Austropotamobius torrentium (Schrank, 1803) lives in two watercourses, namely Subotica (Sana) and Toplik (Tilava). The influence of the ecological conditions of these rivers on individuals of this species is analyzed based on 22 morphometric parameters. The assessment of abiotic conditions was done through the measurement of physical and chemical water parameters and the analysis of the composition of phytobenthos and macrozoobenthos. Sampling was carried out in June, September, and October 2021. Water quality at the investigated localities (on the basis of abiotic and biotic parameters) is oligo to betamesosaprobic. A total of 37 crayfish were analyzed (20 from Subotica and 17 from Toplik). Female crayfish have shown significant differences in the head width (HEW) and abdominal thickness (ABH). Males differed significantly in a number of parameters, including the weight (W), head shape (HEL and HEW), rostrum length (ROL), carapace width (CPW), and abdominal shape (ABH and ABL). Higher values of the indicated parameters have been found in the males from the Subotica River. The obtained results are influenced by different ecological conditions of their habitats. The Subotica River is a larger watercourse in the lowland belt with a large number of microhabitats, and the Toplik is a small river in the mountain belt, with uniform sediment and a small number of ecological niches of the analyzed species. The general ecological conditions in the water of both watercourses are also affected by aquaculture facilities, where wastewater has a direct influence on the distribution of Austropotamobius torrentium individuals in the watercourses of the Subotica and Toplik Rivers. For more detailed and complete data, it is necessary to analyze a larger number of individuals in both populations, and to include additional morphometric-meristic parameters and molecular-genetic analyses.

Background: Breast cancer in women is the second most common and accounts for approximately 18% of all malignant tumors in women worldwide. The etiology of breast cancer is not clear enough. Starting from the assumption that the manifestation of breast cancer may have a multifactorial model, this article compares the population-genetic structure of patients (experimental group) with the population-genetic structure of healthy population (control group). Objective: The aim of the study was to examine the possible genetic basis of the Rh factor relationship with selected homozygous-recessive traits of females with breast cancer, and to diagnose the probability (assess the risk) of developing the disease in healthy women by analyzing homozygous-recessive traits (HRT). Methods: This are an anthroposcopic-qualitative study that included two groups of subjects, experimental and control (a total of 80 subjects). An analysis of the percentages within each group was performed using the Chi-square test. The results are presented in tables, and the accepted level of significance is at the level of p <0.05. Results: In the group of Rh+ subjects, the correlation of this type of Rh factor with the breast cancer was proven, given the frequency of the phenotype of homozygous-recessive traits in them. A statistically significant difference was found for 4 traits, and three are also close to the set significance level. In subjects with Rh- factor, a statistically significant difference was found for only one trait (absence of mallets on the phalanges). Conclusion: Although the number of subjects was relatively small, we can conclude that in the experimental group a higher frequency of recessive phenotypes for the examined traits was recorded, which indicates the genetic load of the subjects from this group. Correlation with Rh factor was observed in the case of subjects of the experimental group with Rh+ factor.

BACKGROUND Piriform aperture is anterior opening of the nasal cavity formed by bones of the viscerocranium and knowledge about differences between genders is important for forensic scientists, anthropologists, orthopedists, neurosurgeons and vascular surgeons. The aim of this study was to examine gender differences of piriform aperture on 3D models of human skulls originating from Bosnian population using the geometric morphometric method. MATERIALS AND METHODS The study was conducted on 211 3D models of human skulls of known gender. 3D models were obtained by laser scanning. We analyzed the gender differences of piriform aperture using geometric morphometrics method. On 3D models we marked four landmarks on piriform aperture in the Landmark editor program, after which we analyzed its gender differences in MorphoJ program. RESULTS The first PCA axis described 40.398% of total variability of piriform aperture. The greatest gender variability was present in the position of the landmark rhinion. Discriminant functional analysis of the shape and size of the piriform aperture allowed the gender determination with 64.03% accuracy for male and 70.83% accuracy for female gender. The size of the piriform aperture showed a statistically significant difference between genders. Discriminant functional analysis of the shape of the piriform aperture without affecting size enabled gender determination with 59.71% accuracy for male and 62.5% accuracy for female. CONCLUSIONS Analysis showed statistically significant differences in the shape and size of piriform aperture between genders. The accuracy for gender determination based on piriform aperture was higher in females.

Aim To determine differences in quantitative traits of digital dermatoglyphics between breast cancer women and the women in the control group (healthy women). Methods This case-control study included digital dermatoglyphics of 50 patients with confirmed breast cancer diagnosis compared with 50 healthy examinees with the absence of familial history of any type of cancer. Collecting samples was performed among Bosnian-Herzegovinian population by Printake method. The comparison of the mean values between the examined groups was made by the Student's t-test and Mann-Whitney U test. Results The results showed that, with regards to the pattern intensity, no statistically significant difference was detected between the two examined groups (p>0.05).The absence of any significant difference in the number of papillary ridges on an individual finger between the breast cancer patients and the control group was found (p>0.05), although the total number of papillary ridges on all ten fingers had somewhat lower values in the examined group. Conclusion This research confirms the existence of genetic predisposition for breast cancer development, emphasizing the relevance of hereditary factors in the ethiopathogenesis of this disease. The quantitative traits of digital dermatoglyphics were not a reliable and predictive tool for detecting a potential risk for breast cancer in small populations.

