal masses. He was treated with dexamethasone and radiotherapy. Conclusions: EMPs of the small intestine are easy to overlook because they rarely occur in the small intestine. Although surgery is not required for diagnosis, surgical resection can be a good option for EMPs of the small intestine, instead of local radiation therapy. However, close follow-up is required due to the possibility of relapse or progression to plasma cell myeloma. | Park, Ki Bum; Kwon, Hyung Jun; Jeong, Ji Yun; Baek, Dong Won; Cho, Seung Hyun; Seo, An Na | Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Surg, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Pathol, 807 Hogukno, Daegu 41404, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Sch Med, Dept Radiol, Daegu, South Korea | 57220965452; 57199757347; 57205472984; 57191874272; 55686242700; 55804153700 | san_0729@naver.com; | MEDICINE | MEDICINE | 0025-7974 | 1536-5964 | 101 | 40 | SCIE | MEDICINE, GENERAL & INTERNAL | 2022 | 1.6 | 70.1 | 0.16 | 2025-06-25 | 1 | 1 | extramedullary plasmacytoma; ileus; multiple myeloma; small intestine | MULTIPLE-MYELOMA; MANAGEMENT; DIAGNOSIS | extramedullary plasmacytoma; ileus; multiple myeloma; small intestine | Aged; Dexamethasone; Female; Humans; Ileus; Immunoglobulins; In Situ Hybridization, Fluorescence; Intestinal Obstruction; Intestine, Small; Male; Multiple Myeloma; Plasmacytoma; Pregnenolone Carbonitrile; dexamethasone; immunoglobulin heavy chain; 16alpha cyanopregnenolone; dexamethasone; immunoglobulin; abdominal discomfort; aged; Article; backache; bone marrow biopsy; cancer radiotherapy; case report; clinical article; cytogenetics; female; fluorescence in situ hybridization; follow up; histopathology; human; human tissue; ileus; immunohistochemistry; male; nuclear magnetic resonance imaging; pancreaticoduodenectomy; plasmacytoma; polymerase chain reaction; segmentectomy; small intestine tumor; treatment refusal; x-ray computed tomography; complication; intestine obstruction; multiple myeloma; pathology; plasmacytoma; small intestine | English | 2022 | 2022-10-07 | 10.1097/md.0000000000030842 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Two cases of neurilemmoma in the nasal vestibule A case report and literature review | Rationale: Neurilemmoma is a benign tumor derived from the Schwann cells of the nerve sheath. The highest incidence of neurilemmoma occurs in the head and neck region; however, the nose and paranasal sinuses are rarely involved. Less than 4% of these tumors involve the nasal cavity and paranasal sinuses. To date, only six cases of nasal vestibule neurilemmoma have been reported. Patient concerns: Two patients (a 32-year-old man and a 42-year-old woman) visited our clinic with complaint of a lump in the left nasal vestibule. Diagnosis: Histopathological examination and immunohistochemical staining confirmed a neurilemmoma. Interventions: The mass was completely removed via an intranasal approach. Outcomes and Lessons: Neurilemmoma is easy to overlook because it occurs rarely in the nasal vestibule, but neurilemmoma needs to be considered as a differential diagnosis. | Heo, Sung Jae; Kim, A.

| ○ | ○ | Article | What makes acute cholecystitis recur after removing the percutaneous cholecystostomy tube? | Percutaneous transhepatic gallbladder drainage (PTGBD) is an alternative treatment option for acute cholecystitis. However, the disease may recur after PTGBD catheter removal. This study aimed to evaluate the role of endoscopic sphincterotomy and other risk factors in reducing the recurrence of cholecystitis. We retrospectively analyzed data from 1088 patients who underwent PTGBD for cholecystitis at Kyungpook National University Hospital, Republic of Korea, between January 2011 and April 2018. A total of 115 patients were enrolled in the study. The recurrence rate of cholecystitis was 17.4% (n = 20) during a median follow-up period of 1159 (range, 369-2774) days. Endoscopic biliary sphincterotomy did not significantly affect the recurrence rate of cholecystitis (P = .561). In multivariable analysis, cystic duct stones (P = .013) and PTGBD catheter migration before