| 1 | Spark-generated bubble collapse near or inside a circular aperture and the ensuing vortex ring and droplet formation显示文摘This paper aims to study the oscillation of a sparkgenerated submerged bubble located near or inside a circular aperture made in a flat plate using high-speed visualization technique. In the case of a bubble oscillating near an aperture the initial free surface of the water was set at the bottom surface of the plate. The efects of aperture size and bubblefree surface distance on the bubble behavior as well as on the ensuing droplet dynamics are investigated. It was found that the direction of the bubble reentrant jet was towards the aperture or away from it respectively when the normalized aperture size was smaller or greater than a certain critical value. In addition, a toroidal vortex ring was observed to form, which rotated inwards as it moved away from the aperture. It was also found that if the bubble was incepted at a distance sufciently away from a supercritical size aperture a single droplet could be produced. In the case of a bubble initiated in the middle of a circular aperture submerged just beneath the water free surface, the bubble was found to take the shape of an ellipsoid during its expansion. Then a reentrant jet was initiated and pierced the bubble from its top side. | Abdolrahman Dadvand Mazyar Dawoodian Boo Cheong Khoo Reza Esmaily | 2013 | Acta Mechanica Sinica2013，29，5： | 6 |
| 2 | Non-steroidal anti-inflammatory drugs and statins in relation to colorectal cancer risk显示文摘AIM:To investigate the association between individual or combined use of non-steroidal anti-inflammatory drugs(NSAIDs) or statins and colorectal cancer risk.METHODS:In a population-based case-control study in women,we examined the association between NSAIDs and statin use and the risk of colorectal cancers.We further investigated whether the use of statins modifies the protective effect of NSAIDs.Female cases(n = 669) of colorectal cancer aged 50-74 years were identified from a statewide registry in Wisconsin during 1999-2001.Community control women(n = 1375) were randomly selected from lists of licensed drivers and Medicare beneficiaries.Medication use and risk factor information were gathered during a structured telephone interview.A multivariable logistic regression model was used to calculate odds ratio(OR) and 95% conf idence interval(CI) .RESULTS:Overall,NSAIDs users had a 30% reduction in risk of colorectal cancer(95% CI:0.56-0.88) .Statin use was not associated with colorectal cancer risk(OR = 1.17,95% CI:0.74-1.85) ,regardless of structural type(lipophilic or hydrophilic) ,duration of use,or recency.There was no evidence of an interaction between NSAIDs and statins and colorectal cancer risk(P-interaction = 0.28) .CONCLUSION:Although our results confirm the inverse association between NSAIDs use and colorectal cancer risk,they do not support a risk reduction in statin users,or an interaction effect of combined NSAIDs and statin use. | Mazyar Shadman Polly A Newcomb John M Hampton Karen J Wernli Amy Trentham-Dietz | 2009 | World Journal of Gastroenterology2009，15，19： | 5 |

| 20 | Determining hepatitis C virus genotype distribution among high-risk groups in Iran using real-time PCR显示文摘AIM:To assess hepatitis C virus(HCV)genotype patterns among high-risk Iranian groups,using real-time RT-PCR.METHODS:In this study,we evaluated the distribution of different HCV genotypes among injection drug users and other high-risk groups over a 4-year period(from 2009 to 2012)using real-time polymerase chain reaction(PCR).Sera from 888 HCV-infected patients residing in southern and southwest Iran were genotyped using real-time PCR with common primers and specific probes.These patients were grouped into distinct exposure categories.Illicit drug users constituted the primary group and were further evaluated for HCV genotype distribution and parameters such as age range.RESULTS:Of the examined HCV-infected patients,62%were substance abusers,although the route of transmission could not be determined in approximately 30%of these patients.HCV genotyping revealed that Gt1 was the most prevalent genotype among the drug users as well as among patients with thalassemia,hemophilia,solid organ recipients and those on hemodialysis.Mixed infections were only seen in addict groups,where Gt2 genotype was also found.The highest frequencies in HCV-positive addict patients were observed in the 31-40 age group.Our research also showed that the addiction age has increased,whereas the addiction rate has dropped in this region.Most illicit drug users had more than one risk factor such as tattoo and/or a history of imprisonment.CONCLUSION:This study revealed that the most common HCV-infection route and HCV-genotype in southern and southwest Iran was illicit drug abuse and Gt1,respectively. | Marzieh Jamalidoust Mandana Namayandeh Sadaf Asaei Nasrin Aliabadi Mazyar Ziyaeyan | 2014 | World Journal of Gastroenterology2014，20，19： | 1 |
