A radiologic morphometric study of sellar, infrassellar and parasellar regions by magnetic resonance in adults

To evaluate variations of some anatomic structures of sellar and parasellar regions and their possible differences between genders and age groups. Magnetic resonance images (MRI) of 380 patients were performed to analyze the dimensions of the sphenoid sinus, pituitary gland, optic chiasm, intra-cavernous carotid distances, distance between columella nasal - sphenoid sinus; and columella nasal-pituitary gland. The patients age ranged between 20 and 80 years (mean age 48 years). The study included 235 females (mean age 53 years) and 145 males (mean age 40 years). The transverse length of the pituitary, the inter-carotid distance and the height of the pituitary were similar between genders and age groups. The width and height of the optic chiasm showed differences only between females of different ages. Males presented greater distances between nasal columella and sphenoid sinus. The most common type of pneumatization of the sphenoid sinus was the sellar, and depending on the age group, sphenoid sinus was larger in males than females. The anatomy of the Sellar and parasellar regions is complex and varies widely within the normal range. They are a small area, rich in anatomical details affecting multiple physiological systems in the body and, therefore, have great importance in several medical fields. A better understanding of these complex structures is essential in clinical diagnosis and treatment of disease.

A review of pharmacokinetic parameters of metabolites and prodrugs

In drug discovery and development, the kinetic study of active metabolites plays an important role, helping to define the time course of the drug in the body and its activity or toxicity. After a pharmacokinetics assessment of a drug and its metabolite or a prodrug and its parent-drug, several parameters can be calculated. In some cases, achieving the objective of the study does not require all possible parameters to be calculated. When parameters are calculated, it is essential that their denotations are widely accepted and used. However, some parameters undergo a certain variability of denotation, which may confuse some readers. Thus, this review summarizes the current published data for experimental pharmacokinetic parameters of metabolites and the calculations involved in simple metabolite pharmacokinetic studies. It also evaluates the most common pharmacokinetic parameters in the literature and suggests metabolite parameters that could be determined to help advance metabolite kinetic models.

Prevalence of and risk factors for bacterial vaginosis among women of reproductive age attending cervical screening in southeastern Brazil

To determine the prevalence of and risk factors for bacterial vaginosis. A cross-sectional study of women aged 14-54 years attending 18 primary healthcare units in Botucatu, Brazil, for cervical screening was undertaken between September 1, 2012, and January 31, 2013. Data on sociodemographics, sexual behavior, and medical history were obtained by interview. Vaginal swabs were taken to classify the vaginal flora according to the Nugent scoring system. Candida sp. hyphae and infection by Trichomonas vaginalis were also evaluated by microscopy and culture, respectively. Stepwise logistic regression analysis was performed to identify risk factors independently associated with bacterial vaginosis. Among 1519 women included in analyses, 457 (30.1%) had bacterial vaginosis. Variables independently associated with bacterial vaginosis were a single marital status (OR 1.4; 95%CI 1.1-1.8), partner infidelity (OR 1.5; 95%CI 1.2-1.9), abnormal discharge in the previous year (OR 1.5; 95%CI 1.2-2.0), and concurrent trichomoniasis (OR 4.1; 95%CI 1.5-11.5). Current use of hormonal contraception (OR 0.7; 95%CI 0.5-0.9), luteal phase of menstrual cycle (OR 0.8; 95%CI 0.6-0.9), higher income (OR 0.8; 95%CI 0.6-0.9), and vaginal candidiasis (OR 0.5; 95%CI 0.3-0.9) all had protective effects. The prevalence of bacterial vaginosis in the study population is high. The epidemiological data provide evidence of the sexual transmissibility of bacterial vaginosis.

Entre os muros da escola: o saber experiencial emergente nas aulas de educação física da periferia

This study aimed to analyze the teachers´ knowledge of a physical education teacher network state of São Paulo. The interviewed reported having problems regarding the use of the court, especially because there is invasion of the community to smoking marijuana and/ou playing football, revealing the predominance of experiential knowledge to work in a new school, whose location and local culture do not seem to prioritize this social space as learning, dissemination and preservation of other bodily manifestations of the process of human civilization. It was found in such a setting an imbalance of the relative strengths of power between teacher and students, from schools, football and drugs in relation to body movement culture, it being understood that the relationships between these individuals are interdependent and dynamic. Finally, it urges an integrated process in educational, family, social and political fields from the perspective of balancing forces in relation to the use of that space, providing conditions for teaching and propagation of content (games, sports, gymnastics, dances and fights) of the body movement culture.

O skate na cultura corporal de movimento: aspectos evolutivos e sociais

Skateboarding gets practitioners and followers all over the world and it's still growing. Thus performing a detailed analysis of its tracks becomes exciting. This study has a purpose of investigation about the evolution of the skateboard as a leisure activity and as a sport, supported by historical and social factors analysis that influenced their growth. Furthermore to understand the sport history and its influence in the socialization process, and also in the insertion of individuals in a social context within the body movement culture. The methodology used in this study was based on a literature review, analyzing articles, books, documents, websites and reports of the genre. It was concluded that the practice of skateboarding is unique and it's promoted to be and to have self identity and it is directly related to an activity that is characterized as free and creative without any molded identity. And also promote the insertion of this kind of skateboarding as a universal phenomenon about the body movement seeking social interactions in different educational views through a sharing attitude

Influência das aulas de educação física na prática de atividades esportivas iniciais

