Autor: Giovanni Francisco Rabelo, Graham W. Horgan, Adilson Machado Enes, D. Miron, Roberto A. Braga, J. B. Barreto Filho

Publikováno v: Computers and Electronics in Agriculture. 58:123-132

Biospeckle analysis has been used as a tool to analyse biological activity with successful results in areas such as fruits, seeds and animal reproduction. These results use well-known image analysis methodology to treat the data with a second order s

Brazilian Journal of Medical and Biological Research, Volume: 34, Issue: 5, Pages: 663-667, Published: MAY 2001

The structure-function relationship of interferons (IFNs) has been studied by epitope mapping. Epitopes of bovine IFNs, however, are practically unknown, despite their importance in virus infections and in the maternal recognition of pregnancy. It ha

Prevalence of antibodies to bluetongue, bovine herpesvirus 1 and bovine viral diarrhea/mucosal disease viruses in water buffaloes in Minas Gerais State, Brazil

Autor: A P, Lage, R S, Castro, M I, Melo, P H, Aguiar, J B, Barreto Filho, R C, Leite

Publikováno v: Revue d'elevage et de medecine veterinaire des pays tropicaux. 49(3)

A serological survey to detect water buffaloes with antibodies to bluetongue virus (BTV), bovine herpesvirus 1 (BHV 1) and bovine viral diarrhea/mucosal disease virus (BVD/MDV) was performed in Minas Gerais State, Brazil. Precipitating antibodies aga

Erythrophagocytosis in the caprine trophoblast

Autor: J.S. Andrade, A.P. Marques Jr., J. B. Barreto Filho, Renato L. Santos

Publikováno v: Theriogenology. 46(6)

The mechanism of iron transfer by extravasation of maternal blood in the maternal-fetal interface and the subsequent phagocytosis of the erythrocytes by the trophoblast cells was described in ovine, bovine and other species. This research was perform

42 SEMEN FERTILITY OF THE BULL EVALUATED BY SECOND-ORDER STATISTICS

Autor: M. O. G. Nogueira, J. B. Barreto Filho, Giovanni Francisco Rabelo, Roberto A. Braga, R. S. Macedo, M. V. C. Ferraz, T. F. Silva

Publikováno v: Reproduction, Fertility and Development. 22:178

The biospeckle (BSL) is based on the incidence of laser light upon active biological materials, followed by analysis and manipulation of secondary images, and then, application to those images of a second-order statistics technique called the inertia

26 SPERM MOTILITY DECREASING AND SEMEN FERTILITY IN THE BULL EVALUATED BY BIOSPECKLE

Autor: Roberto A. Braga, Giovanni Francisco Rabelo, J. B. Barreto Filho, R. S. Macedo

Publikováno v: Reproduction, Fertility and Development. 22:170

Sperm motility decreasing in a semen sample over time is an indirect approach to assess spermatozoa viability and should be related to the ejaculate fertility. The biospeckle (BSL) is an interacting phenomenon between laser light and biological speci

22 IN VITRO FERTILITY ESTIMATES USING SPERM KINETICS VARIABLES AND CONCEPTION RATES IN BEEF HEIFERS

Autor: Giovanni Francisco Rabelo, Roberto A. Braga, T. F. Silva, J. B. Barreto Filho, M. V. C. Ferraz, R. Previdelli, R. S. Macedo

Publikováno v: Reproduction, Fertility and Development. 22:169

Sperm motility is a physical parameter evaluated in semen samples of the bull and is thought to be related to the fertility in the male. Despite being a characteristic of simple and fast evaluation, motility estimates involve subjective components wh
