An increased understanding is needed of the physiological effects and plausible biological mechanisms that link PM2.5 (particulate matter with an aerodynamic diameter below 2.5μm) exposure to mortality and morbidities such as atherosclerosis and respiratory disease. PM2.5 causes carcinogenic health effects. Biomonitoring in humans has suggested that 8-oxo-7, 8-dihydro-2-deoxyguanosine (8-oxodG) and N7-methylguanine (N7-MeG) are correlated with oxidative and methylated DNA damage. Thus, it is meaningful to explore the mechanisms of mutagenesis and carcinogenesis associated with oxidative and methylated DNA damage by simultaneously measuring these two markers...

In this study, we prepared photoluminescent l-cysteine (Cys)-capped gold nanoclusters (Cys-Au NCs) via NaBH4-mediated reduction of aggregated coordination polymers (supramolecules) of -[Cys-Au(i)]n-. The -[Cys-Au(i)]n- supramolecules with interesting chiral properties were formed through simple reactions of chloroauric acid (HAuCl4) with Cys at certain pH values (pH 3-7). The -[Cys-Au(i)]n- polymers could self-assemble into -[Cys-Au(i)]n- supramolecules with irregular morphologies and diameters larger than 500 nm through stacked hydrogen bonding and zwitterionic interactions between Cys ligands and through Au(i)Au(i) aurophilic interactions in solutions with pH values ≤7...

Browning white adipocytes may be a new target in anti-obesity therapy. Pentamethylquercetin (PMQ) has been shown to have anti-obesity effects in monosodium glutamate-induced obese mice. Here, we aimed to study the anti-obesity effects of PMQ in vitro and in vivo and to determine if adipose browning is involved in the mechanism underlying the anti-obesity effects of PMQ. We evaluated the effects of PMQ on cell proliferation, cell differentiation, glucose consumption, cellular lipid metabolism, and related brown gene expression in 3T3-L1 adipocytes...

BACKGROUND: Carbon monoxide (CO) poisoning may cause toxicity to the cardiovascular system. However, the association between CO poisoning and the risk of major adverse cardiovascular events (MACE) remains unestablished. We investigated the incidence of MACE after CO poisoning in Taiwan and evaluated whether CO-poisoned individuals had a higher risk of MACE than did the general population. METHODS: Using Taiwan's National Health Insurance Research Database (NHIRD) during 2005-2013, a nationwide population-based cohort study was conducted among patients who experienced CO poisoning between 2005 and 2013...

We have previously demonstrated that KMUP-1, a xanthine-based nitric oxide enhancer, attenuates diabetic glomerulosclerosis, while increasing renal endothelial nitric oxide synthase expression in rats. However, the anti‑fibrotic mechanisms of KMUP‑1 treatment in diabetic nephropathy in terms of cell biology and transforming growth factor-β1 (TGF‑β1) remain unclear. Therefore, the present study involved investigating the effects of KMUP‑1 on high glucose (HG) or TGF‑β1‑induced pro‑fibrotic proteins in mouse mesangial (MES13) cells, and the effects of KMUP‑1 on streptozotocin (STZ)‑induced diabetic rats...

Matrine, a Sophora alkaloid, exhibits antiproliferative and anti-carcinogenic activities through several mechanisms. In a previous study, we found that matrine could effectively inhibit the proliferation of castration-resistant prostate cancer (CRPC). In the present study, the effect of matrine and LY294002 on the expression of the Akt/FoxO3a signaling pathway was examined by western blot analyses and RT-PCR. We discovered that matrine significantly inhibited the proliferation of both prostate cancer cell line PC-3 and prostate epithelial cell line RWPE1, induced apoptosis and induced cell cycle arrest...

The endothelial expression of cell adhesion molecules plays a leading role in atherosclerosis. Lycopene, a carotenoid with 11 conjugated double bonds, has been shown to have anti-inflammatory properties. In the present study, we demonstrate a putative mechanism for the anti-inflammatory effects of lycopene. We demonstrate that lycopene inhibits the adhesion of tumor necrosis factor α (TNFα)-stimulated monocytes to endothelial cells and suppresses the expression of intercellular cell adhesion molecule-1 (ICAM-1) at the transcriptional level...

p-Bis(arylcarbonyl)pentiptycenes 2 (aryl = 4-(trifluoromethyl)phenyl) and 3 (aryl = mesityl) have been prepared and investigated as redox-gated molecular rotors. For 2, rotations about the pentiptycene-carbonyl bond (theαrotation) and about the aryl-carbonyl bond (the β rotation) are independent and the rotation barriers are 11.3 and 9.5 kcal mol-1, respectively, at 298 K. In contrast, the α and β rotations in 3 are correlated (geared) in a 2-fold cogwheel pathway between the aryl and the pentiptycene groups with a much lower rotation barrier of 6...
