| 1 | Clinical characteristics and surgical treatment of schwannomas of the esophagus and stomach: A case series and systematic review显示文摘BACKGROUND Gastrointestinal schwannomas are slow-growing benign mesenchymal neoplasms that originate from Schwann cells of the nerve sheath of Auerbach′s plexus or less frequently from Meissner′s plexus.The main differential diagnosis of gastric schwannomas are the gastrointestinal stromal tumors(GISTs),which are classified by their immunohistochemistry.The treatment of choice for gastric schwannomas is surgery where laparoscopy plays an important role.Wedge resection,subtotal or total gastrectomy can be done.In its counterpart,esophageal schwannomas are benign tumors of the esophagus that are very uncommon since they comprise less than 2%of all esophageal tumors.The main differential diagnosis is the leiomyoma which corresponds to the most common benign esophageal tumor,followed by GIST.The treatment consists on tumoral enucleation or esophagectomy.AIM To review the available literature about gastrointestinal schwannomas;especially lesions from de stomach and esophagus,including diagnosis,treatment,and follow up,as well as,reporting our institutional experience.METHODS A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes guidelines.The following databases were used for reviewing process:Pub Med,Ovid,MEDLINE,and Scopus.Only English language manuscripts were included.All gastrointestinal schwannomas specifically located in the esophagus and stomach were included.Cases that did not report long-term follow-up were excluded.RESULTS Gastric localization showed a higher prevalence in both,the literature review and our institution:94.95%(n=317)and 83%(n=5)respectively.With a follow-up with disease-free survival greater than 36 mo in most cases:62.01%(n=80)vs66.66%(n=4).In both groups,the median size was>4.1 cm.Surgical treatment is curative in most cases CONCLUSION Schwannoma must be taken into account in the differential diagnosis of gastrointestinal mesenchymal tumors.It has a good prognosis,and most are benign.A disease-free survival of more than 36 mo can be achieved by surgery. | Jesús Morales-Maza Francisco Ulises Pastor-Sifuentes Germán E Sánchez-Morales Emilio Sanchez-Garcia Ramos Oscar Santes Uriel Clemente-Gutiérrez Adriana Simoneta Pimienta-Ibarra Heriberto Medina-Franco | 2019 | World Journal of Gastrointestinal Oncology2019，11，9： | 7 |
| 2 | Effectiveness of a microabrasion technique using 16% HCL with manual application on fluorotic teeth: A series of studies显示文摘BACKGROUND Dental fluorosis is caused by excessive fluoride ingestion during tooth formation.As a consequence,there is a higher porosity on the enamel surface,which causes an opaque look.AIM The aim of this study was to identify a dental intervention to improve the smile in patients with tooth fluorosis.Additional aims were to relate the stain size on fluorotic teeth with the effectiveness of stain removal,enamel loss and procedure time using a manual microabrasion technique with 16%hydrochloric acid(HCL).METHODS An experimental study was carried out on 84 fluorotic teeth in 57 adolescent patients,33 females and 24 males,with moderate to severe fluorosis.The means,standard deviations and percentages were analyzed using nonparametric statistics and ArchiCAD 15 software was used for the variables including stain size and effectiveness of stain removal.RESULTS The average enamel loss was 234μm and was significantly related to the procedure time categorized as 1-4 min and 4.01-6 min,resulting in a P>0.000.The microabrasion technique using 16%HCL was effective in 90.6%of patients and was applied manually on superficial stains in moderate and severe fluorosis.Procedure time was less than 6 min and enamel loss was within the acceptable range.CONCLUSION Microabrasion is a first-line treatment;however,the clinician should measure the average enamel loss to ensure that it is within the approximate range of 250μm in order to avoid restorative treatment. | Martina Nevárez-Rascón Nelly Molina-Frechero Edith Adame Ethel Almeida Uriel Soto-Barreras Enrique Gaona Alfredo Nevárez-Rascón | 2020 | World Journal of Clinical Cases2020，8，4： | 2 |

