The work is devoted to the development of a scientific and technical basis for instrument implementation of a digital diaphanoscopy technology for the diagnosis of maxillary sinus inflammatory diseases taking into account the anatomical features of patients (differences in skin structure, skull bone thickness, and sinus size), the optical properties of exercised tissues, and the age and gender characteristics of patients. The technology is based on visualization and analysis of scattering patterns of low-intensity radiation as it passes through the maxillary sinuses. The article presents the experimental data obtained using the digital diaphanoscopy method and the results of numerical simulation of the optical radiation passage through the study area. The experimental setup has been modernized through the installation of a a device for controlling the LED applicator brightness. The approach proposed may have considerable promise for creating diagnostic criteria for various pathological changes and can be used to assess the differences in the optical and anatomical features of males and females.

The palatine tonsils and the appendix are components of mucosa-associated lymphoid tissue (MALT), namely the peripheral part of the immune system, which provides a protective barrier of mucous membranes against foreign antigens. Topographic and anatomical unity of the lymphoid apparatus of the pharynx and abdominal organs determine their direct lymphatic connection. Despite the progress achieved in the study of the etiology and pathogenesis of chronic tonsillitis and the pathology of the appendix, surgical treatment of these diseases remains the main one. The question of the influence of tonsillectomy and appendectomy on the state of humoral immunity remains controversial. The mechanisms of interaction of various links of humoral immunity in the formation of conjugated diseases of the lymphoid apparatus of the pharynx and abdominal cavity, namely, the palatine tonsils and the appendix, as well as statistical, clinical, immunological and morphological indicators concerning 940 patients with acute appendicitis at the age from 3 to 18 years old, who were undergoing treatment at the Kruglaya Multidisciplinary Center for the period from 2015 to 2018. The analysis of the statistical, seasonal, age and gender characteristics of the prevalence of acute appendicitis (AA), suggesting a connection with infectious and inflammatory diseases of the pharynx. Clinical cases showing the combination of tonsillar pathology and AA are presented. Based on the data obtained, similar immune-morphological changes in the palatine tonsils and the appendix were revealed during their inflammation, and the possible immune mechanisms of the pathogenesis of AA in tonsillar pathology were substantiated. Keywords: acute and chronic tonsillitis, complications, appendicitis.

Introduction: Computer Tomography (CT) scans can deliver a relatively high radiation dose to the patient, therefore radiation protection for this modality is paramount. The present study determined the frequency of no abnormality detected (NAD) brain CT scans and probability of cancer induction in different age groups and genders. Methods: In this study, brain CT reports were used to identify any findings as abnormality detected (AD) and others as NAD. Then probability of future leukemia and brain cancer was estimated for different age and gender groups. Results: On average, in 65% of the cases the results were NAD (56% and 76% among males and females, respectively). Among children, 79% of the reports were NAD. The total number of projected brain cancers was 1.8 and 1.3 for males and females, respectively. The number of projected leukemia cases was 0.75 and 0.7 for males and females, respectively. For pediatric patients, brain CT scans can lead to leukemia cases about 4.5 times more often than adults. Conclusion: Brain CT scans can lead to additional cases of brain cancer and leukemia. A significant fraction of brain CTs were NAD (non-pathologic) and could practically be replaced by other radiation-free imaging modalities, especially in pediatric and young patients.

The Relationship

This article studies the cognitive features of the “power” frame and its gender implementation in the historical tragedy by W. Shakespeare “Macbeth”. Here, the author examines the concepts of “frame” and “gender” in linguistics, studying different approaches to their definition. The relevance of this work is determined by the close attention of the contemporary linguistics to these concepts, as well as their place in the contemporary academic paradigm. The academic affirmation of the “frame” and “gender” concepts designates a new step in understanding the ways and peculiarities of the language interaction, consciousness, and culture, and, consequently, it shows new aspects of the relationship of linguistics with other sciences. Nevertheless, the problems of both frame and gender are not yet fully understood. This study allows describing in detail the essence of the frame “power” and showing its meaning, use, and ways of its gender implementation in fiction, which explains the novelty of this article. The study’s methodology is based on the cognitive-discursive analysis of the text, as well as on an integrative approach to the discourse study, which combines methods of both cognitive and gender linguistics, as well as the discourse analysis. Common research methods were used along with private linguistic methods. The application of cognitive-discursive analysis has significantly increased the depth of understanding of the “power” frame that dominates Shakespeare’s historical tragedy. This historical text presents the central theme of political tragedy: the overthrow of the rightful ruler and the usurpation of power. The motive for the seizure of power forms a thematic core and is presented from the usurpers’ point of view. In this article, the author observes the gender shift and duality of the female and male beginnings: Shakespeare puts the female protagonist, hungry for power, among men, thus the images of Lady Macbeth and her husband come into conflict with the gender characteristics attributed to them. The play clearly traces the main idea of Machiavellianism: the goal justifies the means. The results conclude that the “power” frame is the leading one in Lady Macbeth’s monologue, thus setting one of the main themes of this tragedy.

