according to webster and wind (1972) and anderson et al (1987), “organizational buying is a complex process and involves many people from different functional areas, multiple goals and potentially conflicting decision criteria. moreover, the customers of today are also more knowledgeable and selective when making their purchasing decisions. since a key to organizational survival is the retentio...
Antigen-specific factors produced by the T-cell growth factor-dependent T-cell continuous line E-9M(+) were partially purified. Gel analysis of the twice-affinity-purified eluate of a poly(Tyr,Glu)-poly(DLAla)--poly(LLys) [(T,G)-A--L] column revealed the existence of iodinated bands with molecular weights of 17,000 and 15,000, in addition to a diffuse band of high molecular weight. The specific...
Background and purpose: Regarding the high prevalence and adverse outcomes of unwanted pregnancies, this research was done on unwanted pregnant women referring to delivery department of Mazandran Medical Üniversity hospitals 1999-2000. Materials and methods: This research is a descriptive study done on 1200 unwanted pregnant women referring to delivery department of university hospitals in...
Mycobacterium tuberculosis (H37Rv strain) was used in this study. The bacterial cells were disintegrated by sonication. The separation and characterization of the soluble molecules were attempted by various techniques including gel filtration, ion exchange chromatographies and polyacrylamide gel electrophoresis, using SDS and 2ME. Eight protein molecules with molecular weights ranging from...
Low-molecular-weight retinol- and retinoic acid-binding proteins were shown to be present in the soluble fraction of human retinal tissue but absent from human fibroblasts grown in tissue culture. By the use of gel filtration and comparison with bovine retinal tissue, the human intracellular binding proteins were found to have molecular weights of approximately 17,000 daltons, which are compara...

Conjugation of methotrexate (MTX) (MW 454) with different molecular weights of polyethylene glycol (PEG) including methoxy-peg (mpeg) 750 D and 5000 D and diol-peg 35000 D led to compounds that are physicochemically highly different from the parent compound, MTX. In this study, an HPLC system consisting of C8 column and UV detector (?=342 nm), using a mixture of 30:70 v/v phosphate-citrate buff...
Lacking compliance with liquid intake restrictions is one of the major problems in patients on hemodialysis and causes an increased mortality. In 120 patients on hemodialysis with an average interdialytic weight gain (IWG) exceeding 1.5 kg on at least 2 days during the 4 weeks preceding the intervention, the effect of telemetric body weight measurement (TBWM) on IWG, ultrafiltration rate, and b...
