New study examines dermal injections and their impact on skin agingChronic exposure of human skin to ultraviolet light causes premature aging, or photoaging. As the skin undergoes photoaging, type I collagen bundles, which are found in the dermis beneath the top layer of the skin and provide strength and support to skin, become fragmented. This leads to wrinkles, fragility and... Read more

New trial highlights incremental progress towards a cure for HIV-1Antiretroviral therapies (ART) stop HIV replication in its tracks, allowing people with HIV to live relatively normal lives. However, despite these treatments, some HIV still lingers inside cells in a dormant state known as "latency." If ART is discontinued, HIV will awaken from its dormant state, begin to replicate, and... Read more
