A quantum mechanical analysis of the light-harvesting complex 2 from purple photosynthetic bacteria. Insights into the electrostatic effects of transmembrane helices

, 2010
We perform a quantum mechanical study of the peptides that are part of the LH2 complex from Rhodopseudomonas acidophila, a non-sulfur purple bacteria that has the ability of producing chemical energy from photosynthesis.

Sex‐dependent effects of a high‐fat diet‐induced obesity model on cerebrovascular health and brain metabolism

Experimental Physiology, EarlyView.
Abstract Mid‐life obesity is a major risk factor for neurodegenerative diseases, with mitochondrial and cerebrovascular dysfunction considered key mediators. Lysine acetylation is a reversible post‐translational modification that regulates several mitochondrial metabolic and biochemical processes.

Effect of Ubiquinol supplementation on ovulation induction in Clomiphene Citrate resistance

Middle East Fertility Society Journal, 2021
Background Clomiphene Citrate is considered the gold-standard for induction of ovulation and has been used for several years to treat PCOS related infertility. Unfortunately, 15-40% of women with PCOS are resistant to Clomiphene Citrate.

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

The 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 ...

Crystallographic studies of the Escherichia coli quinol-fumarate reductase with inhibitors bound to the quinol-binding site [PDF]

, 2002
The quinol-fumarate reductase (QFR) respiratory complex of Escherichia coli is a four-subunit integral-membrane complex that catalyzes the final step of anaerobic respiration when fumarate is the terminal electron acceptor.

A Model of Aerobic and Anaerobic Metabolism of Hydrogen in the Extremophile Acidithiobacillus ferrooxidans

Frontiers in Microbiology, 2020
Hydrogen can serve as an electron donor for chemolithotrophic acidophiles, especially in the deep terrestrial subsurface and geothermal ecosystems. Nevertheless, the current knowledge of hydrogen utilization by mesophilic acidophiles is minimal.

Intra‐Tissue Bacteriome and Cellular Profiles in Periodontal Granulation Tissue From Osseous Defects and Extraction Sockets

Journal of Clinical Periodontology, Volume 53, Issue 5, Page 806-820, May 2026.
ABSTRACT Aim To investigate the intra‐tissue bacteriome and cell profiles within periodontal granulation tissue (PGT) for exploring the biological essence and translational potentials. Materials and Methods PGT samples were collected from 49 patients with severe periodontitis—including those from osseous defects (GT) during periodontal surgery ...

BPM31510 Increases the CoQ Pool in Chemically Induced CoQ‐Deficient Cells, CoQ‐Deficient Patient Fibroblasts, and in Metabolically Active Murine Tissues

The FASEB Journal, Volume 40, Issue 7, 15 April 2026.
Graphical abstract illustrating the in vitro and in vivo experimental workflow used to compare BPM31510, a nanoliposomal formulation of oxidized CoQ10, with conventional CoQ10. Chemically induced CoQ‐deficient SH‐SY5Y cells, CoQ‐deficient patient fibroblasts, and C57BL/6J mice receiving oral CoQ10 or intraperitoneal BPM31510 were subjected to plasma ...

Ferroptotic neurodegeneration and diet: a narrative review

Alzheimer's &Dementia, Volume 22, Issue 4, April 2026.
Dietary regimes and separate components have been reported to reduce ferroptosis by (1) altering iron metabolism, (2) increasing antioxidant defense, and (3) reducing lipid peroxidation. This ultimately leads to reduced ferroptosis and neurodegeneration.

Analysis of acid-stressed Bacillus cereus reveals a major oxidative response and inactivation-associated radical formation [PDF]

, 2010
Acid stress resistance of the food-borne human pathogen Bacillus cereus may contribute to its survival in acidic environments, such as encountered in soil, food and the human gastrointestinal tract. The acid stress responses of B.
