Assessment of acute toxicity is a necessary stage preclinical research the substance GIZh-298. The aim present study Methods. GIZh-298 was administered once intraperitoneally to mice at doses 200-330 mg/kg. Equivalent volume 1 % starch solution animals control groups. Periods intoxication and death with detailed description observed clinical picture were registered. Euthanasia pathoanatomical d...

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...

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...

Obesity is now recognized as a state of chronic low-grade inflammation and is called as metabolic inflammation. Delta-5 desaturase (D5D) is an enzyme that metabolizes dihomo-γ-linolenic acid (DGLA) to arachidonic acid (AA). Thus, D5D inhibition increases DGLA (precursor to anti-inflammatory eicosanoids) while decreasing AA (precursor to pro-inflammatory eicosanoids), and could result in synergi...
