necrobiotic granuloma
28 January 2020collagenolytic granuloma
Definition : Granulomatous disorders comprise a large family sharing the common histological denominator of granuloma formation. Collagenolytic or necrobiotic granuloma is one in which a granulomatous infiltrate develops around a central area of altered collagen and elastic fibers.
The altered fibers exhibit new staining patterns, becoming either more basophilic which gives blue appearance (“blue granuloma”) or eosinophilic giving red appearance (“red granuloma”). (...) -

AL amyloidosis
28 September 2019WKP
Definition : Amyloid light-chain (AL) amyloidosis, also known as primary amyloidosis, is the most common form of systemic amyloidosis in the US.
The disease is caused when a person’s antibody-producing cells do not function properly and produce abnormal protein fibers made of components of antibodies called light chains. These light chains come together to form amyloid deposits which can cause serious damage to different organs.
Abnormal light chains in urine are sometimes referred (...) -
AA amyloidosis
28 September 2019WKP
AA amyloidosis is a form of amyloidosis, a disease characterized by the abnormal deposition of fibers of insoluble protein in the extracellular space of various tissues and organs. In AA amyloidosis, the deposited protein is serum amyloid A protein (SAA), an acute-phase protein which is normally soluble and whose plasma concentration is highest during inflammation. -
living systems
29 December 2018living system
Definition : Living systems are open self-organizing life forms that interact with their environment. These systems are maintained by flows of information, energy and matter.
Some scientists have proposed in the last few decades that a general living systems theory is required to explain the nature of life.
Such a general theory, arising out of the ecological and biological sciences, attempts to map general principles for how all living systems work.
Instead of examining (...) -

organ functions
4 February 2018Organ functions
Definition : Function of an organ in organ systems.
Organ systems
The notion of system (or apparatus) relies upon the concept of vital or organic function / organ functions : organ systems are a set of organs with a definite function.
The enumeration of the principal functions - and consequently of the systems - remained almost the same since Antiquity, but the classification of them has been very various, e.g., compare Aristotle, Bichat, Cuvier.
The notion of (...)
