一、破产可能的存在对公司价值有负面的影响。 二、但是,并非破产风险本身会降低(公司)价值 三、真正担心的是与破产相关的各种成本 四、这些成本是由股东来承担的

A recent study of controlled release of a model small-molecule drug from poly(lactide-co-glycolide) microspheres prepared by the single-emulsion method found that the diffusion constant of the drug through the polymer was best related to the polymers molecular weight according

1. Two hydrogels are prepared from two different candidate polymers for controlled release of a protein drug, interleukin-2(IL-2). The gels exhibit the same swelling ratio at equilibrium, but gel A(formed by cross-linked polymer A, repeat unit molecular weight Mo= 100 g/mole)has

The gels exhibit the same swelling ratio at equilibrium, but jel a (formed by cross-linked polymer A, repeat unit molecular weight Mo= 100 g/mole)has a molecular weight between cross-links of 3,000 g/mole, while gel B (formed from cross linked polymer B, Mo=95 g/mole) has a molecular weight between crosslinks of

1. An early study in the development of peptide-presenting biomaterials showed that polymer surfaces bearing RGD peptides at a density equivalent to -10 peptides per each cell was sufficient to promote cell attachment, spreading and subsequent cell growth. In contrast, when whole
