Mutational processes and signatures that drive early tumorigenesis are centrally important for early cancer prevention. Yet, to date, biomarkers and risk factors for polyps (adenomas) that inordinately and rapidly develop into colon cancer remain poorly defined. Here, we describe surprisingly high mutational profiles through whole-genome sequence (WGS) analysis in 2 of 4 pairs of benign colorec...
Primary hyperparathyroidism is a quite frequent disorder however, giant parathyroid adenoma is a rare entity. We described a 39-year old woman presenting with lower extremities bone pain within the recent 3 years. She had been receiving levothyroxin during the past 10 years due to hypothyroidism, meanwhile, she had a bulge right thyroid lobe. Laboratory examinations revealed she was euthyroid, ...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
Three dogs were evaluated due to the presence of unilateral adrenal gland masses with or without clinical signs. Case 1 showed a unilateral non-functional adrenocortical adenoma, discovered accidentally while Case 2 presented a unilateral cortisol-secreting adrenocortical adenoma; a pheochromocytoma was accidentally discovered in Case 3. The adrenalectomy was the treatment of choice in all case...
Introduction: Pleomorphic adenoma is a rare benign salivary gland neoplasm in children, which can be treated by simple excision. This tumor is rarely included in the differential diagnosis of solid submandibular masses in children. In the neonates, congenital pleomorphic adenoma usually presents in the nasopharynx. Surgical excision is the treatment of choice and recurrence is not expected. We ...
The epigenetic changes in pituitary adenomas were identified by evaluating the methylation status of nine genes (RB1, p14ARF, p16INK4a, p73, TIMP-3, MGMT, DAPK, THBS1 and caspase-8) in a series of 35 tumours using methylationspecific PCR analysis plus sequencing. The series included non-functional adenomas (n=23), prolactinomas (n=6), prolactinoma plus thyroid-stimulating hormone adenoma (n=1),...
abstract background: primary hyperparathyroidism is autonomous production of parathyroid hormone. after removal of adenoma, one of the surgeons concern is postoperative hypocalcaemia. there is no precise method to determine if patients have hypocalcaemia postoperatively. the purpose of this study was to determine the relation between parathyroid adenoma weights, postoperative serum calcium and ...
Although the colorectal adenoma-to-carcinoma sequence represents a classical cancer progression model, the evolution of the mutational landscape underlying this model is not fully understood. In this study, we analyzed eight synchronous pairs of colorectal high-grade adenomas and carcinomas, four microsatellite-unstable (MSU) and four-stable (MSS) pairs, using whole-exome sequencing. In the MSU...
Introduction: The purpose of this study is to assess the integrated role of scintigraphy by Tc99m MIBI in diagnosis of parathyroid adenoma and its impacts on the myocardium, and to evaluate whether myocardium perfusion gated SPECT study could be a complementary routine workup for patient with positive parathyroid adenoma on Tc99m MIBI parathyroid scan. Methods: Rest myocardium perfusion gated ...
This study was to discuss the surgical diagnosis and treatment experience of primary hyperparathyroidism. Clinical data of 19 primary hyperparathyroidism patients who were treated surgically in our department from Jan. 2005 to Jul. 2014 were retrospectively analyzed. Besides, general data, clinical manifestations, laboratory and imaging test results, surgical procedures and postoperative follow...
