Constraint of Lignin–Carbohydrate Complex Orchestrated on Polyphenol in Oil–Water Interface Targeting Ulcerative Colitis Therapy

Advanced Science, EarlyView.
This study constructed the W1/O/W2 emulsion–based targeted therapy delivery system for ulcerative colitis (UC) utilizing LCC as surfactant for the first time. This multifunctional emulsion offered certain therapeutic advantages for UC, including targeted colonic delivery of active compounds, synergistic modulation of gut microbiota through combined ...

In vitro and ex vivo inhibition of human telomerase by anti-HIV nucleoside reverse transcriptase inhibitors (NRTIs) but not by non-NRTIs.

PLoS ONE, 2012
Telomerase is a specialized reverse transcriptase responsible for the de novo synthesis of telomeric DNA repeats. In addition to its established reverse transcriptase and terminal transferase activities, recent reports have revealed unexpected cellular ...

Incorporation of aptamers in the terminal loop of shRNAs yields an effective and novel combinatorial targeting strategy. [PDF]

, 2017
Gene therapy by engineering patient's own blood cells to confer HIV resistance can potentially lead to a functional cure for AIDS. Toward this goal, we have previously developed an anti-HIV lentivirus vector that deploys a combination of shRNA, ribozyme ...

Pharmacokinetics of dolutegravir, tenofovir and lamivudine during venous–venous extracorporeal membrane oxygenation (VV‐ECMO): A case report

British Journal of Clinical Pharmacology, EarlyView.
While providing potentially life‐saving cardiorespiratory support for critically ill patients, extracorporeal membrane oxygenation (ECMO) may detrimentally affect pharmacokinetic (PK) performance and concurrent drug efficacy and safety. We describe a patient with Pneumocystis jirovecii pneumonia (PJP) in the context of acquired immunodeficiency ...

Diagnosis, antiretroviral therapy, and emergence of resistance to antiretroviral agents in HIV-2 infection: a review

Brazilian Journal of Infectious Diseases
Human immunodeficiency virus type 1 (HIV-1) and type 2 (HIV-2) are the causative agents of AIDS. HIV-2 is prevalent at moderate to high rates in West African countries, such as Senegal, Guinea, Gambia, and Cape Verde.

Twenty-six years of HIV science: an overview of anti-HIV drugs metabolism

Brazilian Journal of Pharmaceutical Sciences, 2011
From the identification of HIV as the agent causing AIDS, to the development of effective antiretroviral drugs, the scientific achievements in HIV research over the past twenty-six years have been formidable.

4′-Acylated thymidine 5′-triphosphates: a tool to increase selectivity towards HIV-1 reverse transcriptase [PDF]

, 2017
4′-Acylated thymidines represent a new class of DNA chain terminators, since they have been shown to act as post-incorporation chain-terminating nucleotides despite the presence of a free 3′-hydroxyl group. Here, we describe the action of the 4′-acetyl- (

The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Pretreatment HIV Drug Resistance and the Molecular Transmission Network Among HIV-Positive Individuals in China in 2022: Multicenter Observational Study

JMIR Public Health and Surveillance, 2023
BackgroundEmerging HIV drug resistance caused by increased usage of antiretroviral drugs (ARV) could jeopardize the success of standardized HIV management protocols in resource-limited settings.

A Mutagenetic Tree Hidden Markov Model for Longitudinal Clonal HIV Sequence Data

, 2006
RNA viruses provide prominent examples of measurably evolving populations. In HIV infection, the development of drug resistance is of particular interest, because precise predictions of the outcome of this evolutionary process are a prerequisite for the ...
