BACKGROUND Primary hepatic neuroendocrine carcinomas are extremely rare. Because of the rarity of PHNEC, its clinical features and treatment outcomes are not well understood. A proper diagnosis and the correct therapeutic approach therefore remain clinically challenging. CASE PRESENTATION A 67-year-old man was admitted to our department because of a liver tumor. Computed tomography revealed a...
A case of a nine-year-old, intact female, American Bulldog with heart mass is described. Echocardiography was used to identify this pathological lesion. Part the and pericardial sac were surgically removed for histopathological examination. final diagnosis neuroendocrine carcinoma diagnosed by necropsy histopathology. To author's knowledge, there very limited information in literature about pat...
this study was intended to analyze the listening tapescripts of the elementary and pre-intermediate levels of total english textbooks from the pragmatic dimension of language functions and speech acts in order to see whether the listening tasks are pragmatically informative or not. for this purpose, 8 conversations from the two books were selected randomly, and then, the two pragmatic models of...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
BACKGROUND Small cell neuroendocrine carcinoma is very rarely encountered within the endometrium. CASE STUDY A patient underwent a hysterectomy and salpingo-oophorectomy for a suspicious gynecologic condition. Pathology revealed invasive small cell neuroendocrine carcinoma of the endometrium; the neoplasm exhibited positive immunoreactivity for synaptophysin, pancytokeratin and CD56 but was n...
we have devided the thesis in to five chapters. the first recollects facts from purely algebraic theory of jordan algebras and also basic properties of jb and jb* - algebras which are needed in the sequel. in the second chapter we extend to jb* - algebras, a classical result due to cleveland [8]. this result shows shows the weakness of jb* - norm topology on a jb* - algebera. in chapter three, ...

OBJECTIVE Rare disease. BACKGROUND Neuroendocrine carcinomas of the genitourinary tract are rare but distinct and important entities because they are very aggressive tumors and are usually advan...
126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
RATIONALE In clinical work, neuroendocrine synchronous multiplicity carcinoma was relatively rare. Most were confirmed by the pathological diagnosis of a certain part of the body combined with the imaging of the whole body, while cases that had both pathological and immunohistochemistry diagnosis were few. PATIENT CONCERNS A patient who presented with abdominal pain visited our hospital, and ...
