Gastrointestinal stromal tumor (GIST), a form of soft-tissue sarcoma, is the most common noncarcinomatous tumor of the gastrointestinal tract. Despite its high incidence of recurrence, the malignant potential of GIST has been under-recognized. Advances in diagnostic technology since 2000 have led to increased diagnoses of GIST, suggesting that GIST is more common than previously suspected. Hist...
Alzheimer's disease (AD) reduces associative effects on false recognition in the Deese-Roediger-McDermott task, either due to impaired memory for gist or impaired use of gist in memory decisions. Gist processes were manipulated by blocking or mixing studied words according to their associations and by varying the associative strength between studied and nonstudied words at test. Both associativ...
This document describes state machines for the General Internet Signaling Transport (GIST). The states of GIST nodes for a given flow and their transitions are presented in order to illustrate how GIST may be implemented.
Gastrointestinal stromal tumors (GIST) occur primarily in the wall of the intestine and are characterized by activating mutations in the receptor tyrosine kinases genes KIT or PDGFRA. The diagnosis of GIST relies heavily on the demonstration of KIT/CD117 protein expression by immunohistochemistry. However, KIT expression is absent in approximately 4% to 15% of GIST and this can complicate the d...
RATIONALE Gastrointestinal stromal tumor (GIST) is the neoplasm of gastrointestinal tract. PATIENT CONCERNS The patient complained about the retention of urinary. DIAGNOSES GIST. INTERVENTIONS radical prostatectomy and the imatinib therapy. OUTCOMES No recurrence and metastasis have been found during a 14-month follow-up. LESSONS comprehensive treatment is necessary for the GIST treat...
Although the stomach is the most common location for gastrointestinal stromal tumor (GIST) with co-primary tumors, the synchronous appearance of a poorly differentiated neuroendocrine carcinoma (NEC) and GIST in the stomach is extremely rare. To the best of our knowledge, this is the first case of gastric GIST coexisting with gastric NEC to be reported in the literature. The current study repor...
Background Gastrointestinal stromal tumors (GIST) are the most common primary mesenchymal tumors of the digestive system. The assessment of their biological behavior still remains a scientific challenge. To date, there are no well-established biological prognostic markers of GIST. Our aim is to study the expression of the MDM2 oncoprotein in GIST through an immunohistochemical analysis. Metho...
Numerous studies have shown that the gist in photorealistic pictures of scenes is extracted after very short presentation times. So far, the investigation of gist extraction has been limited to pictures of scenes. The present study investigated whether the gist in pictures of causal systems, which are typically used as instructional material, is extracted as fast as the gist in pictures of scen...
Sleep benefits the consolidation of individual episodic memories. In the long run, however, it may be more efficient to retain the abstract gist of single, related memories, which can be generalized to similar instances in the future. While episodic memory is enhanced after one night of sleep, effective gist abstraction is thought to require multiple nights. We tested this hypothesis using a vi...
The aim of this study was to review the clinicopathological characteristics and survival outcomes of patients with concurrent gastrointestinal stromal tumor (GIST) and digestive tract carcinoma. Among 585 patients diagnosed with GIST from January 2005 to July 2014, 32 (5.5%) had synchronous digestive tract carcinoma, including 19 (59.4%) men and 13 (40.6%) women. The median age was 64 years (ra...
