Relevance. Separate issues in anthropomorphic sizes of relative norm of the ideal smile, its qualitative and qualitative parameters have not been addressed to sufficiently and are not properly reflected in scientific literature.Purpose. To determine distinguishing features in average smile parameters of the smile in male and female patients with orthognathic occlusion.Materials and methods. A clinical and anthropometric evaluation of parameters in main smile types was carried out for 150 young males and 150 young females aged 19-24 who had identical physiological development parameters.Results. It has been revealed that occurrence frequency of main smile types in patients with orthognathic occlusion has pronounced signs of sexual dimorphism which in over one half of the cases lies in predominance of the incisal smile type in males (52.7%) and the fascial type in females (55.3%). Occurence frequency of the cervical smile type totaled 25% among the studied patients of both genders. Average vertical size parameters in the incisal smile lies within the diapason of 3.91-4.91mm with surpassing by 1mm in males. Analogical data for the fascial smile type form the diapason of 6.21-6.73mm with surpassing by 0.52mm in females. The cervical smile type is characterised by larger vertical size forming the diapason of 7.94-8.91mm with surpassing by 0.97mm in males.Conclusion. The results of the study have shown that the “beautiful and ideal smile” is a relative concept having varied anthropometric characteristics and pronounced signs of sexual dimorphism lying in a broad spectrum of the dentofacial system norm notion with specific vectors for individual morphological deviations.

The eclectus parrot (Eclectus roratus) is a species of parrot native to the Solomon Islands, Sumba, New Guinea and nearby islands, northeastern Australia, and the Moluccan Islands. The wide range of behaviors emphasizes the existence of knowledge of only a mere fraction of the significant behavioral parameters of these birds. The objective of this study is to identify the behavior of the eclectus parrot kept in captivity and to check the frequency of these birds in certain places of the nursery, comparing the results to other studies about parrots and the behavior in nature. This is a study about the behavior of a bird with a very pronounced sexual dimorphism, where the males have a predominantly green color, and the females are mainly red-colored. In the wild, while the male perches on the outer branches of the trees, the female usually perches close to tree trunks. This location, together with her red and blue plumage, provides the ideal camouflage in the dark interior of the trees.

Abstract This paper investigates whether the gender and/or age of interviewees in dyadic interviews influences frequency of speech interruption of young female interviewers. Forty female students at King Faisal University (KFU) and forty interviewees participated in the study. The author compared the number of interruptions per ten minutes of conversation made by interviewees belonging to four categories: young females, young males, older females, and older males. The author hypothesized that older male interviewees interrupt young female interviewers more than younger male and female interviewees. Additionally, the author hypothesized that older female interviewees interrupt young female interviewers more than young female interviewees. The results did not support the hypothesis that males interrupt females more often. Female participants made significantly more interruptions than male participants. The data do not support the hypothesis that older interviewees interrupt their interviewers more frequently than younger interviewees.

AbstractThe liver is one of the most sexually dimorphic organs. The hepatic metabolic pathways that are subject to sexual dimorphism include xenobiotic, amino acid and lipid metabolism. Non-alcoholic fatty liver disease and hepatocellular carcinoma are among diseases with sex-dependent prevalence, progression and outcome. Although male and female livers differ in their abilities to metabolize foreign compounds, including drugs, sex-dependent treatment and pharmacological dynamics are rarely applied in all relevant cases. Therefore, it is important to consider hepatic sexual dimorphism when developing new treatment strategies and to understand the underlying mechanisms in model systems. We isolated primary hepatocytes from male and female C57BL6/N mice and examined the sex-dependent transcriptome, proteome and extracellular metabolome parameters in the course of culturing them for 96 h. The sex-specific gene expression of the general xenobiotic pathway altered and the female-specific expression of Cyp2b13 and Cyp2b9 was significantly reduced during culture. Sex-dependent differences of several signaling pathways increased, including genes related to serotonin and melatonin degradation. Furthermore, the ratios of male and female gene expression were inversed for other pathways, such as amino acid degradation, beta-oxidation, androgen signaling and hepatic steatosis. Because the primary hepatocytes were cultivated without the influence of known regulators of sexual dimorphism, these results suggest currently unknown modulatory mechanisms of sexual dimorphism in vitro. The large sex-dependent differences in the regulation and dynamics of drug metabolism observed during cultivation can have an immense influence on the evaluation of pharmacodynamic processes when conducting initial preclinical trials to investigate potential new drugs.

Abstract Background The efficient management of relational competences in healthcare professionals is crucial to ensuring that a patient’s treatment and care process is conducted positively. Empathy is a major component of the relational skills expected of health professionals. Knowledge of undergraduate healthcare students’ empathic abilities is important for educators in designing specific and efficient educational programmes aimed at supporting or enhancing such competences. In this study, we measured first-year undergraduate nursing students’ attitudes towards professional empathy in clinical encounters. The students’ motivations for entering nursing education were also evaluated. This study takes a multi-method approach based on the use of qualitative and quantitative tools to examine the association between students’ positive attitudes towards the value of empathy in health professionals and their prosocial and altruistic motivations in choosing to engage in nursing studies. Methods A multi-method study was performed with 77 first-year nursing students. The Jefferson Scale of Empathy (JSE) – Health Professions Student Version was administered. Students’ motivations for choosing nursing studies were detected through an open question and thematically analysed. Using explorative factor analysis and principal component analysis, a dimensional reduction was conducted to identify subjects with prosocial and altruistic motivations. Finally, linear models were tested to examine specific associations between motivation and empathy. Results Seven distinct themes distinguishing internal and external motivational factors were identified through a thematic analysis of students’ answers regarding their decision to enter a nursing degree course. Female students gained higher scores on the empathy scale than male ones. When students’ age was considered, this difference was only observed for younger students, with young females’ total scores being higher than young males'. High empathy scores were positively associated with altruistic motivational factors. A negative correlation was found between external motivational factors and the scores of the Compassionate Care subscale of the JSE. Conclusions Knowing the level of nursing students’ empathy and their motivational factors for entering nursing studies is important for educators to implement training paths that enhance students’ relational attitudes and skills and promote the positive motivational aspects that are central to this profession.

Chlamydial Infections

Summary: Nine genitourinary clinics (one teaching hospital and 8 district general hospitals) within the Yorkshire Deanery audited the management of uncomplicated genital chlamydial infections in male and female patients attending between January and December 1995. Standards set included: 100% of chlamydia-positive patients to be treated within 2 weeks of diagnosis; 100% of patients to return for test of cure within one month of treatment; 100% of patients to be referred for contact tracing. Four hundred and thirty-six of a total 1356 cases were audited. Eighty-nine per cent received treatment within 2 weeks; 64% returned for a test of cure within one month; 93% were referred for contact tracing. Changes in practice and a regionwide multidisciplinary audit initiative resulted from the study.