the prescheduled removal time (P = .002) were identified as independent risk factors for cholecystitis recurrence after PTGBD. To reduce post-PTGBD recurrence in cholecystitis, caution must be exercised to avoid inadvertent dislodging of the PTGBD catheter. In cases of cholecystitis with cystic duct stones, cholecystectomy should be considered only after careful assessment of postoperative risks. Instead, transluminal endoscopic gallbladder drainage could represent a promising option for the prevention of recurrent cholecystitis. | Heo, Jun; Jung, Min Kyu; Cho, Chang Min; Lee, Sang Yub; Ryeom, Hun Kyu; Chun, Jae Min; Han, Young Seok; Kwon, Hyung Jun | Kyungpook Natl Univ, Sch Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Surg, Daegu, South Korea | Kim, Young/J-5414-2012; Lee, Joo/C-3851-2013 | 36448170600; 56783168100; 57158287600; 56016177400; 6505864513; 24773178000; 7404096216; 57199757347; 58180510500 | minky1973@knu.ac.kr; | MEDICINE | MEDICINE | 0025-7974 | 1536-5964 | 101 | 5 | SCIE | MEDICINE, GENERAL & INTERNAL | 2022 | 1.6 | 70.1 | 0.96 | 2025-06-25 | 5 | 6 | acute; cholecystitis; drainage; endoscopic retrograde cholangiopancreatography; recurrence; sphincterotomy | HIGH-RISK PATIENTS; GALLBLADDER DRAINAGE; STENT | acute; cholecystitis; drainage; endoscopic retrograde cholangiopancreatography; recurrence; sphincterotomy | Catheters; Cholecystitis, Acute; Cholecystolithiasis; Cholecystostomy; Device Removal; Drainage; Gallbladder; Humans; Recurrence; Retrospective Studies; Sphincterotomy, Endoscopic; Treatment Outcome; acute cholecystitis; aged; Article; catheter migration; catheter removal; cholecystectomy; cholecystostomy; controlled study; cystic duct; data analysis software; device removal; endoscopic retrograde cholangiopancreatography; endoscopic sphincterotomy; female; follow up; gallbladder drainage; human; major clinical study; male; medical device complication; percutaneous transhepatic drainage; recurrence risk; recurrent disease; retrospective study; risk assessment; risk factor; South Korea; university hospital; acute cholecystitis; catheter; cholelithiasis; endoscopic sphincterotomy; gallbladder; recurrent disease; treatment outcome | English | 2022 | 2022-02-04 | 10.1097/md.0000000000028767 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Epidemiological Characteristics of Paediatric Eye Injuries in a Large Metropolitan City in South Korea: A Multicentre, Prospective Study | Purpose : The aim of this study was to identify the epidemiological characteristics of paediatric eye injury in a large metropolitan city based on age group and sex. Methods : This prospective, multicentre, observational study used data extracted from the eye injury registry for tertiary teaching hospitals in Daegu, South Korea, between August 2016 and July 2018. Children aged < 16 years were classified as infants, pre-schoolers, school children, and adolescents based on their age group. Results : This study included 502 patients; most eye injuries occurred among boys (n = 349, 69.5%) and school children (n = 168, 33.5%). Unstructured play (n = 268, 53.4%) was the most common cause of eye injury, followed by sports (n = 69, 13.7%) and home activities (n = 52, 10.4%). Among adolescent boys, eye injuries were mostly caused by sports activities (n = 49, 37.7%), including soccer and basketball. Only 1 out of 69 children wore protective eyewear during sports activities. Eye injuries occurred most often in school (n = 63, 41.2%) during adolescence and at home (n = 270, 53.8%) in most other age groups. Conclusion : Eye injuries were more common in boys. Boys and girls had relatively higher proportion of eye injuries during sports and home activities, respectively. In infants to school children, eye injuries mainly occurred at home and by unstructured play, whereas in adolescents, they mostly occurred at school and during sports activities. To prevent eye injuries sustained during sports in adolescents, wearing personal protective equipment during high-risk exercise in schools or sports facilities is recommended. | Cho, Jae Wan; Ahn, Jae Yun; Ryoo, Hyun