Medical and Biological Physics.
Archives of Internal Medicine, 1969One year of college physics is usually sufficient to satisfy the physics prerequisites of the admission offices of most medical schools in the United States. As a result, the beginning resident in radiology, surgery, anesthesiology, or other disciplines concerned with basic physical principles is often faced with the consideration of fairly ...

Biological Physics—Origin and Perspectives [PDF]
ChemPhysChem, 2002 Biology and Physics share common ancestors. The two sciences have drifted apart during the last century, although they have often mutually fertilized each other. Often the discovery of a new physical method has triggered dramatic progresses in biology but there are also numerous examples of biology-inspired new developments in physics.

Physical and Biological Targeting of Radiotherapy
Acta Oncologica, 1999Targeting of radiotherapy can be based on improving physical dose distribution of radiation delivered or on utilization of specific biological processes for targeting. Tools for physical targeting include brachytherapy, hadron therapy, conformal radiotherapy, stereotactic radiotherapy, stereotactically guided conformal fractionated radiotherapy, and ...

The Physical and Biologic Properties of Cavit
The Journal of the American Dental Association, 1971The physical properties of Cavit and the response of dental pulp to this temporary filling material were tested. Cavit has a high linear expansion that apparently is caused by water sorption and that probably produces its sealing effect. Insertion of Cavit into dry cavity preparations caused aspiration of odontoblasts and an accompanying pain; no pain ...

The physical chemistry of biological membranes
Nature Chemical Biology, 2006Physical chemistry explains the principles of self-organization of lipids into bilayers that form the matrix of biological membranes, and continuum theory of membrane energetics is successful in explaining many biological processes. With increasing sophistication of investigative tools, there is now a growing appreciation for lipid diversity and for ...

On the physical origin of biological handedness
Origins of Life, 1979In the racemic conglomerate crystallization of over 1,000 samples of D,L-sodium-ammonium tartrate the effect of 32P beta irradiation on the weight, optical activity, and crystallite size was measured. Both weight and optical activity showed a statistical dependence on the intensity of beta irradiation.

Biological Influence of Physical Exercise on Hemostasis
Seminars in Thrombosis and Hemostasis, 2009Some of the benefits of physical activity may result from effects on hemostasis. However, the increased burden of cardiovascular complications and sudden death occurring during and immediately after exercise prompts investigation to elucidate the biological relationship between physical exercise and hemostatic function. Although both the hemostatic and

Physics of biological membranes
2006The biological membrane is a complex system consisting of an aqueous biomolecular planar aggregate of predominantly lipid and protein molecules. At physiological temperatures, the membrane may be considered a thin (∼50A) slab of anisotropic fluid characterized by a high lateral mobility of the various molecular components.

From physical to biological time
Mechanisms of Ageing and Development, 1988Time is a primitive (i.e. fundamental) notion, and the various concepts** that have been so far derived from this notion in various scientific domains do not cover all facets of it. Time in mechanics, either classical, quantal or relativistic, is devoid of directionality, the "arrow", i.e.
