Approximately 80% of female WT NOD mice spontaneously develop diabetes, whereas B cell deficient (B-/-) NOD mice are resistant to diabetes. B-/- mice are also resistant to other spontaneous and some experimentally induced autoimmune diseases, including arthritis, SLE, Sjogren's syndrome and thyroiditis. Under normal conditions, activation of self-reactive T cells ...

Purpose:To evaluate diagnostic performance of three nonenhanced methods: variable-refocusing-flip angle (FA) fast spin-echo (SE)-based magnetic resonance (MR) angiography (variable FA MR) and constant-refocusing-FA fast SE-based MR angiography (constant-FA MR) and flow-sensitive dephasing (FSD)-prepared steady-state free precession MR angiography (FSD MR) for calf arteries, with dual-injection three-station contrast material-enhanced MR angiography ...

Context:Ovarian hyperstimulation syndrome (OHSS) is a potentially life-threatening complication of assisted reproduction. OHSS is induced by an ovarian release of vasoactive, angiogenic substances that results in vascular hyperpermeability, leakage, and shift of fluids from blood vessels into the extravascular space with consequent ascites and edema that are attributed to vascular ...

Gap junctions mediate intercellular signalling in arteries and contribute to endothelium-dependent vasorelaxation, conducted vascular responses and vasomotion. Considering its putative role in vascular dysfunction, mechanistic insights regarding the control of gap junction conductivity are required. Here, we investigated the consequences of endothelial alkalinisation for gap junction communication and endothelium-dependent vasorelaxation ...

Exploiting advanced photocatalysts under visible light is of primary significance for the development of environmentally relevant photocatalytic decontamination processes.

Stenotrophomonas maltophilia is a multi-drug resistant organism increasingly isolated from the lungs of cystic fibrosis (CF) patients. One hundred twenty-five S. maltophilia isolates from 85 CF patients underwent planktonic and biofilm susceptibility testing against 9 different antibiotics, alone and in double antibiotics combinations. When S. maltophilia were grown as a ...

Phospholipase C beta 1 (PLCβ1) is a downstream effector of G-protein coupled receptor signalling and holds central roles in reproductive physiology. Mice with a disruption in the Plcβ1 gene are infertile with pleiotropic reproductive defects, the major reproductive block in females being implantation failure. Here, PLCβ1 was demonstrated at the ...

ABSTRACT: BACKGROUND: Increasing evidences have suggested that autoantibodies against muscarinic-2 acetylcholine receptor (anti-M2-R) may play an important role in the development of atrial fibrillation (AF). Predictive value of pre-procedural anti-M2-R for the recurrence of AF after radiofrequency catheter ablation is still unclear. METHODS: Totally 76 AF patients with preserved left ...

High temperature pyrolysis conversion of organic analytes to H2 in hydrogen isotope ratio compound-specific isotope analysis (CSIA) is unsuitable for chlorinated compounds such as trichloroethene (TCE) and cis-1,2-dichloroethene (DCE), due to competition from HCl formation. For this reason, the information potential of hydrogen isotope ratios of chlorinated ethenes remains untapped. ...

This longitudinal study examined early cognitive risk and protective factors for Grade 2 reading disability (RD). We first examined the reading outcome of 198 children in four developmental cognitive subgroups that were identified in our previous analysis: dysfluent trajectory, declining trajectory, unexpected trajectory and typical trajectory. We found that RD ...

Many risk factors have been identified as contributing to the development or persistence of low back pain (LBP). However, the juxtaposition of both high and low levels of physical activity being associated with LBP reflects the complexity of the relationship between a risk factor and LBP. Moreover, not everyone with ...

MicroRNAs (miRNAs) have emerged as novel post-transcriptional regulators of gene expression. These short non-coding RNAs are involved in diverse biological processes and their dysregulation is often observed under diseased conditions. Therefore, miRNAs hold great potential as clinical biomarkers of physiological and pathological states and extensive efforts are underway to develop ...

Olive breeding programmes are focused on selecting for traits as short juvenile period, plant architecture suited for mechanical harvest, or oil characteristics, including fatty acid composition, phenolic, and volatile compounds to suit new markets. Understanding the molecular basis of these characteristics and improving the efficiency of such breeding programmes require ...

Recent genome-wide computational screens that search for conservation of RNA secondary structure in whole genome alignments (WGAs) have predicted thousands of structural noncoding RNAs (ncRNAs). The sensitivity of such approaches, however, is limited due to their reliance on sequence-based whole-genome aligners, which regularly misalign structural ncRNAs. This suggests that many ...

Social insects exhibit remarkable variation in their colony breeding structures, both within and among species. Ecological factors are believed to be important in shaping reproductive traits of social insect colonies, yet there is little information linking specific environmental variables with differences in breeding structure. Subterranean termites (Rhinotermitidae) show exceptional variation ...

Priapism due to sickle cell disease is a common but less well characterized complication of the disorder. It represents a "medical emergency" with the key determinant of outcome being the duration of penile ischaemia and time to detumescence of <4 h associated with a successful treatment outcome. Management can be outpatient-based ...

Long-term depression (LTD) at parallel fiber synapses on a cerebellar Purkinje cell has been regarded as a cellular basis for motor learning. Although Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) has been implicated in the LTD induction as an important Ca(2+)-sensing molecule, the underlying signaling mechanism remains unclear. Here, we attempted to ...

During myogenesis, myoblasts fuse into multinucleated myotubes that acquire the contractile fibrils and accessory structures typical of striated skeletal muscle fibers. To support the high energy requirements of muscle contraction myogenesis entails an increase in mitochondrial (mt) mass with stimulation of mtDNA synthesis and consumption of DNA precursors (dNTPs). Myotubes ...
