<p>The latest outbreak of a new pathogenic coronavirus (SARS-CoV-2) is provoking a global health, economic and societal crisis. All-atom simulations enabled us to uncover the key molecular traits underlying the high affinity of SARS-CoV-2 spike glycoprotein towards its human receptor, providing a rationale to its high infectivity. Harnessing this knowledge can boost developing effective medical countermeasures to fight the current global pandemic.</p>

Structural Aspects

In 2019, an outbreak occurred which resulted in a global pandemic. The causative agent of this serious global health threat was a coronavirus similar to the agent of SARS, referred to as SARS-CoV-2. In this work an analysis of the available structures of the SARS-CoV-2 main protease has been performed. From a data set of crystallographic structures the dynamics of the protease has been obtained. Furthermore, a comparative analysis of the structures of SARS-CoV-2 with those of the main protease of the coronavirus responsible of SARS (SARS-CoV) was carried out. The results of these studies suggest that, although main proteases of SARS-CoV and SARS-CoV-2 are similar at the backbone level, some plasticity at the substrate binding site can be observed. The consequences of these structural aspects on the search for effective inhibitors of these enzymes are discussed, with a focus on already known compounds. The results obtained show that compounds containing an oxirane ring could be considered as inhibitors of the main protease of SARS-CoV-2.

A novel, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causes severe acute respiratory syndrome and spread globally from Wuhan, China. In March 2020 the World Health Organization declared the SARS-Cov-2 virus as a COVID- 19, a global pandemic. This pandemic happened to be followed by some restrictions, and specially lockdown playing the leading role for the people to get disassociated with their personal and social schedules. And now the food is the most necessary thing to take care of. It seems the new challenge for the individual is self-isolation to maintain themselves on the health basis and fight against the pandemic situation by boosting their immunity. Food organised by proper diet may maintain the physical and mental health of the individual. Ayurveda aims to promote and preserve the health, strength and the longevity of the healthy person and to cure the disease by properly channelling with and without Ahara. In Ayurveda, diet (Ahara) is considered as one of the critical pillars of life, and Langhana plays an important role too. This article will review the relevance of dietetic approach described in Ayurveda with and without food (Asthavidhi visheshaytana & Lanhgan) during COVID-19 like a pandemic.

Wuhan originated Covid-19 disease is caused by SARC-COV 2 virus. It is a contagious disease it spread all over the world. World health organization declared a global pandemic disease. In Covid-19 immunity plays an important role. In old age people or having other co-morbid conditions the mortality rate is more. Ayurveda has a big role in improved immunity or to intact immunity. The principle of Ayurveda is to keep individual swastha (diseases free). To maintain individual disease-free Ritucharya is one of the important subjects of Ayurveda. Aimed of study is to find out Ritucharya literature from the Ayurveda and modern research specifically Varsha and Sharad ritu. Ritucharya contains dietary regimen, living modification, common medicine, and contraindicated things those changing according to environmental change. Upcoming season in India is Varsha and Sharad ritu. Environmental changes are huge in this season and it directly affected human beings. So this study reveals property of ritu, dietary regimen, living modification, common medicine and contraindicated things in upcoming varsha and sharad ritu.

Psychological Studies

That American and European participants are overrepresented in psychological studies has been previously established. In addition, researchers also often tend to be similarly homogenous. This continues to be alarming, especially given that this research is being used to inform policies across the world. In the face of a global pandemic where behavioral scientists propose solutions, we ask who is conducting research and on what samples. Forty papers on COVID-19 published in PsyArxiV were analyzed; the nationalities of the authors and the samples they recruited were assessed. Findings suggest that an overwhelming majority of the samples recruited were from the US and the authors were based in US and German institutions. Next, men constituted a large proportion of primary and sole authors. The implications of these findings are discussed.

The One

Motor learning experiments are typically run in-person, exploiting finely calibrated setups (digitizing tablets, robotic manipulandum, full VR displays) that provide high temporal and spatial resolution. However, these experiments come at a cost, not limited to the one-time expense of purchasing equipment but also the substantial time devoted to recruiting participants and administering the experiment. Moreover, exceptional circumstances that limit in-person testing, such as a global pandemic, may halt research progress. These limitations of in-person motor learning research have motivated the design of OnPoint, an open-source software package for motor control and motor learning researchers. As with all online studies, OnPoint offers an opportunity to conduct large-N motor learning studies, with potential applications to do faster pilot testing, replicate previous findings, and conduct longitudinal studies (GitHub repository: https://github.com/alan-s-lee/OnPoint).
