Retinopathy of prematurity (ROP) is a major cause of childhood blindness in the world and is caused by oxygen-induced damage to the developing retinal vasculature, resulting in hyperoxia-induced vaso-obliteration and subsequent delayed retinal vascularization and hypoxia-induced pathological neovascularization driven by vascular endothelial growth factor (VEGF) signaling pathway in retina. Current anti-VEGF therapy has shown some effective in a clinical trial, but is associated with the unintended effects on delayed eye growth and retinal vasculature development of preterm infants...

AIM: Direct oral anticoagulants (DOACs) have shown non-inferiority to warfarin for stroke prevention in non-valvular atrial fibrillation (AF) and a more promising safety profile. Unanswered safety aspects remain to addressed and available evidence on the risk associated with these drugs are conflicting. In order to contribute to the debate on their safety profile, we conducted a comparative analysis of the reports of suspected adverse drug reactions (ADRs) associated with DOACs in VigiBase...

Pharmacological neuroenhancement (PNE) is a form of abuse and has not yet been addressed by methods of pharmacovigilance. In the present study, we tested if quantitative signal detection may be sensitive in regards to PNE. We evaluated the risk of drug abuse and dependence (DAAD) related to substances that are known to be used for PNE and divided this group into agents with (methylphenidate) and without a known abuse potential outside the field of PNE (atomoxetine, modafinil, acetylcholine esterase inhibitors, and memantine)...

BACKGROUND: Reoperations occur frequently after initial lumpectomy for breast cancer. The authors hypothesized that the receipt of neoadjuvant chemotherapy (NAC) is associated with fewer reoperations. METHODS: The association between timing of chemotherapy and reoperation rates (ROR) after lumpectomy was investigated for patients with stages 1-3 breast cancer in the National Cancer Database (NCDB) from 2010 to 2013 by multivariable logistic regression modeling. Then propensity score-matching was performed...

MOTIVATION: The PAM50 classifier is used to assign patients to the highest correlated breast cancer subtype irrespectively of the obtained value. Nonetheless, all subtype correlations are required to build the risk of recurrence (ROR) score, currently used in therapeutic decisions. Present subtype uncertainty estimations are not accurate, seldom considered or require a population-based approach for this context. RESULTS: Here we present a novel single-subject non-parametric uncertainty estimation based on PAM50's gene label permutations...

Chongdo Park, Se-Hyun Kim, Sanghoon Ki, Taekyun Ha, Boklae Cho
Steels are commonly used materials in the fabrication of vacuum systems because of their good mechanical, corrosion, and vacuum properties. A variety of steels meet the criterion of low outgassing required for high or ultrahigh vacuum applications. However, a given material can present different outgassing rates depending on its manufacturing process or the various pretreatment processes involved during the fabrication. Thus, the measurement of outgassing rates is highly desirable for a specific vacuum application...

CD8(+) T cells that express retinoic acid-related orphan receptor (ROR)γt (TC17 cells) have been shown to promote procarcinogenic inflammation and contribute to a tolerogenic microenvironment in tumors. We investigated their phenotype and functional properties in relationship to the pathogenesis of human distal bile duct cancer (DBDC). DBDC patients had an elevated level of type 17 immune responses and the frequency of CD8(+)RORγt(+) T cells (TC17 cells) was increased in peripheral blood. The CD8(+)RORγt(+) T cells represented a highly activated subset and produced IL-17A in equal amount as CD4(+)RORγt(+) T cells (TH17 cells)...

MicroRNAs (miRNAs) are small single stranded RNA sequences involved in post-transcriptional regulation of different biological and physiological processes. Paracoccidioidomycosis (PCM) is an infection caused by Paracoccidioides brasiliensis, and it is a major cause of mortality due to systemic mycoses in Brazil. To date, there have been few reports on the role of miRNAs in the immune response against fungi, especially PCM. The objective of this study was to evaluate the differential expression of miRNAs related to the inflammatory response associated with pulmonary infection by P...

 Typical antipsychotics are easily expressed as adverse events such as extrapyramidal symptom (EPS). On the other hand, incidence of adverse events due to atypical antipsychotics is low. Therefore, currently, atypical antipsychotics are widely used to treat schizophrenia. However, it has been reported that there is no difference in the frequency of EPS in atypical and typical antipsychotics. This study aimed to evaluate the expression profile of EPS in atypical and typical antipsychotics treatment using the Japanese Adverse Drug Event Report (JADER) database...

Recent studies have linked a deadly form of prostate cancer known as metastatic castration-resistant prostate cancer (mCRPC) to retinoic acid-related orphan-receptor gamma (ROR-γ). Most of these studies continued to place ROR-γ as orphan because of unidentifiable inhibitor. Recently identified inhibitors of ROR-γ and their therapeutic potential were evaluated, among which inhibitor XY018 was the potent. However, molecular understanding of the conformational features of XY018-ROR-γ complex is still elusive...

AIMS: Acute kidney injury (AKI) is associated with a high hospitalization rate, accelerated long-term decline in kidney function and a high mortality rate. Adverse drug reactions (ADRs) constitute one of the most important modifiable factors in the context of AKI. Most studies of drug-induced AKI have focused on a sole drug class. The objective of the present study was to establish a comprehensive overview of drug-induced AKI on the basis of spontaneously reported ADRs in the French national pharmacovigilance database (FPVD)...

Plasmablastic B-cell malignancies include plasmablastic lymphoma and subsets of multiple myeloma and diffuse large B-cell lymphoma (DLBCL). These diseases can be difficult to diagnose and treat, and lack well-characterised cell line models. Here, immunophenotyping and FOXP1 expression profiling identified plasmablastic characteristics in DLBCL cell lines HLY-1 and SU-DHL-9, associated with CTNNAL1, HPGD, RORα, IGF1 and/or vitamin D receptor (VDR) transcription. We demonstrated VDR protein expression in primary plasmablastic tumour cells, and confirmed in cell lines expression of both VDR and the metabolic enzyme CYP27B1, which catalyses active vitamin D3 production...
