The diagnosis of human immunodeficiency virus (HIV)-associated neurocognitive impairment is time-intensive and often omitted in busy outpatient settings. Brief screening tools are needed. The Montreal Cognitive Assessment (MoCA) and the Alzheimer's disease (AD)-8 have been used in neurodegenerative disorders. We evaluated the sensitivity and specificity of these brief screening tools ...

Surface initiated atom transfer radical polymerization (ATRP) was triggered after diffusion of a CuI/L activator generated at a working electrode. A stable [CuIIL]/[CuIL] ratio gradient was formed at the gap between the working electrode and initiator terminated substrate due to ion diffusion. The size of the gap can be used ...

Lysosome-associated protein transmembrane-4 beta (LAPTM4B) is a novel cancer-related gene. It has two alleles designated LAPTM4B*1 and LAPTM4B*2.

Acute spectral responses to H(2)PO(4)(-) in HEPES buffer (DMSO-HEPES 1 : 9) have been observed. The selectivity zone in terms of pH of the ...

Abstract Membrane proteins control fundamental processes that are inherent to nearly all forms of life such as transport of molecules, catalysis, signaling, vesicle fusion, sensing of chemical and physical stimuli from the environment, and cell-cell interactions. Membrane proteins are harbored within a non-equilibrium fluid-like environment of biological membranes that separate ...

A regioselective [3 + 2] cycloaddition of benzofuranone type active olefins with allenoates catalyzed by trivalent phosphines has been developed, which provided an easy access to enriched functionalized spirocyclic benzofuranones. The reactions accommodated a number of benzofuranone type electron-deficient olefins and allenoates to give the desired 3-spirocyclopentane benzofuran-2-ones or 2-spirocyclopentane ...

While radical nephroureterectomy represents the gold standard for managing upper-tract urothelial carcinoma, nephron-sparing approaches have increasingly been utilized in the elective setting. Such considerations are accentuated by contemporary studies highlighting sequelae related to chronic kidney disease following nephrectomy. Kidney sparing treatments including segmental ureteral resection and endoscopic ablation may therefore ...

Anti-proteinase 3 anti-neutrophil cytoplasmic antibodies (anti-PR3 ANCA) represent an established serologic marker of active granulomatosis with polyangiitis, but their role as a serologic marker in inflammatory bowel disease (IBD) remains uncertain. This study evaluates the presence of anti-PR3 ANCA and their validity as a serologic marker to aid in the ...

Desquamation or cell shedding in mammalian skin is known to involve serine proteases, aspartic proteases and glycosidases. In addition, evidence continues to accumulate that papain-like cysteine proteases and an inhibitor cystatin M/E largely confined to the cutaneous epithelia also play key roles in the process. This involves the complete proteolysis ...

Adrenal abnormalities are commonly identified on computed tomography (CT) and are seen in at least 5 % of CT examinations of the thorax and abdomen.
