Phylogeography and evolutionary dynamics analysis of porcine delta-coronavirus with host expansion to humans.

From 2003 onwards, three pandemics have been caused by coronaviruses: severe acute respiratory syndrome coronavirus (SARS-CoV); middle east respiratory syndrome coronavirus (MERS-CoV); and, most recently, SARS-CoV-2. Notably, all three were transmitted from animals to humans. This would suggest that animals are potential sources of epidemics for humans.

Sparse-aperture photonics-integrated interferometer (SPIN) imaging system: structural design and imaging quality analysis.

The burgeoning field of astrophotonics, the interface between astronomy and photonics, is redefining astronomical instrumentation to replace traditional bulk optical systems with integrated optics. This drives the development of a new promising photonics-integrated interferometric imaging technique, called the segmented planar imaging detector for electro-optical reconnaissance (SPIDER). Compared to conventional imaging systems, SPIDER can reduce the size, weight, and power (SWaP) by one to two orders of magnitude for an equivalent imaging resolution in virtue of photonics-integrated technology.

The Meridian Tropism and Classification of Red Yeast Rice Investigated by Monitoring Dermal Electrical Potential.

Red yeast rice is a traditional Chinese medicine and food that has been purported to color food, ferment, and lower cholesterol. In order to study the antioxidative capacity of red yeast rice and the effects on electrical potential difference (EPD) of 12 acupuncture meridians, the pH value, oxidation reduction potential (ORP), ABTS, FRAP, T-SOD, and particle size distribution of red yeast rice were analyzed. 20 volunteers were recruited and randomly divided into two groups, the red yeast rice group (10 g red yeast rice and 40 g water) and control CK group (50 g water).

Effects of TAT-SOD at Acupoints on Essential Hypertension by Monitoring Meridians Electrical Potential.

Objectives: To investigate the effect on essential hypertension of the topical application of TAT-Cu, Zn-superoxide dismutase (TAT-SOD) at left acupoint Zusanli (ST 36), and to observe whether the change of electrical potential difference (EPD) can be related to the change of blood pressure.

Methods: Sixteen patients with essential hypertension and 16 healthy subjects were included in the study. EPD between the left acupoints of Yanglingquan (GB 34) and Qiuxu (GB 40) was firstly screened out for the EPD detection.

Topical Application of TAT-Superoxide Dismutase in Acupoints LI 20 on Allergic Rhinitis.

Reactive oxygen species are products of cellular metabolism and assigned important roles in biomedical science as deleterious factors in pathologies. In fact, some studies have shown that the therapeutic benefits of taking antioxidants were limited and the potential for therapeutic intervention remains unclear. New evidences showed that ROS have some ability of intercellular transportation.

[The development of FSCLZLY--an ascites-ultrafiltration instrument].

It's known to all that the refractory ascites treatment has so far been a very difficult clinical problem. We have extracted much experience from the practical techniques used in the refractory ascites treatments of more than 1,000 cases, and have developed the ascites ultrafiltration & concentration therapeutic instrument--FSCLZLY-A. The clinical applications show that it is very effective.

Capillary electrophoresis of erythrocytes.

Capillary electrophoresis (CE) of erythrocytes from different sources under various conditions is reported in this paper. It was found that erythrocyte samples from sheep, duck, and human showed characteristic and reproducible elution peaks, and that the retention times of A-, B-, AB-, and O-type erythrocytes from human blood were distinctively different; even subtle differences, among individuals with the same blood type could be detected by CE. A strictly linear correlation was obtained between the peak area and the amount of human erythrocyte over a range of 4.
