The aim of this study is to examine the relationship between folic acid intake and spina bifida occulta prevalence in the Belentepe Byzantine population in Anatolian peninsula, and to compare the prevalence rates with various other ancient Anatolian populations by focusing on sacral spina bifida occulta in the Byzantine population. A total of 62 available human sacra were included in the study and compared with other sacra from relevant research using chi-squared test. Four male individuals had sacral spina bifida occulta with a prevalence rate of 6.45%, which is found to be lower in comparison to other ancient populations from western to eastern Anatolia. The present-day ecology of Belentepe indicates that foods rich with folic acid are common in and around the region. While some studies indicate the contrary, a comparison regarding the sacral spina bifida occulta prevalence with other populations in Anatolia shows a correlation between folic acid intake and proximity to a Mediterranean climate.</p>","PeriodicalId":46714,"journal":{"name":"Homo-Journal of Comparative Human Biology","volume":"71 3","pages":"175-188"},"PeriodicalIF":0.6,"publicationDate":"2020-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37729790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"社会学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present study used geometric morphometrics to assess variation of frontal bone morphology and its use in estimation of sex and ancestry. Frontal bones of 777 Black, Coloured and White South African adults were digitized and superimposed through Generalized Procrustes Analysis. Centroid sizes and morphological variation between groups were assessed. Accuracy of distinction between groups was assessed using Discriminant Function Analysis and leave-one-out cross-validation. Male frontal bones were more robust and sloped, compared to more gracile, rounded frontal profiles of females, resulting in classification accuracy of 79.3%. Morphological variation related to ancestry was found in the slope and width of the frontal bones, allowing distinction of the groups with 85.9% accuracy, even when including the heterogeneous Coloured group. When assessed according to sex and ancestry combined, 83.3% accuracy was achieved with the six sex-ancestry groups. These results show that variation in frontal bone morphology is sufficient to allow accurate distinction between these closely related groups, with accuracies compatible or exceeding those obtained when using the entire cranium of the same sample.

The studied sample consisted of 108 boys (4-15 years) from Huzhu County in Qinghai Province of China, which were divided into three groups: 4-6 years old, 7-11 years old and 12-15 years old. It was revealed that the landmark-groups of nose area were relatively long, indicating large variation in the direction of the nasal protuberance, which possibly reflected the vigorous growth of the children's nose. There were larger landmark-groups' variability ranges in children aged 7-11 years, which may be related to the rapid growth in this period. The average morphology of the sagittal plane of the face changed a lot with age, which was showed in the comparison of the averaged graph of three groups: (1) the proportion of the forehead to entire face became smaller; (2) the 7^th landmark extruded more noticeably; (3) the nose became protruding; (4) the position of the mouth was relatively getting more upward, and the angle formed between the upper lip and the lower lip increased, and the lower lip moved forward; (5) the chin protuberated. Principal Component Analysis (PCA) revealed significant differences in the main distribution areas between age group 4-6 years and 12-15 years, even though there was a lot of overlap in the three age groups. Allometric analysis showed that the sagittal plane of the face aged 4-6 years and 7-11 years changed in the following way as the size increased: the forehead became vertical and the upper lip turned to be smaller.

Some authors implied that frontal bone might be particularly affected by this condition due to specificity of its underlying dura.

Furthermore, in an attempt to test speculation of the possible role of estrogen in pathogenesis of HFI, we investigated the expression of α-estrogen receptors on dura of the frontal region. These analyses confirmed nuclear expression of estrogen on frontal region dural tissue, supporting previous speculation of the development mechanisms of HFI and contributing to a better understanding of this common condition of the frontal bone.

For this purpose, we have dissected 23 forearms and hands of fresh human cadavers of known sex and age at death, and dissected all the muscles attached at the first metacarpal (the first dorsal interosseous, opponens pollicis, and abductor pollicis longus muscles). Variations in physiological cross-sectional area, muscle mass, and fibre length were compared with metacarpal anatomy. In no case bone traits were a significant predictor of muscle features.
