Pilot Anopheles gambiae full-length cDNA study: sequencing and initial characterization of 35,575 clones
We describe the preliminary analysis of over 35,000 clones from a full-length enriched cDNA library from the malaria mosquito vector Anopheles gambiae. The clones define nearly 3,700 genes, of which around 2,600 significantly improve current gene definitions. An additional 17% of the genes were not previously annotated, suggesting that an equal percentage may be missing from the current Anopheles genome annotation
Reproductive Performances of Local Pigs in West African Countries: A Review
The local pig is reared in all West Africa countries, and especially in small farms, playing so an important role in its preservation. This article reviews work done on reproductive performances of local pigs in West Africa. These performances focus on age at puberty, estrus and sex cycle, gestation length, prolificity, viability and growth before piglets weaning. Factors that can influence these parameters are included. Finally, the contribution of animal biotechnology to these performances improvement is discussed
Development of rat monoclonal antibodies to prevent hyperacute and acute rejection of vascularized xenograft in a pig-to-baboon model
Thèse de doctorat en sciences biomédicales (transplantation - immunologie) -- UCL, 200
Accommodation and antibodies.
Accommodation refers to the condition in which an organ transplant functions normally by acquiring resistance to immune-mediated injury (especially), despite the presence of anti-transplant antibodies in the recipient. This status is associated with several modifications in the recipient as well as in the graft, such as previous depletion of anti-graft antibodies and their slow return once the graft is placed; expression of several protective genes in the graft; a Th2 immune response in the recipient; and inhibition of the membrane attack complex of complement
The importance of large animal models in transplantation.
Animal models have been extensively used in transplantation research. However, animal experimentation is contentious and subject to legal and ethical restrictions. Most experiments are carried out on rodents, but crucial prerequisites for the development of safe pre-clinical protocols in biomedical research are needed through suitable large animal models. In transplantation particularly, large animal models have developed dramatically. This article provides an overview of the large animal models commonly used to evaluate organ transplant experiments and analyzes the specificity of several models in various situations such as induction of allospecific tolerance and xenotransplantation. The key determination that remains be addressed is the most appropriate species and strains to model human immune and physiological systems. Because of their phylogenetic and physiologic similarities to man, non-human primates play an increasingly important role in pre-clinical testing. Nevertheless, a number of studies have shown the pig to be a reliable large animal model for transplantation research, and the availability of genetically defined or modified pigs establishes a stronger position for pigs as a large animal model
Effects of oral supplementation with bovine colostrum on the immunity of weaned piglets
peer reviewe
A method combining enzymatic hydrolysis and in vitro fermentation to avoid in vivo trials to determine the nutritional value of forages and diets fed to Guinea pigs raised for meat production.
