Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Sequential emergence and clinical implications of viral mutants with K70E and K65R mutation in reverse transcriptase during prolonged tenofovir monotherapy in rhesus macaques with chronic RT-SHIV infection. [PDF]

open access: yes, 2007
BackgroundWe reported previously on the emergence and clinical implications of simian immunodeficiency virus (SIVmac251) mutants with a K65R mutation in reverse transcriptase (RT), and the role of CD8+ cell-mediated immune responses in suppressing ...

Implantable Microarray Patch: Engineering at the Nano and Macro Scale for Sustained Therapeutic Release via Synthetic Biodegradable Polymers

open access: yesAdvanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This review focuses on the application of synthetic biodegradable microarray patches (MAPs) in sustained drug delivery. Compared to conventional MAPs which release drugs into the skin in an immediate manner, these implantable MAPs release drugs into skin microcirculation gradually as the biodegradable polymers degrade, thus offering sustained release ...

The Advent Of Cytomegalovirus Infection In HIV Infected Patients: A review [PDF]

open access: yes, 2004
Cytomegalovirus is considered as one among the long list of latent infections in humans that although normally controlled by the cellular immune response, gets activated after HIV infection takes its role on infecting the T4 lymphocytes. Clinical disease

Direct Access to α,β‐Unsaturated γ‐Lactams via Palladium‐Catalysed Carbonylation of Propargylic Ureas.

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Additive carbonylations typically necessitate strong nucleophiles, such as alcohols or amines. In this study, we carbonylated a poorly nucleophilic urea, under oxidant‐free conditions. Our straightforward carbonylative strategy enables access to versatile α,β‐unsaturated γ‐lactams featuring an aminocarbonyl fragment, utilizing readily ...

Opportunities in Therapeutic mRNA Stabilization: Sequence, Structure, Adjuvants and Vectors

open access: yesAdvanced Therapeutics, EarlyView.
Current mRNA lipid nanoparticles rely on cold storage, which increases the cost and reduces access to the vaccines. As mRNA expands to other clinical opportunities, better methods to stabilize the medicines during shipping, storage, and delivery are needed.

Development of Mucoadhesive Gel Microbicide to Target Mucosal HIV Reservoirs [PDF]

open access: yes, 2014
The wide use of microbicide is mainly depends on its effectiveness, less frequent application, ready availability and most importantly cost. The aim of this work was to develop affordable microbicide mucoadhesive gel formulation of synthetic anti HIV ...

Enhanced Epithelial Cell Uptake of Glycol Chitosan‐Coated PLGA Nanoparticles for Oral Drug Delivery

open access: yesAdvanced Therapeutics, EarlyView.
Here, glycol chitosan (GC)‐coated PLGA NPs are developed to enhance oral drug delivery by enabling dual‐pathway endocytosis via clathrin‐ and caveolae‐mediated mechanisms. Alginate layering coating on GC‐PLGA further improves oral insulin delivery, achieving sustained glucose reduction in diabetic mice.
