As a basic indicator of verbal ability, verbal fluency refers to the degree of fluency in the use of language to convey information. The different components of working memory play an important role in verbal fluency. The inhibiting control mechanism takes place during L2 production processing in bilinguals, which may affect their verbal fluency and distinguish them from native speakers. The participants of our study were 90 Tibetan-Chinese bilinguals and 30 native Chinese speakers. The study attempts to investigate the verbal fluency and cognitive mechanism of bilinguals' L2. The present study's results found L2 verbal fluency in Tibetan-Chinese bilinguals is significantly lower than that of native Chinese speakers. L2 verbal fluency has changed under the influence of their mother tongue, mainly manifested as its semantic fluency of L2 relying not only on the visuospatial sketchpad but also the phonological loop. Moreover, the processing of bilinguals' L2 is influenced by the processing mode of L1 in the verbal fluency task.

We summarize recent evidence on the shared genetics within and outside the musculoskeletal system (mostly related to bone density and osteoporosis).

Osteoporosis is determined by an interplay between multiple genetic and environmental factors. Significant progress has been made regarding its genetic background revealing a number of robustly validated loci and respective pathways. However, pleiotropic factors affecting bone and other tissues are not well understood. The analytical methods proposed to test for potential associations between genetic variants and multiple phenotypes can be applied to bone-related data. Compound Library high throughput A number of recent genetic studies have shown evidence of pleiotropy between bone density and other different phenotypes (traits, conditions, or diseases), within and outside the musculoskeletal system. Power benefits of combining correlated phenotypes, as well as unbiased discovery, make these studies promising. Studies in humans are supported by evidence from animal models. Drug development arug development and repurposing should benefit from the pleiotropic approach. We believe that future studies should take into account shared genetics between the bone and related traits.Oxidative stress is generated in biological system by several endogenous/exogenous factors like environmental-pollution/toxicity/diseases and by daily-life-stress. We previously showed that oxidative-stress impaired the activities/expressions of phase-II drug-metabolizing enzyme, sulfotransferases (SULTs). The SULT catalyzes sulfation of endogenous/exogenous compounds. Vitamin E is globally consumed by a large number of individuals for the cellular protection from oxidative stress and aging. Here, vitamin E (tocopherol; α/γ and tocotrienol; α/γ; 0, 1, 10, or 100 μM) was tested in human carcinoma cell line, HepG2 for their influences on SULTs expression/(western blotting). The effects of oxidant (glutathione-oxidized/GSSG) or reductant (glutathione-reduced/GSH, Dithiothreitol/DTT) on SULT activities were studied in rat-liver/human intestinal tissues. Results suggest, tocopherol is more inductive to monoamine-SULT (MPST) and Dehydroepiandrosterone-SULT (DHEAST) compared to that of tocotrienol (inconsistent change in PPST, phenol sulfotransferase/MPST/EST, estrogen sulfotransferase). The nuclear-factor constitutive androstane receptor (CAR) was found to be induced moderately. This study overall describes that vitamin E moderately influences SULTs expression. The induction ability of tocopherol should be judged taking into account its long-term consummation. Oxidative stress activates rat and human SULTs activities and expressions. Further studies are necessary in this regard.Triheptanoin (Dojolvi™), a synthetic medium-chain triglyceride, is being developed by Ultragenyx Pharmaceutical as a pharmaceutical-grade anaplerotic compound for use in the treatment of inherited metabolic disorders. In June 2020, triheptanoin received its first regulatory approval, in the USA, for use as a source of calories and fatty acids for the treatment of pediatric and adult patients with molecularly confirmed long-chain fatty acid oxidation disorders (LC-FAOD). Triheptanoin has also been investigated for use as a treatment in a range of other metabolic disorders or other diseases where energy deficiency is implicated. This article summarizes the milestones in the development of triheptanoin leading to this first regulatory approval for use in the treatment of pediatric and adult patients with LC-FAOD.The membrane-proximal external region (MPER) of Lassa virus (LASV) glycoprotein complex (GPC) is critical in modulating its functionality. Till now, the high-resolution structure of the intact GPC, including MPER is not available. In this study, we used alanine substitution to scan all 16 residues located in LASV MPER. Western blotting and quantification fusion assay showed that the residues located at the C terminus of the HR2 (M414 and L415) and N terminus of the MPER (K417 and Y419) are critical for GPC-mediated membrane fusion function. Furthermore, cell surface biotinylation experiments revealed that M414A, K417A and Y419A expressed similar levels as WT, whereas L415A mutant led to a reduction of mature GPC on the cell surface. Moreover, substitution of these residues with the similar residue such as M414L, L415I, K417R and Y419F would partly compensate the loss of the fusion activity caused by the alanine mutant in these sites. Results from this study showed that several key residues in the MPER region are indispensable to promote the conformational changes that drive fusion events and shed light on the structure analysis of LASV GPC and anti-LASV therapeutics.β-Globin gene transfer has been used as a paradigm for hematopoietic stem cell (HSC) gene therapy, but is subject to major difficulties, such as the lack of selection of genetically corrected HSCs, the need for high-level expression of the therapeutic gene, and cell-specific transgene expression. It took more than 40 years for scientists and physicians to advance from the cloning of globin gene and discovering globin gene mutations to improving our understanding of the pathophysiological mechanisms involved, the detection of genetic modifiers, the development of animal models and gene transfer vectors, comprehensive animal testing, and demonstrations of phenotypic improvement in clinical trials, culminating in the authorization of the first gene therapy product for β-thalassemia in 2019. Research has focused mostly on the development of lentiviral gene therapy vectors expressing variants of the β-globin gene or, more recently, targeting a γ-globin repressor, some of which have entered clinical testing and should soon diversify the available treatments and promote price competition.
