A Haptoglobin-Like Glycoprotein is Produced by Implantation-Stage Rabbit Endometrium1

the window of implantation is closed by estrogen via insulin-like growth factor 1 pathway

background: the opening and closing of the implantation window is important for successful pregnancy in eutherians. the recent study demonstrated that the window of uterine receptivity was prepared by the sole action of progesterone in mice, but the mechanism to close the window remained to be elucidated. methods: the pregnant mice were ovariectomized on the evening on the third day of pregnanc...

Characteristics of a bacteriocin -like substance produced by Clostridium haemolyticum strain IRP - 135

Identification of a second collagen-like glycoprotein produced by Bacillus anthracis and demonstration of associated spore-specific sugars.

Certain carbohydrates (rhamnose, 3-O-methyl rhamnose, and galactosamine) have been demonstrated to be present in Bacillus anthracis spores but absent in vegetative cells. Others have demonstrated that these spore-specific sugars are constituents of the glycoprotein BclA. In the current work, spore extracts were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. A second col...

Protochlorophyll-like Pigment Produced by Rhodopseudomonas spheroides

The identification of intermediates in the biosynthesis of chlorophyll has been largely dependent upon the use ofmutants of Chlorella that are unable to synthesize chlorophyll but accumulate in the medium various tetrapyrrole compounds assumed to be precursors (for a review see Granick & Mauzerall, 1961). In particular, Granick (1950) identified magnesium vinylphaeoporphyrin a5 monomethyl ester...

Ferromagnetic Ga1ÀxMnxAs produced by ion implantation and pulsed-laser melting

We demonstrate the formation of ferromagnetic Ga12xMnxAs films by Mn ion implantation into GaAs followed by pulsed-laser melting. Irradiation with a single excimer laser pulse results in the epitaxial regrowth of the implanted layer with Mn substitutional fraction up to 80% and effective Curie temperature up to 29 K for samples with a maximum Mn concentration of x'0.03. A remanent magnetization...
