The aim of the study was to assess whether the body build has an impact on hand grip strength, muscle endurance and time reaction in children. The material of the research were 376 children from 6.78 to 11.82 years old in 2018. Body weight, height, waist, hip and mid-upper-arm circumferences, triceps and subscapular folds were measured. The BMI, body fat and AHtR (arm-circumference-to-height ratio) were calculated. The hand grip strength, simple reaction time (Quickstick) and strength of the abdominal muscles (endurance) were tested. Two-way ANOVA and correlation analyses with significance level p < 0.05 were used. Children with normal BMI values are characterized by better simple reaction time than their obese peers, while overweight and obese children estimated on the basis of BMI, AHtR and body fat perform were better in hand grip strength. In the case of strength of the abdominal muscles, there were no differences in children with different body build. The normal build and body weight promotes the proper development of children, which also is reflected in the results of motor performance and fitness tests.

The skeletons investigated herein were dated to the Late Eastern Roman Period, at the time of the golden age under the reign of the Macedonian dynasty ruled between 867 and 1056. In the Kütahya region, which acted as a border and frequently changed between the Eastern Roman and Seljuk states, the oral and dental health of the Attepe and Dereköy populations in this period was differed proportionally. A dam was constructed in Kütahya Province near Kureyşler Village for irrigation purposes. The Attepe settlement (AD 986-1050) and Dereköy necropolis (AD 966-1032) are located within the boundaries of the dam lake. To save the cultural assets in these areas, excavation studies were conducted by the Kütahya Museum in the region in 2014. This study investigated 447 permanent teeth from 34 adult individuals in the Attepe population, and 270 permanent teeth from 17 adult individuals in the Dereköy population dated to the Late Eastern Roman period. When the distribution of dental diseases in the Attepe population was examined, it was determined that 13.77% had caries, 0.81% had periapical lesions, 68.18% had periodontal disease, 13.07% had calculus, 17.98% had hypoplasia, and 22.33% had antemortem tooth loss (AMTL). In the Dereköy population, 12.88% had caries, 2.01% had periapical lesions, 80% had periodontal disease, 3.83% had calculus, 23.28% had hypoplasia, and 5.37% had AMTL. In both populations, the degree of tooth wear was determined as grade 3 and 4. The dental data showed that agricultural-dominated nutrition consumption was effective in the Attepe and Dereköy populations. In both populations, there were significant differences between the amount of caries and calculus (p = 0.00 < 0.05) as well as tooth wear and calculus (p = 0.00 < 0.05). When all these findings were assessed in an integrated fashion, it was possible to understand the features of a village population being involved in agriculture and dominant stock farming in a region in western Anatolia during the 10^th-11^th centuries, which coped, for the most part, with epidemics and infectious diseases, wars, and perhaps periodic famines.

The present investigation comprises the characterization of skeletal remains recovered from the 2004 archaeological excavations carried out in the Cloister's Southwest Wing of the Academy of Sciences of Lisbon, attributed to the 1755 earthquake. Among the remains, many teeth were found. Our goal is to use dental morphological characteristics to assess the geographic ancestry of the combined sample using the methods of biodistance and web-based application of the Arizona State University Dental Anthropology System 2. The crown and root traits of the ASUDAS were scored in a sample of 1068 disarticulated teeth, 65 skulls, 138 adult and 42 sub-adult jaws. Eight characteristics of 34 specimens (7 skulls and 27 jaws) were analyzed using rASUDAS2. Results demonstrate that 73.5% of this sample can be assigned to Western Eurasian ancestry, with the remaining 26.5% divided between Sub-Saharan Africa, non-Arctic and Arctic America, and East Asia. Euclidean and Bray-Curtis distance measures were used to put this Portuguese sample in a world context. From both distance matrixes, cluster analyses were used to generate dendrograms. Based on Bray-Curtis values, Portugal is closest to Western Europe, followed by India and Eastern Europe. For the tree based on Euclidean distances, India is the first to join Portugal, followed by Eastern and Western Europe. Therefore, on both an individual and group level, the Portuguese sample is most closely tied to Western Eurasia. However, there may be other ancestries in the sample, such as Sub-Saharan Africa, due to non-European migrants in Portugal along with the African slave trade to Brazil that reached its peak in 18^th century Lisbon.

