Furthermore, the results obtained with the location of microsatellites corroborate with the temperature sex determination mechanism proposal and the absence of heteromorphic sex chromosomes in sea turtles. The findings are useful for understanding part of the karyotypic diversification observed in sea turtles, especially those that explain the diversification of Carettini from Chelonini species.Early age acute leukemia (EAL) shows a high frequency of KMT2A-rearrangements (KMT2A-r). Previous investigations highlighted double-strand breaks arising from maternal exposure to xenobiotics during pregnancy as a risk factor for EAL and KMT2A-r. In this case-control study, we investigated the relationship between EAL and genetic variants of the nonhomologous end-joining (XRCC6 rs5751129, XRCC4 rs6869366 and rs28360071), since they might affect DNA repair capacity, leading to KMT2A-r and leukemogenesis. Samples from 577 individuals (acute lymphoblastic leukemia-ALL, n=164; acute myeloid leukemia-AML, n=113; controls, n=300) were genotyped. No significant association was found for rs5751129 and rs6869366, whereas rs28360071 was associated with an increased risk for ALL with KMT2A-r (IIxID OR - Odds ratio 2.23, CI 1.17-4.25, p=0.014). Bone marrow samples from ALL patients showed a higher expression of XRCC4 compared to AML patients (p=0.025). Human Splicing Finder 3.1 predicted that the deleted allele of rs28360071 is potentially associated with the activation of a 5' cryptic splice site in intron 3 of XRCC4. The sequencing of cDNA did not show any differences on the splicing process for the rs28360071 genotypes. Siponimod manufacturer Our results suggest that the deleted allele for rs28360071 increases the risk for ALL with KMT2A-r, but not by modifying the XRCC4 expression levels or its structure.This paper presents results of palaeopathological investigations carried out on a total of 133 cremation burials from the Bronze Age, Iron Age and Roman Imperial Period from Germany, the Czech and the Slovak Republics and Turkey. With the fragments of the 118 skulls in total, the aim was to document, diagnose and examine pathological conditions as completely and extensively as possible. These were investigated macromorphologically and then further examined radiologically, scanning electron microscopically and light microscopically in order to create a methodological basis for the determination of the effects of cremation on pathological vestiges on the bones and the extent to which the intra vitam processes involved in the cremation remain detectable. The investigation provided a number of different diagnoses of different types of pathological processes in all areas of the skull. Thus, with the support of light microscopy, haemorrhagic or inflammatory changes on the internal or external lamina of the skull vault were detected, traces of inflammation in the paranasal sinuses, as well as, a whole spectrum of dental pathologies. In approximately every tenth skull from the investigated cremation burials, at least one or several pathological conditions was observed. It should be noted that these results cannot be compared with the frequencies and diagnostic possibilities in inhumations and such use would be methodologically unjustifiable. Nevertheless, supported by modern methods, it is a significant extension of the range of anthropological research on cremated human remains and the methodology in their examination.Carbonised and calcined animal bones are regularly present in archaeological contexts. If they appear in combination with human burial sites, especially cremations, their function as food offerings is a safe guess. The occurrence of burnt animal bones in only small quantities rarely causes debate, as faunal remains usually come into contact with heat during food preparation - for example cooking over an open fire or in an oven, resulting in partial carbonisation - which can extend to the complete destruction of the organic components (calcination). However, if burned and calcined bones are present in unusually high proportions, they often provoke the impression that they are the relics of religious acts, e.g. ritual feasts or burning sacrifices. This study uses the faunal remains from two Bronze to Iron Age sites in the Jülicher Börde (North Rhine-Westphalia, Germany) to demonstrate that not only the location and situation of the deposit, but also, in particular, the distribution of burning traces on the various skeletal elements found in the different animal species, can provide important information about profane or religiously motivated deposition.

To evaluate the 5-year results of the clinical and radiographic outcomes of three types of early loaded implants.

Seventy-five implants were placed in the posterior mandible or maxilla in 30 patients. Three types of implants (Straumann SLActive, Astra OsseoSpeed, and Thommen Implant System) were used. Definitive restorations were made after 8 weeks of implant placement. The radiographs were taken at the placement of the prosthesis, at 6 months, and at 1- and 5-year follow-ups. Clinical and radiologic data were evaluated for all types of implants. The Wilcoxon signed rank test, least significant differences, and Mann-Whitney U were used to test for statistically significant differences (P < .005).

Twenty-four patients and 62 implants were evaluated after 5 years. The mean marginal bone loss was 0.20 ± 0.40 mm, 0.21 ± 0.05 mm, and 0.25 ± 0.36 mm after 1 year and 0.32 ± 0.22 mm, 0.31 ± 0.26 mm, and 0.42 ± 0.36 mm after 5 years for the Straumann, Astra, and Thommen groups, respectively. After 5 years, the mean peri-implant probing depth level was 1.75 ± 0.49 mm, 1.87 ± 0.48 mm, and 1.92 ± 0.57 mm for the Straumann, Astra, and Thommen groups, respectively. No peri-implantitis was detected after 5 years of loading.

All groups of implants showed a stable peri-implant probing depth and marginal bone level. The survival rate was high and bone loss was low at 5 years; thus, early loading may be a useful procedure that allows reduction in treatment time.
