Nanobiosensors based on on-site detection approaches for rapid pesticide sensing in the agricultural arena: A systematic review of the current status and perspectives.

The extensive use of chemical pesticides has significantly boosted agricultural food crop yields. Nevertheless, their excessive and unregulated application has resulted in food contamination and pollution in environmental, aquatic, and agricultural ecosystems. Consequently, the on-site monitoring of pesticide residues in agricultural practices is paramount to safeguard global food and conservational safety.

Molecular properties prediction, synthesis, and antimicrobial activity of bis(azolyl)sulfonamidoacetamides.

A library of bis(azolyl)sulfonamidoacetamides was prepared by the reaction of azolylsulfonylamines with azolylchloroacetamides in the presence of pyridine/4-(dimethylamino)pyridine (DMAP) under ultrasonication. The reaction proceeded well with DMAP, resulting in a higher yield of the products. The antimicrobial activity of the compounds indicated that N-{5-[N-(2-{[4-(4-chloro-1H-pyrrol-2-yl)-1H-imidazol-2-yl)amino}-2-oxoethyl)sulfamoyl]-4-phenylthiazol-2-yl}benzamide (22a), N-{5-[N-(2-{[4-(4-chloro-1H-pyrrol-2-yl)-1H-imidazol-2-yl]amino}-2-oxoethyl)sulfamoyl]-4-(4-chlorophenyl)thiazol-2-yl}benzamide (22c), and N-{5-[N-(2-{[4-(4-chloro-1H-pyrrol-2-yl)-1H-imidazol-2-yl]amino}-2-oxoethyl)sulfamoyl]-4-(4-chloro-phenyl)-1H-imidazol-2-yl}benzamide (24c) exhibited a low minimal inhibitory concentration (MIC) against Bacillus subtilis, equal to the standard drug, chloramphenicol.

Elucidation and genetic intervention of CO concentration mechanism in for increased plant primary productivity.

The rising global population is forcing the need for adapting alternative sustainable technologies for enhanced crop productivity. The CO Concentration Mechanisms (CCMs) evolved in algae to counter the inefficient CO fixing enzyme, RuBisCo and slower diffusion of CO in water offers good scope for the above purpose. The CCMs are single-celled CO supply mechanisms that depend on multiple CO/HCO transporters and acclimation states and accumulate 100-fold more CO than low CO environments.

Impact of nutritional status/risk and post-operative nutritional management on clinical outcomes in patients undergoing gastrointestinal surgery: a prospective observational study.

Background: Malnutrition is prevalent in patients undergoing gastrointestinal (GI) surgery and has been linked to adverse outcomes. The present study aimed to determine the association between early post-operative nutritional status/risk, post-operative nutritional management and clinical outcomes.

Methods: A prospective observational study was conducted in GI surgical patients with a minimum 3-day post-operative length of stay (LOS).
