Three species of Freycinetia (Pandanaceae) (F. reineckei, F. storkii, and F. hombronii) were tested for oviposition preference of Ochlerotatus samoanus, a vector of filariasis in Samoa. Laboratory tests indicated that F. reineckei was preferred by this mosquito for oviposition. Eggs were preferentially deposited on a peeled or a moist dried leaf. The percentage hatch was highest when eggs were ...

Xyloglucan is a key polymer in the walls of growing plant cells. Using split pea stem segments and stem segments from which the epidermis had been peeled off, we demonstrate that the integration of xyloglucan mediated by the action of wall-bound xyloglucan endotransglycosylase suppressed cell elongation, whereas that of its fragment oligosaccharide accelerated it. Whole xyloglucan was incorpora...

Experiments are described which provide a direct measure of the adhesion between dermis and epidermis during the development of feather primordia in chick dorsal skin in culture. The epidermis was peeled from the dermis and the surfaces so exposed were examined under the scanning electron microscope: regions of strong adhesion between the tissues were revealed as areas where their separation wa...

Ekbom Syndrome is characterized by delusion that small living being infests skin. The clinical profile of this disorder has shown it to be associated with organic conditions. Neuroimaging studies implicate putamen as the brain structure involved in the pathophysiology. These are also known as organic delusional disorder and provide an opportunity to study biological causation of delusional diso...

We studied the most superficial layer of macroscopically normal articular cartilage obtained from human femoral heads, using polarising microscopy and SEM. The most superficial layer, 4 to 8 microns thick, was acellular consisting of collagen fibrils. This layer could be peeled away as a thin film, with no broken collagen fibrils on its inferior surface or on the surface of subjacent cartilage ...

The aim of the “ARTEMIS” project is to investigate the ageing mechanisms for cross-linked polyethylene under thermo-electrical stress and to identify ageing markers, which can be used to carry out diagnostic procedures. A carefully selected set of techniques which can give cross-correlated information on space charge phenomenology and material degradation were used to investigate specimens peel...
