Some research has pointed to OPEs as potential hormone disruptors. And if OPEs are Nike Roshe Run Mujer making their way into house cats, those chemicals might be affecting humans, too.To measure if OPE flame retardants are www.ranmoorpharmacy.co.uk causing harm in our feline friends, and possibly shed light Adidas ZX Flux Dames on how the additives may affect humans, the researchers fitted house cats with pet tags Nike Air Max 90 Mujer made of silicone.The tags “mimic biological cells” by absorbing chemicals Adidas NMD Womens present in the air, said Kim Nike Roshe Run Mujer Anderson, a chemist at Oregon State University who led the study.She explained these tags measure “bioavailability” Nike Internationalist Femme — which means chemicals that enter the pet tags likely will also enter animal’s cells. Rather than just www.palmyreroigt.fr record the chemical levels in the surrounding air or environment, the pet tags report a more accurate picture of what accumulates inside of an animal — without requiring a blood or urine sample.

In a previous study on pregnant women, measurements Nike Air Max 720 Femme by silicone bracelets more accurately matched urine samples than Adidas ZX Flux Mujer measurements taken using traditional air filters in backpacks.The team fitted 78 older house cats — 39 with hyperthyroidism and 39 without — with silicone pet tags. After a week, the team extracted the adsorbed Nike Air Max Thea Mujer Nike Air Presto Dames chemicals by washing the tags in ethyl acetate. To measure the amount of OPE in each pet tag, the rinse Nike Air Max 720 Femme was injected into a machine — called a gas chromatography mass spectrometer — that identifies chemicals based Adidas Gazelle Womens on their size.To check if specific cat behaviors were associated with higher levels of OPEs, the researchers also asked pet owners to fill out a questionnaire about their household, including questions about where cats spent most of their time and when new furnishings were purchased.

All of the pet tags adsorbed Nike Air Max 270 Dames at least one type of OPE. But cats with hyperthyroidism had 16 percent higher Nike Air Max 90 Femme levels on average of one particular OPE–called Tris(1,3-dichloro-2-isopropyl) phosphate, or TDCIPP– than non-hyperthyroid cats.The higher the amount of TDCIPP found in the tags, the higher the levels of thyroid hormone found in cat Adidas Superstar Dames blood, even in those without thyroid disease.This house cat is wearing a silicone pet tag, which absorbs Nike Air Max Thea Femme chemicals from the air. When researchers analyzed one of these absorbed chemicals--a new flame www.ranchmistral.fr retardant used in Nike Air Max 1 Dames furniture and other household items--they found higher levels in cats with hyperthyroidism.
