Chemical magnetoreception: bird cryptochrome 1a is excited by blue light and forms long-lived radical-pairs. [PDF]

PLoS ONE, 2007
Cryptochromes (Cry) have been suggested to form the basis of light-dependent magnetic compass orientation in birds. However, to function as magnetic compass sensors, the cryptochromes of migratory birds must possess a number of key biophysical ...

Response of an Infant With Presumed Multiple Acyl‐CoA Dehydrogenase Deficiency (MADD) to Ketone Supplementation

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Multiple Acyl‐CoA Dehydrogenase Deficiency (MADD) is an autosomal recessive inborn error of metabolism caused by biallelic pathogenic variants in one of three known genes: ETFA, ETFB, and ETFDH. It can cause multisystem dysfunction, including cardiomyopathy in severe cases.

Optical redox imaging of ANT1-deficient muscles

Journal of Innovative Optical Health Sciences
Adenine nucleotide translocator (ANT) is a mitochondrial protein involved in the exchange of ADP and ATP across the mitochondrial inner membrane. It plays a crucial role in cellular energy metabolism by facilitating the transport of ATP synthesized ...

Chronic Hypoxia Enhances β-Oxidation-Dependent Electron Transport via Electron Transferring Flavoproteins

Cells, 2019
Hypoxia poses a stress to cells and decreases mitochondrial respiration, in part by electron transport chain (ETC) complex reorganization. While metabolism under acute hypoxia is well characterized, alterations under chronic hypoxia largely remain ...

Immune Modulatory Therapy for Severe Dengue Hemorrhagic Fever in a Patient With Mitochondrial Complex I Deficiency: A Case Report

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Dengue virus (DENV) poses a serious global health challenge, particularly in cases of dengue hemorrhagic fever (DHF). Patients with preexisting mitochondrial disorders may be at increased risk for complications due to the specific impact of DENV on mitochondrial‐dependent cellular processes and immune function.

Quantum Phenomena in Molecular and Biological Systems: A Decoherence‐Based Decision Framework With Falsifiable Predictions and a Failure‐Mode Taxonomy

Advanced Physics Research, EarlyView.
A physics‐grounded framework based on decoherence timescales (τ_dec vs τ_func), Markovian validity, and falsifiability criteria is applied across molecular systems to distinguish where quantum effects are necessary, marginal, or irrelevant. The analysis integrates quantum chemistry, biological quantum mechanisms, and quantum computing under a unified ...

Disulfide Bond–Modified Proteomics Reveals the Effects of Riboflavin on Protein Folding Dynamics

Animal Research and One Health, EarlyView.
Riboflavin deficiency impairs oxidative protein folding, causing ER misfolded protein accumulation, CHOP activation, and apoptosis, revealing a role of riboflavin in proteostasis. ABSTRACT Riboflavin is a crucial micronutrient essential for maintaining cellular homeostasis, acting as an important precursor for flavoproteins that utilize flavin ...

Characterization of Two VAO-Type Flavoprotein Oxidases from Myceliophthora thermophila

Molecules, 2018
The VAO flavoprotein family consists mostly of oxidoreductases harboring a covalently linked flavin cofactor. The linkage can be either monocovalent at position 8 with a histidine or tyrosine or bicovalent at position 8 with a histidine and at position 6

Myocardial inflammation is associated with impaired mitochondrial oxidative capacity in ischaemic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1246-1255, April 2025.
Abstract Aims Myocardial inflammation and impaired mitochondrial oxidative capacity are hallmarks of heart failure (HF) pathophysiology. The extent of myocardial inflammation in patients suffering from ischaemic cardiomyopathy (ICM) or dilated cardiomyopathy (DCM) and its association with mitochondrial energy metabolism are unknown.