Wook; Moon, Sungbae; Jung, Haewon; Lee, Won Kee; Kim, Jung Ho; Lee, Sang-Hun | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Emergency Med, Daegu, South Korea; Kyungpook Natl Univ, Med Res Collaborat Ctr, Sch Med, Dept Biostat, Daegu, South Korea; Yeungnam Univ, Coll Med, Dept Emergency Med, Daegu, South Korea; Keimyung Univ, Dongsan Med Ctr, Dept Emergency Med, Daegu, South Korea | Moon, Sungbae/F-4010-2015; Kim, Jungho/LDE-9088-2024; Kim, Jung Ho/LDE-9088-2024; Ahn, Jae Yun/N-2652-2017 | 7403536065; 56937505400; 55350557500; 57191584601; 57221554827; 22953484700; 57205704177; 57210919228 | jyahn@knu.ac.kr; | OPHTHALMIC EPIDEMIOLOGY | OPHTHAL EPIDEMIOL | 0928-6586 | 1744-5086 | 29 | 3 | SCIE | OPHTHALMOLOGY | 2022 | 1.8 | 70.2 | 0.63 | 2025-06-25 | 3 | 4 | Children; epidemiology; eye injuries; Republic of Korea | OPEN GLOBE INJURIES; CLINICAL-FEATURES; OCULAR TRAUMA | Children; epidemiology; eye injuries; Republic of Korea | Adolescent; Athletic Injuries; Basketball; Child; Eye Injuries; Female; Humans; Infant; Male; Prospective Studies; Soccer; accident prevention; adolescent; Article; basketball; child; childhood injury; conjunctival hemorrhage; controlled study; contusion; eye injury; eyelid; female; foreign body; home accident; human; hyphema; infant; intraocular foreign body; laceration; major clinical study; male; multicenter study; observational study; orbit fracture; preschool child; prospective study; school; school child; sex difference; soccer; South Korea; teaching hospital; tertiary care center; visual acuity; basketball; clinical trial; complication; eye injury; injury; soccer; sport injury | English | 2022 | 2022-05-04 | 10.1080/09286586.2021.1946826 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Identification of Babesia capreoli from Korean Water Deer in the Republic of Korea | Babesiosis is a tick-borne disease caused by intraerythrocytic protozoa belonging to the genus Babesia that is primarily transmitted through Ixodid ticks and is highly pathogenic to ruminants, horses, pigs, dogs, cats, and in some cases, even humans. Babesia is considered an increasing threat to animal and human health. In this study we report Babesia capreoli infection in Korean water deer (Hydropotes inermis argyropus). Blood samples of 77 wild animals (62 Korean water deer and 15 Korean raccoon dogs [Nyctereutes procyonoides koreensis]) were analyzed to detect Babesia infection. First, PCR was performed to investigate Babesia infection using the partial 18S rRNA gene. Among the 77 wild animals examined, 11 Korean water deer were positive for infection as per the results of sequence analysis. Next, these 11 samples were reanalyzed by PCR using newly designed primers to differentiate between B. capreoli and Babesia divergens. Finally, only one Korean water deer sample was found to be positive for B. capreoli. The nucleotide sequence of this protozoan showed 99.6 - 99.7% identity to those of B. capreoli reported previously. Phylogenetic analysis revealed that the sequence belonged to the B. capreoli clade and diverged from the B. divergens clade. Three nucleotides at positions 631, 663, and 1637 were analyzed to differentiate between B. capreoli and B. divergens. The nucleotides at positions 631 and 1637 were identical to those of B. capreoli, whereas that at position 663 was different. The sequence detected in Korean water deer also exhibited differences at other four positions (669, 704, 711, and 1661) compared with other B. capreoli sequences. This study indicates that Korean water deer serve as a reservoir for B. capreoli. In addition, the primers designed in this study can be used to detect B. capreoli. Future studies should explore the tick vectors that transmit B. capreoli and its pathogenicity. This study was approved by the Institutional Committee of Graduate Studies and Research at Jeonbuk National University, ROK (IACUC decision no.: CBU 2014-00026). | Park, Yu-Jin; Kim, Eun-Mi; Cho, Hyung-Chul; Shin, Seung-Uk; Chae, Joon-Seok; Park, Jinho; Choi, Kyoung-Seong | Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Coll Ecol & Environm Sci, Sangju, South Korea; Seoul Natl Univ, Lab