Evaluation of the proteomic profiles of ejaculated spermatozoa from Saanen bucks ( ).

The Saanen goat breed has been widely explored in breeding programmes; however, there are few reports about the breed's genetic and molecular composition. Thus, this study aimed to characterize the proteomic profile of spermatozoa from Saanen breeding goats. Five breeding animals with proven fertility were selected, the spermatozoa were collected, and the protein was extracted.

Diversity of ejaculated sperm proteins in Moxotó bucks ( ) evaluated by multiple extraction methods.

This study aimed to develop protocols for the extraction of sperm proteins from Moxotó goats () and to compare the resulting proteomic maps. The sperm proteins were isolated using an extraction buffer containing 7 M urea and 2 M thiourea, 20 mM DTT, and one of the following detergents: 1% or 4% CHAPS; 1% or 4% SDS; 1% or 4% Triton X-100; or a combination of CHAPS and SDS. The 1-DE and 2-DE profiles of the isolated proteins revealed that the various isolation methods were efficient.

Knowledge and attitudes towards dementia among final-year medical students in Brazil.

Objective:: Among all countries, Brazil is expected to have the sixth largest elderly population in 2025. Dementia syndromes are prominent among aging-related diseases. Despite the necessity of and curriculum for training in geriatric medicine to make recommendations on an approach to this theme, adequate training appears to be infrequent.
