Exploring the Ascorbate Requirement of the 2-Oxoglutarate-Dependent Dioxygenases.

J Med Chem

January 2025

Ma̅tai Ha̅ora - Centre for Redox Biology and Medicine, Department of Biomedical Science and Pathology, University of Otago, Christchurch, Christchurch 8140, New Zealand.

In humans, the 2-oxoglutarate-dependent dioxygenases (2-OGDDs) catalyze hydroxylation reactions involved in cell metabolism, the biosynthesis of small molecules, DNA and RNA demethylation, the hypoxic response and the formation of collagen. The reaction is catalyzed by a highly oxidizing ferryl-oxo species produced when the active site non-heme iron engages molecular oxygen. Enzyme activity is specifically stimulated by l-ascorbic acid (ascorbate, vitamin C), an effect not well mimicked by other reducing agents.

A π-Extended AIE Platform for Pattern Recognition of Glycosaminoglycans.

Anal Chem

January 2025

Department of Chemistry, College of Sciences, Nanjing Agricultural University, Nanjing, Jiangsu 210095, People's Republic of China.

Accurate discrimination of complicated glycosaminoglycans is a challenging but meaningful task for ensuring their safe use in clinics. With the purpose of reducing the production cost of sensor arrays for glycosaminoglycans, three fluorescence turn-on sensors named , , and were readily synthesized by simple alkylation of the pyridyl units of the π-extended AIEgen, namely, tetra-(4-pyridylphenyl) ethylene. The designed sensors are cross-reactive toward tested glycosaminoglycans including heparin, chondroitin sulfate, hyaluronic acid, and dextran sulfate, whose mechanism could be ascribed to the multivalent electrostatic, CH···π, and hydrophobic interactions between the sensors and different glycosaminoglycans to form corresponding fluorescent aggregates.

Chimeric antigen receptor (CAR) T-cell products axicabtagene ciloleucel (axi-cel), tisagenlecleucel (tisa-cel), and lisocabtagene maraleucel (liso-cel) are approved for relapsed/refractory large B-cell lymphoma (R/R LBCL). Emerging evidence indicates that delayed CAR T-cell infusion, including prolonged time from leukapheresis to infusion, known as vein-to-vein time (V2Vt), may adversely impact clinical outcomes. We conducted a systematic literature review (SLR) and meta-analysis to identify differences in V2Vt in patients with R/R LBCL treated with axi-cel, tisa-cel, or liso-cel.

Serial Total Bile Acid Measurements in Intrahepatic Cholestasis of Pregnancy.

Obstet Gynecol

January 2025

Department of Obstetrics, Gynecology and Reproductive Science, University of California, San Diego, San Diego, California; and the Department of Obstetrics, Gynecology and Reproductive Science, Mount Sinai Health System & Icahn School of Medicine at Mount Sinai, New York, and the Department of Obstetrics, Gynecology and Reproductive Science, New York City Health and Hospitals - Elmhurst Hospital Center, Elmhurst, New York.

Although peak serum total bile acid (TBA) levels guide management of intrahepatic cholestasis of pregnancy (ICP), whether ICP progresses in severity and when or how to assess bile acid levels serially remains unclear. We conducted a secondary analysis of a single-institution retrospective cohort study to assess bile acid trends across pregnancy among individuals diagnosed with ICP and to evaluate whether there was progression to higher ICP severity. We defined ICP severity as mild (peak TBA less than 40 micromol/L), moderate (peak TBA between 40 and 100 micromol/L), or severe (peak TBA 100 micromol/L or greater).

In plasma, the zymogens factor XII (FXII) and prekallikrein reciprocally convert each other to the proteases FXIIa and plasma kallikrein (PKa). PKa cleaves high-molecular-weight kininogen (HK) to release bradykinin, which contributes to regulation of blood vessel tone and permeability. Plasma FXII is normally in a "closed" conformation that limits activation by PKa.

J Med Internet Res

January 2025

Department High-Tech Business and Entrepreneurship Section, Industrial Engineering and Business Information Systems, University of Twente, Enschede, Overijssel, Netherlands.

Health recommender systems (HRS) have the capability to improve human-centered care and prevention by personalizing content, such as health interventions or health information. HRS, an emerging and developing field, can play a unique role in the digital health field as they can offer relevant recommendations, not only based on what users themselves prefer and may be receptive to, but also using data about wider spheres of influence over human behavior, including peers, families, communities, and societies. We identify and discuss how HRS could play a unique role in decreasing health inequities.
