Present study was carried out regarding enzymatic assay for 5'-nucleotidase enzymes present in snake venom Naja naja karachiensis and to evaluate twenty eight medicinal plants as their antidotes. Elevated enzymatic activities i.e., 119, 183, 262 and 335 U/mL were observed in 10, 20, 30 and 40 µg of crude venom, respectively, in dose dependent manner. Among various plant extracts only two (Bauhi...

The major objective of this work has been to learn the effect of plague toxin on several enzymatic systems in vitro. The availability of purified preparations of plague toxin (Ajl et al., 1955) permitted us to carry out these investigations. In this report, experiments are described in which purified plague toxin has been added to actively respiring cell-free extracts and crude mouse liver homo...

The pioneering studies of Hofmann and co-workers on the lipids of lactobacilli led to the discovery of a 19 carbon fatty acid containing a cyclopropane ring (l-5). This acid was characterized as cis-11 ,12-methyleneoctadecanoic acid and was given the trivial name, lactobacillic acid. A 17 carbon fatty acid from Escherichia coli was described by Dauchy and Asselineau (6) and characterized as cis...

BACKGROUND Staphylococcus aureus is the direct reason of mastitis. Mastitis is a disease characterized by pathological changes in mammary glands as well as physical, chemical, bacteriological changes in milk. This disease causes loses in milk yield and quality. In recent years, it is reported that mastitis pathogens have developed a resistance to antibiotics as a natural consequence of widespre...

Enzymatic extraction was investigated to improve the quality of black tea extracts with pretreatment of pectinase and tannase independently, successively and simultaneously. Pectinase improved the extractable-solids-yield (ESY) up to 11.5%, without much of an improvement in polyphenols recovery, while tannase pre-treatment showed a significant improvement in polyphenols recovery (14.3%) along w...

Herein, a non-enzymatic and label-free strategy based on DNA-fueled molecular machine was developed for ultrasensitive detection of telomerase activity in cancer cell extracts even at the single-cell level.

Trigonella foenum-gracum L. (Fenugreek) (Leguminosae) is employed as an herbal medicine. Its seeds are known for their carminative, tonic and antidiabetic effects. In the present study, we investigated the hypoglycaemic activities of the hydroalcoholic, ethanolic and chloroformic extracts of the Trigonella foenum-gracum seeds in streptozotocin-diabetic rats using interperitoneall (i.p.) adminis...

Enzymatic analyses of Bacillus thuringiensis extracts suggest that a modified Krebs tricarboxylic acid cycle (without alpha-ketoglutarate dehydrogenase) can operate during sporulation in conjunction with the glyoxylic acid cycle and the gamma-aminobutyric acid pathway.
