These findings suggest that AICAR may be a novel immunomodulator with promising beneficial effects for the treatment of respiratory viral infection in airway allergic diseases.

A single-feed wideband circularly polarized Spidron fractal slot antenna with a grooved dielectric resonator is presented. To realize a wideband axial ratio, the circular polarizations of both a Spidron fractal slot and a grooved rectangular dielectric resonator are merged. The proposed antenna is excited by a simple 50-Ω microstrip feed line which is located underneath the Spidron fractal slot. A prototype of the proposed antenna is fabricated and tested. The measured −10 dB reflection coefficient bandwidth and 3 dB axial ratio bandwidth are 40.33% (1.94-2.92 GHz) and 23.75% (2.30-2.92 GHz), respectively. The measured peak gain of the antenna is 4.23 dBic.

An open-loop per-pin skew compensation with lock fault detection is presented. The proposed circuit employs an open-loop reference selector, a two-stage open-loop delay lock method which is separated by a coarse and fine lock for fast lock-in time, and a fault lock detecting scheme to prevent lock fault by dead zone of samplers. A unidirectional scan method ahead the fine lock stage to minimise pinto-pin skew errors after calibration is also applied. The circuit was fabricated with 55 nm CMOS technology with a 1 V supply voltage and an area of 0.0036 mm 2 for one de-skewing module. The measured result shows that the skew error at 1 GHz operation was reduced to <6 ps after skew calibration when the skew between input/output (IO) pins was 230 ps, and the lock-in time was 11 clock cycles.
