[Case report: molecular analysis of congenital glioblastoma in a newborn].

Congenital glioblastoma (cGBM) is a brain tumor very rarely observed in newborns and young infants, and differs in several respects from glioblastoma (GBM) of childhood and adulthood. Our aim was the presentation of a cGBM case with 14 days of postnatal survival at the Pediatric Oncology Center of the Markusovszky University Teaching Hospital in 2004. We investigated formalin-fixed, paraffin-embedded autoptic tumor samples of the newborn by immunohistochemical and molecular genetic (FISH and pyrosequencing) methods.

Wnt pathway markers in low-grade and high-grade gliomas.

Background And Purpose: Aberrant activation of the Wnt pathway contributes to differentiation and maintenance of cancer stem cells underlying gliomagenesis. The aim of our research was to determine as to what degrees some Wnt markers are expressed in gliomas of different grades, lineages and molecular subtypes.

Methods: Nine grade II, 10 grade III and 72 grade IV surgically removed, formalin-fixed paraffin-embedded glioma specimens were included.

Detection of Dobrava-Belgrade hantavirus using recombinant-nucleocapsid-based enzyme-linked immunosorbent assay and SYBR Green-based real-time reverse transcriptase-polymerase chain reaction.

Dobrava (DOBV) hantaviruses belong to the genus Hantavirus, family Bunyaviridae, and are carried by yellow-necked and striped field mice. The goal of this study was to detect DOBV using serological and genetic methods in Apodemus rodents in Hungary and in northern Croatia. During the study period, a total of 125 Apodemus sp.
