Background: Vascular endothelial growth factor (VEGF) has a key role in angiogene-sis and in transplantation. The level of VEGF is related to the differences in the DNA sequence of its promoter region. Objectives: In this study, the association between the combination of VEGF –1154 G and –2578 C alleles and VEGF production by LPS-stimulated PBMCs was investigated. In addition; the relationship ...

The production of colony-stimulating factors (CSF) is delicately controlled through a complex network of humoral and environmental factors. We have studied some of the mechanisms which regulate the production of CSF as compared to general protein synthesis in the lung tissue ill vitro. When lung tissue from mice was cultured for various times in serum free medium, the first detectable le...

The standard model of multinational production assumes that firms differ in Hicksneutral productivities and ignores differences in factor biases. Using a large firm-level dataset, I show that multinational firms differ from local firms in factor biases along two key dimensions. First, multinational firms are on average larger firms and larger firms on average use more capital-intensive technolo...

epidermal growth factor (egf), a growth factor involved in cell growth and differentiation, is a small polypeptide with molecular weight of approximately 6 kda known to be present in a number of different mammalian species. experimental studies in animals and humans have demonstrated that the topical application of egf accelerates the rate of epidermal regeneration of partial-thickness wounds a...

background haemophilus influenza may cause severe infections in children and adults. the isolation and identification of haemophilus spp. are not appropriately achieved in iran, while numerous infections are ascribed to the different members of this genus. lack of growth factors disks is our main shortage in this regard. materials and methods we obtained haemin (x-factor) from human blood, and ...
