The etiology of this disease has remained highly controversial, ranging from claims based on genetics and the historical descriptions of symptoms that it was caused by Yersinia pestis to concl...
Ancient DNA (aDNA) analysis of extinct ratite species is of considerable interest as it provides important insights into their origin, evolution, paleogeographical distribution and vicariant speciation in congruence with continental drift theory. In this study, DNA hotspots were detected in fossilized eggshell fragments of ratites (dated ≥25000 years B.P. by radiocarbon dating) using confocal l...
D-RNAi (Messenger RNA-antisense DNA interference), a novel posttranscriptional phenomenon of silencing gene expression by transfection of mRNA-aDNA hybrids, was originally observed in the effects of bcl-2 on phorbol ester-induced apoptosis in human prostate cancer LNCaP cells. This phenomenon was also demonstrated in chicken embryos and a human CD4(+) T cell line, H9. The in vivo transduction o...
The evolutionary history of modern humans is characterized by numerous migrations driven by environmental change, population pressures, and cultural innovations. In Europe, the events most widely considered to have had a major impact on patterns of genetic diversity are the initial colonization of the continent by anatomically modern humans (AMH), the last glacial maximum, and the Neolithic tra...

In this vein, aim article was to analyze issue children's rights, discussion which still under debate not fully satisfy all parties involved. The authors used set methods including: logical, ch...
Podlaskie cmentarzyska z grobami w obstawach kamiennych w świetle wyników badań interdyscyplinarnych
W artykule prezentowane są wybrane wyniki badań projektu pt. „Początki chrześcijaństwa na pograniczu mazowiecko-ruskim”, realizowanego w latach 2013–2016 Instytucie Archeologii i Etnologii PAN pod kierownictwem prof. dr. hab. Andrzeja Buko. Przedmiotem tych były wczesnośredniowieczne cmentarzyska szkieletowe Podlasiu. Analizy aDNA wykazały, że ludność pochowana kurhanach genetycznie różniła się...
