The biologic activity of selenoestrogens
Canadian Journal of Biochemistry, 1982For differential imaging of mammary tumors with estrogen receptors and without estrogen receptors we required γ-emitting estrogen analogues. In this paper we report on the binding properties of 7α-, 16α-, and 17α-methylselenoestrogens and 17α-phenylselenoestrogens relative to the binding properties of estradiol.The selenium-containing estrogens ...

Biological Activity of Silatranes
1978About 15 years ago we discovered high toxicity and specific biological activity of 1-arylsilatranes (1, 2) which, at that time, belonged to an almost unknown class of heterocyclic derivatives of penta-coordinate silicon with general formula (Fig. 1).

Biological Activities of Complement
Biochemical Society Transactions, 1978Complement is a system of serum proteins whose main function is to defend the body against infection. Although it has a reputation as a dauntingly complex system, this results chiefly from confusion in the nomenclature, which has varied considerably with time as more components were discovered, for example as ‘component C3’ became subdivided into ...

Biological Activity of Purpurogallin
Bioscience, Biotechnology, and Biochemistry, 1997Purpurogallin showed antibacterial activity toward gram-positive bacteria. Strong activity against methicillin-resistant Staphylococcus aureus [minimal inhibitory concentration (MIC) against methicillin of 1600 micrograms/ml] was found, with MIC of 11.0 micrograms/ml. Purpurogallin inhibited the growth of all tested plants and decreased the chlorophyll

Biological Activities of Alginate
2014To gain insight into the structure-activity relationship of alginate, we examined the effect of alginates with varying molecular weights and M/G ratio on murine macrophage cell line, RAW264.7 cells in terms of induction of tumor necrosis factor-α (TNF-α) secretion. Among the alginates tested, alginate with the highest molecular weight (MW 38,000, M/G 2.

Biological Activity of Calcitriol
Archives of Pediatrics & Adolescent Medicine, 1987Sir .—I read with interest the article by Venkataraman et al 1 in the October issue of AJDC . After reading their explanations and examining Fig 2, which did not indicate any dose-dependent calcium response to parenteral administration of 1,25-dihydroxyvitamin D, I wonder about the biological activity of the calcitriol that the authors used.

Biological Activities of Carrageenan
2014Red seaweeds are popular and economically important worldwide and also well known for their medicinal effects due to the presence of phycocolloids. Carrageenans, the major phycocolloid group of red algae, have been extensively investigated for their vast array of bioactivities such as anticoagulant, antiviral, cholesterol-lowering effects ...
