A SOLUBLE CYTOTOXIC FACTOR FROM MACROPHAGES

Australian Journal of Experimental Biology and Medical Science, 1980
SummaryUnstimulated mouse peritoneal macrophages can lyse certain tumour cell lines via the action of a labile exotoxin, some of the properties of which are examined.

Soluble factors involved in glioma invasion

Acta Neurochirurgica, 2003
Recent studies using molecular and cellular techniques of the factors regulating the invasion process have revealed a crucial role for a number of growth factors and cytokines. Their function lies on the one hand in the autocrine stimulation of the tumor cells themselves, resulting in the stimulation of protease expression and an enhancement of ...

Soluble factors and solid phases

Current Biology, 1992
Macromolecules are constantly being transported between nucleus and cytoplasm in a selective, signal- dependent manner. This dynamic flux consists of the unidirectional transport of certain proteins and RNA molecules, and the bidirectional transport or ‘shuttling’ of other proteins and ribonucleoprotein particles.

Factors influencing aerosol solubility during cloud processes

Atmospheric Environment, 2001
The water-soluble fraction of an aerosol determines its chemical and physical properties and also its behaviour. The origin of the aerosol and its atmospheric transport influence its solubility. Cloud process simulations have been conducted on both Saharan and anthropogenic aerosols.

Bioconcentration factors and lipid solubility

Environmental Science & Technology, 1991
The log-log relationship between bioconcentration and hydrophobicity breaks down for several medium and high molecular weight solutes that bioconcentrate either to a small extent or not at all. Much of the failure is attributed to the relatively low solubility of these compounds in lipid.

Factors affecting lignin solubility

Russian Journal of Applied Chemistry, 2011
The solubility of lignin in aqueous NaOH solutions was studied in relation to the lignin molecular weight, temperature, liquid to solid ratio, and ionic strength. A new procedure for determining the content of phenolic hydroxyls in lignin was developed. A formula was suggested for calculating the lignin solubility in aqueous alkali solutions.
