We attempted to determine whether b1,3-galactosyltransferase b3Gal-T5 is involved in the biosynthesis of a specific subset of type 1 chain carbohydrates and expressed in a cancer-associated manner. We transfected Chinese hamster ovary (CHO) cells expressing Fuc-TIII with b3Gal-T cDNAs and studied the relevant glycoconjugates formed. b3Gal-T5 directs synthesis of Lewis type 1 antigens in CHO cel...

Objectives: The purpose of this study is to evaluate the anesthesia methods by observing hemodynamic changes, oxygen supply and demand balance in order to provide the reference for the Off-Pump Coronary Artery Bypass Grafting (OPCABG) anesthesia management level during OPCABG. Methods: Thirty patients scheduled for elective OPCABG were premedicated with intramuscular scopolamine 0.3 mg/kg and m...

This week we discuss a paper dealing with "Speculative Decoupled Software Pipelining". It bases on last week's paper, but due to the fact that DSWP is not mighty enough to parallelize many loops it expands this approach by using speculation. The problem that arises when certain loops are parallelized is that there are dependence recurrences inhibiting a parallelization using DSWP. To solve this...

Neuronal computation underlying detection of visual motion has been studied for more than a half-century. In Drosophila, direction-selective T4/T5 neurons show supralinear signal amplification in response to stimuli moving in their preferred direction, in agreement with the prediction made by the Hassenstein-Reichardt detector. Nevertheless, the molecular mechanism explaining how the Hassenstei...

BACKGROUND In the fly's visual motion pathways, two cell types-T4 and T5-are the first known relay neurons to signal small-field direction-selective motion responses [1]. These cells then feed into large tangential cells that signal wide-field motion. Recent studies have identified two types of columnar neurons in the second neuropil, or medulla, that relay input to T4 from L1, the ON-channel n...

Four site-specific endodeoxyribonucleases have been partially purified from extracts of bacteriophage T5-infected Escherichia coli by gel filtration and affinity chromatography on single- and double-stranded DNA. The enzymes were detected and characterized by agarose gel electrophoresis of alkali-denatured digestion products. None of the four is found in uninfected cells. In the presence of a d...

Bacteriophage T5 induces a deoxyuridine 5'-triphosphate nucleotidohydrolase (dUTPase) activity during infection of Escherichia coli. A T5 mutant (T5 dut) unable to induce this dUTPase activity has been isolated. Although this mutant is viable, the E. coli dUTPase activity is not sufficiently active to exclude uracil from the progeny DNA and about 3% of the thymine is replaced by uracil. When th...

Overview The Terminator 5 (T5) ASIC from Chelsio Communications, Inc. is a fifth generation, highperformance 2x40Gbps/4x10Gbps server adapter engine with Unified Wire capability, enabling offloaded storage, compute and networking traffic to run simultaneously. T5 also provides a full suite of high performance stateless offload features for both IPv4 and IPv6. In addition, T5 is a fully virtuali...

The gene D5 product (gpD5) of bacteriophage T5 is a DNA-binding protein that binds preferentially to double-stranded DNA and is essential for T5 DNA replication, yet it inhibits DNA synthesis in vitro. Mechanisms of inhibition were studied by using nicked DNA and primed single-stranded DNA as a primer-template. Inhibition of T5 DNA polymerase activity by gpD5 occurred when double-stranded regio...

Bacteriophage T5 induces a deoxyuridine B’-triphosphate nucleotidohydrolase (dUTPase) activity during infection of Escherichiu coli. A T5 mutant (T5 dut) unable to induce this dUTPase activity has been isolated. Although this mutant is viable, the E. coli dUTPase activity is not sufficiently active to exclude uracil from the progeny DNA and about 3% of the thymine is replaced by uracil. When th...
