Multicopper oxidases (MCOs) use copper ions as cofactors to oxidize a variety of substrates while reducing oxygen to water. MCOs have been identified in various taxa, with notable occurrences in fungi. The role of these fungal MCOs in lignin degradation sparked an interest due to their potential for application in biofuel production and various other industries. MCOs consist of different protein domains, which led to their classification into two-, three- and six-domain MCOs. The previously established Laccase and Multicopper Oxidase Engineering Database (https//lcced.biocatnet.de) was updated and now includes 51 058 sequences and 229 structures of MCOs. Sequences and structures of all MCOs were systematically compared. All MCOs consist of cupredoxin-like domains. Two-domain MCOs are formed by the N- and C-terminal domain (domain N and C), while three-domain MCOs have an additional domain (M) in between, homologous to domain C. The six-domain MCOs consist of alternating domains N and C, each 3 times. Two standard numbering schemes were developed for the copper-binding domains N and C, which facilitated the identification of conserved positions and a comparison to previously reported results from mutagenesis studies. Two sequence motifs for the copper binding sites were identified per domain. Their modularity, depending on the placement of the T1-copper binding site, was demonstrated. Protein sequence networks showed relationships between two- and three-domain MCOs, allowing for family-specific annotation and inference of evolutionary relationships.

Pediatric organ donation after circulatory determination of death (DCD) is increasingly explored in pediatric transplantation, as it increases the availability of organ grafts. A 6-year-old Caucasian boy with a history of arteriovenous malformation presented with a catastrophic intracranial bleed, resulting in severe brainstem dysfunction despite maximal medical and surgical measures. He did not fulfill the criteria for brain death, which must be met for pediatric organ donation in Singapore. Due to parental request, his organs were donated after withdrawal of life support and determination of death by circulatory criteria. Pediatric organ DCD poses many challenges in the pediatric population, especially in the absence of a local practice guideline. We present the first case of a pediatric organ DCD that has occurred in Singapore. Further work is needed, particularly in establishing a national policy for pediatric organ DCD and increasing overall awareness and acceptance toward pediatric organ donations.Background and purpose Diffusion tensor imaging (DTI) is a promising approach to detect the underlying brain pathology. These alterations can be seen in several diseases such as multiple sclerosis. Tract-based spatial statistics (TBSS) is an easy to use and robust way for analyzing diffusion data. The effect of acquisition parameters of DTI on TBSS has not been evaluated, especially the number of diffusion encoding directions (NDED), which is directly proportional with scan time. Methods We analyzed a large set of DTI data of healthy controls (N = 126) and multiple sclerosis patients (N = 78). The highest NDED (60 directions) was reduced and a tensor calculation was done separately for every subset. We calculated the mean and standard deviation of DTI parameters under the white matter mask. Moreover, the FMRIB Software Library TBSS pipeline was used on DTI images with 15, 30, 45, and 60 directions to compare differences between groups. Mean DTI parameters were compared between groups as a function of NDED. Results The mean value of FA and AD decreased with increasing number of directions. This was more pronounced in areas with smaller FA values. RD and MD were constant. The skeleton size reduced with elevating NDED along with the number of significant voxels. The TBSS analysis showed significant differences between groups throughout the majority of the skeleton and the group difference was associated with NDED. Conclusion Our results suggested that results of TBSS depended on the NDED, which should be considered when comparing DTI data with varying protocols.Merkel cell carcinoma (MCC) is a rare but aggressive non-melanoma skin cancer with significant morbidity and mortality. Treatment of choice for primary and locoregional MCC is complete surgical removal with sentinel lymphonodectomy and post-surgical radiotherapy of tumor basin and locoregional lymph nodes. In non-resectable and advanced tumors, drug therapy is indicated. While cytotoxic chemotherapy has resulted in higher response rates, overall survival remained nearly unaffected. With a better insight into tumor development and biology, new treatment s became available. Immune checkpoint inhibitors result in durable responses with a better safety profile that classical combined chemotherapy. Combinations of immune checkpoint inhibitors with and without radiotherapy help to overcome acquired drug-resistance. New compounds for vaccination and oral use are on the horizon. this website Despite all progress, treatment of MCC remains a challenge that needs close interdisciplinary teamwork.

