TL;DR: Several well known tumor biomarkers are detected in the pathological skeletal remain of a 2000-year-old ancient bone remain with osteogenic sarcoma, which can be useful in the discovery of malignant bone lesions such as osteosarcoma in the very early stage of the disease from paleoanthropological remains.
Abstract: Osteosarcoma is the most common primary malignant tumor of bone usually occurring in young adolescent and children. This disease has a poor prognosis, because of the metastases in the period of tumor progression, which are usually developed previous to the clinical diagnosis. In this paper, a 2000-year-old ancient bone remain with osteogenic sarcoma was analyzed searching for tumor biomarkers which are closely related to this disease. After a specific extraction SDS-PAGE gel electrophoresis followed by tryptic digestion was performed. After the digestion the samples were measured using MALDI TOF/TOF MS. Healthy bone samples from same archaeological site were used as control samples. Our results show that in the pathological skeletal remain several well known tumor biomarkers are detected such as annexin A10, BCL-2-like protein, calgizzarin, rho GTPase-activating protein 7, HSP beta-6 protein, transferrin and vimentin compared to the control samples. The identified protein biomarkers can be useful in the discovery of malignant bone lesions such as osteosarcoma in the very early stage of the disease from paleoanthropological remains.

TL;DR: Men and women had a similar roles in the Early Neolithic migration process but their dispersal patterns were determined by sex-specific rules, and further support the migration from the Near East into Central Europe along the Continental route of Neolithisation.
Abstract: Farming was established in Central Europe by the Linearbandkeramik culture (LBK), a well-investigated archaeological horizon, which emerged in the Carpathian Basin, in today's Hungary. However, the genetic background of the LBK genesis has not been revealed yet. Here we present 9 Y chromosomal and 84 mitochondrial DNA profiles from Mesolithic, Neolithic Starcevo and LBK sites (7th/6th millennium BC) from the Carpathian Basin and south-eastern Europe. We detect genetic continuity of both maternal and paternal elements during the initial spread of agriculture, and confirm the substantial genetic impact of early farming south-eastern European and Carpathian Basin cultures on Central European populations of the 6th-4th millennium BC. Our comprehensive Y chromosomal and mitochondrial DNA population genetic analyses demonstrate a clear affinity of the early farmers to the modern Near East and Caucasus, tracing the expansion from that region through south-eastern Europe and the Carpathian Basin into Central Europe. Our results also reveal contrasting patterns for male and female genetic diversity in the European Neolithic, suggesting patrilineal descent system and patrilocal residential rules among the early farmers.

TL;DR: The Ankarana Tsingy as mentioned in this paper is built up of giant grikes, which developed along cracks and such smaller different karren forms, which are on surfaces between the grikes.
Abstract: The Ankarana Tsingy is presented from Madagascar. Various investigations were carried out on the tsingy. The tsingy has two occurrences: the Ankarana Tsingy and the Bemaraha Tsingy. The Ankarana Tsingy is built up of giant grikes, which developed along cracks and such smaller different karren forms, which are on surfaces between the grikes. Assemblages of tsingy can be distinguished by analysing the patterns and the sizes of the grikes. According to its morphology the tsingy can be blade tsingy, clint tsingy and tower tsingy. The grikes developed during non-soil dissolution. Rainfall percolating into the cracks created grikes where as the karren forms of the clints were created by rainfall falling on the surface of the clints. By using our measurements and data we describe the development of the tsingy. The young tsingy can be clint tsingy and blade tsingy. Clint tsingy develops if the grikes are created along cracks which are perpendicular to each other and those are far from each other. Blade tsingy develops if grikes are created along creaks which have a single direction and their density is great. Old tsingy develops from the clint tsingy when grikes widen. It can also develop from the blade tsingy if grikes are created along a new direction. And these grikes dissect the ridges of the blade tsingy. Towers (tower tsingy) develop during the process. Destroying and destroyed tsingy develop if the towers fall due to their destroying process.

