This study found that intermediate-term oral contraceptive use was associated with lower antioxidant levels and higher triglyceride and low-density lipoprotein levels. Regular monitoring of these parameters is recommended for OCP users to mitigate potential metabolic and hepatic effects.
This study investigates the role of GPX4 methylation in ferroptosis during hepatic ischemia-reperfusion injury. Ferroptosis is observed in oxygen and glucose deprivation, characterized by decreased cellular viability and increased lipid peroxidation.
A new study found that subclinical hypothyroidism diagnosed before 21 weeks of pregnancy is associated with higher rates of overt hypothyroidism or thyroid replacement therapy within 5 years after delivery. Women with high TSH values and elevated TPO antibodies were at increased risk.
Researchers from Osaka University have developed a bioprinting technique that enables the creation of complex soft tissue structures with high fidelity. The method uses a printing support to facilitate gelation of a bioink, resulting in cell viability and viability for up to two weeks.
Scientists develop a strategy to synthesize biomolecule-metalorganic frameworks with high bioactivity by adding peptides as modulators. These biohybrids can mimic cellular cascades and function as optical glucose sensors, offering potential for industrial applications.
A KAIST research team synthesized a peroxidase-mimicking nanozyme with superior catalytic activity and selectivity, overcoming the limitations of natural enzymes. The nanozymes can accurately detect target materials like hydrogen peroxide and acetylcholine, paving the way for early diagnosis of Alzheimer's disease.
A new catalyst developed by Michigan Technological University researchers has improved the sensitivity of the PSA test for prostate cancer detection. The palladium-iridium catalyst is 110 times more sensitive than traditional peroxidase-based tests, reducing false negatives and potentially delaying treatment.
Researchers at the University of Leicester have discovered a potential molecular defence against Huntington's disease, a fatal neurodegenerative disorder. Glutathione peroxidase activity was found to be robustly protective in models of the disease.
Researchers from MIT have developed a new tag, APEX, that enables high-resolution visualization of proteins in cells using electron microscopy. The APEX tag allows scientists to label and identify specific proteins with unprecedented clarity, resolving open questions regarding protein locations and functions.
