Abstract: the objective of this study was to evaluate the use of corn grains in different forms (corn dry grain, high moisture corn silage, moisturized corn silage) in the diet of confined lambs, and its possible effects on the qualitative and quantitative characteristics of the carcass. twenty male bergamacia x corriedade lambs were used. the animals were confined and fed ad libitum, assigned to five treatments consisted of dry corn: high moisture corn silage or moisturized corn silage (0:100, 50:50, 100:0). there was not effect of the treatments on the main carcass characteristics. the average true yield of carcass was 51.5%, while the yield of commercial carcass was 42.4%. differences were not observed between the variable body condition and conformation of the carcass, in function of the treatments. the variables fat covering, fat color and fat thickness were similar. the forms of the corn grains used in the feeding of the lambs did not affect the qualitative and quantitative characteristics of the carcass.

Abstract: Objectives. To provide a better understanding of the distribution of inguinal nodes in order to prevent the complications of unnecessary and extended dissections in penile cancer. Methods. The bilateral inguinal regions of 19 male cadavers were dissected. Nodal distribution was noted and quantified based on anatomical location. The superficial nodes were subdivided into quarters as follows: superomedial, superolateral, inferomedial, and inferolateral. Statistical analysis was performed comparing node distribution between quarters using one-way analysis of variance (ANOVA), and the unpaired T-test was used between superficial and deep nodes. Results. Superficial nodes were found in all inguinal regions studied (mean = 13.60), and their distribution was more prominent in the superomedial quarter (mean = 3.94) and less in the inferolateral quarter (mean = 2.73). There was statistical significance between quarters when comparing the upper group with the lower one ( ). Nodes were widely distributed in the superficial region compared with deep lymph nodes (mean = 13.60 versus 1.71, ). Conclusions. A great number of inguinal lymph nodes are distributed near the classical anatomical landmarks for inguinal lymphadenectomy, more prominent in upper quadrants. 1. Introduction Penile cancer is an aggressive and mutilating disease that deeply affects the patient’s self-esteem. Penile cancer is a rare neoplasia, particularly in developed countries. One of the world’s highest prevalence rates is found in India, at 3.32 per 100,000 inhabitants, and the lowest incidence is among Jewish men born in Israel, with rates close to zero [1]. In the United States, the prevalence is 0.2 cases for each 100,000 inhabitants, whereas in Brazil, the national incidence of penile cancer 4.6 per 100,000 inhabitants (with a wide variation of 2.9 to 6.8 cases per 100,000 depending on the region), one of the world’s highest rates of this neoplasia [2, 3]. The most common sites of penile cancer metastasis are the superficial and deeper nodes of the inguinal and iliac region. Patients have inguinal groin masses in 58% of cases, and 40% have positive metastasis, even in small cancers such as T1C and T2 [4]. Extended Inguinal lymphadenectomy is the most useful and commonly performed surgery for staging and to cure inguinal metastasis in penile cancer cases. Although it is a widespread technique, postoperatory complications often occur, such as cutaneous flap necrosis, lymphedema, and vascular lesions, including in the saphena magna ligature, with subsequent deeper venous thrombosis of the

Abstract: hepatitis c virus (hcv) genotypes and subtypes were determined in hemodialysis patients in the federal district, brazil, by sequencing of the 5' noncoding (nc) and nonstructural 5b (ns5b) regions. from 761 patients, 66 anti-hcv-positive samples were tested for hcv rna. all 51 hcv rna-positive samples by pcr of the 5' nc region were genotyped as genotypes 1 (90.2%) and 3 (9.8%). subtype 1a (82.3%) was the most prevalent, followed by subtypes 3a (9.8%), 1b (5.9%) and 1a/1b (2.0%). forty-two samples could be amplif??ied and genotyped in the ns5b region: 38 (90.5%) as genotype 1, subtypes 1a, and 8 (9.5%) as genotype 3, subtype 3a. for the 42 samples sequenced in both regions, the genotypes and subtypes determined were concordant in 100% and 95.2% of cases, respectively. two samples presented discrepant results, with the 5' nc region not distinguishing correctly the subtypes 1a and 1b. these findings indicate that the hcv genotype 1, subtype 1a, is the most prevalent among hemodialysis patients in the federal district, brazil.

Abstract: the aim of this study is to evaluate the safety of the use of a phytomedicine syrup (saratosse?) composed of several medicinal plants: mikania glomerata, mentha piperita, eucalyptus globulus and copaifera multijuga, along with honey and propolis to treat respiratory diseases. the clinical trial consisted of an open study with 26 adult volunteers of both sexes, who were given an oral dose of 15 ml of saratosse? for 28 consecutive days, four times a day. only volunteers who were found healthy after a clinical and physical examination were included. the laboratory tests included: hematological, biochemical and serological analysis. this evaluation was repeated after each week of treatment and seven days after the last administration. anova analysis (dunnett's test) showed a significant difference, albeit at low statistical level (p < 0.05). significant differences to the pre-study were not shown by hemoglobin, sgot, sgpt, creatinine and leukocytes analysis. laboratorial tests results were within their maximum and minimum reference values. on the whole the medicine was well tolerated. some side effects were related, which may or not be attributed to the phytomedicine. clinical, electrocardiographic and laboratory tests did not show any evidence of toxic signs in the organs and systems studied.

A comparison of evolutionary tracks for single Galactic massive stars

Physics , 2013, DOI: 10.1051/0004-6361/201322480
Abstract: In this paper, we compare the currently available evolutionary tracks for Galactic massive stars. Our main goal is to highlight the uncertainties on the predicted evolutionary paths. We compute stellar evolution models with the codes MESA and STAREVOL. We compare our results with those of four published grids of massive stellar evolution models (Geneva, STERN, Padova and FRANEC codes). We first investigate the effects of overshooting, mass loss, metallicity, chemical composition. We subsequently focus on rotation. Finally, we compare the predictions of published evolutionary models with the observed properties of a large sample of Galactic stars. We find that all models agree well for the main sequence evolution. Large differences in luminosity and temperatures appear for the post main sequence evolution, especially in the cool part of the HR diagram. Depending on the physical ingredients, tracks of different initial masses can overlap, rendering any mass estimate doubtful. For masses between 7 and 20 Msun, we find that the main sequence width is slightly too narrow in the Geneva models including rotation. It is (much) too wide for the (STERN) FRANEC models. This conclusion is reached from the investigation of the HR diagram and from the evolution of the surface velocity as a function of surface gravity. An overshooting parameter alpha between 0.1 and 0.2 in models with rotation is preferred to reproduce the main sequence width. Determinations of surface abundances of carbon and nitrogen are partly inconsistent and cannot be used at present to discriminate between the predictions of published tracks. For stars with initial masses larger than about 60 Msun, the FRANEC models with rotation can reproduce the observations of luminous O supergiants and WNh stars, while the Geneva models remain too hot.

Abstract: we report the case of a 60 years-old woman with autosomal dominant polycystic kidney disease (adpkd) that presented with headache and right complete ophthalmoplegia. the ct scan raised the possibility of a giant aneurysm of the right intracavernous internal carotid artery, confirmed by angiography. the patient underwent endovascular occlusion of parent vessel with detachable coils, then she presented interruption of headache and partial recovery of ptosis and ophthalmoplegia. we emphasize the relationship between adpkd and intracranial aneurysms. we also discuss the natural history and compare the therapeutic options for the management of giant aneurysms of the cavernous portion of the carotid artery.
