Unwanted effects produced by d-tubocurarine result from a nonimmunemediated release of histamine from mast cells, leading to bronchospasm, urticaria, and hypotension. More commonly, a fall in blood pressure can be attributed to ganglionic blockade by d-tubocurarine. Pancuronium is a synthetic compound now frequently used and not likely to cause histamine release or ganglionic blockade.
Abciximab is a chimeric human-murine monoclonal antibody directed against GPIIb/IIIa that blocks the fibrinogen-binding site and thus prevents attachment of fibrinogen. The peptide derivatives, eptifibatide and tirofiban block GPIIB/IIIA competitively, more selectively and have a shorter effect than does abciximab.

 

Replication of the human immunodeficiency virus (HIV), the causative agent of AIDS, is susceptible to targeted interventions, because several virusspecific metabolic steps occur in infected cells (A). Viral RNA must first be transcribed into DNA, a step catalyzed by viral “reverse transcriptase. ”
ACh stimulates receptors located on the subsynaptic membrane of the second neuron. Activation of these receptors causes the nonspecific cation channel to open. The resulting influx of Na+ leads to a membrane depolarization.
