Determination of Acephate, Dinotefuran, and Emamectin Benzoate in a Pesticide Formulation: A Single-Laboratory Validation.

Background: The advantage of simultaneous separation and quantification is the reduction of analysis time and consumption of solvents and reagents.

Objective: The objective of the present investigation was to optimize and validate a novel, rapid, and simple reverse-phase high-performance liquid chromatographic method for the simultaneous determination of acephate, dinotefuran, and emamectin benzoate in a pesticide formulation.

Method: The chromatographic separation and quantification were accomplished by using Kromasil CN column (250 mm × 4.

A novel validated simple derivatization liquid chromatographic method with diode array detection for the simultaneous determination of mancozeb, azoxystrobin and difenoconazole in pesticide dosage form.

A novel, rapid and simple reverse-phase high performance liquid chromatography (RP-HPLC) method for the simultaneous determination of three pesticides - mancozeb, azoxystrobin and difenoconazole by derivatization with ethyl iodide is presented. Analysis was performed on a C18 column (Agilent Eclipse plus, 150 mm × 4.6 mm; 5 μ) with the mobile phase consisting of acetonitrile + methanol (90 + 10 v/v) - water (0.

An innovative 'Prop technique' of mouth opening in post-COVID-19 mucormycosis maxillectomy: Finding a new way with minimal efforts.

General anaesthesia is associated with damage to teeth, particularly during laryngoscopy. Dental injury is more probable when pre-existing dental pathology or risk factors are present. Post-coronavirus disease -2019 mucormycosis is a rare, fulminant, lethal, angio-invasive, opportunistic fungal disease and is increasingly recognised in diabetic and immunocompromised patients.

Prospective Observational Study of Comparison Between Direct and High-Pressure Primary Trocar Entry in Gynaecological Laparoscopy in Teaching Hospital.

Background: Laparoscopic port entry is crucial and vital step in any laparoscopic surgery. As laparoscopy is widely used, complications related to it are also increasing which are not seen in conventional laparotomy.

Aim: The present study was undertaken to compare the ease of primary trocar entry after pneumoperitoneum at 20 mmHg pressure and direct trocar entry without pneumoperitoneum.

A four-component modified Biginelli reaction: A novel approach for C-2 functionalized dihydropyrimidines.

A novel four component modified Biginelli reaction for the synthesis of C-2 functionalized dihydropyrimidines has been established. The approach uses assembly of less explored acetyl acetone with aromatic aldehyde, thiourea, and dimethyl sulphate to construct a novel 5-acetyl 2-methylthio dihydropyrimidine system, which works as an efficient well-designed intermediate for generating C-2 modified Biginelli libraries with nitrogen nucleophiles. Phenyl hydrazine, semicarbazide, and aryl semicarbazides are successfully used as N-nucleophiles to generate C-2 functionalized dihydropyrimidine derivatives, which fulfil the demands of active pharmacophore.
