Per- and poly-fluoroalkyl substances (PFAS) raised increasing concerns over the past years due to their persistence global distribution. Understanding occurrence in environment disruptive effect on physiology of humans wildlife remains a major challenge ecotoxicological studies. Here, we investigate several carboxylic sulfonic PFAS 105 individuals three seabird species (27 great black-backed gu...

The general population is continuously exposed to phthalates via various consumer products. Epidemiological research relating phthalate exposure thyroid function during non-developmental periods limited. This study aimed investigate the associations between specific serum metabolites and indicators of in adults. We measured 10 hormones – total triiodothyronine (TT3), free thyroxine (FT4) stimul...

Perfluoroalkyl substances (PFASs) are a group of environmentally-persistent chemicals that have been widely used in many industrial applications. There is human and animal evidence that PFASs may alter levels of reproductive and thyroid-related hormones. However, human studies on the potential age-related effects of PFASs on these outcomes among males and females are limited. We explored the re...

A cross-sectional study was performed in order to examine the association between canine aggression to familiar people and serum concentrations of total thyroxine (TT4), free thyroxine (fT4), thyroxine autoantibodies (T4AA), total triiodothyronine (TT3), free triiodothyronine (fT3), triiodothyronine autoantibodies (T3AA), thyroid stimulating hormone (TSH), and thyroglobulin autoantibodies (TgAA...

BACKGROUND Pendred syndrome (PDS) is an autosomal recessive disorder characterized by sensorineural hearing impairment and variable degree of goitrous enlargement of the thyroid gland with a partial defect in iodine organification. The thyroid function phenotype can range from normal function to overt hypothyroidism. It is caused by loss-of-function mutations in the SLC26A4 (PDS) gene. The seve...

Basal metabolic rate (BMR), the minimal energetic cost of living in endotherms, is known to be influenced by thyroid hormones (THs) which are known to stimulate in vitro oxygen consumption of tissues in birds and mammals. Several environmental contaminants may act on energy expenditure through their thyroid hormone-disrupting properties. However, the effect of contaminants on BMR is still poorl...

Mature cystic teratomas are a form of ovarian germ cell tumor and often called ‘dermoid cysts’ because they are mostly cystic. Many teratomas have teeth with morphologically identifiable crowns and roots. The objective of this study was to carry out morphometric measurements of teratomatous teeth extracted from a mature cystic teratoma excised from a 28-year-old female patient. The extracted te...

BACKGROUND During normal pregnancy, changes in thyroid function are well documented; however, information regarding thyroid function in preeclampsia is scanty. AIM The present study was planned to study thyroid hormones in mild and severe preeclamptic women and normotensive women and correlate them with outcome of pregnancy. SUBJECT AND METHODS Thyroid hormones were analyzed in mild (n = 50...
