| 2 | New approaches for evaluation of soil health, sensitivity and resistance to degradation显示文摘Assessment of soil health requires complexevaluation of properties and functions responsible for abroad range of ecosystem services. Numerous soil qualityindices (SQI) have been suggested for the evaluation ofspecific groups of soil functions, but comparison of variousSQI is impossible because they are based on a combinationof specific soil properties. To avoid this problem, wesuggest an SQI-area approach based on the comparison ofthe areas on a radar diagram of a combination of chemical,biological and physical properties. The new approach isindependent of the SQI principle and allows rapid andsimple comparison of parameter groups and soils. Anotherapproach analyzing the resistance and sensitivity ofproperties to degradation is suggested for a detailedevaluation of soil health. The resistance and sensitivityof soil properties are determined through comparison withthe decrease of soil organic carbon (SOC) as a universalparameter responsible for many functions. The SQI-areaand resistance/sensitivity approaches were tested based on quences after the ab and on ment of agricultural soils. Both the SQI-area and the resistance/sensitivity approaches areuseful for basic and applied research, and for decisionmakersto evaluate land-use practices and measure thedegree of soil degradation. | Yakov KUZYAKOV Anna GUNINA Kazem ZAMANIAN Jing TIAN Yu LUO Xingliang XU Anna YUDINA Humberto APONTE Hattan ALHARBI Lilit OVSEPYAN Irina KURGANOVA Tida GE Thomas GUILLAUME | 2020 | Frontiers of Agricultural Science and Engineering2020，7，3： | 6 |
| 3 | Plastid genome sequences of legumes reveal parallel inversions and multiple losses of rps16 in papilionoids显示文摘迄今为止,荚的公开可得到的质体染色体通常被限制了到亚科 Papilionoideae。这里,我们报导跨越所有三个亚科的荚的 13 个新质体染色体。代表 Caesalpinioideae 和 Mimosoideae 的染色体高度在基因内容和基因顺序被保存,类似于祖先的被子植物染色体组织。然而,在 Papilionoideae 以内的染色体首先在大单个拷贝区域在九个 intergenic 分隔符由于删除减少了尺寸。我们的学习也显示 rps16 独立地在荚被失去了至少五次,与在 papilionoids 之中散布的另外的基因和 intron 损失。另外,从在 papilionoids, Lupinus 和 Robinia 以内的二个不同的系的类,分别地有 36 和 39 kb 的平行倒置。当它看起来被 29 bp 重复在二 trnS 基因以内引起,这平行倒置是新奇的。这次重复在显示为在更多的种类在场的这倒置有潜力的所有可得到的荚质体染色体是在场的。homoplasious 倒置的这个案例也是一些倒置事件不能是可靠种系发生的标记的证据。 | Erika N.

| 4 | Complications and survival in patients undergoing colonic stenting for malignant obstruction显示文摘AIM:To investigate whether predicting patients that might be at a higher risk for complications might serve to improve the selection of patients undergoing colonic stenting.METHODS:A retrospective review of consecutive patients who underwent an attempted self-expandable metal stent(SEMS)insertion for malignant colonic obstruction between November 2006 and March 2013.All patients were either referred for preoperative colonic decompression with the intent of a single surgical procedure,or for palliation of the malignant colorectal obstruction for unresectable cancer.Fisher’s test orχ2test was performed on categorical variables,and the t test for continuous variables.Univariable and multivariable logistic regression were used to examine the association between independent variables and the presence of complications from SEMS insertion.RESULTS:SEMS insertion was attempted in 73 patients.Males comprised 55.71%and the mean age was 67.41±12.41 years.Of these,65.15%underwent subsequent surgery,while 34.85%received SEMS as palliation for advanced disease.Extracolonic tumors were only4.76%.The majority of patients had stageⅣdisease(63.83%),while the remainder had stageⅢ(36.17%).SEMS were successfully inserted in 93.85%(95%CI:87.85%-99.85%).Perforations occurred in 4.10%,SEMS migration in 8.21%,and stent re-occlusion from ingrowth occurred in 2.74%of patients.The mean duration of follow up for the patients was 13.52±17.48 mo(range 0-73 mo).None of the variables:age,sex,time between the onset of symptoms to SEMS insertion,time between SEMS insertion and surgery,length of the stenosis,location of the stenosis,albumin level,or receiving neoadjuvant chemotherapy,could predict the development of complications from either SEMS insertion nor prolonged survival.CONCLUSION:None of the variables could predict the development of complications or survival.Further studies are required to identify patients who would benefit the most from SEMS. | Majid A Almadi Nahla Azzam Othman Alharbi Alabbas H Mohammed Nazia Sadaf Abdulrahman M Aljebreen | 2013 | World Journal of Gastroenterology2013，19，41： | 5 |
