| 1 | Predictive value of C-reactive protein/albumin ratio in acute pancreatitis显示文摘BACKGROUND:Serum C-reactive protein(CRP) increases and albumin decreases in patients with inflammation and infection.However,their role in patients with acute pancreatitis is not clear.The present study was to investigate the predictive significance of the CRP/albumin ratio for the prognosis and mortality in acute pancreatitis patients.METHODS:This study was performed retrospectively with 192 acute pancreatitis patients between January 2002 and June 2015.Ranson scores,Atlanta classification and CRP/albumin ratios of the patients were calculated.RESULTS:The CRP/albumin ratio was higher in deceased patients compared to survivors.The CRP/albumin ratio was positively correlated with Ranson score and Atlanta classification in particular and with important prognostic markers such as hospitalization time,CRP and erythrocyte sedimentation rate.In addition to the CRP/albumin ratio,necrotizing pancreatitis type,moderately severe and severe Atlanta classification,and total Ranson score were independent risk factors of mortality.It was found that an increase of 1 unit in the CRP/albumin ratio resulted in an increase of 1.52 times in mortality risk.A prediction value about CRP/albumin ratio >16.28 was found to be a significant marker in predicting mortality with 92.1% sensitivity and 58.0% specificity.It was seen that Ranson and Atlanta classification were higher in patients with CRP/albumin ratio >16.28 compared with those with CRP/albumin ratio ≤16.28.Patients with CRP/albumin ratio >16.28 had a 19.3 times higher chance of death.CONCLUSION:The CRP/albumin ratio is a novel but promising,easy-to-measure,repeatable,non-invasive inflammationbased prognostic score in acute pancreatitis. | Mustafa Kaplan Ihsan Ates Muhammed Yener Akpinar Mahmut Yuksel Ufuk Baris Kuzu Sabite Kacar Orhan Coskun Ertugrul Kayacetin | 2017 | Hepatobiliary & Pancreatic Diseases International2017,16,4: | 53 |
| 2 | Treatment of portal hypertension显示文摘Portal hypertension is the main complication of cirrhosis and is defined as an hepatic venous pressure gradient(HVPG) of more than 5 mmHg.Clinically significant portal hypertension is defined as HVPG of 10 mmHg or more.Development of gastroesophageal varices and variceal hemorrhage are the most direct consequence of portal hypertension.Over the last decades significant advancements in the field have led to standard treatment options.These clinical recommendations have evolved mostly as a result of randomized controlled trials and consensus conferences among experts where existing evidence has been reviewed and future goals for research and practice guidelines have been proposed.Management of varices/variceal hemorrhage is based on the clinical stage of portal hypertension.No specific treatment has shown to prevent the formation of varices.Prevention of first variceal hemorrhage depends on the size/characteristics of varices.In patients with small varices and high risk of bleeding,nonselective b-blockers are recommended,while patients with medium/large varices can be treated with either b-blockers or esophageal band ligation.Standard of care for acute variceal hemorrhage consists of vasoactive drugs,endoscopic band ligation and antibiotics prophylaxis.Transjugular intrahepatic portosystemic shunt(TIPS) is reserved for those who fail standard of care or for patients who are likely to fail('early TIPS').Prevention of recurrent variceal hemorrhage consists of the combination of b-blockers and endoscopic band ligation. | Khurram Bari Guadalupe Garcia-Tsao | 2012 | World Journal of Gastroenterology2012,18,11: | 44 |
