The aim is to evaluate the eruption of permanent teeth in Bulgarian children aged 5–12 years and to assess its relationship with age and sex. The present cross-sectional study included 709 individuals from 5 to 12 years. The oral and dental status was checked and included the number of erupted teeth (NET). Statistical analyses were performed to compare the sexes and ages. Statistically significant differences between sexes are observed only in teeth 17, 27, 33 and 43. The sequence of tooth eruption was examined, and it is almost identical in male and female subadults. Mandibular teeth erupt earlier than maxillary teeth, excluding first premolars for both sexes and canines in males. Females have earlier tooth eruption and more permanent teeth compared to males. A significant association between age and NET is established. Sex does not have a significant effect on tooth eruption. The time of eruption of permanent teeth is influenced significantly by age, but not by sex in our sample. Differences between males and females are found in the sequence of eruption only of canines and premolars. Females tend to have earlier tooth eruption and more erupted teeth. Lower teeth erupt earlier than upper teeth, excluding first premolars in both sexes and canines in males.

However, scholars are not unanimous on whether menopause enhances the CVD risk, independent of the normal process of aging and other confounding factors. Despite the cardio-protective effect of endogenous estrogen during their premenopausal years, the increased life expectancy of women exposes them to a greater lifetime risk of CVD compared to men. The aim of the present study was to understand the cardiovascular risk factors associated with different stages of menopause. This study was cross-sectional in nature and was carried out in the Howrah district of West Bengal, India. Two hundred and one participants were recruited for the study (Premenopausal 71, Perimenopausal 61, and Postmenopausal 69). Data on body fat distribution, blood glucose levels, and total cholesterol, blood pressure, and socio-demographic, menstrual and reproductive history, and lifestyle characteristics were obtained following standard protocols. Multivariate analysis of covariance was performed to understand how menopausal status impacted CVD risk factors after controlling the effects of the confounders. Menopausal status significantly predicted the CVD risk factors and body fat measures after removing the effects of the confounding variables, reinforcing the role of estrogen in the development of CVD. An overwhelming majority of the participants in our study have central obesity; so, this group is more prone to developing CVD in the near future. Future cross-cultural studies are required to understand how the link between menopause and CVD varies across different cultural groups and throughout the menopausal transition.

A Geometric Morphometrics Approach to Study the Biological History of Early Human Peopling of the Island Lauria, Gabriele; Sineo, Luca In recent years, the debate about the early human peopling of Sicily has almost exclusively focused on the archaeological evidence. The dispersal patterns and the possibility for, and degree of, admixture caused by ancient migratory flows have been only investigated in limited anthropological studies conducted on a short time spans. Recent craniofacial morphometric analyses that considered migratory flows and population influx have provided a more comprehensive approach. These analyses go beyond archaeologically based settlement hypotheses by merging previous archaeological evaluations and paleoclimatic studies with an anthropological approach. This study expands upon earlier morphometric work and provides an overview covering the period from the Upper Palaeolithic to the Iron Age. For this study, human skulls from Sicilian Prehistory and Protohistory were considered. These skulls were divided into six periods based on the dating of associated archaeological artifacts. Sample selection was based on a detailed bibliographic review of previously published archaeological and historical works. With the aim of associating the diachronic changes in cranial morphology with population migrations and admixture we performed a 3D geometric morphometrics (GM) comparative analysis. The data reported demonstrate that the first colonization of Sicily started during the Upper–Paleolithic when stable climatic conditions allowed hunter-gatherers to move from the Italian Peninsula to the island. Moreover, the results show a cyclical occupation of the land counterclockwise direction completed only with the hinterland colonization in the first historical periods with Greek and Punic colonization.

Those who prefer long-term relationships have restricted SO, and those who pursue short-term relationships have an unrestricted SO. Sociosexuality may be assessed by Sociosexual Orientation Inventory (SOI-R). Here, we test a new method to assess SO. Respondents are asked to create a personal ad by selecting six out of 10 suggested preferred traits in a partner. Among these 10 traits, there were two traits in each of five evolutionary relevant categories i.e., attractiveness, commitment, resources, cognitive and social skills. We hypothesize that seeking attractiveness/sensuality in a potential partner is related to concentrating on mating investments (higher SOI-R) and to commitment to parental investment (lower SOI-R). Out of 416 subjects who participated in the study, 299 (188 women) were included in the analysis. We found that choosing two traits of attractiveness is related to a less restricted SO, while preference for two commitment traits category characterizes those with a more restrictive SO. No relationship between SOI-R and the preference for cognitive skills or resources was found. Women with more and men with less restricted SO sought partners with better social skills. The proposed new method could be used to assess reproductive strategy. Wed, 16 Apr 2025 00:00:00 GMT http://hdl.handle.net/11089/55845 2025-04-16T00:00:00Z
