A bobine cDNA encoding erythropoietin (Epo) was isolated by polymerase chain reaction (PCR) amplification and screening of a bovine kidney cDNA library. The sequenced cDNA has a length of 1312 bp and an open reading frame that encodes a predicted 192-amino-acid (aa) protein, including a putative ...

Infection with African trypanosomes causes the diseases sleeping sickness in humans and nagana in cattle in sub-Saharan Africa. Suppression of cellular immune responses is a feature of trypanosomiasis in bovine, human, and murine hosts. Some aspects of immunosuppression in the murine model are me...

Nitric Oxide synthesis is depressed in Bos indicus cattle infected with Trypanosoma congolense and Trypanosoma vivax and does not mediate T-cell suppression
T-cell-mediated immune responses to defined antigens of Trypanosoma congolense were measured in cattle undergoing primary infection. The antigens used were the variable surface glycoprotein and two invariant antigens, a 33-kDa cysteine protease (congopain) and a recombinant form of a 69-kDa heat-...

According to studies in human and mouse species it is apparent that both CD40 ligand and tumor necrosis factor alpha (TNF alpha) are members of a novel family of cytokines, referred to as the TNF - superfamily. This article reports the cloning of the cattle CD40 lignad and cattle TNF alpha, and s...

The objective of this study is to better understand the complexity of deforestation processes in southern Cameroon by testing a multivariate, spatial model of land-cover change trajectories associated with deforestation. The spatial model integrates a spectrum of independent variables that charac...
The authors used a configurational comparative approach, the Qualitative Comparative Analysis (QCA), to study multiple causal interactions characterizing deforestation in the Brazilian Amazon. Their data set is based on seven local case studies at three time periods. Results reveal a limited numb...

Geographic information system techniques were used in combination with remote sensing data to define the net commercial value of standing timber at two sites (Batouri and Bertoua) in the East province of Cameroon. Observed forest cover modifications for the two sites were assessed in relation to ...

The Development of vaccine against the African trypanosomiasis passes through the identification process of invariant component. This process targets the prevention of infection or diseases related to it. Immunity suppression in almost a universal feature of infection and represents probably an e...
