مقدمه و هدف: ms یکی از شایعترین اختلالات عصبی ناتوان کننده می باشد. تشخیص پلاک فعال جدید ms در تعیین شروع حمله و بررسی وضعیت کلینیکی و شروع سریعتر درمان و ارزیابی پاسخ به درمان بسیار مهم است و mri با کنتراست بهترین اندیکاتور در این زمینه است. هدف از این مطالعه بررسی ارزش mtc بدون تزریق در تشخیص پلاکهای فعال ms است. روش کار: این مطالعه از نوع مقطعی است و بر روی 62 بیمار که دارایms شناخته شده بو...
زمینه و هدف: سرطان مدولاری تیرویید (mtc) به دو شکل اسپورادیک (75%) موارد و ارثی (25%) بروز می کند. اثر جهش های بد معنی پروتوآنکوژن ret در پیشرفت بیماری به خوبی مشخص شده است. هدف از انجام این مطالعه بررسی هاپلوتایپ g691s/s904s در بیماران mtc و خانواده آنها بود. روش بررسی: مطالعه حاضر در طی سال های 1393-1383 در مرکز تحقیقات سلولی و مولکولی پژوهشکده غدد درون ریز و متابولیسم دانشگاه علوم پزشکی شهید...
the coexistence of medullary thyroid carcinoma (mtc), papillary thyroid carcinoma (ptc) and parathyroid adenoma is an uncommon clinical entity. here, we report a case of mtc, ptc, and parathyroid adenoma diagnosed incidentally on a routine physical examination of the neck for the work-up of diabetes. the patient had neither symptoms of hypercalcemia nor those related to mtc and ptc.
approximately 5-10% of all thyroid cancers are medullary thyroid carcinomas (mtc). mtc is mainly sporadic in nature, but 20-30% of cases are hereditary. genetic testing for hereditary mtc is very important for the patient and his family, but the patients must be receiving appropriate genetic counseling. about 98% of patients with hereditary mtc have germline mutations in exons 10, 11, 13, 14, 1...
meduiiary thyroid carcinoma (mtc) occurs both sporadically and in the autosomal dominantly inherited multiple endocrine neoplasia (men) type 2 syndromes. the distinction between true sporadic mtc and a new mutation familial case is important for future clinical management of both the patient and family. the susceptibility gene for hereditary mtc is the ret proto-oncogene. dna analysis for germl...
medullary thyroid carcinoma (mtc) occurs in both sporadic (75%) and hereditary (25%) forms. the missense mutations of the rearranged during transfection (ret) proto-oncogene in mtc development have been well demonstrated. the aim of this study was to investigate frequency of g691s/s904s haplotype in mtc patients and their relatives.in this research 293 participants were studied, including 181 p...
Introduction: Medullary thyroid cancer (MTC) is an uncommon neoplasm originating from parafollicular C cells. Distant metastasis in MTC, such as axillary node involvement, is extremely rare. Case Report: The present study describes a known case of MTC with axillary lymph node metastasis in a 31-year-old woman. In 2010, she underwent total thyroidectomy and right-sided modified radical neck dis...
Medullary thyroid carcinoma (MTC) is a neuroendocrine cancer that originates from calcitonin-secreting parafollicular cells, or C cells. We found that Cdk5 and its cofactors p35 and p25 are highly expressed in human MTC and that Cdk5 activity promotes MTC proliferation. A conditional MTC mouse model was generated and corroborated the role of aberrant Cdk5 activation in MTC. C cell-specific over...
BACKGROUND Poor prognosis of medullary thyroid cancer (MTC) with suspicious ultrasound (US) features has been reported. The aim of the study was to investigate the association between preoperative US presentation and aggressiveness features of MTC. Also, US features of MTC were compared with those previously reported. METHODS Study group comprised 134 MTC from nine different centers. Based on...
Machine type communications (MTCs) enable the communications of machines (devices) to machines over mobile networks. Besides simplifying our daily lives, the MTC business represents a promising market for mobile operators to increase their revenues. However, before a complete deployment of MTC over mobile networks, there is need to update the specifications of mobile networks in order to cope w...
