Gastrointestinal stromal tumor is rare digestive tract mesenchymal tumor, most often in the wall of the stomach. It is a benign neoplasm, but it can become malignant if not treated. We report a case of gastrointestinal stromal tumor that was discovered after abdominal ultrasonography during staging of a patient with primary cutaneous amelanotic melanoma. Mutation in the tyrosine kinase receptor could explain the development of two types of tumors in the same patient.

BACKGROUND: Preterm infants' meals typically progress to higher volumes over time. Knowledge of gastric emptying (GE) responses to differing meal volumes may inform enteral feeding management. We examined the effect of meal volume and composition on preterm GE. METHODS: Forty infants were studied at 33.3±1.4 (29.7-35.6) weeks postmenstrual age when fully enteral fed (target 150 ml/kg/day). Intra-individual comparisons of GE were made for paired meals of 100 and 75% prescribed volume and identical composition of mother's own milk (n=21) and pasteurized donor human milk (n=19)...

A 62-year-old man with recently diagnosed prostatic adenocarcinoma was referred for a whole-body Ga-prostate-specific membrane antigen (PSMA) PET/CT scan for staging. Although the scan did not reveal metastatic disease, it did reveal a PSMA-avid lesion in the upper abdomen located between the liver and the stomach. Histopathologic examination demonstrated a gastrointestinal stromal tumor. The lesion demonstrated increased uptake in the margins of the tumor with a central photopenic area, which we consider to be the typical pattern on PSMA images of a gastrointestinal stromal tumor, based on theoretical PSMA distribution in such a tumor and other reported cases...

Customer demand for convenient food products has led to an increased production of prepackaged and ready-to-eat food products. Most of these products rely mainly on surface disinfection and other traditional approaches to ensure shelf life and safety. Novel processing techniques, such as cold plasma, are currently being investigated to enhance the safety and shelf life of prepacked foods. The purpose of this study was to determine the effects of cold plasma corona discharge on the inactivation of Salmonella on prepackaged, tomato-and-lettuce mixed salads...

This study was conducted to compare the effects of juice and seeds on gastric emptying, small-bowel motility and intestinal ion transport. Separate groups of rats were randomized to receive NaCl, increasing doses of juice (5, 10, and 20 mL/kg, b.w.) or seeds aqueous extract (100, 200, and 400 mg/kg, b.w.). Simultaneously, two other groups were received, the reference drugs; clonidine (1 mg/kg) and yohimbine (2 mg/kg). The charcoal meal was used as a suspension for gastrointestinal motility test. The purgative action of juice was confirmed using the loperamide (5 mg/kg, p...

OBJECTIVE: Malformations of the lymphatic system are recognized as benign congenital tumors that affect infant and children in the perinatal era. In children, these abnormalities usually found in the neck and the axillary region, but they can present in other parts of the body such as mediastinum, pelvis, retroperitoneum as well as in solid organs (e.g., adrenal glands, pancreas, stomach). Our aim is to report our experience on cystic hygromas via two cases and review the literature. MATERIALS AND METHODS: Herein we present two cases of cystic hygroma, the first of female children and the second of a female adult patient respectively...

The Roux-en-Y gastric bypass is one of the most common procedures currently performed for surgical treatment of patients with severe obesity. Gastric cancer after bariatric surgery is not common, with most of them arising in the excluded stomach. Gastric mixed adenoneuroendocrine carcinomas are a rare type of stomach malignancy, composed of both adenocarcinoma and neuroendocrine tumor-cell components, with the latter comprising at least 30% of the whole neoplasm. In this article, we report a unique case of a mixed adenoneuroendocrine carcinoma with a mixed adenocarcinoma (tubular and poorly cohesive) component arising in the gastric pouch of a patient who underwent previous Roux-en-Y gastric bypass for glycemic control...

The mouse bitter taste receptors Tas2r143, Tas2r135, and Tas2r126 are encoded by genes that cluster on chromosome 6 and have been suggested to be expressed under common regulatory elements. Previous studies indicated that the Tas2r143/Tas2r135/Tas2r126 cluster is expressed in the heart, but other organs had not been systematically analyzed. In order to investigate the expression of this bitter taste receptor gene cluster in non-gustatory tissues, we generated a BAC (bacterial artificial chromosome) based transgenic mouse line, expressing CreERT2 under the control of the Tas2r143 promoter...

Ketorolac is a powerful non-steroidal anti-inflammatory drug (NSAID), with a great analgesic activity, present on the Italian market since 1991. Despite the excellent therapeutic activity, the chronic use of ketorolac has long been limited owing to the high incidence of gastrointestinal and kidney side events. In our previous study, we demonstrated that ketorolac-galactose conjugate (ketogal), synthesized and tested in a single-dose study, was able to reduce ulcerogenicity, while preserving the high pharmacological efficacy of its parent drug...

Apex predators play a key role in ecosystem stability across environments but their numbers in general are decreasing. By contrast, European catfish (Silurus glanis), the European freshwater apex predator, is on the increase. However, studies concerning apex predators in freshwaters are scarce in comparison to those in terrestrial and marine ecosystems. The present study combines stomach content and stable isotope analyses with diet preferences of catfish to reveal its impact on the ecosystem since stocking...

Superior mesenteric artery (SMA) syndrome is one of the rare causes of small bowel obstruction. It develops following a marked decrease in the angle between SMA and the abdominal aorta due to weight loss, anatomical anomalies, or following surgeries. Nutcracker syndrome in the left renal vein may also occur following a decrease in the aortomesenteric angle. Though SMA syndrome and renal nutcracker syndrome share the same pathogenesis, concurrent development has rarely been reported. Herein, we report a 23-year-old healthy male diagnosed with SMA syndrome and renal nutcracker syndrome due to severe weight reduction...

Habitat is of great importance in determining the trophic transfer of pollutants in freshwater ecosystems; however, the major factors influencing chemical trophodynamics in pelagic and benthic food webs remain unclear. This study investigated the levels of p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE), polycyclic aromatic hydrocarbons (PAHs), and substituted PAHs (s-PAHs) in two plankton species, six invertebrate species, and ten fish species collected from Lake Dianchi in southern China. Relatively high concentrations of PAHs and s-PAHs were detected with total concentrations of 11...

Background: An increased prevalence of gastric premalignant abnormalities was reported among relatives of gastric cancer (GC) patients, with rather unexplored clinical significance. Methods: In Swedish computerized pathology registers, we identified, as 'index' persons 232 681 patients who were born after 1931 and underwent endoscopic examination with stomach biopsy between 1979 and 2014. Through linkage with the Multi-Generation Register, we compiled a cohort consisting of 903 337 first-degree relatives of these biopsied patients...

We propose a new regulation mechanism based on the idea of the "common stomach" to explain several aspects of the resilience and homeostatic regulation of honeybee colonies. This mechanism exploits shared pools of substances (pollen, nectar, workers, brood) that modulate recruitment, abandonment and allocation patterns at the colony-level and enable bees to perform several survival strategies to cope with difficult circumstances: Lack of proteins leads to reduced feeding of young brood, to early capping of old brood and to regaining of already spent proteins through brood cannibalism...

Titanium dioxide (TiO2) particles are used in some food products to alter their optical properties, such as whiteness or brightness. These additives typically contain a population of TiO2 nanoparticles (d < 100 nm), which has led to concern about their potential toxicity. The objective of this study was to examine the impact of TiO2 particles on the gastrointestinal fate of oil-in-water emulsions using a simulated gastrointestinal tract (GIT) that includes mouth, stomach, and small intestine phases...
