BACKGROUND The efficacy of antihypertensive (AH) treatment after stroke has been investigated in several randomized clinical trials. However, non-adherence to AH medication is common for stroke patients in "real world" setting. The purpose of this study was to assess the impact of persistence with AH agents on ischemic stroke (IS) outcomes. METHODS AND RESULTS Using the China National Stroke ...

The lectin actinohivin (AH) is a monomeric carbohydrate-binding agent (CBA) with three carbohydrate-binding sites. AH strongly interacts with gp120 derived from different X4 and R5 human immunodeficiency virus (HIV) strains, simian immunodeficiency virus (SIV) gp130, and HIV type 1 (HIV-1) gp41 with affinity constants (KD) in the lower nM range. The gp120 and gp41 binding of AH is selectively r...

Pyrolysis products of proteins and amino acids are highly mutagenic, but metabolism of these chemicals by rat liver subcellular fractions is known to be required for production of the mutagenic intermediates. We examined the mutagenesis of seven purified pyrolysis products from tryptophan, lysine, glutamic acid, and soybean globulin with Salmonella typhimurium strain TA98 in the presence of liv...

Hepatocytes and Kupffer cells in primary culture both secrete plasma-type platelet-activating factor-acetylhydrolase (pPAF-AH) into serum-free culture medium. The rate of secretion of pPAF-AH by Kupffer cells was 20 to 25 times higher than from hepatocytes, and Kupffer cells expressed a higher level of pPAF-AH mRNA than did hepatocytes. Purified liver cell-secreted pPAF-AH exhibited a major pro...

Aqueous humor (AH) is a transparent fluid which fills the anterior and posterior chambers of the eye. It supplies nutrients and removes metabolic waste from avascular tissues in the eye. Proper homeostasis of AH is required to maintain adequate intraocular pressure as well as optical and refractive properties of the eye. Application of metabolomics to study human AH may improve knowledge about ...

OBJECTIVE Abnormal activations of neural networks implicated in auditory stimuli processing are hypothesized to generate auditory hallucinations (AH) in schizophrenia spectrum disorders. Because repetitive transcranial magnetic stimulation (rTMS) has the potential to modulate neural network activity, several studies have explored its use in treating medication-resistant AH, with mixed results i...

BACKGROUND arterial hypertension (AH) is a health problem that affects a large number of undiagnosed or inadequately treated hypertensive individuals and presents a high rate of treatment nonadherence. OBJECTIVE to estimate the prevalence of AH and its correlation with some cardiovascular risk factors among the adult population of the town of Firminopolis, state of Goiás, Brazil. METHODS de...

BACKGROUND Platelet-activating factor (PAF) is a proinflammatory phospholipid mediator involved in the pathogenesis of glomerulonephritis (GN). In plasma, PAF is hydrolyzed and inactivated by PAF-acetylhydrolase (PAF-AH), an enzyme associated with lipoproteins, mainly with the low-density lipoprotein. PAF-AH activity has been found in urine of patients with primary GN, however the source and ty...

PURPOSE Primary open angle glaucoma (POAG) is a leading cause of irreversible blindness on a global level. Researchers have yet to specify the exact mechanisms of POAG; the respective relationships between POAG and elevated intraocular pressure (IOP), as well as optic neuropathy, remain particularly unclear. It is known, however, that the expression profile for some proteins in the aqueous humo...

We aimed to develop an alginate hydrogel (AH) modified with nano-/microfibers of titanium dioxide (nfTD) and hydroxyapatite (nfHY) and evaluated its biological and chemical properties. Nano-/microfibers of nfTD and nfHY were combined with AH, and its chemical properties were evaluated by FTIR spectroscopy, X-ray diffraction, energy dispersive X-Ray analysis, and the cytocompatibility by the WST...
