To estimate Helicobacter pylori (H. pylori) recurrence rate in Latin America, a region with a significant H. pylori prevalence and gastric cancer burden. METHODSPubMed, LILACS, SciELO, Cochrane databases and abstracts from relevant meetings were reviewed. Information collected included: Participants’ characteristics, recruitment strategy, diagnostic modality, treatment arms, follow-up and recurrence rates. Recurrence was calculated using 100-patients-year rates, and data were pooled using a random effects model. The I2 statistic assessed between study heterogeneity. Meta-regression analyses evaluated for effect modifying variables. RESULTSLiterature search yielded 163 articles. Twelve studies involving 4848 patients from 9 countries met inclusion criteria. Four hundred and thirty-two reinfections were recorded in 5487 person-years of follow-up. Pooled analysis showed a recurrence rate of 7.9 cases per 100 person-years (95%CI: 5.3-10.5). Meta-regression revealed that neither the antibiotic schema, a second antibiotic course, nor the diagnostic modality had an impact on the observed risk of recurrence. The recurrence rate in the first year after treatment, predominantly recrudescence, was 11.2 (6.1-16.4) per 100 patient years. Recurrence in subsequent years, was only 6.2 (3.8-8.7). CONCLUSIONH. pylori recurrence rates in Latin America are significant, and with geographic variability, yet are acceptable based upon the current literature for consideration of large scale intervention trials. Further research in Latin America is warranted to evaluate the efficacy, cost-effectiveness, and potential adverse outcomes of proposed eradication programs.

Dear Editor,Takeda G protein-coupled receptor 5(TGR5),also known as G protein-coupled bile acids(BAs)receptor 1(GPBAR1),1 belongs to the class A GPCR *** major TGR5-dependent actions of BAs include maintaining energy homeostasis,regulating glucose/lipids metabolism,as well as immunosuppressive properties.2 TGR5 is identified as a potential therapeutic target for protecting hepatocytes from bile acid overload,preventing atherosclerosis,and inhibiting macrophage inflammation due to its critical role in bile acid ***,elucidation of structural characteristics of TGR5 and its activation mechanism would benefit the discovery of therapeutic drugs for these metabolic disorders.

Taste interaction is a well-known phenomenon in sensory stodies,but how to quantify the magnitode of the effect of one tastant on other taste attribute(s)is still largely unsolved,let alone further explorations from a salivary biochemistry *** acquiring the individual taste threshold and evaluating the just noticeable difference(JND).this stody firstly established a quantitative method to assess the magnitude of taste interaction in a binary taste mixture by evaluating the concentration difference upon psychologically-comparable *** change of salty taste intensity(CSI)was therefore defined as the subtraction of JND using sour-salty taste stimulant from JND using pure salty taste stimulant,with a dimension of concentration in mmol/*** was then used to demonstrate how citric acid affected salty taste perception in a salty-sour binary taste mixture in 16 young and healthy *** of citric acid used in the binary taste mixtore were 0.***.0.09.0.***.0.24 and 0.40 mmolL,*** results showed that salty taste perception was enhanced(average CSI of 0.93 mmolL)when the citric acid concentration was low(at 0.05 and 0.09 mmolL).but with an increasing concentration of citric acid ranging from 0.14 to 0.40 mmol/L,this effect gradually turned from enhancement to suppression of salty taste perception(correspondingly a continoously decreasing CSI all the way down to an average of-2.94 mumol/L).It was also found that cystatin SN concentration in participants'unstimulated saliva samples was significantly negatively correlated with salty taste threshold(with and without the presence of citric acid),and it was one of the most significant factors affecting CSI,s shown in multiple regression *** anhydrase VI concentration in participants'unstimulated saliva sanples was also found to be significantly negatively correlated with salty taste recognition(with and without presence of citric acid).but it did not pose signific

Realizing high work hardening and thus elevated strength–ductility synergy are prerequisites for the practical usage of body-centered-cubic high entropy alloys(BCC-HEAs).In this study,we report a novel dynamic strengthening mechanism,martensitic twinning transformation mechanism in a metastable refractory element-based BCC-HEA(TiZrHf)Ta(at.%)that can profoundly enhance the work hardening capability,leading to a large uniform ductility and high strength *** from conventional transformation induced plasticity(TRIP)and twinning induced plasticity(TWIP)strengthening mechanisms,the martensitic twinning transformation strengthening mechanism combines the best characteristics of both TRIP and TWIP strengthening mechanisms,which greatly alleviates the strengthductility trade-off that ubiquitously observed in BCC structural *** characterization,carried out using X-ray diffraction(XRD)and electron back-scatter diffraction(EBSD)shows that,upon straining,α”(orthorhombic)martensite transformation,self-accommodation(SA)α”twinning and mechanicalα”twinning were activated *** electron microscopy(TEM)analyses reveal that continuous twinning activation is inherited from nucleating mechanical{351}type I twins within SA“{351}”typeⅡtwinnedα”variants on{351}twinning plane by twinning transformation through simple shear,thereby accommodating the excessive plastic strain through the twinning shear while concurrently refining the grain ***,consistent high work hardening rates of 2–12.5 GPa were achieved during the entire plastic deformation,leading to a high tensile strength of 1.3 GPa and uniform elongation of 24%.Alloy development guidelines for activating such martensitic twinning transformation strengthening mechanism were proposed,which could be important in developing new BCC-HEAs with optimal mechanical performance.

This work presents a review of the findings into the ability of a digitally based particle packing algorithm, called DigiPac, to predict bed structure in a variety of packed columns, for a range of generic pellet shapes frequently used in the chemical and process engineering industries. Resulting macroscopic properties are compared with experimental data derived from both invasive and non-destructive measurement techniques. Additionally, fluid velocity distributions, through samples of the resulting bed structures, are analysed using lattice Boltzmann method （LBM） simulations and are compared against experimental data from the literature.

Background: Documenting the entire lifetime of long-lived organisms requires splicing together short-term observations. Matrix demography provides a tool to calculate lifetime statistics, but large samples from juvenile to adult are needed, and few such studies have been done in tropical trees because high species diversity limits sample sizes. The 50-ha plot at Barro Colorado in Panama was designed to provide large samples, and with 30years of censuses, accurate population matrices can be ***: In 31 abundant species, I divided all individuals≥1 cm dbh into 4 or 5 size class in each of seven censuses. Movements of stems between size classes over two censuses are termed transitions, and I constructed complete transition matrices for each species. From the matrices, I derived analytic solutions for lifetime demographic statistics. Expected adult lifespan from the sapling stage was the key ***: Expected adult lifespan from the sapling stage varied 100-fold over the 31 species, from 0.5 to 50 years,and maturation time varied from 19 to nearly 200 years. Species with the highest growth rates also had high death rates, and theoretical calculations of reproductive lifespan show that the fast-growing pioneer species have short expected adult lifespans relative to the average slow-growing, shade-tolerant species. Within the slowgrowth category, however, there was high variation in expected adult lifespan, and several shade-tolerant species under-performed the pioneers in terms of adult ***: Analytical solutions from population matrices allow theoretical analyses that integrate short-term growth records into lifespans of tropical trees. The analyses suggest that pioneer species must reproduce more successfully than shade-tolerant species to persist in the Barro Colorado forest. My next goal is to incorporate seed production and germination into lifetime matrix demography to test this hypothesis.
