Article Lysobacter terrigena sp. nov., isolated from a Korean soil sample A bacterial strain isolated from a soil collected in Jeju Island, designated as 17J7-1(T), was Gram-negative, rod-shaped, yellow colored, and motile by gliding. This strain was able to grow at temperature range from 10 to 42 degrees C, pH 7-9, and tolerated up to 1% NaCl. Analysis of 16S rRNA sequence identified strain 17J7-1(T) as a member of the genus Lysobacter with close sequence similarity with Lysobacter mobilis 9NM-14(T) (97.4%), Lysobacter xinjiangensis RCML-52(T) (97.0%), and Lysobacter humi FJY8(T) (96.9%). The genomic DNA G + C content of the isolate was 67.9 mol%. DNA-DNA relatedness between strain 17J7-1(T) and L. mobilis, L. humi, and L. xinjiangensis were 42.3%, 39.5%, and 35.8%, respectively, clearly showing that the isolate is distinct from its closest phylogenetic neighbors in the genus Lysobacter. Average nucleotide identity (ANI) and digital DNA-DNAhybridization (dDDH) values between strain 17J7-1(T) and L. enzymogenes ATCC 29487(T), the type species of this genus, and several other close Lysobacter species were less than 77% and 22%, respectively. Major fatty acids were C-16:0 iso (29.8%), summed feature 9 (C-17:1 iso omega 9c/C-16:0 10-methyl; 20.1%), and C-15:0 iso (17.7%). The predominant respiratory quinone was ubiquinone Q-8 and the major polar lipids were phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol. In the light of the polyphasic evidence accumulated in this study, strain 17J7-1(T) is considered to represent a novel species in the genus Lysobacter, for which name Lysobacter terrigena sp. nov. is proposed. The type strain is 17J7-1(T) (= KCTC 62217(T) = JCM 33057(T)).

Article Methylobacterium segetis sp. nov., a novel member of the family Methylobacteriaceae isolated from soil on Jeju Island A bacterial strain, 17J42-1(T), was isolated from a soil sample collected on Jeju Island, Republic of Korea. Colonies grown on R2A agar were pink in color, and cells were Gram-stain negative, short and rod-shaped. Analysis of 16S rRNA gene sequences identified this strain as a member of the genus Methylobacterium in the family Methylobacteriaceae, with high levels of 16S rRNA sequence similarity shared with Methylobacterium oxalidis 35a(T) (98.6%), Methylobacterium jeotgali S2R03-9(T) (97.5%), and Methylobacterium soli YIM 48816(T) (97.3%). Cells grew at 15-35 degrees C, pH 5-9, and in the presence of 0-1.0% NaCl. The genomic G + C content was 70.2 mol% based on the whole genome analysis. The predominant respiratory quinone was ubiquinone Q-10, the major fatty acid was C-18:1 omega 7c (85.3%), and the major polar lipids were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, and diphosphatidylglycerol. The phenotypic and chemotaxonomic data support the affiliation of strain 17J42-1(T) with the genus Methylobacterium. However, the DNA-DNA relatedness between the isolate and its closest phylogenetic neighbors was lower than 38%. The OrthoANI and dDDH values between strain 17J42-1(T) and the closest type strain Methylobacterium oxalidis NBRC 107715(T) were calculated to be 85.9% and 30.6%, respectively. The results of 16S rRNA gene sequence similarity analysis, DNA-DNA hybridization analysis, and the observed differentiating phenotypic properties from other closely related taxa clearly indicate that strain 17J42-1(T) represents a novel species in the genus Methylobacterium, for which the name Methylobacterium segetis sp. nov. is proposed. The type strain is 17J42-1(T) (= KCTC 62267(T) = JCM 33059(T)).

Review Revisiting the plant growth-promoting rhizobacteria: lessons from the past and objectives for the future Plant beneficial rhizobacteria (PBR) is a group of naturally occurring rhizospheric microbes that enhance nutrient availability and induce biotic and abiotic stress tolerance through a wide array of mechanisms to enhance agricultural sustainability. Application of PBR has the potential to reduce worldwide requirement of agricultural chemicals and improve agro-ecological sustainability. The PBR exert their beneficial effects in three major ways; (1) fix atmospheric nitrogen and synthesize specific compounds to promote plant growth, (2) solubilize essential mineral nutrients in soils for plant uptake, and (3) produce antimicrobial substances and induce systemic resistance in host plants to protect them from biotic and abiotic stresses. Application of PBR as suitable inoculants appears to be a viable alternative technology to synthetic fertilizers and pesticides. Furthermore, PBR enhance nutrient and water use efficiency, influence dynamics of mineral recycling, and tolerance of plants to other environmental stresses by improving health of soils. This report provides comprehensive reviews and discusses beneficial effects of PBR on plant and soil health. Considering their multitude of functions to improve plant and soil health, we propose to call the plant growth-promoting bacteria (PGPR) as PBR.

