Mbnm Question marks: Three bodies found in Swabi
When fish ingest microplastics, they often also ingest progesterone. This compound is subsequently released into the digestive tract through chemical reactions with the fish鈥檚 digestive fluids. That鈥檚 the key finding of a study carried out jointly by scientists from EPFL, the Swiss Federal Institute of Aquatic Science and Technology (Eawag), Peking University in Beijing, and Oklahoma State University, and appearing in Environmental Science: Processes & Impacts.鈥淥ur study shows that microplastics are an additional vector for exposing fish to micropollutants like progesterone, a steroid hormone that can be found in the environment,鈥?says Florian Breider, the head nike jordan4 of EPFL鈥檚 Cen air force schwarz tral Environmental Laboratory and a co-author of the study. 鈥淭hese microplastics act like sponges and serve as a vector 鈥?they readily absorb hydrophobic micropollutants in water, since the pollutants鈥?molecules would rather attach nike dunk high to the plastic,鈥?says Breider. 鈥淥nce inside a fish, the molecules are released in PARIS:Most off-label use of antidepressants is not backed by evidence that the drugs will work as intended, scientists said on Wednesday.Many medications approved for the treatment of depression are prescribed by doctors for other problems such as pain, insomnia or migraine headaches. But only a small fraction of such "off-label" treatmen stanleycup ts have been tested for efficacy and side-effects, resear new balance 996 chers reported in the medical journal BMJ.Giving adult medication to children, or in doses different from those tested in clinical trials and specified by drug-makers, are also considered off-label uses. The study found that about a third of antidepressants are prescribed for conditions other than depression.Step counting apps may do more harm than good, scientist warns"This is probably the tip of the iceberg," said lead author Jenna Wong, a resea adidas samba homme rcher at McGill University in Montreal, Canada. "There is a lot of off-label use going on, but we don't have good ways of tracking it," especially when
