Anatomical description of arterial segment of spleen of deer

The anatomosurgical segmentation of the arteries of the spleen was studied in 31 deer of the species Mazama gouazoubira and Blastocerus dichotomus by means of vascular injection with latex and vinyl acetate and radiographic examination. The arteria lienalis penetrated through the hilus lienis in 87% of the cases, whereas an extrahilar artery was present in the other cases. An extraparenchymal division of the lineal artery into two, three or four segmental arteries was observed in 74% of the cases. Anastomoses between intraparenchymal arterial branches were rare and of a reduced calibre.

Plantas medicinais: indicação popular de uso no tratamento de hipertensão arterial sistêmica (HAS)

The aim of this study is to investigate the spontaneous use of medicinal plants by volunteer patients in the treatment of hypertension and to determine the most used plants in this situation. Data were collected through a questionnaire and a semi-structured guided interview applied to patients from a health center in the Midwest region of the state of Sao Paulo, Brazil. Quantitative analysis identified a high number of hypertensive patients spontaneously using herbal treatment. The referred plants were identified by the Herbarium Botu and researched in the literature as to their therapeutic actions. The biggest mistake was observed in the misuse of the Bilberry for the treatment of hypertension, which reveals that health professionals and the community in general should be more careful. As a result we have published an informative booklet, with emphasis on hypertension concepts and on the use of medicinal plants as an alternative therapy method for this disease in order to provide scientific knowledge and scientific research evidence to this practice.

Influence of storage period of pieces in stiffness of pinus elliottii Glulam Beams

This study aimed to investigate the influence of storage time (0, 48 hours) of Pinus elliottii pieces and the tests to obtaining modulus of elasticity (static bending and transversal vibration) in glued laminated timber beams, produced with resorcinol based adhesive and 0.8 MPa compaction pressure. After pieces were properly prepared, part of them was used in immediate three manufacturing glulam beams, tested after adhesive cure, and part stored for 48 hours under a roof with a temperature of 25°C and relative humidity of 60% for subsequent manufacturing and testing three other glulam beams. Results of analysis of variance (ANOVA) revealed that the storage period was significant influence in modulus of elasticity obtained in static bending test (8% reduction from 0 to 48 hours). This not occurred with modulus of elasticity obtained by transversal vibration test (no significant influence). ANOVA results showed equivalence of means in both test procedures. New researches ire needed to better understand the investigated phenomenon, using new wood species, other storage conditions and a great number of samples.

Influence of nonlinear stiffness on the dynamics of a slender elastic beam under torsional oscillations

This study focuses on analysing the effects of nonlinear torsional stiffness on the dynam-ics of a slender elastic beam under torsional oscillations, which can be subject to helical buckling.The helical buckling of an elastic beam confined in a cylinder is relevant to many applications. Someexamples include oil drilling, medical cateters and even the conformation and functioning of DNAmolecules. A recent study showed that the formation of the helical configuration is a result of onlythe torsional load, confirming that there is a different path to helical buckling which is not related tothe sinusoidal buckling, stressing the importance of the geometrical behaviour of the beam. A lowdimensional model of an elastic beam under torsional oscillations is used to analyse its dynamical be-haviour with different stiffness characteristics, which are present before and after the helical buckling.Hardening and softening characteristics are present, as the effects of torsion and bending are coupled.With the use of numerical algorithms applied to nonlinear dynamics, such as bifurcation diagramsand basins of attraction, it is shown that the nonlinear stiffness can shift the bifurcations and inducechanges in the stability of the desirable and undesirable solutions. Therefore, the proper modellingof these stiffness nonlinearities seems to be important for a better understanding of the dynamicalbehaviour of such beams.

Influence of the number of load cycles to obtain the stiffness properties of angico preto (Anadenanthera macrocarpa) wood specie

The tests used to obtain the stiffness properties of wood are made with two loading cycles, as defined by the Brazilian standard ABNT NBR 7190 (Design of Timber Structures). However, the possibility of reducing the number of cycles allows decrease the operating time of the machine, resulting in reduced spending on electricity used during the tests. This research aimed to investigate, with the aid of the analysis of variance (ANOVA), the influence of the use of three load cycles to obtain the modulus of elasticity in compression parallel to grain (Ec0), in tensile parallel to the grain (Et0), in bending (Em) and in compression perpendicular to the grain (Ec90) of Angico Preto (Anadenanthera macrocarpa) wood specie. For the number of cycles and stiffness were manufactured 12 samples, totaling 144 specimens. The results of the ANOVA revealed statistical equivalence between the stiffness properties for both load cycle numbers evaluated, indicating that it is possible to carry out the tests with a single charge cycle, allowing savings in time and energy in the operation of the equipment.

Estado nutricional e ocorrência de hipertensão arterial e de diabetes em idosos residentes e não residentes em instituições geriátricas

The aging process involves challenges in meeting social needs, economic and health. Physiopathological changes and socio-economic predispose the elderly population at nutritional risk. The monitoring of nutritional status predict some complications of obesity or malnutrition, and is a tool for health care. The objective to know the nutritional status and risk of chronic diseases of the elderly in geriatric institutions and volunteers. The elderly population of 3 geriatric institutions (n=122) and non-institutionalized elderly (n=75) were evaluated. The body mass index was evaluated according to Nutrition Screening Initiative. For waist circumference, was used the World Health Organization criteria. For statistical analysis, chi-square was used. A high proportion of obesity (46%) was observed. The underweight affects 4% and 20% of noninstitutionalized and institutionalized, respectively. The frequency of the risk of diseases associated with obesity was higher among non-institutionalized. Hypertension affects more than 50% of the elderly. The nutritional status was different between the two situations, with high incidence of overweight and visceral adiposity, in volunteers, and wasting among institutionalized. The data emphasize that it is necessary special attention and appropriate measures to prevent morbidity and mortality and to improve quality of life.