Article Understanding the Role of Social Media in Political Participation: Integrating Political Knowledge and Bridging Social Capital From the Social Cognitive Approach Recently, the relationship between use of social media and political participation has received increased scholarly scrutiny. Two main elements that reflect theoretical approaches to the relationship have been developed: political knowledge and bridging social capital. The current study integrates political knowledge and bridging social capital, using Bandura's social cognitive theory (SCT) on data collected from surveys conducted in the U.S. The results suggest that self-efficacy and outcome expectancy mediate the effects of political knowledge and bridging social capital on political participation. The proposed model represents the interactions among bridging social capital, political knowledge, self-efficacy, and outcome expectancy, providing an overall mechanism to assess the effects of social media on political participation using SCT.

Article Determination of Gleason score discrepancy for risk stratification in magnetic resonance-ultrasound fusion prostate biopsy Background Magnetic resonance imaging (MRI)-ultrasound (US) fusion biopsy remains challenging and highlights the need towards standardization. Purpose To characterize the clinical and MRI features of clinically significant prostate cancer (csPCa) with discrepant Gleason score (GS) in MRI-US fusion biopsy. Material and Methods A total of 400 consecutive patients with suspected cancer lesions who underwent MRI-US fusion biopsy and subsequent prostatectomy were included. In the comparison of biopsy GS with pathology GS, matched lesions were defined as a GS, and discrepant lesions were defined as an upgrade of the GS. Descriptive statistics were used to define clinical characteristics, including age, prostate-specific antigen (PSA), PSA density, and maximal cancer core length (MCCL). Differences between lesions with matched and discrepant GS were determined considering the location and PI-RADS v2 score. A paired comparison of the volumes between the two groups was performed. Results There were 130 lesions with discrepant GS in 124 patients. There was no significant difference in the age, PSA, and PSA density between the two groups, except for the MCCL (P = 0.028). The lesions were distributed in the peripheral (n = 88) and transition (n = 42) zones; 33, 50, and 47 lesions were at the apex, mid-gland, and base levels, respectively. PI-RADS scores were as follows: 2 (n = 5), 3 (n = 8), 4 (n = 68), and 5 (n = 39). In comparison with matched lesions, discrepant lesions had significantly smaller multiparametric MRI-measured cancer volumes (P < 0.05). Conclusion Knowledge of discrepant GS in MRI-US fusion biopsy is important, and a careful approach is needed to reduce this discrepancy.

Article Acute alcohol consumption-induced let-7a inhibition exacerbates hepatic apoptosis by regulating Rb1 in mice Alcohol consumption is a critical risk factor for hepatic pathogenesis, including alcoholic liver diseases (ALD), but implications of alcohol-induced dysregulation of microRNA (miRNA) in ALD pathogenesis are not completely understood. In the present study, C57BL/6J male mice were treated with saline (CON; oral gavage; n = 8) or alcohol (EtOH; 3 g/kg body weight; oral gavage; n = 8) for 7 days. A total of 599 miRNAs and 158 key mRNAs related to fatty liver and hepatotoxicity pathways were assessed in mice liver tissues. The mRNA expression datasets were then utilized to predict interactions with miRNAs that were changed by alcohol consumption. Predicted miRNA-mRNA interactions were validated using in vitro miRNA transfection experiments. The results showed that let-7a was significantly decreased in the EtOH group and Rb1 mRNA was predicted as a target gene. This was further supported by an inverse correlation of RB1 and let-7a expression in mice liver tissue. Additionally, key protein expressions involved in RB1-apoptosis axis [i.e., p73, cleaved CASP-3 (cCASP-3), and cCASP-7] showed a trend of increase in the EtOH mice; this was also confirmed by capase-3 enzyme activity and terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling assay in livers of mice that had consumed alcohol. In line with our in vivo observations, alcohol treatment suppressed the let-7a expression and subsequently upregulated p73, cCASP-3, and cCASP-7 protein expressions in mice hepatocytes. Additional proteins in the apoptosis regulatory pathway (i.e., MDM2-p53 axis) were significantly changed in response to let-7a suppression in the cells. Taken together, the current study provides mechanistic evidence that alcohol consumption-induced let-7a suppression results in the upregulation of RB1, thereby promoting hepatic apoptosis through induction of pro-apoptotic proteins (e.g., p73), and by, at least in part, preventing MDM2-mediated p53 degradation.

