In vivo and in vitro heat shock proteins gene expression in cattle.

The main purpose for this study was the quantification of the heat shock proteins HSPA1A and HSP90AA1, in cow lymphocytes, when subjected to heat stress directly - in vivo, or indirectly - in vitro. The aim was to identify differences between HSP expression in vitro and in vivo. The experiment was conducted in the Biometeorology and Ethology Laboratory of FZEA-USP. Were used three female Holstein Frisian, which...

National post hospital care project and length of hospitalization of patients w...

INTRODUCTION: The National Post Hospital Care Project was created to provide a continuity of care after hospitalization or to functionally dependent people. Currently there is a great difficulty in the integration of patients. The objective of this paper is to compare the impact of the referral to the Project versus being discharged home, in the length of stay of stroke patients between 2010 and 2011. MATERIAL ...

What Do Cattle Prefer in a Tropical Climate: Water Immersion or Artificial Shade?

Animal performance is affected by high air temperature and it is known that shade reduces the absorption of radiant temperature, and water for immersion facilitates heat loss. This study intends to find preferences of resources that contribute for the well-being of cattle and how they alterdaily behaviour. During summer, six Caracu and six Red Angus bulls were submitted to two different treatments: availability...

Influence of season on plasmatic cortisol and IGF -I in dairy cows under therma...

Objectives: Access to evaporative cooling system can increase production in dairy cows due to improve thermal comfort. The aim of this study was to evaluate the impact of ambient temperature on thermoregulation, cortisol and IGF-I, and determine the efficiency of evaporative cooling system on the physiological responses in different weather patterns. Materials and Methods: 24 Holstein cows were housed in two gr...

Behavioral aspects of Caracu and Red Angus cattle breeds in a pasture with shad...

The shade is an important resource in the extensive production systems in tropical regions. The aim of this study is to understand through behavioral analysis, the preferences of animals for resources for environmental protection. The experiment was conducted in the Biometeorology and Ethology Laboratory of FZEA-USP. Six male of Caracu and Red Angus cattle breeds were used. The animals were submitted to 2 diffe...

INFLUENCE OF SHADOW AVAILABILITY ON SPERMATIC MORPHOLOGY OF BRAHMAN BULLS [Bos ...

Under heat stress conditions, testicular degeneration can occur, even on zebu animals. Therefore, the aim of this work was to verify the occurrence of any possible effect of shadow availability on pasture on spermatic morphology of Brahman Bulls on Brazil Southeast. Five animals were allocated on pasture with shadow availability, and five bulls were allocated on pasture without any kind of shadow. No difference...

Mecanismos de transferência de massa na desidratação osmótica de goiaba em solu...

O objetivo deste trabalho foi avaliar o efeito da concentração de soluções de sacarose, sucralose e açúcar invertido sobre a cinética da desidratação osmótica de pedaços de goiaba. Frações de 1/12 do fruto foram imersas em soluções de sacarose a 0,5 e 0,4 g mL-1; de sacarose a 0,3 g mL-1 + sucralose a 0,2 g L-1 e em xarope de açúcar invertido, a 50 ºC, por 2 h, sob agitação de 60 min. A solução de açúcar invert...

Níveis de metionina + cistina digestíveis em rações para poedeiras no pico de p...

Avaliaram-se os efeitos de níveis de aminoácidos sulfurados digestíveis (AASD) sobre o desempenho e a qualidade interna e externa de ovos de 360 poedeiras de 25 a 41 semanas de idade. Foram formuladas seis dietas experimentais: cinco continham 0,578; 0,636; 0,694; 0,752 ou 0,810% de AASD, e em uma o nível de AASD foi o usualmente recomendado, cada tratamento com cinco repetições de 12 aves, em quatro períodos d...

Limb-girdle muscular dystrophy in a Portuguese patient caused by a mutation in ...

Limb-girdle muscular dystrophy 2G is caused by mutations in the telethonin (TCAP) gene in chromosome 17q11-12. This rare form of hereditary muscle disease was originally described in Brazilian patients and was recently identified in Chinese and Moldavian patients. We present the first Portuguese patient with a limb-girdle muscular dystrophy caused by a mutation in the TCAP gene. A Caucasian male, 50 years old, ...
