Evidence of measurement precision, annual changes and monitoring time interval is essential when designing and interpreting longitudinal studies. Despite the precise measures, small annual changes in bone properties led to monitoring time intervals (MTIs) of 2-6 years in peripheral quantitative computed tomography (pQCT)-derived radial and tibial bone area, density, and estimated ...

Some species of the genus Characidium have heteromorphic ZZ/ZW sex chromosomes with a totally heterochromatic W chromosome. Methods for chromosome microdissection associated with chromosome painting have become important tools for cytogenetic studies in Neotropical fish. In Characidium cf. fasciatum, the Z chromosome contains a pericentromeric heterochromatin block, whereas the W ...

Gout is a prototype crystal-induced inflammatory disorder, characterized by neutrophil infiltration into inflamed joints. The identification of the role of NLRP3 inflammasome in the recognition of monosodium urate crystals and the subsequent release of IL-1β was a milestone in the elucidation of the pathogenesis of this disorder. IL-1β signaling is ...

Background. Although heterozygous filaggrin gene (FLG) mutation carriers seem to have an increased risk of atopic, irritant and allergic nickel dermatitis, it remains unclear whether the risk of contact sensitization to allergens other than nickel is also elevated in FLG mutation carriers. Objectives. We hypothesized that heterozygous FLG mutation carriers ...

Oligoribonucleotides are potentially capable of Darwinian evolution - they may replicate and can express an independent chemical phenotype, as embodied in modern enzymatic cofactors. Using quantitative chemical kinetics on a sporadically fed ribonucleotide pool, unreliable supplies of unstable activated ribonucleotides A and B at low concentrations recurrently yield a replicating ...

Hypertension complicates most cases of chronic kidney disease. While the prevalence and severity of hypertension increase as glomerular filtration rate falls, hypertension is often observed in patients with structural kidney disease while renal function is normal, in particular those with polycystic kidney disease or proteinuric glomerular diseases. On the other ...

Seasonal weight loss (SWL) is the most pressing constraint in ruminant production systems in tropical climates. SWL is controlled using supplementation, which is costly and difficult to implement in extensive systems, or using breeds adapted to tropical hot dry climates, like the Damara and Dorper. Albeit 15 years in Australia, little ...

We previously showed that (5S)-5-hydroxy-7-(4-hydroxyphenyl)-1-phenylhept-3-one (AO-0011) and (5S)-5-methoxy-1,7-diphenylhept-3-one (AO-0016) isolated from Alpinia officinarum exhibited stronger anti-influenza virus activity and anti-respiratory syncytial virus (RSV) activity, respectively, than the other isolated diarylheptanoids. In this study, we synthesized an enantiomer (AO-0503) and racemate (AO-0504) of AO-0011 and an enantiomer (AO-0514) of AO-0016. The ...

BACKGROUND: Short chain fatty acids (SCFA) are absorbed by carrier mediated uptake in the small intestine by pH-dependent SCFA/HCO(3) (-) exchangers on the apical membrane of epithelial cells. Conventional assumption is that MCT1 mediates SCFA/HCO(3) (-) exchange in the intestine. Further, due to the presence of multiple such anion exchangers, ...

The current imbalance in the biogeochemical cycle of nitrogen is as serious as that of carbon. One way to mitigate this problem is through the electrochemical reduction of nitrates under mild conditions, which is an appealing though not fully understood process. Therefore, deeper insight into the electrocatalytic reaction mechanism is ...

Those who are less skilled tend to overestimate their abilities more than do those who are more skilled-the so-called Dunning-Kruger effect. Less-skilled performers presumably have less of the knowledge needed to make informed guesses about their relative performance. If so, the Dunning-Kruger effect should vanish when participants do have access ...
