Corticosteroids induced avascular necrosis of hip, a "long COVID-19" complication: Case report.

Introduction And Importance: Since it first surfaced, the new Coronavirus has multiplied and mutated into different forms, leading to a significant impact on people's lives. COVID-19's long-term impact is not completely known; It can only be hypothesized based on the prior outbreak of severe acute respiratory syndrome (SARS). Avascular necrosis (AVN) is one of these consequences, which if left untreated can lead to catastrophic events and bone collapse.

Freshwater discharge from the large and coastal peninsular rivers of India: A reassessment for sustainable water management.

This study offers an updated mean annual water discharge of 10 large and 11 coastal basins of the Indian Peninsula and looks into environmental parameters influencing the water flux and discharge trends. The mean annual discharge of large and coastal rivers is estimated to be 221 and 294 km. Thus, despite draining 25% of the Indian Peninsula, coastal rivers deliver more than half of the annual flux, and west-flowing coastal rivers contribute 85% of it.

Quality improvement initiative to decrease extrauterine growth restriction in preterm neonates.

Background: Prevention of extrauterine growth restriction (EUGR) in preterm neonates is one of the biggest challenges to neonatologists. Lack of uniformity and inconsistency in nutrition practices are the most common causes. We started a quality improvement (QI) initiative with an intention to decrease the proportion of EUGR.

Aerobic granular sludge for high-strength ammonium wastewater treatment: Effect of COD/N ratios, long-term stability and nitrogen removal pathways.

Aerobic granular sludge (AGS) technology is increasingly considered for wastewater treatment. AGS stability particularly under lower COD/N ratios is an impediment for AGS technology. This study evaluated AGS stability and nitrogen removal at different loading rates of 0.

Impact of Advocacy, Communication, Social Mobilization and Active Case Finding on TB Notification in Jharkhand, India.

The tests are carried out for low wind velocities ranging from 7 m/s to 10 m/s. The data is acquired using data acquisition system equipped with Labview software and the processed data is represented in terms of non-dimensional parameters, namely power coefficient (C), torque coefficient (C) and tip speed ratio (λ).

Sustainable bioreduction of toxic levels of chromate in a denitrifying granular sludge reactor.

Biological removal of chromate [Cr(VI)] in the presence or absence of nitrate by granular sludge biofilms was investigated in batch experiments and in a sequencing batch reactor (SBR). Denitrifying granular sludge cultivated from activated sludge was able to directly reduce Cr(VI) in the presence of an electron donor. Bioreduction was dependent on the initial Cr(VI) and the granular sludge concentrations.

Aerobic granular sludge technology: Mechanisms of granulation and biotechnological applications.

Aerobic granular sludge (AGS) is a novel microbial community which allows simultaneous removal of carbon, nitrogen, phosphorus and other pollutants in a single sludge system. AGS is distinct from activated sludge in physical, chemical and microbiological properties and offers compact and cost-effective treatment for removing oxidized and reduced contaminants from wastewater. AGS sequencing batch reactors have shown their utility in the treatment of abattoir, live-stock, rubber, landfill leachate, dairy, brewery, textile and other effluents.

Efficient Computation of Small-Molecule Configurational Binding Entropy and Free Energy Changes by Ensemble Enumeration.

Here we present a novel, end-point method using the dead-end-elimination and A* algorithms to efficiently and accurately calculate the change in free energy, enthalpy, and configurational entropy of binding for ligand-receptor association reactions. We apply the new approach to the binding of a series of human immunodeficiency virus (HIV-1) protease inhibitors to examine the effect ensemble reranking has on relative accuracy as well as to evaluate the role of the absolute and relative ligand configurational entropy losses upon binding in affinity differences for structurally related inhibitors. Our results suggest that most thermodynamic parameters can be estimated using only a small fraction of the full configurational space, and we see significant improvement in relative accuracy when using an ensemble versus single-conformer approach to ligand ranking.

Evaluation of antimicrobial, antioxidant and wound-healing potentials of Holoptelea integrifolia.

The methanolic extracts of Holoptelea integrifolia (Roxb.) (Urticaceae) leaves (MLE) and stem bark (MSBE) were studied for the wound-healing potential. Since wound healing is severely hampered by microbial infection and reactive oxygen species (ROS), this study was undertaken to evaluate antimicrobial and antioxidant activity apart from wound-healing activity.

Design of mutation-resistant HIV protease inhibitors with the substrate envelope hypothesis.

There is a clinical need for HIV protease inhibitors that can evade resistance mutations. One possible approach to designing such inhibitors relies upon the crystallographic observation that the substrates of HIV protease occupy a rather constant region within the binding site. In particular, it has been hypothesized that inhibitors which lie within this region will tend to resist clinically relevant mutations.
