Preterm birth is a global health issue that can induce lifelong medical sequela. Presently, at least one in ten newborns are born prematurely. At birth, preterm newborns exhibit higher levels of oxidative stress (OS) due to the inability to face the oxygen rich environment in which they are born into. Moreover, their immature respiratory, digestive, immune and antioxidant defense systems, as well as the potential numerous medical interventions following a preterm birth, such as oxygen resuscitation, nutrition, phototherapy and blood transfusion further contribute to high levels of OS...

Due to different disease background of gastric stump cancer(GSC) patients (benign or malignant lesion, reconstruction of digestive tract, etc.), the GSC surgical procedure and the difficulty of lymphadenectomy are also different. The extent of radical lymphadenectomy for gastric stump cancer should extend beyond D2 lymphadenectomy, according to the different backgrounds of initial disease, reconstructions, and tumor location. A lymphadenectomy should include the lymph nodes in anterior (No.17) and posterior (No...

Gastric stump cancer was initially defined as a carcinoma of the stomach occurring more than 5 years after surgery for gastric or duodenal benign disease. In recent years, as the number of total gastrectomy for benign disease has gradually decreased and the gastric cancer detection and operation rate have annually increased, residual recurrence of primary gastric cancer more than 10 years after gastric cancer surgery has also been considered as gastric stump cancer. The incidence of gastric stump cancer is increasing annually...

The pancreas is made from two distinct components: the exocrine pancreas, a reservoir of digestive enzymes, and the endocrine islets, the source of the vital metabolic hormone insulin. Human islets possess limited regenerative ability; loss of islet β-cells in diseases such as type 1 diabetes requires therapeutic intervention. The leading strategy for restoration of β-cell mass is through the generation and transplantation of new β-cells derived from human pluripotent stem cells. Other approaches include stimulating endogenous β-cell proliferation, reprogramming non-β-cells to β-like cells, and harvesting islets from genetically engineered animals...

BACKGROUND: Gastrointestinal cancers are among the most recognised oncological diseases in well-developed countries. Tumours located in the digestive tract may cause the fast occurrence of malnutrition. MAIN TEXT: The perioperative period is a special time for systemic metabolism. Thanks to published guidelines, early universal control nutritional status before treatment, patients may have a chance to get suitable nutritional intervention. Although the first line of the intervention-nutritional consultation as well as the fortification of a diet and oral nutritional support (ONS)-is not debatable, in a case of inability of undergoing an oral feeding, the choice of the way of administration in patients before a surgery may represent a serious clinical obstacle...

The gastrointestinal (GI) barrier serves a critical role in survival and overall health of animals and humans. Several layers of barrier defense mechanisms are provided by the epithelial, immune and enteric nervous systems. Together they act in concert to control normal gut functions (e.g., digestion, absorption, secretion, immunity, etc.) whereas at the same time provide a barrier from the hostile conditions in the luminal environment. Breakdown of these critical GI functions is a central pathophysiological mechanism in the most serious GI disorders in pigs...

Porphyromonas gingivalis is an anaerobic, Gram-negative oral pathogen associated with chronic periodontitis. P. gingivalis has an obligate requirement for heme which it obtains from the host. Heme availability has been linked to disease initiation and progression. In this study we used continuous culture of the bacterium to determine the effect of heme limitation and excess on the P. gingivalis proteome. Four biological replicates of whole cell lysate (WCL) and outer membrane vesicle (OMV) samples were digested with trypsin and analysed by tandem mass spectrometry and MaxQuant label-free quantification...

Background: Probiotics are live microorganisms which are beneficial bacteria that are normal flora of the digestive system which, in determined amounts, show beneficial effects on host health, and can balance gastrointestinal microflora. Digestive tract diseases such as diarrhea are one of the major causes of child mortality in developing countries. Different pathotypes of Escherichia coli cause diarrhea that affects children, therefore reduction of these colonization strains in humans or animals can decline gastrointestinal disorders such as diarrhea...

Type-1 diabetes (T1D) is a metabolic disease involving the autoimmune destruction of insulin-producing pancreatic beta cells. It is often diagnosed by the detection of autoantibodies, typically those recognizing insulin itself or the 65-kDa isoform of glutamic acid decarboxylase (GAD65). Oral insulin can be used to induce systemic immunological tolerance and thus prevent or delay the onset of T1D, suggesting that combination treatments with other autoantigens such as GAD65 could be even more successful. GAD65 has induced oral tolerance and prevented T1D in preclinical studies but it is difficult to produce in sufficient quantities for clinical testing...

Esophageal bronchogenic cysts are extremely rare. Here we report a case of massive upper digestive tract hematoma and bronchogenic cyst mimicking aortic dissection that was safely removed without esophagectomy. A 30-year-old man was referred to our hospital for the treatment of a mediastinal cystic tumor located in the submucosa of the distal esophagus. His chief complaints were dysphagia > 1 week and severe persistent upper abdominal pain mimicking aortic dissection with constant vomiting for 1 day after gastroscopy examination...

Modern genomics has shed light on many entomopathogenic fungi and expanded our knowledge widely; however, little is known about the genomic features of the insect-commensal fungi. Harpellales are obligate commensals living in the digestive tracts of disease-bearing insects (black flies, midges, and mosquitoes). In this study, we produced and annotated whole-genome sequences of nine Harpellales taxa and conducted the first comparative analyses to infer the genomic diversity within the members of the Harpellales...

