Escitalopram improves neural functional prognosis and endothelial dysfunction in patients with acute cerebral infarction.

Background: Escitalopram is one of the most commonly used SSRIs at present, which has the characteristics of quick onset, less interactions with other drugs, and relative safety.

Objective: This study aims to investigate the effects of escitalopram on neural functional prognoses and endothelial dysfunction after acute ischemic stroke.

Methods: One hundred eligible patients afflicted with acute ischemic stroke were randomized into two groups: control and treatment groups.

Effects of the prophylactic use of escitalopram on the prognosis and the plasma copeptin level in patients with acute cerebral infarction.

This study aimed to investigate whether the routine administration of escitalopram for three months would improve the prognosis of patients with ischemic stroke and decrease the plasma copeptin level. A total of 97 patients with acute cerebral infarction were randomly allocated to receive escitalopram (5-10 mg once per day, orally; n=49) or not to receive escitalopram (control group; n=48) for 12 weeks starting at 2-7 days after the onset of stroke. Both groups received conventional treatments, including physiotherapy and secondary prevention of stroke.

Experimental Array for Generating Dual Circularly-Polarized Dual-Mode OAM Radio Beams.

Recently, vortex beam carrying orbital angular momentum (OAM) for radio communications has attracted much attention for its potential of transmitting multiple signals simultaneously at the same frequency, which can be used to increase the channel capacity. However, most of the methods for getting multi-mode OAM radio beams are of complicated structure and very high cost. This paper provides an effective solution of generating dual circularly-polarized (CP) dual-mode OAM beams.

[Photoluminescence of nano-SiC annealed by pulse laser].

Nanocrystalline silicon carbon (nc-SiC) from amorphous silicon carbon films was obtained through XeCl excimer laser annealing. The photoluminescence (PL) of the nc-SiC was analyzed at different annealing laser energy density. It was observed that PL presented a wide luminescence band from 300-600 nm in the nc-SiC films.
