The aim of the study was to evaluate the influence of glucocorticoids on vital parameters of full-term and preterm lambs from birth to 48 hours of life. Four experimental groups were formed: NDG (normal delivery group - lambs vaginally delivered, n=15, average of 146-day gestation); NDEXG (normal delivery with dexamethasone group - lambs vaginally delivered whose mothers received 16mg of dexamethasone at 141 days of gestation, n=8, average of 143-day gestation); PRE (premature lambs born by cesarean section at 138 days of gestation, n=10) and PREDEX (premature lambs born by cesarean section at 138 days gestation, whose mothers received 16mg of dexamethasone two days before, n=9). Heart and respiratory rates had variations during the observation period, with the highest mean values in the groups of normal deliveries (NDG and NDEXG). Rectal temperature decreased in all groups in the first 60 minutes of life, with the lowest mean values in premature lambs (PRE and PREDEX) and the Apgar score was higher in animals delivered at normal gestational time. Preterm lambs had lower vitality and chance of survival, however, lower mortality rate was observed in offspring of ewes that received dexamethasone two days before surgery.

In Brazil, phosphorus availability is one factor that that more limit yield of upland rice under rainfed system. Then, better understanding of cultivars development at phosphorus soil fertilization is very important in the production systems making this more sustainable. The objective was to evaluate the influence of phosphorus doses applied to the soil over the root length, root and shoot dry matter, concentration and content of macronutrient and zinc in shoot and root as well as the efficiency of nutrient uptake per meter root of upland cultivars of intermediate and modern groups. The experiment was carried out in greenhouse conditions in a completely randomized design in factorial scheme 4 x 4. Treatments were four levels of P fertilization applied at the soil (0, 50, 100 and 200 mg dm(-3) of P) and four upland rice cultivars (Maravilha - modern group, IAC-201, IAC-202 and Carajas - intermediate group). There is increase in phosphorus availability in the soil with increasing levels of P fertilization. Under low phosphorus availability, cultivars of the intermediate group have better shoots and root system development in relation to the modern cultivar group. Level of phosphorus affected nutrients contents in shoots and root system of upland rice cultivars. The increasing phosphorus fertilization increased uptake of nutrients per meter of root; and although under higher phosphorus availability there was a greater root growth, in low phosphorus availability root growth was greater at the expense of shoot growth.

The interview has been a widely used procedure of research in humanities. Despite the frequent use, researches are not always supported in the literature on research methodology. The aim of this study was to analyze how the interview was used in dissertations and theses in a graduate Program in Education at a university in Sao Paulo state. This study examined 167 final papers developed in to period of five years. Variables focused were: justification for the use of interview, type of interview used, guide elaboration and adaptation, kind of analysis, among others. The results showed that it is still necessary to incorporate the contents of the research methodology underlying the use of the interview to achieve the scientific rigor for this procedure.

Technology advances and scientific studies in Neonatal Intensive Care Units (NICU) have contributed significantly to reduce mortality and morbidity of at-risk newborns (NB). However, they are more likely to present neurological and/or developmental psychomotor delay with neurological and sensory alterations. Therefore, proposals for neonatal intervention were developed with the aim of protecting the baby and offering appropriate incentives to minimize the effects of hospital intervention. To this end, programs of protective measures such as the Kangaroo Mother Care (KMC) were developed. Given the relevance of the issue described, this systematic review critically appraises articles from the national and international literature, published in recent years (from 2000 to 2011), that describe whether the KMC can be a protective factor for the development of writing in premature infants. The textual search was conducted using the Virtual Health Library (VHL), a website that covers publications worldwide, allowing access to articles from health science, including LILACS, IBECS, MEDLINE, Cochrane Library and SciELO, as database. The findings revealed that infants who participated in the KMC program showed improvements in their development and that factors such as low-birth-weight prematurity and learning disorders have close relationship with the onset of motor impairments and changes in psychomotor development. The findings showed no articles describing the KMC as a protective factor for the incidence of dysgraphia. Thus, we emphasize the importance of conducting further studies on these topics.

