Use of amphetamine sulfate to control appetite is contraindicated. High doses are toxic, and prolonged use may cause drug dependence.  

The rate of flow of electrons in an electrical circuit. Electric charge passing through a specific location within a specified timeframe can be measured using a unit known as an ampere. Remarkably, a single ampere corresponds to approximately 6.241 x 10¹⁸ electrons traversing a designated point along a wire within the span of a solitary…

A pore-forming protein used by Entamoeba histolytica to destroy red blood cell membranes. Amoebepores are localized in cytoplasmic vesicles and appear to destroy erythrocytes intracellularly rather than being released outside the cell to destroy host cells.  

A collection of fetal malformations associated with multiple fibrous strands of amnion that appear to develop or entangle fetal parts in utero. This leads to structural malformations and deformations and disruption of function. Defects associated with this condition include limb defects and amputations; abnormal dermal ridge patterns; simian creases; clubbed feet; craniofacial defects, including cleft…

Any animal or group belonging to the Amniota, a major group of vertebrates, the members of which develop an amnion. Included are reptiles, birds, and mammals.  

The instillation of fluid, usually normal saline, into the amniotic sac to increase the amniotic fluid volume. This is usually done by using a catheter passed through the cervix into the uterine cavity (or rarely, through the abdominal wall).
