Inflammation is a physiological response of defense but may also represent a potential pathological process in neurological diseases. In this regards, microglia have a crucial role upon either progression or amelioration of degenerative neuronal damage. Because of the role of hypoxia in proinflammatory mechanisms in the nervous system, and the ...

Regulatory T cells (Tregs) have been identified as immunomodulatory cells, which induce tolerance. Evidence from numerous recent studies implicates these cells as critical for maternal tolerance to the fetal-derived placenta, proper functioning of which is required for normal gestation and growth and development of the fetus in utero. This review ...

There has been a recent growth in developments of multivariate meta-analysis. We extend the methodology of Bayesian multivariate meta-analysis to the situation when there are more than two outcomes of interest, which is underexplored in the current literature. Our objective is to meta-analyse summary data from multiple outcomes simultaneously, accounting ...

In this paper, we proposed to utilize a novel spatio-spectral filter, common spatio-spectral pattern (CSSP), to improve the classification accuracy in identifying intended motions based on low-density surface electromyography (EMG). Five able-bodied subjects and a transradial amputee participated in an experiment of eight-task wrist and hand motion recognition. Low-density (six ...

Aspergillus nidulans responds to light in several aspects. The balance between sexual and asexual development as well as the amount of secondary metabolites produced is controlled by light. Here, we show that germination is largely delayed by blue (450 nm), red (700 nm), and far-red light (740 nm). The largest effect was observed ...

Alternative splicing was discovered simultaneously with splicing over three decades ago. Since then, an enormous body of evidence has demonstrated the prevalence of alternative splicing in multicellular eukaryotes, its key roles in determining tissue- and species-specific differentiation patterns, the multiple post- and co-transcriptional regulatory mechanisms that control it, and its ...

Most children, adolescents and young adults with acute lymphoblastic leukaemia (ALL) in first complete remission (CR1) have an excellent prognosis with multi-agent chemotherapy in induction, consolidation, re-induction and maintenance therapy. However, there is a subset of patients with a more guarded prognosis using this approach, who may benefit from haematopoietic ...

ABSTRACT: BACKGROUND: Interferon-gamma (IFN-gamma) and interleukin-6 (IL-6) are multifunctional cytokines that regulate immune responses, cell proliferation, and tumour development and progression, which frequently have functionally opposing roles. The cellular responses to both cytokines are activated via the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway. During the past 10 ...

Here we report a method for highly reproducible chronoamperometric analysis of the contents of microdroplets. Aqueous microdroplets having volumes on the order of 1 nL and separated by a fluorocarbon solvent are generated within a microfluidic device using a T-shaped junction. The key finding is that stable and reproducible quasi-steady-state ...

In tomographic medical imaging, a signal activity is typically estimated by summing voxels from a reconstructed image. We introduce an alternative estimation scheme that operates on the raw projection data and offers a substantial improvement, as measured by the ensemble mean-square error (EMSE), when compared to using voxel values from ...

A melody's identity is determined by relations between consecutive tones in terms of pitch and duration, whereas surface features (i.e., pitch level or key, tempo, and timbre) are irrelevant. Although surface features of highly familiar recordings are encoded into memory, little is known about listeners' mental representations of melodies heard ...

Seed dispersal by ants (myrmecochory) can be influenced by changes to ant assemblages resulting from habitat disturbance as well as by differences in disperser behaviour. We investigated the effect of habitat disturbance by fire on the dispersal of seeds of a myrmecochorous shrub, Pultenaea daphnoides. We also investigated the consequence ...

Abstract Hyperthyroidism is not a rare entity in pregnancy and 85% of these cases attributed to Graves' disease (GD). There is no therapeutic modality for GD considered as totally safe in pregnancy. Fetal and neonatal risks of maternal hyperthyroid disease are related to the hyperthyroidism itself and/or to the medical ...

PURPOSE: The overexpression of 15-hydroxyprostaglandin dehydrogenase (15-PGDH) has been proved to inhibit tumor growth and metastasis through degradation of prostaglandin E2 (PGE2), which is often overexpressed in various cancers and accelerates tumor progression. Cyclooxygenase-2 (COX-2), a synthase of PGE2, actively produces much PGE2 to counteract the 15-PGDH-induced antitumor efficacy. Here, ...

PURPOSE: Open partial nephrectomy (OPN) and robotic partial nephrectomy (RPN) are widely utilized techniques for small renal masses. The lack of tactile feedback and limitations of laparoscopy may result in differences in the surgical specimen that may impact oncologic outcome. We present postoperative pathological outcomes data in a cohort of ...

A dichotomy in the reactivity of B-H bonds is reported. A bis(N-heterocyclic carbene)-ligated iridium(iii) complex can effect rapid deuteration of boronate esters at room temperature with low catalyst loadings; however, borane and 9-BBN both undergo deuteration in the absence of catalyst, and do not react with the iridium complexes. This ...

In order to predict which ecosystem functions are most at risk from biodiversity loss, meta-analyses have generalised results from biodiversity experiments over different sites and ecosystem types. In contrast, comparing the strength of biodiversity effects across a large number of ecosystem processes measured in a single experiment permits more direct ...

Chronic granulomatous disease is a rare immunodeficiency due to defects in the phagocyte NADPH oxidase. The X-linked form (gp91 (phox) deficiency) accounts for about 70 % of cases; autosomal recessive p47 (phox) deficiency accounts for about 25 % of cases. We identified a 10 % incidence of diabetes in p47 ...

A retro-odontoid pseudotumor is usually a reactive fibrocartilaginous mass associated with atlantoaxial subluxation (AAS). However, a retro-odontoid pseudotumor not associated with AAS, which undergoes spontaneous regression following C1 laminoplasty, has been reported. The purpose of this study was to report surgical outcomes of C1 laminectomy for retro-odontoid pseudotumor without AAS. ...

Pulmonary embolism is the number one cause of preventable death among hospitalized patients. Prescription of either low dose low molecular weight heparin, such as enoxaparin or dalteparin, or prescription of low dose fondaparinux can halve the rate of deep vein thrombosis or pulmonary embolism, without increasing major bleeding complications. Nevertheless, ...

Insulin resistance (IR) is a key pathological feature of metabolic syndrome and subsequently causes serious health problems with an increased risk of several common metabolic disorders. IR related metabolic disturbance is not restricted to carbohydrates but impacts global metabolic network. Branched-chain amino acids (BCAAs), namely valine, leucine and isoleucine, are ...
