Frailty is a significant public health and clinical issue among the elder population. This study aimed to evaluate the nutritional status and renal function in relation to frailty among elderly Taiwanese.

We administered community-based health surveys to the elder population in Chiayi County, Taiwan, from 2017 to 2019.

We measured nutritional status (including serum albumin and total protein levels), renal function (including serum blood urea nitrogen, creatinine, urine protein, and urine creatinine levels), hand grip strength (GS) and calculated appendicular muscle mass (AMM).

The study recruited 3739 participants (2139 women). Participants of both sexes with normal GS had higher serum albumin levels and lower urine protein/creatinine ratios (UPCRs). For the men with normal and weak GS, serum albumin levels were 4.15 ± 0.2 and 4.10 ± 0.2 g/dL (p < 0.01), and UPCRs were 123.1 ± 219.6 and 188.7 ± 366.2 (p < 0.001), respectively. GS was positively correlated with serum albumin and urine creatinine levels (r = 0.136 and 0.177, both p < 0.001). AMM was also positively correlated with serum albumin and urine creatinine levels (r = 0.078 and 0.091, both p < 0.001). In the multivariate regression model, for every 1 g/dL increase in serum albumin level, there was a 1.9 and 1.7-kg increase in GS for men and women (p < 0.05 and p < 0.01), respectively. The final model for predicting GS included age, albumin, BUN, and UPCR (urine creatinine for women) which presented a variance of 22.1% and 13.8%, respectively.

Proper dietary nutritional intake and maintaining renal function are key elements for preventing frailty among elder population in Taiwan.

