Lyophilized Synthetic Platelets: In Vitro Characterization and in Vivo Evaluation in Mouse Thrombocytopenia Model

Advanced Science, EarlyView.
ABSTRACT Platelet transfusions to treat bleeding complications use donor‐derived platelets stored at room‐temperature, that have a shelf‐life of only 5–7 days due to bacterial contamination risks. Cold‐stored and freeze‐dried platelets are being investigated for extending shelf‐life, but these still have the inherent challenge of donor‐dependency.

Comparing Self-Report Pre-Exposure Prophylaxis Adherence Questions to Pharmacologic Measures of Recent and Cumulative Pre-Exposure Prophylaxis Exposure

Frontiers in Pharmacology, 2019
As pre-exposure prophylaxis (PrEP) effectiveness is strongly linked to adherence, we sought to determine if certain self-report measures could be used to inform objective PrEP adherence.

Pre-Exposure Prophylaxis for HIV: Evidence and Perspectives

Current Pharmaceutical Design, 2017
HIV remains an important public health issue worldwide. However, new prevention approaches have recently been developed and are very promising. Antiretroviral treatment as prevention, or as a prophylaxis after exposure to HIV, has been shown to reduce the likelihood of HIV acquisition.

Nanoparticle Encapsulation for Antiretroviral Pre-Exposure Prophylaxis [PDF]

Journal of Nanotechnology and Materials Science, 2017
HIV continues to be one of the greatest challenges facing the global health community. More than 36 million people currently live with HIV and, in 2015 2.1 million new infections were reported globally. Pre-Exposure Prophylaxis (PrEP) prevents HIV infection by inhibiting viral entry, replication, or integration at the primary site of pathogenic ...

Biomimetic Polymerization of Tellurocysteine: Breaking the Natural Amino Acid Radioprotection Limitation

Advanced Science, EarlyView.
Inspired by natural amino acid polymer‐melanin systems, this study strategically incorporated tellurocysteine to develop advanced radiation‐shielding materials. This approach transformed the primary interaction mechanism between melanin‐based materials and incident photons from Compton scattering to the photoelectric effect. Tellurocysteine‐polymerized

A Catalytic Osmium Redox Couple Collapses Cancer Redox Balance

Advanced Science, EarlyView.
A stable Os(III)/Os(IV) redox couple is developed to disrupt the tumor cell redox balance by concurrently catalyzing ROS generation and GSH depletion. Osmium‐treated cells exhibit multiple cell death pathways, including apoptosis, ferroptosis, and immunogenic cell death.

Engineered Carbon Dots from a Traditional Herb Pair Orchestrate Concurrent Antioxidant and AP‐1‐Mediated Inflammation to Attenuate Renal Ischemia‐Reperfusion Injury

Advanced Science, EarlyView.
This study integrates two complementary traditional Chinese medicine components as precursors to synthesize bioactive AM‐AS@CDs. Compared with single‐component CDs, these dual‐component CDs exhibit enhanced antioxidant capacity and superior renoprotective effects.

Exploring Pre-Exposure Prophylaxis (PrEP) and Post-Exposure Prophylaxis (PEP) Knowledge in Incarcerated Men

American Journal of Men's Health, 2022
People who are incarcerated have a disproportionately high risk of contracting human immunodeficiency virus (HIV). While there is no known cure for HIV, there are biomedical approaches that can successfully manage the virus and prevent its transmission ...

Targeting Golgi–STING Signaling to Reprogram Innate and Adaptive Immunity for the Treatment of Implant‐Associated Infections

Advanced Science, EarlyView.
This study presents an ultrasound‐responsive nanoplatform, CS‐BT@MZ@NEs, with a BaTiO3/Mn‐Zif‐8 core and a chondroitin sulfate coating for Golgi targeting. By leveraging neutrophil hitchhiking, it enables targeted delivery to infection sites. Under ultrasound stimulation, CS‐BT@MZ@NEs generates ROS and modulates Golgi pH to activate cGAS–STING ...

Changes in HIV post-exposure prophylaxis prescriptions before and after the introduction of HIV pre-exposure prophylaxis at a sexual health clinic in Melbourne, Australia, 2011–2021

Australian and New Zealand Journal of Public Health
Objective: HIV pre-exposure prophylaxis (PrEP) became available in Victoria, Australia, in 2016. We examined non-occupational post-exposure prophylaxis (nPEP) usage among gay, bisexual and other men who have sex with men (MSM) before and after PrEP ...
