Special Factors in Biological Strings
Journal of Theoretical Biology, 2000Biological macromolecules such as DNA, RNA, and proteins can be regarded as finite sequences of symbols (or words) over a finite alphabet. In this paper, we refer to DNA (RNA) sequences which are words on a four-letter alphabet. A comparison is made between some "genes", or fragments of them, with random sequences or random reshuffled sequences on the ...

Biological factors such as saliva, acquired dental pellicle, tooth structure and positioning in relation to soft tissues and tongue are related to dental erosion development. Saliva has been shown to be the most important biological factor in the prevention of dental erosion.

Biological and physiological factors in soybeans
Journal of the American Oil Chemists' Society, 1974There are limitations to which one is justified in drawing broad generalizations concerning the diverse biological and physiological effects of soy protein products. Nevertheless, there appear to be two distinct situations: (A.) Proper heat treatment exerts a beneficial effect upon the nutritive value of whole soybeans, full‐fat and defatted meal ...

Biological aspects of leukotactic factors
Journal of Allergy and Clinical Immunology, 1976Quantitation of leukotaxis involves direct visualization of migrated cells either as total cell numbers or according to depth of penetration of cells into filters. Newer approaches utilize radioactively labeled cells or movement in gel. Considerable controversy exists regarding the structural attributes of chemotactic activity, although synthetic ...

Biological Control of Factor VII
Thrombosis and Haemostasis, 1976SummaryThe tissue factor pathway is initiated by factor VII in the presence of tissue factor. The first proteolytic reaction involves cleavage of factor X by factor VII. Activated factor X, the product of this reaction, can activate factor VII by cleavage of a specific bond.

Biological factors in human sexuality
Journal of Sex Research, 2002This paper considers a number of key concepts relevant to biological determinants of human sexuality, including sexual differentiation, brain mechanisms involved in sexual response, the role of sex hormones, and the sexual effects of drugs. The paper concludes with consideration of how little is known about the interaction between biology and culture ...

Stereochemical Factors in Biological Activity
1959The property of many enzymes to attack one of a pair of stereoisomers selectively, ‘stereochemical specificity’, has been known for many years. In 1925, Cushny 1) wrote ‘the reactions of the enzymes to optically active isomers have been the subject of a large number of researches’.
