Anthocyanin Identification of Methanol-HCl Extract Active Fraction in Rosella (Hibiscus Sabdariffa. L) and Its Potential as Xanthine Oxidase Inhibitor [PDF]

open access: yes, 2014
The active fraction of methanol-HCl extract of Roselle flower (Hibiscus sabdariffa. L) has been identified and its inhibitor xanthine oxidase potential tested. The aim of this study was to compare the inhibitory activity of xanthine oxidase from methanol-

Calciprotein particle‐induced calcium overload triggers mitochondrial dysfunction in endothelial cells

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Calciprotein particles (CPPs) are small calcium‐ and phosphate‐containing nanoaggregates associated with the development of vascular disease (CVD) in chronic kidney disease (CKD). Previously, we have shown that CPPs induce endothelial cell (EC) dysfunction, possibly contributing to CVD in CKD, but the underlying molecular ...

Research and development of non-enzymatic electrochemical sensors utilizing porous ZnO/graphene electrodes to determine xanthine

open access: yesTạp chí Kiểm nghiệm và An toàn thực phẩm
In this study, we developed a non-enzymatic electrochemical sensor using a porous graphene electrode modified with ZnO nanoparticles (ZnO/fPGE sensor) to determine xanthine (XA) content.

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Model‐Based Strategy for 6‐Mercaptopurine Treatment in Acute Lymphoblastic Leukemia Maintenance Phase: Prediction of 6‐TGN and 6‐MMP Concentrations to Optimize Treatment

open access: yesPediatric Blood &Cancer, Volume 73, Issue 4, April 2026.
ABSTRACT Introduction Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer. The pro‐drug 6‐mercaptopurine (6‐MP), essential during maintenance, is converted into active 6‐thioguanine (6‐TGN) and toxic 6‐methylmercaptopurine (6‐MMP) metabolites, resulting in marked variability in efficacy and toxicity.

Potential Hypoglycemic, Hypolipidemic, and Hypouricemic Bioactive Components From Ampelopsis grossedentata Explored by Affinity Ultrafiltration With Three Enzyme Targets

open access: yeseFood, Volume 7, Issue 2, April 2026.
By integrating bioaffinity ultrafiltration coupled with HPLC‐MS/MS, this study identified quercetin, myricetrin, dihydromyricetin, and taxifolin from Ampelopsis grossedentata as key inhibitors of α‐glucosidase, pancreatic lipase, and xanthine oxidase, highlighting the promising potential of A.

Potential to Improve Nitrogen Fertilizer Use Efficiency and Mitigate Pollution in Tropical Pastures Grazed by Sheep

open access: yesNew Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
We hypothesize that increasing N application rates will affect N use efficiency (NUE) for lambs grazing warm‐season annual grasses. We evaluated the effect of N fertilizer application rates (50, 100, 200, and 400 kg N/ha) on forage pearl millet (Pennisetum glaucum (L.) R.) and animal responses: N balance and NUE per animal and per area basis.

Differential Analysis of IAA Anabolism Pathway Based on Bacillus cereus, Bacillus subtilis and Bacillus safensis Genome

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Three Bacillus species isolated from Platycladus orientalis rhizosphere in Taihang Mountains: Bacillus cereus has 3 IAA synthesis pathways (TAM, IAM, IPyA); Bacillus subtilis has IAM/IPyA; and Bacillus safensis only has IPyA (via whole‐genome sequencing).
