A German study found exposure to house dust endotoxin is associated with lower allergic sensitization in school children. Researchers also discovered that females are more sensitive to coughing agents than males. Occupational exposure to dust and fumes is linked to increased respiratory symptoms and asthma risk.
A new DNA typing method has been developed to help identify human remains that cannot be matched with the current protocol. The technique, called a 'miniplex,' uses a smaller set of reliable DNA markers to study tiny pieces of genetic material and could aid law enforcement in solving cases across the country.
Researchers from Penn State College of Medicine developed a new measurement technique to assess norepinephrine release in tissues adjacent to blood vessels. This improvement allows for more accurate data on the hormone's role in vasoconstriction and maintains adequate blood pressure when standing up.
Researchers found that expectant fathers' hormones fluctuate during pregnancy, mimicking their partners' changes. Testosterone levels dropped significantly after birth, and lower levels were associated with increased paternal behavior.
Researchers at Idaho National Laboratory and Miragen are developing a technique that uses antibodies to identify individuals, offering a potential alternative to DNA testing. The Antibody Profile Assay can distinguish between identical twins and provide results in just two hours.
Cornell University scientists have developed a new technique for accurately characterizing biomolecules using electrospray mass spectrometry. This breakthrough allows researchers to analyze samples as small as a single cell with unusually high confidence, opening up new avenues for molecular investigations into human medical disorders.
