Background: Hypothyroidism is an important risk factor for cardiovascular diseases, and autoimmune thyroiditis (AIT) is the leading cause of hypothyroidism. Recent studies showed that even AIT patients with euthyroidism still had an increased number of early atherosclerotic lesions. However, the precise mechanism is not yet known. This study aimed to investigate the association of thyroid function, thyroid autoimmunity, and cardiometabolic risk factors in non-obese AIT patients with euthyroidism...

BACKGROUND: Oxytocin is a neuropeptide associated with maternal behavior. However the mechanisms underlying this link remain unclear. In a previous study we observed an indirect effect of increased plasma oxytocin during late pregnancy on early postpartum maternal interactive behavior via theory of mind, as assessed by the Reading the Mind in the Eyes Test (RMET). The current study aimed to extend these findings by testing whether this indirect effect would hold longitudinally for maternal behavior at 2-3 years postpartum, as well as for an additional observational measure of maternal mind-mindedness...

Selenium nanoparticles (Se-NPs) are customizable drug delivery vehicles that show good bioavailability, higher efficacy and lower toxicity than ordinary Se. Pre-treatment of male rats with these NPs has been recently shown to exert a protective effect against chromium-induced thyroid dysfunction. This study, therefore, aimed to investigate and characterize the potential protective mechanism of Se-NPs against lead (Pb) acetate-induced thyrotoxicity. We found that prophylactic and concurrent treatment of Pb acetate-exposed rats with Nano-Se (0...

Selenium (Se) is an essential trace element that is involved in numerous biological processes in the form of a selenoprotein such as iodothyronine deiodinase (DIO). Se deficiency may prevent the conversion of T4 to T3 through reducing DIO expression and thereby affecting thyroid hormone status. However, this has not been well documented in humans. In this study, to clarify the association between Se and thyroid hormone status, we investigated the thyroid hormone levels in patients with severe Se deficiency (< 2 µg/dl)...

The aim of this study was to assess the effects of neonatal bisphenol A (BPA) administration on neuroendocrine features (the thyroid-brain axis). BPA (20 or 40 µg/kg) was orally administered to juvenile male albino rats ( Rattus norvegicus) from postnatal days (PNDs) 15 to 30. Both doses resulted in lower serum thyroxine (T4), triiodothyronine (T3), and growth hormone levels and higher thyrotropin level than the control levels at PND 30. In the neonatal cerebellum and cerebrum, vacuolation, pyknosis, edema, degenerative changes, and reductions in the size and number of the cells were observed in both treated groups...

The physiological activity of the steroid derived hormone vitamin D is regulated by several enzymatic steps. Both 25-hydroxy vitamin D3 1α-hydroxylase (CYP27B1) and 25-hydroxyvitamin D3 24-hydroxylase (CYP24A1) modulate blood levels of 1,25-dihydroxyvitamin D3 , an activated form of vitamin D. We previously demonstrated that CYP27B1 expression was trans-activated by sterol regulatory element binding protein 1 (SREBP1), although whether SREBP1 also regulates CYP24A1 transcription was unclear. Here we investigated the ability of SREBP1 to affect CYP24A1 transcription...

BACKGROUND: Ripening of cheddar cheese is a time taking process, duration of the ripening may be as long as one year. Long ripening time is a big hindrance in the popularity of cheese in developing countries. Further, energy resources in these countries are either insufficient or very expensive. Therefore, those methods of cheese ripening should be discovered which can significantly reduce the ripening time without compromising the quality characteristics of cheddar cheese. In accelerated ripening, cheese is usually ripened at higher temperature than traditional ripening temperatures...

AIM: One-lung ventilation (OLV) is an anesthesia technique used to provide visualization in thoracoscopic lung surgeries and increase surgical site visibility during operation. In OLV, atelectasis occurs and blood from the lung participates in circulation without receiving oxygen. We designed a prospective study on patients we implemented surgery in order to research whether OLV leads to oxidative stress and DNA damage or not. METHODS: It was taken 5cc blood samples 4 times from these patients in the postoperative preparatory stage (T1), on the 60th minute after the start of OLV (T2), on the 60th minute after the termination of OLV (T3) and 24 hours after surgery (T4)...

Radiotherapy (RT) is applied in prostate cancer patients with a biochemical recurrence (BcR) after radical prostatectomy (RP). However, for the patients with persistent PSA but not undergoing the process of BcR, it remains unknown whether the application of RT can exempt them from the upcoming BcR. In this study, we identified 104 patients treated with RP who had persistent PSA level >0.1 but ≤0.2 ng/mL at 6-8 weeks after RP, of which 52 were treated with postoperative RT. Overall, 51 patients experienced BcR, among which 20 patients were treated with postoperative RT...