| 5 | Use of testicular sperm in couples with SCSA-defined high sperm DNA fragmentation and failed intracytoplasmic sperm injection using ejaculated sperm显示文摘Sperm DNA fragmentation(SDF)has been linked with male infertility,and previous studies suggest that SDF can have negative influence on pregnancy outcomes with assisted reproduction.We performed a retrospective review of consecutive couples with a high SDF level that had intracytoplasmic sperm injection(ICSI)using testicular sperm(T-ICSI).We compared the T-ICSI outcomes to that of two control groups:87 couples with failed first ICSI cycle and who had a second ICSI cycle using ejaculated sperm(Ej-ICSI),and 48 consecutive couples with high sperm chromatin structure assay(SCSA)-defined SDF(>15%)that underwent an ICSI cycle using ejaculated sperm after one or more failed ICSI cycles(Ej-ICSI-high SDF).The mean number of oocytes that were retrieved and the total number of embryos were not different among the three groups.The mean number of transferred embryos in the T-ICSI group was higher than the Ej-ICSI group but not significantly different than the Ej-ICSI-high SDF group(1.4,1.2,and 1.3,respectively,P<0.05).Clinical pregnancy rate in the T-ICSI group was not significantly different than the Ej-ICSI and Ej-ICSI-high SDF groups(48.6%,48.2%,and 38.7%,respectively,P>0.05).No significant difference was found in live birth rate when comparing T-ICSI to Ej-ICSI and Ej-ICSI-high SDF groups.The results suggest that pregnancy outcomes and live birth rates with T-ICSI are not significantly superior to Ej-ICSI in patients with an elevated SCSA-defined sperm DNA fragmentation and prior ICSI failure(s). | Mohannad Alharbi Fadl Hamouche Simon Phillips Jacques Isaac Kadoch Armand Zini | 2020 | Asian Journal of Andrology2020，22，4： | 4 |
| 6 | Tuberculous esophagomediastinal fistula with concomitant mediastinal bronchial artery aneurysm-acute upper gastrointestinal bleeding: A case report显示文摘BACKGROUND Esophagomediastinal fistula is a very rare complication of tuberculosis in otherwise healthy adults, and mediastinal bronchial artery aneurysm is even rarer. In this case report, we describe a rare case of tuberculosis complication that presented with acute upper gastrointestinal(GI) bleeding. It also highlights the benefits of chest computed tomography(CT) as an excellent adjunct diagnostic tool to endoscopy and bronchoscopy and the role of trans-arterial embolization as a minimal invasive therapy alternative to surgery.CASE SUMMARY A 19-year-old medically free male patient presented with acute multiple episodes of hematemesis for 1 d. Upper GI endoscopy, bronchoscopy, and chest CT with IV contrast confirmed esophagomediastinal fistula with mediastinal bronchial artery aneurysm. After resuscitating patient with IV fluid and blood product transfusion, trans catheter embolization was performed for mediastinal bronchial artery aneurysm.CONCLUSION We successfully treated a patient with acute upper GI bleeding due to tuberculous esophagomediastinal fistula and mediastinal bronchial artery aneurysm using transcatheter coil embolization. | Sultan R Alharbi | 2019 | World Journal of Gastroenterology2019，25，17： | 4 |
| 7 | An efficient descriptor model for designing materials for solar cells显示文摘An efficient descriptor model for fast screening of potential materials for solar cell applications is presented.It works for both excitonic and non-excitonic solar cells materials,and in addition to the energy gap it includes the absorption spectrum(α(E))of the material.The charge transport properties of the explored materials are modelled using the characteristic diffusion length(Ld)determined for the respective family of compounds.The presented model surpasses the widely used Scharber model developed for bulk heterojunction solar cells.Using published experimental data,we show that the presented model is more accurate in predicting the achievable efficiencies.To model both excitonic and non-excitonic systems,two different sets of parameters are used to account for the different modes of operation.The analysis of the presented descriptor model clearly shows the benefit of includingα(E)and Ld in view of improved screening results. | Fahhad H Alharbi Sergey N Rashkeev Fedwa El-Mellouhi Hans P Lüthi Nouar Tabet Sabre Kais | 2015 | npj Computational Materials2015，，1： | 3 |
