It is estimated that coronary heart disease (CRD) and cerebrovascular diseases are responsible for between 40-50% of all deaths. Righ blood pressure is common in all industrialized societies and contributes importantly to CRD. It is

Lippert there is evidence that filamentous surface structures on the bacteria, called pili or fimbriae, are the adhesins that bind to epithelial cells of the host. The adhesins interact with complementary receptors which are carbohydrate-containing polymers on the target cells. The importance of adhesion i

We have recently studied the molecular size and conformation of pea chloroplast (ct-)DNA by renaturation kinetics and electron microscopy (KOLODNER & TEWARI 1972). The ct-DNA was found to denature with a sharp

D. Van der Waaij,H. G. de Vries-Hosperstially offers a fast means for generating, evaluating and selecting genotypes with superior salt tolerance. Furthermore, little space is required and the environment can be controlled. However, plants regenerated from selected cells have not shown unequivocal increases in salt tolerance. Clearly the