| 3 | Red cell distribution width to platelet ratio: New and promising prognostic marker in acute pancreatitis显示文摘AIM: To evaluate the accuracy of red cell distribution width(RDW) to platelet ratio(RPR) to predict in-hospital mortality in acute pancreatitis(AP).METHODS: Between January 2010 and June 2012, 102 patients with AP were recruited to the study. In this retrospective cohort study, for all subjects, demographic data on hospital admission, AP etiology, comorbid diseases, organ failure assessment, laboratory parameters and length of hospital stay were examined. Additionally, we used a non-invasive prediction method in addition to the RPR to evaluate the disease severity. Multivariate logistic regression analyses were used to evaluate the impact of RPR on hospital admission to predict mortality.RESULTS:The male-female ratio(59/43)was 1.37with a median age of 56.5 years(17-89 years).In both univariate and multivariate analyses,RDW and RPR were presented as independent and significant variables on admission to predict mortality.The RPR obtained on hospital admission was persistently higher amongnon-survivors than among survivors(P<0.0001).The median RPR was 0.000087 in the non-survivor group and 0.000058 in the survivor group.RPR with a cutoff value of 0.000067 presented an area under the curve of 0.783(95%CI:0.688-0.878)in receiver operating characteristic curves and could predict the mortality of approximately 80%of the patients. | Erdin etinkaya Kazim Senol Baris Saylam Mesut Tez | 2014 | World Journal of Gastroenterology2014,20,39: | 38 |
| 4 | Gastric carcinogenesis显示文摘Gastric cancer is the second most common cancer worldwide and the second most common cause of cancer-related deaths. Despite complete resection of gastric cancer and lymph node dissection, as well as improvements in chemotherapy and radiotherapy, there are still 700 000 gastric cancer-related deaths per year worldwide and more than 80% of patients with advanced gastric cancer die of the disease or recurrent disease within 1 year after diagnosis. None of the treatment modalities we have been applying today can influence the overall survival rates:at present, the overall 5-year relative survival rate for gastric cancer is about 28%. Cellular metaplasia due to chronic inflammation, injury and repair are the most documented processes for neoplasia. It appears that chronic inflammation stimulates tumor development and plays a critical role in initiating, sustaining and advancing tumor growth. It is also evident that not all inflammation is tumorigenic. Additional mutations can be acquired, and this leads to the cancer cell gaining a further growth advantage and acquiring a more malignant phenotype. Intestinalization of gastric units, which is called 'intestinal metaplasia'; phenotypic antralization of fundic units, which is called 'spasmolytic polypeptide-expressing metaplasia'; and the development directly from the stem/progenitor cellzone are three pathways that have been described for gastric carcinogenesis. Also, an important factor for the development of gastrointestinal cancers is peritumoral stroma. However, the initiating cellular event in gastric metaplasia is still controversial. Understanding gastric carcinogenesis and its precursor lesions has been under intense investigation, and our paper attempts to highlight recent progress in this field of cancer research. | Ismail Gomceli Baris Demiriz Mesut Tez | 2012 | World Journal of Gastroenterology2012,18,37: | 25 |
| 5 | Pyogenic liver abscess: Changing patterns in approach显示文摘AIM: To define optimum management of the pyogenic liver abscess and assess new trends in treatment. METHODS: One hundred and sixty nine patients with pyogenic liver abscess managed at Sher-i-Kashmir In- stitute of Medical Sciences, Srinagar, Kashmir (India) from July 2001 to August 2006 were studied to evaluate and define the optimum treatment. RESULTS: Mortality in the surgically treated group of patients was 9.4% (12/119), while those treated non-surgically had a fatality rate of 16.66% (7/42). Multiple liver abscesses treated surgically had a surprisingly low mortality of 30%. The biliary tract (64.97%) was the most common cause of liver abscess. Multiple abscesses, mixed organisms and abscess complications are all associated with a significantly increased mortality. However, the lethality of the primary disease process was the most important factor in determining survival.CONCLUSION: Transperitoneal surgical drainage and antibiotics are the mainstay of treatment. Percutaneous drainage is recommended for high risk patients only. | Ajaz A Malik Shams UL Bari Khawaja Abdul Rouf Khurshid Alam Wani | 2010 | World Journal of Gastrointestinal Surgery2010,2,12: | 15 |