The sports activities occupy a growing space in people's lives, especially children and youth. Taking into consideration that this practice is of paramount importance, especially in childhood, where the acquired habits influence in adulthood, this work aims to investigate the role of physical education classes in adherence of children to the practice of some activity sports. These are a dynamic process, and to realize it is necessary planning, making the practice is a pleasurable activity. Thus, an important point to note is the motivation, which depends on extrinsic and intrinsic factors. Another factor that may interfere in the sporting practices is the influence of parents on children. In this context, the contact sports can be used to gain the approval of parents and not for self-gratification, this being a way to get closer to distant parents. A point worth mentioning is the physical education, as this introduces and integrates the child's body / movement culture. Often child's first contact with the sport happens at school, leading us to the assumption that the physical education teachers at the school are responsible for the athletic student motivation, and we emphasize that the school motivational factors are very dependent on students' aspirations for that a particular motivational element can take effect. The technical and / or professional outside of school physical education also influence the child, as these can provide pleasure for the sport, being a connoisseur of motivational strategies. An important motivational aspect is friendship, as children use sports activities to make new friends and find your friends. In addition, some extrinsic factors can influence the practice, such as: win, work out, play, socializing, competition, fun, etc. The drop can be caused by various reasons, such as early specialization, participation in very specific competitions for which the child is not yet ready. In addition, other factors can be...

Effects of abiotic factors on growth and chemical defenses in cultivated clones of Laurencia dendroidea J. Agardh (Ceramiales, Rhodophyta)

Laurencia dendroidea shows high inter- and intrapopulation variability in the amount of the sesquiterpene elatol, caused by genetic variation as well as environmental factors. To test the independent effect of physical and nutritional conditions, the growth and the levels of elatol in L. dendroidea clones were evaluated under different conditions of temperature, salinity, irradiance, and culture medium in the laboratory. Growth of L. dendroidea was clearly affected by all these factors, but elatol levels were influenced only by temperature and salinity. Better conditions for growth did not produce a similar effect on elatol production in L. dendroidea, contradicting the carbon/nutrient balance and growth/differentiation balance models. On the contrary, severe conditions of temperature and salinity promoted a decrease in elatol levels, as predicted by the environmental stress model. Our results using clones indicated that abiotic factors clearly take part in fostering chemical variations observed in natural populations, in addition to genetic factors, and can promote differential susceptibility of plant specimens to natural enemies.

A idéia de corpo e a configuração do ambiente da improvisação musical

O objetivo deste texto é evidenciar a importância da ideia de corpo para a reflexão sobre o ambiente da improvisação musical. Este tipo de prática em tempo real que parte de uma relação direta dos músicos com os seus instrumentos sem a mediação de uma partitura tem como ponto de partida inevitável o corpo dos improvisadores envolvidos. O corpo funciona tanto como um fator de reprodução de possíveis – refletindo os limites do próprio corpo (repetição) - quanto como um potencializador de produção de virtualidades – fundamentados numa expansão destes limites (diferença). Trata-se então de examinar, no agenciamento da improvisação, como o corpo pode ser entendido como detentor deste duplo dinamismo e, neste contexto, que tipo de relacionamento pode estabelecer com a matéria sonora. Procuraremos também estabelecer o papel das ideias de desejo e prazer na configuração deste dinamismo e relacionar esta reflexão com as propostas de improvisação livre e idiomática. Para esta discussão serão utilizados alguns conceitos formulados por Gilles Deleuze como território e linha de fuga, as reflexões de Paul Zumthor sobre corpo, oralidade e performance e as discussões epistemológicas de Edgar Morin sobre o conhecimento e a cultura

Kinetic Analysis of Gill (Na+,K+)-ATPase Activity in Selected Ontogenetic Stages of the Amazon River Shrimp, (Decapoda, Palaemonidae): Interactions at ATP- and Cation-Binding Sites

We investigated modulation by ATP, Mg2+, Na+, K+ and NH4 (+) and inhibition by ouabain of (Na+,K+)-ATPase activity in microsomal homogenates of whole zoeae I and decapodid III (formerly zoea IX) and whole-body and gill homogenates of juvenile and adult Amazon River shrimps, . (Na+,K+)-ATPase-specific activity was increased twofold in decapodid III compared to zoea I, juveniles and adults, suggesting an important role in this ontogenetic stage. The apparent affinity for ATP ( (M) = 0.09 +/- A 0.01 mmol L-1) of the decapodid III (Na+,K+)-ATPase, about twofold greater than the other stages, further highlights this relevance. Modulation of (Na+,K+)-ATPase activity by K+ also revealed a threefold greater affinity for K+ ( (0.5) = 0.91 +/- A 0.04 mmol L-1) in decapodid III than in other stages; NH4 (+) had no modulatory effect. The affinity for Na+ ( (0.5) = 13.2 +/- A 0.6 mmol L-1) of zoea I (Na+,K+)-ATPase was fourfold less than other stages. Modulation by Na+, Mg2+ and NH4 (+) obeyed cooperative kinetics, while K+ modulation exhibited Michaelis-Menten behavior. Rates of maximal Mg2+ stimulation of ouabain-insensitive ATPase activity differed in each ontogenetic stage, suggesting that Mg2+-stimulated ATPases other than (Na+,K+)-ATPase are present. Ouabain inhibition suggests that, among the various ATPase activities present in the different stages, Na+-ATPase may be involved in the ontogeny of osmoregulation in larval The NH4 (+)-stimulated, ouabain-insensitive ATPase activity seen in zoea I and decapodid III may reflect a stage-specific means of ammonia excretion since functional gills are absent in the early larval stages.
