1Impact of co-infections with enteric pathogens on children suffering from acute diarrhea in southwest China显示文摘Background:Acute diarrhea is a global health problem,resulting in high morbidity and mortality in children.It has been suggested that enteric pathogen co-infections play an important role in gastroenteritis,but most research efforts have only focused on a small range of species belonging to a few pathogen groups.This study aimed to assess the impact of co-infections with a broad range of enteric pathogens on children aged below five years who suffer from acute diarrhea in southwest China.Method:A total of 1020 subjects(850 diarrhea cases and 170 healthy controls)were selected from four sentinel hospitals in Kunming,Yunnan province,southwest China,from June 2014 to July 2015.Stool specimens were collected to detect five virus(rotavirus group A,RVA;norovirus,NoV;Sapovirus,SaV;astrovirus,As;and adenovirus,Ad),seven bacterial(diarrheagenic Escherichia coli,DEC;non-typhoidal Salmonella,NTS;Shigella spp.;Vibrio cholera;Vibrio parahaemolyticus;Aeromonas spp.;and Plesiomonas spp.),and three protozoan(Cryptosporidium spp.,Giardia lamblia,and Blastocystis hominis,B.hominis)species using standard microbiologic and molecular methods.Data were analyzed using the partial least square regression technique and chi-square test.Results:At least one enteric pathogen was detected in 46.7%(n=397)of acute gastroenteritis cases and 13.5%(n=23)of healthy controls(χ^(2)=64.4,P<0.05).Single infection with RVA was associated with acute diarrhea(26.5%vs.5.8%,P<0.05).The prevalence of a single infection with B.hominis in diarrhea cases was higher than in healthy controls(3.1%vs.0.5%,OR=4.7,95%CI:1.01–112.0).Single infection with NoV GII was not associated with diarrhea(4.4%vs.3.5%,OR=1.2,95%CI:0.5–3.3).Single infections with bacterial species were not observed.The prevalence of co-infections with two enteric pathogens in diarrhea cases was higher than in asymptomatic children(20.1%vs.5.3%,P<0.05).RVA-NoV GII was the most common co-infection in symptomatic children(4.4%),with it aggravating the severity of diarrhea.Conclusions:Although it is clear that RVA has an overwhelming impact on diarrhea illnesses in children,co-infection with other enteric pathogens appears to also aggravate diarrhea severity.These findings should serve as evidence for public health services when planning and developing intervention programs.Shun-Xian Zhang Yong-Ming Zhou Wen Xu Li-Guang Tian Jia-Xu Chen Shao-Hong Chen Zhi-Sheng Dang Wen-Peng Gu Jian-Wen Yin Emmanuel Serrano Xiao-Nong Zhou 2016Infectious Diseases of Poverty2016,5,1:19
2Bone-conditioned medium contributes to initiation and progression of osteogenesis by exhibiting synergistic TGF-β1/BMP-2 activity显示文摘Guided bone regeneration (GBR) often utilizes a combination of autologous bone grafts, deproteinized bovine bone mineral(DBBM), and collagen membranes. DBBM and collagen membranes pre-coated with bone-conditioned medium (BCM) extracted from locally harvested autologous bone chips have shown great regenerative potential in GBR. However, the underlying molecular mechanism remains largely unknown. Here, we investigated the composition of BCM and its activity on the osteogenic potential of mesenchymal stromal cells. We detected a fast and significant (P <0.001) release of transforming growth factor-β1 (TGF-β1) from autologous bone within 10 min versus a delayed bone morphogenetic protein-2 (BMP-2) release from 40 min onwards. BCMs harvested within short time periods (10, 20, or 40 min), corresponding to the time of a typical surgical procedure, significantly increased the proliferative activity and collagen matrix production of BCM-treated cells. Long-term (1, 3, or 6 days)-extracted BCMs promoted the later stages of osteoblast differentiation and maturation. Short-term-extracted BCMs, in which TGF-β1 but no BMP-2was detected, reduced the expression of the late differentiation marker osteocalcin. However, when both growth factors were present simultaneously in the BCM, no inhibitory effects on osteoblast differentiation were observed, suggesting a synergistic TGF-β1/BMP-2 activity. Consequently, in cells that were co-stimulated with recombinant TGF-β1 and BMP-2, we showed a significant stimulatory and dose-dependent effect of TGF-β1 on BMP-2-induced osteoblast differentiation due to prolonged BMP signaling and reduced expression of the BMP-2 antagonist noggin. Altogether, our data provide new insights into the molecular mechanisms underlying the favorable outcome from GBR procedures using BCM, derived from autologous bone grafts.Maria B.Asparuhova Jordi Caballé-Serrano Daniel Buser Vivianne Chappuis 2018International Journal of Oral Science2018,10,4:17
