A system of amber mutants has been developed for each of the T-even bacteriophages T2 and T6, to complement those already available in T4. In T2 these mutants identify 52 genes, of which 49 are homologous with T4 genes; in T6 they identify 45 genes, of which 42 have T4 homologs, and an additional one which is homologous to a T2 gene not yet identified in T4. In both T2 and T6, recombination bet...

The UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferase, designated GalNAc-T3, exhibits unique functions. Specific acceptor substrates are used by GalNAc-T3 and not by other GalNAc-transferases. The expression pattern of GalNAc-T3 is restricted, and loss of expression is a characteristic feature of poorly differentiated pancreatic tumors. In the present study, a sixth human UDP-GalNAc:poly...

INTRODUCTION Venous-to-arterial carbon dioxide difference (Pv-aCO2) may reflect the adequacy of blood flow during shock states. We sought to test whether the development of Pv-aCO2 during the very early phases of resuscitation is related to multi-organ dysfunction and outcomes in a population of septic shock patients resuscitated targeting the usual oxygen-derived and hemodynamic parameters. ...

Nonglucosylated T6 phage (T6gtam 16am30, hereafter called T6alpha gt-) were found to have two structural anomalies when compared with wild-type T6. The DNA of T6alpha gt- phage contains single-strand interruptions. These can be seen both during infection, in the pool of replicating DNA, and in DNA extracted from purified phage. In addition, the sodium dodecyl sulfate-polyacrylamide gel pattern ...

The 6-minute walk test (T6) is used to assess cardiopulmonary diseases due to its prognosis capacity, easy performance and reproducibility. Pulmonary hypertension (PH) is defined and classified as a hemodynamic consequence leading to increased pulmonary arterial pressure and may result in right ventricular failure and consequent death. This case reports the prescription of T6 by the cardiology ...

Phage T6 was used as a label to follow the growth of the outer membrane in a strain of Escherichia coli temperature sensitive for the production of the T6 receptor. Extension of the surface takes place at the cell poles. Small cells extend at only one pole, whereas larger cells grow from both poles. The change from unipolar to bipolar growth appears to depend on the attainment of a particular c...

Cell walls of E. coli strains B and Cullen contain specific receptors for colicin K and for the T2, T6, and C16 phages. The receptors for the bacteriocin and the T6 virus are located in the outer layers of the cell wall of these microorganisms and are absent in their cytoplasmic membrane. The receptors for colicin K, phage T2, and the T6 and C16 viruses differ in their stability toward enzymes ...

In this research work, an experimental evaluation was conducted to explore the fretting fatigue life of multilayer Cr–CrN-coated AL7075-T6 alloy specimens with higher adhesion strength to substrate as the coating adhesion strength is one of the most critical issues in magnetron sputtering technique. Physical vapor deposition (PVD) magnetron sputtering technique was used for coating purpose, and...
