| 1 | Helicobacter pylori in human health and disease:Mechanisms for local gastric and systemic effects显示文摘Helicobacter pylori(H. pylori) is present in roughly 50% of the human population worldwide and infection levels reach over 70% in developing countries. The infection has classically been associated with different gastro-intestinal diseases, but also with extra gastric diseases. Despite such associations, the bacterium frequently persists in the human host without inducing disease, and it has been suggested that H. pylori may also play a beneficial role in health. To understand how H. pylori can produce such diverse effects in the human host, several studies have focused on understanding the local and systemic effects triggered by this bacterium. One of the main mechanisms by which H. pylori is thought to damage the host is by inducing local and systemic inflammation. However, more recently, studies are beginning to focus on the effects of H. pylori and its metabolism on the gastric and intestinal microbiome. The objective of this review is to discuss how H. pylori has co-evolved with humans, how H. pylori presence is associated with positive and negative effects in human health and how inflammation and/or changes in the microbiome are associated with the observed outcomes. | Denisse Bravo Anilei Hoare Cristopher Soto Manuel A Valenzuela Andrew FG Quest | 2018 | World Journal of Gastroenterology2018,24,28: | 32 |
| 2 | Helicobacter pylori-induced inflammation and epigenetic changes during gastric carcinogenesis显示文摘The sequence of events associated with the development of gastric cancer has been described as 'the gastric precancerous cascade'. This cascade is a dynamic process that includes lesions, such as atrophic gastritis, intestinal metaplasia and dysplasia. According to this model, Helicobacter pylori(H. pylori) infection targets the normal gastric mucosa causing non-atrophic gastritis, an initiating lesion that can be cured by clearing H. pylori with antibiotics or that may then linger in the case of chronic infection and progress to atrophic gastritis. The presence of virulence factors in the infecting H. pylori drives the carcinogenesis process. Independent epidemiological and animal studies have confirmed the sequential progression of these precancerous lesions. Particularly long-term follow-up studies estimated a risk of 0.1% for atrophic gastritis/intestinal metaplasia and 6% in case of dysplasia for the long-term development of gastric cancer. With this in mind, a better understanding of the genetic and epigenetic changes associated with progression of the cascade is critical in determining the risk of gastric cancer associated with H. pylori infection. In this review, we will summarize some of the mostrelevant mechanisms and focus predominantly but not exclusively on the discussion of gene promoter methylation and mi RNAs in this context. | Manuel A Valenzuela Jimena Canales Alejandro H Corvalán Andrew FG Quest | 2015 | World Journal of Gastroenterology2015,21,45: | 33 |

| 4 | Label-free detection of single nanoparticles and biological molecules using microtoroid optical resonators显示文摘Single-molecule detection is one of the fundamental challenges of modern biology.Such experiments often use labels that can be expensive,difficult to produce,and for small analytes,might perturb the molecular events being studied.Analyte size plays an important role in determining detectability.Here we use laser-frequency locking in the context of sensing to improve the signal-to-noise ratio of microtoroid optical resonators to the extent that single nanoparticles 2.5 nm in radius,and 15.5 kDa molecules are detected in aqueous solution,thereby bringing these detectors to the size limits needed for detecting the key macromolecules of the cell.Our results,covering several orders of magnitude of particle radius(100 nm to 2 nm),agree with the‘reactive’model prediction for the frequency shift of the resonator upon particle binding.This confirms that the main contribution of the frequency shift for the resonator upon particle binding is an increase in the effective path length due to part of the evanescent field coupling into the adsorbed particle.We anticipate that our results will enable many applications,including more sensitive medical diagnostics and fundamental studies of single receptor–ligand and protein–protein interactions in real time. | Judith Su Alexander FG Goldberg Brian M Stoltz | 2016 | Light(Science & Applications)2016,5,1: | 20 |
| 5 | Improving the outcomes in gastric cancer surgery显示文摘Gastric cancer remains a significant health problem worldwide and surgery is currently the only potentially curative treatment option. Gastric cancer surgery is generally considered to be high risk surgery and fiveyear survival rates are poor,therefore a continuous strive to improve outcomes for these patients is warranted. Fortunately,in the last decades several potential advances have been introduced that intervene at various stages of the treatment process. This review provides an overview of methods implemented in pre-,intra- and postoperative stage of gastric cancer surgery to improve outcome. Better preoperative risk assessment using comorbidity index(e.g.,Charlson comorbidity index),assessment of nutritional status(e.g.,short nutritional assessment questionnaire,nutritional risk screening- 2002) and frailty assessment(Groningen frailty indicator,Edmonton frail scale,Hopkins frailty) was introduced. Also preoperative optimization of patients using prehabilitation has future potential.Implementation of fast-track or enhanced recovery after surgery programs is showing promising results,although future studies have to determine what the exact optimal strategy is.Introduction of laparoscopic surgery has shown improvement of results as well as optimization of lymph node dissection.Hyperthermic intraperitoneal chemotherapy has not shown to be beneficial in peritoneal metastatic disease thus far.Advances in postoperative care include optimal timing of oral diet,which has been shown to reduce hospital stay.In general,hospital volume,i.e.,centralization,and clinical audits might further improve the outcome in gastric cancer surgery.In conclusion,progress has been made in improving the surgical treatment of gastric cancer.However,gastric cancer treatment is high risk surgery and many areas for future research remain. | Juul JW Tegels Michiel FG De Maat Karel WE Hulsewé Anton GM Hoofwijk Jan HMB Stoot | 2014 | World Journal of Gastroenterology2014,20,38: | 16 |
| 6 | Effect of fatty acids on poly-amine contents and Na^+/H^+ antiport activity in PM vesicles isolated from roots of barley under salt stress显示文摘With 200 mmol/L NaCl treatment on barley cultivar 'Jian 4' (Hordeum vulgare L. cv. J4) seedlings for 6 d, the contents of covalently and noncovalently conjugated polyamines (PAs) and activities of H+-ATPase in plasma membrane (PM) vesicles isolated from the roots decreased remarkably. Moreover, the activity of Na+/H+ antiport was detected first in PM vesicles. The results showed that the decrease in the contents of membrane phospholipid, noncovalently conjugated PAs and activity of H+-ATPase caused by NaCl could be restored partially by application of 1 mmol/L stearic acid (C16:0) and linoleic acid (C18:2), and C18:2 was more effective than C16:0. In addition, a reduction in the contents of covalently conjugated PAs was only reversed partially in the presence of C18:2. Furthermore, Na+/H+ antiport activity was strengthened by exogenous C16:0 and C18:2, and C18:2 was more effective than C16:0. The correlative analysis suggested that, after application of C16:0 and C18:2 under salt stress, there was a | Zhao, FG Shu, HR | 2002 | Chinese Science Bulletin2002,47,14: | 3 |