3Non-invasive diagnosis of gastric mucosal atrophy in an asymptomatic population with high prevalence of gastric cancer显示文摘AIM: To validate a non-invasive method to detect gastric mucosal atrophy in a Chilean population with high prevalence of gastric cancer and a poor survival rate. METHODS: We first determined the optimal cut-off level of serum pepsinogen (PG)-1, PG-1/PG-2 ratio and 17-gastrin in 31 voluntary symptomatic patients (mean age: 66.1 years), of them 61% had histologically confirmed gastric atrophy. Then, in a population-based sample of 536 healthy individuals (209 residents in counties with higher relative risk and 327 residents in counties with lower relative risk for gastric cancer), we measured serum anti-H pylori antibodies, PG and 17-gastrin and estimated their risk of gastric cancer. RESULTS: We found that serum PG-1 < 61.5 μg/L, PG-1/PG-2 ratio < 2.2 and 17-gastrin > 13.3 pmol/L had a high specificity (91%-100%) and a fair sensitivity (56%-78%) to detect corpus-predominant atrophy. Based on low serum PG-1 and PG-1/PG-2 ratio together as diagnostic criteria, 12.5% of the asymptomatic subjects had corpus-predominant atrophy (0% of those under 25 years and 20.2% over 65 years old). The frequency of gastric atrophy was similar (12% vs 13%) but H pylori infection rate was slightly higher (77% vs 71%) in the high-risk compared to the low-risk counties. Based on their estimated gastric cancer risk, individuals were classified as: low-risk group (no H pylori infection and no atrophy; n = 115; 21.4%); moderate-risk group(H pylori infection but no atrophy; n = 354, 66.0%); and high-risk group (gastric atrophy, with or without H pylori infection; n = 67, 12.5%). The high-risk group was significantly older (mean age: 61.9 ± 13.3 years), more frequently men and less educated as compared with the low-risk group. CONCLUSION: We propose to concentrate on an upper gastrointestinal endoscopy for detection of early gastric cancer in the high-risk group. This intervention model could improve the poor prognosis of gastric cancer in Chile.Antonio Rollan Catterina Ferreccio Alessandra Gederlini Carolina Serrano Javiera Torres Paul Harris 2006World Journal of Gastroenterology2006,12,44:14
4How important is donor age in liver transplantation?显示文摘The age of liver donors has been increasing in the past several years because of a donor shortage. In the United States, 33% of donors are age 50 years or older, as are more than 50% in some European countries. The impact of donor age on liver transplantation(LT) has been analyzed in several studies with contradictory conclusions. Nevertheless, recent analyses of the largest databases demonstrate that having an older donor is a risk factor for graft failure. Donor age is included as a risk factor in the more relevant graft survival scores, such as the Donor Risk Index, donor age and Model for End-stage Liver Disease, Survival Outcomes Following Liver Transplantation, and the Balance of Risk. The use of old donors is related to an increased rate of biliary complications and hepatitis C virus-related graft failure. Although liver function does not seem to be significantly affected by age, the incidence of several liver diseases increases with age, and the capacity of the liver to manage or overcome liver diseases or external injuries decreases. In this paper, the importance of age in LT outcomes, the role of donor age as a risk factor, and the influence of aging on liver regeneration are reviewed.Alberto Lué Estela Solanas Pedro Baptista Sara Lorente Juan J Araiz Agustin Garcia-Gil M Trinidad Serrano 2016World Journal of Gastroenterology2016,22,21:10
