Pediatric glioblastomas (GBM) including diffuse intrinsic pontine gliomas (DIPG) are devastating brain tumors with no effective therapy. Here, we investigated clinical and biological impacts of histone H3.3 mutations. Forty-two DIPGs were tested for H3.3 mutations. Wild-type versus mutated (K27M-H3.3) subgroups were compared for HIST1H3B, IDH, ATRX and TP53… (More)
We report the first demonstration of 340 Gb/s, 50 GHz DWDM straight-line transmission over 6380 km with performance fully consistent with transatlantic plant installation.
Slanted Bragg grating and fiber were specially designed for erbium amplifier gain flattening. Results on 11 cascaded 50-km amplified spans show 0.1 dB gain excursion per amplifier on bandwidth as wide as 17.8 nm.
Epigenetic modifications of DNA, such as 5-methylcytosine and 5-hydroxymethycytosine, play important roles in development and disease. Here, we present a cost-effective and versatile methodology for the analysis of DNA methylation in targeted genomic regions, which comprises multiplexed, PCR-based preparation of bisulfite DNA libraries followed by… (More)
Patients with multiple sclerosis (MS) from the two Montreal MS clinics, were divided into two groups: one group of 61 patients (MS type I) who had no clinical history of susceptibility to recurrent respiratory tract infections and a second group of 58 patients (MS type II) who had persistent susceptibility to such infections since childhood. All patients… (More)
Pilocytic astrocytoma (PA) is the most common brain tumor in children but is rare in adults, and hence poorly studied in this age group. We investigated 222 PA and report increased aneuploidy in older patients. Aneuploid genomes were identified in 45% of adult compared with 17% of pediatric PA. Gains were non-random, favoring chromosomes 5, 7, 6 and 11 in… (More)
