The changing association between pandemic-related stressors and child and adolescent mental health during the waning phase of the COVID-19 pandemic.

This study examined the relation between pandemic-related stressors and mental health among young people (YP) in India during two time points in the waning phase of the pandemic. We use data from two cross-sectional waves of over 20,000 YP aged 5-19 in February 2022, during the peak of the Omicron wave, and October 2022, during a reduction in infections and easing of restrictions. COVID illness/death in the family's social network, current lockdown stringency, and significant change in household income were examined in relation to adult respondents' reports of YP internalizing symptoms.

Boosting Vaccine Response in Autoimmune Rheumatic Disease Patients With Inadequate Seroconversion: An Analysis of the Immunogenicity of Vector-Based and Inactivated Vaccines.

Background: An additional dose of COVID-19 vaccine is being offered to vaccinated people, especially those immunocompromised. The most widely available vaccines in India are the adenoviral vector-based AZD1222 (ChAdOx1 nCoV-19) and the heat-inactivated (BBV152). This study investigated the efficacy of both vaccines in patients with autoimmune rheumatic diseases (AIRD).

Controlling π-Conjugated Polymer-Acceptor Interactions by Designing Polymers with a Mixture of π-Face Strapped and Nonstrapped Monomers.

Controlling π-conjugated polymer-acceptor complex interaction, including the interaction strength and location along the polymer backbone, is central to organic electronics and energy applications. Straps in the strapped π-conjugated polymers mask the π-face of the polymer backbone and hence are useful to control the interactions of the π-face of the polymer backbone with other polymer chains and small molecules compared to the conventional pendant solubilizing chains. Herein, we have synthesized a series of strapped π-conjugated copolymers containing a mixture of strapped and nonstrapped comonomers to control the polymer-acceptor interactions.

Comparing population-level humoral and cellular immunity to SARS-Cov-2 in Bangalore, India.

Two types of immunity, humoral and cellular, offer protection against COVID. Humoral protection, contributed by circulating neutralizing antibodies, can provide immediate protection but decays more quickly than cellular immunity and can lose effectiveness in the face of mutation and drift in the SARS-CoV-2 spike protein. Therefore, population-level seroprevalence surveys used to estimate population-level immunity may underestimate the degree to which a population is protected against COVID.

What drives poor quality of care for child diarrhea? Experimental evidence from India.

Most health care providers in developing countries know that oral rehydration salts (ORS) are a lifesaving and inexpensive treatment for child diarrhea, yet few prescribe it. This know-do gap has puzzled experts for decades. Using randomized experiments in India, we estimated the extent to which ORS underprescription is driven by perceptions that patients do not want ORS, provider's financial incentives, and ORS stock-outs (out-of-stock events).

Transgenic sugarcane overexpressing improved germination and biomass production at formative stage under salinity and water-deficit stress conditions.

The glyoxalase system, involving Glyoxalase I (GlyI) and Glyoxalase II (Gly II), plays a vital role in abiotic stress tolerance in plants. A novel enzyme Glyoxalase III (Gly III) was found recently from bacteria, yeast, and plant species. This enzyme provides a new way to detoxify Methylglyoxal (MG), a cytotoxic α-oxoaldehyde, which, in excess, can cause complete cell destruction by forming Reactive Oxygen Species (ROS) and Advanced Glycation End products (AGEs) or DNA/RNA mutation.

Graph Attention Network based mapping of knowledge relations between chemical spaces of Nuclear factor kappa B and Centella asiatica.

The confounding nature of the innate immunity target Nuclear Factor kappa B (NF-κB) and its interaction with Centella asiatica (CA) molecules necessitate the intervention of advanced technologies, such as deep learning methods. The integration of chemical space concepts with deep learning technologies is a new way of knowledge mapping used to explore drug-target interactions, especially in molecular libraries derived from traditional medicine based molecular sources. The current constraint of virtual screening for mechanistic target hunting is the use of a binary classification model that includes active and inactive molecules from in vitro experiments to explore drug-target interaction.

Efficacy and safety of curcumin in maintaining remission during disease-modifying antirheumatic drug withdrawal in rheumatoid arthritis at 52 weeks: a phase III double-blind, randomized placebo-controlled trial.

Curcumin has anti-inflammatory properties but current evidence is limited to advocate its use in rheumatoid arthritis (RA). We explored whether curcumin could maintain remission in patients with RA while tapering conventional synthetic Disease-Modifying Antirheumatic Drugs (csDMARD). In this patient-and investigator-blinded trial, adults with RA in sustained remission for more than six months were randomized to oral curcumin (1 g) with piperine (5 mg) twice daily or matching placebo.

Isolation of 5' regulatory region of gene and its functional characterization through transient expression analysis in tobacco and sugarcane.

Unlabelled: Chilling Tolerant Divergence 1 () gene consists of Golgi pH Receptor (GPHR) as well as Abscisic Acid-linked G Protein-Coupled Receptor (ABA_GPCR), which are the major transmembrane proteins in plants. This gene expression has been found to be differentially regulated, under various stress conditions, in wild -related genera, , compared to commercial sugarcane variety. In this study, Rapid Amplification of Genomic Ends (RAGE) technique was employed to isolate the 5' upstream region of COLD1 gene to gain knowledge about the underlying stress regulatory mechanism.

Role of mesenchymal stem cells and short chain fatty acids in allergy: A prophylactic therapy for future.

