Cell fusionCell fusion is an important cellular process in which several uninucleate cells (cells with a single nucleus) combine to form a multinucleate cell, known as a syncytium. Cell fusion occurs during differentiation of myoblasts, osteoclasts and trophoblasts, during embryogenesis, and morphogenesis. Cell fusion is a necessary event in the maturation of cells so that they maintain their specific functions throughout growth. In 1847 Theodore Schwann expanded upon the theory that all living organisms are composed of cells when he added to it that discrete cells are the basis of life.
Bath salts (drug)Bath salts (also psychoactive bath salts, PABS, or in the United Kingdom monkey dust) are a group of recreational designer drugs. The name derives from instances in which the drugs were disguised as bath salts. The white powder, granules, or crystals often resemble Epsom salts, but differ chemically. The drugs' packaging often states "not for human consumption" in an attempt to circumvent drug prohibition laws. Additionally, they may be mislabeled as plant food, powdered cleaner, and other such products.
Primary and secondary antibodiesPrimary and secondary antibodies are two groups of antibodies that are classified based on whether they bind to antigens or proteins directly or target another (primary) antibody that, in turn, is bound to an antigen or protein. A primary antibody can be very useful for the detection of biomarkers for diseases such as cancer, diabetes, Parkinson’s and Alzheimer’s disease and they are used for the study of absorption, distribution, metabolism, and excretion (ADME) and multi-drug resistance (MDR) of therapeutic agents.
Single Convention on Narcotic DrugsThe Single Convention on Narcotic Drugs, 1961 (Single Convention, 1961 Convention, or C61) is an international treaty that controls activities (cultivation, production, supply, trade, transport) of specific narcotic drugs and lays down a system of regulations (licenses, measures for treatment, research, etc.) for their medical and scientific uses; it also establishes the International Narcotics Control Board. The Single Convention was adopted in 1961 and amended in 1972.
