BACKGROUND: Walking speed is an important measure of gait impairment in multiple sclerosis (MS). The clinical assessment of walking speed requires dedicated time, space, and personnel, and may not accurately gauge real-world performance. The term "Ambient Measurement System" (AMS) refers to a new class of device that passively measures walking speed at home, without the need for dedicated space or specialized setup. This study compared an AMS, Echo5D, versus in-clinic standard measures of walking speed on a straight path...

During female meiosis, only one of four meiotic products is retained in the egg. It was previously proposed that chromosomes might compete for inclusion in the egg via their centromere 'strength'. Recent findings have revealed the primary requirements for such 'centromere drive'. First, CDC42 signaling from the oocyte cortex renders the meiotic I spindle asymmetric. Second, 'stronger' centromeres preferentially detach from microtubules in cortical proximity, making them more likely to orient away from the cortex, and be included in the egg...

Construction workers have the highest smoking rate among all occupations (39%). Hispanic/Latino workers constitute a large and increasing group in the US construction industry (over 2.6 million; 23% of all workers). These minority workers have lower cessation rates compared to other groups due to their limited access to cessation services, and lack of smoking cessation interventions adapted to their culture and work/life circumstances. Formative research was conducted to create an intervention targeting Hispanic/Latino construction workers...

Obesity prevalence is higher in rural compared to urban residents. Rural health clinics offer a potential venue for delivery of weight management. However, traditional programs require travel to attend on-site meetings which is impractical or inconvenient for rural residents. Clinic staff in most rural settings are unlikely to be trained to provide effective weight management. Remote delivery using group phone conferences (GP) or individual phone calls (IP), by staff associated with rural clinics eliminates the need for travel to attend on-site meetings...

Tumor cells recruit vascular endothelial cells and circulating endothelial progenitor cells to form new vessels to support their own growth and metastasis. VEGF, PDGF-BB and FGF-2 are three major pro-angiogenic factors and applied to promote angiogenesis. In this research, we demonstrated that anlotinib, a potent multi-tyrosine kinases inhibitor (TKI), showed a significant inhibitory effect on VEGF/PDGF-BB/FGF-2-induced angiogenesis in vitro and in vivo. Wound healing assay, chamber directional migration assay and tube formation assay indicated that anlotinib inhibited VEGF/PDGF-BB/FGF-2-induced cell migration and formation of capillary-like tubes in endothelial cells...

BACKGROUND: Selenium, an essential trace element, is incorporated into selenoproteins with a wide range of health effects. Selenoproteins may reach repletion at a plasma selenium concentration of ~125µg/L, at which point the concentration of selenoprotein P reaches a plateau; whether sustained concentrations higher than this are beneficial, or indeed detrimental, is unknown. OBJECTIVE: In a population of relatively low selenium status, we aimed to determine the effect on mortality of long-term selenium supplementation at different dose levels...

In E. coli chemosensory arrays, transmembrane receptors, a histidine autokinase CheA, and a scaffolding protein CheW interact to form an extended hexagonal lattice of signaling complexes. One interaction, previously assigned a crucial signaling role, occurs between chemoreceptors and the CheW-binding P5 domain of CheA. Structural studies showed a receptor helix fitting into a hydrophobic cleft at the boundary between P5 subdomains. Our work aimed to elucidate the in vivo roles of the receptor-P5 interface, employing as a model the interaction between E...

The immune system and the kidneys are closely linked. In health the kidneys contribute to immune homeostasis, while components of the immune system mediate many acute forms of renal disease and play a central role in progression of chronic kidney disease. A dysregulated immune system can have either direct or indirect renal effects. Direct immune-mediated kidney diseases are usually a consequence of autoantibodies directed against a constituent renal antigen, such as collagen IV in anti-glomerular basement membrane disease...

The ASHH2 CW domain is responsible for recognizing the methylation state at lysine 4 of histone 3 N-terminal tails and implicated in the recruitment of the ASHH2 methyltransferase enzyme correctly to the histones. The ASHH2 CW domain binds H3 lysine motifs that can be either mono-, di-, or tri-methylated [ARTK(meX)QTAR, where X denotes the number of methylations], but binds strongest to monomethylated instances (K d values reported in the range of 1 µm to 500 nM). Hoppmann et al. published the uncomplexed NMR structure of an ASHH2 CW domain in 2011...

Our earlier studies reported a unique potentiated combination (TriCurin) of curcumin (C) with two other polyphenols. The TriCurin-associated C displays an IC50 in the low micromolar range for cultured HPV+ TC-1 cells. In contrast, because of rapid degradation in vivo, the TriCurin-associated C reaches only low nano-molar concentrations in the plasma, which are sub-lethal to tumor cells. Yet, injected TriCurin causes a dramatic suppression of tumors in TC-1 cell-implanted mice (TC-1 mice) and xenografts of Head and Neck Squamous Cell Carcinoma (HNSCC) cells in nude/nude mice...
