Abstract: objective: demonstrate brain perfusion changes due to neuronal activation after functional electrical stimulation (fes). method: it was studied 14 patients with hemiplegia who were submitted to a program with fes during fourteen weeks. brain perfusion spect was performed before and after fes therapy. these patients were further separated into 2 groups according to the hemiplegia cause: cranial trauma and major vascular insults. all spect images were analyzed using spm. results: there was a significant statistical difference between the two groups related to patient's ages and extent of hypoperfusion in the spect. patients with cranial trauma had a reduction in the hypoperfused area and patients with major vascular insult had an increase in the hypoperfused area after fes therapy. conclusion: fes therapy can result in brain perfusion improvement in patients with brain lesions due to cranial trauma but probably not in patients with major vascular insults with large infarct area.

Abstract: this text makes an analisis about the cururu, a kind of singing challenge typical from countryside of state of s?o paulo, brazil. making a transcription of these challenges, it tries to point for questions about cururu's structure and performance, seen like a struggle between two singers that fight using singing words. at the same time, it sees like the cururu is a local updating of a social fact: the exchange. for this, it is possible to think about its characteristics in relationship with other kinds of singing challenges and making points about these social facts.

On the number of weighted subsequences with zero-sum in a finite abelian group
Abílio Lemos,Allan de Oliveira Moura
Mathematics , 2015,
Abstract: Suppose $G$ is a finite abelian group and $S=g_{1}\cdots g_{l}$ is a sequence of elements in $G$. For any element $g$ of $G$ and $A\subseteq\mathbb{Z}\backslash\left\{ 0\right\} $, let $N_{A,g}(S)$ denote the number of subsequences $T=\prod_{i\in I}g_{i}$ of $S$ such that $\sum_{i\in I}a_{i}g_{i}=g$ , where $I\subseteq\left\{ 1,\ldots,l\right\}$ and $a_{i}\in A$. The purpose of this paper is to investigate the lower bound for $N_{A,0}(S)$. In particular, we prove that $N_{A,0}(S)\geq2^{|S|-D_{A}(G)+1}$, where $D_{A}(G)$ is the smallest positive integer $l$ such that every sequence over $G$ of length at least $l$ has a nonempty $A$-zero-sum subsequence. We also characterize the structures of the extremal sequences for which the equality holds for some groups.

Abstract: Introduction: Vascular injuries are among the main mechanisms of death in trauma. In Brazil, the general surgeon is in charge of emergencies procedures in most hospitals, but many times these surgeons are not familiarized with more complex vascular surgical techniques that often require a vascular surgeon. Pará State is the most populated one in the Brazilian Amazon region and a single hospital with vascular surgeons permanently on call is available. Objectives: To evaluate demographic data on vascular trauma victims; to establish the mechanism, anatomic location, injury pattern and surgical techniques used to manage the vascular lesions treated at the Metropolitan Emergency Hospital; to ascertain associated non-vascular injuries and victim’s clinical outcome. Methods: Retrospective analysis of medical records of patients treated for vascular injuries from February 2011 to February 2013 at the institution in case. All arterial and venous injuries were analyzed. Patients who were not operated by the vascular surgery team, iatrogenic injuries and those who underwent primary or sustained traumatic amputation were excluded. Results: 173 cases; 95.95% were male; 54.90% were between 25 and 49 years; penetrating trauma mechanisms were found in 88.44%; lower limb was the most affected topography (41.50%); the most injured vessels were the superficial femoral and ulnar arteries (in 15.75% of cases each) and the superficial femoral vein (17.77 %); autologous vein graft was the most performed technique for arterial repair (36.57%) and ligature was performed in 85.00% of venous trauma; amputation rate was 15.60% and mortality rate was 6.35%. Conclusions: Vascular injuries occurred predominantly in men from 24 to 49 years old; penetrating mechanisms were most frequent; lower limb was the most affected topography; the most frequently injured vessels were the ulnar and superficial femoral arteries and the superficial femoral vein; complete vessel transection was the most common injury pattern; arterial trauma was most frequently treated by autologous venous graft interposition and ligature was performed for most of venous injuries; fractures were the most common associated lesions; the majority of patients recovered uneventfully, ischemic and infectious complications were the most frequent ones; deaths were caused by hypovolemic and septic shocks.

