CD49a expression defines a metabolically robust, cytokine‐biased liver NK cell subset in rhesus macaques during lentivirus infection

Immunology &Cell Biology, Volume 104, Issue 7, Page 656-666, August 2026.
Liver‐resident NK cells (CD49a+ NK cells) in rhesus macaques display distinct activating receptor and metabolic markers enhanced phenotype compared with hepatic NK cell subsets (CD49a−) in the liver. These cells exhibit heightened cytokine polyfunctionality with restrained cytotoxic responses upon mitogen stimulation in comparison with CD49a− NK cell ...

Behavioural and Structural Determinants of Mpox Vaccine Awareness and Uptake Among People With HIV in the Dominican Republic: A Cross‐Sectional Study

Journal of the International AIDS Society, Volume 29, Issue S2, July 2026.
ABSTRACT Introduction Mpox disproportionately affects people with HIV (PWH), yet little is known about mpox vaccine awareness and uptake in low‐ and middle‐income countries. We evaluated mpox‐related knowledge, attitudes and practices (KAP) among PWH in the Dominican Republic to identify determinants of vaccine awareness and uptake.

CFAR Ship Detection in Polarimetric Synthetic Aperture Radar Images Based on Whitening Filter [PDF]

, 2020
Polarimetric whitening filter (PWF) can be used to filter polarimetric synthetic aperture radar (PolSAR) images to improve the contrast between ships and sea clutter background. For this reason, the output of the filter can be used to detect ships.

Robust Control for the Detection Threshold of CFAR Process in Cluttered Environments

Sensors, 2020
The constant false alarm rate (CFAR) process is essential for target detection in radar systems. Although the detection performance of the CFAR process is normally guaranteed in noise-limited environments, it may be dramatically degraded in clutter ...

The Caribbean, Central and South America Network for HIV Epidemiology: 20 Years of HIV Research in the Region

Journal of the International AIDS Society, Volume 29, Issue S3, July 2026.
ABSTRACT Introduction Latin America is a key region in advancing efforts to end the HIV epidemic globally. Despite breakthroughs in HIV treatment and prevention in the last 20 years, as well as region‐wide improvements in health infrastructure and policies, there has been a 13% increase in new acquisitions in Latin America from 2010 to 2024.

HIV Infection and Opioid Treatment Enable the Engraftment of Kaposi Sarcoma‐Like Tumors Into Immunocompetent Mice

Journal of Medical Virology, Volume 98, Issue 7, July 2026.
ABSTRACT The Kaposi Sarcoma herpesvirus (KSHV) causes Kaposi sarcoma (KS), primary effusion lymphoma, a lymphoproliferative disease (KSHV‐multicentric Castleman's disease), and a cytokine inflammatory syndrome (KICS). These diseases occur more frequently, though not exclusively, among people living with HIV or other types of immune dysregulation. While

Perceptions of Buprenorphine With Naloxone Treatment and the Fear of Precipitated Withdrawal: A Qualitative Exploration With HIV Prevention Trials Network 094 INTEGRA Participants and Staff

Drug and Alcohol Review, Volume 45, Issue 5, July 2026.
ABSTRACT Introduction Uptake of evidence‐based medication for opioid use disorder (MOUD), including buprenorphine–naloxone, remains low despite the expanding US opioid crisis. This study examined participants' and staff perceptions of adopting and delivering buprenorphine–naloxone on a mobile unit providing integrated MOUD and HIV services for people ...