Vet Internal Med, BK PLUS Program Creat Vet Sci Res 21, Res Inst Vet Sci, Seoul, South Korea; Seoul Natl Univ, Coll Vet Med, Seoul, South Korea; Jeonbuk Natl Univ, Coll Vet Med, Iksan, South Korea | 57219426539; 57219722950; 57219427000; 56967385500; 7102478039; 8730126700; 7403949556 | kschoi3@knu.ac.kr; | VECTOR-BORNE AND ZOONOTIC DISEASES | VECTOR-BORNE ZOONOT | 1530-3667 | 1557-7759 | 22 | 3 | SCIE | INFECTIOUS DISEASES;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2022 | 2.1 | 70.3 | 0 | 2025-06-25 | 0 | 0 | Babesia capreoli; Korean water deer; reservoir; tick | REINDEER RANGIFER-TARANDUS; RUPICAPRA-R.-RUPICAPRA; ROE DEER; GENETIC DIVERSITY; PREVALENCE; SPP.; COINFECTION; PATHOGENS; DIVERGENS; RUMINANTS | Babesia capreoli; Korean water deer; reservoir; tick | Animals; Animals, Wild; Babesia; Babesiosis; Deer; Horse Diseases; Horses; Humans; Nucleotides; Phylogeny; Swine; Swine Diseases; Water; nucleotide; water; amplicon; Article; Babesia; Babesia capreoli; Babesia divergens; blood sampling; cladistics; gene location; genetic similarity; measurement accuracy; nonhuman; nucleotide sequence; nucleotide sequence; parasite identification; phylogeny; piroplasmosis; polymerase chain reaction; positivity rate; raccoon dog; RNA sequence; sequence analysis; water deer; animal; deer; genetics; horse; horse disease; human; parasitology; pig; piroplasmosis; swine disease; wild animal | English | 2022 | 2022-03-01 | 10.1089/vbz.2021.0060 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Gene profiling in dorso-ventral patterning of mouse tongue development | Background The tongue is a muscular fleshy organ in the oral cavity that is anatomically divided into the dorsal, ventral, anterior, and posterior part. The intricate tissue organisation and diverse origins of the tongue make it a complex organ of the oral cavity. Objectives To reveal the signalling molecules involved in the formation of the dorsal and ventral parts of the tongue through microarray analysis. Methods Dorsal and ventral tongue tissues were isolated from embryonic day 14 mice by micro-dissection. RNA was extracted from the dorsal and ventral tongue tissues separately for microarray analysis. Microarray data were confirmed by quantitative reverse transcription polymerase chain reaction and whole-mount in situ hybridisation. Results Microarray analysis revealed expression of 33,793 genes. Of these, 931 genes were found to be equally expressed in both the dorsal and ventral parts of the tongue. On limiting the fold-change cut-off to over 1.5-fold, 725 genes were expressed over 1.5-fold in the ventral part and 1,672 in the dorsal part of the tongue. The qPCR and whole-mount in situ hybridisation revealed the expressions of angiopoietin 2 (Angpt2), fibroblast growth factor 18 (Fgf18), mesenchyme homeobox gene1 (Meox1), and SPARC-related modular calcium binding 2 (Smoc2) in the ventral part of the tongue. Conclusions Numerous signalling molecules can be selected from our microarray results to examine their roles in tongue development and disease model systems. In the near future, the selection of candidate genes and their functional evaluations will be performed through loss- and gain-of-function mutation studies. | Kim, Tae-Young; Jung, Hyun-Geuk; Pokharel, Elina; Kim, Ji-Youn; Ha, Jung-Hong; An, Seo-Young; An, Chang-Hyeon; Sohn, Wern-Joo; Jung, Jae-Kwang; Aryal, Yam Prasad; Kim, Jae-Young | Kyungpook Natl Univ, Sch Dent, Dept Biochem, IHBR, Daegu 41940, South Korea; Gachon Univ, Dept Dent Hyg, Incheon, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Conservat Dent, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral & Maxillofacial Radiol, Daegu, South Korea; Daegu Haany Univ, Cosmet & Pharmaceut, Gyongsan, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral Med, Daegu, South Korea | Kim, Ji-Youn/A-5779-2017 | 57208461628; 57841666200; 57220028220; 57157491000; 55549831900; 55258203200; 17134437600; 44161404800; 55970994400; 57202611163; 56812734700 | yparyal86@gmail.com;jykim91@knu.ac.kr; | GENES & GENOMICS | GENES GENOM | 1976-9571 | 2092-9293 | 44 | 10 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;GENETICS & HEREDITY | 2022 | 2.1 | 70.5 | 0.17 | 2025-06-25 | 2 | 2 | Angpt2; Fgf18; Meox1; Microarray analysis; Smoc2; Tongue | EXPRESSION PATTERNS; DIFFERENTIATION; PATHWAYS | Angpt2; Fgf18; Meox1; Microarray analysis; Smoc2; Tongue | Angiopoietin-2; Animals; Calcium; Mice; Organogenesis; RNA; Tongue; a disintegrin like and metallopeptidase with thrombospondin type 1 motif 15; abi gene family binding protein; af4 fmr2 family member 2; angiopoietin 2; bone morphogenetic protein; c1q and necrosis factor related protein 3; ciliary neurotrophic factor receptor; collagen type ix alpha 1; collagen type xi alpha 1; collagen type xii alpha 1; complementary DNA; CXCL13 chemokine; cyclic AMP dependent protein kinase anchoring protein; dermatopontin; diacylglycerol kinase; diacylglycerol kinase kappa; dickkopf 1 protein; digoxigenin; early b cell factor 3; eyes absent 1 homolog; fatty acid binding protein 4; fibroblast activation protein; fibroblast growth factor; fibroblast growth factor 18; homeobox a2; hyaluronan and proteoglycan link protein 1; hypoxanthine phosphoribosyltransferase; inter alpha inhibitor h5; keratocan; leukocyte cell derived chemotaxin 1; MDS1 and EVI1 complex locus protein; melanoma inhibitory activity; mesenchyme homeobox gene 1; microRNA 1224; osteonectin; phosphate regulating endopeptidase homolog; prokineticin receptor 1; protease serine 35; protein; proteoglycan 4; regulator of sex limited protein 1; retinoic acid inducible protein I; rho gtpase activating protein 36; RNA; shisa family member 9; slit robo rho gtpase activating protein 3; sparc related modular calcium binding 2; stromal cell derived factor 1; tenomodulin; testis expressed gene 16; thrombospondin 2; transcription factor; transcription factor 24; transcription factor FOXC1; transcription factor GATA 6; unclassified drug; vasculotropin receptor; vestigial like 2 homolog; zinc finger protein; zinc finger protein 953; angiopoietin 2; calcium; RNA; animal experiment; animal model; animal tissue; Article; controlled study; dorsal-ventral patterning; embryo development; gene expression profiling; gene network analysis; genetic analysis; genome-wide association study; image processing; in situ hybridization; male; microarray analysis; mouse; nonhuman; protein fingerprinting; real time polymerase chain reaction; real time reverse transcription polymerase chain reaction; RNA extraction; tongue; animal; organogenesis; tongue | English | 2022 | 2022-10 | 10.1007/s13258-022-01282-5 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Protective effect of berberine chloride against cisplatin-induced ototoxicity | Background Cisplatin (CP) is an effective anticancer drug broadly used for various types of cancers, but it has shown ototoxicity that results from oxidative stress. Berberine has been reported for its anti-oxidative stress suggesting its therapeutic potential for many diseases such as colitis, diabetes, and vascular dementia. Objective Organ of Corti of postnatal day 3 mouse cochlear explants were used to compare hair cells after the treatment with cisplatin alone or with berberine chloride (BC) followed by CP. Methods We investigated the potential of the anti-oxidative effect of BC against the cisplatin-induced ototoxicity. We observed a reduced aberrant bundle of stereocilia in hair cells in CP with BC pre-treated group. Caspase-3 immunofluorescence and TUNEL assay supported the hypothesis that BC attenuates the apoptotic signals induced by CP. Reactive oxygen species level in the mitochondria were investigated by MitoSOX Red staining and the mitochondrial membrane potentials were compared by JC-1 assay. Results BC decreased ROS generation with preserved mitochondrial membrane potentials in mitochondria as well as reduced DNA fragmentation in hair cells. In summary, our data indicate that BC might act as antioxidant against CP by reducing the stress in mitochondria resulting in cell survival. Conclusion Our result suggests the therapeutic potential of BC for prevention of the detrimental effect of CP-induced ototoxicity. | Kim, Jong-Heun; Baek, Jeong-In; Lee, In-Kyu; Kim, Un-Kyung; Kim, Ye-Ri; Lee, Kyu-Yup | Kyungpook Natl Univ, Coll Nat Sci, Dept Biol, Daegu, South Korea; Kyungpook Natl Univ, Sch Life Sci, BK21 Plus Project, KNU Creat BioRes Grp, Daegu, South Korea; Daegu Haany Univ, Coll Herbal Bioind, Dept Aroma Appl Ind, Gyongsan 38610, South Korea; Kyungpook Natl Univ, Sch Med, Res Inst Aging & Metab, Dept Internal Med, Daegu, South Korea; Kyungpook Natl Univ, Adv Bioresource Res Ctr, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Otorhinolaryngol Head & Neck Surg, Daegu 41944, South Korea | Lee, In-Kyu/AAR-6374-2021; Baek, Jeong-In/AAD-2164-2019; Kim, Ji-Youn/A-5779-2017; Lee, Doh Young/GLR-9586-2022 | 57210338134; 25651687700; 36071537600; 7102248968; 56048344100; 22135779500 | yell_90@knu.ac.kr;kylee@knu.ac.kr; | GENES & GENOMICS | GENES GENOM | 1976-9571 | 2092-9293 | 44 | 1 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY;BIOTECHNOLOGY & APPLIED MICROBIOLOGY;GENETICS & HEREDITY | 2022 | 2.1 | 70.5 | 1.02 | 2025-06-25 | 13 | 12 | Cisplatin; Ototoxicity; Berberine chloride; Antioxidant; ROS | HEARING-LOSS; INFLAMMATION; PREVALENCE; STRESS; DAMAGE | Antioxidant; Berberine chloride; Cisplatin; Ototoxicity; ROS | Animals; Antineoplastic Agents; Apoptosis; Berberine; Caspase 3; Cells, Cultured; Chlorides; Cisplatin; Cochlea; Hair Cells, Auditory; In Situ Nick-End Labeling; Membrane Potential, Mitochondrial; Mice; Organ of Corti; Ototoxicity; Protective Agents; Reactive Oxygen Species; antioxidant; berberine; caspase 3; cisplatin; DNA; phalloidin; protective agent; reactive oxygen metabolite; antineoplastic agent; berberine; caspase 3; chloride; cisplatin; protective agent; animal cell; animal experiment; antioxidant activity; apoptosis; Article; cell survival; controlled study; Corti organ; DNA fragmentation; drug induced disease; explant; fluorescence intensity; hair cell (inner ear); immunofluorescence; mitochondrial membrane potential; mitochondrion; mouse; nonhuman; ototoxicity; stereocilium; TUNEL assay; animal; cell culture; chemistry; cochlea; cochlear hair cell; cytology; drug effect; metabolism; ototoxicity | English | 2022 | 2022-01 | 10.1007/s13258-021-01157-1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Effect of a Precision Cryotherapy Device with Temperature Adjustability on Pigmentation | Background: Pigmentary skin disorders impair the quality of life, leading to the development of therapeutic modalities. However, these treatments should focus more on effectiveness and safety. Aims and Objectives: To evaluate the effect of a temperature-adjustable cryotherapy device on the expression of pigmentation-related biomarkers. Methods and Results: A temperature- and time-adjustable cryotherapy device was employed to improve 200 mJ UVB-induced pigmentation on mice at -5 degrees C (for 5, 10 or 20 s), 0 degrees C (for 5, 10 or 20 s), 5 degrees C (for 5, 10 or 20 s), or 10 degrees C (for 5, 10 or 20 s). Expression of pigmentation-related biomarkers, such as tyrosinase, c-kit, melanocortin 1 receptor and microphthalmia-associated transcription factor before and after treatment with the cryotherapy device was investigated with real-time polymerase chain reaction and immunohistochemistry. Results: Expression of pigmentation-related biomarkers was decreased after the treatment of the temperature-adjustable cryotherapy device. Gene expression of the pigmentation-related biomarkers was decreased under the above conditions with some exception. Protein expression of the pigmentation-related biomarkers showed decreased tendency under the conditions with some exceptions. Conclusion: The temperature-adjustable cryotherapy device used in this study reduced the expression of pigmentation-related biomarkers on mice and may be used to treat patients with skin pigmentation. | Kwock, Mi Hee; Lee, Seongjin; Lee, Eun Nye; Ha, Gi Ung; Kim, Gun-Ho; Lee, Weon Ju | Kyungpook Natl Univ, Sch Med, Dept Immunol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, BK21 FOUR KNU Convergence Educ Program Biomed Sci, Daegu, South Korea; Ulsan Natl Inst Sci & Technol, Dept Biomed Engn, 50 UNIST, Ulsan, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Dermatol, Daegu, South