Effects of thymoquinone on testicular structure and sperm production in male obese rats.

This study investigated the effects of TQ on obesity and testicular structure of high-fat-diet (HFD) fed rats. Obese control (OC) and obese thymoquinone (OT) groups were fed a special diet containing 40% of total calories from fat. Non-obese control (NC) and non-thymoquinone (NT) groups were fed a standard diet for nine weeks. Then, intraperitoneal TQ injections were carried out to the OT and NT groups for six weeks and testes were removed. Catalase and myeloperoxidase activity were determined in rat testis tissue. Stereological, histopathological, and immunohistochemical changes were evaluated in the testes of the rats. In stereological studies, mean volumes of testis and seminiferous tubules, the number of spermatogenic cells and also Leydig cells in the OC group were reduced, but these values significantly increased in the OT group. Apoptotic cells were observed in the OC group in comparison to the OT group. The number of healthy sperms were reduced in the OC group, whereas the majority showed anomalies in the head, neck, and tail. The number of healthy sperm was increased and the anomalies significantly reduced by using TQ in both the NT, and especially the OT group. TQ like antioxidants may improve fertility by means of increasing the healthy sperm number and preventing sperm anomalies. PMID: 26043060 [PubMed - as supplied by publisher]

Abdel-HamidAbstractColorectal cancer (CRC) is a major public health concern and one of the main causes of cancer-related deaths worldwide. Of different risk factors for developing CRC, obesity plays a vital key role in colorectal carcinogenesis due to the perturbation in the metabolic and lipid profiles of obese candidates. The aim of this study is to decipher the disturbed metabolites associated with CRC susceptibility in at-risk obese populatio...

In this study, fluorescence emission spectroscopy and mass spectrometry (MALDI-TOF) were employed to define the putative interaction sites and their accessibility for the biologically important metals of Irving William Series.Key findingsSeveral hotspot residues in the ZAG scaffold involved in these interactions were mapped and their binding affinity score for each metal has been determined. Their binding abilities of these sites and aggregation propensities of ZAG were monitored by fluorescence emission spectroscopy.SignificanceThe prediction of such binding affinity with metals on the active sites and its impact on the c...

Authors: Shiroma PR, Velasquez T, Usset TJ, Wilhelm JH, Thuras P, Baltutis E Abstract INTRODUCTION: Obesity is prevalent among users of Veteran's Health Administration services, where it is comorbid with depression, post-traumatic stress disorder, type 2 diabetes, cardiovascular disease, colon, and breast cancer. Among obese subjects, severe obesity represents a subpopulation with the highest risk of depression. We investigate the antidepressant effect of a local VA weight management program (Managing Overweight Veterans Everywhere - MOVE) among depressed veterans with severe obesity.

Introduction: Bioelectrical impedance vector analysis (BIVA) is a non-invasive method for measuring body composition. The “InForma” trial has been designed to measure improvement of adherence to a healthy diet and/or to increase physical activity in order to promote weight loss in overweight or obese breast cancer survivors. Breast cancer survivors frequently face progressive weight gain and diminution of physical activity.

Introduction: Breast cancer (BC) is the most common cancer in women and the 5-year survival rate is 82% in Europe. Obesity, metabolic syndrome and diabetes are associated with an increased risk of BC and BC recurrence. Physical activity (PA), Mediterranean diet (MeD) and low glycemic index (GI) or high fiber diets, however, are protective.