| 8 | Clinical epidemiology of ulcerative colitis in Arabs based on the Montréal classification显示文摘AIM:To determine the clinical,epidemiological and phenotypic characteristics of ulcerative colitis(UC)in Saudi Arabia by studying the largest cohort of Arab UC patients.METHODS:Data from UC patients attending gastroenterology clinics in four tertiary care centers in three cities between September 2009 and September 2013were entered into a validated web-based registry,inflammatory bowel disease information system(IBDIS).The IBDIS database covers numerous aspects of inflammatory bowel disease.Patient characteristics,disease phenotype and behavior,age at diagnosis,course of the disease,and extraintestinal manifestations were recorded.RESULTS:Among 394 UC patients,males comprised51.0%and females 49.0%.According to the Montréal classification of age,the major chunk of our patients belonged to the A2 category for age of diagnosis at17-40 years(68.4%),while 24.2%belonged to the A3category for age of diagnosis at>40 years.According to the same classification,a majority of patients had extensive UC(42.7%),35.3%had left-sided colitis and29.2%had only proctitis.Moreover,51.3%were in remission,16.6%had mild UC,23.4%had moderate UC and 8.6%had severe UC.Frequent relapse occurred in17.4%patients,infrequent relapse in 77%and 4.8%had chronic disease.A majority(85.2%)of patients was steroid responsive.With regard to extraintestinal manifestations,arthritis was present in 16.4%,osteopenia in 31.4%,osteoporosis in 17.1%and cutaneous involvement in 7.0%.CONCLUSION:The majority of UC cases were young people(17-40 years),with a male preponderance.While the disease course was found to be similar to that reported in Western countries,more similarities were found with Asian countries with regards to the extent of the disease and response to steroid therapy. | Othman R Alharbi Nahla A Azzam Ahmed S Almalki Majid A Almadi Khalid A Alswat Nazia Sadaf Abdulrahman M Aljebreen | 2014 | World Journal of Gastroenterology2014，20，46： | 2 |
| 9 | An Intelligent Fine-Tuned Forecasting Technique for Covid-19 Prediction Using Neuralprophet Model显示文摘COVID-19,being the virus of fear and anxiety,is one of the most recent and emergent of various respiratory disorders.It is similar to the MERS-COV and SARS-COV,the viruses that affected a large population of different countries in the year 2012 and 2002,respectively.Various standard models have been used for COVID-19 epidemic prediction but they suffered from low accuracy due to lesser data availability and a high level of uncertainty.The proposed approach used a machine learning-based time-series Facebook NeuralProphet model for prediction of the number of death as well as confirmed cases and compared it with Poisson Distribution,and Random Forest Model.The analysis upon dataset has been performed considering the time duration from January 1st 2020 to16th July 2021.The model has been developed to obtain the forecast values till September 2021.This study aimed to determine the pandemic prediction of COVID-19 in the second wave of coronavirus in India using the latest Time-Series model to observe and predict the coronavirus pandemic situation across the country.In India,the cases are rapidly increasing day-by-day since mid of Feb 2021.The prediction of death rate using the proposed model has a good ability to forecast the COVID-19 dataset essentially in the second wave.To empower the prediction for future validation,the proposed model works effectively. | Savita Khurana Gaurav Sharma Neha Miglani Aman Singh Abdullah Alharbi Wael Alosaimi Hashem Alyami Nitin Goyal | 2022 | Computers, Materials & Continua2022，，4： | 2 |
| 10 | Leucine-rich repeat-containing G protein-coupled receptor 5 marks different cancer stem cell compartments in human Caco-2 and LoVo colon cancer lines显示文摘BACKGROUND Colon cancer cell lines are widely used for research and for the screening of drugs that specifically target the stem cell compartment of colon cancers.It was reported that colon cancer carcinoma specimens contain a subset of leucine-rich repeatcontaining G protein-coupled receptor 5(LGR5)-expressing stem cells,these socalled“tumour-initiating”cells,reminiscent in their properties of the normal intestinal stem cells(ISCs),may explain the apparent heterogeneity of colon cancer cell lines.Also,colon cancer is initiated by aberrant Wnt signaling in ISCs known to express high levels of LGR5.Furthermore,in vivo reports demonstrate the clonal expansion of intestinal adenomas from a single LGR5-expressing cell.AIM To investigate whether colon cancer cell lines contain cancer