Biological Behaviour of Murrah Water Buffaloes

Modest but constant and progressive is the importance that buffaloes are achieving at the scientific’s, producer’s and consumer’s societies. Feeding behaviour is a continuous act in animals. Motivation is a reversible process of the brain induced by external factors. So, consumption tends to be continuous until another stimulus such as satiation becomes dominant. The majority of large domestic animals is fed “ad libitum”. This originates different situations when they are over or underfed. That is the situation that makes the cyrcadian rithm an important tool to be used in order to achieve maximum gains in rangelands. For half a year, 3 groups of 10 animals each (2 males and 8 females) were observed recording their biological behaviour. Data analysis showed that grazing activity occurred from 7 to 10 a.m. and from 5 to 8 p.m. setting the maximum grazing period of six hours per day as long as forage is available. The informations allow to adopt strategies for further feeding studies

A Experiência de Um Ano na Monitorização de Estenose Intracraniana nas Crianças com Anemia de Células Falciformes (Depranocitose) por Ecodoppler Transcraniano

O Laboratório de Neurossonologia do Hospital de S. José do CHLC, EPE propôs-se avaliar os registos velocimétricos obtidos na realização de Ecodoppler Transcraniano aos doentes em idade pediátrica portadores de Drepanocitose, durante o ano de 2010, verificando-se uma baixa incidência de estenose intracraniana

Personality as a Predictor of Disability in Multiple Sclerosis.

As personality changes and personality disorders are frequently observed in multiple sclerosis (MS), personality may be a prognostic factor for this disease. The present study investigated the influence of personality on disability, progression, and treatment adherence in MS. Personality was assessed in 41 patients with Relapsing-Remitting MS (30 females; mean age = 42.63 years) using the NEO Personality Inventory-3rd edition. Disability was measured with the Expanded Disability Status Scale, and treatment adherence information was collected from the Swiss MS Cohort. Correlation, multiple linear and partial least square regressions were performed to examine relations between personality, disability, and treatment adherence in MS. After accounting for age and time since disease onset, our analysis revealed that Neuroticism (β = 0.32, p = 0.01) and its Vulnerability facet (β = 0.28, p < 0.05) predicted greater disability, whereas Extraversion (β = -0.25, p = 0.04) and its Activity facet (β = -0.23, p < 0.05) predicted milder disability. Regarding disability progression, correlational analysis revealed that it was negatively correlated with Extraversion (r = -0.44, p = 0.02) and the Feelings facet of Openness (r = -0.41, p = 0.03), but regressions failed to highlight any predictive links. No significant results could be demonstrated for treatment adherence. Overall, our study showed that some personality traits can impact disability in MS, indicating that these should be considered in clinical practice, as they could be used to adapt and improve patients' clinical support

Alguns dados referentes ao estudo parasitológico e anatomopatológico de duas linhagens de Schistosoma mansoni Sambon, 1907

An experiment was carried out in order to determine differences in the pathology of two S. mansoni strains, one from the state of Minas Gerais (Belo Horizonte) and the other from the State of S. Paulo (S. José dos Campos), Brazil. Mice were infected with both strains under experimental conditions and the comparative study of these animals showed significant differences as regards pathology of the tissue lesions. The Belo Horizonte strain showed a higher level of pathogenicity when compared to the S. José dos Campos one.Foi estudada a ação patogênica das linhagens de Schistosoma mansoni dos municípios de Belo Horizonte, MG e de São José dos Campos, SP (Brasil) observando maior capacidade patogênica da linhagem do primeiro, nas condições da experiência

Micropropagação de Pinus caribaea Morelet var. hondurensis Barr. & Golf.

O setor florestal brasileiro conta atualmente com uma área de 7,84 milhões de hectares de florestas plantadas, o que representa cerca de 1% do território nacional. No ano de 2016 sua arrecadação representou 6,2% do PIB Industrial no País (Ibá, 2017). A área de florestas plantadas é responsável pela produção de 91% de toda a madeira produzida para fins industriais no País. Em termos de produtividade, em 2016 o Brasil liderou o ranking global, com uma média anual de 35,7 m³/ha para os plantios de eucalipto e 30,5 m³/ha aos plantios de pinus, principais espécies plantadas (Ibá, 2017). No entanto, a demanda por commodities e bioenergia está em franca expansão. Projeções indicam que, em 2050, serão necessários 250 milhões de hectares adicionais de florestas plantadas no mundo (Ibá, 2017), o que demonstra a necessidade de aumento de área e, ou produtividade por área plantadabitstream/item/214568/1/CT-447-1778-final2.pd

Distribuição das lesões esquistossomóticas extra-hepáticas em camundongos infectados pelas linhagens BH e SJ do Schistosoma mansoni

The distribution of schisiosomotic granulomae in the spleen, lungs, kidneys, heart, and intestines of mice infected by BH and SJ strains of S. mansoni was studied. No great difference was found in the distribution of granulomae of the two strains; however, the number of lesions caused by the BH strain was greater in the spleen and the lungs.Foi estudada a distribuição dos granulomas esquistossomóticos no baço, pulmões, rins, coração e intestinos de camundongos parasitados pelas linhagens BH e SJ de S. mansoni. Verificou-se que a distribuição de granulomas produzidos pelos esquistossomos das duas linhagens é semelhante, sendo que a linhagem BH produziu número significativamente maior de lesões no baço e nos pulmões

Fluorescence polarization and rheological studies of the poly(N-vinyl-2-pyrrolidone) hydrogels produced by UV radiation

Abstract Poly(N-vinyl-2-pyrrolidone) hydrogels produced by direct ultraviolet irradiation of PVP aqueous solution leads to crosslinking through pyrrolidinone moiety photolysis. Generally, hydrogel physical properties, like crosslinking density, pore size, swelling capacity, storage and loss moduli are obtained by swelling and rheological tests. However, relations between anisotropy obtained by fluorescence polarization studies and these properties have not been addressed for hydrogel systems. In this work we show that there is a correlation between the data obtained from anisotropy and rheological experiments, since both of them are related with crosslinking density of the hydrogels. These results reveal that fluorescence polarization spectroscopy is a promising tool for understanding the structure of hydrogels.
