This reconceptualization of continuity is especially relevant for young children, older persons and other dependent patients who rely on informal caregivers for health care.

...trophin, but it is still not clear why the muscles weaken and die. This work is to focus on one of the theories about this disease. This study is looking at possible changes in the outer layer, or membrane of the muscle cell where dystrophin is normally found. When dystrophin is absent, the muscle cell does...Purdue research offers hope for canine, human spinal injuries
... Trauma to nerve cells causes their membranes to weaken and even rupture. Though the cells may survive, this membrane damage causes them to lose the ability to produce and carry nerve impulses along their membranes from one cell to the next. "Worse yet, chemicals seeping out of the dying spinal c...New weapon in germ warfare: 'Jamming' bacteria signals stops cholera

Leukocytes are always present in the body, but most remain dormant until an immune response is activated by wounding or infection or until the brain identifies a stressful situation.
