[Intravenous thrombolytic therapy of ischemic stroke with the drug Revelisa in real clinical practice: results of the IVT-AIS-R study].

Objective: Evaluation of the safety and effectiveness of thrombolytic therapy (TLT) with the drug Revelisa (alteplase) in patients with ischemic stroke (AI) in real clinical practice.

Material And Methods: An open prospective multicenter non-interventional register study was conducted, which included 550 patients with AI - 259 (47.1%) women and 291 (52.

Boosted excitation of the fifth cyclotron harmonic based on frequency multiplication in conventional gyrotrons.

We discovered a specific property of the eigenmodes of a cylindrical waveguide, due to which efficient mode excitation at ultrahigh (s=4n+1, n is integer) multiples of the gyrofrequency can be provided by a polyhelical weakly relativistic electron beam, standardly used for gyrotron operation. In the proof-of-principle experiment with a V-band gyrotron driven by a 25-keV, 2-A beam, about 100 mW radiation power at the fifth cyclotron harmonic (0.22 THz) has been detected in the cw regime.

[Nonimmunogenic staphylokinase in the treatment of acute ischemic stroke (FRIDA trial results)].

Aim Of The Study: To investigate the efficacy and safety of non-immunogenic staphylokinase (NS) compared with alteplase (A) in patients with acute ischemic stroke (AIS) within 4.5 h after symptom onset.

Material And Methods: 336 patients with IS within 4.
