IMPATIENT-qPCR: monitoring SELEX success during in vitro aptamer evolution.

SELEX (Systematic Evolution of Ligands by Exponential enrichment) processes aim on the evolution of high-affinity aptamers as binding entities in diagnostics and biosensing. Aptamers can represent game-changers as constituents of diagnostic assays for the management of instantly occurring infectious diseases or other health threats. Without in-process quality control measures SELEX suffers from low overall success rates.

The Coalition for Epidemic Preparedness Innovations (CEPI) and the Partnerships of Equitable Vaccine Access.

This article highlights and evaluates the role of CEPI and its contribution to global equitable access to COVID-19 vaccines through its established partnerships for vaccine development. The article adds to the understanding of how and when such partnerships can work for public health, especially under emergency citations.

The weakness of senescent dermal fibroblasts.

Skin is the largest human organ with easily noticeable biophysical manifestations of aging. As human tissues age, there is chronological accumulation of biophysical changes due to internal and environmental factors. Skin aging leads to decreased elasticity and the loss of dermal matrix integrity via degradation.

The role of civil society organizations in alcohol control during the COVID-19 pandemic across six countries in Africa.

Background: The differing global trends in alcohol consumption and policy measures implemented during the COVID-19 pandemic warrant a closer look at the actions taken by civil society organisations (CSOs) and community-led efforts to describe how they may influence and accelerate action for change in alcohol control measures. This paper analyses actions undertaken by CSOs at the national and local levels to safeguard communities and improve alcohol control policies during the COVID-19 pandemic in six African countries.

Methods: A cross-sectional survey was distributed via email to CSOs involved in alcohol prevention, outreach and policy development in Kenya, Lesotho, Namibia, South Africa, Tanzania and Zimbabwe.
