Steroid biosynthesis is an anabolic metabolic pathway that produces steroids from simple precursors. A unique biosynthetic pathway is followed in animals compared to many other organisms, making the pathway a common target for antibiotics and other anti-infective drugs.teroid ring system: The parent ABCD steroid ring system (hydrocarbon framework) is shown with IUPAC-approved ring lettering and atom numbering. A steroid is an organic compound with four rings arranged in a specific configuration.
Intradiscal electrothermal therapy (IDET), also known as intradiscal electrothermal annuloplasty (IDTA) or IEA, is a minimally invasive surgical procedure that uses a catheter and a flexible electrode that is inserted into the affected disc in order to heat the entire posterior edge of the annulus.
Radiant heating is a technology for heating indoor and outdoor areas. Heating by radiant energy is observed every day, the warmth of the sunshine being the most commonly observed example. Radiant heating as a technology is more narrowly defined.It is the method of intentionally using the principles of radiant heat to transfer radiant energy from an emitting heat source to an object.Designs with radiant heating are seen as replacements for conventional convection heating as well as a way of supplying confined outdoor heating.t is the method of intentionally using the principles of radiant heat to transfer radiant energy from an emitting heat source to an object.
