2Diagnosis of Helicobacter pylori : What should be the gold standard?显示文摘Since the discovery of Helicobacter pylori(H. pylori) in 1983, numerous detection methods for the presence of the bacterium have been developed. Each one of them has been associated with advantages and disadvantages. Noninvasive tests such as serology, 13 C urea breath test(UBT) and stool antigen tests are usually preferred by the clinicians. Serology has its own limitation especially in endemic areas while 13 C UBT is technically very demanding. The stool antigen detection method, although specific, is usually associated with poor sensitivity. The 13 C UBT is believed to be specific, but with present revelation of the fact that stomach is colonized by many other urease producing bacteria makes it questionable. Histology, culture, rapid urease test and polymerase chain reaction(PCR) are the tests which are carried out on antral biopsies collected by invasive means. Histology has been proposed to be very sensitive and specific but the question is how by simply looking the morphology of the bacteria in the microscope, one can claim that the curved bacterium is exclusively H. pylori. Rapid urease test(RUT), the doctor's test, is also challenged because the presence of other urease producing bacteria in the stomach cannot be denied. Moreover, RUT has been reported with poor sensitivity specially, when density of the bacterium is low. Isolation of H. pylori is essential to investigate its growth requirements, antibiotic susceptibility testing, studying virulence factor to develop vaccine and many more explorations. It has also got several disadvantages i.e., special condition for transporting, media, incubation and few days waiting for the colonies to appear, apart from the speed essentially needed to process the specimens. Till date, majority of the microbiological laboratories in the world are not equipped and trained to isolate such fastidious bacterium. The option left is PCR methods to detect H. pylori 's DNA in gastric mucosa, gastric juice, saliva, dental plaques and environmental specimens. There are speculations for false positivity due to detection of non-pylori Helicobacters due to genetic sharing; and false negativity due to low bacterial counts and presence of PCR inhibitors. However, specimen collection, transportation and processing do not require speed and special conditions. PCR based diagnosis may be considered as gold standard by designing primers extremely specific to H. pylori and targeting at least more than one conserved genes. Similarly specificity of PCR may be improved by use of internal Primers. Further, nested PCR will take care of false negatives by countering the effect of PCR inhibitors and low bacterial counts. Therefore, nested PCR based methods if performed properly, may be proposed as gold standard test.Saurabh Kumar Patel Chandra Bhan Pratap Ashok Kumar Jain Anil Kumar Gulati Gopal Nath 2014World Journal of Gastroenterology2014,20,36:30
3腹腔镜辅助结直肠癌手术并发症相关风险因素分析显示文摘目的:探讨腹腔镜辅助结直肠癌手术并发症的相关风险因素,为临床治疗、有效预防和减少术后并发症提供必要依据。方法:收集重庆医科大学附属第一医院胃肠外科2007年1月至2009年9月行腹腔镜辅助手术治疗的结直肠癌患者165例,建立数据库。选择性别、年龄、合并症、ASA分级,腹部手术史、TNM分期、手术时间、术中失血、中转开腹等因素,以及吻合口漏、肠梗阻、切口疝、深静脉血栓、术后出血、肺部感染、低蛋白血症、切口感染、裂开等术后并发症。用SPSS 17.0统计软件进行单因素(卡方检验以及对数似然比检验)和多因素分析(Logistic回归检验),寻找引起术后并发症发生的相关因素。结果:单因素分析显示,肺部疾病(P=0.046)以及手术时间≥180min(P=0.034)与腹腔镜辅助结直肠癌手术并发症有关。多因素分析显示,肺部疾病(OR值为4.474,95%可信区间1.282~15.617),手术时间(OR值为5.018,95%可信区间1.592~15.815)是腹腔镜辅助结直肠癌手术并发症发生的独立危险因素。结论:合并肺部疾病和手术时间是腹腔镜辅助结直肠癌手术并发症发生的独立危险因素。腹腔镜辅助结直肠癌手术需要术前严格评估,适当的病例选择提高患者对气腹和手术等因素的耐受能力;手术困难时果断中转开腹,有结直肠手术经验的医生实行手术缩短手术时间,才能取得较好的临床效果。沈雄飞 程勇 Gopall Jayprakash 徐维 2010中国肿瘤临床2010,37,23:23