Korea | 57391722600; 59631154300; 57823172400; 57823295200; 35210569700; 59510770800 | gunhokim@unist.ac.kr;weonju@knu.ac.kr; | INDIAN JOURNAL OF DERMATOLOGY | INDIAN J DERMATOL | 0019-5154 | 1998-3611 | 67 | 2 | SCIE | DERMATOLOGY | 2022 | 1.7 | 70.7 | 0.36 | 2025-06-25 | 2 | 2 | Cryotherapy device; pigmentation; UVB | HUMAN-SKIN; NEVUS OTA; MELANOSOME; KERATINOCYTES; MELANOCYTES; BIOLOGY | Cryotherapy device; pigmentation; UVB | melanocortin 1 receptor; microphthalmia associated transcription factor; monophenol monooxygenase; animal experiment; animal model; animal tissue; Article; controlled study; cryotherapy; female; gene expression; immunohistochemistry; mouse; nonhuman; pigment disorder; protein expression; real time polymerase chain reaction; skin pigmentation; temperature; thermodynamics; ultraviolet B radiation | English | 2022 | 2022 (MAR-APR) | 10.4103/ijd.ijd_755_21 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Anti-inflammatory Effect of Wild Indigo (Baptisia tinctoria) Root on Raw 264.7 Cells with Stimulated Lipopolysaccharide | This study tested the anti-inflammatory effect of wild indigo (Baptisia tinctoria) root in Raw 264.7 cells. We prepared two extracts of B. tinctoria: one in water and the other in 50% ethanol. Then we evaluated the toxicities of the B. tinctoria root extracts at 10 to 100 mg mL(-1) concentrations in Raw 264.7 cells and observed 80% cell viability. An anti-inflammatory effect of B. tinctoria root extract in lipopolysaccharide (LPS)-stimulated Raw 264.7 cells was observed with concentrations of 10, 30, and 50 mu g.mL(-1). The results showed that 77.27-66.82% of nitric oxide (NO) production was inhibited by 50 mu g.mL(-1) B. tinctoria root extract. The protein expression of inducible NO synthase (iNOS) expression dramatically decreased by 93.14% and 52.65% in Raw 264.7 cells treated with water and ethanol extracts ofB. tinctoria root, respectively. Moreover, cyclooxygenase-2 (COX-2) protein expression decreased by 42.85% and 69.70% in Raw 264.7 cells treated with water and ethanol extracts of B. tinctoria root, respectively. Furthermore, the mRNA expression of pro-inflammatory markers, such as tumor necrosis factor alpha, interleukin-1 beta, interleukin-6, monocyte chemoattractant protein-1, and prostaglandin E synthase 2, was significantly suppressed in a concentration-dependent manner. Additionally, the B. tinctoria root extracts effectively inhibited enzymes involved in physiological activities. The B. tinctoria root extracts showed excellent anti-inflammatory effects and can be used as a functional material for biological activities. | Sultanov, Akhmadjon; Lee, Eun-Ho; Park, Hye-Jin; Cho, Young-Je | Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea | Sultanov, Akhmadjon/LSL-4834-2024 | 57216320960; 56347429100; 7601567655; 55265396300 | yjcho@knu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 40 | 1 | SCIE | HORTICULTURE | 2022 | 1 | 70.8 | 0.25 | 2025-06-25 | 2 | 2 | cytokine; macrophage; pro-inflammatory; protein expression; real time PCR | NITRIC-OXIDE; SUPPRESSION; EXTRACTS | Cytokine; Macrophage; Pro-inflammatory; Protein expression; Real-time PCR | English | 2022 | 2022 | 10.7235/hort.20220011 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of Salicylic Acid and 1-Methylcyclopropene Treatments on Fruit Quality and Cell Wall Hydrolases of ?Hwangok? Apples During Cold and Shelf-life Storage | We evaluated the effects of salicylic acid (SA) and 1-methylcyclopropene (1-MCP) treatments on fruit quality and the softening-related cell wall materials and hydrolase activities of 'Hwangok' apples during cold storage and cold storage plus seven days under shelf-life storage conditions. Fruits were dipped in a SA solution (3 mM), fumigated with 1-MCP (1 mu L center dot L-1), or subjected to a combined SA+1-MCP treatment, followed by cold storage (0 degrees C) and seven-day shelf-life storage (20 degrees C) for up to 180 and 180 + 7 days. Under both storage conditions, fruits treated with 1-MCP and SA+1-MCP exhibited higher firmness and titratable acidity levels as well as