OBJECTIVE: To study the clinical effect and mechanism of hemoperfusion (HP) in the treatment of children with severe abdominal Henoch-Schönlein purpura (HSP). METHODS: A total of 24 children with severe abdominal HSP were divided into two groups: conventional treatment and HP (n=12 each). Ten healthy children who underwent physical examination were enrolled as the control group. Before and after treatment, chemiluminescence was used to measure the serum levels of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α); thiobarbituric acid colorimetry was used to measure the plasma level of malondialdehyde (MDA); the hydroxylamine method was used to measure the plasma level of superoxide dismutase (SOD); chemical colorimetry was used to measure the plasma level of total anti-oxidant capability (T-AOC)...

From 2004 until 2016, 21 Père David's deer (Elaphurus davidianus) have died for unknown reason at Zoo Duisburg. These deer, also known as milu, have succumbed from a myopathy that occurred seasonally in autumn and in spring. The clinical signs shown by the animals, closely resembles those of a disease called equine atypical myopathy (EAM), which is formerly known in horses. The cause for EAM in Europe was found in the ingestion of hypoglycin A, contained in samaras and seedlings of the sycamore maple tree (Acer pseudoplatanus)...

Human intestinal microbes participate actively at the interface of diet, nutrition, and overall health status. These biodiverse communities of microorganisms have a broader metabolic repertoire compared with their host, and they are able to synthesize and degrade substrates that would be otherwise unavailable. In recent years, we have recognized that healthy microbial communities are important for energy harvest and the regulation of body systems outside the digestive tract. Microbial dysbiosis, however, has been implicated in a number of human disorders, including obesity and inflammation...

Short bowel syndrome with intestinal failure is a rare disease with a massive impairment in quality of life, requiring a multidisciplinary team approach to medical, surgical, and nutritional therapy. Current pharmacological and surgical therapeutic options are limited; an important cornerstone is enteral and parenteral nutrition. The changed physiology of carbohydrate digestion plays a major role in the adaptation process and can be a target for specific enteral nutrition interventions. An important prognostic factor is the preservation of at least portions of the colon in continuity with small bowel...

Proteinase pattern of honeybee prepupae from healthy and American Foulbrood infected bees investigated by zymography: The numbered spots (figure 4) were excised from the gels and they were individually transferred to a 1.5 mL microcentrifuge tube. Spots were destained and proteins digested as reported by Dani et al. 40. Each peptide mixture was submitted to capillary-LC-μESI-MS/MS analysis on an Ultimate 3000 HPLC (Dionex, San Donato Milanese, Milano, Italy) coupled to a LTQ Orbitrap mass spectrometer (Thermo Fisher, Bremen, Germany). Peptides were concentrated on a precolumn cartridge PepMap100 C18 (300 μm i.d. × 5 mm, 5 μm, 100 Å, LC Packings Dionex) and then eluted on a homemade capillary column packed with Aeris Peptide XB-C18 phase (180 μm i.d. × 15 cm, 3.6 μm, 100 Å, Phenomenex, Torrance, CA, USA) at 1 μl/min. The loading mobile phases were: 0.1% TFA in H 2 O (phase A) and 0.1% TFA in CH 3 CN (phase B). The elution mobile phases composition was: H 2 O 0.1% formic acid/CH 3 CN 97/3 (phase A) and CH 3 CN 0.1% formic acid/ H 2 O 97/3 (phase B). The elution program was: 0 min, 4% B; 10 min, 40% B; 30 min, 65% B; 35 min, 65% B; 36 min, 90% B; 40 min, 90% B; 41 min, 4%B; 60 min, 4% B. Mass spectra were acquired in positive ion mode, setting the spray voltage at 1.8 kV, the capillary voltage and temperature respectively at 45 V and 200°C, and the tube lens at 130 V. Data were acquired in data-dependent mode with dynamic exclusion enabled (repeat count 2, repeat duration 15 s, exclusion duration 30 s); survey MS scans were recorded in the Orbitrap analyzer in the mass range 300-2000 m/z at a 15,000 nominal resolution at m/z = 400; then up to three most intense ions in each full MS scan were fragmented (isolation width 3 m/z, normalized collision energy 30) and analyzed in the IT analyzer. Monocharged ions did not trigger MS/MS experiments.

American foulbrood disease (AFB) is the main devastating disease that affects honeybees' brood, caused by Paenibacillus larvae. The trend of the research on AFB has addressed the mechanisms by which P. larvae bacteria kill honeybee larvae. Since prepupae could react to the infection of AFB by increasing protease synthesis, the aim of this work was to compare protease activity in worker prepupae belonging to healthy colonies and to colonies affected by AFB. This investigation was performed by zymography. In gel, proteolytic activity was observed in prepupae extracts belonging to the healthy colonies...

Liquid biopsies using body fluids have gained much attention in recent years due to their multiple advantages in clinical diagnosis, such as less/non-invasive collection, suitability for longitudinal disease monitoring, and better representation of tumor heterogeneity. As an attractive choice for liquid biopsy, urine proteins and their post-translational modifications (PTMs) have the potential to offer significant insights into physiological variations and pathological changes in the human body. However, due to the intrinsically large variability of urine proteins and their PTMs among different individuals, there is a high demand for strategies for high-throughput analysis of a large number of samples to obtain a comprehensive view and a reliable reference interval of the urine proteome...