4Characterization of hepatic progenitors from human fetal liver during second trimester显示文摘AIM: To enrich hepatic progenitors using epithelial cell adhesion molecule (EpCAM) as a marker from human fetal liver and investigate the expression of human leukocyte antigen (HLA) and their markers associated with hepatic progenitor cells. METHODS: EpCAM +ve cells were isolated using magnetic cell sorting (MACS) from human fetuses (n = 10) at 15-25 wk gestation. Expression of markers for hepatic progenitors such as albumin, alpha-fetoprotein (AFP), CD29 (integrin β1), CD49f (integrin α6) and CD90 (Thy 1) was studied by using flow cytometry, immunocytochemistry and RT-PCR; HLA class Ⅰ (A, B, C) and class Ⅱ (DR) expression was studied by flow cytometry only. RESULTS: FACS analysis indicated that EpCAM +ve cells were positive for CD29, CD49f, CD90, CD34, HLA class Ⅰ, albumin and AFP but negative for HLA class Ⅱ (DR) and CD45. RT PCR showed that EpCAM +ve cells expressed liver epithelial markers (CK18), biliary specific marker (CK19) and hepatic markers (albumin, AFP). On immunocytochemical staining, EpCAM +ve cells were shown positive signals for CK18 and albumin. CONCLUSION: Our study suggests that these EpCAM +ve cells can be used as hepatic progenitors for cell transplantation with a minimum risk of alloreactivity and these cells may serve as a potential source for enrichment of hepatic progenitor.Mekala Subba Rao Aleem Ahmed Khan Nyamath Parveen Mohammed Aejaz Habeeb Chittoor Mohammed Habibullah Gopal Pande 2008World Journal of Gastroenterology2008,14,37:16
5Role of bacteria in carcinogenesis, with special reference to carcinoma of the gallbladder显示文摘Carcinoma of the gallbladder (CaGB) is the fifth commonest gastrointestinal tract cancer and is endemic in several countries. The interplay of genetic susceptibility, infections, and life style factors has been proposed to be responsible for carcinogenesis of gallbladder. Persistence of infection leading to chronic inflammation, and production of certain toxins and metabolites with carcinogenic potentials, by certain bacteria has been speculated to be involved in the transformation of the gallbladder epithelium. Therefore, any bacteria that have evolved to acquire both of the above carcinogenic mechanisms can cause cancer. Salmonella typhi has been found to be prominently associated with CaGB. Chronic typhoid carriage (persistence) and production of mediators of chronic infl ammation and a genotoxic toxin (cytotoxic distending toxin, CdtB) are also known for this bacterium. Furthermore, the natural concentrating function of the gallbladder might amplify the carcinogenic effect of the mediators of carcinogenesis. In addition to S. typhi, certain species of Helicobacter (H. bilis and H. hepaticus) and Escherichia coli have also been implicated in carcinogenesis. As the isolation rate is verypoor with the presently available culture techniques, the existence of bacteria in a viable but non-cultivable state is quite likely; therefore, sensitive and specif ic molecular techniques might reveal the etiological role of bacterial infection in gallbladder carcinogenesis. If bacteria are found to be causing cancers, then eradication of such infections might help in reducing the incidence of some cancers.Gopal Nath Anil K Gulati Vijay K Shukla 2010World Journal of Gastroenterology2010,16,43:12

8Congenital pulmonary airway malformation: A report of two cases显示文摘Congenital pulmonary airway malformation(CPAM), previously known as congenital cystic adenomatoid malformation is a congenital disorder of the lung similar to bronchopulmonary sequestration. In CPAM, usually an entire lobe of lung is replaced by a non-working cystic piece of abnormal lung tissue. This abnormal tissue will never function as normal lung tissue. The underlying cause for CPAM is not known. It occurs in approximately 1 in every 30000 pregnancies. The association between CPAM and malignancy has been well documented. There is a small risk(0.7%) of malignant transformation within the cyst. So early diagnosis and surgical resection is important to prevent the grave complications. Herein, we are reporting two interesting cases of CPAM and one belonged to Type Ⅱ and other belonged to Type Ⅲ of Stocker's classification.Saroj Bolde Smita Pudale Gopal Pandit Kirti Ruikar Sachin B Ingle 2015World Journal of Clinical Cases2015,3,5:5
