Strained Ion Pair Interactions-Driven Anion-Assisted Concerted Addition of Ketoximes/Aldoximes and Hydroxamic Acids to Glycals.

Oximes and hydroxylamides are notable for their role as coupling partners in organic synthesis. However, their direct application as acceptors in -glycosylation with glycal donors remains largely unexplored. Herein, we introduce a novel 2-deoxy glycosylation method for synthesizing N-O linked glycosides facilitated by sterically strained 2,4,6-tri--butylpyridinium salts.

Noncommunicable Diseases and Gender Gap in Out-of-pocket Spending on Inpatient Health Care: An Investigation of Indian Elderly.

The present study intends to examine whether there exists any gender gap in out-of-pocket spending on hospitalization between elderly men and elderly women. Data were drawn from the NSS 75th Round Health Care Survey (2017-2018) consisting of a total number of 45,299 elderly. Bivariate analysis and t-test were used to examine the disease burden and gender gap in health spending.

Triple Role of Proton Sponge (DMAN) in the Palladium-Catalyzed Direct Stereoselective Synthesis of -Aryl Glycosides from Glycals.

The triple role of 1,8-bis(dimethylamino)naphthalene (proton sponge) as a reductant, ligand precursor, and organic base in the palladium-catalyzed Heck-type coupling reaction of glycals with aryl iodides affords the rapid and stereoselective synthesis of 2',3'-unsaturated α--aryl glycosides in excellent yields. The role of the proton sponge in reducing palladium(II) to (0) has been studied using cyclic voltammetry, UV-vis, HRMS, and other spectroscopic techniques. This is the first example of a palladium proton sponge complex utilized in coupling reactions.

Enhanced efficiency of water desalination in nanostructured thin-film membranes with polymer grafted nanoparticles.

Polyamide composite (PA-TFC) membranes are the state-of-the-art ubiquitous platforms to desalinate water at scale. We have developed a novel, transformative platform where the performance of such membranes is significantly and controllably improved by depositing thin films of polymethylacrylate [PMA] grafted silica nanoparticles (PGNPs) through the venerable Langmuir-Blodgett method. Our key practically important finding is that these constructs can have unprecedented selectivity values (, ∼250-3000 bar, >99.

Food neophobia and its association with sociodemographic factors and food preferences among Bangladeshi university students: Evidence from a cross-sectional study.

Food neophobia, described as a reluctance to eat and or avoid new food, is a personality trait that affects food choice. Despite its potential influence on an individual's food intake, food neophobia has been poorly investigated in Bangladesh. This cross-sectional study was designed to evaluate food neophobia and its association with sociodemographic factors and food preferences in a sample of Bangladeshi university students.

Effect of Soil Amendments on Microbial Resilience Capacity of Acid Soil Under Copper Stress.

An incubation study was undertaken to study microbial resilience capacity of acid soil amended with farmyard manure (FYM), charcoal and lime under copper (Cu) perturbation. Copper stress significantly reduced enzymatic activities and microbial biomass carbon (MBC) in soil. Percent reduction in microbial activity of soil due to Cu stress was 74.

Trends to access internet among medical students of a government medical college in West Bengal.

The use of computer and information technology is on an escalation. The internet, one of the key developments in this field, provides instant access to latest medical information. The present study was conducted (i) to estimate the extent and purpose of internet usage among undergraduate (UG) and postgraduate (PG) medical students, (ii) to identify factors that encourage the students to use internet for medical information, (iii) to assess the need for incorporating computer education in medical curriculum.