| 6 | Towards an Artificial Intelligence Framework for Data-Driven Prediction of Coronavirus Clinical Severity显示文摘The virus SARS-CoV2,which causes the Coronavirus disease COVID-19 has become a pandemic and has spread to every inhabited continent.Given the increasing caseload,there is an urgent need to augment clinical skills in order to identify from among the many mild cases the few that will progress to critical illness.We present a first step towards building an artificial intelligence(AI)framework,with predictive analytics(PA)capabilities applied to real patient data,to provide rapid clinical decision-making support.COVID-19 has presented a pressing need as a)clinicians are still developing clinical acumen given the disease’s novelty,and b)resource limitations in a rapidly expanding pandemic require difficult decisions relating to resource allocation.The objectives of this research are:(1)to algorithmically identify the combinations of clinical characteristics of COVID-19 that predict outcomes,and(2)to develop a tool with AI capabilities that will predict patients at risk for more severe illness on initial presentation.The predictive models learn from historical data to help predict specifically who will develop acute respiratory distress syndrome(ARDS),a severe outcome in COVID-19.Our experimental results based on two hospitals in Wenzhou,Zhejang,China identify features most predictive of ARDS in COVID-19 initial presentation which would not have stood out to clinicians.A mild increase in elevated alanine aminotransferase(ALT)(a liver enzyme)),a presence of myalgias(body aches),and an increase in hemoglobin,in this order,are the clinical features,on presentation,that are the most predictive.Those two centers’COVID-19 case series symptoms on initial presentation can help predict severe outcomes.Predictive models that learned from historical data of patients from two Chinese hospitals achieved 70%to 80%accuracy in predicting severe cases. | Xiangao Jiang Megan Coffee Anasse Bari Junzhang Wang Xinyue Jiang Jianping Huang Jichan Shi Jianyi Dai Jing Cai Tianxiao Zhang Zhengxing Wu Guiqing He Yitong Huang | 2020 | Computers, Materials & Continua2020,,4: | 15 |

| 9 | Adaptive mode switching of hypersonic morphing aircraft based on type-2 TSK fuzzy sliding mode control显示文摘This paper presents a novel adaptive mode switching scheme for hypersonic morphing aircraft with retracted winglets based on type-2 Takagi-Sugeno-Kang(TSK) fuzzy sliding mode control. For each of retracting and stretching modes, a specific sliding mode controller has been adopted. Drawing upon input/output linearization to globally linearize the nonlinear model of the hypersonic aircraft at first, a type-2 TSK fuzzy logic system is devised for robust mode switching between these sliding mode controllers. For rapid stabilization of the system, the adaptive law for mode switching is designed using a direct constructive Lyapunov analysis.Simulation results demonstrate the stability and smooth transition using the proposed switched control scheme. | JIAO Xin FIDAN Baris JIANG Ju KAMEL Mohamed | 2015 | Science China(Information Sciences)2015,58,7: | 8 |

| 11 | A silybin-phospholipids complex counteracts rat fatty liver degeneration and mitochondrial oxidative changes显示文摘AIM:To investigate the effectiveness of antioxidant compounds in modulating mitochondrial oxidative alterations and lipids accumulation in fatty hepatocytes.METHODS:Silybin-phospholipid complex containing vitamin E(Realsil) was daily administered by gavage(one pouch diluted in 3 mL of water and containing 15 mg vitamin E and 47 mg silybin complexed with phospholipids) to rats fed a choline-deprived(CD) or a high fat diet [20% fat,containing 71% total calories as fat,11% as carbohydrate,and 18% as protein,high fat diet(HFD)] for 30 d and 60 d,respectively.The control group was fed a normal semi-purified diet containing adequate levels of choline(35% total calories as fat,47% as carbohydrate,and 18% as protein).Circulating and hepatic redox active and nitrogen regulating