In January 2020, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was identified to be the causative novel coronavirus for the cluster of patients suffering from pneumonia in China. The disease was later named as coronavirus disease (COVID-19) and was declared a pandemic by the World Health Organization on March 11, 2020. Several studies, since then, have tried to study and explain the origin of SARS-CoV-2, its structure and pathogenicity, epidemiology, modes of transmission, spectrum of illness and causes of mortality and morbidity. The current management strategies focus on supportive care and prevention of complications. With no definite treatment, as of now, encouraging reports of some anti-viral and anti-malarial drugs in the management of COVID-19 generate some hope. This review intends to cover the current known aspects of COVID-19 and SARS-CoV-19, based on the available literature.Background Right ventricular (RV) function is a prognostic marker of chronic thromboembolic pulmonary hypertension (CTEPH). We used two-dimensional (2D) speckle-tracking echocardiography (STE) to evaluate the therapeutic effects of balloon pulmonary angioplasty (BPA) in CTEPH patients. Methods A total of 46 CTEPH patients who underwent 2D STE before and after BPA were enrolled in this retrospective study. The following RV functional parameters were measured tricuspid annular plane systolic excursion (TAPSE), right ventricular fractional area change (RVFAC), RV index of myocardial performance (RIMP), and free wall longitudinal strain (RVFWLS). Satisfactory BPA was defined as mean pulmonary arterial pressure (mPAP) 10 mm Hg after BPA. Patients were divided into two groups according to mPAP values group I had satisfactory BPA outcomes; group Ⅱ had unsatisfactory BPA outcomes. The area under the curve (AUC) of the receiver operating characteristic (ROC) curve was used to determine the optimal cutoff values and the ability of RVFWLS to predict successful BPA outcomes. Results After BPA, SPAP measured by echocardiography (SPAPecho ) and RIMP decreased, but TAPSE, RVFAC, and RVFWLS increased. Before BPA, group Ⅰ had significantly better RV function than group Ⅱ. Multifactor logistic regression analysis identified RVFWLS as an independent factor associated with satisfactory BPA outcomes. The optimal cutoff value for RVFWLS in predicting satisfactory BPA outcomes was -12.2%. Conclusions Balloon pulmonary angioplasty improves RV function in CTEPH patients. RVFWLS is a valuable noninvasive tool with which to assess the treatment effects of BPA. CTEPH patients with lower RVFWLS may have limited benefit from BPA.Aim and objectives To explore whether nursing student's experiences at Recovery Camp have impacted their current nursing practices. Background Recently, there has been a move toward more holistic models of nursing care, which seek to break down barriers of stigmatisation and embrace the tenets of self-determination, to acknowledge people with lived experiences of mental illness and their ability to manage their recovery. In that regard, future health professionals such as nursing students, will need to be educated in a manner that recognises the importance of lived experience. In this paper, we propose that Recovery Camp, an alternative clinical placement setting model, enhances clinical practice in multiple domains and is beneficial for both nursing practitioners and people with lived experiences of mental illness, as well as offering an effective non-traditional alternative to conventional clinical placement opportunities. Methods This study employed a phenomenological research design, involving individual roach may have wider implications for nursing education.Mammary myoepithelial cells have been under-recognized for many years since they were considered less important in breast cancer tumorigenesis compared to luminal epithelial cells. However, in recent years with advances in genomics, cell biology, and research in breast cancer microenvironment, more emphasis has been placed on better understanding of the role that myoepithelial cells play in breast cancer progression. As the result, it has been recognized that the presence or absence of myoepithelial cells play a critical role in the assessment of tumor invasion in diagnostic breast pathology. In addition, advances in screening mammography and breast imaging has resulted in increased detection of ductal carcinoma in situ and consequently more diagnosis of ductal carcinoma in situ with microinvasion. In the present review, we discuss the characteristics of myoepithelial cells, their genomic markers and their role in the accurate diagnosis of ductal carcinoma in situ with microinvasion. We also share our experience with reporting of various morphologic features of ductal carcinoma in situ that may mimic microinvasion and introduce the term of ductogenesis.This is a case of coccidioidomycosis in a dog, examined for vomiting and labored breathing. Physical examination and thoracic and abdominal imaging revealed pleural and peritoneal effusions, both of which exhibited neutrophilic inflammation with a substantial eosinophilic component. The dog had positive IgM and IgG coccidioidomycosis titers at initial evaluation. The eosinophilic component of the inflammation was attributed to coccidioidomycosis. The dog underwent approximately 6 months of fluconazole treatment, with both effusions and clinical signs improving after 6 weeks. Three months after cessation of antifungal treatment, the dog developed a mid-diaphyseal lytic and proliferative lesion in the left radius caused by Coccidioides spp. This case illustrates the importance of consideration of coccidioidomycosis when an eosinophilic cavitary effusion is present in dogs that live in or have traveled to endemic regions.