9HIDA scan for functional gallbladder disorder: ensure that you know how the scan was done显示文摘BACKGROUND: Despite the increasing use of fatty meal(FM) as a substitute for cholecystokinin(CCK) in pain reproduction during hepato-imino-diacetic acid(HIDA) scan in functional gallbladder disorder, there are no studies comparing the differences between CCK and FM. The present study was to compare the efficacy of FM in comparison of CCK in FGBD application. METHODS: Patients undergoing HIDA scans from August 2013 to May 2014 were divided into two groups: those undergoing CCK-stimulated HIDA scan versus FM-stimulated HIDA scan. These groups were compared according to demographics and HIDA results.RESULTS: Of 153 patients, 70 received CCK and 83 FM. There was no difference regarding age, gender, gallstones, gallbladder ejection fraction and time to visualization. However, significantly more of the patients receiving CCK than FM experienced pain reproduction(61% vs 30%, P<0.01).CONCLUSIONS: Stimulation of gallbladder contractility with a FM during HIDA is less than half as likely to reproduce biliary symptoms compared to CCK, despite similar ejection fractions and other parameters. It is essential that providers account for this difference when counseling patients regarding cholecystectomy for functional gallbladder disorder.Naeem Goussous Hadia Maqsood Ethan Spiegler Gopal C Kowdley Steven C Cunningham 2017Hepatobiliary & Pancreatic Diseases International2017,16,2:5
10Effect of omeprazole and domperidone on adult asthmatics with gastroesophageal reflux显示文摘AIM: To study the effect of combined omeprazole (Ome) and domperidone (Dom) therapy on asthma symptoms and pulmonary function in asthmatics with gastroesoph- ageal reflux. METHODS: We selected 198 asthmatics with gastroesophageal reflux diagnosed by 24-h esophageal pH monitoring to receive Ome 20 mg twice daily and Dom 10 mg three times daily or placebo for 16 wk (1:1 double-blind randomization). Spirometry was done at baseline and af- ter 16 wk of treatment. The primary outcome measures were: mean daily daytime and nighttime asthma symp- tom scores. Mean daily reflux symptom scores, albuterol use as rescue medication (number of puffs), daytime and nighttime peak expiratory flow rate (PEFR), postbroncho- dilator forced expiratory volume in 1 second (FEV1) and postbronchodilator forced vital capacity (FVC) were secondary outcome measures. RESULTS: Comparison of mean change from baseline between antireflux therapy and placebo groups revealed significant reduction in daytime asthma symptom score (17.4% vs 8.9%), nighttime asthma symptom score (19.6% vs 5.4%), reflux symptom score (8.7% vs 1.6%) and rescue medication use (23.2% vs 3.1%) after antire- flux therapy compared to mean change in placebo group (P < 0.001). There was significant improvement in morn- ing PEFR (7.9% vs 0.2%), evening PEFR (9.8% vs 0.5%), FEV1 (11.1% vs 3.78%) and FVC (9.3% vs 1.52%) in the antireflux therapy group compared to placebo on compar-ing the mean change from baseline after 16 wk (P < 0.01).Bhavneesh Sharma Manisha Sharma Mradul Kumar Daga Gopal Krishan Sachdev Elliott Bondi 2007World Journal of Gastroenterology2007,13,11:5
11Pseudomonas fluorescens-like bacteria from the stomach:A microbiological and molecular study显示文摘AIM:To characterize oxidase-and urease-producing bacterial isolates,grown aerobically,that originated from antral biopsies of patients suffering from acid peptic diseases.METHODS:A total of 258 antral biopsy specimens were subjected to isolation of bacteria followed by tests for oxidase and urease production,acid tolerance and aerobic growth.The selected isolates were further characterized by molecular techniques viz.amplifications for 16S rRNA using universal eubacterial and HSP60 gene specific primers.The amplicons were subjected to restriction analysis and partial sequencing.A phylogenetic tree was generated using unweighted pair group method with arithmetic mean(UPGMA) from evolutionary distance computed with bootstrap test of phylogeny.Assessment of acidity tolerance of bacteria isolated from antrum was performed using hydrochloric acid from 10-7 mol/L to 10-1 mol/L.RESULTS:Of the 258 antral biopsy specimens collected from patients,179(69.4%) were positive for urease production by rapid urease test and 