Due to drawbacks of live attenuated vaccines, much more attention has been focused on screening of Brucella protective antigens as subunit vaccine candidates. Brucella is a facultative intracellular bacterium and cell mediated immunity plays essential roles for protection against Brucella infection. Identification of Brucella antigens that present T-cell epitopes to the host could enable develo...
Phosphorylation of myosin regulatory light chain (RLC) triggers contraction in smooth muscle myocytes. Dephosphorylation of phosphorylated RLC (pRLC) is mediated by myosin RLC phosphatase (MLCP), which is negatively regulated by rho-associated kinase (ROK). We have compared basal and stimulated concentrations of pRLC in myocytes from human coronary artery (hVM), which has a tonic contractile pa...
Sequencing of bp26, the gene encoding the Brucella sp. immunogenic BP26 periplasmic protein, was performed in the reference strains of Brucella abortus, B. suis, and B. ovis. The three bp26 sequences were almost identical to that published for B. melitensis 16M bp26, and only minor nucleotide substitutions, without modifying the amino acid sequence, were observed between species. The bp26 genes...
Remains of a monumental structure linked with the Funnel Beaker culture were discovered in Strzeszkowice Duże (Lublin District, Poland) during rescue excavation carried out prior to investment works (building expressway S19 from Lublin Kraśnik). The did not contain any burial chamber or burial. In one ditches forming outline construction, there was hoard nine artefacts made Świeciechów flint.
OBJECTIVE The present study was designed to evaluate whether CP was beneficial in alleviating myocardial fibrosis following I/R injury. METHODS Sprague-Dawley rats were subjected to 30 minutes occlusion of the LADCA, followed by reperfusion. CP (0.4 or 0.8 g/kg) was daily administered starting from three hour after reperfusion until day 6. Coronary venular diameter, RBC velocity, albumin leak...
BACKGROUND Human brucellosis is a preventable zoonoses that may become persistent, causing, if left untreated, severe localized disease. Occupational exposure to infected animals or animal products and consumption of fresh contaminated dairy are main risk factors. METHODS One hundred farmworkers employed at two cattle farms one in Khartoum North and one in Omdurman were screened for the prese...
The involvement of Rho-associated kinase (ROK) in activation of rabbit urethral smooth muscle contraction was investigated by examining the effects of two structurally distinct inhibitors of ROK, Y27632 and H1152, on the contractile response to electric field stimulation, membrane depolarization with KCl, and α1-adrenoceptor stimulation with phenylephrine. Both compounds inhibited contractions ...
A method of cultivating Brucella abortus S19 culture in bioreactor was attempted using three different media. Culture conditions in bioreactor were optimized by varying agitation and aeration parameters. Varying the aeration ranging from 0.5 vvm to 0.8 vvm and agitation rate ranging from 250 rpm to 400 rpm during bacterial growth was found to yield highest viable count within 48 hours of cultur...
