Resistance to non-nucleoside reverse transcriptase inhibitors (NNRTIs) is a leading cause of HIV treatment failure. Often included in antiviral therapy, NNRTIs are chemically diverse compounds that bind an allosteric pocket of enzyme target reverse transcriptase (RT). Several new NNRTIs incorporate flexibility in order to compensate for lost interactions with amino acid conferring mutations in RT. Unfortunately, even successful inhibitors such as diarylpyrimidine (DAPY) inhibitor rilpivirine are affected by mutations in RT that confer resistance...

In longitudinal studies, standard analysis may yield biased estimates of exposure effect in the presence of time-varying confounders that are also intermediate variables. We aimed to quantify the relationship between obesity and coronary heart disease (CHD) by appropriately adjusting for time-varying confounders. This study performed on a subset of the Atherosclerosis Risk in Communities Study (1987-2010). General obesity defined as body mass index ≥30 kg/m2, abdominal obesity (AOB) defined as waist circumference ≥102 cm in men and ≥88 cm in women, and waist to hip ratio categorized at ≥0...

OBJECTIVES: Multiple sclerosis (MS) is a demyelinating disorder with a complex autoimmune pathophysiology. Its initiation and progression correlate with IL-17 and the related transcription factor, RORγt. All-trans retinoic acid (ATRA) is a bioactive derivative of vitamin A, and docosahexaenoic acid (DHA) is an active metabolite of omega-3 fatty acid; both have immunomodulatory effects in many immune disorders. This study investigated the effects of DHA and ATRA individually and in combination on IL-17 and RORγt gene expression in peripheral blood mononuclear cells (PBMCs) of relapsing-remitting MS (RRMS) patients who were receiving interferon beta (IFN-β)...

Sesquiterpene lactones have long been used in traditional Chinese medicines to treat inflammatory diseases. Recently, sesquiterpene lactone family compounds have been recognized as potential anticancer agents. Thus, it is necessary to explore new sesquiterpene lactones and their antitumor mechanism for cancer treatments. In the present study, we have explored the potential anti-cancer activity of a novel sesquiterpene lactone compound "santamarine" (STM) in HepG2 cells. It inhibited proliferation and induced apoptosis dose-dependently with IC50 ~ 70 μM...

Regenerative medicine is a translational field which combines tissue engineering and molecular biology to construct spare organs or help injured or defective tissues to regenerate or restore their normal functions. This is particularly important with specific organs such as heart, central nervous system, retina or limbs which possess very limited regenerative capacity. As such, regenerative medicine has received peculiar attention in the last decade. In this regard, Wnt/β-catenin signaling pathway has been subject to intensive research, since it plays many essential roles in the regulation of the progenitor cell fate, developmental decisions, proliferation during embryonic development, and adult tissue homeostasis...

AIMS: Functional heterogeneity of HDL is attributed to its diverse bioactive components. We evaluated whether vasodilatory effects of HDL differed across HDL subpopulations, reflecting their distinct molecular composition. METHODS: Capacity of five major HDL subfractions to counteract inhibitory effects of oxidized low-density lipoprotein on acetylcholine-induced vasodilation was tested in a rabbit aortic rings model. Nitric oxide (NO) production, an essential pathway in endothelium-dependent vasorelaxation, was studied in SV40-transformed murine endothelial cells (SVEC)...

BACKGROUND: Sirtuins, including SIRT1 and SIRT2, are longevity-associated deacetylase enzymes that modulate metabolic homeostasis in response to the cellular energy state. Adenosine monophosphate activated protein kinase (AMPK) and SIRT1 are interrelated and share several common target pathways. This study aimed to evaluate the SIRT1 and SIRT2 gene expression in peripheral blood mononuclear cells (PBMCs) as well as plasma levels of AMPK, in obese children and adolescents. MATERIALS AND METHODS: Participants included 60 children and adolescents (30 obese and 30 age- and gender-matched control subjects)...

Aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor, connecting environmental stimulators with the immune system. M1 macrophages are a part of immune system that contribute to the inflammatory events in the pathogenesis of Behcet's disease (BD). The effect of AHR on the macrophages in BD patients is still unclear. In this study, we investigated the mRNA expression of AHR in the monocyte-derived and M1 macrophages in active BD patients in comparison to healthy controls. Isolated monocytes from 10 healthy controls and 10 active BD patients were differentiated to macrophages by macrophage-colony stimulating factor (M-CSF) for 7 days...

The synthesis and characterization of a series of donor-π-acceptor-π-donor (D-A-D) curcuminoid molecules are here presented incorporating π-extended aryl and electron-donating amino terminal functionalization. Computational evaluation shows these molecules possess quadrupolar character with the lowest energy transitions displaying high molar extinction coefficients with broad tunability through manipulation of terminal donating groups. Consistent with their quadrupolar nature, these molecules show varying degrees of solvatochromic behavior in both their absorption and emission spectra which has been analyzed by Lippert-Mataga and Kamlet-Taft analysis...

Congenitally corrected transposition of great arteries (CCTGA) is a rare anomaly described by atrioventricular and ventriculoarterial discordance. On the other hand, mesocardia that is extremely rare includes two relatively well-defined apexes defined by each ventricle with the major axis of the heart lies in the midline. We describe a rare case of an asymptomatic 20-year-old woman with mesocardia, CCTGA, and severe subvalvular pulmonic stenosis due to a ball-shaped accessory tissue in left ventricular outflow tract...
