Article Bone Graft Biomineral Complex Coderived from Marine Biocalcification and Biosilicification Bone graft materials have been mainly developed based on inorganic materials, including calcium phosphate. However, these graft materials usually act as osteoconductive rather than osteoinductive scaffolds. To improve bone reconstruction, a combination of several materials has been proposed. However, there are still no alternatives that can completely replace the existing animal-derived bone graft materials. In this work, a marine-inspired biomineral complex was suggested as a potential bone graft material. The proposed biosilicified coccolithophorederived coccoliths using bioengineered mussel adhesive proteins show osteopromotive ability through the synergistic effects of osteoconductivity from calcium carbonate and osteoinductivity from silica. Its possibility of use as a bone substitute was determined by evaluating the in vitro osteogenic behaviors of multipotent mesenchymal stem cells and in vivo bone regeneration in a rat calvarial defect model. Therefore, the marine-inspired biomineral complex developed in this study could be successfully used for bone tissue engineering.

Note Breast cancer with asymptomatic metastasis to the gallbladder Introduction: Breast cancer is the most frequent malignant tumors among female and it is usually associated with metastasis to lungs, bones, liver, and brain. The gallbladder as the site of metastasis from breast carcinoma is extremely rare, and only a few such case reports have been published to date. Methods: We report the case of a 59-year-old woman diagnosed with breast cancer who underwent cholecystectomy for an incidental finding of gallbladder wall thickening on computed tomography. Results: A 59-year-old menopausal woman presented with a lump in her right breast for one months. Breast examination revealed an ill-defined palpable area in the right breast. Ultrasonography (US) of the right breast revealed 28 mm × 19 mm sized irregular hypoechoic mass in the retro-areolar area. This was followed by a US-guided Tru-cut biopsy of the right breast lesion and axillary nodes, which revealed invasive lobular carcinoma. The tumour was positive for oestrogen receptors. Computer tomography showed a wall a thickening in the fundus and body of the gallbladder with multiple gallstones. A single port laparoscopic cholecystectomy was performed, and the postoperative course was uneventful. Histopathology of the gallbladder revealed involvement by an invasive lobular carcinoma. Conclusions: Metastatic gallbladder involvement is rare, especially in a case of primary breast cancer and It is difficult to suspect a metastatic localization from primary breast cancer in the breast cancer. Even if there is no gastrointestinal symptoms, it is necessary to be well aware of the possibility of metastasis in patients with if imaging reveals gallbladder abnormalities. © The Korean Association of Hepato-Biliary-Pancreatic Surgery.

Article Bridging the intracranial pressure gap: a smooth transition strategy for slit ventricle syndrome Slit ventricle syndrome (SVS) is a well-known complication of long-standing shunts. Patients develop intermittent severe headache, vomiting with other symptoms of increased intra-cranial pressure. Brain computed tomography (CT) usually reveals slit-like ventricles with nearly obstructed proximal catheters. Treatment for SVS usually involves upgrading the shunt valve pressure setting. Currently, many patients carry programmable shunts and pressure setting can be adjusted noninvasively. However, when the programmable valve pressure setting is upgraded, some patients with SVS experience worsened symptoms. This is caused by the time gap between ICP increase and real ventricular expansion (and freeing proximal catheter) after shunt upgrading. Therefore, it is important to control a patient's symptoms during the transition period. We report our experience in controlling ICP in a patient with SVS using external ventricular drainage.

Article Ca(OH)2 apexification of pulp necroses of the permanent incisors in a case of X-linked hypophosphataemic rickets-the 60-month check-up: A case report X-linked hypophosphataemic rickets is a hereditary metabolic disorder. The dental features include abscesses and swelling without caries or trauma. We present a case of familial hypophosphataemic rickets in an 11-year-old boy followed up for 60 months. We describe the treatment of multiple pulp necroses with apical periodontitis. Multiple pulp necroses with apical periodontitis were diagnosed in the anterior teeth. Ca(OH)(2) apexification was performed; healing was evident over the next 60 months. The incisors, canines, and premolars exhibited shortened roots. To prevent pulp necrosis, regular checkups included applications of fissure sealant and fluoride, vital testing, and radiography. The canines and premolar pulps retained vitality. Ca(OH)(2) apexification followed by preventative follow-up was successful. The prognosis at the 60-month check-up was good. (C) 2021 Japanese Society of Pediatric Dentistry.

