effects of fe and trichoderma harzianum bi strain on plant growth and development of spathiphyllum were investigated. experiments were carried out in an glasshouse and in pots filled with soil, perlite and coco peat (1:1:1) were used as the growing medium. plant roots (seedlings with three leaves) were inoculated with trichoderma (0 and 8% w/w) as media mixture. fe spray (0, 0.75, 1.5, 3 g/l), ...

OBJECTIVES To assess whether strain histograms are equal to strain ratios in predicting breast tumour malignancy and to see if either could be used to upgrade Breast Imaging Reporting and Data System (BI-RADS) 3 tumours for immediate biopsy. METHODS Ninety-nine breast tumours were examined using B-mode BI-RADS scorings and strain elastography. Strain histograms and ratios were assessed, and a...

The strain induced critical current degradation of overpressure processed straight Bi-2212/Ag wires has been studied at 77 K in self-field. For the first time superconducting properties, lattice distortions, composite wire stress and strain have been measured simultaneously in a high energy synchrotron beamline. A permanent Ic degradation of 5% occurs when the wire strain exceeds 0.60%. At a wi...

BACKGROUND An epidemic strain of Clostridium difficile designated by restriction endonuclease analysis (REA) as group BI has caused multiple outbreaks of severe C. difficile infection (CDI). The treatment response of patients infected with this strain is uncertain. METHODS Clostridium difficile isolates were collected from 2 phase 3 clinical trials comparing fidaxomicin to vancomycin and type...

Clostridium difficile strain BI/NAP1/027 is associated with increased C. difficile infection (CDI) rates and severity, and the efficacy of some CDI therapies may be strain dependent. Although cultured C. difficile isolates can be reliably subtyped by various methods, the long turnaround times, high cost, and limited availability of strain typing preclude their routine use. Nucleic acid amplific...

BACKGROUND North American and European hospitals have reported outbreaks of Clostridium difficile-associated disease with unexpectedly high mortality caused by a newly recognized group of C. difficile strains, group BI. Our objective was to compare, in hamsters, the virulence of a historical nonepidemic BI type, BI1, with that of 2 recent epidemic BI types, BI6 and BI17, and with that of 2 stan...

BACKGROUND The methylotrophic yeast Pichia pastoris is a well-studied host organism for recombinant protein production, which is usually regulated either by a constitutive promoter (e.g. promoter of glyceraldehyde-3-phosphate dehydrogenase; PGAP) or an inducible promoter (e.g. promoter of alcohol oxidase 1; PAOX1). Both promoter systems have several advantages and disadvantages; with one of the...
