Research finds gallium nitride is non-toxic, biocompatible - holds promise for implants

Researchers at North Carolina State University and Purdue University have shown that gallium nitride (GaN) is non-toxic and biocompatible, making it a promising material for biomedical implants. The material was found to be stable in environments mimicking the human body and bonded effectively with cells when coated with peptides.

High fizzy soft drink consumption linked to violence among teens

Research published in Injury Prevention found that teens who consume high amounts of carbonated non-diet soft drinks are more likely to exhibit aggressive behavior. The study, which analyzed data from over 1,800 Boston teenagers, discovered a significant association between heavy soft drink consumption and violence perpetration.

Potential new cause of miscarriage and habitual abortion

A team of researchers has identified a non-classical form of Fetal and Neonatal Immune Thrombocytopenia (FNIT) that causes excessive platelet activation and blood clot formation in the placenta, leading to miscarriage. The condition can be prevented with intravenous IgG and anti-FcRn therapies.

British study may improve glaucoma assessment and treatment

A recent British study published in Investigative Ophthalmology & Visual Science may revolutionize the way healthcare professionals assess glaucoma risk. The study used a new method to measure intraocular pressure, correcting for corneal biomechanics, and found accurate measurements of eye pressure with improved accuracy.

Researchers have identified a non-classical form of fetal immune thrombocytopenia that can lead to miscarriage and habitual abortion. The condition is characterized by excessive platelet activation and blood clot formation in the placenta. New treatments targeting this condition have been suggested, offering hope for women affected by it.

Exposure to chemical BPA before birth linked to behavioral, emotional difficulties in girls

Exposure to BPA in the womb is associated with behavior and emotional problems in young girls, according to a Harvard T.H. Chan School of Public Health study. Higher gestational BPA concentrations were linked to more hyperactive, aggressive, anxious, and depressed behavior in girls, while boys showed no significant association.

Clues revealed to cause of deadly kidney disease in newborns

Researchers found that small vesicles called exosome-like vesicles (ELVs) are involved in transporting signals through urine and interacting with primary cilia in the kidneys. This discovery may help understand how gene mutations cause autosomal recessive polycystic kidney disease (ARPKD), a condition that often leads to kidney failure.

Foley catheter as successful as widely used hormone-like gel for inducing labor but with fewer side effects

A new trial suggests that a Foley catheter is as successful in inducing labor as the widely used hormone-like gel prostaglandin E2, but with lower rates of infection and complications. The study found similar vaginal delivery rates and reduced risks of caesarean section, operative deliveries for fetal distress, and neonatal admissions.
