The genetic origin of the Indo-Europeans.

The Yamnaya archaeological complex appeared around 3300 BC across the steppes north of the Black and Caspian Seas, and by 3000 BC it reached its maximal extent, ranging from Hungary in the west to Kazakhstan in the east. To localize Yamnaya origins among the preceding Eneolithic people, we assembled ancient DNA from 435 individuals, demonstrating three genetic clines. A Caucasus-lower Volga (CLV) cline suffused with Caucasus hunter-gatherer ancestry extended between a Caucasus Neolithic southern end and a northern end at Berezhnovka along the lower Volga river.

A glimpse into the past of Hansen's disease - Re-evaluation and comparative analysis of cases with leprosy from the Avar period of the Trans-Tisza region, Hungary.

Our knowledge of how society viewed leprosy and treated its victims in the past is still scarce, especially in geographical regions and archaeological periods from where no written sources are available. To fill in some research gaps, we provide the comparative analysis of five previously described, probable cases with leprosy from the Avar-period Trans-Tisza region (Hungary). The five skeletons were subject to a detailed macromorphological (re-)evaluation.

The Genetic Origin of the Indo-Europeans.

The Yamnaya archaeological complex appeared around 3300BCE across the steppes north of the Black and Caspian Seas, and by 3000BCE reached its maximal extent from Hungary in the west to Kazakhstan in the east. To localize the ancestral and geographical origins of the Yamnaya among the diverse Eneolithic people that preceded them, we studied ancient DNA data from 428 individuals of which 299 are reported for the first time, demonstrating three previously unknown Eneolithic genetic clines. First, a "Caucasus-Lower Volga" (CLV) Cline suffused with Caucasus hunter-gatherer (CHG) ancestry extended between a Caucasus Neolithic southern end in Neolithic Armenia, and a steppe northern end in Berezhnovka in the Lower Volga.

Re-examination of the Subalyuk Neanderthal remains uncovers signs of probable TB infection (Subalyuk Cave, Hungary).

In 1932, skeletal remains of two Neanderthal individuals, a young adult female and a 3-4-year-old child, were discovered in Subalyuk Cave in Northern Hungary [1,2]. Results of the anthropological examination were published some years after this important discovery. Methodological progress encouraged re-examination of the material during the last few years.

More than one millennium (2nd-16th century CE) of the White Plague in the Carpathian Basin - New cases, expanding knowledge.

The causative agent of tuberculosis is still a widespread pathogen, which caused the death of ca. 1.6 million people globally in 2021.

Leprosy: The age-old companion of humans - Re-evaluation and comparative analysis of Avar-period cases with Hansen's disease from the Danube-Tisza Interfluve, Hungary.

In recent years, our knowledge of leprosy in the past has substantially been enriched. Nonetheless, much still remains to be discovered, especially in regions and periods from where no written sources are available. To fill in some research gaps, we provide the comparative analysis of eight Avar-period leprosy cases from the Danube-Tisza Interfluve (Hungary).

Lumbosacral tuberculosis, a rare manifestation of Pott's disease - How identified human skeletons from the pre-antibiotic era can be used as reference cases to establish a palaeopathological diagnosis of tuberculosis.

The macromorphological examination of identified human osteological collections from the pre-antibiotic era (e.g., Terry Collection) can provide invaluable information about the skeletal manifestations of tuberculosis (TB) in individuals who did not receive pharmaceutical therapy.

Development of bilateral asymmetry of the upper limb in children from a medieval population in Central Europe, Hungary.

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.

A rare case of calvarial tuberculosis from the Avar Age (8th century CE) cemetery of Kaba-Bitózug (Hajdú-Bihar county, Hungary) - Pathogenesis and differential diagnostic aspects.

The aim of our paper is to present and discuss in detail the bony changes indicative of tuberculosis (TB) that were identified in a skeleton (KB67), unearthed from grave 67 of the 8th-century-CE cemetery of Kaba-Bitózug (Hungary). Furthermore, to provide the differential diagnoses of the observed alterations, with special attention to the cranial osteolytic lesions. During the macro- and micromorphological examinations of KB67, the skull revealed three small, well-circumscribed, punched-out osteolytic lesions accompanied by endocranial granular impressions, abnormal blood vessel impressions, periosteal appositions, and cortical erosion.

The two extremes of Hansen's disease-Different manifestations of leprosy and their biological consequences in an Avar Age (late 7th century CE) osteoarchaeological series of the Duna-Tisza Interfluve (Kiskundorozsma-Daruhalom-dűlő II, Hungary).

To give an insight into the different manifestations of leprosy and their biological consequences in the Avar Age of the Hungarian Duna-Tisza Interfluve, two cases from the 7th-century-CE osteoarchaeological series of Kiskundorozsma-Daruhalom-dűlő II (Hungary; n = 94) were investigated. Based on the macromorphology of the bony changes indicative of Hansen's disease, KD271 (a middle-aged male) and KD520 (a middle-aged female) represent the two extremes of leprosy. KD271 appears to have an advanced-stage, long-standing near-lepromatous or lepromatous form of the disease, affecting not only the rhinomaxillary region but also both upper and lower limbs.

Correction: Life and death of a leprosy sufferer from the 8th-century-CE cemetery of Kiskundorozsma-Kettőshatár I (Duna-Tisza Interfluve, Hungary)-Biological and social consequences of having Hansen's disease in a late Avar Age population from Hungary.

Life and death of a leprosy sufferer from the 8th-century-CE cemetery of Kiskundorozsma-Kettőshatár I (Duna-Tisza Interfluve, Hungary)-Biological and social consequences of having Hansen's disease in a late Avar Age population from Hungary.

