Metabolic alterations in human pulmonary artery smooth muscle cells treated with PDGF‐BB

open access: yesAnimal Models and Experimental Medicine, Volume 8, Issue 7, Page 1268-1276, July 2025.
Metabolic abnormalities are considered to play a key regulatory role in vascular remodeling of pulmonary arterial hypertension. We analyzed the metabolome in the culture supernatants of human pulmonary artery smooth muscle cells (PASMC) during the malignant proliferation phenotype transition via a targeted metabolomics method. Significant and extensive

Virtual twin approach using physiologically based pharmacokinetic modelling in hospitalized patients treated with apixaban or rivaroxaban

open access: yesBritish Journal of Clinical Pharmacology, Volume 91, Issue 7, Page 2057-2069, July 2025.
Abstract Aims In a large cohort of hospitalized patients, previously validated physiologically based pharmacokinetic (PBPK)‐based models for apixaban and rivaroxaban are being assessed for their performance in predicting individual pharmacokinetics, aiming to identify patients at high risk of under‐ or overdosing based on demographic, physiological and

Vitamin B6 Group. XV. Urinary Excretion of Pyridoxal, Pyridoxamine, Pyridoxine, and 4-Pyridoxic Acid in Human Subjects.

open access: yesExperimental Biology and Medicine, 1949
SummaryThe known metabolic products of vitamin B6—pyridoxal, pyridoxamine, pyridoxine and pyridoxic acid—were measured in normal human urine and in the urine of human subjects each fed one of the 3 forms of the vitamin.The chief product found, regardless of the form fed, was pyridoxic acid.

Catalytic Activities of Pyridoxal Analogues. I. The Catalytic Effects of Pyridoxal, Pyridoxal Methochloride, and Pyridoxal N-Oxide on the Racemization of l-Glutamic Acid [PDF]

open access: yesBulletin of the Chemical Society of Japan, 1975
Abstract An improved method for the syntheses of pyridoxal methochloride (1) and pyridoxal N-oxide (5) was investigated. Further, the catalytic activities of pyridoxal, 1, and 5 on the racemization of l-glutamic acid in the presence of cupric ions were studied.

Amaranthus spinosus Linn. Extract as an Innovative Strategy to Regulate Biomarkers for Ovarian Hyperthecosis via Circular RNA (hsa‐circ‐0001577): Evidence From Biochemical, Metabolomics, Histological, and Phytochemical Profiling

open access: yesFood Science &Nutrition, Volume 13, Issue 5, May 2025.
A significant improvement in hormonal and oxidative stress biomarkers was observed in rats treated with Amaranthus spinosus, especially at high doses, after induction of ovarian hyperthecosis. Amaranthus spinosus could be a management approach for ovarian hyperthecosis via regulating circRNA (hsa‐circ‐0001577), disturbed hormonal balance, and ...

Riktad metabolomik med 'Ultra Performans' Vätskekormatografi Mass Spekrometri (UPLC-MS) visar metaboliska skillnader i hälsosamma samt atopiska Staffordshire bullterrier efter två olika dieter : en pilotstudie [PDF]

open access: yes, 2021
While anecdotal evidence has long claimed that a raw meat–based diet (RMBD) improves the metabolic health of canines, no rigorous scientific study has clarified this issue.

Comprehensive and quantitative profiling of B vitamins and related compounds in the mammalian liver [PDF]

open access: yes, 2020
A method for the simultaneous quantification of B vitamins and related amines in one-carbon (1C) metabolism would benefit the study of diet and genetic/epigenetic regulation of mammalian development and health.

Endogenous and xenobiotic metabolic stability of primary human hepatocytes in long-term 3D spheroid cultures revealed by a combination of targeted and untargeted metabolomics [PDF]

open access: yes, 2017
Adverse reactions or lack of response to medications are important concerns for drug development programs. However, faithful predictions of drug metabolism and toxicity are difficult because animal models show only limited translatability to humans ...

Reaction of pyridoxal-5′-phosphate with γ-carboxyglutamic acid [PDF]

open access: yesExperientia, 1980
Pyridoxal-5′-phosphate (PLP) reacts with γ-carboxyglutamic acid (Gla) to form a stable complex absorbing at 325 nm. It is suggested that a condensation occurs in which the formyl group of PLP reacts with the α-amino group and the γ carbon atom of Gla to give a pyrrolidine derivative.
