Abstract

The loess/paleosol sequence near the village of Madaras is an outstanding record of Late Quaternary paleoenvironmental and paleoclimatic changes in Hungary and the entire Carpathian Basin. The present study highlights the results of preliminary micromorphological investigations implemented on 24 samples taken from two pre-selected pedogenized horizons of the sequence. Our work yielded interesting results regarding the evolutionary history and modes of pedogenesis in the studied section.

A paragangliomák a szimpatikus vagy paraszimpatikus ganglionokból kiinduló, többségükben jóindulatú daganatok, de rosszindulatú formájuk is ismert. A fej-nyak régióban, a glomus caroticumban, illetve a vegetatív idegrendszer dúcláncának megfelelően a hasüregben, illetve a mellüregben is előfordulhatnak. A 39 éves férfi beteg kivizsgálása extrém magas vérnyomásértékek, éjszakai izzadás és 10 kg-os fogyás miatt kezdődött. A mellkas-CT-vizsgálat a jobb oldali tüdőkapuban óriási térfoglalást írt le, a bronchoszkópos mintavétel sikertelen volt. Jobb oldali thoracotomiából mintavétel történt, reszekcióra a kifejezett adhéziók, illetve a szívérintettség miatt nem volt lehetőség. A szövettani vizsgálat eredménye paraganglioma lett, ezt a laborvizsgálatok is támogatták. Ennek megfelelőn szomatosztatinanalóg-terápiát kezdtünk, majd ¹³¹I-MIBG-kezelést alkalmaztunk, jó klinikai eredménnyel. A koronarográfia során észleltük, hogy a jobb coronaria két marginális ággal hozzájárul a mellkasi terime vérellátásához. Megfelelő előkészítést követően, szív- és mellkassebészeti beavatkozással a tumor eltávolíthatónak bizonyult, ennek eredményeként a posztoperatív szakban a beteg vérnyomáscsökkentőit elhagytuk. A kontrollok során tumormaradványra utaló jel nem volt. A vérnyomáskiugrások okának keresésekor merüljön fel bennünk a paraganglioma lehetősége is. Ezen esetekben az invazív beavatkozások, amennyiben nem előzi meg őket gyógyszeres előkészítés, akár fatális kimenetellel járhatnak. Az egyre szélesedő terápiás lehetőségek kihasználásával és az intézetek közötti kooperációval az óriás-paragangliomában szenvedő betegek is tumormentessé tehetők.

Abstract

We present the results of the environmental historical and geoarchaeological analysis of Rákóczifalva-Bagi- földek and Rákóczifalva-Rokkant-földek archeological sites in Jász-Nagykun-Szolnok County. They were discovered in the course of several hectares of archaeological excavations related to the Roman Age and Migration Period, especially the Sarmatian and the Gepids era. A significant number of Gepids sites and finds were found in both the investigated areas and the wider area of the site, in the middle reach of the Tisza valley. So the geoarchaeological and environmental historical analysis of the Sarmatian and Late-Sarmatian and Gepids sites in Rákóczifalva can also provide a model for the settling strategy and lifestyle of the Sarmatian and Gepids communities. The purpose of our work is to present how geoarchaeological and environmental historical factors impacted local settling and lifestyles in the Gepids communities and Sarmatian-Late Sarmatian communities as well during the Roman Age and the Migration Period. In addition, to demonstrate the relationship of the Sarmatian and Gepids communities and their environment in the Rákóczifalva site compared to other Gepids and Sarmatian and Late Sarmatian communities in the Great Hungarian Plain.

Based on the number of objects containing animal bones and the amount of bones found in them, we can reconstruct considerable settling in the Celtic, Sarmatian, Gepids, Avar and Arpadian periods. The number of objects from the Linear Pottery culture (Great Hungarian Plain) and the Bodrogkeresztúr culture is high; however, the number of animal bones is low. On the basis of the bones discovered, we can count on a smaller settlement during the Tiszapolgár culture, the Hunyadihalom group, the Halomíros culture, the Gava culture and during the Scythians period.

In this paper, we present the results of the Sarmatian, Late Sarmatian and the Gepid findings since the largest number of animal bones (except the Avar period) turned up from these periods. Our aim was to compare the animal husbandry, meat consumption and hunting habits of the Oriental origin Sarmatians and the Germanic Gepids communities. Bone artefacts and bone anvils have been found in the archaeological material of both ethnic groups.

Abstract

The Madaras brickyard section found at the northernmost fringe of the Backa loess plateau is one of the thickest and best-developed last glacial loess sequences of Central Europe. In the present work high-resolution magnetic susceptibility measurements (at 2 cm) were implemented on samples from the 10 m-section corresponding to a period between 29 and 11 KY cal b2K. One aim was to compare the findings with the ice core records of northern Greenland in order to establish a high-resolution paleoclimatic record for the last climatic cycle and with findings documented in other biotic and abiotic proxies so far. Our results revealed a strong variability of loess/paleosol formation during MIS 2. Millennial time-scale climatic events that characterize the North Atlantic during the last climatic cycle have been identified. From 29 ka up to the start of the LGM, the recorded MS values show a weak, negative correlation with the temperature proxy, and a weak positive correlation with the dust concentration of Greenland. A strong correlation was observed with the local paleotemperatures. Local climatic factors must have had a more prominent effect here on loess/paleosol development than the climate shifts over Greenland. During the LGM the same pattern is seen with a stronger correlation with the dust concentrations and a weaker correlation with the local temperature. Local climatic factors, plus dust accumulation, must have had a prominent influence on loess/paleosol development here. From the terminal part of the LGM a strong positive correlation of the MS values with the temperature proxy for Greenland accompanied by a strong negative correlation with the dust concentration values is observed. Correlation with local paleotemperatures is positive and moderate, strong. Here climate shifts over Greenland, as well as local endowments equally had an important role on the development of the MS signal.
