Environmentally friendly multipurpose grease formulation has been synthesized by using Jatropha vegetable residual oil with lithium soap and multifunctional additive. The thus obtained formulation was evaluated for its tribological performance on a four-ball tribo-tester. The anti-friction and anti-wear performance characteristics were evaluated using standard test methods. The biodegradability...

stachys lavandulifolia is used as the herbal tea and its wide and potent medical effects have been reported for the extract in animal studies. this study aimed to find the safety profile of the extract to find the appropriate doses for further human studies. the aerial parts of the plant were air-dried and the hydroalcoholic extract was obtained and concentrated by percolation method with 140 m...

Abstract Evaluation studies were carried out to simulate realistic field exposures of sulfoxaflor and flonicamid against Aphis gossypii at foraging time Apis mellifera . Semi-field trials rates A. laboratory strain 48 h exposure had equipollent overall mean mortality 62.50 63.50%, respectively in season 2020, likewise 60.50 62.50%, 2021. Lethal values (LT 1 ) ranges 51.33–32.46 days for 49.00–3...

Dihydropyrimidinase (DHP) is the second enzyme in the catabolism of 5-fluorouracil (5FU), and it has been suggested that patients with a deficiency of this enzyme are at risk from developing severe 5FU-associated toxicity. In this study, we demonstrated for the first time that in one patient the severe toxicity, after a treatment with 5FU, was attributable to a partial deficiency of DHP. Analys...

Purified cholera enterotoxin was prepared by methods described by Finkelstein and Lo Spalluto (1970). This toxin was detoxified by treatment with heat and formaldehyde. Heating cholera toxin at 60 C for 25 min resulted in the formation of a polymer named procholeragenoid by Finkelstein et al. (1971). The weak toxic activity of this product was removed by treatment with formalin. No residual tox...