Article Calculation of beam quality correction factor for relative positions of SOBP and ionization chamber using Monte Carlo simulations In proton radiotherapy, the dosimetry protocol TRS-398 does not provide the beam quality correction factors kQ,Q0 for all areas of the spread out Bragg peak (SOBP). Monte Carlo simulations using the TOPAS simulation toolkit were performed to calculate the beam quality correction factors at various depths of the SOBP to observe any variations. The SOBP of the generated proton beam had a range of 15 cm and a width of 15 cm. The beam quality correction factors kQ,Q0 were calculated not only at the reference depth of 7.5 g/cm2 recommended by TRS-398 but also at depths of 4 g/cm2 and 13 g/cm2. The comparison of the simulation results for the absorbed dose with actual measurements showed a slight difference at the surface above the water phantom, but the width of the SOBP was well matched with a difference of less than 1%. The kQ,Q0 factor calculated at the reference depth of 7.5 g/cm2 was 1.045, which is within the error range of the value of 1.030 provided by the TRS-398 protocol. The kQ,Q0 factors calculated at the depths of 4 g/cm2 and 13 g/cm2 were 1.041 and 1.048, respectively. While all the calculated values were within the error range of the value suggested by TRS-398, the observed increase in the kQ,Q0 factor with increasing depth suggests that a position-dependent beam quality correction factor determined through precise measurements may be required to calculate the correct dose. © 2021 The Korean Physical Society.

Conference paper Camera image quality tradeoff processing of image sensor re-mosaic using deep neural network Recently, with the release of 108 mega pixel resolution image sensor, the photo quality of smartphone camera, including detail, and texture, is getting much higher. This became possible only because by utilizing the remosaic technology which re-organize color filter arrays into the Bayer patterns compatible to existing Image Signal Processor (ISP) of commodity AP. However, the optimized parameter configurations of the remosaic block require lots of efforts and long tuning period in order to secure the desired image quality level and sensor characteristics. This paper proposes a deep neural network based camera auto-tuning system for the remosaic ISP block. Firstly, considering the learning phase, big image quality database is created in the random way using reference image and tuning register. Second, the virtual ISP model has been trained in order that predicts image quality by changing sensor tuning registers. Finally, the optimization layer generates the sensor remosaic parameters in order to achieve the user's target image quality expectation. By experiment, the proposed system has been verified to secure the image quality at the level of professionally hand-tuned photography. Especially, the remosaic artifact of false color, color desaturation and line broken artifacts are improved significantly by more than 23%, 4%, and 12%, respectively. © 2021, Society for Imaging Science and Technology Kim, Younghoon; Lee, Jungmin; Kim, SungSu; Bang, Jiyun; Hong, Dagyum; Kim, TaeHyung; Yim, JoonSeo Samsung Electronics Co.

Article Carboxymethyl Chitosan Promotes Migration and Inhibits Lipopolysaccharide-Induced Inflammatory Response in Canine Bone Marrow-Derived Mesenchymal Stem Cells The study was conducted to evaluate the effects of carboxymethyl chitosan (CMC) on proliferation, migration, and lipopolysaccharide (LPS)-induced inflammatory response in canine bone marrow-derived mesenchymal stem cells (BMSCs). The proliferation and migration of BMSCs were examined after treatment with CMC. The effect of CMC on the mRNA expression of inflammatory cytokines, such as interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, IL-10, and transforming growth factor (TGF)-β, was also evaluated by reverse transcription polymerase chain reaction (RT-PCR). In the proliferation assay, no significant changes were found at all CMC concentrations compared with controls. The migration assay showed that CMC dose-dependently stimulated the migration of BMSCs in normal and LPS-treated conditions. RT-PCR showed that TNF-α and IL-10 expressions were suppressed in the BMSCs after CMC treatment. However, other genes were not affected. Taken together, CMC promoted BMSC migration and inhibited TNF-α and IL-10. Therefore, CMC may be possible to regulate wound healing when mesenchymal stem cells are applied in inflammatory diseases. © The Korean Society of Veterinary Clinics.

Review Cellulose and its derivatives for application in 3D printing of pharmaceuticals Background Three-dimensional printing (3DP) has emerged as an advanced manufacturing technology capable of producing complex yet precise medicines intended for patient-centric drug therapy. However, printable materials currently available for 3DP are far too limited. Area covered The current article covers various cellulose-based polymers as well as their applications, especially in 3DP of oral solid dosage forms. The review focuses on their physicochemical properties, roles, and functions in conventional as well as 3DP dosage forms, and the characteristics of the obtained printed products are discussed. In addition, the challenges and considerations for processing cellulose-based feedstock materials are briefly presented. Expert opinion Cellulose and its derivatives are regarded as suitable polymers with a huge potential for applications in 3DP drug delivery systems. It is therefore essential to better understand cellulose-based printable polymers and their applications in 3DP.

