This transparent cell transport service allows migration of ATM services to a PSN without having to provision the ATM subscriber or customer edge (CE) devices. The ATM CEs will view the ATM transparent cell transport service as if they were directly connected via a Time Division Multiplexer (TDM) leased line. This service is most likely to be used as an internal function in an ATM service provi...

hereditary ataxias are heterogeneous group of neurodegenerative disorders classified mainly into more than 40 autosomal dominant cerebellar ataxias and 50 recessive ataxias. large amount of nearly uncommon subtypes with extensive phenotypic overlap and relatively high rate of abnormal repetitive sequence expansions, such as trinucleotide repeat expansions make diagnostic genetic testing complic...

This report discusses the performance and sources of protocol overhead in ATM networks. It rst introduces ATM followed by a description of the inhouse ATM network. Our primary goal was to study the performance tradeoo of chosing TCP/IP versus ATM API in a local ATM network.

Ataxia-telangiectasia mutated (ATM) protein kinase regulates the DNA damage response (DDR) and is associated with cancer suppression. Here we report a cancer-promoting role for ATM. ATM depletion in metastatic cancer cells reduced cell migration and invasion. Transcription analyses identified a gene network, including the chemokine IL-8, regulated by ATM. IL-8 expression required ATM and was re...

The gene mutated in ataxia telangiectasia, ATM, on human chromosome 11q22-q23 is implicated in cell cycle control and DNA repair. Ataxia telangiectasia patients as well as ATM-deficient mice are immune deficient and develop lymphoproliferative disease. Abnormalities in 11q22.3-q23.1 have also been described in B-cell chronic lymphocytic leukemia (B-CLL). We analyzed B-CLL samples for loss of he...

Ataxia-telangiectasia mutated (ATM) plays crucial roles in DNA damage responses, especially with regard to DNA double-strand breaks (DSBs). However, it appears that ATM can be activated not only by DSB, but also by some changes in chromatin architecture, suggesting potential ATM function in cell cycle control. Here, we found that ATM is involved in timely degradation of Cdt1, a critical replica...