Article Prognostic Value of Cystatin C-Derived Estimated Glomerular Filtration Rate in Patients with Acute Heart Failure Background:Renal function is closely related to cardiac function and an important prognostic marker in heart failure.Objective:We aimed to test the prognostic value of cystatin C (cysC)-derived estimated glomerular filtration rates (eGFR) in comparison with eGFRs from creatinine solely based equations in patients with acute heart failure (AHF).Methods:This study included 262 patients (65.8 +/- 14.9 years old, 126 male) with AHF. Prognostic value of the eGFRs, from cysC-based equations chronic kidney disease epidemiology collaboration (CKD-EPI-cysC and CKD-EPI-creatinine [cr]-cysC equations) were compared with eGFRs calculated from serum creatinine levels only (Modification of Diet in Renal Disease [MDRD]-4 and CKD-EPI-cr equations). Prognosis was evaluated with the composite of all-cause mortality and hospitalization for heart failure within 1 year.Results:During the follow-up period (mean follow-up period, 264.0 +/- 136.1 days), 67 (25.6%) events occurred. Estimated GFR using CKD-EPI-cysC was the best for predicting 1-year outcome using receiver operating characteristic curve analysis (area under curve 0.585, 0.607, 0.669, and 0.652 for eGFRs from MDRD-4, CKD-EPI-cr, CKD-EPI-cysC, and CKD-EPI-cr-cysC respectively). The Kaplan-Meier survival curve analysis showed that only the eGFRs classification from the equations based on cysC significantly predicted 1-year outcome in patients with AHF.Conclusions:Estimated GFRs calculated with cysC predicted the prognosis more accurately in patients with AHF than the eGFRs from creatinine only equations.

Article Gamma Knife Radiosurgery Using Co-Registration with PET-CT and MRI for Recurrent Nasopharyngeal Carcinoma with Previous Radiotherapy : A Single Center 14-Year Experience Objective : We retrospectively evaluated the efficacy of Gamma Knife radiosurgery (GKS) for recurrent nasopharyngeal carcinoma (NPC) in patients who previously underwent radiotherapy, and analyzed the treatment outcomes over 14 years. Methods : Ten patients with recurrent NPC who had previously received radiotherapy underwent stereotactic radiosurgery using a Gamma Knife (R) (Elekta Inc, Atlanta, GA, USA) between 2005 and 2018. The median target volume was 8.2 cm(3) (range, 1.7-17.8), and the median radiation dose to the target was 18 Gy (range, 12-30). The median follow-up period was 18 months (range, 6-76 months). Overall and local failure-free survival rates were determined using the Kaplan-Meier method. Results : The NPCs recurred at the primary cancer site in seven patients (70%), as distant brain metastasis in two (20%), and as an extension into brain in one (10%). The recurrent tumors in seven of the 10 patients (70%) were found on the routine follow-up imaging studies. Two patients presented with headache and one with facial pain. Local failure after GKS occurred in five patients (50%) : two of whom died eight and 6 months after GKS, respectively. No adverse radiation effects were noted after GKS. The 1- and 3-year overall survival rates after GKS were 90% and 77%, respectively. The local failure-free survival rates at 6 months, 1 year, and 3 years after GKS were 80%, 48%, and 32%, respectively. The median interval from GKS to local failure was 8 months (range, 6-12). Univariate analysis revealed that using co-registration with positron emission tomography-computed tomography (PET-CT) and magnetic resonance imaging (MRI) was associated with a lower local failure rate of recurrent NPC (p=0.027). Conclusion : GKS is an acceptable salvage treatment option for patients with recurrent NPC who previously received radiation therapy. PET-CT and MRI co-registration for dose planning can help achieve local control of recurrent NPC.