5Geological applications using geospatial standards-an example from OneGeology-Europe and GeoSciML显示文摘The Geoscience Markup Language(GeoSciML)has been developed to enable the interchange of geoscience information,principally that portrayed on geological maps as well as boreholes.A GeoSciML testbed was developed both to test the implementation of the data model and its application in web services.The OneGeology-Europe project aims to use the GeoSciML data model,and build on the experience of the GeoSciML testbed,in implementing a geoportal for a harmonised geological map of Europe at 1:1 million scale.This involves the integration of web services from 20 participating organisations.An important objective of OneGeology-Europe is to contribute to Infrastructure for Spatial Information in the European Community(INSPIRE),both through the development of a geological data specification and the use of the INSPIRE technical architecture.GeoSciML and the OneGeology-Europe project are also steps towards incorporating geoscience data into a Digital Earth.Both the development of GeoSciML and the implementation of web services for GeoSciML and OneGeology-Europe,have followed a standards-based metho-dology.The technical architecture comprises a geoportal providing access to a Catalogue Service for the Web for metadata describing both the data and services available.OneGeology-Europe will provide bothWeb Map Services view andWeb Feature Services download services,which aim to be compliant with the INSPIRE implementing rules.John Laxton Jean-Jacques Serrano Agnes Tellez-Arenas 2010International Journal of Digital Earth2010,3,S01:9

7Antibiotic resistance and molecular characterization of diarrheagenic Escherichia coli and non-typhoidal Salmonella strains isolated from infections in Southwest China显示文摘Background:Bacterial diarrhea is one of the most common causes for medical consultations,mortality and morbidity in the world.Diarrheagenic Escherichia coli(DEC)and non-typhoidal Salmonella(NTS)are major intestinal pathogens in developing countries,and the indiscriminate use of antibiotics has greatly contributed to resistant strains.Hence,the aim of the present study is to identify the antimicrobial resistance patterns and the molecular characteristics of DEC and NTS in southwest,China.Methods:1121 diarrheal patients and 319 non-diarrheal subjects across all age groups were recruited from four sentinel hospitals from June 2014 to July 2015 in Kunming City,Yunnan Province.Each stool specimen was collected to detect DEC and NTS with standard microbiological and molecular methods.Antimicrobial resistance testing was performed with the Kirby-Bauer disk diffusion method,and the standards for antimicrobial susceptibility testing complied with the Clinical and Laboratory Standards Institute(CLSI).Molecular characterization of strains was carried out using pulsed-field gel electrophoresis(PFGE).A structured questionnaire was used to record basic epidemiological data(e.g.sex,age,residence,season,etc.).Data were analyzed using Chi-square or Fisher’s exact test.Results:DEC was detected in 127(11.33%)diarrhea cases and 9(2.82%)non-diarrheal cases(χ^(2)=20.69,P<0.001,OR=4.36,95%CI:2.19-8.65),and the prevalence of NTS isolated from diarrhea cases was higher than that of non-diarrheal cases across all age groups(n=42,3.75%,n=1,0.31%,χ^(2)=10.10,P=0.002,OR=12.38,95%CI:1.70-90.29).The rates of resistance to ten antibiotics of DEC and NTS showed significant differences(χ^(2)=386.77,P<0.001;χ^(2)=191.16,P<0.001).The rates of resistance to Amoxicillin and Clavulafiate(AMC),Cephalothin(CEP),Gentamicin(GEN)and Sulfamethoxazole-Trimethoprim(SXT)of DEC isolated from diarrhea cases were higher than those of NTS isolated from diarrhea patients(37.01%vs 14.29%,χ^(2)=7.57,P=0.006;29.92%vs 11.90%,χ^(2)=5.40,P=0.02;37.01%vs 11.90%,χ^(2)=5.80,P=0.016;62.20%vs 26.19%,χ^(2)=16.44,P<0.001;respectively).Ciprofloxacin(CIP)was the most sensitive antibiotic for DEC and NTS strains isolated from diarrhea cases.Resistance rates of DEC isolates from cases and controls to more than three kinds antimicrobials(multidrug resistance,MDR)showed no significant differences(81.10%vs 88.89%,P=0.33).Pulsotype patterns of DEC strains were highly diverse;however,the pulsotype pattern of NTS strains was closely related to the serotype.The pattern of S.enteritidis was highly similar,but the S.enterica Typhimurium strain was discrete.Conclusions:Antibiotic resistance of Enterobacteriaceae is of great concern.The societal effects of antibiotic use justify strict monitoring to combat increases in antimicrobial resistance.Molecular epidemiology and systematic epidemiological investigation can provide accurate evidence for tracking the infection source.Shun-Xian Zhang Yong-Ming Zhou Li-Guang Tian Jia-Xu Chen Rita Tinoco-Torres Emmanuel Serrano Shi-Zhu Li Shao-Hong Chen Lin Ai Jun-Hu Chen Shang Xia Yan Lu Shan Lv Xue-Jiao Teng Wen Xu Wen-Peng Gu Si-Tang Gong Xiao-Nong Zhou Lan-Lan Geng Wei Hu 2018Infectious Diseases of Poverty2018,7,1:7

