OBJECTIVE Risk factors for differentiated thyroid carcinoma (DTC) are poorly understood, but serum TSH levels, thyroid nodularity, and presence of autoimmunity are well-recognized factors that modulate DTC prevalence. TSH stimulates proliferation of both normal and neoplastic follicular cells. Consequently, thyroid-stimulating immunoglobulins (TSI), because of its TSH-like action, should induce...

BACKGROUND We evaluated both estrogen receptor (ER) and human epidermal growth factor receptor 2 (HER2) status on disseminated tumor cells (DTCs) in the bone marrow of 54 patients with early breast cancer and compared these with the corresponding primary tumor (PT). MATERIALS AND METHODS Bone marrow aspirates were obtained at the time of first surgery, and ER and HER2 status on DTCs was asses...

This paper presents a direct flux and torque control (DTC) of three phase induction motor drive (IMD) using PI and fuzzy logic controllers (FLC) for speed regulator (SR) and low torque ripples. This control method is based on DTC operating principles. The DTC is one of the most excellent direct control strategies of stator flux and torque ripples of IMD. The key issue of the DTC is the strategy...

در این مقاله برای تخمین وضعیت روتور در درایو موتور بدون سنسور bldc از روش نسبت توابع شار خط به خط، استفاده شده است. این روش، نسبت به سایر روش­هایی که برای تخمین موقعیت روتور مورد ارزیابی قرار می­گیرند، حجم نرم­افزار و سخت­افزار کمی داشته و لذا پیاده سازی آن آسان و هزینه ساخت نیز کمتر است. همچنین این روش در بازه وسیعی از سرعت کارایی مناسبی دارد و تخمین وضعیت روتور مستقل از سرعت و فرکانس روتور می...

Cytochrome P450 1A1 (CYP1A1) is a phase I enzyme that regulates the metabolism of environmental carcinogens and alter the susceptibility to various cancers. Many studies have investigated the association between the CYP1A1 MspI and Ile462Val polymorphisms and digestive tract cancer (DTC) risk in different groups of populations, but their results were inconsistent. The PubMed and Embase Database...

Direct torque control (DTC) of induction motors (IMs) requires an accurate knowledge on the amplitude and angular position of the controlled flux in addition to the information related to angular velocity for velocity control applications. However, unknown load torque and uncertainties related to stator/rotor resistances due to operating conditions constitute major challenges for the performanc...

OBJECTIVE To determine the association between glutathione S-transferase (GST) polymorphisms and the risk of differentiated thyroid carcinoma (DTC) and benign thyroid tumors. DESIGN Case-control study. SETTING Tertiary care cancer center. PATIENTS Two hundred one patients with DTC, 103 patients with benign thyroid tumors, and 680 cancer-free control subjects. MAIN OUTCOME MEASURES Resul...

objective(s): in clinical practice, approximately 10-25% of post-surgical differentiated thyroid carcinoma (dtc) patients with high serum thyroglobulin (tg) and negative 131i whole-body scan (wbs) have poor prognosis due to recurrent or metastatic lesions after radioactive iodine treatment. the purpose of this study was to evaluate the value of 18f-fdg pet/ct scan in dtc patients with high seru...
