| 1 | Carcinogenic Helicobacter pylori in gastric pre-cancer and cancer lesions: Association with tobacco-chewing显示文摘AIM:To investigate the low gastric cancer incidence rate relative to the highly prevalent Helicobacter pylori(H.pylori)infection;data relevant to H.pylori infection during gastric carcinogenesis in Indian patients is currently lacking.METHODS:The present study examines the prevalence of H.pylori infection in DNA derived from 156endoscopic gastric biopsies of different disease groups that represent gastric pre-cancer[intestinal metaplasia(n=15),dysplasia(n=15)],cancer[diffuse adenocarcinoma(n=44),intestinal adenocarcinoma(n=21)],and symptomatic but histopathologically-normal controls(n=61).This was done by generic ureC polymerase chain reaction(PCR)and cagA-specific PCR that could specifically identify the carcinogenic H.pylori strain.RESULTS:Our analysis showed the presence of H.pylori infection in 61%of symptomatic histopathologically-normal individuals,however only 34%of control tissues were harboring the cagA+H.pylori strain.A similar proportion of H.pylori infection(52%)and cagA(26%)positivity was observed in the tumor tissue of the gastric cancer group.In comparison,H.pylori infection(90%)and cagA positivity(73%)were the highest in gastric pre-cancer lesions.In relation to tobacco and alcohol abuse,H.pylori infection showed an association with tobacco chewing,whereas we did not observe any association between tobacco smoking or alcohol abuse with prevalence of H.pylori infection in the tissue of any of the patient groups studied.CONCLUSION:High incidence of H.pylori infection and carcinogenic cagA positive strain in pre-cancer lesions during gastric carcinogenesis may be | Arvind Pandey Satyendra Chandra Tripathi Sutapa Mahata Kanchan Vishnoi Shirish Shukla Sri Prakash Misra Vatsala Misra Suresh Hedau Ravi Mehrotra Manisha DwivediZ Alok C Bharti | 2014 | World Journal of Gastroenterology2014，20，22： | 4 |
| 2 | Molecular dynamics simulation of nanometer scale mechanical properties of hexagonal Mgsingle bondLi alloy显示文摘Nano mechanical behavior of Mgsingle bondLi nanowire is investigated under tension and compression to elicit property alteration due to Li alloying in Mg within hexagonal range.Embedded atom method(EAM)is employed to carry out present simulation work.Nanowire under consideration is supposed to be isotropic and mechanical behavior is uninfluenced by material texture.The elastic modulus,yield strength both in tension and compression is assessed with change in strain rate.Effects of temperature in tension and compression are studied.Results of present simulation work elicit serrated yielding under uniaxial tension,however,twin mediated deformation under compression is completely tuned with previously reported experimental works.This investigation bridges nanometer scale properties to microscale material response,which in turn can be applied for designing suitable robust processing routes of this material. | Avik Mahata Koushik Sikdar | 2016 | Journal of Magnesium and Alloys2016，4，1： | 3 |