31%(80/258) yielded typical Helicobacter pylori(H.pylori) after 5-7 d of incubation under a microaerophilic environment.A total of 240(93%) antral biopsies yielded homogeneous semi-translucent and small colonies after overnight incubation.The partial 16S rRNA sequences revealed that the isolates had 99% similarity with Pseudomonas species.A phylogenetic tree on the basis of 16S rRNA sequences denoted that JQ927226 and JQ927227 were likely to be related to Pseudomonas fluorescens(P.fluorescens).On the basis ofHSP60 sequences applied to the UPGMA phylogenetic tree,it was observed that isolated strains in an aerobic environment were likely to be P.fluorescens,and HSP60 sequences had more discriminatory potential rather than 16S rRNA sequences.Interestingly,this bacterium was acid tolerant for hours at low pH.Further,a total of 250(96.9%) genomic DNA samples of 258 biopsy specimens and DNA from 240 bacterial isolates were positive for the 613 bp amplicons by targeting P.fluorescens-specific conserved putative outer membrane protein gene sequences.CONCLUSION:This study indicates that bacterial isolates from antral biopsies grown aerobically were P.fluorescens,and thus acid-tolerant bacteria other than H.pylori can also colonize the stomach and may be implicated in pathogenesis/protection.Saurabh Kumar Patel Chandra Bhan Pratap Ajay Kumar Verma Ashok Kumar Jain Vinod Kumar Dixit Gopal Nath 2013World Journal of Gastroenterology2013,19,7:4
12Evaluation of anti-bacterial and anti-oxidant potential of an drographolide and echiodinin isolated from callus culture of Andrographis paniculata Nees显示文摘Objective:To evaluate the anti-bacterial and anti-oxidant activity of and rographolide(AND)and echiodinin(ECH)of Andrographis paniculata.Methods:In this study,an attempt has been made to demonstrate the anti-microbial and anti-oxidant activity of isolated AND and ECH by broth micro-dilution method and 2,2-dipheny l-2-picryl-hydrazyl(DPPH)assay,respectively.Structure elucidation was determined by electro-spray ionization-MSD,NMR(1H and13C)and IR spectra.Results:AND was effective against most of the strains tested including Mycobacterium smegmatis,showing broad spectrum of growth inhibition activity with Minimum inhibitory concentration values againstStaphylococcus aureus(100μg/mL),Streptococcus thermophilus(350μg/mL)Bacillus subtilis(100μg/mL),Escherichia coli(50μg/mL),Mycobacterium smegmatis(200μg/mL),Klebsiella pneumonia(100μg/mL),andPseudomonas aeruginosa(200μg/mL).ECH showed specific anti-bacterial activity against Staphylococcus aureus,Escherichia coli,Bacillus subtilis and Pseudomonas aeruginosaat a concentration higher than 225μg/mL.Both AND and ECH were not effective against the two yeast strains,Candida albicansand Saccharomyces cerevisiae tested in this study.Conclusion:This preliminary study showed promising anti-bacterial activity and moderate free radical scavenging activity of AND and ECH,and it may provide the scientific rationale for its popular folklore medicines.Mohammed Arifullah Nima Dandu Namsa Manabendra Mandal Kishore Kumar Chiruvella Paritala Vikrama Ghanta Rama Gopal 2013Asian Pacific Journal of Tropical Biomedicine2013,3,8:4

14Quantification of organic carbon and primary nutrients in litter and soil in a foothill forest plantation of eastern Himalaya显示文摘The present study was an effort to understand the amount of litter fall and its subsequent decomposition and quantify the release of available nutrients and soil physicochemical characteristics in plantations of four forest tree species(Lagerstroemia parviflora, Tectona grandis, Shorea robusta and Michelia champaca) in the Chilapatta Reserve Forest of the Cooch Behar Wildlife Division in the Terai zone of West Bengal, India. The most litter(5.61 Mg ha^(-1))was produced by T. grandis plantation and the least(4.72 Mg ha^(-1)) by L. parviflora. The material turnover rate to the soil through decomposition from total litter was fastest during the first quarter of the year and subsequently decreased during the next two quarters. The material turnover rate was only 1 year, which indicates that more than90% of