To maintain energy homeostasis, orexigenic (appetite-inducing) and anorexigenic (appetite suppressing) brain systems functionally interact to regulate food intake. Within the hypothalamus, neurons that express agouti-related protein (AgRP) sense orexigenic factors and orchestrate an increase in food-seeking behavior. In contrast, calcitonin gene-related peptide (CGRP)-expressing neurons in the parabrachial nucleus (PBN) suppress feeding. PBN CGRP neurons become active in response to anorexigenic hormones released following a meal, including amylin, secreted by the pancreas, and cholecystokinin (CCK), secreted by the small intestine...

Gastric cancer exhibits a poor prognosis and is the third most common cause of cancer death worldwide. Chemotherapy of metastatic gastric cancer is based on combinations of platinum drugs and fluoropyrimidines, with added agents. Oxoplatin is a stable oral platinum(IV) prodrug which is converted to a highly active tetrachlorido(IV) complex under acidic conditions. In the present work, we studied the cytotoxic effects of oxoplatin against a panel of four gastric cancer cell lines in vitro. Furthermore, the role of HSP90 in chemoresistance of these lines was investigated using the specific inhibitor ganetespib...

BACKGROUND: Adequate muscle relaxation is important for ensuring optimal conditions for intubation. Although acceleromyography of the adductor pollicis muscle is commonly used to assess conditions for intubation, we hypothesized that acceleromyography of the trapezius is more indicative of optimal intubating conditions. The primary outcome was the difference between both measurement sites with regard to prediction of good or acceptable intubating conditions. METHODS: Neuromuscular blockade after injection of rocuronium 0...

Zygomycosis refers to invasive fungal infections caused by fungi belonging to the phylum zygomycota. Infections generally occur in immunocompromised individuals. The following case is of a previously healthy 56 year-oldmale admitted to the hospital following a motor vehicle accident. During his hospitalization, there was a significant drop in hemoglobin with no obvious source of bleeding. This prompted the clinician to insert a nasogastric tube which returned at least 2 liters of black fluid and led to an upper gastrointestinal endoscopy...

Upper Gastrointestinal (GI) pseudomelanosis is an uncommon entity characterized by endoscopic visualization of speckled dark mucosal pigmentation. While described in the rectum and colon, 'melanosis' or more aptly 'pseudomelanosis' is rare in the duodenum and exceedingly rare in the stomach. Five cases of pseudomelanosis were encountered at our department. Four females and one male were diagnosed, with a mean age of 70 years. All patients exhibited duodenal pseudomelanosis, with one demonstrating gastric antral pseudomelanosis as well...

Ischemic necrosis is a feared complication of acute gastric volvulus, occurring in 11% of patients presenting with the condition and responsible for mortality in 30%. In such cases, there are few well-validated options for surgical reconstruction. We present the case of a 77-year-old woman with intraabdominal mesenteroaxial gastric volvulus with segmental ischemic gastric necrosis who underwent wedge gastrectomy and hand-sewn gastrogastrostomy. She did well postoperatively and experienced no significant gastrointestinal complications...

BACKGROUND: The "perfect" bariatric procedure remains the topic of debate. The aim of this study is to compare the safety and outcome of laparoscopic Roux-en-Y gastric bypass (LRYGB) to those of laparoscopic sleeve gastrectomy (LSG) and adjustable gastric band (AGB) in a single centre, amongst those patients who made their own choice of which procedure they prefer. METHODS: After the multi-disciplinary team's assessment, the patients could make their own choice of procedures (self-selected, SS), unless medical/surgical conditions limited this (medically restricted, MR)...

A 62-year-old woman was admitted to our hospital with septic shock due to left submandibular osteomyelitis and cellulitis. Her condition improved following tooth extraction, drainage, and the administration of antibiotics. However, on the 4th day of hospitalization, she went into hemorrhagic shock after defecating a massive tarry stool. Emergency esophagogastroduodenoscopy (EGD) was performed. We found a giant ulcer at the antral greater curvature of the stomach. Computed tomography (CT) revealed that the gastric ulcer had penetrated the pancreas...

Breast metastasis is extremely unusual in gastric cancer patients worldwide. We herein report the case of a 39-year-old female Chinese patient presenting with symptoms of inflammation in the left breast. A biopsy did not reveal any evidence of malignancy. A modified radical mastectomy was performed and the postoperative pathological examination revealed infiltration by signet ring cell gastric carcinoma. A review of the Chinese literature was performed, and a total of 16 patients with breast metastasis from gastric carcinoma have been reported from 1990 onwards...

BACKGROUND: Rikkunshito, one of the Kampo medicines, is widely prescribed as a remedy for various upper gastrointestinal syndromes. The effect of rikkunshito is related to endogenous ghrelin and its active ingredient atractylodin enhances ghrelin receptor signaling. Kampo medicines are traditionally administered before or between meals; however, no definitive benefit of the timing of administration has been proven yet. To clarify the influence of food on the pharmacological action of rikkunshito, we investigated the gastric motor activity and pharmacokinetic profiles of atractylodin after the administration of rikkunshito in fasted and fed rats...

In this work, a fixed-dose combination of gabapentin and flurbiprofen formulated as multilayer tablets has been designed, developed and studied in vitro and in vivo. The aim was to construct a single dosage form of the two drugs, able to perform a therapeutic program involving three release kinetics and two delivery sites, i.e., immediate release of gabapentin, intra-gastric prolonged release of gabapentin and intestinal (delayed) release of flurbiprofen. An oblong three-layer tablet was manufactured having as top layer a floating hydrophilic polymeric matrix for gastric release of gabapentin, as middle layer a disintegrating formulation for immediate release of a gabapentin loading dose and as bottom layer, an uncoated hydrophilic polymeric matrix, swellable but insoluble in gastric fluids, for delayed and prolonged release of flurbiprofen in intestinal environment...

Majority of bioequivalence studies are conducted in healthy volunteers. It has been argued that bioequivalence may not necessarily hold true in relevant patient populations due to a variety of reasons which affect one formulation more than the other for instance in achlorhydric patients where elevated gastric pH may lead to differential effects on formulations which are pH-sensitive with respect to release or dissolution. We therefore examined achlorhydria-related disparity in bioequivalence of levothyroxine and nifedipine formulations using virtual bioequivalence within a physiologically-based pharmacokinetic (PBPK) modelling framework...

The objective of the present study was to determine the effect of nitrates on the incidence of gastrointestinal (GI) cancer development. Nitrate converted to nitrite under reducing conditions of gut results in the formation of N-nitrosamines which are linked to an increased gastric cancer risk. A population of 234 individuals with 78 cases of GI cancer and 156 controls residing at urban and rural settings in Nagpur and Bhandara districts of India were studied for 2 years using a case-control study. A detailed survey of 16 predictor variables using Formhub software was carried out...
