Guillain–Barré syndrome (also called "GBS") is a rapid-onset muscle weakness caused by the immune system damaging the peripheral nervous system. [3] Typically, both sides of the body are involved, and the initial symptoms are changes in sensation or pain often in the back along with muscle weakness, beginning in the feet and hands, often spreading to the arms and upper body.

In medicine, pleocytosis (or pleiocytosis) is an increased cell count (from Greek pleion, "more"), particularly an increase in white blood cell count, in a bodily fluid, such as cerebrospinal fluid. [1]
A second area of discussion surrounds the question of whether there is a qualitative or quantitative difference between dissociation as a defense versus pathological dissociation. Experiences and symptoms of dissociation can range from the more mundane to those associated with post traumatic stress disorder (PTSD) or acute stress disorder (ASD ...
The effects of dissociatives can include sensory dissociation, hallucinations, mania, catalepsy, analgesia and amnesia. [4] [5] [6] According to Pender (1972), "the state has been designated as dissociative anesthesia since the patient truly seems disassociated from his environment."
Dissociation is commonly displayed on a continuum. [18] In mild cases, dissociation can be regarded as a coping mechanism or defense mechanism in seeking to master, minimize or tolerate stress – including boredom or conflict. [19] [20] [21] At the non-pathological end of the continuum, dissociation describes common events such as daydreaming.
In chemistry, biochemistry, and pharmacology, a dissociation constant (K D) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its component ions.
Bovine serum albumin (BSA or "Fraction V") is a serum albumin protein derived from cows. It is often used as a protein concentration standard in lab experiments. The nickname "Fraction V" refers to albumin being the fifth fraction of the original Edwin Cohn purification methodology that made use of differential solubility characteristics of plasma proteins.
Dissociation, in the wide sense of the word, is an act of disuniting or separating a complex object into parts. Dissociation may also refer to: Dissociation (chemistry) , general process in which molecules or ionic compounds (complexes, or salts) split into smaller particles, usually in a reversible manner
