A birth A fatty acid that is fully saturated with hydrogen atoms, and thus has no double bonds between its carbon atoms. Replacing saturated fats with unsaturated fats in the diet helps to lower the level of total cholesterol in the blood.caused by abnormal development of the neural tube, the structure which gives rise to the central nervous system. Neural tube defects include the absence of most/all of the brain (anencephaly) and a lack of protection of the spinal cord (spina bifida).
Damage to the nerves that control sensation (‘sensory nerves’). Symptoms include pain and numbness of the extremities and in severe cases, difficulty walking.
The liquid portion of blood, in which the blood cells are suspended. Serum is separated from blood cells using a centrifuge. Unlike blood plasma, serum lacks clotting factors because it is obtained from blood that has been allowed to clot.
Compounds that have the same molecular formula and sequence of bonded atoms, yet which differ in the three-dimensional orientations of their atoms in space. Stereoisomers may also differ in their potency.
A damage that occurs to a part of the brain when its blood supply is suddenly interrupted (‘ischemic stroke’) or when a blood vessel ruptures and bleeds into the brain (‘hemorrhagic stroke’). A stroke is also called a “cerebrovascular” accident.
(also known as a systematic overview)
A review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research, and to collect and analyze data from the studies that are included in the review.
The highest arterial pressure measured during the heart beat cycle, and the first number in a blood pressure reading (e.g.,120/80).