the total litter produced decomposed within a year.The available primary nutrient content in litter varied across the four plantations over the year. The plantations generally did not significantly influence the soil physical characteristics but did significantly influence the availability of primary nutrients and organic carbon at two depths(1–15 and16–30 cm) over the year. The availability of soil primary nutrients in the four plantations also increased gradually from the first quarter of the year to the third quarter and then decreased during the last quarter to the same level as in the first quarter of the year at both depths. The availability for soil organic carbon in the plantations followed a similar trend. The amount of litter produced and the material turnover in the soil in the different plantations differed, influencing the nutrient availability and organic carbon at the plantations. The amount of soil organic carbon was highest for T. grandis(2.52 Mg ha^(-1)) and lowest for L. parviflora(2.12 Mg ha^(-1)). Litter is the source of soil organic matter,and more the litter that is produced by the plantations, the higher will be the content and amount of soil organic carbon in the plantation.Gopal Shukla Nazir A.

15Soil and water conservation measures improve soil carbon sequestration and soil quality under cashews显示文摘Land degradation is becoming a serious problem in the west coast region of India where one of the world's eight biodiversity hotspots,the‘Western Ghats’,is present.Poor land management practices and high rainfall have led to increasing problems associated with land degradation.A long-term(13-year)experiment was done to evaluate the impact of soil and water conservation measures on soil carbon sequestration and soil quality at three different depths under cashew nut cultivation on a 19%slope.Five soil and water conservation measures-continuous contour trenches,staggered contour trenches,halfmoon terraces,semi-elliptical trenches,and graded trenches all with vegetative barriers of Stylosanthes scabra and Vetiveria zizanoides and control were evaluated for their influence on soil properties,carbon sequestration,and soil quality under cashews.The soil and water conservation measures improved significantly the soil organic carbon,soil organic carbon stock,carbon sequestration rate and microbial activity compared to the control condition(without any measures).Among the measures tested,continuous contour trenches with vegetative barriers outperformed the others with respect to soil organic carbon stock,sequestration rate,and microbial activity.The lower metabolic quotient with the measures compared to the control indicated alleviation of environmental stress on microbes.Using principal component analysis and a correlation matrix,a minimum dataset was identified as the soil available nitrogen,bulk density,basal soil respiration,soil pH,acid phosphatase activity,and soil available boron and these were the most important soil properties controlling the soil quality.Four soil quality indices using two summation methods(additive and weighted)and two scoring methods(linear and non-linear)were developed using the minimum dataset.A linear weighted soil quality index was able to statistically differentiate the effect of soil and water conservation measures from that of the control.The highest value of the soil quality index of 0.98 was achieved with continuous contour trenches with a vegetative barrier.The results of the study indicate that soil and water conservation measures for cashews are a potential strategy to improve the soil carbon sequestration and soil quality along with improving crop productivity and reducing the erosion losses.Gopal Ramdas Mahajan Bappa Das Sandrasekaran Manivannan Begur Lakshminarasimha Manjunath Ram Ratan Verma Sujeet Desai Rahul Mukund Kulkarni Ashish Marotrao Latare Reshma Sale Dayesh Murgaonkar Kiran Puna Patel Shaiesh Morajkar Ashwini Desai Natasha Barnes Heena Mulla 2021International Journal of Sediment Research2021,36,2:4