The aim of our paper is to demonstrate a middle-aged male (KK61) from the 8th-century-CE cemetery of Kiskundorozsma-Kettőshatár I (Duna-Tisza Interfluve, Hungary), who appears to represent the lepromatous form of Hansen's disease. Leprosy has affected not only the rhinomaxillary region of his face but also his lower limbs, with severe deformation and disfigurement of the involved anatomical areas (saddle-nose and flat-foot deformity, respectively). Consequently, he would have experienced disability in performing the basic activities of daily living, such as eating, drinking, standing or walking; and thus, he would have required regular and substantial care from others to survive.

An unusual case of childhood osteoarticular tuberculosis from the Árpádian Age cemetery of Győrszentiván-Révhegyi tag (Győr-Moson-Sopron county, Hungary).

Ancient human remains exhibiting bony changes consistent with osteoarticular tuberculosis (OATB) indicate that the disease has afflicted mankind for millennia. Nonetheless, not many pediatric OATB cases have been published in the paleopathological literature-from Hungary, only three cases have been described up to now. In our paper, we demonstrate a child (S0603) from the Árpádian Age cemetery of Győrszentiván-Révhegyi tag (northwestern Hungary), who represents a unique case of OATB regarding both the pattern and severity of the observed bony changes.

Tracking down the White Plague. Chapter three: Revision of endocranial abnormally pronounced digital impressions as paleopathological diagnostic criteria for tuberculous meningitis.

Abnormally pronounced digital impressions (APDIs) on the endocranial surface develop secondary to a prolonged rise in the intracranial pressure. This can result from a number of pathological conditions, including hydrocephalus due to tuberculous meningitis (TBM). APDIs have been described with relation to TBM not only in the modern medical literature but also in several paleopathological studies.

Tracking down the White Plague. Chapter two: The role of endocranial abnormal blood vessel impressions and periosteal appositions in the paleopathological diagnosis of tuberculous meningitis.

Although endocranial abnormal blood vessel impressions (ABVIs) and periosteal appositions (PAs) have been considered as paleopathological diagnostic criteria for tuberculous meningitis (TBM) based on findings of previous studies, they are not pathognomonic for tuberculosis (TB). Therefore, their utilization in the paleopathological practice can be questioned, especially in consideration that most of the previous studies were not performed on identified skeletal collections but on osteoarchaeological material and did not include statistical data analysis. To fill the aforementioned research gap, for the first time, a macroscopic investigation was conducted on identified pre-antibiotic era skeletons from the Terry Collection.

Author Correction: Genetic insights into the social organisation of the Avar period elite in the 7th century AD Carpathian Basin.

Tracking down the White Plague: The skeletal evidence of tuberculous meningitis in the Robert J. Terry Anatomical Skeletal Collection.

Paleopathological diagnosis of tuberculosis (TB) essentially relies on the identification of macroscopic lesions in the skeleton that can be related to different manifestations of TB. Among these alterations, granular impressions (GIs) on the inner skull surface have been considered as pathognomonic features of tuberculous meningitis (TBM). GIs may be established by pressure atrophy of the tubercles formed on the outermost meningeal layer during later stages of TBM.

Y-chromosome haplogroups from Hun, Avar and conquering Hungarian period nomadic people of the Carpathian Basin.

Hun, Avar and conquering Hungarian nomadic groups arrived to the Carpathian Basin from the Eurasian Steppes and significantly influenced its political and ethnical landscape, however their origin remains largely unknown. In order to shed light on the genetic affinity of above groups we have determined Y chromosomal haplogroups and autosomal loci, suitable to predict biogeographic ancestry, from 49 individuals, supposed to represent the power/military elit. Haplogroups from the Hun-age are consistent with Xiongnu ancestry of European Huns.

Osteoarcheological and biomolecular evidence of leprosy from an 11-13 century CE Muslim cemetery in Europe (Orosháza, Southeast Hungary).

Orosháza site no. 10 (Southeast Hungary) contains the partially excavated archaeological remains of an 11-13 century CE Muslim merchant village and its cemetery located in close proximity to Christian villages of the same era. The skeleton of a young woman (grave no.

Hyperostosis frontalis interna in ancient populations from the Carpathian Basin - A possible relationship between lifestyle and risk of development.

Objective: The prevalence of hyperostosis frontalis interna (HFI) was examined in different periods of the Carpathian Basin from 4900 BCE to 17th century AD. The study seeks to evaluate temporal changes in HFI and the possible impact of lifestyle on it.

Materials: The studied material consisted of 4668 crania from Hungary and Serbia.

Ancient genomes reveal a high diversity of Mycobacterium leprae in medieval Europe.

Studying ancient DNA allows us to retrace the evolutionary history of human pathogens, such as Mycobacterium leprae, the main causative agent of leprosy. Leprosy is one of the oldest recorded and most stigmatizing diseases in human history. The disease was prevalent in Europe until the 16th century and is still endemic in many countries with over 200,000 new cases reported annually.

Parallel palaeogenomic transects reveal complex genetic history of early European farmers.

Ancient DNA studies have established that Neolithic European populations were descended from Anatolian migrants who received a limited amount of admixture from resident hunter-gatherers. Many open questions remain, however, about the spatial and temporal dynamics of population interactions and admixture during the Neolithic period. Here we investigate the population dynamics of Neolithization across Europe using a high-resolution genome-wide ancient DNA dataset with a total of 180 samples, of which 130 are newly reported here, from the Neolithic and Chalcolithic periods of Hungary (6000-2900 bc, n = 100), Germany (5500-3000 bc, n = 42) and Spain (5500-2200 bc, n = 38).