Abstract: trunk control - which is a basic motor ability to perform many functional tasks -is disrupted in most patients who have suffered a stroke. there are few foreign references and none in portuguese dealing with the quantitative assessment of trunk control. the aim of this study was to translate, verify intra- and inter-examiner reliability, validity and internal consistency of the brazilian version of the trunk impairment scale (tis). eighteen hemiparetic, post-stroke volunteers were evaluated by means of the fugl-meyer assessment scale, functional independence measure, berg balance scale (bbs), and functional ambulation classification; tis was apllied by three experienced physical therapists; retest was carried out 48 hours later. data analysis showed moderate intra-rater and an excellent inter-rater reliability (p<0.05), though low internal consistency (0.45). the only scale found to correlate with tis was bbs (r=0.491, p=0.038), comparison to the others having shown no statistical significance. the tis brazilian version thus proved a valid and effective measure of trunk deficits, having fulfilled reliability criteria; it is easy to apply, and may be said to be reproducible by neurology physical therapists.

Abstract: O Perímetro Irrigado Jabiberi, localizado no município de Tobias Barreto - SE, com área total de 362 ha é operado por gravidade que utiliza o método de irriga o por sulco, vem apresentando problemas de saliniza o em vários lotes. O presente trabalho teve por objetivo verificar através de análises químicas e físico-hídricas do solo o grau de saliniza o em dois lotes do perímetro, que se apresentam em processo de saliniza o. Os resultados indicaram que há grande quantidade de silte no solo e que a densidade global se eleva com a profundidade no perfil, bem como os valores da Velocidade de Infiltra o Básica (VIB) e Ko sofreram redu o nas áreas em que a condutividade elétrica (CE) apresentou maiores valores. é possível inferir que o NEOSSOLO FLúVICO, que ocupa a maior parte dos lotes do Perímetro, nesses lotes está em processo de saliniza o, apresentando em alguns pontos valores de CE quatro vezes superior ao limite para solos classificados como salinos.
Fibrodysplasia ossificans progressiva: case report
Arquivos de Neuro-Psiquiatria , 2000,
Abstract: Fibrodysplasia ossificans progressiva is a rare genetic disease characterized by widespread soft tissue ossification and congenital stigmata of the extremities. We report on a male child followed for ten years since the age of 3 years and 9 months, when the diagnosis was made. He was born with bilateral hypoplasic hallux valgus and ventricular septal defect, corrected by transsternal approach when 32 months old. Restriction of neck mobility followed and foci of ectopic ossification appeared. Four crises of disease exacerbation were treated with oral prednisone and/or other antiinflammatory drugs. Sodium etidronate 5 to 10 mg/kg/day was prescribed intermittently during about six years but was discontinued due to osteopenia. The disease course has been relentless, with severe movement restriction including the chest wall. A review showed few similar case reports in the Brazilian literature. We revisit the criteria for diagnosis and the essentials of management and treatment.

Abstract: Three groups of male rats were used: one was designated as control, one was sleep deprived for 96 h by the platform technique (SD-96h) and one was SD-96h followed by a 24-h recovery (rebound). In the first experiment, the animals were fed chow pellets (CPs); in the second, they received high-fat diet and in the third, they were fed a liquid diet (LD).We observed that SD induces energy deficits that were related to changes in feeding behavior and affected by the type of diet consumed. Regardless of the diet consumed, SD consistently increased animals' glucagon levels and decreased their leptin and triacylglycerol levels and liver glycogen stores. However, such changes were mostly avoided in the rats on the liquid diet. SD induces a wide range of metabolic and hormonal changes that are strongly linked to the severity of weight loss.The LD, but not the CP or high-fat diets, favored energy intake, consequently lessening the energy deficit induced by SD.Epidemiological studies have identified a relationship between a reduced number of sleep hours per day and increased body mass index, increased appetite, reduced leptin and augmented ghrelin levels [1-3], corroborating the view that inadequate sleep time is a risk factor for human obesity [2,4,5]. Paradoxically, sleep-deprived rats present a syndrome of increased feeding accompanied by weight loss [6]. Therefore, many studies have sought to identify the complex relationship between energy homeostasis and sleep to solve this paradox.Rechtschaffen's group characterized a long-term sleep deprivation (SD) response and found a progressive increase in both food intake and energy expenditure [7,8]. During SD, food intake of rats can be 80 to 220% higher than the pre-sleep-loss baseline [8-11]. Consistent with a higher drive for feeding, the hypothalamic expression of the anorexigenic peptide pro-opiomelanocortin is decreased, while levels of the orexigenics prepro-orexin and neuropeptide Y increase after SD [12,13].SD also induc
