Valuing burden of premature mortality attributable to air pollution in major million-plus non-attainment cities of India.

Accelerating growth due to industrialization and urbanization has improved the Indian economy but simultaneously has deteriorated human health, environment, and ecosystem. In the present study, the associated health risk mortality (age > 25) and welfare loss for the year 2017 due to excess PM concentration in ambient air for 31 major million-plus non-attainment cities (NACs) in India is assessed. The cities for the assessment are prioritised based on population and are classified as 'X' (> 5 million population) and 'Y' (1-5 million population) class cities.

Stop Four Gaps with One Bush: Versatile Hierarchical Polybenzimidazole Nanoporous Membrane for Highly Durable Li-S Battery.

Lithium-sulfur (Li-S) batteries are considered as one of the most prospective candidates for electric vehicles, due to their superior theoretical energy density and low cost. However, the issues of polysulfide ion (PS) shuttling and uncontrollable Li dendrite growth hindered their further application. Herein, a multifunctional nanoporous polybenzimidazole (PBI) membrane with well-controllable morphology was successfully designed and fabricated to address the aforementioned obstacles.

Interferon-induced central retinal vein thrombosis.

A middle-aged lady presented with sudden onset of unilateral central retinal vein thrombosis after completing 6 months course of interferon and ribavirin for chronic hepatitis C infection. She had no risk factors and all her thrombophilia workup was normal, however, she was found to be dyslipidemic which may have contributed to atherosclerosis and predispose to thrombosis. Despite anticoagulation, her visual acuity deteriorated.
