Understanding and Mitigating the Risk of Accelerated Biological Aging in Survivors of Cancer: A Scoping Review

Aging and Cancer, EarlyView.
Cancer treatment is associated with measurable acceleration of biological aging across epigenetic, telomere, senescence, and immune biomarkers. However, biomarker validation and interventional strategies remain limited, especially in hematologic malignancies, underscoring the need for standardized multi‐omic aging assessments and adequately powered ...

Drug resistance mutations in drug-naive HIV type 1 subtype C-infected individuals from rural Malawi. [PDF]

, 2010
In this preliminary study we show that in 2008, 3 years after antiretroviral therapy was introduced into the Karonga District, Malawi, a greater than expected number of drug-naive individuals have been infected with HIV-1 subtype C virus harboring major ...

The Role of Ultra‐Thin Passive Films and Organic Adsorbates on Aluminum Chips for a Friction‐Induced Solid‐State Recycling Process

Advanced Engineering Materials, EarlyView.
Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.

Pretreatment HIV Drug-resistance Surveillance as a Tool for Monitoring and Control of the HIV/AIDS Epidemic in Cuba

MEDICC Review, 2021
L'épidémie de VIH/sida est une menace permanente pour la santé publique. Son élimination nécessite de plus grands efforts pour élargir la couverture, la disponibilité et la personnalisation du traitement antirétroviral. La résistance aux médicaments contre le VIH est actuellement un problème mondial en raison de son augmentation continue ces dernières ...
