'''[[Steroid|Steroids]]''', or '''steroid hormones''', are powerful hormones with drastic effects, both good and bad, when artificially supplemented into living systems.  They are normally produced by three glands, the adrenal cortex, the testes, and the ovaries, but are also produced by the placenta during pregnancy, and some steroids ("neurosteroids") are produced within the brain. Steroids play an important role at all stages of life from the embryo until death. Corticosteroids, or synthetic mimics such as [[prednisone]], are used to treat inflammation related illnesses like asthma or rheumatoid arthritis, but they can have severe side effects. Athletes have often taken anabolic steroids to improve muscle growth and athletic performance. Glucocorticoids play a role in metabolism and inflammation, and estrogens have been linked to cancer.  Testosterone and estrogen influence sexual traits (maleness/femaleness).  All steroid hormones are naturally synthesized from cholesterol (through pregnenolone) under the control of the [[anterior pituitary gland]], which produces [[andrenocorticotropic hormone]] (ACTH, or corticotropin), a polypeptide that stimulates the conversion of cholesterol to pregnenolone.
As an academic discipline, '''[[systems biology]]''' aims to explain, predict and control the properties, functions and behaviors of living [[system]]s &mdash; compartmented complex self-organized assemblages of interrelated components, naturally generated and naturally selected, interacting dynamically, coordinately and hierarchically, and exhibiting [[Emergence (Biology)|emergent]] properties, functions and behaviors &mdash; emergent in the sense of unique to the system-as-a-whole in comparison with those of its individuated components. Biological systems studied range from the level of the molecular subsystems of cells (e.g., mitochondrial production of versatilely usable energy; ribosomal protein synthesis; circuits of biochemical reactions regulating gene expression; cell-to-cell and within-cell signaling (communicational) pathways); to the Earth's biosphere, and include a large number of intermediate system levels (e.g., unicellular organisms, multicellular organs, multicellular organisms, ecosystems).

The '''[[Miniature Fox Terrier]]''' is a small, fine-boned, lightweight [[terrier]] developed as a [[hunting dog]] and [[vermin]] router. It is known colloquially in its native [[Australia]] as the “Mini Foxie”, the "Mini Fox Terrier" and sometimes as the “Little Foxie”.
The '''Basic Input Output System''' ('''[[BIOS]]''') is the part of many modern [[computer]]s responsible for basic functions such as controlling the [[keyboard]] or booting up an [[operating system]]. The term dates back to the original [[IBM]] personal computer of the early 1980's.
 
 
It is akin to the [[Toy Fox Terrier]], a breed that developed along similar lines in the [[United States of America|United States]].  Some Toy Fox Terrier owners can trace their dogs’ pedigrees to "Foiler", aka "Old Foiler", the first [[Fox Terrier]] registered by [[The Kennel Club]] in Britain, circa 1875-6. It is interesting that although the bloodlines of the Mini Foxie and the Toy Fox Terrier are apparently distinct, Australian and American dogs can bear startling resemblance to each other.  
The BIOS was an [[API]], located in non-volatile memory, and thus was said to be ''[[firmware]]''.  The BIOS [[chip]] in a personal computer originally provided an information-hiding layer between the (then) Disk Operating System ([[DOS]]) and the hardware.

"For a given level of detail, a roadmap represents (re-presents, or models) the structure of the system of roads... Systems biologists use maps, for example, to model the structure and interrelationships among biochemical molecules in cellular subsystems."

As an academic discipline, systems biology aims to explain, predict and control the properties, functions and behaviors of living systems — compartmented complex self-organized assemblages of interrelated components, naturally generated and naturally selected, interacting dynamically, coordinately and hierarchically, and exhibiting emergent properties, functions and behaviors — emergent in the sense of unique to the system-as-a-whole in comparison with those of its individuated components. Biological systems studied range from the level of the molecular subsystems of cells (e.g., mitochondrial production of versatilely usable energy; ribosomal protein synthesis; circuits of biochemical reactions regulating gene expression; cell-to-cell and within-cell signaling (communicational) pathways); to the Earth's biosphere, and include a large number of intermediate system levels (e.g., unicellular organisms, multicellular organs, multicellular organisms, ecosystems).

The Basic Input Output System (BIOS) is the part of many modern computers responsible for basic functions such as controlling the keyboard or booting up an operating system. The term dates back to the original IBM personal computer of the early 1980's.

The BIOS was an API, located in non-volatile memory, and thus was said to be firmware. The BIOS chip in a personal computer originally provided an information-hiding layer between the (then) Disk Operating System (DOS) and the hardware. [more...]