ABSTRACTObjectives: The aim of this study is to determine retrospectively the presence of carotid artery calcifications (CACs) detected on panoramic radiographs (PRs) in a group of Turkish population. Further, the relationships between CACs and gender, life style, and medical history were evaluated.Methods:During the years 2004 to 2006, a random sample of 1282 PRs was collected from patients older than 40 years who were being treated by the School of Dentistry, Erciyes University. Of these 1282 PRs, 750 PRs were included in this study. Medical data was collected from the archival records of the dental school.Results: About 38 (5.06%) CACs were found on the PRs of 12 (4.5%) males and 26 (5.4%) females. The CAC prevalence was not significantly different between the males and females (P=0.583). These calcifications were unilateral in 26 (68.4%) and bilateral in 12 (31.6%) subjects. Of those in the positive group, there were 12 subjects (31.58%) with hyperlipidemia, 12 subjects (31.58%) with hypertension, 7 subjects (18.4%) with diabetes mellitus, 6 subjects (15.8%) with cardiovascular disease, and 6 subjects (15.8%) with smoking history.Conclusions: This study has the highest CACs prevalence in comparison to the other studies. Therefore, dentists caring for subjects with dental problems should carefully evaluate their PRs for the evidence of CACs, and refer them for medical evaluation as indicated. So, incidental findings could provide life-saving information. (Eur J Dent 2007;1:132-138)

Melanotic Encapsulation

A few studies have shown that male and female invertebrates differ in immunity and that these differences appear related to differences in sexual dimorphism and gender differences in life histories. Melanotic encapsulation of foreign objects in insects is one form of immunity. The damselfly Lestes forcipatus Rambur is moderately sexually dimorphic, and much is known about patterns of mass gain in congeners relating to differences in life history between males and females. In this study, females were more immunoresponsive than males under controlled temperatures, following emergence, and at a time when parasitic mites were challenging these hosts. However, males and females that overlapped in mass at emergence did not differ in their immune responses. Males in better condition at emergence were more immunoresponsive than lighter males, but this relation was not found in females. Sex differences in immune expression may have implications for how females versus males are able to deal with challenges from parasites, under varying environmental conditions.

This study uses data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) project to assess the relationships between childhood physical abuse/sexual abuse and adolescent substance use. Whether these relationships are mediated by externalizing problems, internalizing problems, parent–child attachment, or anger and gender differences in these direct and indirect relationships is also addressed. Results indicate that there is a direct relationship between physical abuse and substance use and that mediating pathways between maltreatment and substance use are different for males and females. These results suggest that gender-responsive services should be provided to prevent and address adolescent substance use.

The aim of this study was to reveal and to describe the structure of the verbalized concept of «flirting». The main method of the research was a psycholinguistic experiment. The sample comprised 400 young people (aged 18-35), males and females being equally represented. The concept of «flirting» is represented by eleven clusters, four of them are core: «verbal and non-verbal ways of communication», «forms and ways of interaction», «emotions, feelings, states», and «gender». Two psycholinguistic meanings of «flirting» concept were described: «The stage of courtship with no intimate relation», «Sexual relationship». The semantic content of the concept of «flirting» does not depend on gender identification. The general attitude of the respondents to the stimulus «lightness» is quite positive.

The purpose of the work is to determine in the Ukrainian society the scale of harm inflicted by drinkers to other persons, as well as the gender and age characteristics of this harm. In four regions of Ukraine (Kharkiv, Lugansk and Zaporizhzhia regions, Kyiv), during 2018-2020, 1,742 people were examined from three qualitatively different comparison groups: patients with alcohol dependence (393 people); their healthy relatives (274 people) and representatives of the general population (1075 people). The main research tool was the questionnaire of the international research consortium GENAHTO (Gender, Alcohol, and Harms to Others). It was shown that, in general, drinkers are present in the microsocial environment of 27.62 % of the surveyed healthy respondents. Extrapolation of this indicator to the entire population of Ukraine suggests that the total number of people who suffer in one way or another due to the drinkers in their environment is about 11.6 million people. In addition, the drinkers frequency in the environment of respondents can be used to determine the real number of people with alcohol problems in our country. Preliminary calculations indicate that this number is from 1.5 to 2.2 million people. The drinkers frequency in the environment of the respondents significantly depends on the age of the latter. The highest values of this indicator are characteristic of the respondents in the age category 40—59 years old” (31.43 % for men and 41.27 % for women). The subjective perception of harm from drinkers in the environment grows steadily with increasing age of the respondents, while this growth is most pronounced in women.