molecules(thioredoxin,glutathione,glutathione peroxidase),NO metabolites(nitrosothiols,nitrotyrosine),lipid peroxides [malondialdehyde-thiobarbituric(MDA-TBA)],and pro-inflammatory keratins(K-18) were measured on days 0,7,14,30,and 60.Mitochondrial respiratory chain proteins and the extent of hepatic fatty infiltration were evaluated.RESULTS:Both diet regimens produced liver steatosis(50% and 25% of liver slices with CD and HFD,respectively) with no signs of necro-inflammation:fat infiltration ranged from large droplets at day 14 to disseminated and confluent vacuoles resulting in microvesicular steatosis at day 30(CD) and day 60(HFD).In plasma,thioredoxin and nitrosothiols were not significantly changed,while MDA-TBA,nitrotyrosine(from 6 ± 1 nmol/L to 14 ± 3 nmol/L day 30 CD,P < 0.001,and 12 ± 2 nmol/L day 60 HFD,P < 0.001),and K-18(from 198 ± 20 to 289 ± 21 U/L day 30 CD,P < 0.001,and 242 ± 23 U/L day 60 HFD,P < 0.001) levels increased significantly with ongoing steatosis.In the liver,glutathione was decreased(from 34.0 ± 1.3 to 25.3 ± 1.2 nmol/mg prot day 30 CD,P < 0.001,and 22.4 ± 2.4 nmol/mg prot day 60 HFD,P < 0.001),while thioredoxin and glutathione peroxidase were initially increased and then decreased.Nitrosothiols were constantly increased.MDA-TBA levels were five-fold increased from 9.1 ± 1.2 nmol/g to 75.6 ± 5.4 nmol/g on day 30,P < 0.001(CD) and doubled with HFD on day 60.Realsil administration significantly lowered the extent of fat infiltration,maintained liver glutathione levels during the first half period,and halved its decrease during the second half.Also,Realsil modulated thioredoxin changes and the production of NO derivatives and significantly lowered MDA-TBA levels both in liver(from 73.6 ± 5.4 to 57.2 ± 6.3 nmol/g day 30 CD,P < 0.01 and from 27.3 ± 2.1 nmol/g to 20.5 ± 2.2 nmol/g day 60 HFD,P < 0.01) and in plasma.Changes in mitochondrial respiratory complexes were also attenuated by Realsil in HFD rats with a major protective effect on Complex Ⅱ subunit CII-30.CONCLUSION:Realsil administration effectively contrasts hepatocyte fat deposition,NO derivatives formation,and mitochondrial alterations,allowing the liver to maintain a better glutathione and thioredoxin antioxidant activity. | Ignazio Grattagliano Catia V Diogo Maria Mastrodonato Ornella de Bari Michele Persichella David QH Wang Adriana Liquori Domenico Ferri Maria Rosaria Carratù Paulo J Oliveira Piero Portincasa | 2013 | World Journal of Gastroenterology2013,19,20: | 6 |
| 12 | Where are we at with short bowel syndrome and small bowel transplant?显示文摘Intestinal failure can be defined as the critical reduction of functional gut mass below the minimal amount necessary for adequate digestion and absorption to satisfy body nutrient and fluid requirements in adults or children.Short bowel syndrome(SBS)is characterized by a state of malabsorption following extensive resection of the small bowel.SBS may occur after resection of more than 50%and is certain after resection of more than 70%of the small intestine,or if less than 100 cm of small bowel is left.Several treatment modalities other than total parenteral nutrition,including hormones(recombinant human growth hormone,glucagon-like peptide-2)and tailoring surgeries(Bianchi procedure,serial transverse enteroplasty),had been proposed,however these were either experimental or inefficient.Small bowel transplant is a rather new approach for SBS.The once feared field of solid organ transplantation is nowadays becoming more and more popular,even in developing countries.This is partially secondary to the developments in immunosuppressive strategy.In this regard,alemtuzumab deserves special attention.There are more complex surgeries,such as multivisceral transplantation,for multi-organ involvement including small bowel.This latter technique is relatively new when compared to small bowel transplant,and is performed in certain centers worldwide.In this review,an attempt is made to give an insight into small bowel syndrome,small bowel transplantation,and related issues. | Baris Dogu Yildiz | 2012 | World Journal of Transplantation2012,2,6: | 6 |
