With aging process, there is a natural biological decline that eventually may lead to a functional and cognitive decrease. It is important that older people preserve these functions so they can live an independent life. Some declines in old people who attend Geriatric Day-Care tend to be more severe and recurrent. The Square Stepping Exercise (SSE) is a program created by Shigematsu & Okura (2006), in order to improve the balance of its practitioners, thereby decreasing the risk of falls. It is also believed that the SSE stimulates cognition, and thus, executive functions. The present study, with a longitudinal design, evaluated the effects of SSE in balance performance and executive functions of elderly from the “Centro-Dia do Idoso Padre Casagrande” from Rio Claro – SP. A group of 15 people (GT, n = 15), which performed a four month SSE intervention, and a control group (GC; n = 17) answered the following evaluations.: Questionnaire Registration Data and Anamnesis, Questionnaire Baeck Modified for Elderly, Mini-Mental State Examination, Modified Card Sorting Test, Geriatric Depressive Scale, Questionnaire Pfeffer for Instrumental Activities, Berg Balance Scale and Time Up and Go Test. Although significant improvements have not been observed in GT, the results showed a decline in instrumental activities performance in GC, as well as maintenance in executive functions and balance, and also an improvement in depressive symptoms in GT. This way, Square Stepping Exercise can be considered an activity that helps maintaining functional capacity, among them balance, and executive function in elderly people.

Atualmente, as pesquisas acadêmicas e industriais não estão voltadas apenas para a descoberta de novos fármacos, mas também para novas maneiras de administração de medicamentos pretendendo obter melhores ações farmacológicas alem de reduzir efeitos colaterais. Partindo deste pressuposto, estudos demonstram que inúmeras moléculas podem ser incorporadas a polímeros híbridos orgânico-inorgânico preparados pelo processo sol-gel, assim pretende-se estudar a possibilidade de sua aplicação no desenvolvimento de um dispositivo de liberação controlada de fármacos na forma de implantes subcutâneos. As matrizes hibridas para serem implantadas devem, necessariamente, ser estéreis. Para isto este trabalho analisa a interação entre o processo de esterilização e uma provável alteração estrutural nestes polímeros. A esterilização por calor úmido em autoclave e a esterilização por radiação gama foram escolhidas para analisar a correlação entre alteração estrutural do hibrido e o processo de eliminação de microorganismos. Outro aspecto que levamos em consideração foi a melhora das características mecânicas das matrizes poliméricas confeccionadas com poli óxido etileno de peso molecular 1900 (POE 1900) e poli óxido propileno de peso molecular 400 (POP 400). Para serem implantadas estas matrizes devem estar uniformes, e não podem trincar ou quebrar antes ou após a implantação. Considerando estes fatores foi adicionado as amostras um agente plastificante, o álcool polivinílico (PVA), na tentativa de melhorar estas características

The consumption of fat related to the incidence of diseases has motivated the development of food with less or even no fat. However, fat is important for the full functioning of the human body and sensory characteristics of food. Therefore, making food with little or no fat and at the same time maintaining the desired quality is a challenge for the industry. Fat substitutes were created to achieve this objective. Fat substitutes can be more effective in their applications when mixtures of different types of them are used. The number and variety of these ingredients are still growing, expanding options of choice when a fat substitute is required in a certain type of food. Considering the importance of fat substitutes nowadays, this paper presents an overview of functions and implications of fats in the human body and food, the terminology used to refer to fat substitutes, the categories of different types of fat substitutes available in the market and their applications in dairy products.

Employing the method of least squares and quadratic B-spline polynomials, different statistical models were tested to identify the most appropriate to model the mean trajectories of live weight and carcass yield of Nile tilapia (Oreochromis niloticus). Data of live weight (8,758) and carcass yield (2,042) of tilapias with ages between 106 and 245 days were obtained from 72 families derived from 36 males and 72 females. The sex and tank variables were considered as classificatory and the coefficients of quadratic polynomials B-spline of two to five intervals of the same size were used as covariables. According to most fit criteria used, the models with quadratic B-spline polynomial with five intervals of the same size presented the best adjustments. The increase in number of intervals of B-spline polynomial improved the fit of the polynomials to the data. The inclusion of classificatory effects from sex, tank, the interaction of these effects and the quadratic polynomial B-spline nested in this interaction indicated that, over time, each sex, grown in different tank, presented different mean trajectory, necessitating the inclusion of nesting time in the interaction sex x tank in order to avoid the under or overestimation of breeding values of the selection candidates in breeding programs of this species.
