Human and ecological risks of BDE-209 have drawn much attention, particularly with growing e-waste recycling activities in developing countries. To further address the issue of BDE-209 biotransformation, a laboratory-controlled study was conducted. Female Sprague-Dawley rats were dosed orally by gavage at a daily dose of 1 mg kg(-1) body weight for 7 d and a depuration period of 22 d, to characterize absorption, distribution, metabolism, and elimination dynamics of BDE-209 during multi-dose exposures simulating short-term oral exposure of e-waste workers...

Analogs of anorexigenic neuropeptides, such as prolactin-releasing peptide (PrRP), have a potential as new anti-obesity drugs. In our previous study, palmitic acid attached to the N-terminus of PrRP enabled its central anorexigenic effects after peripheral administration. In this study, two linkers, γ-glutamic acid at Lys11 and a short, modified polyethylene glycol at the N-terminal Ser and/or Lys11, were applied for the palmitoylation of PrRP31 to improve its bioavailability. These analogs had a high affinity and activation ability to the PrRP receptor GPR10 and the neuropeptide FF2 receptor, as well as short-term anorexigenic effect similar to PrRP palmitoylated at the N-terminus...

Post kala-azar dermal leishmaniasis (PKDL) is a skin manifestation which usually appears after visceral leishmaniasis. It is now proved that PKDL patients serve as a reservoir for anthropometric leishmanial transmission. Hence, to achieve the kala-azar elimination target set by the World Health Organization in the Indian Subcontinent, PKDL cases should be given priority. The goal of treatment for PKDL should be early reepithelizlization and rapid cure, but unfortunately this has been difficult to achieve, especially for patients with severe lesions...

A rear mounted, powered, drive wheel has been developed to assist with mobility for manual wheelchairs in indoor and outdoor modes. To start the wheel, users must initiate handrim propulsion with sufficient force to trigger the motor. To stop the indoor mode, users must apply a braking force through the handrims exceeding the device's deceleration threshold. The objectives of this study were to compare 1) the minimum force required to start a wheelchair with and without the wheel, and 2) the distances and forces needed to stop a wheelchair at different treadmill speeds (3...

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...

For many years metformin has been the gold standard in the treatment of type 2 diabetes. According to recommendations of the most important diabetes associations, this is the first-choice drug for use as monotherapy in patients with newly diagnosed type 2 diabetes. Metformin is also recommended in combined treatment when monotherapy is no longer effective. It is then combined with a sulfony-lurea, an incretin, flozin, or insulin, irrespective of the number of insulin injections per day. Besides its properties used in the treatment of diabetes, metformin has been treated for some time as a drug of a so-called pleiotropic activity, as each year brings new reports about its favourable effect in different conditions...

Cardiac mitochondrial oxidative stress causes mitochondrial damage that plays an important role in the pathology of myocardial infarction. The preventive effects of diosmin on cardiac mitochondrial oxidative stress in isoproterenol-induced myocardial infarcted rats were evaluated. Rats were pretreated with diosmin (10 mg/kg body weight) daily for 10 days. Myocardial infarction was induced in rats by isoproterenol (100 mg/kg body weight) injection twice at an interval of 24 h (on 11th and 12th day). Isoproterenol-induced myocardial infarcted rats showed a significant increase in the levels of cardiac diagnostic markers, heart mitochondrial lipid peroxidation, calcium ion, and a significant decrease in the levels of heart mitochondrial glutathione peroxidase, reduced glutathione, glutathione-S-transferase, isocitrate, malate, α-ketoglutarate, and succinate dehydrogenases...

BACKGROUND: We aimed to evaluate the effect of health literacy on agreement for bariatric surgery among morbidly obese patients. METHODS: The data of 242 morbidly obese patients (body mass index-BMI ≥ 40 kg/m(2)) were evaluated in a cross-sectional case-control pattern. The patients were classified into two groups as those who were attending the clinic for the purpose of receiving bariatric surgery (n = 138) and those who did not (n = 104). The Turkish version of the European Health Literacy Survey Questionnaire (HLS-EU-Q47), consisting of 47 questions, was used for the health literacy evaluation...

A unique case of accidental hanging due to compression of the neck of an adult by the branches of a coffee tree is reported. The decedent was a 42-year-old male who was found dead in a semi prone position on a slope. His neck was lodged in a wedge formed by two branches of a coffee tree, with his legs angled downwards on the slope. Autopsy revealed two friction abrasions located horizontally on either side of the front of the neck, just above the larynx. The findings were compatible with compression of the neck by the branches of the tree, with the body weight of the decedent contributing to compression...

BACKGROUND AND AIMS: The brain reward system is key to understanding adolescent obesity in the current obesogenic environment, rich in highly appetising stimuli, to which adolescents are particularly sensitive. We aimed to examine the association between body fat levels and brain reward system responsivity to general (monetary) rewards in male and female adolescents. METHOD: Sixty-eight adolescents (34 females; mean age [standard deviation]=16.56 [1.35]) were measured for body fat levels with bioelectric impedance, and underwent a functional magnetic resonance imaging (fMRI) scan during the Monetary Incentive Delay (MID) task...

Obesity is considered as a worldwide problem in both males and females. Although many studies have demonstrated the efficiency of oxytocin (Oxt) as an anti-obesity peptide, there is no comparative study of its effect in males and females. This study aims to determine factors (sex, initial body weight, and fat distribution) that may affect the ability of Oxt to regulate body weight (BW). With regard to sex, Oxt reduced BW similarly in males and females under both high fat diet (HFD) and standard chow-fed condition...
