BACKGROUND Single nucleotide polymorphisms (SNPs) may function as modifiers of the RET proto-oncogene, resulting in the expression of medullary thyroid carcinoma (MTC) and papillary thyroid carcinoma (PTC). We present 2 non-related Italian-American families (Family 1, n = 107; Family 2, n = 31) with the RET V804M mutation. We have correlated the presence of specific SNPs and the rare RET V804M ...

A method of performing magnetization transfer contrast (MTC) using a pulse sequence based on a series of on-resonance binomial pulses preceding a conventional spin-echo sequence has been recently described. We investigated this technique in the evaluation of circumscribed hepatic neoplasms on a 0.5 T imager. Conventional spin-echo imaging was performed in 18 patients with hepatic neoplasms, 15 ...

We evaluated a multiplex-PCR to differentiate Mycobacterium bovis from M. tuberculosis Complex (MTC) by one step amplification based on simultaneous detection of pncA 169 C > G change in M. bovis and the IS6110 present in MTC species. Our findings showed the proposed multiplex-PCR is a very useful tool for complementation in differentiating M. bovis from other cultured MTC species.

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.

Medullary thyroid carcinoma (MTC) originates from the C‑cells of the thyroid and is not sensitive to radiation or chemotherapy. Therefore, surgical removal of the tumor tissue in its entirety is the only curative treatment for MTC. The present study aimed to examine the potential mechanisms of action of extracts of Trailliaedoxa gracilis (TG; WW Smith & Forrest), a plant from the province of Si...

The therapeutic options for patients with metastatic medullary thyroid carcinoma (MTC) have recently increased due to the development of tyrosine kinase inhibitors (TKIs), some of which have achieved remarkable clinical responses in MTC patients. However, the molecular basis for the large variability in TKI responses is unknown. In this exploratory study, we investigated the expression of eight...

Medullary thyroid carcinoma (MTC) originating from the calcitoninsecreting parafollicular cells is a relatively uncommon disease. It constitutes 3% to 10% of all thyroid malignancies (1). MTC may occur in sporadic or rarely familial form as a part of multiple endocrine neoplasia syndrome type 2A and 2B. The sporadic MTC is mostly detected on the basis of clinical symptoms. Calcitonin that is se...

background :polymerase chain reaction (pcr) assay has widely used for the detection of tuberculosis (tb). this study tried to compare in-house pcr with some well-known commercial pcr kits for detection of tb agent. methods : clinical samples obtained from 620 tb suspected patients were analyzed for the diagnosis of mycobacterium tuberculosis complex (mtc) by in-house pcr. all samples were obtai...

BACKGROUND Mycobacterium tuberculosis is the principal etiologic agent of human tuberculosis (TB) and a member of the M. tuberculosis complex (MTC). Additional MTC species that cause TB in humans and other mammals include Mycobacterium africanum and Mycobacterium bovis. One result of studies interrogating recently identified MTC phylogenetic markers has been the recognition of at least two dist...

Toe speed during gait generally nears its maximum while its height reaches a local minima approximately halfway through swing phase. Trips are thought to frequently occur at these local minima (minimum toe clearance or MTC events) and trip risk has been quantified using the minimum distance between the toe and ground here (MTC). This study investigated MTC on floor surfaces with and without mul...
