Plant tissue culture comprises a set of in vitro techniques, methods and strategies that are part of the group of technologies called plant biotechnology. Tissue culture has been exploited to create genetic variability from which crop plants can be improved, to improve the state of health of the planted material and to increase the number of desirable germplasms available to the plant breeder. ...

Anticomplement Immunofluorescence was used for antibody titration against varicellazoster virus (VZV) in 43 patients with peripheral facial palsy. Nine of 31 patients (29%) with Bell's palsy and eight of 12 patients (75%) with Ramsey-Hunt syndrome had anticomplement immunofluorescence antibody titres of > 1/10. On the other hand, none of 14 patients with herpes simplex virus (HSV) infection and...

Plants or plant cells in vitro, show physiological and morphological response to microbial, physical or chemical factors which are known as ‘elicitors’. Elicitation is a process of induced or enhanced synthesis of secondary metabolites by the plants to ensure their survival persistence and competitiveness. The application of elicitors, which is currently the focus of research, has been consider...

THE IMMUNOLOGY OF RHEUMATISM. By Jerzy B. Kwapinski and Marshall L. Synder. New York, Appleton-Century-Crofts, 1962. xii, 255 pp. $9.00. The immunology of rheumatism is a large field which is rapidly evolving. Any monograph on the subject will almost surely seem somewhat antiquated by the time it appears in print, and this monograph is no exception. Most of the references date from 1958 or earl...

1. A method of mass tissue culture has been devised by which, in a relatively short period of time, samples large enough for chemical isolation of mucopolysaccharides can be obtained. 2. Chemical isolation of acid mucopolysaccharides from mass cultures of human fetal skin, human fetal bone, bovine fetal skin, and rat subcutaneous tissue has been carried out. It has been found that the fibroblas...

Cultured tissues and cells are used extensively in physiological and pharmacological studies. In vitro cultures provide a means of examining cells and tissues without the complex interactions that would be present if the whole organism were studied. A number of special skills are required in order to preserve the structure, function, behavior, and biology of cells in culture. This unit describe...

Plant tissue culture, or the aseptic culture of cells, tissues, organs, and their components under defined physical and chemical conditions in vitro, is an important tool in both basic and applied studies as well as in commercial application. It owes its origin to the ideas of the German scientist, Haberlandt, at the beginning of the twentieth century. The early studies led to root cultures, em...

objective adult stem cells which are derived from different tissues, with their unique abilities to self-renew and differentiate into various phenotypes have the potential for cell therapy and tissue engineering. human adipose tissue is an appropriate source of mesenchymal stem cells with wide differentiation potential for tissue engineering research. in this study isolated stem cells from huma...