The study describes the pathological findings recorded on the human remains of a 3 to 4-year-old child found in the burial site of Trutmanice (Czech Republic), dated to the 13^th-15^th century. The human remains were examined using standard macroscopic osteological and paleopathological methods, supplemented by radiographic examination. Although the preservation of the bones limited the analysis, multiple pathological changes were observed mainly on the skull: cribra orbitalia, small pores and fine deposits of newly formed bone tissue, hypertrophic diploë, grooves indicating rich branching of meningeal arteries on the intracranial surface of the cranial vault. A very fine periostotic deposition of newly formed bone tissue was also observed at the distal end of the diaphysis of the right tibia and both distal ends of the femora. The radiographs of the femora showed white lines of Frankel, scurvy lines, and Wimberger's rings. The observed pathological changes were possibly consistent with scurvy based on differential diagnosis. Reports about cases of juvenile scurvy from rural areas within the context of landlocked countries of Central Europe are rare. While scurvy is now more frequently reported in the paleopathological literature, evidence for scurvy within one of the most natural agricultural areas in the Czech lands remains rare. We recommend using radiographic examination to complement the diagnosis of scurvy in future paleopathological and epidemiological studies of past populations.

Alfredo Salafia, an Italian embalmer who was active in the early 20^th century, treated a number of corpses with his own preservation method. Among them was the young Rosalia Lombardo, just shy of two years old at the time of her death, whose remarkable preservation has brought her significant attention. It is well documented that Salafia had concocted a formula for a highly advanced embalming fluid which is believed to have been used to preserve Lombardo. This is referenced in a book and in two unpublished documents, and was also traced through familial memories and stories within the Capuchin Brotherhood of Palermo, where three of those bodies embalmed by Salafia are kept in a world-renowned crypt. Salafia's paternity of this specific preparation is further supported by some indirect evidence, which corresponds to what the embalmer described in his handwritten memoir. A recent article by Galassi and co-workers, however, attempted to debunk Salafia's role, and questioned the results of previous research performed on this case. They suggest additional studies on Lombardo that are not only unnecessary, but would irreversibly damage the long-term conservation of the mummy. Our paper aims to demonstrate that their article is biased and built upon incorrect assumptions and interpretations, thus re-establishing the validity of the narrative shared up until now.

Background: Diagnostic caveats have often been incorporated in publications suggesting possible multiple myeloma in archeological sites, noting difficulty distinguishing it from metastatic cancer. It seems appropriate to assess whether suggested cases in the archeological record differ from what modern medicine recognizes/diagnoses. Methods: The published literature and archives were surveyed for reports of multiple myeloma in archeological sites. Descriptions were examined for fulfilment of diagnostic anatomic criteria (sharply defined, spherical defects, expansion without regard for the density of surrounding bone in the absence of bone reaction or residual internal structures and contained structures). Lytic areas were examined for shape homogeneity, sharp or graded edges, relative expansion through adjacent trabecular and cortical bone and for presence of new bone formation either bordering the lesion or as periosteal reaction. Results: None of the 49 reported accessible cases described/illustrated individuals had appearances consistent with what today is recognized as multiple myeloma. The mean age of reported cases of 44 was significantly less than that of 69 in clinically diagnosed cases (t test 4.62123, p = 0.00028). Descriptions of bone lesions in many actually were often at variance with that recognized on review of their images. The significance of subtle peri-lesional density variation was often overlooked and oval lesions were often mischaracterized as "punched out." Most cases likely represent metastatic cancer. A previously unreported alteration, rosette formation, was noted in a female subgroup. Discussion: Macroscopic, radiologic and epidemiologic comparison of clinically-diagnosed cases with purported archeologic cases evidences that they represent very different diseases. Since multiple myeloma has yet to be confidently diagnosed/recognized in the archeologic record, the possibility must considered is that it is a disease of the modern epoch. A further observation is that the newly recognized finding of peri-lesional rosettes might be a marker for the breast cancer origination of observed metastases.

