In this brief review we summarize the current fndings relative to the discovery of a small peptide ligand, phoenixin (PNX). Using a bioinformatic approach, two novel peptides PNX-14 and PNX-20 containing 14 and 20 amino acids, respectively, were isolated from diverse tissues including the brain, heart, lung and stomach. Mass spectrometry analysis identified a major and minor peak corresponding to PNX-14 and PNX-20, in rat or mouse spinal cord extracts. With the use of a rabbit polyclonal antiserum, phoenixin immunoreactivity (irPNX) was detected in discrete areas of the rodent brain including several hypothalamic subnuclei and dorsal motor nucleus of the vagus...

Essential oils from Origanum spp. exhibit antioxidant and antimicrobial activities making them suitable for use as food additives. The incorporation of oregano essential oil in active food packaging is under study; however, it has been not authorized for this purpose thus far. In order to fulfill the requirements of the European Food Safety Authority (EFSA), the aim of the present study was to determine the genotoxic potential of oregano essential oil using both the micronucleus (MN) test and comet (standard and enzyme-modified) assays in Wistar rats treated with 50, 100, or 200 mg/kg body weight administered daily for 90 days...

Obesity is the pandemic of the 21st century. Obesity comorbidities, including hypertension, dyslipidaemia and glucose intolerance define metabolic syndrome, which increases mortality risk and decreases the quality of life. Compared with lifestyles (diet and physical activity) and pharmacological interventions, bariatric surgery is by far the most effective treatment for obesity and its comorbidities. This minimally invasive surgical treatment is based on an increase of satiety (by hormonal regulation and decreasing stomach volume) or a decrease in nutrient retention (gastric and/or intestinal resection)...

Selenium (Se) is a dietary essential trace element with important biological roles. It is a nutrient related to the complex metabolic and enzymatic functions. Organoselenium compounds have been reported to have anti-ulcer activity and used as drug for the treatment of gastrointestinal disorders. The antiulcer activity of binapthyl diselenide (NapSe)2 was investigated in ethanol-induced gastric lesions in rats. A number of markers of oxidative stress were examined in rats stomach including thiobarbituric acid reactive species (TBARS), catalase (CAT), superoxide dismutase (SOD), non-protein thiol groups (NPSH) and ascorbic acid...

Dairy heifers were subjected to a non-life-threatening challenge designed to induce ruminal acidosis by feeding grain and sugar. Large among animal variation in clinical signs of acidosis, rumen metabolite concentrations, and the rumen microbiome occurred. This exploratory study investigates sources of the variation by examining associations between the genome, metabolome, and microbiome, albeit with a limited population. The broader objective is to provide a rationale for a larger field study to identify markers for susceptibility to ruminal acidosis...

Background: Colon-targeted oral nanoparticles (NPs) have emerged as an ideal, safe, and effective therapy for ulcerative colitis (UC) owing to their ability to selectively accumulate in inflamed colonic mucosa. Cyclosporine A (CSA), an immunosuppressive agent, has long been used as rescue therapy in severe steroid-refractory UC. In this study, we developed CSA-loaded dual-functional polymeric NPs composed of Eudragit® FS30D as a pH-sensitive polymer for targeted delivery to the inflamed colon, and poly(lactic-co-glycolic acid) (PLGA) as a sustained-release polymer...

Osteoblast activating peptide (OBAP) is a newly discovered peptide detected in the rat stomach, which has a major role in osteogenesis. Recently, we revealed its localization in the parietal cells of the rat stomach. There have been no data regarding OBAP expression in the kidney, despite its role in calcium reabsorption in renal tubules. The current study aimed to inspect the expression of OBAP in the kidney of twelve 10-week-old male C3H/HeNJc1 mice using immunohistochemistry, and immunoelectron microscopic localization...

The retroperitoneum space comprises anterior pararenal space, perirenal space and posterior pararenal space. Pancreas is a retroperitoneal organ and located in the anterior pararenal space of the retroperitoneum. Left and right sides anterior pararenal space are potentially communicated, which contains many adipose tissues and a little connective tissues. The exacerbation of acute pancreatitis results in the lesion spreading into adjacent area of pancreas in the retroperitoneal space. In addition, the lesion could spread into bare area of stomach, posterior colonic region, subperitoneal space and pelvic retroperitoneal space through the same anatomical space or communicating space...

With an increasing trend of patients with young-onset colorectal cancer (CRC), risks of second primary cancers (SPCs) among them become a concerning issue. We aimed to define the detailed risk and site-distributed patterns of SPCs in young CRC individuals (age ≤50). A population-based cohort were identified from the Surveillance, Epidemiology, and End Results database between 1973 and 2013. Standardized incidence ratios (SIRs) and absolute excess risk (AER) were calculated to assess the risk for SPCs compared with the general population...

BACKGROUND: The use of an electromagnetic placement device (EMPD) can allow trained clinicians to safely perform small-bowel feeding tube (SBFT) placement at the bedside. Before initiation of enteral nutrition, most facilities require a radiology confirmation of tube placement. Requirement of X-ray confirmation delays the start of nutrition and leads to increased costs and utilization of resources. The purpose of this study was to determine the rate of agreement between clinician interpretation of SBFT placement using the EMPD images and X-ray confirmation on tip of SBFT placement...

Incidence of upper gastrointestinal cancers of the oesophagus and stomach show a strong unexplained male predominance. Hormonal and reproductive factors have been associated with upper gastrointestinal cancers in women but there is little available data on men. To investigate this, we included 219,425 men enrolled in the UK Biobank in 2006-2010. Baseline assessments provided information on hormonal and reproductive factors (specifically hair baldness, number of children fathered, relative age at first facial hair and relative age voice broke) and incident oesophageal or gastric cancers were identified through linkage to UK cancer registries...
