1Advances in nutritional therapy in inflammatory boweldiseases:Review显示文摘Inflammatory bowel diseases(IBD), including ulcerative colitis and Crohn's disease are chronic, life-long, and relapsing diseases of the gastrointestinal tract. Currently, there are no complete cure possibilities, but combined pharmacological and nutritional therapy may induce remission of the disease. Malnutrition and specific nutritional deficiencies are frequent among IBD patients, so the majority of them need nutritional treatment, which not only improves the state of nutrition of the patients but has strong anti-inflammatory activity as well. Moreover, some nutrients, from early stages of life are suspected as triggering factors in the etiopathogenesis of IBD. Both parenteral and enteral nutrition is used in IBD therapy, but their practical utility in different populations and in different countries is not clearly established, and there are sometimes conflicting theories concerning the role of nutrition in IBD. This review presents the actual data from research studies on the influence of nutrition on the etiopathogenesis of IBD and the latest findings regarding its mechanisms of action. The use of both parenteral and enteral nutrition as therapeutic methods in induction and maintenance therapy in IBD treatment is also extensively discussed. Comparison of the latest research data, scientific theories concerning the role of nutrition in IBD, and different opinions about them are also presented and discussed. Additionally, some potential future perspectives for nutritional therapy are highlighted.Andrzej Wędrychowicz Andrzej Zając Przemysław Tomasik 2016World Journal of Gastroenterology2016,22,3:21

5Heterotopic pancreatic tissue in the gastric cardia: A case report and literature review显示文摘The heterotopic pancreas, which is usually described as an untypical presence of pancreatic tissue without any anatomic or vascular continuity with the pancreas, is relatively rare. Clinical manifestations may include bleeding, inflammation, pain and obstruction; however, in most cases it remains silent and is diagnosed during autopsy. Here, we report a case of ectopic pancreatic lesion located in the gastric cardia. The patient was a 73-year-old woman who had a history(over four months) of chronic epigastric pain accompanied by heartburn. Esophagogastroduodenoscopy revealed inflammatory changes throughout the stomach and lower esophagus, as well as a flat polypoid mass with benign features located in the gastric cardia, approx. 10 mm below the 'Z' line, measuring approx. 7 mm in diameter. Endoscopic biopsy forceps were used to remove the lesion. Histological examination of the lesion revealed the presence of heterotopic pancreatic tissue in the gastric mucosa. On the basis of the presented case, we suggest that pancreatic ectopia should be a part of differential diagnosis, not only when dealing with submucosal gastric lesions, but also with those that are small, flat and/or untypically located.Rafa?

