BACKGROUND: Wedge resection is the most commonly used method in laparoscopic partial gastrectomy for gastric gastrointestinal stromal tumor (GIST). However, this method can involve inadvertent resection of additional gastric tissue and cause gastric deformation. To minimize the volume of resected gastric tissue, we have developed a laparoscopic partial gastrectomy with seromyotomy which we call the 'lift-and-cut method' for gastric GIST. Here, we report a case series of this surgery. METHOD: First, the seromuscular layer around the tumor is cut...

AIM: To assess the clinical utility of the Glasgow prognostic score (GPS) as a blood predictor of postoperative recurrence in patients with gastric gastrointestinal stromal tumors (GISTs). PATIENTS AND METHODS: Twenty-nine patients with gastric GISTs undergoing gastrectomy were retrospectively reviewed. Patients were classified based on GPS criteria as follows: GPS of 2: elevated C-reactive protein (>1.0 mg/dl) and hypoalbuminemia (<3.5 g/dl), GPS of 1: one of these hematological abnormalities, and GPS of 0: neither elevated CRP nor hypoalbuminemia...

When remembering a natural scene, both detailed information about specific objects and summary representations such as the gist of a scene are encoded. However, formal models of change detection that are used to estimate working memory capacity, typically assume observers simply encode and maintain memory representations that are treated independently from one another without considering the (hierarchical) object or scene structure. To overcome this limitation, we present a hierarchical variant of the change detection task that attempts to formalize the role of object structure, thus, allowing for richer, more graded memory representations...

PURPOSE: To exploit the intravoxel incoherent motion (IVIM) diffusion-weighted (DW) MRI when evaluating the therapeutic response of gastrointestinal stromal tumors (GIST) to Imatinib in a mouse model. MATERIALS AND METHODS: Mice with xenografts bearing cells from the GIST-T1 cell line were randomly divided into a treated group receiving Imatinib and a control group. DWMRI scans with 14 b-values (0-1500 s/mm2) were performed before and after treatment (days 1, 3 and 7)...

Imatinib (Gleevec) is a biological agent that is approved for the treatment of chronic myeloid leukemia (CML) as well as gastrointestinal stromal tumor (GIST). The most frequently seen adverse effects in patients treated with imatinib include superficial edema, muscle cramps, musculoskeletal pain, rash, fatigue, headache, abdominal pain, and joint pain. Ototoxicity has rarely been reported except in two cases. We report a case of bilateral irreversible sensorineural hearing loss (SNHL) caused by imatinib in a patient receiving this agent in the adjuvant setting...

Human immunodeficiency virus (HIV) epidemic has undoubtedly increased the incidence of tuberculosis (TB) globally, posing a formidable global health challenge affecting 1.2 million cases. Pulmonary TB assumes utmost significance in the programmatic perspective as it is readily transmissible as well as easily diagnosable. HIV complicates every aspect of pulmonary tuberculosis from diagnosis to treatment, demanding a different approach to effectively tackle both the diseases. In order to control these converging epidemics, it is important to diagnose early, initiate appropriate therapy for both infections, prevent transmission and administer preventive therapy...

The Delta-like 1 homolog (DLK1) gene is a paternal imprinting gene located on human chromosome 14q32, a site associated with frequent chromosomal mutations in GIST. The expression level of DLK1 is closely associated with the outcome of tumours. However, no study has reported the DLK1 expression in GIST. Here, we demonstrated that DLK1 showed low expression in GIST patients with low risk according to the modified National Institute of Health (NIH) criteria. With increasing tumour risk level, DLK1 gene and protein expression levels gradually increased...

: Over the course of systems consolidation, there is a switch from a reliance on detailed episodic memories to generalized schematic memories. This switch is sometimes referred to as "memory transformation." Here we demonstrate a previously unappreciated benefit of memory transformation, namely, its ability to enhance reinforcement learning in a dynamic environment. We developed a neural network that is trained to find rewards in a foraging task where reward locations are continuously changing...

While the influence of sleep on memory has a long history, sleep's role in the formation of false memories is less clear. Moreover, virtually nothing is known about the development of false memories beyond delays of about 12 hours. Here, for the first time, we assess post-sleep development of true and false memories across longer delay intervals of 24 and 48 hours. Although technically a false memory, remembering information that is related to the theme, or gist, of an experience can be considered an adaptive process...

Several structural scene cues such as gist, layout, horizontal line, openness, and depth have been shown to guide scene perception (e.g., Oliva & Torralba, 2001); Ross & Oliva, 2009). Here, to investigate whether vanishing point (VP) plays a significant role in gaze guidance, we ran two experiments. In the first one, we recorded fixations of 10 observers (six male, four female; mean age 22; SD = 0.84) freely viewing 532 images, out of which 319 had a VP (shuffled presentation; each image for 4 s). We found that the average number of fixations at a local region (80 × 80 pixels) centered at the VP is significantly higher than the average fixations at random locations (t test; n = 319; p < 0...

