Abstract: Background: Creatine supplementation is a subject that is very well studied. New forms of creatine are suggesting improvements in this supplement performance. Creatine HCl is supposed to have better solubility and absorption than creatine. The aim of this study was to compare the effects of two different doses of creatine HCl with creatine monohydrate on the strength and body composition in recreational weightlifters and to verify the relationship between strength and body composition. Methods: 40 subjects were divided in four groups: Creatine Monohydrate (CMG) 5 g/daily; Creatine HCl-1 (HCl-1) 5 g/daily, Creatine HCl-2 (HCl-2) 1.5 g/daily and Control group (CG) = 5 g of resistant starch/daily. All groups performed a resistance training program during 4 weeks. Body composition and strength were evaluated pre and post intervention. Results: The 1 RM at the Leg press was increased significantly in all groups (CMG: pre = 264.4 ± 83.8 × post = 298.1 ± 90.9; HCl-1: pre = 295.0 ± 88.3 × post = 338.3 ± 86.8 and HCl-2: pre = 274.3 ± 57.1 × post = 305.7 ± 59.4; p< 0.05), Bench press 1 RM was increased significantly only in HCl-2 (pre = 72.4 ± 25.7 × post = 76.0 ± 25.0; p = 0.003), however, there was no statistically significant difference between groups. Fatmass was significantly decreased in HCl-1 (pre = 14.5 ± 8.0 × post = 13.3 ± 8.3; p = 0.034) and HCl-2 (pre = 13.8 ± 5.8 × post = 12.7 ± 5.6; p = 0.005) but fat-free mass was increased only in HCl-1 (pre = 52.2 ± 8.9 × post = 53.8 ± 8.9; p = 0.031), with no differences between groups again. We observed strong correlations between upper limb strength and fat mass (r = 0.93, p < 0.05), and between lower limb strength and FFM (r = 0.93, p < 0.05) only in HCl-1 group. Conclusions: We concluded that creatine HCl and creatine Monohydrate improve performance but only creatine HCl induces changes on body composition in recreational weightlifters with differences between creatine HCl doses.

Abstract: the state of espírito santo has been recognized as one of the richest brazilian states in terms of species diversity, but the knowledge on its mammal fauna is still limited. due to the lack of a complete list of wild mammals occurring in the state and to the scarcity of information associated to species records, we carried out a study on the state of scientific knowledge on mammal species in the state of espírito santo. we compiled a digital database with locality records of mammal species from published data and museum specimens. we used the software diva to verify where efforts for recording mammals are located and also where species richness is higher. as a result, we generated a list of 138 espírito santo mammals, which includes threatened animals and atlantic forest endemic species, and two species typical of the cerrado. we found regions that are knowledge gaps, especially in the northern part of the state. there have been more mammal surveys in the micro regions "central serrana" and "pólo linhares". the list of mammal species is a guideline for future research, even though it is not exhaustive. we recommend conducting faunal surveys focusing on larger geographic areas and intensive sampling efforts, mainly in those regions where information is scarce.

Open Access Library Journal (OALib Journal) , 2014, DOI: 10.4236/oalib.1100666
Abstract: Melanocytes are pigment-producing cells originated from the neural crest. Epidermal melanocytes contribute to photoprotection and thermoregulation by packaging melanin pigment intomelanosomes and sending them to keratinocytes. There are still many gaps in the understanding of early events of melanocyte differentiation and advanced melanoma regarding genetic and molecular processes. In this review, the authors present a summary of the main aspects of the melanocyte biology and its relation with the melanoma etiology, which are of major importance for guiding novel therapies development and to well understand this disease.

Abstract: interactions between two endocrine disruptors (ed) and aquatic humic substances (ahs) from tropical rivers were studied using an ultrafiltration system equipped with a 1 kda cut-off cellulose membrane to separate free ed from the fraction bound in the ahs. quantification of 17α-ethynylestradiol and bisphenol a was performed using gas chromatography-mass spectrometry (gc-ms). the times required for establishment of equilibrium between the ahs and the ed were ca. 30 min, and complexation capacities for 17α-ethynylestradiol and bisphenol a were 18.53 and 2.07 mg g-1 toc, respectively. the greater interaction of ahs with 17α-ethynylestradiol, compared to bisphenol a, was due to the presence of hydrogen in the structure of 17α-ethynylestradiol, which could interact with ionized oxygenated groups of the ahs. the results indicate that ahs can strongly influence the transport and reactivity of endocrine disruptors in aquatic systems.

Abstract: Various mouse models to study dengue have been described by different authors, some of them using immunodeficient or some using humanized mice. Our group reported previously a deadly murine model, which used the intracranial inoculum of highly virulent Dengue virus (DENV) in immune competent mouse. Here we present a model of immune competent mouse (C57BL/6), infected subcutaneously by the same highly virulent DENV (DENV3 genotype I). In this immunocompetent systemic mice model, the cytokine levels and hematological parameters such as total and differential leukocyte and platelets counts, together with weight loss, were considered important monitoring parameters, allowing a better understanding of the systemic human disease. Mice were inoculated subcutaneously and evaluated by the percentage weight variation as well as the clinical signs. Hematological parameters and cytokines levels were measured and viral titration in brain tissue or serum neutralization was performed to confirm mice infection. The subcutaneously DENV inoculated mice showed weight loss after infection, but they did not show any other clinical signs. The leukocytes and platelets decreased after subcutaneous inoculation. The cytokines TNF alpha and IFN gamma increased after infection in mice. The subcutaneous model provided scope for improved understanding of the dengue pathogenesis, as well as possible mechanism for protection to subsequent mouse infected by intracranial route in mice. This model could be used to study the vertebrate immune response and evaluation of drugs or vaccine against dengue virus.

Abstract: the aim of this study was to evaluate the influence of the high values of insertion torques on the stress and strain distribution in cortical and cancellous bones. based on tomography imaging, a representative mathematical model of a partial maxilla was built using mimics 11.11 and solid works 2010 softwares. six models were built and each of them received an implant with one of the following insertion torques: 30, 40, 50, 60, 70 or 80 ncm on the external hexagon. the cortical and cancellous bones were considered anisotropic. the bone/implant interface was considered perfectly bonded. the numerical analysis was carried out using ansys workbench 10.0. the convergence of analysis (6%) drove the mesh refinement. maximum principal stress (??max) and maximum principal strain (?μmax) were obtained for cortical and cancellous bones around to implant. pearson's correlation test was used to determine the correlation between insertion torque and stress concentration in the periimplant bone tissue, considering the significance level at 5%. the increase in the insertion torque generated an increase in the ??max and ?μmax values for cortical and cancellous bone. the ??max was smaller for the cancellous bone, with greater stress variation among the insertion torques. the ?μmax was higher in the cancellous bone in comparison to the cortical bone. according to the methodology used and the limits of this study, it can be concluded that higher insertion torques increased tensile and compressive stress concentrations in the periimplant bone tissue.
