Best Answer: For 1,1-dichloroethene, the 2 Cl atoms are both at one end-dipole. For cis-1,2-dichloroethene, the 2 Cl atoms are both on one side-dipole.But for trans-1,2-dichloroethene, the 2 Cl atoms are pulling electrons towards themselves on a line through the centre of the molecule, and there is no electron sift in any one direction overall.Source(s):Gervald F Â· 9 years ago.est Answer: For 1,1-dichloroethene, the 2 Cl atoms are both at one end-dipole. For cis-1,2-dichloroethene, the 2 Cl atoms are both on one side-dipole.
Activase Â® (alteplase) is indicated for treating patients with acute ischemic stroke, which is caused by a blood clot in the brainâs blood vessels.
Because it works on the clotting system, tPA (such as alteplase, reteplase, and tenecteplase) is used in clinical medicine to treat embolic or thrombotic stroke. Use is contraindicated in hemorrhagic stroke and head trauma. The antidote for tPA in case of toxicity is aminocaproic acid.t has been suggested that if tPA is effective in ischemic stroke, it must be administered as early as possible after the onset of stroke symptoms. Indeed, tPA has become widely considered standard of care in acute ischemic stroke, so long as the patient presents soon after the onset of stroke symptoms.