TL;DR: The somatotypes of manic-depressive females investigated show a balanced mesomorphic-endomorphic predominance, according to the recent study, Kretschmer's statements (1921) are still valid in manic-Depressive females.
Abstract: The purpose of this study was to get new data about the physique (somatotype) of manic-depressive patients. The somatotypes of manic-depressive females (n = 31, mean age: 30 year) investigated show a balanced mesomorphic-endomorphic predominance. The mean somatotype was 6.34, 5.27, 1.39. Previous Hungarian studies showed a meso-endomorphic somatotype in manic-depressive females. The physique of these patients determined by Kretschmer as pycnic did not show significant alteration due to environmental changes. Thus, according to the recent study, Kretschmer's statements (1921) are still valid in manic-depressive females. They are invariably characterized by a pycnic physique.

TL;DR: In this paper, the authors generated genome-wide data from 69 Europeans who lived between 8,000-3,000 years ago by enriching ancient DNA libraries for a target set of almost 400,000 polymorphisms.
Abstract: We generated genome-wide data from 69 Europeans who lived between 8,000-3,000 years ago by enriching ancient DNA libraries for a target set of almost 400,000 polymorphisms. Enrichment of these positions decreases the sequencing required for genome-wide ancient DNA analysis by a median of around 250-fold, allowing us to study an order of magnitude more individuals than previous studies and to obtain new insights about the past. We show that the populations of Western and Far Eastern Europe followed opposite trajectories between 8,000-5,000 years ago. At the beginning of the Neolithic period in Europe, ∼8,000-7,000 years ago, closely related groups of early farmers appeared in Germany, Hungary and Spain, different from indigenous hunter-gatherers, whereas Russia was inhabited by a distinctive population of hunter-gatherers with high affinity to a ∼24,000-year-old Siberian. By ∼6,000-5,000 years ago, farmers throughout much of Europe had more hunter-gatherer ancestry than their predecessors, but in Russia, the Yamnaya steppe herders of this time were descended not only from the preceding eastern European hunter-gatherers, but also from a population of Near Eastern ancestry. Western and Eastern Europe came into contact ∼4,500 years ago, as the Late Neolithic Corded Ware people from Germany traced ∼75% of their ancestry to the Yamnaya, documenting a massive migration into the heartland of Europe from its eastern periphery. This steppe ancestry persisted in all sampled central Europeans until at least ∼3,000 years ago, and is ubiquitous in present-day Europeans. These results provide support for a steppe origin of at least some of the Indo-European languages of Europe.

TL;DR: A genome-wide scan for selection using ancient DNA is reported, capitalizing on the largest ancient DNA data set yet assembled: 230 West Eurasians who lived between 6500 and 300 bc, including 163 with newly reported data.
Abstract: Ancient DNA makes it possible to observe natural selection directly by analysing samples from populations before, during and after adaptation events. Here we report a genome-wide scan for selection using ancient DNA, capitalizing on the largest ancient DNA data set yet assembled: 230 West Eurasians who lived between 6500 and 300 bc, including 163 with newly reported data. The new samples include, to our knowledge, the first genome-wide ancient DNA from Anatolian Neolithic farmers, whose genetic material we obtained by extracting from petrous bones, and who we show were members of the population that was the source of Europe's first farmers. We also report a transect of the steppe region in Samara between 5600 and 300 bc, which allows us to identify admixture into the steppe from at least two external sources. We detect selection at loci associated with diet, pigmentation and immunity, and two independent episodes of selection on height.

TL;DR: Genome-wide data from 400 Neolithic, Copper Age and Bronze Age Europeans is presented, finding limited genetic affinity between Beaker-complex-associated individuals from Iberia and central Europe, and excludes migration as an important mechanism of spread between these two regions.
Abstract: From around 2750 to 2500 bc, Bell Beaker pottery became widespread across western and central Europe, before it disappeared between 2200 and 1800 bc. The forces that propelled its expansion are a matter of long-standing debate, and there is support for both cultural diffusion and migration having a role in this process. Here we present genome-wide data from 400 Neolithic, Copper Age and Bronze Age Europeans, including 226 individuals associated with Beaker-complex artefacts. We detected limited genetic affinity between Beaker-complex-associated individuals from Iberia and central Europe, and thus exclude migration as an important mechanism of spread between these two regions. However, migration had a key role in the further dissemination of the Beaker complex. We document this phenomenon most clearly in Britain, where the spread of the Beaker complex introduced high levels of steppe-related ancestry and was associated with the replacement of approximately 90% of Britain's gene pool within a few hundred years, continuing the east-to-west expansion that had brought steppe-related ancestry into central and northern Europe over the previous centuries.