9Excretion of biliary compounds during intrauterine life显示文摘In adults,the hepatobiliary system,together with the kidney,constitute the main routes for the elimination of several endogenous and xenobiotic compounds into bile and urine,respectively.However,during intrauterine life the biliary route of excretion for cholephilic compounds,such as bile acids and biliary pigments,is very poor.Although very early in pregnancy the fetal liver produces bile acids,bilirubin and biliverdin,these compounds cannot be efficiently eliminated by the fetal hepatobiliary system,owing to the immaturity of the excretory machinery in the fetal liver.Therefore,the potentially harmful accumulation of cholephilic compounds in the fetus is prevented by their elimination across the placenta.Owing to the presence of detoxifying enzymes and specifi c transport systems at different locations of the placental barrier,such as the endothe-lial cells of chorionic vessels and trophoblast cells,this organ plays an important role in the hepatobiliary-like function during intrauterine life.The relevance of this excretory function in normal fetal physiology is evident in situations where high concentrations of biliary compounds are accumulated in the mother.This may result in oxidative stress and apoptosis,mainly in the placenta and fetal liver,which might affect normal fetal development and challenge the fate of the pregnancy.The present article reviews current knowledge of the mechanisms underlying the hepatobiliary function of the fetal-placental unit and the repercussions of several pathological conditions on this tandem.Rocio IR Macias Jose JG Marin Maria A Serrano 2009World Journal of Gastroenterology2009,15,7:6
10Liver transplantation and the management of progressive familial intrahepatic cholestasis in children显示文摘Progressive familial intrahepatic cholestasis(PFIC) is a constellation of inherited disorders that result in the impairment of bile flow through the liver that predominantly affects children. The accumulation of bile results in progressive liver damage, and if left untreated leads to end stage liver disease and death. Patients often present with worsening jaundice and pruritis within the first few years of life. Many of these patients will progress to end stage liver disease and require liver transplantation. The role and timing of liver transplantation still remains debated especially in the management of PFIC1. In those patients who are appropriately selected, liver transplantation offers an excellent survival benefit. Appropriate timing and selection of patients for liver transplantation will be discussed, and the short and long term management of patients post liver transplantation will also be described.Ashley Mehl Humberto Bohorquez Maria-Stella Serrano Gretchen Galliano Trevor W Reichman 2016World Journal of Transplantation2016,6,2:6
11Conversion from calcineurin inhibitors to mTOR inhibitors stabilizes diabetic and hypertensive nephropathy after liver transplant显示文摘AIM: To investigate if conversion to the mammalian target of rapamycin inhibitors(mTORi) improves renal function in diabetic and/or hypertensive liver transplant patients immunosuppressed with tacrolimus or cyclosporine.METHODS: The study included 86 liver graft recipients immunosuppressed with mTORi treatment after orthotopic liver transplantation(OLT), including all liver recipients with worsening renal function before conversion to mTORi(n = 55 patients) and recipients with normal renal function who converted to m TORi for other reasons(n = 31 patients). We identified patients with diabetes mellitus(n = 28), arterial hypertension(n = 27), proteinuria(n = 27) and all three factors(n = 8)(some patients have hypertension and diabetes and no proteinuria). The primary endpoint was evolution in renal function defined as the development in plasma creatinine as a function of diabetes