Bone Plasticity in Response to Exercise Is Sex-Dependent in Rats

Purpose: To characterize the potential sexual dimorphism of bone in response to exercise.Methods: Young male and female Wistar rats were either submitted to 12 weeks of exercise or remained sedentary. the training load was adjusted at the mid-trial (week 6) by the maximal speed test. A mechanical test was performed to measure the maximal force, resilience, stiffness, and fracture load. the bone structure, formation, and resorption were obtained by histomorphometric analyses. Type I collagen (COL I) mRNA expression and tartrate-resistant acid phosphatase (TRAP) mRNA expression were evaluated by quantitative real-time PCR (qPCR).Results: the male and female trained rats significantly improved their maximum speed during the maximal exercise test (main effect of training; p<0.0001). the male rats were significantly heavier than the females, irrespective of training (main effect of sex; p<0.0001). Similarly, both the weight and length of the femur were greater for the male rats when compared with the females (main effect of sex; p<0.0001 and p<0.0001, respectively). the trabecular volume was positively affected by exercise in male and female rats (main effect of training; p = 0.001), whereas the trabecular thickness, resilience, mineral apposition rate, and bone formation rate increased only in the trained males (within-sex comparison; p<0.05 for all parameters), demonstrating the sexual dimorphism in response to exercise. Accordingly, the number of osteocytes increased significantly only in the trained males (within-sex comparison; p<0.05). Pearson's correlation analyses revealed that the COL I mRNA expression and TRAP mRNA expression were positively and negatively, respectively, related to the parameters of bone remodeling obtained from the histomorphometric analysis (r = 0.59 to 0.85; p<0.05).Conclusion: Exercise yielded differential adaptations with respect to bone structure, biomechanical proprieties, and molecular signaling in male and female rats.Univ São Paulo, Sch Med, Div Nephrol, São Paulo, BrazilUniv São Paulo, Sch Phys Educ & Sport, Dept Sports, São Paulo, BrazilUniv São Paulo, Inst Biomed Sci, Dept Anat, São Paulo, BrazilUniv São Paulo, Sch Med, Div Rheumatol, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Physiol Sci, São Paulo, BrazilUniversidade Federal de São Paulo, Dept Physiol Sci, São Paulo, BrazilWeb of Scienc

MEDICINES WASTE POLICIES AND THE POPULATION KNOWLEDGE IN BRAZIL

Objective: To investigate the degree of knowledge of the patients enrolled in the Unified Health System of the Medicine School of ABC (Faculdade de Medicina do ABC) regarding the proper use and disposal of medicaments. Methods: Participants were recruited for convenience, during their medical appointments at the clinic of the Medical School of ABC (Santo André, Sao Paulo, Brazil) in the period from 04 August to 30 September 2014. Data collection was conducted through a self-administered poll designed specifically for the purpose of this study, which consisted of 25 questions multiple choice about socioeconomic issues and the subject disposal of drugs, consumption and environmental pollution. Results: We selected the 140 patients’ polls. Most of them is of white ethnicity (58%) and female (58%). Level of education: 31% have completed secondary education (31%) or incomplete graduation (19%). Most of the participants (76%) buy drugs without a prescription, and most families (76%) seek understanding by reading the labels. 71.43% reported knowing that incorrect disposal of drugs could contaminate the environment, but 78% reported never having seen or received information about these. After using, 22.15% maintains the medication at home for future use, 55% of subjects reported improper disposal sites and 13% are delivered in health care institutions. Conclusion: Our study has showed that most participants inappropriately use and dispose of drugs, even though they know they can contaminate the environment

Innate immunodeficiency following genetic ablation of Mcl1 in natural killer cells

The cytokine IL-15 is required for natural killer (NK) cell homeostasis; however, the intrinsic mechanism governing this requirement remains unexplored. Here we identify the absolute requirement for myeloid cell leukaemia sequence-1 (Mcl1) in the sustained survival of NK cells in vivo. Mcl1 is highly expressed in NK cells and regulated by IL-15 in a dose-dependent manner via STAT5 phosphorylation and subsequent binding to the 3'-UTR of Mcl1. Specific deletion of Mcl1 in NK cells results in the absolute loss of NK cells from all tissues owing to a failure to antagonize pro-apoptotic proteins in the outer mitochondrial membrane. This NK lymphopenia results in mice succumbing to multiorgan melanoma metastases, being permissive to allogeneic transplantation and being resistant to toxic shock following polymicrobial sepsis challenge. These results clearly demonstrate a non-redundant pathway linking IL-15 to Mcl1 in the maintenance of NK cells and innate immune responses in vivo

The role of soluble fiber intake in patients under highly effective lipid-lowering therapy

<p>Abstract</p> <p>Background</p> <p>It has been demonstrated that statins can increase intestinal sterol absorption. Augments in phytosterolemia seems related to cardiovascular disease.</p> <p>Objective</p> <p>We examined the role of soluble fiber intake in endogenous cholesterol synthesis and in sterol absorption among subjects under highly effective lipid-lowering therapy.</p> <p>Design</p> <p>In an open label, randomized, parallel-design study with blinded endpoints, subjects with primary hypercholesterolemia (n = 116) were assigned to receive during 12 weeks, a daily dose of 25 g of fiber (corresponding to 6 g of soluble fibers) plus rosuvastatin 40 mg (n = 28), rosuvastatin 40 mg alone (n = 30), sinvastatin 40 mg plus ezetimibe 10 mg plus 25 g of fiber (n = 28), or sinvastatin 40 mg plus ezetimibe 10 mg (n = 30) alone.</p> <p>Results</p> <p>The four assigned therapies produced similar changes in total cholesterol, LDL-cholesterol, and triglycerides (p < 0.001 vs. baseline) and did not change HDL-cholesterol. Fiber intake decreased plasma campesterol (p < 0.001 vs. baseline), particularly among those patients receiving ezetimibe (p < 0.05 vs. other groups), and β-sitosterol (p = 0.03 vs. baseline), with a trend for lower levels in the group receiving fiber plus ezetimibe (p = 0.07). Treatment with rosuvastatin alone or combined with soluble fiber was associated with decreased levels of desmosterol (p = 0.003 vs. other groups). Compared to non-fiber supplemented individuals, those treated with fibers had weight loss (p = 0.04), reduced body mass index (p = 0.002) and blood glucose (p = 0.047).</p> <p>Conclusion</p> <p>Among subjects treated with highly effective lipid-lowering therapy, the intake of 25 g of fibers added favorable effects, mainly by reducing phytosterolemia. Additional benefits include improvement in blood glucose and anthropometric parameters.</p