Article In-Vitro Study of Urokinase Thrombolysis Following Stereotactic Aspiration of Intracerebral Hematoma Objective : A consensus regarding the ideal regimen for urokinase (UK) thrombolysis subsequent to stereotactic spontaneous intracerebral hemorrhage aspiration has yet to be established. The purpose of this study is to evaluate the efficacy of UK thrombolysis relative to when the regimen is changed. Methods : Venous blood from 30 heathy volunteers was obtained for this in-vitro study. Various concentrations of UK solution were added to microcentrifuge tubes containing the clotted blood. The efficacy of UK thrombolysis was identified by checking the weight of lysed hematoma following various time intervals with different concentrations of UK solution. Group one, the "3x4" group involved four administrations every 3 hours over 12 hours, and group two, the "6x2" group involved two administrations every 6 hours over 12 hours. Results : More hematoma was lysed in the 3x4 group than the 6x2 group across all concentration levels (however, the differences were only significant between groups at the 500 and 1000 IU concentration levels, p<0.05). There were no significant differences of lysed hematoma among the various UK solution concentrations within groups. Conclusion : This study suggests that frequent administrations of UK thrombolysis may result in a greater degree of lysed hematoma in comparison to a higher concentration of UK.

Article Prediction of Risk Factors after Spine Surgery in Patients Aged &gt;75 Years Using the Modified Frailty Index Objective : Spine surgery is associated with higher morbidity and mortality rates in elderly patients. The modified Frailty Index (mFI) is an evaluation tool to determine the frailty of an individual and how preoperative status may impact postoperative survival and outcomes. This study aimed to determine the usefulness of mFI in predicting postoperative complications in patients aged >= 75 years undergoing surgery with instrumentation. Methods : We retrospectively reviewed the perioperative course of 137 patients who underwent thoracolumbar-instrumentation spine surgery between 2011 and 2016. The preoperative risk factors were the 11 variables of the mFI, as well as body mass index (kg/cm(2)), preoperative hemoglobin, platelet, albumin, creatinine, anesthesia time, operation time, estimated blood loss, and transfusion amount. The 60-day occurrences of complication rates were used for outcome assessment. Results : Major complications after spinal instrumentation surgery occurred in 34 of 138 patients (24.6%). The mean mFI score was 0.18 +/- 0.12. When we divided patients into a pre-frail group (mFI, 0.09-0.18; n=94) and a frail group (mFI >= 0.27; n=44), only the rate of sepsis was statistically higher in the frail group than in the pre-frail group. There were significantly more major complications in patients with low albumin levels or in patients with infection or who had experienced trauma. The mFI was a more useful predictor of postoperative complications than the American Society of Anesthesiologists physical status score. Conclusion : The mFI can successfully predict postoperative morbidity and mortality in patients aged >= 75 years undergoing spine surgery. The mFI improves perioperative risk stratification that provides important information to assist in the preoperative counselling of patients and their families.

Review Role of Balloon Guide Catheter in Modern Endovascular Thrombectomy Proximal flow control achieved with a balloon guide catheter (BGC) during endovascular treatment of acute ischemic stroke is reviewed in this article. In clinical practice, BGCs offer a multi-faceted approach for clot retrieval by creating proximal flow arrest, reducing embolic burden, and shortening procedure time. Evaluation of frontline thrombectomy procedures with BGCs revealed advantages of combined use over the conventional guide catheter (CGC), notably in the significant reduction of distal emboli to both the affected and previously unaffected territories. Recently, new measures of early and complete reperfusion at first thrombectomy pass have been identified as independent predictors of improved outcomes, which were consistently demonstrated with use of BGC as a safe and effective option to minimize number of passes during intervention. Prior randomized controlled trials reported the positive correlation between BGC-treated patients and a lower risk of mortality as well as shortened procedure time. While BGC use is more common in stent retriever-mediated mechanical thrombectomy, preliminary data has shown the potential benefit of device application during contact aspiration thrombectomy to achieve successful recanalization. However, the question of which major endovascular strategy reigns superior as a frontline remains to be answered. Along with clinical case assessments, BGC performance during in-vitro simulation was analyzed to further understand mechanisms for optimization of thrombectomy technique.

