Metformin, an antidiabetic drug, is well known for its multifarious properties and its ability to modulate inflammatory cascade. Ulcerative colitis (UC) is an inflammatory condition of the colon where drugs exhibiting anti-inflammatory property have been shown to induce and maintain remission. The objective of the present study was to evaluate the efficacy of metformin against acetic-acid induced colitis in rat. The study included five groups of rats namely normal control, experimental control, drug treated groups (50 and 500mg/kg of metformin, MET50, MET500 and 300mg/kg of mesalazine, MSZ300)...

Chitosan biocompatibility and mucoadhesiveness make it an ideal polymer for antituberculotic drugs microcapsulation for pulmonary delivery. Yet, previous study indicated toxicity problems to J-774.1-cells treated with some medium molecular weight (190-310kDa) chitosan microparticles. As polymer molecular weight is a crucial factor to be considered, this paper describes the preparation and characterization of chitosan (50-190kDa) microparticles containing isoniazid (INH). Cytotoxicity assays were also performed on murine peritoneal (J-774...

INTRODUCTION: Activin receptor-like kinase 1 (ALK1) mediates signaling via the transforming growth factor beta-1 (TGFβ1), a pro-fibrogenic cytokine. No studies have defined a role for ALK1 in heart failure. HYPOTHESIS: We tested the hypothesis that reduced ALK1 expression promotes maladaptive cardiac remodeling in heart failure. METHODS AND RESULTS: In patients with advanced heart failure referred for left ventricular (LV) assist device implantation, LV Alk1 mRNA and protein levels were lower than control LV obtained from patients without heart failure...

Treatment of eating disorders like obesity or anorexia is challenging. Options are limited and new approaches desired. An interesting approach is the application of deep brain stimulation (DBS). The nucleus accumbens (NAcc) is part of the food reward system. A pilot study reported that DBS of the NAcc shell modulates food intake and body weight in rats. Underlying mechanisms such as the food intake microstructure are unknown so far. Normal weight female Sprague-Dawley rats were equipped with a custom-made DBS electrode placed unilaterally in the NAcc shell...

Epidemiological and experimental data suggest that obesity exacerbates the health effects of air pollutants such as ozone (O3). Maternal inactivity and calorically rich diets lead to offspring that show signs of obesity. Exacerbated O3 susceptibility of offspring could thus be manifested by maternal obesity. Thirty-day-old female Long-Evans rats were fed a control (CD) or high-fat (HF) (60% calories) diet for 6 wks and then bred. GD1 rats were then housed with a running wheel (RW) or without a wheel (SED) until parturition, creating four groups of offspring: CD-SED, CD-RW, HF-SED and HF-RW...

Although individual differences in fluid reasoning reliably mediate predictions of attention-deficit/hyperactivity disorder (ADHD) symptoms from birth weight in youth with typical cognitive development (TD), it is unknown if this indirect effect operates similarly in the development of ADHD symptoms secondary to intellectual disability (ID). Thus, we evaluated mediation by fluid reasoning in a longitudinal sample of 163 youth (45% female) with (n = 52) or without (n = 111) ID who were followed prospectively from age 5 to age 13...

Diffusion-weighted imaging (DWI) is used to measure gray matter tissue density and white matter fiber organization/directionality. Recent studies show that DWI also allows for assessing neuroplastic adaptations in the human hypothalamus. To this end, we investigated a potential influence of testosterone replacement therapy on hypothalamic microstructure in female-to-male (FtM) transgender individuals. 25 FtMs were measured at baseline, 4 weeks, and 4 months past treatment start and compared to 25 female and male controls...

The present study examined wear characteristics of A356/melon shell ash particulate composites. Dry-sliding the stainless steel ball against specimen disc revealed the abrasive wear behavior of the composites under loads of 2 and 5N. The composite showed lower wear rate of 2.182 × 10(-4) mm(3)/Nm at 20 wt% reinforced material under load of 5N. Results showed that wear rate decreased significantly with increasing weight percentage of melon shell ash particles. Microstructural analyses of worn surfaces of the composites reveal evidence of plastic deformation of matrix phase...