The present case report described the acute presentation, diagnosis and management of a primary gastrointestinal stromal tumour (GIST) of the ileum. A male patient (age, 51 years) was admitted to Maggiore Hospital (Parma, Italy) due to presenting with fever, dysuria and lower abdominal pain. Ultrasonography and computed tomography showed a 7,5×5,5-cm pelvic mass containing air and purulent fluid indicative of an intraperitoneal abscess. The patient was subjected to diagnostic laparoscopy, which revealed a huge, soft cystic mass arising from the small bowel...

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the digestive tract, and this disease has served as a paradigmatic model for successful rational development of targeted therapies. The introduction of tyrosine kinase inhibitors with activity against KIT/PDGFRA in both localized and advanced stages has remarkably improved the survival in a disease formerly deemed resistant to all systemic therapies. The Spanish Society of Medical Oncology (SEOM) guidelines provide a multidisciplinary and updated consensus for the diagnosis and treatment of GIST patients...

The angiogenic pathway plays a pivotal role in tumor growth, invasiveness and metastasis. The most important actors in the angiogenic pathway are VEGFA and its receptors VEGFR1, 2 and 3. These genes are polymorphic, and the presence of single nucleotide polymorphisms may result in angiogenic deregulation. Herein, we hypothesized that germline variants may affect sunitinib efficacy (TTP and OS) and/or toxicity. Therefore, we investigated 19 polymorphisms, in four genes, in 54 GIST patients, treated with second-line sunitinib and 147 healthy controls...

People are good at rapidly extracting the "gist" of a scene at a glance, meaning with a single fixation. It is generally presumed that this performance cannot be mediated by the same encoding that underlies tasks such as visual search, for which researchers have suggested that selective attention may be necessary to bind features from multiple preattentively computed feature maps. This has led to the suggestion that scenes might be special, perhaps utilizing an unlimited capacity channel, perhaps due to brain regions dedicated to this processing...

BACKGROUND: Genetic analysis of tissue derived from patients with advanced gastrointestinal stromal tumors (GISTs) is not uniformly applied on a national and international level, even though mutational data can provide clinically relevant prognostic and predictive information, especially in patients qualifying for treatment with expensive targeted agents. METHODS: The current article describes the rationale for genetic testing of GIST tissue, looks at financial implications associated with such analysis and speculates on potential cost savings introduced by routine mutational testing and tailored use of tyrosine kinase inhibitors based on genotyping...

Water plays a significant role in the binding process between protein and ligand. However, the thermodynamics of water molecules are often underestimated, or even ignored, in protein-ligand docking. Usually, the free energies of active-site water molecules are substantially different from those of waters in the bulk region. The binding of a ligand to a protein causes a displacement of these waters from an active site to bulk, and this displacement process substantially contributes to the free energy change of protein-ligand binding...

BACKGROUND AND OBJECTIVES: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. Previous literature has suggested that small intestine GISTs are more aggressive than gastric GISTs. Our primary objective was to compare the outcomes of gastric and small intestine GISTs in the decade after approval of imatinib for treatment. METHODS: The SEER database was queried for cases of gastric and small intestine GIST between the years 2002 and 2012, using the ICD-O-3 histology code 8936...

The present data are related to the article entitled "Insights into ligand stimulation effects on gastro-intestinal stromal tumors signaling" (C. Bahlawane, M. Schmitz, E. Letellier, K. Arumugam, N. Nicot, P.V. Nazarov, S. Haan, 2016) [1]. Constitutive and ligand-derived signaling pathways mediated by KIT and PDGFRA mutated proteins found in gastrointestinal stromal tumors (GIST) were compared. Expression of mutant proteins was induced by doxycycline in an isogenic background (Hek293 cells). Kit was identified by FACS at the cell surface and found to be quickly degraded or internalized upon SCF stimulation for both Kit Wild type and Kit mutant counterparts...

Bin Li, Kaili Cheng, Zhezhou Yu
We proposed a new method of gist feature extraction for building recognition and named the feature extracted by this method as the histogram of oriented gradient based gist (HOG-gist). The proposed method individually computes the normalized histograms of multiorientation gradients for the same image with four different scales. The traditional approach uses the Gabor filters with four angles and four different scales to extract orientation gist feature vectors from an image. Our method, in contrast, uses the normalized histogram of oriented gradient as orientation gist feature vectors of the same image...
