Full-Thickness Perfused Skin-on-a-Chip with In Vivo-Like Drug Response for Drug and Cosmetics Testing.

In this study, we present a novel 3D perfused skin-on-a-chip model fabricated using micro-precision 3D printing, which offers a streamlined and reproducible approach for incorporating perfusion. Perfused skin models are well-regarded for their advantages, such as improved nutrient supply, enhanced barrier function, and prolonged tissue viability. However, current models often require complex setups, such as self-assembled endothelial cells or sacrificial rods, which are prone to variability and time-consuming.

Utility of "Acanthosis Nigricans" and "Skin Tags" as a screening tool for risk of developing noncommunicable diseases: A cross-sectional study at a health facility in Lucknow (India).

Context: Over the past three decades, there has been a significant rise in the prevalence of noncommunicable diseases (NCDs) globally, accompanied by a relative decline in communicable diseases.

Aims: With this background, the research was planned to determine the prevalence of acanthosis nigricans (AN) or skin tags (STs) in the study population and to examine the relationship between the presence of AN and ST with commonly used indicators such as waist-to-height ratio (W/Ht.), Indian Diabetes Risk Score (IDRS), and body mass index for predicting the risk of NCDs.