16In-vitro scolicidal activity of Mallotus philippinensis (Lam.) Muell Arg. fruit glandular hair extract against hydatid cyst Echinococcus granulosus显示文摘Objective: To investigate new scolicidal agent from natural resources to cope with the side effects associated with synthetic drugs in Echinococcosis. Methods: The scolicidal potential of methanolic fruit powder extract (10 and 20 mg/mL) of Mallotus philippinensis ( M. philippinensis ) was investigated. Viability of protoscoleces was confirmed by trypan blue exclusion method, where mortality was observed at concentration of 10 and 20 mg/mL in 60 min treatment against Echinococcus granulosus ( E. granulosus ), under in-vitro conditions with reference to the known standard drug Praziquantel . Results: At concentration 10 and 20 mg/mL, the mortality rate was observed 97% and 99% respectively for 60 min treatment; while up to 93% mortality was observed with 20 mg/mL for only 10 min treatment. The concentration above 20 mg/mL for above 2 h showed 100% mortality, irrespective of further incubation. Conclusions: As compared with the standard anti-parasitic drug Praziquantel our extract has significant scolicidal activity with almost no associated side effects.Mayank Gangwar Vijay C Verma Tryambak D Singh Sushil K Singh RK Goel Gopal Nath 2013Asian Pacific Journal of Tropical Medicine2013,6,8:3
17Modelling Solitary Waves and Its Impact on Coastal Houses with SPH Method显示文摘The interaction between solid structures and free-surface flows is investigated in this study.A Smoothed Particle Hy-drodynamics(SPH)model is used in the investigation and is verified against analytical solutions and experimental obser-vations.The main aim is to examine the effectiveness of a tsunami-resistant house design by predicting the wave loads on it.To achieve this,the solitary wave generation and run-up are studied first.The solitary wave is generated by allowing a heavily weighted block to penetrate into a tank of water at one end,and the near-shore seabed is modelled by an in-clined section with a constant slope.Then,the SPH model is applied to simulate the three-dimensional flows around dif-ferent types of houses under the action of a solitary wave.It has been found that the tsunami-resistant house design re-duces the impact force by a factor of three.LIANG Dong-fang N.

20Risk-adjustment in hepatobiliarypancreatic surgery显示文摘AIM: The present study evaluates the performance of the POSSUM, the American Society of Anesthetists (ASA),APACHE and Childs classification in predicting mortality and morbidity in hepatopancreaticobiliary (HPB) surgery.We describe especially the limitations and advantages of risk in stratifying the patients.METHODS: We investigated 177 randomly chosen patients undergoing eledive complex HPB surgery in a single institution with a total of 71 pre-operative and intra-operative risk factors.Primary endpoint was in-hospital mortality and morbidity.Ordered logistic regression analysis was used to identify individual predictors of operative morbidity and mortality.RESULTS: The operative mortality in the series was 3.95% .This compared well with the p-POSSUM and APACHE predicted mortality of 4.31% and 4.29% respectively. Postoperative complications amounted to 45% with 24 (13.6%)patients having a major adverse event. On multivariate analysis the pre-operative POSSUM physiological score (OR = 1.18,P = 0.009) was superior in predicting complications compared to the ASA (P = 0.108), APACHE (P = 0.117)or Childs classification (P = 0.136). In addition, serum sodium, creatinine, international normalized ratio (INR),pulse rate, and intra-operative blood loss were independent risk factors. A combination of the POSSUM variables and INR offered the optimal combination of risk factors for risk prognostication in HPB surgery.CONCLUSION: Morbidity for elective HPB surgery can be accurately predicted and applied in everyday surgical practice as an adjunct in the process of informed consent and for effective allocation of resources for intensive and high-dependency care facilities.Hemant M Kocher Paris P Tekkis Palepu Gopal Ameet G Patel Simon Cottam Irving S Benjamin 2005World Journal of Gastroenterology2005,11,16:3