Review Supraorbital Keyhole Approach for Intracranial Aneurysms : Transitioning from Concerns to Confidence For surgical minimalism to reduce iatrogenic traumatization, a supraorbital keyhole approach has already been successfully applied to treat many unruptured anterior circulation aneurysms. However, using this minimal approach also raises several technical concerns due to the small cranial opening and cosmetic impact of a facial incision. Yet, such technical limitations can be overcome by using favorable surgical indications, slender surgical instruments, and optimized surgical techniques, while excellent cosmetic outcomes can be achieved using a short skin incision located <1 cm from the supraorbital margin, reconstruction of any bone defects around the bone flap, and meticulous wound closure. Thus, given such reassuring surgical results, in terms of the clipping status, neurological effects, and cosmetic outcomes, any concerns can be transitioned into confidence.

Article Clinical and radiological outcomes between biportal endoscopic decompression and microscopic decompression in lumbar spinal stenosis Background context: Numerous minimal invasive techniques treating lumbar spinal stenosis have been introduced. Clinical results using biportal endoscopic spinal surgery has recently been introduced as a treatment option for lumbar spinal stenosis. The purpose of this study was to compare the clinical and radiologic outcome between microscopic unilateral laminotomy bilateral decompression and biportal endoscopic unilateral laminotomy bilateral decompression in patients with degenerative lumbar spinal stenosis. Method: A total of 89 patients were evaluated for this study. Only single-level patients were enrolled for accurate comparison. Patients that underwent biportal endoscopic surgery were assigned to Group A, and patients that underwent microscopic surgery were designated Group B. Clinical outcomes were evaluated using modified Macnab criteria, Oswestry Disability Index, and Visual Analog Scale. Postoperative complications were checked until final follow up. Plain radiographs before and after surgery were compared to analyze the change of alignment. Result: There was a significant difference between Group A and B in VAS of back on postoperative 2 months. Other clinical measurements except for postoperative 2 months VAS of back showed no significant difference. There were no significant differences between Group A and Group B regarding preoperative and postoperative radiological findings. Conclusion: Two different decompression techniques preserve the spinal structure and exhibit a favorable clinical outcome and have the advantage of not causing postoperative instability in the short term follow up. Biportal endoscopic surgery may leads to less postoperative back pain than microscopic surgery, which may allow early ambulation and shorter hospitalization period.

Article Cyclic parallel hypersurfaces in complex Grassmannians of rank 2 The object of the paper is to study cyclic parallel hypersurfaces in complex (hyperbolic) two-plane Grassmannians which have a remarkable geometric structure as Hermitian symmetric spaces of rank 2. First, we prove that if the Reeb vector field belongs to the orthogonal complement of the maximal quaternionic subbundle, then the shape operator of a cyclic parallel hypersurface in complex hyperbolic two-plane Grassmannians is Reeb parallel. By using this fact, we classify all cyclic parallel hypersurfaces in complex hyperbolic two-plane Grassmannians with non-vanishing geodesic Reeb flow. Next, we give a non-existence theorem for cyclic Hopf hypersurfaces in complex two-plane Grassmannians.

Article Melatonin inhibits vascular smooth muscle cell proliferation and apoptosis through upregulation of Sestrin2 Excessive vascular smooth muscle cell (VSMC) proliferation contributes to the development of atherosclerosis and restenosis. Furthermore, apoptosis of VSMCs accelerates plaque rupture in the atherosclerotic vessels. Therefore, a strategy that regulates both VSMC proliferation and apoptosis is essential for the development of novel pharmacological tools for the treatment of atherosclerosis. Despite mounting evidence supporting the benefits of melatonin in diverse metabolic diseases, the role of melatonin in VSMC growth remains largely unknown. The present study revealed that melatonin inhibited both proliferation and apoptosis of primary cultured rat VSMCs. Melatonin induced mitochondrial energetic stress in VSMCs and subsequent induction of Sestrin2 via C/EBP beta. Melatonin-induced Sestrin2 suppressed mTORC1 activity in VSMCs, contributing to suppression of VSMC proliferation. Additionally, melatonin-induced upregulation of Sestrin2 blocked apoptosis by preventing excessive ROS generation. The results demonstrated that melatonin controlled VSMC proliferation and apoptosis via Sestrin2-mediated inhibition of mTORC1 and ROS scavenging. Therefore, melatonin should be considered as a lead compound for therapies aimed at preventing vessel lumen constriction during the course of atherosclerosis and restenosis.