Introduction: The main aim of the study was to examine the interdependence of values of the nutrition index, the use of medicaments, and alcohol consumption in the group of subjects with post-traumatic stress disorder (PTSD) and in control group without PTSD. Methods: To determine the interdependence of different indices of nutrition and the alcohol and drug consumption in both groups, the crosstab model was used. Results: In both of the tested groups, medicament users had higher average values for nutritional indexes compared to the subjects that are not the consumers of medicaments, but the confirmed differences were not statistically significant. The subjects with PTSD who consume alcohol had lower average values for nutritional indexes compared to the subjects who do not consume alcohol. In the control group, subjects who consumed alcohol had higher mean values for nutritional indexes than those who did not consume alcohol. Differences in the values of the nutrition index between alcohol and non-alcohol subjects were not statistically significant either in the PTSD group or in the control group. The subjects with PTSD had less average values of all the used nutrition indexes compared to the control group subjects, but the confirmed differences were not statistically significant. Conclusion: Our results indicate that medicaments use and alcohol consumption do not exert a statistically significant effect on the values of the nutrition index in any of the study groups. Possible concomitant use of drugs with the opposite effect on the monitored parameter (nitrazepam and amitriptyline vs. SSRI and bupropion) can lead to findings like this. We recommend further research to eliminate influence of pharmacodynamic effects of alcohol, drugs, and stress on the development of weight gain or loss.

Introduction: Malignant breast cancer is the most common malignancy in women between 40 and 55 years of age. Dermatoglyphs are polygenetically determined properties, whose appearance and number are determined by a specific gene. They represent the skin reefs that are created by epidermis on the fingers or toes, palms and soles. Palmar dermatoglyphs have been used to estimate the hereditary basis of many diseases. Aim: The aim of the paper is to determine whether there is a statistically significant difference between the observed qualitative and quantitative parameters of both palms between the experimental and the control group. Material and Methods: A survey of the qualitative and quantitative properties of the palmar complex was carried out on a total of 100 female respondents. The first group included 50 women with breast cancer. Comparative data were used for the analysis of palmar dermatoglyphs in the second group of respondents, or 50 phenotypic healthy female subjects. The imprints of the palmar complex were taken using the printake ribbons, analyzed, and the data was then statistically processed and displayed in charts. An analysis of the number of reefs between two digital triradius was performed, followed by the determination of the axially triad position, as well as the ATD angle measurement. Results: Quantitative analysis of ATD-angle showed statistically significant difference between the left and right palms of the analyzed groups. However, the analysis of the number of reefs between triradius A-B, B-C, C-D did not show statistically significant results for both the left and right hand between the analyzed groups. Conclusion: These results indicate that the quantitative palmar parameter, ATD-angle, can play a role in identifying women with increased risk of breast cancer.

Aim: The aim of this study was to investigate which is the most acceptable model for body mass index evaluation by a standard general pattern, since the one of the oldest bioantropological issues is what is the mass that a person should have, with a certain height, constitution, gender, age and other important determinants. Methods: This prospective study included 78 patients, male gender, divided into two groups: PTSD - group (44 patients) and control group (34 patients). Those were heterogeneous groups according to age and educational structure, where the 30's and 40's are dominant for age and high school education is dominant for education. Calculations of body mass index were performed using standard general pattern, applying different methodologies to obtain the theoretical mass values (Broca's, Azerad's, American insurance company's, Demelov's) Results: There are significant differences between the average values of body mass index calculated by the general standard pattern, depending on the different kind of calculation of theoretical mass used within the PTSD group  and control group.  Conclusion: The correlation coefficient indicates that nutritional index obtained by standard general pattern by use of different methodologies for determining a theoretical body mass is very similar for measurment and calculation of nutitinal state within the PTSD and control group. However, compared to correlation matrix we obtained within the PTSD group the coefficients of correlation  levels were slightly lower within the control group Kayword: body mass index, theoretical mass, PTSD

The Huchen is one of the most enigmatic species of Europe's freshwater fauna. Historically, the species was wide‐spread across the entire Danube basin. Since the late 19th century, however, Huchen populations declined by two thirds and the remaining populations are now highly endangered by hydropower development. In this study, we review the actual occurrence of Huchen in the Balkan region. A total of 1842 river km supporting self‐sustaining populations of Huchen in the region have been identified, making it the global hot spot for the species. These populations are found in 43 rivers or distinct river reaches in Slovenia, Croatia, BIH, Serbia and Montenegro. About 65% of all Huchen rivers globally are located in these countries, highlighting the importance of Balkan Rivers for the survival of the species. The major threat to these populations is a massive hydropower development plan. A total of 93 dam projects were identified directly in river reaches supporting Huchen and a large number of additional projects are located in tributaries or headwater reaches upstream of Huchen habitat that will invariably degrade environmental conditions downstream. If these plans are carried out, we predict that at least 60‐70% of the Balkan population and about 35‐ 40% of the global population of Huchen would be lost with the remaining populations being small and severely fragmented and eventually no longer able to survive in the long term.