stem cells and to characterize these putative cancer stem cells.METHODS A portable fluorescent reporter construct based on a conserved fragment of the LGR5 promoter was used to isolate the cell compartments expressing different levels of LGR5 in two widely used colon cancer cell lines(Caco-2 and LoVo).These cells were then characterized according to their proliferation capacity,gene expression signatures of ISC markers,and their tumorigenic properties in vivo and in vitro.RESULTS The data revealed that the LGR5 reporter can be used to identify and isolate a classical intestinal crypt stem cell-like population from the Caco-2,but not from the LoVo,cell lines,in which the cancer stem cell population is more akin to B lymphoma Moloney murine leukemia virus insertion region 1 homolog(+4 crypt)stem cells.This sub-population within Caco-2 cells exhibits an intestinal cancer stem cell gene expression signature and can both self-renew and generate differentiated LGR5 negative progeny.Our data also show that cells expressing high levels of LGR5/enhanced yellow fluorescent protein(EYFP)from this cell line exhibit tumorigenic-like properties in vivo and in vitro.In contrast,cell compartments of LoVo that are expressing high levels of LGR5/EYFP did not show these stem cell-like properties.Thus,cells that exhibit high levels of LGR5/EYFP expression represent the cancer stem cell compartment of Caco-2 colon cancer cells,but not LoVo cells.CONCLUSION Our findings highlight the presence of a spectrum of different ISC-like compartments in different colon cancer cell lines.Their existence is an important consideration for their screening applications and should be taken into account when interpreting drug screening data.We have generated a portable LGR5-reporter that serves as a valuable tool for the identification and isolation of different colon cancer stem cell populations in colon cancer lines. | Samah Abdulaali Alharbi Dmitry A Ovchinnikov Ernst Wolvetang | 2021 | World Journal of Gastroenterology2021，27，15： | 2 |
| 11 | Prevalence and clinical features of colonic diverticulosis in a Middle Eastern population显示文摘AIM: To determine the prevalence, location, associations and clinical features of colonic-diverticulosis and its role as a cause of lower-gastroenterology-bleeding. METHODS: We retrospectively reviewed the medical records of 3649 consecutive patients who under-went a colonoscopy for all indications between 2007 and 2011 at King Khalid University Hospital, Riyadh, Saudi Arabia. The demographic data were collected retrospectively through the hospital's information system, electronic file system, endoscopic e-reports, and manual review of the files by two research assistants. The demographic information included the age, sex, comorbidities and indication for the colonoscopy. The association among colonic polyps, comorbidities and diverticular disease was also measured.RESULTS: A total of 270 patients out of 3649 were diagnosed with colonic diverticulosis, with a prevalence of 7.4%. The mean age was 60.82 years ± 0.833, (range 12-110). Females comprised 38.89% (95%CI: 33-44.7) of the study population. The major symp-toms were rectal bleeding in 33.6%, abdominal pain in 19.3%, constipation in 12.8% and anemia in 6%. Diverticula were predominantly left-sided (sigmoid and descending colon) in 62%, right-sided in 13% and in multiple locations in 25%. There was an association between the presence of diverticulosis and adenomatous polyps (Pvalue < 0.001), hypertension (P-value < 0.0001) and diabetes mellitus (P-value < 0.0016). Diverticular disease was the second most common cause of lower gastrointestinal bleeding, in 33.6% (95%CI: 27.7-39.4), after internal hemor-rhoids, in 44.6% (95%CI: 40.3-48.9). On multivariable logistic regression, hypertension (OR = 2.30; 95%CI: 1.29-4.10), rectal bleeding (OR = 2.57; 95%CI: 1.50-4.38), and per year increment in age (OR = 1.05; 95%CI: 1.03-1.07) were associated with diverticulosis but not with bleeding diverticular disease. Limitations: A small proportion of the patients included had colo-noscopies performed as a screening test.CONCLUSION: Colonic-diverticulosis was found to have a low prevalence, be predominantly left-sided and associated with adenomatous-polyps. Age, hypertension and rectal bleeding predict the presence of diverticular disease. | Nahla Azzam Abdulrahman M Aljebreen Othman Alharbi Majid A Almadi | 2013 | World Journal of Gastrointestinal Endoscopy2013，5，8： | 2 |