Article Cervical epidural hematoma with Brown-Sequard syndrome caused by an epidural injection: a case report Epidural hematoma with Brown-Sequard syndrome caused by an epidural injection is a rarely found condition in the emergency department (ED). We report an unusual case of Brown-Sequard syndrome in a 55-year-old man who presented at the ED with right-sided weakness and contralateral loss of pain and temperature sensation after a cervical epidural injection for shoulder pain. Cervicla spine magnetic resonance imaging showed an epidural hematoma from C4 to C6. After admission, his right hemiparesis and contralateral sensory loss improved within eight days, and surgical decompression was not required. Diagnosing spinal lesions in the ED is challenging, especially in patients with acute neurological signs requiring immediate evaluation for stroke. In this case, definite hemiparesis and some contralateral sensory loss were noted. Therefore, a potential spinal lesion was suspected rather than a stroke. This case emphasized the importance of conducting a focused neurological examination after history taking.

Proceedings Paper Challenges and Applications of Face Deepfake With the development of Generative deep learning algorithms in the last decade, it has become increasingly difficult to differentiate between what is real and what is fake. With the easily available "Deepfake" applications, even a person with less computing knowledge can also produce realistic Deepfake data. These fake data have many benefits while on the other hand, it can also be used for unethical and malicious purposes. Deepfake can be anything fake data generated by using deep learning methods. In this study, we focus on Deepfake with respect to face manipulation. We represent the currently used algorithms and datasets are represented for creating Deepfake. We also study the challenges and the real-world applications in which the benefits, as well as the drawbacks of using Deepfake, are being pointed out.

Article Change point analysis in Bitcoin return series : a robust approach Over the last decade, Bitcoin has attracted a great deal of public interest and Bitcoin market has grown rapidly. One of the main characteristics of the market is that it often undergoes some events or incidents that cause outlying observations. To obtain reliable results in the statistical analysis of Bitcoin data, these outlying observations need to be carefully treated. In this study, we are interested in change point analysis for Bitcoin return series having such outlying observations. Since these outlying observations can affect change point analysis undesirably, we use a robust test for parameter change to locate change points. We report some significant change points that are not detected by the existing tests and demonstrate that the model allowing for parameter changes is better fitted to the data. Finally, we show that the model with parameter change can improve the forecasting performance of Value-at-Risk.

Article Changes in Iridocorneal Angle Configuration and Intraocular Pressure during Smartphone Use under Room Light Purpose: To investigate changes in intraocular pressure (IOP) and iridocorneal angle (ICA) configuration during smartphone use under room light. Methods: We included healthy adults aged 19-35 years with no ophthalmological abnormalities. All read text on a smartphone for 6 minutes under room light. IOP was measured via rebound tonometry at baseline and at 2, 4, and 6 minutes. ICA images were obtained via anterior segment optical coherence tomography after each IOP measurement. After 6 minutes, participants stopped reading text and rested for 2 minutes. IOP was then measured again. Results: The IOP significantly increased at 2, 4, and 6 minutes of reading compared to baseline (p < 0.001) but recovered to baseline after 2 minutes of rest (p = 1.000). The anterior chamber depth decreased significantly, and the anterior chamber angle width increased after 6 minutes of smartphone reading (both p < 0.05). Conclusions: IOP increased when reading smartphone text under room light but the ICA did not change. Prolonged smartphone reading is inappropriate for a patient at risk of glaucoma or glaucoma progression. Such patients should be cautioned.

Article Changes in serum protein electrophoresis profiles and acute phase proteins in calves with diarrhea Calf diarrhea leads to substantial economic losses in the livestock industry worldwide due to medical treatment costs, retarded growth performance, and even death. The objective of this study was to investigate changes in serum protein profiles and acute phase proteins in calves with diarrhea and identify the association between these changes and diarrhea. A total of 185 Korean beef calves were used and divided into 3 groups by age: 1 to 10 days (n = 46), 11 to 20 days (n = 65), and 21 to 30 days (n = 74). Blood and fecal samples were collected from each calf. Serum concentrations of total protein, protein fractions (albumin, α1-globulin, α2-globulin, β-globulin, and γ-globulin), haptoglobin (Hp), and serum amyloid A (SAA) were analyzed. Compared to calves without diarrhea, calves with diarrhea had significantly lower albumin concentrations at 11 to 20 days and 21 to 30 days of age (P = 0.017 and P = 0.000, respectively) and significantly higher α1-globulin fractions at 21 to 30 days of age (P = 0.01). Interestingly, α2-globulin fractions were significantly higher in diarrheic calves in all age groups, whereas γ-globulin fractions were significantly lower in calves with diarrhea aged 1 to 10 days, compared with normal animals. In calves with diarrhea, the concentration of Hp was significantly higher, whereas SAA levels were not different between normal and diarrheic calves. In addition, a positive correlation was found between α2-globulin and Hp (P = 0.0004). Taken together, these results provide useful information about the use of serum protein profiles and Hp as prognostic and diagnostic markers for animal health status. © 2021, Canadian Veterinary Medical Association.
