Geochemical investigation of oil seepages and Paleozoic sediments for determining probable source rock in the Bandar Abbas Hinterland

A remarkable characteristic of the Bandar Abbas Hinterland is the frequent presence of oil seepages that can serve as an indicator of probable oilfields in the region. The Seeps A and B are located in the main Zagros Suture Zone, 150 km to the northeast of Bandar Abbas and 30 km to the west of the same city, respectively. The presence of well-known Paleozoic source rocks (e.g., Seyahou, Sarchahan, and Gurpi formations) in the vicinity of the mentioned oil seepages shows that the seeping oil is coming from an oil source. The present research is aimed investigating the petroleum system and determining the source of the mentioned oil seepages. Results of the Rock-Eval analyses showed that the samples of the Seyahou Formation are thermally overmatured, making them exhibit inadequate oil generation potential. These samples contain Type-III kerogen and were found to be in the metagenesis stage. However, compared to other formations, Sarchahan and Gurpi exhibited good hydrocarbon generation potentials. On the other hand, based on the PI – Tmax diagram, the Sarchahan Formation was found to be in the early oil and condensate production window (i.e., catagenesis stage) while the Gurpi Formation was seen to be immature. Biomarker analysis results showed that the samples were deposited in a mixed marine environment and contained Type-II and Type II/III kerogen. The reason behind the occurrence of the oil seepages in an oxidative environment could be the sever impact of the biological degradation. The stable carbon isotope composition of the crude samples supported the biomarker data in general. Therefore, it can be concluded that the studied oil seepages were probably sourced from the Sarchahan Formation

Epidemiologic study of hymen situation in persons referred to examination part of Shiraz legal medicine organization

Background : Hymen examination has divers individual, family, social and legal effects. Thus epidemiology of hymen for physicians and obstetricians is important. Materials and Methods: In an analytical cross-sectional study of women referred to women's forensic medical examination part of Shiraz from 2008 to 2009 were examined. Results: A total of 823 samples with a mean age of 21.78±2.98 years and 16-20 years old were the most frequent age group among the cases. 53.58% of hymens were dilated circular and 46.17% of them were non dilated circular and 2 had no hole.From view point of anatomical type, 86.99% were in dilated circular hymens with smooth edges and the most frequent time of defloration of 80.33% of the cases was 3 weeks before examination. A significant relationship was observed between age and health status of the hymen. Also the relationship between age and time of defloration was significant. Conclusion: There is a variety in anatomical shape of hymen ,and distinguishing normal findings from abnormal findings in the examination of hymen is a matter of importance

Demographic Evaluation of Oro-Dental Self-Injury for Insurance Deception; Evaluation of the Cases Referred to Shiraz Forensic Medicine Center

Statement of the Problem: Nonsuicidal self-inflicted injuries are socially unacceptable and may cause mild to severe damages. Purpose: This study aimed to evaluate the demographic features of the subjects with orodental self-injuries referred to a forensic medicine center in Shiraz, Iran. Materials and Method: This cross-sectional study evaluated 51 participants (49 men and 2 women) with orodental injuries referred to forensic medicine administration. Orodental self-injury was detected in the subjects, based on the last forensic criterion of self-injuries, considering their history, clinical examinations, and panoramic radiographs. Results: The findings of this study revealed that dental self-injuries were more prevalent among married men from urban areas with secondary education levels. Most of the cases were due to the monetary compensation received. In the majority of cases, a hard object was used for this self-injury. Moreover, no statistical association was observed between the economic status and orodental self-injury. Conclusion: This study concluded that dental self-injury could be regarded as an unplanned incident because no significant correlation was observed between the participants, their economic status, and the type of dental trauma. Furthermore, detailed investigations on the latent variables are required

A seven-year study about the epidemiology of smoking, alcohol, drugs and psychotropic consumption along with legal abortion in cases referred to forensic medicine centers in Fars since 2007-2013

Introduction: Smoking, alcohol, and drugs consumption has increased among the women of child-bearing age. This rise and its negative consequences on the children's health have been considered by planners and WHO health centers. This study aimed to examine the prevalence of smoking, alcohol and drugs consumption among women of childbearing age who received abortion permission with either maternal or fetal causes from forensic medicine centers. Method: This is a descriptive-analytical study which was conducted during the years 2007- 2013. The total sample size was 1,664, of which 339 and 1325 had maternal and fetal abortion causes, respectively. The items registered in the questionnaire included demographic and obstetric variables, maternal or fetal causes of abortion, the simultaneous use of hookah and cigarettes, alcohol, psychotropic substances and drugs. The data were analyzed using descriptive statistics in SPSS software, version 11.5. Results: The most frequent age for women was between 25 and 30 years (31.5%). The legal abortion rate was 8.5% among women aged under 20 years old. The prevalence of substance consumption was 40.7% among women with either maternal or fetal cause abortion. It was estimated that 78.3% belonged to cigarette and hookah, 14.62% to drug and psychotropic and finally 5.31% to alcohol beverage consumption. Conclusion: In Iran, legal abortion approval is either by maternal or fetal causes. According to this study, the coincidence of pregnancy with cigarette and hookah consumption has the most prevalence. Substance abuse prevention, treatment, and control policy are one of the essential matters related to the care both before and during pregnancy