Geometric morphometric analyses allow re-evaluation of both size and shape variation of skeletal elements, and more meaningful comparisons of sexual dimorphism of different ancestry groups. Additionally, it has shown that some postcranial bones may be more useful for ancestry estimation than previously thought. Geometric morphometric analysis was performed on the radii of 1049 South African individuals (417 females, 578 males) of the country's three largest ancestry groups to assess morphological variation according to sex and ancestry. this website Three-dimensional landmark datasets of radii were superimposed and scaled to a common centroid size using Generalized Procrustes Analysis. Mean centroid sizes of groups were compared using parametric statistics. Morphological variation was assessed using Discriminant Function Analysis, coupled with leave-one-out cross-validation to assess accuracies this variation, even when sex and ancestry are simultaneously considered. The greater ancestry variation allows for relatively good accuracies in estimation, even for highly heterogeneous South African groups that are subject to significant genetic and environmental influences.Burial 280 is a 31- to 40-year-old male Native American individual who lived in a 10th to 16th century coastal foraging society in California. His remains display a large ectocranial elevation on the occipital, measuring 23.3 mm anteroposteriorly, 25.3 mm mediolaterally, and is elevated to 20.1 mm. It is located along the superior nuchal line on the left side of the occipital and represents an extremely rare occipital localization of a particular type of trauma-related osteoma. In our prior study of Burial 280, trauma etiology was not considered; herein, we present evidence for such a cause. Such trauma-related neoplasms are sometimes called ballooned (or giant, depending on size) osteomas. The presence of this tumor appears to have resulted in asymmetrical cranial muscle use and consequent skeletal changes. This case study illustrates that cranial trauma may sometimes induce benign tumor elevations, rather than a depression or pronounced fracture.Specialized pro-resolving lipid mediators (SPMs) are natural bioactive agents actively involved in inflammation resolution. SPMs act when uncontrolled inflammatory processes are developed, for instance, in patients of COVID-19 or other diseases. The so-called resolution pharmacology aims at developing new treatments based on the use of SPMs as agonists, which promote inflammation resolution without unwanted side effects. It has been shown that the biosynthesis of SPMs called eicosapentaenoic acid (EPA)-derived E-series resolvins is initiated by aspirin-acetylated COX-2 from EPA, leading to 18-hydroperoxy-eicosapentaenoic acid (18-HpEPE). However, there are many open questions concerning the intriguing role of aspirin in the molecular mechanism of resolvin formation. Our MD simulations, combined with QM/MM calculations, show that the potential energy barriers for the H16-abstraction from EPA, required for forming 18-HpEPE, are higher than for the H13-abstraction, thus explaining why 18-HpEPE is a marginal product of COX-2 catalysis. By contrast, in the aspirin-acetylated COX-2/EPA complex, the H16proS-abstraction energy barriers are somewhat lower than the H13proS energy barriers and much smaller than the H16-transfer barriers in the wild type COX-2/EPA system. Those results agree with the experimental observation that aspirin favours the synthesis of several SPMs known as aspirin-triggered resolvins. In the following step of the catalytic mechanism, the calculated O2 addition to C18 is preferred versus the addition to C14 which also agrees with 18R-HEPE and 18S-HEPE being the main products from EPA in aspirin-acetylated COX-2.The search for new materials, with ideal electronic and magnetic properties for potential applications in nanoelectronics, has been extremely successful so far, and has paved the way for us to reimagine all technological devices. In the present work, we study the design of MgCl2 nanoribbons for applications in nanoelectronics and spintronics, by employing first-principles calculations based on density functional theory (DFT) and non-equilibrium Greens function techniques. Our results show that the properties of MgCl2 nanoribbons depend strongly not only on their geometrical form (armchair or zigzag) but also on the atoms at their edges. The armchair MgCl2 nanoribbon is a semiconductor and the zigzag nanoribbons vary from semiconducting, to metallic, to ferromagnetic, and to half-metallic, depending on the edge terminations. All these nanoribbons are very stable, with a relatively low cohesive energy per atom, and their attributes are not affected by the width of the nanoribbon. From transport calculations, we observed partial spin filtering in the ferromagnetic nanoribbon and perfect spin filtering in the two half-metallic nanoribbons. Moreover, we show how the current versus voltage curves can be fully understood by analysing the alignment of the energy levels of the electrodes. Our results corroborate the promising use of single-layer MgCl2 for the development of spintronics devices.A vinylogy concept driven annulation strategy is developed to access [4,4]-carbospirocycles from alkylidene malononitriles and cyclopentene-1,3-diones. The reaction is catalyzed by an inexpensive organocatalyst and products with three stereocenters were obtained as a single diastereomer in high yields. The spiro-selectivity originates from the reaction of the thermodynamic enolate intermediate which is fundamentally intriguing.In this work we present a new multi-resonance thermally activated delayed fluorescence (MR-TADF) emitter paradigm, demonstrating that the structure need not require the presence of acceptor atoms. Based on an in silico design, the compound DiICzMes4 possesses a red-shifted emission, enhanced photoluminescence quantum yield, and smaller singlet-triplet energy gap, ΔEST, than the parent indolocarbazole that induces MR-TADF properties. Coupled cluster calculations accurately predict the magnitude of the ΔEST when the optimized singlet and triplet geometries are used. Slow yet optically detectable reverse intersystem crossing contributes to low efficiency in organic light-emitting diodes using DiICzMes4 as the emitter. However, when used as a terminal emitter in combination with a TADF assistant dopant within a hyperfluorescence device architecture, maximum external quantum efficiencies of up to 16.5% were achieved at CIE (0.15, 0.11). This represents one of the bluest hyperfluorescent devices reported to date. Simultaneously, recognising that MR-TADF emitters do not require acceptor atoms reveals an unexplored frontier in materials design, where yet greater performance may yet be discovered.Covering up to August 2021Lysobacter is a genus of Gram-negative bacteria that was classified in 1987. Several Lysobacter species are emerging as new biocontrol agents for crop protection in agriculture. Lysobacter are prolific producers of new bioactive natural products that are largely underexplored. So far, several classes of structurally interesting and biologically active natural products have been isolated from Lysobacter. This article reviews the progress in Lysobacter natural product research over the past ten years, including molecular mechanisms for biosynthesis, regulation and mode of action, genome mining of cryptic biosynthetic gene clusters, and metabolic engineering using synthetic biology tools.Photocatalytic nitrogen fixation is a promising approach owing to its environmental friendliness and cost-effectiveness. The 2D/2D BiVO4/rGO hybrid developed in this study exhibits a high nitrate-production rate of 1.45 mg h-1 g-1 and an apparent quantum efficiency (QE) of 0.64% at 420 nm, which represents one of the most highly active photocatalysts reported thus far.New strategies are needed to predict and overcome metastatic progression and therapy resistance in prostate cancer. One potential clinical target is the stem cell transcription factor SOX2, which has a critical role in prostate development and cancer. We thus investigated the impact of SOX2 expression on patient outcomes and its function within prostate cancer cells. Analyses of SOX2 expression among a case-control cohort of 1028 annotated tumor specimens demonstrated that SOX2 expression confers a more rapid time to metastasis and decreased patient survival after biochemical recurrence. SOX2 ChIP-Seq analyses revealed SOX2-binding sites within prostate cancer cells which differ significantly from canonical embryonic SOX2 gene targets, and prostate-specific SOX2 gene targets are associated with multiple oncogenic pathways. Interestingly, phenotypic and gene expression analyses after CRISPR-mediated deletion of SOX2 in castration-resistant prostate cancer cells, as well as ectopic SOX2 expression in androgen-stance. Further, our data suggest clinical opportunities to exploit SOX2 as a biomarker for staging and imaging, as well as a potential pharmacologic target.
A number of genes have been identified in which rare variants can cause obesity. Here we analyse a sample of exome sequenced subjects from UK Biobank using BMI as a phenotype with the aims of identifying genes in which rare, functional variants influence BMI and characterising the effects of different categories of variant.

There were 199,807 exome sequenced subjects for whom BMI was recorded. Weighted burden analysis of rare, functional variants was carried out, incorporating population principal components and sex as covariates. For selected genes, additional analyses were carried out to clarify the contribution of different categories of variant. Statistical significance was summarised as the signed log 10 of the p value (SLP), given a positive sign if the weighted burden score was positively correlated with BMI.

Two genes were exome-wide significant, MC4R (SLP = 15.79) and PCSK1 (SLP = 6.61). In MC4R, disruptive variants were associated with an increase in BMI of 2.72 units and probably damaging nonsynonymous variants with an increase of 2.
