## Abstract This paper explores a relatively new methodology, the directional distance function method, to analyse productivity growth. The method allows us to explicitly evaluate the role that undesirable outputs of the economy, such as carbon dioxide and other greenhouse gases, have on the fronti

β¦ Synopsis
Many of the haemopoietic cell growth factors have now been purijied to homogeneity and their structural genes cloned. Methodr are also now available for obtainingpure populations of haemopoietic cells. The use of such cells, in combination with pure growth factors, has provided intriguing information about the biological activities and mode of action of the factors in facilitating survival, proliferation and diferen tia tion of the haemopoietic cells.

Mononuclear cells generate a variety of hormone-like proteins termed growth factors that are instrumental in the evolution and resolution of inflammatory reactions. Many of these growth regulatory molecules have multifunctional properties. For example, the mononuclear cell-derived growth factors, pl
A number of important neurotransmitter deficiencies have been described in Alzheimer's disease, the commonest cause of dementia in people at all ages. Particularly marked is the depletion of acetylcholine, and a number of treatments have been developed which are aimed at correcting this biochemical
The expression of neural regulatory molecules by immune cells that infiltrate the nervous system upon injury may be a mechanism for cross-regulation between the nervous system and the immune system. Several lines of evidence implicate nerve growth factor (NGF) signaling through its receptors (TrkA a
## Abstract Nerve growth factor (NGF) is a neurotrophic factor that plays an important role in the differentiation and growth of neuronal cells. It is also regarded as an inflammatory mediator in nonβneuronal tissues under physiological stress conditions. The mechanisms of NGF production and its ro
