Lactobacillus bulgaricus LT4(0448) is a lysogenic strain from which a temperate bacteriophage can be induced by mitomycin C or UV irradiation. Lactobacillus lactis CNRZ 326 is an indicator strain for the temperate phage 0448, but this strain lyses only in the presence of Ca ions. A resistant culture developed secondarily after phage lysis and grew normally in MRS broth but again lysed abruptly ...

OBJECTIVES Gram-negative bacteria with diverse carbapenemases, including New Delhi metallo-β-lactamase (NDM) enzymes, have been increasingly recorded in the UK since 2007. We analysed patient data for NDM-positive isolates confirmed by the national reference laboratory from UK laboratories from February 2008 to July 2013. METHODS Isolates resistant to carbapenems and with imipenem MICs reduce...

We studied the effect of pH on ligand binding in wild-type lactose permease or mutants in the four residues-Glu-269, Arg-302, His-322, and Glu-325-that are the key participants in H(+) translocation and coupling between sugar and H(+) translocation. Although wild-type permease or mutants in Glu-325 and Arg-302 exhibit marked decreases in affinity at alkaline pH, mutants in either His-322 or Glu...

BACKGROUND A four-amino acid deletion was identified within the alpha 2C-adrenergic receptor (alpha 2C Del322-325) that, when homozygous, increases the risk of heart failure in African-Americans nearly six-fold. We hypothesised that homozygosity for the alpha 2C Del322-325 polymorphism may be a risk factor for heart failure due to idiopathic dilated cardiomyopathy (DCM) in black South Africans....

Lesion of toxemia in first trimester pregnan­cies: Lesion of toxemia of pregnancy, compris­ing desidual arteriolar thickening, narrowing, degeneration, and endothelial vacuolization with trophoblastic degeneration and fibrin thrombi attached to degenerated chorionic villi, were evident in 46 (14.1 per cent) of 326 induced first trimester abortioruJ. No clinical features of toxemia were present,...

The effects of infection by tobacco cyst nematode (Globodera tabacum solanacearum) on growth of flue-cured tobacco cultivars NC 567 (resistant) and K 326 (susceptible) were evaluated in the field in 1993 and 1994. Infection by G. t. solanacearum suppressed number of leaves, plant height, and fresh weight of leaves and feeder roots. Correlations between weekly egg densities of G. t. solanacearum...

Peptides are valuable tools for studying protein-protein interactions, especially in cases of isolated protein domains and natively unfolded proteins. Here, we used peptides to quantitatively characterize the interaction between the natively unfolded HIV-1 Tat protein and the tetramerization domain of the cellular tumor suppressor protein p53. We used peptide mapping, fluorescence anisotropy, a...

BACKGROUND/AIMS A disintegrin and metalloprotease (ADAM) 17 has been reported to be implicated in cancer cells invasion. Nevertheless, its potential role in lung adenocarcinoma has not been addressed clearly. METHODS RT-PCR and Western blot were used to detect the expression of miR-326 and ADAM17 in lung adenocarcinoma samples (n=73). miR-326 mimics and inhibitor were tansfected in human A549...
