The carbon monoxide transfer factor and its subdivisions, the pulmonary membrane diffusing capacity and the pulmonary capillary volume were measured in fourteen subjects following submassive pulmonary emboli, as demonstrated by a ventilation-perfusion scan, and in fourteen matched controls. Transfer factor and alveolar volume were significantly lower in patients with pulmonary emboli (p less th...

The precise manipulation of growth factor signaling is central to the progress of tissue engineering. Methods for direct time-resolved activation of signaling pathways through controlled receptor dimerization have been reported; however, these suffer from the risks associated with gene transfer. Here we present an alternative gene transfer-free approach in the form of a protein switch featuring...

Several distinct types of derepressed R factor mutants have been isolated and identified following nitrosoguanidine mutagenesis. One class of mutants appears to synthesize a temperature-sensitive repressor substance, as shown by the effects of temperature on R factor transfer, on male-specific phage sensitivity, and on F factor and Hfr transfer. In addition, two classes of repressor-in-sensitiv...

Cotes, J. E., Dabbs, J. M., Hall, A. M., Axford, A. T., and Laurence, K. M. (1973). Thorax, 28, 709-715. Lung volumes, ventilatory capacity, and transfer factor in healthy British boy and girl twins. Normal values are reported for the lung volumes, ventilatory capacity, and transfer factor of 212 healthy British twin children aged 8 to 16 years. The boys and the girls share a common relationshi...

background: heavy metals have detrimental effects on the health of human being. the values of manganese (mn) and lead (pb) in some plant species and soil samples in an arid area of iran were evaluated in this study. methods: the values of pb and mn in 94 plant samples from 8 plant species and the related soil samples in 2010 were considered in shahroud and damghan, central iran. moreover, the s...

The transfer of the OCT plasmid from Pseudomonas oleovorans to Pseudomonas putida strain PpGl results in the acquisition of three independent replicons: OCT, factor K, and the MER plasmid. OCT is a nontransmissible plasmid harboring genes that code for the enzymes responsible for the degradation of n-octane. Factor K is a transfer plasmid capable of mobilizing OCT as well as chromosomal genes b...

Temperature variations of the kinetics of the electrochemical and homogeneous oxidation of the title compounds give rise to Arrhenius plots, the slopes of which give access to the heavy-atom (including solvent) reorganization energies. Information on the role of proton transfer in the dynamics of the concerted proton-electron transfer reaction (CPET) is potentially contained in the pre-exponent...

Instance-based transfer learning methods utilize labeled examples from one domain to improve learning performance in another domain via knowledge transfer. Boosting-based transfer learning algorithms are a subset of such methods and have been applied successfully within the transfer learning community. In this paper, we address some of the weaknesses of such algorithms and extend the most popul...

without any doubt, one of the strategies to achieve knowledge-based economy is the transfer of high technologies and turning them into a competitive stable advantage for companies. technology readiness levels, as a determining factor for high-tech transfer, has not been taken into consideration in recent studies. in this paper the author seeks to identify and prioritize factors affecting the tr...
