Telomerase activity distinguishes between neuroblastomas with poor prognosis

Association of telomerase activity with radio- and chemosensitivity of neuroblastomas

BACKGROUND Telomerase activity compensates shortening of telomeres during cell division and enables cancer cells to escape senescent processes. It is also supposed, that telomerase is associated with radio- and chemoresistance. In the here described study we systematically investigated the influence of telomerase activity (TA) and telomere length on the outcome of radio- and chemotherapy in neu...

CpG island methylator phenotype is a strong determinant of poor prognosis in neuroblastomas.

Neuroblastoma, one of the most common pediatric solid tumors, is characterized by two extreme disease courses, spontaneous regression and life-threatening progression. Here, we conducted a genome-wide search for differences in DNA methylation that distinguish between neuroblastomas of the two types. Three CpG islands (CGI) and two groups of CGIs were found to be methylated specifically in neuro...

Recurrent Implantation Failure Is More Frequently Seen in Female Patients with Poor Prognosis

Predictors of Poor Prognosis in Aluminum Phosphide Intoxication

ABSTRACT Background: Aluminum phosphide as a fumigant is extensively used for wheat preservation from rodents and bugs especially in silos worldwide. There is increasing number of acute intoxication with this potentially lethal compound because of its easy availability. We have tried to locate predictors of poor prognosis in patients with aluminum phosphide intoxication in order to find patien...

Electrocortical activity distinguishes between uphill and level walking in humans.

The objective of this study was to determine if electrocortical activity is different between walking on an incline compared with level surface. Subjects walked on a treadmill at 0% and 15% grades for 30 min while we recorded electroencephalography (EEG). We used independent component (IC) analysis to parse EEG signals into maximally independent sources and then computed dipole estimations for ...
