Spatial Patterning of Modular Gelatin‐Peroxide Microspheres in Melt‐Electrowritten Scaffolds Provides Controlled Oxygen Generation and Mitigates Hypoxia and Cytotoxicity

open access: yesAdvanced Healthcare Materials, EarlyView.
A bioassembly approach is described using photo‐crosslinked gelatin‐based microgels containing calcium peroxide (CaO2) to generate oxygen (O2) and enhance cell survival in hypoxic conditions (1% O2). Bioassembly enables spatial patterning of individual CaO2‐laden and mesenchymal stem cell (MSC)‐laden microgels and allows for decoupling and mitigating ...

Upregulation of inducible NO synthase by exogenous adenosine in vascular smooth muscle cells activated by inflammatory stimuli in experimental diabetes [PDF]

open access: yes, 2016
BACKGROUND: Adenosine has been shown to induce nitric oxide (NO) production via inducible NO synthase (iNOS) activation in vascular smooth muscle cells (VSMCs). Although this is interpreted as a beneficial vasodilating pathway in vaso-occlusive disorders,

Architecture of an All‐In‐One Microfluidic Platform for Accelerated Cancer Seeding, Enhanced Spheroid Formation, and Dynamic Drug Screening Trials

open access: yesAdvanced Materials Technologies, EarlyView.
An all‐in‐one microfluidic platform consists of two‐layered PDMS channels integrated with a hydrogel microwell array. This platform enables flow‐driven tumor cell capture, enhanced spheroid formation within the microwells, and advective drug testing. ABSTRACT Effective cancer drug screening requires platforms that replicate the physiological complexity

Determination of total potentially available nucleosides in bovine milk [PDF]

open access: yes, 2010
Bovine colostrum and milk samples were collected from two herds over the course of the first month post-partum, pooled for each herd by stage of lactation and total potentially available nucleosides were determined.

Weight gain among treatment-naïve persons with HIV starting integrase inhibitors compared to non-nucleoside reverse transcriptase inhibitors or protease inhibitors in a large observational cohort in the United States and Canada. [PDF]

open access: yes, 2020
IntroductionWeight gain following antiretroviral therapy (ART) initiation is common, potentially predisposing some persons with HIV (PWH) to cardio-metabolic disease.

Biocatalytic Construction of a Chemical Exchange Saturation Transfer Magnetic Resonance Imaging Nucleoside Probe: Synthesis and Evaluation of 5‐Methyl‐5,6‐Dihydrothymidine

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Al‐Hilfi et al. present a biocatalytic strategy for synthesizing 5‐methyl‐5,6‐dihydrothymidine (5‐MDHT), a sensitive MRI contrast agent. The study demonstrates that recombinant enzyme catalysis offers an efficient, sustainable, and eco‐friendly alternative to traditional chemical synthesis for producing clinically relevant imaging probes.

Nucleoside Diphosphate Prodrugs [PDF]

open access: yesNucleic Acids Symposium Series, 2008
Nucleoside analogs are widely applied in antiviral and antitumor therapy. A severe limitation of these compounds arises from the need of biotransformation to the eventually active nucleoside triphosphates by stepwise addition of phosphate by kinases. This problem can be circumvented by employing reversibly masked nucleotides (prodrugs).

Antiretroviral drug resistance mutations in naïve and experienced patients in Shiraz, Iran, 2014 [PDF]

open access: yes, 2016
Resistance to antiretroviral agents is a significant concern in the clinical management of HIV-infected individuals, particularly in areas of the world where treatment options are limited.

Metformin Impairs Breast Cancer Growth through the Inhibition of PRMT6

open access: yesAdvanced Science, EarlyView.
Metformin has a biological activity against breast cancer. However, it is largely unknown about its precise therapeutic targets. Here, histone arginine methyltransferase PRMT6 is identified as a new anti‐cancer target for metformin. Metformin directly binds PRMT6 and inhibits its ability to catalyze histone H3R2 asymmetric dimethylation (H3R2me2a ...

Emergence of highly profibrotic and proinflammatory Lrat+Fbln2+ HSC subpopulation in alcoholic hepatitis

open access: yesHepatology, EarlyView., 2022
Lrat+ quiescent hepatic stellate cells (qHSC) give rise to Lrat+Fbln2+ activated HSC (aHSC) in alcohol‐associated hepatitis and this subpopulation is highly profibrotic, inflammatory, and immunoregulatory based on their single cell transcriptomic profile. Abstract Background and Aims Relative roles of HSCs and portal fibroblasts in alcoholic hepatitis (
