Electroporation, the transient increase in the permeability of cell membranes when exposed to a high electric field, is an established in vitro technique and is used to introduce DNA or other molecules into cells. When the trans-membrane voltage induced by an external electric field exceeds a certain threshold (normally 0.2-1 V), a rearrangement of the(More)
The efficacy of all major insecticide classes continues to be eroded by the development of resistance mediated, in part, by selection of alleles encoding insecticide insensitive target proteins. The discovery of new insecticide classes acting at novel protein binding sites is therefore important for the continued protection of the food supply from insect(More)
Adipose tissue samples were biopsied from three subcutaneous sites in 80 obese and 27 non-obese patients. Additional samples were taken from intra-abdominal sites in 44 of the patients. There was a small increase in the calculated number of fat cells in the more obese patients, but there was no relation between fat-cell number and obesity of childhood(More)
