PCM-TV-TFV: A Novel Two-Stage Framework for Image Reconstruction from Fourier Data [PDF]

SIAM Journal on Imaging Sciences, 2017
We propose in this paper a novel two-stage Projection Correction Modeling (PCM) framework for image reconstruction from (non-uniform) Fourier measurements. PCM consists of a projection stage (P-stage) motivated by the multi-scale Galerkin method and a correction stage (C-stage) with an edge guided regularity fusing together the advantages of total ...

Diagnostic accuracy of a point‐of‐care urine tenofovir assay, and associations with HIV viraemia and drug resistance among people receiving dolutegravir and efavirenz‐based antiretroviral therapy

Journal of the International AIDS Society, 2023
Introduction Novel point‐of‐care assays which measure urine tenofovir (TFV) concentrations may have a role in improving adherence monitoring for people living with HIV (PLHIV) receiving antiretroviral therapy (ART).

Randomized, placebo controlled phase I trial of safety, pharmacokinetics, pharmacodynamics and acceptability of tenofovir and tenofovir plus levonorgestrel vaginal rings in women.

PLoS ONE, 2018
To prevent the global health burdens of human immunodeficiency virus [HIV] and unintended/mistimed pregnancies, we developed an intravaginal ring [IVR] that delivers tenofovir [TFV] at ~10mg/day alone or with levonorgestrel [LNG] at ~20μg/day for 90 days.

Prevention of vaginal SHIV transmission in macaques by a coitally-dependent Truvada regimen. [PDF]

PLoS ONE, 2012
BACKGROUND: Daily pre-exposure prophylaxis (PrEP) with Truvada (a combination of emtricitabine (FTC) and tenofovir (TFV) disoproxil fumarate (TDF)) is a novel HIV prevention strategy recently found to prevent HIV transmission in men who have sex with men

Infant lung function: criteria for selecting tidal flow–volume loops

ERJ Open Research, 2022
Background Tidal flow–volume (TFV) loops are commonly recorded in infants during sleep, due to the more regular breathing patterns compared to the awake state. Standardised deselection of loops outside pre-specified ranges are based on periods of regular

Linking the Population Pharmacokinetics of Tenofovir and Its Metabolites With Its Cellular Uptake and Metabolism

CPT: Pharmacometrics & Systems Pharmacology, 2014
Empirical pharmacokinetic models are used to explain the pharmacokinetics of the antiviral drug tenofovir (TFV) and its metabolite TFV diphosphate (TFV‐DP) in peripheral blood mononuclear cells.

Improved pharmacokinetics of tenofovir ester prodrugs strengthened the inhibition of HBV replication and the rebalance of hepatocellular metabolism in preclinical models

Frontiers in Pharmacology, 2022
Tenofovir (TFV) ester prodrugs, a class of nucleotide analogs (NAs), are the first-line clinical anti-hepatitis B virus (HBV) drugs with potent antiviral efficacy, low resistance rate and high safety.

Vaginal microbiota and mucosal pharmacokinetics of tenofovir in healthy women using tenofovir and tenofovir/levonorgestrel vaginal rings.

PLoS ONE, 2019
Recent data support that the vaginal microbiota may alter mucosal pharmacokinetics (PK) of topically delivered microbicides. Our team developed an intravaginal ring (IVR) that delivers tenofovir (TFV) (8-10 mg/day) alone or with levonorgestrel (LNG) (20 ...

Hepatitis B surface antigen reduction as a result of switching from long‐term entecavir administration to tenofovir

JGH Open, 2020
Background and Aim Loss of hepatitis B surface antigen (HBsAg) is an important goal in the treatment of chronic hepatitis B. We investigated whether switching from long‐term entecavir (ETV) administration to tenofovir (TFV) (tenofovir alafenamide [TAF ...
