Endocrinology and Metabolism Clinics of North America, 1991
It is now certain that both gonadotropins, LH and FSH, are synthesized, stored, and released within the circulation, and excreted as heterologous isoforms that can be distinguished by differences in their bioactive to immunoreactive potential and isoform distribution patterns. The bioactivity (which in this article has been defined as the ability of LH

Bioactive acetylenic metabolites
Phytomedicine, 2013This article focuses on anticancer, and other biological activities of acetylenic metabolites obtained from plants and fungi. Acetylenic compounds belong to a class of molecules containing triple bond(s). Naturally occurring acetylenics are of particular interest since many of them display important biological activities and possess antitumor ...

Peptides, 1995
Cyclic dipeptides are among the simplest peptide derivatives commonly found in nature. Most cyclic dipeptides found to date appear to have emerged as by-products of fermentation and food processing. However, many are endogenous to members of animal and plant kingdoms; these include cyclo(Pro-Leu), cyclo(Pro-Val), cyclo(Pro-Phe), cyclo(Ala-Leu), cyclo ...

Glutathione‐Dependent Bioactivation
Current Protocols in Toxicology, 2007AbstractThe classical view of the glutathione (GSH) conjugation pathway involves GSHS‐transferase (GST)‐dependent formation of thioether conjugates between GSH and an electrophilic substrate, processing to yield the corresponding cysteineS‐conjugate, which is then converted to anN‐acetylcysteine conjugate (or mercapturate).

Bioactivity evolution of the surface functionalized bioactive glasses
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2014AbstractThe formation of a calcium phosphate layer on the surface of the SiO2–CaO–P2O5 glasses after immersion in simulated body fluid (SBF) generally demonstrates the bioactivity of these materials. Grafting of the surface by chemical bonding can minimize the structural changes in protein adsorbed on the surface.

The in-vitro bioactivity of mesoporous bioactive glasses
Biomaterials, 2006Ordered mesoporous bioactive glasses (MBGs) with different compositions were prepared by using nonionic block copolymer surfactants as structure-directing agents through an evaporation-induced self-assembly process. Their in-vitro bioactivities were studied in detail by electron microscopy, Fourier-transform infrared spectroscopy, and inductively ...

Bioactivity of electro-thermally poled bioactive silicate glass
Acta Biomaterialia, 2009A 45S5 bioactive glass (nominal composition: 46.1 mol.% SiO2, 2.6 mol.% P2O5, 26.9 mol.% CaO, 24.4 mol.% Na2O) was electrothermally poled by applying voltages up to 750 V for 45 min at 200 degrees C, and the thermally stimulated depolarization currents (TSDCs) were recorded.

Poly (methylmethacrylate) (PMMA) bone cement, used to fix implants into the bone, produces good surgical results if used correctly. However, prostheses do eventually become loose and the breakdown of the cement mantle is a factor in this failure.
