A Novel Coronavirus Disease (COVID-19): a Review of Host Cell Signaling Pathways.

Coronaviruses (CoVs) are the largest group of positive-sense RNA viruses. By increasing our understanding of the interactions between CoVs and the host innate immune system, we can evaluate the development and persistence of inflammation in the lungs and reduce the risk of CoV-induced lung inflammation with a new group of genetic variants. Here, we aim to discuss some recent changes in host cell factors that may be used by CoV to promote the proliferation cycle.

Effect of skin dielectric properties on the read range of epidermal ultra-high frequency radio-frequency identification tags.

This Letter presents an investigation of the effect of human tissue conductivity and permittivity on the performance of epidermal transfer tattoo ultra-high frequency radio-frequency identification (RFID) tags. The measurements were carried out on 20 individuals and the variations in the measured dielectric properties correlate well with variations in the measured tag read range on the individuals and to a lesser extent with their body mass index values. Simulation results also showed the effects of permittivity and conductivity on the designed resonance frequency of the RFID tag.

Alteration of local ACE activity and vascular responsiveness during development of 2K1C renovascular hypertension.

Objectives: This study sought to examine the correlation between development of hypertension and local, including; aorta, heart, kidney, lung, as well as circulatory (serum) ACE activity in two kidney one clip (2K1C) renovascular hypertension.

Methods: Ten- to twelve-week-old rats undertaken left renal artery clipping. Experiments were carried out in 2, 4, 8, and 12 weeks after induction of hypertension (2, 4, 8 and 12W).
