This study analyzes the risk assessment of Gachsaran petrochemical Ethan transformation 20 inch pipeline implementation design as one of the most important petrochemical designs of the country, with the knowledge of assuring necessity of proper and right implementation of projects and finally presenting solutions for adverse effects reduction on environment.

  VIKOR and ENVID methods are types of environmental risk identification methods that show necessary applicability for projects’ risk amount assessment.

In this research, relative analysis process of failure existence potentials is discussed and also sensitivity assessment and vulnerability detection of environment around us is done. This method conclude recognition of environment affected by gas leakage, important ecologic compartments checked and assessed considering environmental sensitivities, risk amount guaranty according to existing standards and identification of preventive actions and potential pipeline risk reduction actions.

The results show that in both mentioned methods, construction phase has more risk in comparison to application phase as in construction phase, physical and chemical and economical, social and cultural environments respectively get the most influence and in application phase with less severity comparing to construction phase Economical, social and cultural and physical and chemical receive the most influence.

Spontaneous abortion (SAb) is the most common complication of early pregnancy. Numerous risk factors are associated with an increased risk of pregnancy loss such as: Blighted ovum. The aim of this study was to determine the frequency of balanced chromosomal translocations in couples with a history of recurrent spontaneous abortions and ultrasound diagnosed blighted ovum. Sixty Eight couples with the history of spontaneous abortion (diagnosed blighted ovum) were selected and introduced into this survey during 2007-2012 at Medical Genetics department of Mashhad University of Medical Sciences. Giemsa banding technique was used to search for chromosomal balanced translocations. Demographic assessment has not shown any age difference between blighted ovum suffering couples and general population. Consanguineous marriages in blighted ovum suffering couples was significantly higher (P value <0.001) than non-consanguineous marriages (68.5% versus 31.5%), while in general population 62% of were non-consanguineous. The incidences of balanced chromosomal rearrangements as well as the rate of chromosome 9 inversion were 8.3 percent each, in non-consanguineous Blighted ovum suffering couples and the remaining (83.4%) showed normal karyotypes. There was no chromosome 9 inversion in consanguineous blighted ovum suffering couples and the incidence of balanced chromosomal rearrangements was 2.3%. With regard to relatively low incidence of balanced chromosomal rearrangements in consanguineous couples with blighted ovum, it would be reasonable to suggest that single gene determinants may play an important role in such pregnancy complications rather than chromosomal disorders.

In this study we performed linkage analysis on a large X linked RSA pedigree to find a novel susceptibility locus for RSA. A linkage scan using 11 microsatellites was performed in 27 members of a large pedigree of hereditary X-linked RSA. Two point parametric Linkage was performed using Superlink v 1.6 program. Evidence of linkage was observed to markers at Xq23, DXS7133 and at Xq22.1 DXS101, with LOD score of 3.12 and 1.60, respectively. Identified locus in this study may carry a responsible gene in RSA. Narrowing down of this region may leads to identification of this gene Recurrent spontaneous abortion (RSA) is one of the most common health complications with a strong genetic component. Several genetic disorders were identified as etiological factors of hereditary X linked RSA. However, more genetic factors remain to be identified.

IntroductionRelative differences in QOL between hemodialysis (HD) and peritoneal dialysis (PD) are not clearly known. The objective of this study was to compare QOL between HD and PD patients in Emam Reza and Ghaem hospital dialysis centers.Materials and MethodsWe compared 40 patients (17male and23 female) on PD with 40 matched patients (20 male and 20 female) on HD. Health related 36 item short form questionnaire (SF-36) were used to assess the quality of life. For the SF-36, eight domain scores (physical functioning [PF], role limitations as a result of physical problems [RP], body pain [BP], general health perceptions [GH], social functioning [SF], role limitations as a result of emotional problems [RE], vitality [VT], mental health [MH]) were calculated. We also calculated summary Physical Component (PCS), Mental Component (MCS) and total scores of QOL.ResultsThis study included 80 patients treated with HD and PD. The worst score was for RP dimension in both groups, and the best score was for RE in PD patients and BP in HD patients. SF-36 domains of GH, RP, VT and PCS were all significantly higher in the PD patients as compared to the HD patients. The only domain for which significant differences favoured HD patients was BP. (P < 0.05). ConclusionThis study provided evidence that patients in PD treatment modality were experiencing better quality of life in SF-36 domains of GH, RP, VT, PCS in comparison to HD patients