The main aim of the study was to identify which components of the skeleton are best identifiable after cremation, because only few publications pay attention to the best-preserved bone structures in cremation burials. However, such knowledge offers potential for further analysis and methodology development. One of the most frequently and best-identifiable parts of the skeleton were fragments of vertebrae and long bones epiphyses. Similarly, well preserved are structures made of compact bone tissue, for instance, temporal bone pyramids considered as the hardest components of the mammalian skeleton. Analysed cremated human bones remains came from a Lusatian culture settlement burial site situated in Paszowice (Lower Silesia, Poland). The research has been carried out on material consisting of remains of at least 673 individuals found in 649 burial pits. Among them, 279 burials belonged to adults and 102 to children. It was possible to identify sex in the case of 25% of adult individuals - 40 males and 33 females. In the remaining cases, the attempts to determine the sex and age-at-death have failed. During the analysis some degenerative changes were noted. The analysed material also included 23 multiple burials, usually double and one triple. The study was also aimed at illustrating the elements of the funeral rite. The material excavated from 27 burials suggested that the remains had been retrieved from the pyre with particular care - in some of those urns, the arrangement of remains was modelled on the anatomical system of the human skeleton. The grade of combustion of most bones remains in the necropolis in Paszowice ranged from high to very high. In few cases in the grave were found burned animal remains.

The purpose of this study was to assess the changes in the foot dimensions in children and adolescents (3-18 years of age) from Krakow (Poland), between the years 2010 and 2020. The examined group of children and adolescents (3-18-year olds) took part in two cross-sectional surveys carried out in 2010 and 2020. The cohort examined in 2010 consisted of 1,989 females and 1,893 males and the 2020 series included 1,702 females and 1,584 males. Body height (B-v), length of the lower limbs (B-sy) foot length (pte-ap) and breadth (mtt-mtf) were measured. The last two measurements were the basis for calculating the foot index and estimated area of the foot. Generally, children examined in 2020 had relatively wider feet in proportion to their length compared to their peers from the 2010 cohort. This change was mirrored by secular trends regarding the estimated area of the foot. Additionally, a secular decrease of the length of the foot was compensated by the increasing width of this segment of the body, which among girls occurred especially after 10 years of age. The present study provides new information regarding secular changes in foot proportions among Polish children and adolescents. Results obtained in this stud are additionally significant, as there is no similar research concerning the population of Poland.

This study examined the emergence and characteristics of bilateral asymmetry of the upper limb during development in a medieval agricultural population from Hungary, and investigated the agricultural activity-types in a bioarchaeological and biomechanical context. The skeletal remains of 169 nonadult individuals were selected from the cemetery of Bátmonostor-Pusztafalu, providing 134 cases for humeral diameter and length, 70 cases for radial length and 62 cases for ulnar length measurements. Biological age was estimated by using tooth eruption. Age groups were defined on the basis of the development of motor skills in children. Statistical analyses included correlation, Chi-square test, Fisher analysis and ANOVA. Our investigation revealed that the frequency of asymmetry increased significantly during growth with a shift to the right side in all measurements and reached adult-like distribution in early childhood. The bilateral asymmetry increased with age in humeral length, while other measurements revealed no change. The magnitude of asymmetry decreased with age in humeral diameter, but remained constant in other measurements. Our observations strengthen the hypothesis that right-sided asymmetry develops gradually during growth. Our findings also illustrate the effects of medieval agricultural labour on upper limb asymmetry: mechanical loading has various effects during development both on the magnitude and on direction of asymmetry.

The existence of a third root in the mandibular first molars may have implications for certain dental treatments; however, its greatest relevance could be in anthropological and forensic sciences, because its prevalence varies significantly according to ethnic groups. The purpose of this research was to determine the prevalence of radix entomolaris (RE) in a sample of Chilean people. A random sample of 1330 digital periapical radiographs of endodontically treated mandibular first molars (551 males and 779 females, aged between 18 and 87 years) were evaluated. The prevalence of RE, its distribution by sex and root canal lengths were determined. Evidence demonstrated that the formation of RE is associated with ancestry and its frequency is variable according to populations studied, being more frequent in Asians and Native Americans. The prevalence of RE in the studied people was 3.16%, similar to frequencies reported in European individuals (3.4%-4.2%). The 61.90% of RE were located at the right side of the mandible and 38.10% at the left side. The average working length of RE was 19.52 mm. No statistically significant differences in frequencies were observed by sex (p = 0.19). The prevalence of RE varies among continental population groups. However, due to human migration, the frequency of this physical trait could be modified in specific geographic regions. The observed prevalence of RE in the study group was similar to the prevalence ranges observed for European ancestry populations and it was considerably lower than the data reported for non-Europeans. The absence of sexual dimorphism is consistent with results of previous studies performed worldwide.