The Assistive Technology makes the lives of people without disabilities more practical, but for people with disabilities it can make things possible. For these individuals can provide the conditions, making their limitations are not obstacles to their social and personal empowerment, and may contribute to their effective participation in tasks that were previously impossible, such as remaining seated correctly. A segment on which the necessary assistive technology works, is the adaptation of furniture such as chairs, tables, chairs-to-wheels for individuals with disabilities, as well as cerebral palsy. The study aimed to conduct a survey and brief description of theses and dissertations produced in Brazil on furniture adapted for students with cerebral palsy. We made searching in databases of libraries of major universities and federal state national banks, theses and dissertations. Nine studies were selected for description. It was concluded that there is a considerable array of professionals, both in engineering as the field of rehabilitation, to contribute in the adaptation, creation and even the manufacture of furniture for children with cerebral palsy and that the securities most studied are the chairs and their components.

The benefits of proper nutrition and analgesia are closely linked when it comes to animals that are suffering from any illness and are hospitalized. In patients who are ill or under the stress of hospitalization, increase secretion of glucagon, catecholamines, cortisol and growth hormone antagonize the effects of insulin, leading to hyperglycemia and degradation of tissue proteins to provide substrate for gluconeogenesis. These changes result in loss of lean body mass, reflecting negatively on tissue repair processes, immune response and prognosis. Likewise, the pain induced by noxious stimulation can lead to protein catabolism, stress, immunosupression, delayed wound healing and acceleration of disease processes. This review confirms the nutrition and pain control importance in hospitalized patients, showing their physiological benefits and reduction in hospital stay when the clinician understands these benefits and the animals are treated with such care

A síndrome metabólica é um mal que, segundo projeções, poderá no ano de 2010, acometer de 50 a 75 milhões de pessoas somente nos Estados Unidos. Dessa forma, é de grande interesse a implementação de procedimentos mais eficazes para prevenção e tratamento desta doença. Uma vez que existem limitações nas pesquisas com seres humanos, torna-se necessário o desenvolvimento de modelos experimentais apropriados ao estudo desta questão. Na busca de um modelo experimental adequado ao estudo do papel do exercício na prevenção e no tratamento da síndrome metabólica, o presente estudo analisou o perfil metabólico e a capacidade aeróbia de ratos mantidos com dieta rica em frutose, substrato que tem sido associado à síndrome metabólica, na vida intra-uterina e pós-natal. Foram utilizadas ratas adultas (90 dias) da linhagem Wistar, alimentadas durante a prenhez e a lactação com dois tipos de dieta: balanceada (AIN-93G) e rica em frutose (60% de frutose). Durante a amamentação, os filhotes foram distribuídos em ninhadas pequenas (4/mãe) ou adequadas (8/mãe). Após o desmame, manteve-se as mesmas dietas até os 90 dias, quando foram analisados: tolerância à glicose (teste de tolerância à glicose), sensibilidade periférica à insulina (teste de tolerância à insulina); capacidade aeróbia (determinação da máxima fase estável de lactato em natação), conteúdo pancreático de insulina; peso e concentração de lipídios totais no tecido adiposo de diferentes regiões e concentrações séricas de glicose, insulina, triglicerídeos, colesterol total, colesterol LDL, colesterol HDL. Constatou-se que a dieta rica em frutose conduziu os animais a resistência à insulina. O grupo FP apresentou dislipidemia, com aumento nas concentrações séricas de colesterol total e triglicerídeos, mostrando que o modelo animal avaliado é potencialmente interessante para o estudo da síndrome metabólica.

The beneficial effects derived from the nutritional support in human patients and experimental animal models include the improvement of immune function, repair of wounds, answer to the treatment, time of recovery and survival. In front of these benefits, we end up alienating the nutritional needs of hospitalized patients, especially those with clinical or surgical affections threatening. The objective of the nutritional support is to indicate the importancea and the proportions of energy and nutrients that the patient can use with the maximum effectiveness. The majority of hospitalized patients do not have voluntary food intake adequate to meet even the minimal nutritional needs. It is often perceived that lack of adequate food intake, will have serious impact on the patient’s clinical outcome. The nutritional assessment will help determine which route of feeding will be the safest, most effective and best tolerated by the patient. Diet choice is based on which of the patient’s problems can and should be addressed with nutrition and the feeding access available
