Nanodiamond Quantum Sensors for Probing Free Radical Biology

Advanced Functional Materials, Volume 36, Issue 45, 5 June 2026.
Free radicals play key roles in cellular signaling and disease but remain difficult to measure in living systems. Nanodiamonds (NDs) with nitrogen‐vacancy (NV) centers enable quantum sensing of local magnetic noise via T₁ relaxometry, providing nondestructive radical detection in living cells.

Targeting Myostatin for Sustainable Meat Production: Insights From Multiple Species

Animal Genetics, Volume 57, Issue 3, June 2026.
ABSTRACT Myostatin gene (MSTN), a TGF‐β superfamily member, negatively regulates skeletal muscle growth, positioning it as a prime genetic target for enhancing livestock meat production. This review synthesizes evidence from 1979 to 2025 on MSTN mutations across cattle, pigs, poultry, sheep, goats, and rabbits, emphasising impacts on yield, quality ...

Effect of heparin on in vitro capacitation of boar sperm [PDF]

Biological Research, 2006
Chlortetracycline (CTC) fluorescent pattern, the ability to undergo acrosome reaction (AR) upon exposure to 10 microM calcium ionophore A23187 and vitality estimation were used to investigate the effect of the sulfated glycosaminoglycan heparin on the in vitro capacitation of porcine spermatozoa.

GGAs: Regulation of Multiple Sorting Pathways and Potential Association With Human Diseases

Journal of Cellular and Molecular Medicine, Volume 30, Issue 11, June 2026.
ABSTRACT Golgi‐localized gamma‐ear‐containing Arf‐binding proteins (GGAs) are a family of monomeric clathrin adaptors that function in intracellular vesicle trafficking. The three GGA family members—GGA1, GGA2 and GGA3—were first identified as sorting adaptors almost simultaneously by independent research groups in 2000. It is now well established that

Role of oxidative stress and antioxidants in domestic and non-domestic cat spermatozoa [PDF]

, 2010
Living cells, including spermatozoa, stored under aerobic conditions require oxygen to support their normal metabolism. Excessive levels of metabolites (reactive oxygen species; ROS) can cause cell damage or lipid peroxidation.

Quantification of the emetic toxin cereulide in food products by liquid chromatography-mass spectrometry using synthetic cereulide as a standard

, 2010
Bacillus cereus produces the emetic toxin cereulide, a cyclic dodecadepsipeptide that can act as a K+ ionophore, dissipating the transmembrane potential in mitochondria of eukaryotic cells.

Update of the risk assessment on dioxins and dioxin‐like PCBs in feed and food

EFSA Journal, Volume 24, Issue 6, June 2026.
Abstract The European Commission asked EFSA to update its 2018 risk assessment on polychlorinated dibenzo‐p‐dioxins and dibenzofurans (PCDD/Fs) and dioxin‐like polychlorinated biphenyls (DL‐PCBs) in feed and food, based on the 2022 WHO Toxic Equivalency Factors (WHO2022‐TEFs).
