Tuberculosis (TB) ranks second, next to AIDS making it most formidable disease if the present age. One of the crucial enzymes involved in cell wall synthesis of Mycobacterium tuberculosis, InhA (enoyl acyl carrier protein reductase) has been authenticated as an effective target for anti-mycobacterial drug development. In the current work, we have developed novel derivatives of 1,2,4-triazole-5-...

Methotrexate was determined by the homogeneous enzyme immunoassay (EMIT) with the Multistat and CentrifiChem centrifugal analyzers and by the enzyme inhibition assay with use of the Multistat centrifugal analyzer. With both methods, the standard curve extends from 0.2 to 2.0 mumol/L and there is no interference from bilirubin in concentrations up to 100 mg/L. Moderately lipemic samples do not i...

conclusions: it was concluded that the elisa is a suitable method for large scale screening of antibodies against aspergilloma. the easy techniques have shortened the required time of tests (approximately 1.30 hours for our elisa, as opposed to 2.30 hours with commercial elisa kit). this may be a substantial benefit for large numbers of samples that should be tested. materials and methods: an i...

background: nuts are one of the main consumed snacks worldwide and also have an important role among iranian's food habits. natural contamination of nuts with aflatoxin is unavoidable and causes a special challenge for nuts safety and quality. objectives: the purpose of this research was to study the aflatoxin contamination in commercially-available nuts (pistachio, walnut and peanut) in the ma...

b ackground : tuberculosis is a crucial health problem. establishing a rapid, reliable and still inexpensive diagnostic method for tuberculosis seems to be substantial in developing countries where tb has very high incidence rate . methods:   an indirect  enzyme-linked  immunosorbent  assay (elisa )   was established to detect serum antibodies against mycobacterium  tuberculosis. three kinds of...

conclusions afm1 contamination of milk is not a concern in this city. however, dairy cattle feed samples of various livestocks must be regularly checked for aflatoxin and the storage conditions of feeds should be strictly controlled. results afm1 was detected in all milk samples. the mean concentration of afm1 was 11.61 ± 0.72 ng/l with a range of 6.3-23.3 ng/l. none of the samples had levels e...
