Thousands of death in Africa and other developing nations are still attributed to trypanosomiasis. Excessive sleep has been associated with increased inflammation. We report herein, the synthesis, antitrypanosomal and anti-inflammatory activities of eight new carboxamide derivatives bearing
Trypanosoma cruzi proline racemases (TcPRAC) are the only eukaryotic proline racemases described so far. Except their role in the interconversion of free L- and D-proline enantiomers, parasite TcPRACs are involved in major T. cruzi biological pathways. These essential enzymes are implicated in the
The disorders of the gonadotropic axis have been studied during the course of a "chronic" african trypanosomiasis induced experimentally in rats inoculated by the variant Trypanosoma brucei brucei AnTat 1.1.E. The levels of serum and pituitary LH as well as serum testosterone and corticosterone have
Lymphocyte polyclonal activation is a generalized mechanism of immune evasion among pathogens. In a mouse model of Trypanosoma cruzi infection (American trypanosomiasis), reduced levels of polyclonal lymphocyte responses correlate with resistance to infection and cardiopathy. We report here the
Free serum amino acid pools of field voles, Microtus montanus, were determined over a 24 hr period, and compared to values obtained from voles infected with Trypanosoma brucei gambiense. The majority of amino acids in the control animals demonstrated a diurnal variation, peaking predominantly during
The protozoan parasite causing human African trypanosomiasis, Trypanosoma brucei, displays cysteine peptidase activity, the chemical inhibition of which is lethal to the parasite. This activity comprises a cathepsin B (TbCATB) and a cathepsin L (TbCATL). Previous RNA interference (RNAi) data suggest
In Trypanosoma brucei and related kinetoplastid parasites, transcription of protein coding genes is largely unregulated. Rather, mRNA binding proteins, which impact processes such as transcript stability and translation efficiency, are the predominant regulators of gene expression. Arginine
BACKGROUND
Dental caries is a major worldwide oral disease afflicting a large proportion of children. As an important host factor of caries susceptibility, saliva plays a significant role in the occurrence and development of caries. The aim of the present study was to characterize the healthy and
The eukaryotic protozoan parasite Trypanosoma brucei is the causative agent of human African trypanosomiasis. Polyamine biosynthesis is essential in T. brucei, and the polyamine spermidine is required for synthesis of a novel cofactor called trypanothione and for deoxyhypusine modification of