| 13 | One-step electrochemical reduction of stibnite concentrate in molten borax显示文摘In this study,antimony production from a stibnite concentrate(Sb2S3)was performed in one step using a molten salt electrolysis method and borax as an electrolyte.Electrochemical reduction of the stibnite concentrate was performed at 800℃under galvanostatic conditions and explained in detail by the reactions and intermediate compounds formed in the borax.The effects of current density(100 800 mA cm^-2)and electrolysis time(10 40 min)on cathodic current efficiency and antimony yields were systematically investigated.During the highest current efficiency,which was obtained at 600 mA cm^-2,direct metal production was possible with 62%cathodic current efficiency and approximately 6 kWh/kg energy consumption.At the end of the 40-min electrolysis duration at 600 mA cm^-2 current density,antimony reduction reached 30.7 g and 99%of the antimony fed to the cell was obtained as metal. | Levent Kartal Mehmet Baris Daryal Güldem Kartal Sireli Servet Timur | 2019 | International Journal of Minerals,Metallurgy and Materials2019,26,10: | 6 |

| 17 | Soil fixation and erosion control by Haloxylon persicum roots in arid lands, Iran显示文摘Vegetation roots contribute to soil fixation and reinforcement, thus improving soil resistance against erosion. Generally, the amount of soil fixation presented by roots mainly depends on root density and tensile strength. In the present study, we conducted the research in order to further understand the biotechnical properties of Haloxylon persicum and also to quantify its role in increasing soil cohesion in arid lands of Iran. Ten H. persicum shrubs were randomly selected for root distribution and strength investigations, in which five samples were set on flat terrain and other five samples on a moderate slope terrain. The profile trench method was used to assess the root area ratio(RAR) as the index of root density and distribution. Two profiles were dug around each sample, up and downslope for sloped treatment and north and south sides for flat treatment. The results showed that RAR increased with increasing soil depth and significantly decreased in 40–50 cm layers of downhill(0.320%) and 50–60 cm for uphill(0.210%). The minimum values for the northward and southward profiles were 0.003% and 0.003%, respectively, while the maximum values were 0.260% and 0.040%, respectively. The relationship between the diameter of root samples and root tensile strength followed a negative power function, but tensile force increased with increasing root diameter following a positive power function. The pattern of increased cohesion changes in soil profile was relatively similar to RAR curves. The maximum increased cohesion due to the presence of roots in uphill and downhill sides were 0.470 and 1.400 kPa, respectively. In the flat treatment, the maximum increased cohesions were 0.570 and 0.610 kPa in northward and southward profiles, respectively. The analysis of variance showed that wind and slope induced stresses did not have any significant effect on the amount of increased cohesion of H. persicum. The findings served to develop knowledge about biotechnical properties of H. persicum root system that can assist in assessing the efficiency of afforestation and restoration measures for erosion control in arid lands. | Ehsan ABDI Hamid R SALEH Baris MAJNONIAN Azade DELJOUEI | 2019 | Journal of Arid Land2019,11,1: | 4 |
| 18 | Locus coeruleus-norepinephrine: basic functions and insights into Parkinson’s disease显示文摘The locus coeruleus is a pontine nucleus that produces much of the brain's norepinephrine.Despite its small size,the locus coeruleus is critical for a myriad of functions and is involved in many neurodegenerative and neuropsychiatric disorders.In this review,we discuss the physiology and anatomy of the locus coeruleus system and focus on norepinephrine's role in synaptic plasticity.We highlight Parkinson's disease as a disorder with motor and neuropsychiatric symptoms that may be understood as aberrations in the normal functions of locus coeruleus. | Bilal Abdul Bari Varun Chokshi Katharina Schmidt | 2020 | Neural Regeneration Research2020,15,6: | 4 |
