The objectives of the present study were to investigate the prevalence of histologic thyroids lesions and the respective thyroid hormones changes of ewes in an endemic goiter region and to find out any impact of this condition on the fetal thyroid structures and serum thyroid hormones. In the present study a total number of 100 pregnant ewes and their fetuses slaughtered at slaughterhouse were...

  Radioiodine (1-131) is the treatment of choice in differentiated thyroid carcinoma. External radiotlierapy however, has it's own roie in these tumors. Treatment of anaplastic thyroid carcinoma 1ms not acliieved any notahle success yet, though combined - modality regimens of radiotherapy and chemotherapy have sometimes shown significant results. In this paper the rol...

Background  It is remain a main concern that pediatric chest radiographies contribute to the significant radiation exposure to the thyroid gland as a more susceptible organ to radiation induced cancer. The aim of this study was to evaluate the entrance surface dose (ESD) of pediatric chest radiography compared to the diagnostic reference levels (DRL) and evaluation the efficacy of the lead (Pb)...

abstract background and aim: survivin is a new member of inhibitor of apoptosis protein family (iap) that plays an important role in the regulation of cell cycle and inhibition of apoptosis. distinct expression of this gene in tumoral cells versus normal cells introduces it as the fourth major transcriptome in cancers. thyroid carcinoma is the most common endocrine malignancy. considering the h...

introduction struma ovarii is an ovarian teratoma, represented in more than 50% by thyroid tissue. five percent of struma ovarii cases have been proven to be malignant and, as in the thyroid gland, papillary thyroid carcinoma is the most common histotype arising in struma ovarii. because of the unusual occurrence of this tumor, its management and follow-up after pelvic surgery is still controve...

caraway is one of the medicinal plants used for digestion problems, however, it has been reported that the long term use of this plant in large doses might cause hyperthyroidism symptoms such as leanness, hair loss, severe sweating and tremulousness. therefore, the aim of this study was to evaluate the effect of hydroalcoholic extract of caraway on the level of thyroid hormones and morphologic ...

normal 0 false false false en-us x-none ar-sa anaplastic thyroid cancer (atc) is a rare disease with an incidence of less than three cases per million of habitants in western countries. atc accounts for 1‑10% of all tumors derived from the thyroid gland. classic chemotherapy approach based on platinum and anthracyclines regimens have been considered standard for the last decades. novel multit...

Polycyclic aromatic hydrocarbons (PAHs) are contaminants of interest due to their known toxic effects. PAHs may interfere with physiological and biochemical activities soil organisms like Lumbricus terrestris. metabolites have been employed in the assessment external exposure metabolic activation. Thus, this study investigates antioxidant stress markers terrestris which is a recognized bioindic...

Background: Within the context of developing techniques to facilitate the diagnosis of the thyroid diseases, the elemental composition of pathological thyroid tissue (neoplastic and non-neoplastic) was investigated by proton induced X-ray emission. The PIXE has been widely used as a sensitive technique for trace elemental analysis in both biological and medical fields. Materials and Methods: Th...
