1007/s40857-021-00245-2.Developing countries scramble to contain and mitigate the spread of coronavirus disease 2019 (COVID-19), and world leaders demand equitable distribution of vaccines to trigger economic recovery. Although numerous strategies, including education, quarantine, and immunization, have been used to control COVID-19, the best method to curb this disease is vaccination. Due to the high demand for COVID 19 vaccine, developing countries must carefully identify and prioritize vulnerable populations and rationalize the vaccine allocation process. This study presents a mixed-integer linear programming model for equitable COVID-19 vaccine distribution in developing countries. Vaccines are grouped into cold, very cold, and ultra-cold categories where specific refrigeration is required for their storage and distribution. The possibility of storage for future periods, facing a shortage, budgetary considerations, manufacturer selection, order allocation, time-dependent capacities, and grouping of the heterogeneous population are among the practical assumptions in the proposed approach. Real-world data is used to demonstrate the efficiency and effectiveness of the mathematical programming approach proposed in this study.
SARS-CoV-2 variants of concern (VOC) have been described in the UK (B.1.1.7), South Africa (B.1.351) and Brazil (P.1). Among them, the most scarce information has been obtained from the P.1 variant and more data on its global presence and about its spreading dynamics are needed.

Whole genome sequencing was performed prospectively on travellers arriving from Brasil and on a random selection of SARS-CoV-2 positive cases from our population.

In this study we report the first SARS-CoV-2 P.1 and P.2 variants exported from Brazil to Spain. The case infected with the P.1 variant, who had only stayed in Rio de Janeiro, required hospitalization. The two P.2 cases remained asymptomatic. A wider distribution for P.1 variant beyond the Brazilian Amazonia should be considered. The exportation of the P.2 variant, carrying the E484K mutation, deserves attention.

One month after the first description of P.1 and P.2 importations from Brazil to Madrid, these variants were identified circulating in the community, in cases without a travel history, and involved in household transmissions.

TOFA inhibitor Marginalized and vulnerable tribal communities make approximately 10% of the massive population, playing a dynamic role in this regard. Their ancestral knowledge can be explored to inculcate the ethos in multiple disciplines. This would most certainly bring the much-needed balance in achieving the United Nations Sustainable Development Goals. Where the world is fast losing its natural resources, promoting traditional knowledge (TK) could become an initiative for its reconstruction in post-COVID 19 scenarios. Apart from reinstating the rights of these indigenous communities, this step would also facilitate the economic benefit of the country through the incorporation of TK in the realm of Intellectual Property. This would be a masterstroke for India to lead the Global South. This would also bring in a balance with the Global North, where significant developments have already taken place, in this regard. TK per se should not necessarily be protectable unless based on scientific evidence.In 2000, a controversial article about hormones and gender roles was published to stimulate debate about whether and how biological knowledge should be integrated in sociological research. Two decades later, this so-called biosociology debate is more relevant than ever, as biological knowledge has become widespread across societies and scientific disciplines. Hence, we as sociologists are regularly confronted with biological explanations that challenge our own explanations. Whether this happens in the scientific arena, the classroom, media, or even at social events, these situations often force us, individually, to take a stance on whether to meet such explanations with dialogue or opposition. One could therefore expect that sociologists have an interest in discussing these issues with their peers, but their lack of participation in the biosociology debate suggests otherwise. This paper explores possible reasons for this absence and how sociologists' views on biosociology are influenced by key agents - sociological associations and journals. Smith's "A Sacred project of American Sociology", and Scott's "A Sociology of Nothing" served as theoretical tools in the paper. A qualitative content analysis of presidential addresses of four sociological associations was conducted. The analyses suggest that sociologist avoid biosociology for widely different reasons, including fear that biosociology legitimizes oppression. This avoidance is probably reinforced by the leftish politization of the sociological discipline and the rightish politization of society. Overcoming obstacles to engagement in biosociology is required to safeguard the scientific integrity of sociology and enable sociologists to provide relevant contributions to research on the Covid-19 pandemic and climate change.Super-resolution fluorescence imaging that surpasses the classical optical resolution limit is widely utilized for resolving the spatial organization of biological structures at molecular length scales. In one example, single-molecule localization microscopy, the lateral positions of single molecules can be determined more precisely than the diffraction limit if the camera collects individual photons separately. Using several schemes that introduce engineered optical aberrations in the imaging optics, super-resolution along the optical axis (perpendicular to the sample plane) has been achieved, and single-molecule localization microscopy has been successfully applied for the study of 3D biological structures. Nonetheless, the achievable axial localization accuracy is typically three to five times worse than the lateral localization accuracy. Only a few exceptional methods based on interferometry exist that reach nanometer 3D super-resolution, but they involve enormous technical complexity and restricted sample preparations that inhibit their widespread application.
