Associations of sexual behavioral aspects and sexual scripts among college students: A cross-sectional study

Background: Sexual scripts (SSs) are formed based on the gendered culture in societies. Objective: To evaluate the associations between the sexual behavioral aspects: capacity, motivation, performance, and SS amongst Iranian college students. Materials and Methods: From September 2020 to December 2020, we recruited 400 college students who were married, had no acute or chronic diseases, was no drug abuser, and were not pregnant at the time of the study. The demographic questionnaire, sexual behavior assessment, and SSs questionnaires were completed by all the participants. Descriptive statistics and inferential statistics, Pearson correlation coefficient, and multivariate regression were used for data analysis. We also employed an independent t test to compare sexual behavior-related variables: sexual capacity, sexual performance, sexual motivation, and SSs in 2 female and male student groups. Results: Men and women were significantly different in the component of sexual behaviors. Women had higher sexual motivation than men. The participants’ SSs were positively correlated with all 3 components of sexual behaviors at a significant level of p ≤ 0.001. Of demographic characteristics, only women’s age had a significant correlation with sexual capacity. For men, education level and economic status were positively correlated with all components of men’s sexual behaviors. Conclusion: Sexual behaviors seem to be highly gendered, particularly, in the motivational component. Based on the results, SSs are more determinant than demographics. We recommend gender-sensitive and cultural-oriented sexuality educations for Iranians to provide fundamental changes in the SSs.

(2,2′-Dimethyl-4,4′-bi-1,3-thia­zole-κ2 N,N′)diiodidomercury(II)

In the title compound, [HgI2(C8H8N2S2)], the HgII atom is four-coordinated in a distorted tetra­hedral geometry by two N atoms from a 2,2′-dimethyl-4,4′-bithia­zole ligand and two I atoms. In the crystal structure, adjacent mol­ecules are connected by π–π contacts between the thia­zole rings [centroid–centroid distance = 3.591 (3) Å]

Phylogenetic relationship and genetic differentiation of Populus caspica and Populus alba using cpDNA and ITS noncoding sequences

Populus caspica Bornm. (section Leuce and subsection Albida), one of the most endangered endemic tree species in the Hyrcanian Forest in Iran, has numerous morphological characteristics that are closely similar to Populus alba; to clarify their taxonomic relatedness and genetic differentiation and thus inform conservation strategies, we used the noncoding regions of chloroplast DNA (cpDNA; trnL-F and trnH-psbA) and the internal transcribed spacer (ITS). Leaf samples were collected from six populations across northern Iran. cpDNA and ITS fragments were amplified by universal primers using the PCR technique and directed sequencing. The results showed that P. caspica is genetically differentiated from P. alba, and two ITS variants were detected within some P. caspica individuals. Conflicts between topologies from ITS and plastid genomes were observed. High differentiation of P. caspica from the other Populus species shown in this study confirmed the diverging taxonomic status of this endangered species. We recommend in situ conservation measures (e.g., protected areas) for at least several populations of this species, especially in the plain regions of the Hyrcanian forest

A case of Thrombotic Thrombocytopenic Purpura following the AstraZeneca Vaccine

A severe acute respiratory syndrome caused by coronavirus 2 infection (COVID-19)was identified in December 2019 and caused a massive pandemic that claimed millions of lives worldwide. The Chimpanzee adenovirus vector vaccine is one of the few vaccines against coronavirus disease in 2020. This case report introduces, a patient who developed thrombocytopenia, fever, and lethargy nine days after vaccination with the chimpanzee adenovirus carrier vaccine. The patient was admitted to the hospital and thrombotic thrombocytopenic purpura (TTP) symptoms appeared during hospitalization
