Salmeterol

Looking at birth records from Denmark dating between 1997 and 2007, it was determined that “This study adds to a body of recent research suggesting that medications used for certain common health conditions like asthma, when taken in pregnancy, may influence a newborn’s neurodevelopment,” Newschaffer said.

B2AR agonist drugs – which include salmetereol and formoterol – are used to relax the bronchial passages in a person’s lungs, providing a release from the constricting nature of asthma. According to the study, B2AR drugs can cross the placenta and reach the fetus, which may have an effect on its developing neurons.

Using Denmark’s Civil Registration System, Gidaya and the research team drew their sample from births in Denmark between Jan. 1, 1996 and Dec. 31 2006...

Water pollution is one of today’s most serious global problems. A new water filtration system has been developed that is superior to existing systems at removing various toxic heavy metal ions and radioactive substances from water and can even be used in gold recovery. Prof. Raffaele Mezzenga’s hybrid filter membrane not only has an extremely simple structure, but uses low-cost raw materials, such as whey protein fibres and activated charcoal...

A new Yale study shows the brain responds to taste and calorie counts in fundamentally different ways. And only one of these responses explains why most New Years’ resolutions have already disappeared under a deluge of Boston Crème Pies. It’s the brain’s desire for calories – not sweetness – that dominates our desire for sugars.

“It turns out the brain actually has two segregated sets of neurons to process sweetness and energy signals,” said Ivan de Araujo of the John B. Pierce Laboratory. “If the brain is given the choice between pleasant taste and no energy, or unpleasant taste and energy, the brain picks energy.”

Both sweet taste and nutrient value register in the striatum, an ancient region of the brain involved in processing rewards...

The onset of cardiac failure after acute myocardial infarction (AMI) is a serious problem throughout the world. Researchers at Osaka University clarified cell adhesion inhibition of periostin1 damages myocardinal cells, inducing compromised cardiac myocyte contractile force and myocytes death, leading to the onset of cardiac failure after AMI through the administration of periostin neutralizing antibodies they had developed on their own.

If the onset of cardiac failure in the chronic phase can be inhibited by this group’s research results that will not only improve patients’ quality of life, but also reduce high medical costs of cardiac failure treatment as a whole.

AMI generates me...