mellitus(DM), hypertension(HT) or proteinuria. We required elevated serum creatinine for at least two weeks to define renal dysfunction.RESULTS: Only patients that converted because of renal failure with plasma creatinine levels > 1.5 mg/dL showed an improvement of renal function(2.14 to 1.77 mg/dL)(P = 0.02). Patients with DM showed no improvement of serum creatinine levels(1.31 mg/dL to 1.37 mg/dL) compared with non DM patients(1.31 mg/dL to 1.15 mg/dL)(P = 0.01), HT patients(1.48 mg/dL to 1.5 mg/dL) with non HT patients(1.21mg/d L to 1.08 mg/dL) and patients with proteinuria(1.44 mg/dL to 1.41 mg/dL) and no proteinuria(1.31 mg/dL to 1.11 mg/dL). CONCLUSION: In OLT recipients with diabetes or hypertensive nephropathy, conversion to m TORi does not improve renal function but stabilizes plasma levels of creatinine. Proteinuria is not a contraindication to conversion to m TORi; it also stabilizes renal function. Conversion to m TORi should only be avoided in patients with diabetes, hypertension and proteinuria.José M álamo Claudia Olivares Lydia Barrera Luis M Marín Gonzalo Suarez Carmen Bernal Juan Serrano Jordi Muntané Francisco J Padillo Miguel A Gómez 2015World Journal of Transplantation2015,5,1:6
12Micro- and nanoporous materials capable of absorbing solvents and oils reversibly: the state of the art显示文摘Treatment of petroleum spills and organic solvent pollution in general is an important issue; several techniques are under development to remove oil from water. The use of absorbents is one of the most common techniques to tackle this problem. These absorbents can be classified based on their characteristics of recyclability into irreversible and reversible ones. In this review, we discuss the application of several materials as oil absorbents,according to their classification and characteristics such as hydrophobicity, surface area and oil absorption capacity.Also, the fabrication methods for some materials are presented and analyzed.Javier S.

15Land cover changes and fragmentation in mountain neotropical ecosystems of Oaxaca, Mexico under community forest management显示文摘Changes in land cover have a direct impact on forest ecosystem goods and services. In this study, changes in land cover in Sierra de Juarez–Oaxaca ecosystems were estimated using a consistent processing of Landsat images and OBIA methodology. Additionally, landscape analyses using FRAGSTAT were conducted. In 2014, Sierra de Juarez–Oaxaca was covered by approximately 84% of forests, mainly pine-oak and cloud forests. After extensive deforestation until 2001, this trend was reversed and the forest cover surface area in 2014 was slightly higher than in 1979. The comparison of the landscape structure of the forested and agricultural lands suggests an increase in habitat heterogeneity. However, interspersion and juxtaposition indices, showing the patch shape by patch area and perimeter, were similar throughout the study period(1979–2014). Social and economic drivers can explain this situation: namely, community organization, forest enterprises, payment for ecosystem services programs, and changes of agricultural activity. Communities in the Sierra of Oaxaca have reforested degraded lands, created community forest enterprises, and preserved the forest under conservation schemes like those proposed by the Mexican payment for ecosystem services programs. However, their sustainable management faces internal challenges and has become highly dependent on political and institutional decisions beyond their control.Rafael M~a Navarro Cerrillo Dennis J.Esteves Vieira Susana Ochoa-Gaona Bernardus H.J.de Jong M~a del Mar Delgado Serrano 2019Journal of Forestry Research2019,30,1:4

20Molecular aspects of mammalian fertilization显示文摘Mammalian fertilization is a highly regulated process, much of which are not clearly understood. Here we present some information in order to elaborate a working hypothesis for this process, beginning with the sperm modifications in the epidydimis up to sperm and egg plasmalemma interaction and fusion. We also discuss the still poorly understood capacitation process, the phenomenon of sperm chemo-attraction that brings the capacitated sperm to interact with the oocyte vestments and certain aspects of the acrosome reaction.Hector Serrano Dolores Garcia-Suarez 2001Asian Journal of Andrology2001,3,4:3
