Study of the Effect of Methyl Jasmonate Concentration on Aflatoxin B1 Biosynthesis by Aspergillus parasiticus in Yeast Extract Sucrose Medium

Aflatoxin B(1) (AFB(1)) is a carcinogenic metabolite produced by certain Aspergillus species on agricultural commodities. AFB(1) biosynthesis is affected by jasmonic acid and also by its methylester (MeJA), a plant growth regulator derived from linoleic acid. This study reports the effect of MeJA on the growth of A. parasiticus and AFB(1) output in yeast extract sucrose (YES) medium when added ...

Rifampin resistance and diabetes mellitus in a cross-sectional study of adult patients in rural South India

BACKGROUND Despite increasing reports of the linkage between diabetes and tuberculosis (TB), there is limited information regarding diabetes and TB drug resistance. METHODS In this cross-sectional study, sputum and blood samples were collected from 304 adult patients in rural Andhra Pradesh. Rifampin resistance was assessed by Xpert MTB/RIF (Xpert), and diabetes status was based on self-repor...

The Impact of Correction for Guessing Formula on MC and Yes/No Vocabulary Tests' Scores

A standard correction for random guessing (cfg) formula on multiple-choice and Yes/Noexaminations was examined retrospectively in the scores of the intermediate female EFL learners in an English language school. The correctionwas a weighting formula for points awarded for correct answers,incorrect answers, and unanswered questions so that the expectedvalue of the increase in test score due to g...

Mutations in the rpoB gene of rifampin-resistant Mycobacterium tuberculosis isolates in Spain and their rapid detection by PCR-enzyme-linked immunosorbent assay.

Genetic alterations in the rpoB gene were characterized in 50 rifampin-resistant (Rif(r)) clinical isolates of Mycobacterium tuberculosis complex from Spain. A rapid PCR-enzyme-linked immunosorbent assay (ELISA) technique for the identification of rpoB mutations was evaluated with isolates of the M. tuberculosis complex and clinical specimens from tuberculosis patients that were positive for ac...