| 5 | Leaching kinetics in cyanide media of Ag contained in the industrial mining-metallurgical wastes in the state of Hidalgo, Mexico显示文摘The leaching kinetics in cyanide media of the silver contained in the Dos Carlos waste tailings at the City of Pachuca de Soto, Hidalgo State, Mexico were carried out. The used material contained the following chemical composition: 56 10-6of Ag, 0.6 10 6of Au and 70.43%(by weight) of SiO2; 7.032%(by weight) of Al2O3; 2.69%(by weight) of Fe; 0.46%(by weight) of Mn; 3.98%(by weight) of K2O; 3.34%(by weight) of CaO; 2.50%(by weight) of Na2O; 0.04%(by weight) of Zn; 0.026%(by weight) of Pb. The mineralogical phases present were the following: Silica, albite, argentite, berlinite, orthoclase, potassium jarosite, and natrojarosite. In the leaching kinetics in cyanide media, and under the studied conditions,the effect of the CN concentration on the reaction rate has no effect on the whole process of alkaline cyanidation, of which the reaction order is n 0. Temperature has an effect on the cyanidation rate of the reaction, with an activation energy of 47.9 KJ/mol. At the same time, when the particle size decreases there is an increase in the reaction rate, which is inversely proportional to the particle diameter; when increasing the NaOH concentration there is an increase in the reaction rate Kexp, with a reaction order(n) of 0.215 under the studied ranges. | Juan Hernandez Francisco Patino Isauro Rivera Iván Alejandro Reyes Misrael Uriel Flores Julio Cesar Juarez Martín Reyes | 2014 | International Journal of Mining Science and Technology2014，24，5： | 1 |

| 15 | A nitrogen index for improving nutrient management within commercial Mexican dairy operations显示文摘Some intensive dairy operations in Mexico are contributing to large,negative environmental impacts,especially in regions dominated by high concentrations of animals.Excessive manure inputs plus additional nitrogen(N)fertilizer has,in some cases,resulted in background nitrate–nitrogen(NO3–N)levels in irrigation water that are so high,it is not safe for human consumption.One reason is that commercial farmers in this region are currently not using any method to rapidly calculate N budgets based on their practices,N inputs and/or crop N uptake.The Nitrogen Index,a quick tool that can be used to conduct an assessment within a few minutes,was developed for Mexico,but needed further testing under commercial field operations.We conducted studies in 2010 and 2011 and collected soil and crop information from several commercial farming operations to test the tool.The index accurately assessed(Po0.0001)residual soil nitrate after harvesting corn(Zea mays L.)and oats(Avena sativa L.);and also accurately assessed the N uptake of these crops(Po0.01).The Mexico N Index is a tool that can be used to quickly conduct N balances,show when N is being over-applied,and help reduce over-application,thus reducing N losses to the environment and improving management of dairy forage systems in Mexico. | Uriel Figueroa-Viramontes Jorge A.Delgado Juan I.Sánchez-Duarte Esmeralda Ochoa-Martínez Gregorio Núñez-Hernández | 2016 | International Soil and Water Conservation Research2016，4，1： | 0 |
| 16 | Higher cardiovascular risk scores and liver fibrosis risk estimated by biomarkers in patients with metabolic-dysfunction-associated fatty liver disease显示文摘BACKGROUND The definition of metabolic-dysfunction-associated fatty liver disease(MAFLD)allows identification of metabolically complicated patients.Fibrosis risk scores are related to cardiovascular risk(CVR)scores and could be useful for the identification of patients at risk of systemic complications.AIM To evaluate the relationship between MAFLD and CVR using the Framingham risk score in a group of Mexican patients.METHODS Cross-sectional,observational and descriptive study carried out in a cohort of 585 volunteers in the state of Veracruz with MAFLD criteria.The risk of liver fibrosis was calculated with aspartate aminotransferase-to-platelet ratio index,nonalcoholic fatty liver disease score and fibrosis-4,as well as with transient hepatic elastography with Fibroscan~?.The CVR was determined by the Framingham system.RESULTS One hundred and twenty-five participants(21.4%)with MAFLD criteria were evaluated,average age 54.4 years,63.2%were women,body mass index 32.3 kg/m~2.The Framingham CVR was high in 43 patients(33.9%).Transient elastography was performed in 55.2%of volunteers;39.1%with high CVR and predominance in advanced fibrosis(F3–F4).The logistic regression analysis showed that liver fibrosis,diabetes and hypertension independently increased CVR.CONCLUSION One of every three patients with MAFLD had a high CVR,and in those with high fibrosis risk,the CVR risk was even greater. | Giovanni Alejandro Salgado Alvarez Samanta Mayanin Pinto Galvez Uriel Garcia Mora Ana Delfina Cano Contreras Cristina Durán Rosas Bryan Adrián Priego-Parra Arturo Triana Romero Mercedes Amieva Balmori Federico Roesch Dietlen Sophia Eugenia Martinez Vazquez Ines Osvely Mendez Guerrero Luis Alberto Chi-Cervera Raúl Bernal Reyes Leonardo Alberto Martinez Roriguez Maria Eugenia Icaza Chavez Jose Maria Remes Troche | 2022 | World Journal of Hepatology2022，14，8： | 0 |
