PondNet – towards a global network of experiments on the effects of climate change on aquatic ecosystems

Ecography, EarlyView.
Global change is reshaping the distribution of biodiversity and the functioning of ecosystems. Predicting the long‐term consequences of such changes remains a challenge due to a need for a clear understanding of the mechanisms underpinning ecosystem‐level responses, as well as the role of geographical and environmental contingencies.

Isolated cytochrome c oxidase deficiency as a cause of MELAS

BMJ Case Reports, 2008
Deletion of a single nucleotide (7630delT) within MT-CO2, the gene of subunit II of cytochrome c oxidase (COX), was identified in a clinically typical MELAS case. The deletion-induced frameshift results in a stop codon close to the 5′ end of the reading frame.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues

ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.
Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

Lymphopoiesis is attenuated upon hepatocyte-specific deletion of the cytochrome c oxidase assembly factor Sco1

iScience
Summary: Mutations that negatively impact mitochondrial function are highly prevalent in humans and lead to disorders with a wide spectrum of disease phenotypes, including deficiencies in immune cell development and/or function. Previous analyses of mice

A New Vista of Opportunity in Diabetes Management: Natural Product‐Based β‐cell Preservation

Food Chemistry International, EarlyView.
Preserving functional β‐cells via natural products offers promising strategy for diabetes treatment. ABSTRACT A defining characteristic of diabetes is β‐cell failure, in which β‐cells cannot modulate insulin secretion to compensate for escalating insulin resistance, pushing forward disease development.

Immunomodulatory and Cytotoxic Properties of Enniatin B1 in Porcine Alveolar Macrophages

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study investigates the immunomodulatory effects of Enniatin B1 (ENNB1), an emerging mycotoxin, on porcine alveolar macrophages (PAMs), a species‐specific model relevant to human innate immunity. PAMs were exposed to increasing ENNB1 concentrations (0.5–6 μM) over 6, 24, and 48 h.