6Development tendencies of moulding and core sands显示文摘Further development of the technology for making moulding and core sands will be strictly limited by tough requirements due to protection of the natural environment. These tendencies are becoming more and more tense, so that we will reach a point when even processes, that from technological point of view fulfill high requirements of the foundry industry, must be replaced by more ecologically-friendly solutions. Hence, technologies using synthetic resins as binding materials will be limited. This paper presents some predictable development tendencies of moulding and core sands. The increasing role of inorganic substances will be noticed, including silicate binders with significantly improved properties, such as improved knock-out property or higher reclamation strength. Other interesting solutions might also be moulding sands bonded by geo-polymers and phosphate binders or salts and also binders based on degradable biopolymers. These tendencies and the usefulness of these binders are put forward in this paper.Stanisaw M.Dobosz Petr Jelinek Katarzyna Major-Gabry 2011China Foundry2011,8,4:11
7Hormonal protection in acute pancreatitis by ghrelin, leptin and melatonin显示文摘Acute pancreatitis is a nonbacterial disease of the pancreas.The severe form of this ailment is characterized by high mortality.Whether acute pancreatitis develops as the severe type or resolves depends on the intensity of the inflammatory process which is counteracted by the recruitment of innate defense mechanisms.It has been shown that the hormones ghrelin,leptin and melatonin are able to modulate the immune function of the organism and to protect the pancreas against inflammatory damage.Experimental studies have demonstrated that the application of these substances prior to the induction of acute pancreatitis significantly attenuated the intensity of the inflammation and reduced pancreatic tissue damage.The pancreatic protective mechanisms of the above hormones have been related to the mobilization of non-specific immune defense,to the inhibition of nuclear factor kappa B and modulation of cytokine production,to the stimulation of heat shock proteins and changes of apoptotic processes in the acinar cells,as well as to the activation of antioxidant system of the pancreatic tissue.The protective effect ofghrelin seems to be indirect and perhaps dependent on the release of growth hormone and insulin-like growth factor 1.Leptin and ghrelin,but not melatonin,employ sensory nerves in their beneficial action on acute pancreatitis.It is very likely that ghrelin,leptin and melatonin could be implicated in the natural protection of the pancreatic gland against inflammatory damage because the blood levels of these substances increase in the initial phase of pancreatic inflammation.The above hormones could be a part of the innate resistance system which might remove noxious factors and could suppress or attenuate the inflammatory process in the pancreas.Jolanta Jaworek Stanis?aw Jan Konturek 2014World Journal of Gastroenterology2014,20,45:10
8Two gap-free reference genomes and a global view of the centromere architecture in rice显示文摘Rice(Oryza sativa),a major staple throughout the world and a model system for plant genomics and breeding,was the first crop genome sequenced almost two decades ago.However,reference genomes for all higher organisms to date contain gaps and missing sequences.Here,we report the assembly and analysis of gap-free reference genome sequences for two elite O.sativa xian/indica rice varieties,Zhenshan 97 and Minghui 63,which are being used as a model system for studying heterosis and yield.Gap-free reference genomes provide the opportunity for a global view of the structure and function of centromeres.We show that all rice centromeric regions share conserved centromere-specific satellite motifs with different copy numbers and structures.In addition,the similarity of CentO repeats in the same chromosome is higher than across chromosomes,supporting a model of local expansion and homogenization.Both genomes have over 395 non-TE genes located in centromere regions,of which∼41%are actively transcribed.Two large structural variants at the end of chromosome 11 affect the copy number of resistance genes between the two genomes.The availability of the two gap-free genomes lays a solid foundation for further understanding genome structure and function in plants and breeding climate-resilient varieties.Jia-Ming Song Wen-Zhao Xie Shuo Wang Yi-Xiong Guo Dal-Hoe Koo Dave Kudrna Chenbo Gong Yicheng Huang Jia-Wu Feng Wenhui Zhang Yong Zhou Andrea Zuccolo Evan Long Seunghee Lee Jayson Talag Run Zhou Xi-Tong Zhu Daojun Yuan Joshua Udall Weibo Xie Rod AWing Qifa Zhang Jesse Poland Jianwei Zhang Ling-Ling Chen 2021Molecular Plant2021,14,10:9
9Impact of diet on long-term decline in gastric cancer incidence in Poland显示文摘AIM:To examine the relationship between the trends in food consumption and gastric cancer morbidity in Poland.METHODS:The study was based on gastric cancer incidence rates and consumption of vegetables,fruit,vitamin C and salt in Poland between 1960 and 2006.Food consumption data were derived from the national food balance sheets or household budget surveys.Spearman correlation coefficients were used to estimate the relationship between the variables.RESULTS:A negative correlation was found between vegetables(-0.70 both for men and women;P < 0.0001),fruit(-0.65 and-0.66;P < 0.0001) and vitamin C(-0.75 and-0.74;P < 0.0001) consumption and stomach cancer incidence rates.The same applied to the availability of refrigerators in the household(-0.77 and-0.80;P < 0.0001).A decline in these rates could also be linked to reduction in salt intake.CONCLUSION:The decline of gastric cancer incidence probably resulted from increased consumption of vegetables,fruit and vitamin C and a decrease in salt consumption.Mirosaw Jarosz Wodzimierz Sekua Ewa Rychlik Katarzyna Figurska 2011World Journal of Gastroenterology2011,17,1:7

12Ghrelin and gastrin in advanced gastric cancer before and after gastrectomy显示文摘AIM: To investigate plasma ghrelin, gastrin and growth hormone secretagogue receptor (GHS-R) expression in advanced gastric cancer (GC) before and after resection. METHODS: Seventy subjects in whom endoscopy of the upper gastrointestinal tract was performed in the Department of General Surgery at Cracow University during the past decade: (1) 25 patients with GC associated with Helicobacter pylori (H. pylori) infection; (2) 10 patients with GC 4-5 years after (total or subtotal) gastrectomy; (3) 25 healthy H. pylori-negative controls, matched by age and BMI to the above two groups; and (4) 10 GC patients 4-5 years after total gastrectomy. Ghrelin and gastrin plasma concentrations were measured by specific radioimmunoassay under fasting conditions and postprandially at 60 and 90 min after ingestion of a mixed meal. GHS-R expression was examined in biopsy samples from intact healthy mucosa and GC tissue using semi-quantitative reverse transcription-polymerase chain reaction. RESULTS: In healthy controls, fasting plasma ghrelin levels were significantly elevated and declined markedly at 60 and 90 min after a mixed meal. The concomitant enhanced ghrelin, GHS-R and gastrin expression in GC tissue over that recorded in intact mucosa, and the marked rise in plasma gastrin in these subjects under fasting conditions indicate the role of these hormonal factors in GC formation. Fasting plasma levels and postprandial response of ghrelin and gastrin appear to be inversely correlated in healthy subjects. Feeding in the controls resulted in a significant fall in plasma ghrelin with a subsequent rise in plasma gastrin, but in H. pylori-positive GC patients submitted to total or distal gastrectomy, feeding failed to affect significantly the fall in plasma ghrelin that was recorded in these patients before surgery. Fasting ghrelin concentrations were significantly lower in patients 4-5 years after total gastrectomy compared to those in healthy controls and to these in GC patients before surgery. CONCLUSION: Elevated plasma gastrin and suppression of fasting ghrelin in patients with GC suggest the existence of a close relationship between these two hormones in gastric carcinogenesis.Anna Zub-Pokrowiecka Kazimierz Rembiasz Peter C Konturek Andrzej Budzyński Stanisaw J Konturek Marek Winiarski Wadysaw Bielański 2011World Journal of Gastroenterology2011,17,4:7

