A new species of Streptocarpus (Gesneriaceae) endemic to Madagascar
(Museum Nationale d'Histoire Naturelle Paris, 2005-03)
A new species of Streptocarpus (S. lanatus MacMaster) is described from central
Madagascar. Material referable to this new taxon was previously assigned
to S. ibityensis Humbert, from which it can be distinguished by its ...
Screening of four Cyclopia (honeybush) species for putative phyto-oestrogenic activity by oestrogen receptor binding assays
(AOSIS OpenJournals, 2007)
Phyto-oestrogens mediate an oestrogenic effect through binding to the oestrogen receptor (ER) subtypes, ERα and ERβ. Four commercially available Cyclopia (honeybush) species - C. intermedia, C. subternata, C. genistoides ...
South African herbal teas : Aspalathus linearis, Cyclopia spp. and Athrixia phylicoides - a review
(Elsevier, 2008-10)
Rooibos (Aspalathus linearis (Brum.f) Dahlg.) and honeybush (Cyclopia Vent. species) are popular indigenous
South African herbal teas enjoyed for their taste and aroma. Traditional medicinal uses of rooibos in

Not all progestins are the same : implications for usage
(Elsevier, 2004-11)
Recent clinical evidence showing unexpected side-effects
of progestins used in contraception and hormone replacement
therapy has highlighted the importance of choice of
synthetic progestin. The molecularmechanisms of ...
Inhibition of cytochrome P450c11 by biogenic amines and an aziridine precursor, 2-(4-acetoxyphenyl_-2-chloro-n-methyl-ethylammonium chloride
(Informa Healthcare, 2000)
The interaction of several biogenic amines and Compound A (2-(4-acetoxyphenyl)-2-chloro- N-methyl-ethylammonium chloride), an analogue of the active substance in a HPLC fraction isolated from the shrub, Salsola tuberculatiformis ...
A dimer of the toll-like receptor 4 cytoplasmic domain provides a specific scaffold for the recruitment of signalling adaptor proteins
(Public Library of Science, 2007-08-29)
The Toll-like receptor 4 (TLR4) is a class I transmembrane receptor expressed on the surface of immune system cells. TLR4 is activated by exposure to lipopolysaccharides derived from the outer membrane of Gram negative ...
A fully dissociated compound of plant origin for inflammatory gene repression
(PNAS, 2005-11)
The identification of selective glucocorticoid receptor (GR) modifiers, which separate transactivation and transrepression properties, represents an important research goal for steroid pharmacology. Although the gene-activating ...
Evaluation of the phytoestrogenic activity of Cyclopia genistoides (honeybush) methanol extracts and relevant polyphenols
(American Chemical Society, 2007-04)
Unfermented C. genistoides methanol extracts of different harvestings and selected polyphenols were evaluated for phytoestrogenic activity by comparing binding to both ER subtypes, transactivation of an ERE-containing ...
Genetic susceptibility to tuberculosis in Africans : a genome-wide scan
(National Academy of Sciences, 2000)
Human genetic variation is an important determinant of the outcome of infection with Mycobacterium tuberculosis. We have conducted a two-stage genome-wide linkage study to search for regions of the human genome containing ...
