Deposited road particles (DRPs) collected from 13 heavily traveled roadways in an urban area of Southern Lake Biwa, Japan, were analyzed for polycyclic aromatic hydrocarbons (PAHs) in seven different particle size fractions (< or = 20 to 1000-2000 microm) and evaluated for the aryl hydrocarbon receptor (AhR) ligand activity by using a yeast bioassay. The mean compositions of individual PAHs to total PAH concentrations in different particle size fractions were 19-21% for pyrene, which was the mos

Advanced malignant melanoma remains a challenging cancer. Over the past year, there have been 3 agents approved for treatment of melanoma by Food and Drug Administration. These include pegylated interferon alpha-2b for stage III melanoma, vemurafenib for unresectable or metastatic melanoma with BRAF V600E mutation, and ipilimumab for treatment of unresectable or metastatic melanoma. This review will also update on the development of novel agents, including tyrosine kinase inhibitors and adoptive

Obesity causes low-grade inflammation that results in dyslipidemia and insulin resistance. We evaluated the effect of puerarin on obesity and metabolic complications both in silico and in vivo and investigated the underlying immunological mechanisms. Twenty C57BL/6 mice were divided into four groups: normal chow, control (HFD), HFD + puerarin (PUE) 200 mg/kg, and HFD + atorvastatin (ATO) 10 mg/kg groups. We examined bodyweight, oral glucose tolerance test, serum insulin, oral fat tolerance test,

Insulin resistance is strongly associated with the metabolic syndrome, and chronic inflammation is known to be a major mechanism of insulin resistance and is a therapeutic target. This study was designed to evaluate the effect of <i>Scutellaria baicalensis</i> (SB) in high-fat diet (HFD)-induced insulin-resistant mice and to investigate its mechanism based on inflammatory responses. Mice were fed a HFD to induce insulin resistance and then administered SB for nine weeks. Body weight, glucose, li

Wearable activity trackers can motivate older adults to engage in the recommended daily amount of physical activity (PA). However, individuals may not maintain their use of the trackers over a longer period. To investigate the attitudes of activity tracker adoption and their effects on actual PA performance, we conducted a three-month study. We gave activity trackers to 16 older adults and assessed attitudes on activity tracker adoption through a survey during the study period. We extracted part

Obesity represents chronic low-grade inflammation that precipitates type 2 diabetes, cardiovascular disease, and cancer. Berberine (BBR) has been reported to exert anti-obesity and anti-inflammatory benefits. We aimed to demonstrate the underlying immune-modulating mechanisms of anti-obesity effects of BBR. First, we performed in silico study to identify therapeutic targets, describe potential pathways, and simulate BBR docking at M1 and M2 adipose tissue macrophages (ATMs), tumor necrosis facto

Interruption is a widespread phenomenon in human–computer interaction in modern working environments. To minimize the adverse impact or to maximize possible benefits of interruptions, a reliable approach to evaluate interruption cost needs to be established. In this paper, we suggest a new approach to evaluate the interruption cost by cognitive workload and task performance measures. The cognitive workload is assessed by pupil diameter changes and National Aeronautics and Space Administration (N

From the results in this study, we might suggest that Pro/Ala genotype in Taeeumin is associated with the susceptibility to ischemic stroke. To the author's best knowledge, this is the first report to study on genetic level the potential relationship between ischemic stroke and Sasang constitutional medicine, one of traditional Korean medicines (TKM). Authors hope that this study could provide a new approach for the study of ischemic stroke and merit further research.

From these results, baicalin can be a promising treatment option for obesity and its related metabolic diseases based on its anti-inflammatory property.
