Immunocompromised Status Definition in Observational Studies Using Electronic Health Records: A Scoping Review and a Proposal for a Phenotype Identification Algorithm

open access: yesPharmacoepidemiology and Drug Safety, Volume 35, Issue 4, April 2026.
ABSTRACT Immunocompromised individuals experience an impaired immune function due to conditions that might be either congenital or acquired over the course of their lives. Epidemiological studies often rely on clinical definitions which, in some cases, benefit from being translated into machine‐readable algorithms for application to electronic health ...

Mycoplasmas and cancer [PDF]

open access: yes, 2014
The standard of care for patients suffering cancer often includes treatment with nucleoside analogues (NAs). NAs are internalized by cell-specific nucleobase/nucleoside transporters and, after enzymatic activation (often one or more phosphorylation steps)

Pinpointing dynamic coupling in enzymes for efficient drug design [PDF]

open access: yes, 2016
Enzymes are proteins that catalyze almost every chemical reaction in living systems, achieving rate enhancements of up to 21 orders of magnitude relative to the uncatalyzed reactions.

A Simple Method for RNA‐Seq of Manually Isolated Chromatophores in Oryzias Fishes

open access: yesDevelopment, Growth &Differentiation, Volume 68, Issue 3, April 2026.
ABSTRACT RNA sequencing (RNA‐seq) has become an essential tool for analyzing gene expression and exploring cell type–specific transcriptomes. However, sample preparation and quality control remain challenging, as current approaches typically rely on dissecting tissues containing mixed cell populations or using flow cytometry to isolate fluorescently ...

The cytokinesis regulator RacGAP1 is a Rac1‐specific GAP on membranes

open access: yesProtein Science, Volume 35, Issue 3, March 2026.
Abstract Rho family small GTPases are essential for cytokinesis completion. RacGAP1, a dimeric multidomain protein with a lipid‐binding C1 domain and a GTPase‐activating protein (GAP) domain, is a major regulator in this process. However, despite many cellular and biochemical studies, whether RhoA or Rac1 is the actual substrate inactivated by RacGAP1 ...

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, Volume 368, Issue 1, January 2026.
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.

Tri-Cyclic Nucleobase Analogs and Their Ribosides as Substrates of Purine-Nucleoside Phosphorylases. II Guanine and Isoguanine Derivatives

open access: yesMolecules, 2019
Etheno-derivatives of guanine, O6-methylguanine, and isoguanine were prepared and purified using standard methods. The title compounds were examined as potential substrates of purine-nucleoside phosphorylases from various sources in the reverse ...

A Rapid Colorimetric Method for Determining Calcium, Inorganic Phosphorus, and Zinc in Human Milk Using Clinical Laboratory Reagents

open access: yesJournal of Clinical Laboratory Analysis, Volume 40, Issue 2, January 2026.
We evaluated a colorimetric assay using clinical reagents for determining Ca, IP, and Zn in human milk. Significant correlations were observed between Ca, IP, and Zn levels determined by colorimetric assay and Ca, total P, and Zn levels determined by ICP‐AES.
