Lifestyle and behavioral changes during nationwide lockdown in India-A cross-sectional analysis.

INTRODUCTION: After almost two months of reporting the first case of the novel coronavirus disease (COVID-19) in the country, the nationwide lockdown in India was initiated on 24th of March 2020, to curtail the spread of the SARS-CoV-2 infection in the country. While this lockdown had been in place for almost 3 months, the people of the nation have experienced changes in their routine lives in a wide range of activities, including personal behaviours. This study was conducted to identify the impacts that the lockdown had on the lifestyle and behavioural aspects of Indians during the lockdown. METHODS: It was a cross sectional study, conducted by online survey. Data collection was done for the period of 3 months. RESULTS: The study found that a huge number of participants had significant changes in their diet, sleep, bowel habits and also their personal traits. Also, the lockdown had improved interpersonal relationships and helped people explore their hobbies or even acquire a new skill (about 25% of the participants). More than 90% of the participants perceived decrease in air pollution and a majority reported increase in personal hygiene (74.2%), perceived decrease in crime rates (67.3%) as benefits of lockdown. CONCLUSIONS: It would be recommended to include variables to screen for mental health issues among the general population.

Modeling protein association from homogeneous to mixed environments: A reaction-diffusion dynamics approach.

Protein-protein association in vivo occur in a crowded and complex environment. Theoretical models based on hard-core repulsion predict stabilization of the product under crowded conditions. Soft interactions, on the contrary, can either stabilize or destabilize the product formation. Here we modeled protein association in presence of crowders of varying size, shape, interaction potential and used different mixing parameters for constituent crowders to study the influence on the association reaction. It was found that size is a more dominant factor in crowder-induced stabilization than the shape. Furthermore, in a mixture of crowders having different sizes but identical interaction potential, the change of free energy is additive of the free energy changes produced by individual crowders. However, the free energy change is not additive if two crowders of same size interact via different interaction potentials. These findings provide a systematic understanding of crowding influences in heterogeneous medium.
