Breeding objectives of Brangus cattle in Brazil.

Our goal was to define a breeding objective for Brangus beef cattle in Brazil. Bioeconomic models were produced and used to estimate economic values (EVs). The scenarios simulated were typical full-cycle beef production systems that are used in tropical and subtropical regions.

What Is the Best Way to Prepare A Buccal Mucosa Graft for Urethroplasty? A Histology-Based Preliminary Report.

Purpose: To evaluate the histological characteristics of buccal mucosa samples prepared using different dissection techniques.

Methods: The buccal mucosae harvested from 9 men submitted to a substitution urethroplasty were used in this study. Biopsy specimens of buccal mucosae were grouped according to the macroscopic appearance after dissection: Group 1 - yellowish appearance (minimal dissection), Group 2 - whitish appearance (more aggressive dissection), and Group 3 - translucent appearance (ultra-aggressive dissection).

Histomorphometric comparison of the human, swine, and ovine collecting systems.

The ovine kidney has been recently determined to be a better model than the swine kidney for the study of collecting system healing after partial nephrectomy. However, there is no histological study comparing the collecting systems of these species. To compare human, swine, and ovine collecting systems using histomorphometry.

Testicular Morphology and Spermatozoid Parameters in Spontaneously Hypertensive Rats Treated with Enalapril.

Purpose: We evaluated testicular morphology and spermatozoid parameters in spontaneously hypertensive rats treated with enalapril.

Materials And Methods: Spontaneously hypertensive rats were assigned to a hypertensive nontreated group and a hypertensive enalapril treated group. Wistar-Kyoto normotensive rats served as controls.
