Electrodiffusioosmosis induced negative differential resistance in micro-to-millimeter size pores through a graphene/copper membrane.

Negative differential resistance (NDR) is one of the nonlinear transport phenomena in which ionic current decreases with the increase in electromotive potential. Electro-osmosis, diffusio-osmosis, and surface charge density of pores are the driving forces for observing NDR in nanoscale ion transport. Here, we report electrodiffusioosmosis induced NDR using micro to millimeter size pores in a two-dimensional (2D) graphene-coated copper (Gr/Cu) membrane.

Design and development of an automated experimental setup for ion transport measurements.

The ion transport measurements using various ion-exchange membranes (IEMs) face several challenges, including controllability, reproducibility, reliability, and accuracy. This is due to the manual filling of the solutions in two different reservoirs in a typical diffusion cell experiment with a random flow rate, which results in the diffusion through the IEM even before turning on the data acquisition system as reported so far. Here, we report the design and development of an automated experimental setup for ion transport measurements using IEMs.

Study of antibiotics sensitivity pattern and molecular characterization of Staphylococcus aureus isolated from human and animal pyogenic cases.

Staphylococcus aureus has been described as the most common cause of human and animal diseases and has emerged as a superbug due to multidrug resistance. Considering these, a total of 175 samples were collected from pyogenic cases of humans (75) and animals (100), to establish the drug resistance pattern and also for molecular characterization of human and animal isolates. Thermonuclease (nuc) gene amplification was used to confirm all presumptive S.

Twist-Dependent Tuning of Excitonic Emissions in Bilayer WSe.

Monolayer (ML) transition metal dichalcogenides (TMDCs) have been rigorously studied to comprehend their rich spin and valley physics, exceptional optical properties, and ability to open new avenues in fundamental research and technology. However, intricate analysis of twisted homobilayer (t-BL) systems is highly required due to the intriguing twist angle (t-angle)-dependent interlayer effects on optical and electrical properties. Here, we report the evolution of the interlayer effect on artificially stacked BL WSe, grown using chemical vapor deposition (CVD), with t-angle in the range of 0 ≤ θ ≤ 60°.

Prevalence and antibiotyping of Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) in domestic animals in India.

Objectives: Domestic animals can serve as a reservoir for antimicrobial-resistant Staphylococcus aureus and may lead to the emergence of drug-resistant human isolates. The present study aimed to assess the prevalence and antibiotypes of S. aureus and methicillin-resistant S.

Classical swine fever in India: current status and future perspective.

Classical swine fever (CSF) is a globally significant disease of swine caused by classical swine fever virus. The virus affects the wild boars and pigs of all age groups, leading to acute, chronic, late-onset or in-apparent course of the disease. The disease causes great economic loss to the piggery industry due to mortality, stunted growth, poor reproductive performance, and by impeding the international trade of pig and pig products.

A Study of Cardiovascular Abnormalities in HIV Positive Patients in a Tertiary Care Hospital in Northern India.

Introduction: Cardiovascular illness is common in patients with HIV infection, particularly in the later course of disease. Cardiovascular abnormalities in people living with HIV disease (PLHIV) often go unrecognized or untreated resulting in increased cardiovascular related morbidity and mortality and reduced quality of life. The prevalence of cardiac involvement in PLHIV has been reported to range between 28 to 73%.

Rotational Dynamics in Ionic Liquids from NMR Relaxation Experiments and Simulations: Benzene and 1-Ethyl-3-Methylimidazolium.

Temperature-dependent (2)H longitudinal spin relaxation times (T1) of dilute benzene-d6 in 1-butyl-3-methylimidazolium tetrafluoroborate ([Im41][BF4]) and two deuterated variants of the 1-ethyl-3-methylimidazolium cation (Im21(+)-d1 and Im21(+)-d6) in 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([Im21][Tf2N]), measured at multiple Larmor frequencies, were used to probe rotational dynamics in ionic liquids. Rotational correlation times significantly faster than predicted by slip hydrodynamic calculations were observed for both solutes. Molecular dynamics simulations of these systems enabled extraction of more information about the rotational dynamics from the NMR data than rotation times alone.

Ebstein's anomaly with recurrent massive pericardial effusion: a rare presentation.

Ebstein's anomaly is known for its varied presentations and exceptionally long survival in some cases. Here the authors describe a case of previously undiagnosed Ebstein's anomaly in a patient who presented with massive pericardial effusion. Over the next 6 months, the patient was hospitalised twice for pericardiocentesis.

How Is Diffusion of Neutral and Charged Tracers Related to the Structure and Dynamics of a Room-Temperature Ionic Liquid? Large Deviations from Stokes-Einstein Behavior Explained.

The deviations from Stokes-Einstein hydrodynamics of small solutes are more pronounced in ionic liquids than in conventional solvents (J. Phys. Chem.

Evaluation of goat based 'indigenous vaccine' against bovine Johne's disease in endemically infected native cattle herds.

'Indigenous vaccine' prepared from 'Indian Bison Type' a native bio-type of Mycobacterium avium subspecies paratuberculosis strain 'S5' of goat origin (goat based) was evaluated in indigenous cattle herds located in gaushalas (cow shelters), endemic for Bovine Johne's disease. Cows (893) were randomly divided into vaccinated (702 = 626 adults + 76 calves) and control (191 = 173 adults + 18 calves) groups. Response to vaccination was evaluated on the basis of health (mortality, morbidity), productivity (growth rate, reproductive performance, total milk yield), immunological parameters (LTT, ELISA titer), survivability of animals naturally infected with MAP, bacterimia (by specific blood PCR), seroconversion (by indigenous ELISA) and status of shedding of MAP in feces (by microscopy) in the two groups before and after vaccination.

Studies on Antimicrobial and Immunomodulatory Effects of Hot Aqueous Extract of Acacia nilotica L. Leaves against Common Veterinary Pathogens.

Acacia nilotica is a plant species that is almost ubiquitously found in different parts of the world. Various preparations of it have been advocated in folk medicine for the treatment of tuberculosis, leprosy, smallpox, dysentery, cough, ophthalmia, toothache, skin cancer as astringent, antispasmodic, and aphrodisiac since immemorial times. The present study investigates the antibacterial, antifungal, antiviral, and immunomodulatory potential of hot aqueous extract (HAE) of Acacia nilotica leaves.
