Introduction: Obesity has been considered a global epidemic and a serious public health problem closely related to other diseases. Moreover, obese individuals have limitations in physical capacity and pulmonary function. Weight loss induced by bariatric surgery appears to help reverse this situation. However, questions about physical capacity and lung function, and its relationship with body composition remain to be clarified. Objective: To evaluate the physical capacity, body composition and lung function in women undergoing bariatric surgery. Methods: Twenty five women who underwent bariatric surgery between 6 and 24 months ago, and 10 non-obese women were evaluated for exercise capacity by the six minutes walk test (6 MWT), body composition by bio-electrical impedance analysis and lung function by spirometry and measurement of maximal static respiratory pressures. Results: Subjects with BMI <30 kg/m2 were found to have better physical performance, demonstrated by increased 6 MWT distance, not differing from non-obese women. When compared with non-obese women, there were no significant differences in body composition and lung function. Higher BMI was correlated with shorter distances in 6 MWT. Conclusion: 6 to 24 months after surgery, when the weight loss of patients who underwent bariatric surgery reaches levels considered non-obese, it provides improvement in physical performance to a level similar to that of non-obese patients.

Abstract: Objective: To compare clinical outcomes between two first-generation endometrial ablation techniques. Design: Prospective comparative coorte. Setting: Tertiary public hospital, university teaching center. Seventy-three patients with abnormal uterine bleeding unresponsive to clinical treatment submitted to endometrial ablation from October 2011 to September 2013. Methods and Main Outcome Measures: Patients were assigned to either monopolar U-shaped electrode resection with rollerball electrocoagulation (group A, n = 36) or rollerball electrocoagulation alone (group B, n = 37). Mean follow-up length was 359 (280 - 751) and 370 days (305 - 766) in groups A and B, respectively. Bleeding pattern, associated symptoms, failure/success rates were assessed 30, 90, 180 and 360 days post-procedure. Findings: Patient characteristics were similar in both groups (P ≥ 0.05). Surgery duration (mean of 48.5 [±12.0] vs. 31.9 [±5.6] min, P < 0.001) and medium distention use (5.700 mL vs. 3.500 mL, P < 0.01) were decreased in group B. Post-ablation clinical improvement was considerable in both groups. Vaginal discharge incidence after the procedure was lower in group B (30.5% vs. 8.1%, P < 0.05). Hysterectomy rate was 9.6%. Overall success rate was 86.1% and 88.1% in groups A and B, respectively. Conclusions: Endometrial ablation using rollerball electrocoagulation alone may be considered safer than resection with rollerball electrocoagulation, which requires shorter surgical time and less distention medium, and is associated with lower postoperative vaginal discharge incidence. Success rate did not statistically differ between groups, but study parameters in absolute values and percents were superior in group B.

Abstract: natural selection acts to select better adapted individuals or alleles in segregating population and help plant breeding. the objective of this work was to verify the effect of natural selection on microsatellite alleles as indicators of better adaptation and identification of quantitative trait loci (qtls) for grain yield. this study evaluated 107 progenies from the f8 and 107 from the f24 generation derived from crossing carioca mg and esal 686 lines, carried out by the bulk method, and evaluated in three different seasons: winter 2001; rainy 2001 and dry 2002. it was utilized 22 polymorphic markers and the natural selection acted in all of them. the frequency of the alleles of the parent carioca mg, the most adapted, was increased in all of the 22 loci in f8 and 19 loci in f24. selection affected each locus with different intensities in different generations. all of the selected alleles can be important for breeding program. qtls were identified in generation f8 and f24 at varied magnitudes. the best marker pvttc002 explained 11.76% of variation in grain yield. however, an elevated interaction between qtls and the environments was observed, showing the great difficulty in assisted selection.

Abstract: molecular markers may accelerate selection through the identification of plants with higher proportion of recurrent parent genome, as well as identifying those plants bearing target alleles like quantitative traits loci (qtls) for white mold resistance. the objectives of this work were: 1) to employ microsatellite markers (ssr) in order to accelerate the recovery of recurrent parent genome 2) to validate sequence characterized amplified region (scar) phs associated with a qtl that confers resistance to white mold, as previously identified in bean populations. lines g122 and m20 were crossed, which generated 267 f1 plants from backcross (bc) bc1 and 113 plants from backcross bc2.ssr polymorphic markers were adopted. the relationship between bc plants and the recurrent parent was estimated based on the recurrent genome proportion (pr) in each bc plant, and the sorensen-dice genetic similarity (sgir). to determine how much the phenotypic variation is explained by scar phs, 56 f1:2bc1 progenies were evaluated on the field following a random block design with two replications through the straw test method. ssr markers are efficient in identifying individuals with a greater proportion of the recurrent genome. scar phs was not efficient for the indirect selection of common beans for white mold resistance.

Journal of Epilepsy and Clinical Neurophysiology , 2006, DOI: 10.1590/S1676-26492006000200003
Abstract: temporal lobe epilepsy (tle), the most frequent type of focal epilepsy in adults, is characterized by resistance to pharmacological treatment, progressive hipocampal neuronal loss and impairment of cognitive and neuropsychological performances. studies with human specimens and experimental animal models have demonstrated exuberant and dynamic neuronal plasticity phenomena in the hipocampal formation associated with tle. the study of these phenomena is fundamental for the definition of the genesis and progression mechanisms of epilepsy and for the development of better therapeutic strategies than those current available. in this article, we review neuronal and glial plastic alterations as neuronal death and birth, dendritic spine formation, axonal sprouting, gliosis and gap junction establishment and their role in the pathophysiology of tle.

Anais Brasileiros de Dermatologia , 2012, DOI: 10.1590/S0365-05962012000200015
Abstract: a giant congenital melanocytic nevus represents a rare condition. the halo phenomenon may be seen in congenital or acquired melanocytic nevi. in the literature, association of halo nevus and giant congenital melanocytic nevus is rare and the association of both with vitiligo even more rare. a 75-yearold woman at first consultation complained of a hyperchromic bluish-brown hairy macula on the lower back, buttocks and thighs present since birth and an achromic halo of onset three years ago. the histological features were consistent with congenital melanocytic nevus and halo nevus, respectively. after two years the patient developed achromic areas in normal skin, histologically consistent with vitiligo. the authors emphasize the rarity of this triple combination, the patient's age and the absence of malignant degeneration to date.
