Biological Activity
In pharmacology, biological activity or pharmacological activity describes the beneficial or adverse effects of a drug on living matter. When a drug is a complex chemical mixture, this activity is exerted by the substance's active ingredient or pharmacophore but can be modified by the other constituents. Among the various properties of chemical compounds, pharmacological/biological activity plays a crucial role since it suggests uses of the compounds in the medical applications. However, chemical compounds may show some adverse and toxic effects which may prevent their use in medical practice. Activity is generally dosage-dependent. Further, it is common to have effects ranging from beneficial to adverse for one substance when going from low to high doses. Activity depends critically on fulfillment of the ADME criteria. To be an effective drug, a compound not only must be active against a target, but also possess the appropriate ADME (Absorption, Distribution, Metabolism, and ...

Bioactive Compound
A bioactive compound is a compound that has an effect on a living organism, tissue or cell, usually demonstrated by basic research in vitro or in vivo in the laboratory. While dietary nutrients are essential to life, bioactive compounds have not been proved to be essential as the body can function without them or because their actions are obscured by nutrients fulfilling the function. Bioactive compounds lack sufficient evidence of effect or safety, and consequently they are usually unregulated and may be sold as dietary supplements. Origin and examples Bioactive compounds are commonly derived from plants, animal products, or can be synthetically produced. Examples of plant bioactive compounds are carotenoids, polyphenols, or phytosterols. Examples in animal products are fatty acids found in milk and fish. Other examples are flavonoids, caffeine, choline, coenzyme Q, creatine, dithiolthiones, polysaccharides, phytoestrogens, glucosinolates, and prebiotics. In the diet The ...

Bioactive Glass
Bioactive glasses are a group of surface reactive glass-ceramic biomaterials and include the original bioactive glass, Bioglass®. The biocompatibility and bioactivity of these glasses has led them to be used as implant devices in the human body to repair and replace diseased or damaged bones. Most bioactive glasses are silicate based glasses that are degradable in body fluids and can act as a vehicle for delivering ions beneficial for healing. Bioactive glass is differentiated from other synthetic bone grafting biomaterials (eg. hydroxyapatite, biphasic calcium phosphate, calcium sulfate), in that it is the only one with anti-infective and angiogenic properties. History Discovery and development Larry Hench and colleagues at the University of Florida first developed these materials in 1969 and they have been further developed by his research team at the Imperial College London and other researchers worldwide. Hench began development by submitting a proposal hypothesis to the ...

Bioactive Paper
Bioactive paper is a paper-based sensor that can identify various contaminants in food and water. First developed in 2009, bioactive paper research has been ongoing and in 2011 was awarded a 5-year grant totalling $7.5 million CAD. It has been developed at the biosensor stage level, which means it can detect pesticides but is not yet able to repel and deactivate toxins. However, its ability to detect potential hazards has applications for human health and safety. The benefits of bioactive paper are that it is simple, portable, disposable, and inexpensive. Development Bioactive paper was developed by Canada’s Sentinel Bioactive Paper Network, a consortium of researchers, industrial and university, partners, and students. The Network is hosted by McMaster University in Hamilton, Ontario and is led by Dr. Robert Pelton, scientific director and Dr. George Rosenberg, managing director. John Brennan and his research team at McMaster University developed the method to create bioactiv ...