Allergic diseases are broadly classified as IgE-mediated type-I hypersensitivity immune reactions due to exposure to typically harmless substances known as allergens. These allergenic substances activate antigen presenting cells, which further triggers T-helper 2 cells immune response and class switch B-cells for synthesis of allergen-specific IgE, followed by classical activation of inflammatory mast cells and eosinophils, which releases preformed mediators involved in the cascade of allergic symptoms. However, the role of Mesenchymal stem cells (MSCs) in tissue repair ability and immunomodulation, makes them as an appropriate tool for treatment of various allergic diseases.

Using molecular straps to engineer conjugated porous polymer growth, chemical doping, and conductivity.

Controlling network growth and architecture of 3D-conjugated porous polymers (CPPs) is challenging and therefore has limited the ability to systematically tune the network architecture and study its impact on doping efficiency and conductivity. We have proposed that π-face masking straps mask the π-face of the polymer backbone and therefore help to control π-π interchain interactions in higher dimensional π-conjugated materials unlike the conventional linear alkyl pendant solubilizing chains that are incapable of masking the π-face. Herein, we used cycloaraliphane-based π-face masking strapped monomers and show that the strapped repeat units, unlike the conventional monomers, help to overcome the strong interchain π-π interactions, extend network residence time, tune network growth, and increase chemical doping and conductivity in 3D-conjugated porous polymers.

Correlates of breakthrough Omicron (B.1.1.529) infections in a prospective cohort of vaccinated patients with rheumatic diseases.

Background: Data on the effectiveness of SARS-CoV-2 vaccines and the durability of protection against the prevalent Omicron variant are scarce, especially in patients with autoimmune rheumatic diseases (AIRDs). Hence, we prospectively studied Omicron breakthrough infections in patients with AIRDs and attempted to isolate associated risk factors.

Methods: Patients with AIRDs who had completed primary vaccination with either AZD1222 or BBV152 vaccines were included and prospectively followed up from January 2022 onwards for the development of breakthrough Omicron infections.

Does the market reward quality? Evidence from India.

There are two salient facts about health care in low and middle-income countries; (1) the private sector plays an important role and (2) the care provided is often of poor quality. Despite these facts we know little about what drives quality of care in the private sector and why patients seek care from poor quality providers. We use two field studies in India that provide insight into this issue.

Visualizing COVID Restrictions: Activity Patterns Before, During, and After COVID-19 Lockdowns in Uttar Pradesh, India.

Globally, restrictions implemented to limit the spread of COVID-19 have highlighted deeply rooted social divisions, raising concerns about differential impacts on members of different groups. Inequalities among households of different castes are ubiquitous in certain regions of India. Drawing on a novel data set of 8,564 households in Uttar Pradesh, the authors use radar plots to examine differences between castes in rates of activity for several typical behaviors before, during, and upon lifting strict lockdown restrictions.

The role of gut microbiota in clinical complications, disease severity, and treatment response in severe alcoholic hepatitis.

Background: Dysbiotic gut bacteria engage in the development and progression of severe alcoholic hepatitis (SAH). We aimed to characterize bacterial communities associated with clinical events (CE), identify significant bacteria linked to CE, and define bacterial relationships associated with specific CE and outcomes at baseline and after treatment in SAH.

Methods: We performed 16-s rRNA sequencing on stool samples (n=38) collected at admission and the last follow-up within 90 days in SAH patients (n=26; 12 corticosteroids; 14 granulocyte colony-stimulating factor, [G-CSF]).

Molecular tetrominoes: selective masking of the donor π-face to control the configuration of donor-acceptor complexes.

Understanding the doping mechanism in organic semiconductors and generating molecular design rules to control the doping process are crucial for improving the performance of organic electronics. Even though controlling the location and orientation of the dopant along the semiconductor backbone is an important step in the doping mechanism, studies in this direction are scarce as it is a challenging task. To address this, herein, we incorporated π-face masked (strapped) units in 1,4-bis(phenylethynylene)benzene (donor) to control the acceptor (dopant) location along the trimer, donor-acceptor binding strength, and acceptor ionization.

Transjugular intrahepatic portosystemic shunt (TIPS) placement at index portal hypertensive decompensation (anticipant TIPS) in cirrhosis and the role of early intervention in variceal bleeding and ascites.

Background: Transjugular intrahepatic portosystemic shunt (TIPS) placement improves survival in patients with refractory/recurrent acute variceal bleeding (RAVB) and refractory ascites/hydrothorax. Recently, early TIPS was shown to reduce rebleeding and improve survival compared to the conventional TIPS. We aimed to study outcomes in patients with cirrhosis undergoing TIPS at first significant portal hypertensive (PHT) decompensation (termed anticipant TIPS) compared to those undergoing TIPS for recurrent or persistent PHT complications (conventional) and compared the former to matched controls on standard medical management (SMT).

Overexpression of Glyoxalase III gene in transgenic sugarcane confers enhanced performance under salinity stress.

The glyoxalase pathway is a check point to monitor the elevation of methylglyoxal (MG) level in plants and is mediated by glyoxalase I (Gly I) and glyoxalase II (Gly II) enzymes in the presence of glutathione. Recent studies established the presence of unique DJ-1/PfpI domain containing protein named glyoxalase III (Gly III) in prokaryotes, involved in the detoxification of MG into D-lactic acid through a single step process. In the present study, eleven transgenic sugarcane events overexpressing EaGly III were assessed for salinity stress (100 mM and 200 mM NaCl) tolerance.
