Tuberculosis in prehistory in Eastern Central Europe (Hungary) - Chronological and geographical distribution.

Tuberculosis (TB) has long been a major scourge of humankind. Paleopathological and paleomicrobiological studies have revealed the past presence of the disease on a large spatial and temporal scale. The antiquity of the disease has extensively been studied in the Carpathian Basin, given its dynamic population and cultural changes since prehistory. These studies, however, have mainly focused on the populations living during the Common Era. The aim of this paper is to present the published and the recently discovered cases of prehistoric TB, from the Neolithic (6000-4500/4400 BCE) to the Bronze Age (2600/2500-800 BCE) Central Carpathian Basin (Hungary). We summarize 18 published cases and present new cases dating to the Neolithic period and introduce 3 newly discovered Bronze Age cases of TB. Despite extensive research, TB has not yet been identified from the Copper and Iron Ages in the Carpathian Basin. Considering the state of TB research, and supplemented by our prehistoric dataset, the spatio-temporal pattern of the disease can be further elucidated, thus advancing future molecular and paleopathological studies. Our dataset offers comprehensive spatial and temporal information on the spread of the disease in the Carpathian Basin, along with a detailed biological profile of the demonstrated cases and extensive paleopathological descriptions of the observed lesions, complemented by photographic evidence. This invaluable resource paves the way for enhanced understanding and progress in the field.

5000 years of dietary variations of prehistoric farmers in the Great Hungarian Plain.

The development of farming was a catalyst for the evolution of the human diet from the varied subsistence practices of hunter-gatherers to the more globalised food economy we depend upon today. Although there has been considerable research into the dietary changes associated with the initial spread of farming, less attention has been given to how dietary choices continued to develop during subsequent millennia. A paleogenomic time transect for 5 millennia of human occupation in the Great Hungarian Plain spanning from the advent of the Neolithic to the Iron Age, showed major genomic turnovers. Here we assess where these genetic turnovers are associated with corresponding dietary shifts, by examining the carbon and nitrogen stable isotope ratios of 52 individuals. Results provide evidence that early Neolithic individuals, which were genetically characterised as Mesolithic hunter-gatherers, relied on wild resources to a greater extent than those whose genomic attributes were of typical Neolithic European farmers. Other Neolithic individuals and those from the Copper Age to Bronze Age periods relied mostly on terrestrial C3 plant resources. We also report a carbon isotopic ratio typical of C4 plants, which may indicate millet consumption in the Late Bronze Age, despite suggestions of the crop's earlier arrival in Europe during the Neolithic.

One week of exposure to 50 Hz, vertical magnetic field does not reduce urinary 6-sulphatoxymelatonin excretion of male wistar rats.

The effect of exposure to 100 or 50 microT, 50 Hz, vertical magnetic field on the excretion of 6-sulphatoxymelatonin (6SM) in the nocturnal urine of rats was studied. Twelve male Wistar rats were kept under 12:12 hr light:dark conditions. The nocturnal urine of animals was collected in metabolic cages over 4 consecutive weeks. The concentration of 6SM in the rat urine was measured by 125I radioimmunoassay and normalized to creatinine concentration. After the first week of urine collection, 6 rats were exposed to 100 microT or 50 microT flux density magnetic fields (MF) for 8 hr daily for 1 week. It was found that the excretion of the primary metabolite of melatonin in the urine, 6SM, did not show statistically significant changes during and after magnetic field exposure.
