Uses of intravenous immunoglobulin
Adjuvant high dose IVIgs are being used increasingly in a range of immune-mediated and auto-immune diseases. Although numerous immunomodulatory mechanisms have been suggested, the exact mechanisms of action are poorly understood. The efficacy of IVIg in certain diseases has been proven in clinical trials, in so far as IVIg is approved as the therapy of choice for Kawasaki syndrome and idiopathi...
متن کاملUses of stable isotopes in clinical diagnosis and research in the paediatric population.
The landmark experiments of Schoenheimer and Rittenberg in the 1930s provided the scientific foundation for the ensuing development and application of stable isotope techniques in clinical diagnosis and research. Stable isotopes are non-radioactive atoms of the same chemical element, which diVer only in their number of neutrons. Many elements also have radioactive (non-stable) isotopes. Aspects...
متن کاملNatural abundance variations in stable isotopes and their potential uses in animal physiological ecology.
Chemical, biological, and physical processes lead to distinctive "isotopic signatures" in biological materials that allow tracing of the origins of organic substances. Isotopic variation has been extensively used by plant physiological ecologists and by paleontologists, and recently ecologists have adopted the use of stable isotopes to measure ecosystem patterns and processes. To date, animal p...
متن کاملThe uses of 'Uses of epidemiology'.
In 1944 the Association for Education in Citizenship published a pamphlet entitled ‘Health’ by Major Jerry Morris1 (of the Royal Army Medical Corps), as one of a series of Handbooks for Discussion Groups. The preface to the pamphlets in this series said that they were intended to be used by discussion circles concerned with the social, economic and political problems that arose from the Second ...
متن کاملLaser Separation of Isotopes
In nature most elements are mixtures of isotopes: they are made up of at oms that all have the same number of protons and electrons but that differ in number of neutrons. Ordinarily the fact that an element is a mixture of sev eral ·kinds of atoms matters little be cause the various isotopes are all but indistinguishable in most of their prop erties. For that very reason. however. when we d...