14Dietary and socio-economic factors in relation to Helicobacter pylori re-infection显示文摘AIM:To examine if dietary and socio-economic factors contribute to Helicobacter pylori(H pylori)re-infection. METHODS:The population of patients consisted of subjects in whom H pylori infection had been successfully treated in the past.Patients were divided into two groups:Ⅰ-examined group(111 persons with H pylori re-infection)andⅡ-control group(175 persons who had not been re-infected).The respondents were interviewed retrospectively on their dietary habits and socio-economic factors. RESULTS:A statistically significant lower frequency of fermented dairy products(P<0.0001),vegetables (P=0.02),and fruit(P=0.008)consumption was noted among patients with H pylori re-infection as compared to those who had not been re-infected. CONCLUSION:High dietary intake of probiotic bacteria,mainly Lactobacillus,and antioxidants,mainly vitamin C(contained in fruit and vegetables),might decrease the risk of H pylori re-infection.Mirosaw Jarosz Ewa Rychlik Magdalena Siuba Wioleta Respondek Magorzata Ryzko-Skiba Iwona Sajór Sylwia Gugaa Tomasz Bazejczyk Janusz Ciok 2009World Journal of Gastroenterology2009,15,9:6

16Systematic mechanism-orientated approach to chronic pancreatitis pain显示文摘Pain in chronic pancreatitis(CP) shows similarities with other visceral pain syndromes(i.e.,inflammatory bowel disease and esophagitis),which should thus be managed in a similar fashion.Typical causes of CP pain include increased intrapancreatic pressure,pancreatic inflammation and pancreatic/extrapancreatic complications.Unfortunately,CP pain continues to be a major clinical challenge.It is recognized that ongoing pain may induce altered central pain processing,e.g.,central sensitization or pro-nociceptive pain modulation.When this is present conventional pain treatment targeting the nociceptive focus,e.g.,opioid analgesia or surgical/endoscopic intervention,often fails even if technically successful.If central nervous system pain processing is altered,specific treatment targeting these changes should be instituted(e.g.,gabapentinoids,ketamine or tricyclic antidepressants).Suitable tools are now available to make altered central processing visible,including quantitative sensory testing,electroencephalograpy and(functional) magnetic resonance imaging.These techniques are potentially clinically useful diagnostic tools to analyze central pain processing and thus define optimum management approaches for pain in CP and other visceral pain syndromes.The present review proposes a systematic mechanism-orientated approach to pain management in CP based on a holistic view of the mechanisms involved.Future research should address the circumstances under which central nervous system pain processing changes in CP,and how this is influenced by ongoing nociceptive input and therapies.Thus we hope to predict which patients are at risk for developing chronic pain or not responding to therapy,leading to improved treatment of chronic pain in CP and other visceral pain disorders.Stefan AW Bouwense Marjan de Vries Luuk TW Schreuder Soren S Olesen Jens B Frokjær Asbjorn M Drewes Harry van Goor Oliver HG Wilder-Smith 2015World Journal of Gastroenterology2015,21,1:6
17Ability for Self-Pelletization of Iron Ores and Magnetite Concentrates显示文摘A procedure for evaluating the susceptibility of raw materials for the process of sintering of iron-ore mixes is presented.The procedure relies on the evaluation of the amount and quality of the finest grain fraction.The method is based on determination of particular grain fractions.For the grain less than 0.15 mm,the determination of the amount is performed using an IPS(Infrared Particles Sizer)grain size analyzer and for the grain larger than 0.15 mm,the fraction is determined using the(wet and dry)screening methods.This allows for quantity assessment of the quality of material in terms of its susceptibility to self-pelletizing by calculating Total Ability for Self-Pelletizing(TASP)index fT.The presented method,in combination with the grain size and chemical analyses,can serve for evaluation of suitability of raw material and mixes for the sintering process.Furthermore,the TASP index for 10 types of iron ores and concentrates was determined.The usability of the TASP index was verified by determination of its impact on yield of sintering process both in laboratory and in industry scale.Francik Przemysaw Jan Mróz 2011Journal of Iron and Steel Research(International)2011,18,6:5
