Hydropersulfide (RSSH)-Mediated Hydrothiolation of Alkenes.

A hydropersulfide-mediated hydrothiolation reaction of alkenes has been developed for C-S bond formation with Markovnikov selectivity. This new approach is a transition-metal-, additive-, and solvent-free reaction under mild conditions. The reaction is postulated to proceed by an ionic mechanism with the release of elemental sulfur based on our control experiments and density functional theory calculations.

Reference interval of Hemoglobin: Findings from a Cross Sectional Study in Adult Population of Dhaka, Bangladesh.

Hemoglobin is a common hematological parameter assessed in laboratory and also an important tool for clinical management of patients. Reference values being used in most laboratories in our country, have been provided from the established reference values of developed countries. Hemoglobin concentration varies usually due to age, sex, attitude, ethnic origin, dietary habits, socioeconomic status and environmental factor.

represses type VI secretion system through a manganese-dependent small RNA-mediated regulation.

Type VI secretion system (T6SS) is utilized by many Gram-negative bacteria to eliminate competing bacterial species and manipulate host cells. ATCC 17978 utilizes T6SS at the expense of losing pAB3 plasmid to induce contact-dependent killing of competitor microbes, resulting in the loss of antibiotic resistance carried by pAB3. However, the regulatory network associated with T6SS in remains poorly understood.

Principles and biomechanical response of normal gait cycle to measure gait parameters for the alignment of prosthetics limb: A technical report.

The limb amputations caused due to emergent incidents of trauma injuries and vascular diseases currently represent crucial global problems. The patients/amputees with limb amputation who lost the residual limb (knee-ankle foot system) must depend on the prosthetic limb. Prosthetic clinicians and technicians have attempted to develop optimal limb prosthetics that will enhance the ability and functional elements of the patients/users.

Critical Role of Water beyond the Media to Maintain Protein Stability and Activity in Hydrated Deep Eutectic Solvent.

Hydrated deep eutectic solvents (DESs) are recognized for their potential in biocatalysis due to their tunability, biocompatibility, greenness, and ability to keep protein stable and active. However, the mechanisms governing enzyme stability and activity in DES remain poorly understood. Herein, using bromelain as the model enzyme and acetamide (0.