lower internal ethylene concentrations, respiration rates, and weight loss values than the controls and SA-treated apples. The peel color indicators a* and b* were also lower in 1 -MCP-and SA+1-MCP-treated apples than in controls and SA-treated apples. Total sugar and uronic acid levels were increasingly solubilized, and the activities of cell wall hydrolases, except for that of beta-xylosidase, were higher in controls and SA-treated fruits than in 1-MCP and SA+1-MCP-treated apples. Therefore, our results suggest that the 1-MCP treatment is effective for maintaining fruit quality and extending the shelf life of 'Hwangok' apples during cold storage and under shelf-life storage conditions. The SA treatment alone did not extend the storage life of 'Hwangok' apples. | Yoo, Jingi; Kwon, Hye-Won; Kwon, Jung-Geun; Win, Nay Myo; Kang, In-Kyu | Washington State Univ, Tree Fruit Res Extens Ctr, Wenatchee, WA 98801 USA; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea; RDA, Apple Res Inst, Natl Inst Hort & Herbal Sci, Gunwi 39000, South Korea | 56818324500; 57217150999; 57211404168; 42462548000; 56577308800 | kangik@knu.ac.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 40 | 5 | SCIE | HORTICULTURE | 2022 | 1 | 70.8 | 0.25 | 2025-06-25 | 2 | 2 | Additional key Flesh firmness; internal ethylene concentration; softening; total sugar content; uronic acid content | ETHYLENE BIOSYNTHESIS; 1-MCP APPLICATION; CHILLING INJURY; ATTRIBUTES; METABOLISM; PREHARVEST; CULTIVARS | Flesh firmness; internal ethylene concentration; softening; total sugar content; uronic acid content | English | 2022 | 2022 | 10.7235/hort.20220048 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effects of Bloom Thinning with Lime Sulfur on Fruit Set, Yield, and Fruit Quality Attributes of ?RubyS? Apples | Bloom thinning is an important practice that influences the profitability of the orchard. Hence, we assessed the effect of chemical bloom thinning on thinning efficiency and fruit quality of ???RubyS??? apples. Lime sulfur was applied as a bloom thinning agent at 1, 1 + 3, and 2 + 4 days after full bloom (DAFB), and non-bloom thinning trees were used as controls. Compared to the control and bloom thinning treatments at 1 DAFB and 2 + 4 DAFB, the application of bloom thinning at 1 + 3 DAFB greatly decreased the number of fruits per cluster in both terminal and lateral flowers. Although the application of bloom thinning at 2 + 4 DAFB decreased the number of fruits per cluster in the terminal flower, it did not affect the number of fruits per cluster in the lateral flower when compared to the control. At harvest, the number of fruits per tree (fruits/ tree) and yield (kg/ tree) was significantly higher in control trees than in bloom-thinned trees. However, fruit quality attributes including fruit weight and size, flesh firmness, soluble solids content, area of red-blushed surface, and a* value in the fruit were significantly improved by bloom thinning at 1 + 3 DAFB. Therefore, this study suggested that applying bloom thinning at 1 + 3 DAFB could serve as an effective thinning treatment to manage crop load in trees and improve the quality of ???RubyS??? apple fruits. | Win, Nay Myo; Lee, Dongyong; Park, Juhyeon; Song, Yang-Yik; Cho, Young Sik; Lee, Youngsuk; Park, Moo-Yong; Kweon, Hun Joong; Kang, In-Kyu; Nam, Jong-Chul | Natl Inst Hort & Herbal Sci, RDA, Apple Res Inst, Gunwi 39000, South Korea; Kyungpook Natl Univ, Dept Hort Sci, Daegu 41566, South Korea | 42462548000; 57210155771; 57778292600; 56805474200; 55180565600; 57210164168; 56805766300; 50262218300; 56577308800; 50262425400 | namjc@korea.kr; | HORTICULTURAL SCIENCE & TECHNOLOGY | HORTIC SCI TECHNOL | 1226-8763 | 2465-8588 | 40 | 3 | SCIE | HORTICULTURE | 2022 | 1 | 70.8 | 0.76 | 2025-06-25 | 6 | 6 | fruit color; fruit size; fruit weight; lateral flowers; terminal flowers | POLLEN-TUBE GROWTH; CROP LOAD; RETURN BLOOM; GALA APPLE; FUJI; FLOWER; BLOSSOM; TEMPERATURE; NAA | fruit color; fruit size; fruit weight; lateral flowers; terminal flowers | English | 2022 | 2022 | 10.7235/hort.20220024 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
