Relative Warp Analysis was used in the investigation to determine shell shape divergence. For statistical analysis, Discriminant analysis and KruskalWallis test were performed. The results showed that parasitism in O. quadrasi had significant effects on some morphometric dimensions of the snailapertural and apical sculptures based on the shell shapes. These phenotypic variations accounted for more than 40% of the variance in shell morphology relative to mean shape. Even at low infection levels, 4.05% of the local populations being infected, the effects were even detectable.

For this purpose, we performed various statistical and field investigations to analyse and interpret the main factors, which included temperature, salinity and power stations. Data obtained from the Environment Public Authority, the Ministry of Electricity and Water, and field-work were analysed statistically to determine whether a relationship between dissolved oxygen and other factors exists and which factors have a significant effect on dissolved oxygen. The results revealed varying degrees of dissolved oxygen, temperature and salinity in Kuwait Bay throughout the year, whereas spatial variations were less noticeable. Conversely, power stations increase production during summer months; the Western Doha Station recorded its highest production and the Alshuwaikh its lowest. Based on an analysis of the relationship between dissolved oxygen and other factors, only temperature among the physical factors has an inverse relationship, while dissolved oxygen is controlled positively by the distance from power stations.","PeriodicalId":437476,"journal":{"name":"Journal of medical and bioengineering","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114610864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are a number of suspected casual reasons of this type of carcinoma. The association of viral infection with EC (esophageal carcinoma) has been reported in last 30 years. Human papillomavirus (HPV) is said to be a major aetiology in areas with high incidence of esophageal carcinoma, but the prevalence and the role of HPV virus in the aetiology of esophageal squamous cell carcinoma (ESCC) is still uncertain. In this study we designed to evaluate the prevalence of HPV in EC cases diagnosed in pathology department of Hebei, China. In this study 170 cases that were pathologically diagnosed as esophagealcarcinoma were obtained from department of pathology files at Hebei provincebetween2011-2013. DNA material was extracted from formalin-fixed paraffin-embedded tissues (FFPET) and PCR was performed to detect HPV genome. In this study negative and positive control were used for HPV 16/18 and beta-globin PCR as internal control. More than 95% of FFPETs had acceptable result in DNA qualification PCR test. Overall prevalence of HPV in tumour tissues was 81.17% in GP6+/GP5+ PCR, 40.58% by HPV16 and 49.41% for HPV18. The presence of HPV DNA in esophagus tumours (high risk HPV types 16 and 18) implicates HPV as one of the possible aetiology factors in esophageal carcinoma.","PeriodicalId":437476,"journal":{"name":"Journal of medical and bioengineering","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127149671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focused on the evaluation of the antiglycation effect of four Lamiaceae plants (Ocimum sanctum, O. basilicum, O. americanum and Metha cordifolia opiz.). Among the ethanolic extracts, O. sanctum extract exhibited high content of phenolic compounds and strong antioxidant activity. Chemical composition analyzed by HPLC revealing two major phenolic conpounds in O. sanctum extracts as rosmarinic acid (4.43 mg/g) and luteolin (0.96 mg/g). In the antiglycation assays, bovine serum albumin (BSA) and histone which were used as model proteins for investigation in the presence of methylglyoxal (MGO) with or without the extracts comparing with the authentic phenolic compounds. The results showed that O. sanctum extract possessed a potent antiglycation activity in both BSA and histone models with 23.4% and 43.0 % inhibition at the concentration of 500 and 250μg/mL, respectively. The results indicated that O. sanctum which contained high phenolic compounds has potential to prevent protein glycation caused by oxidative stress.","PeriodicalId":437476,"journal":{"name":"Journal of medical and bioengineering","volume":"229 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123307464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The OI has become a realized phenomenon of importance in the dental and rehabilitation sciences since recently developed dentures and artificial limbs are directly attached to human skeleton by using osseointegrated (OI) implants. Previously, the electricity-generating capability of bone had been investigated when it is subjected to mechanical loads. This is related to static and dynamic capability of bone, so-called linear piezoelectric and streaming potential effect respectively. Streaming potential or bone strain generated potential (SGP) is an electrical potential and considered to be generated by fluid flow in bone. Bone Piezoelectric potential (PZP) is an electrical potential and considered to be generated by deformation in bone. Since changes in boundaries on bone-implant affect deformations of bone matrix and interstitial bone fluid flow, it could be postulated that SGPZP could be used as a parameter to examine the amount of osseointegration on bone-implant interface. Since no study was performed to understand effects of loading rate changes on behavior of SGPZP for the bone-implant composite, rate dependent behavior of SGPZP was investigated in this study. Magnitude of SGPZP was found to be significantly increased as the rate increased for OI bone-implant composite. In contrast, the time duration of SGPZP was decreased as the rate increased. These results could imply that the temporal SGPZP behavior of bone-implant composite is significantly affected by the loading rate. ","PeriodicalId":437476,"journal":{"name":"Journal of medical and bioengineering","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121031911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
