Antiparasitic efficacy of flavonoids identified from Psoralea corylifolia against Tetrahymena piriformis in guppy (Poecilia reticulate).

Tetrahymena piriformis belongs to the ciliated protists (ciliates), causing severe economic losses in aquaculture. Chemical drugs currently used usually have toxic side effects, and there is no specific drug against Tetrahymena. Therefore, it is an urgent need to identify new antiparasitic lead compounds.

Circ_0004104 participates in the regulation of ox-LDL-induced endothelial cells injury via miR-942-5p/ROCK2 axis.

Background: Cardiovascular disease was the most common disease among the elderly with high morbidity and mortality. Circ_0004104 was demonstrated to be involved in the regulation of atherosclerosis.

Methods: Quantitative real-time polymerase chain reaction was employed to measure the expression of circ_0004104, miR-942-5p and Rho associated coiled-coil containing protein kinase 2 (ROCK2).

First case of Coxiella burnetii infection in Palaemonetes sinensis cultured in Liaoning, China.

The Palaemonetes sinensis aquaculture industry in Panjin City, Liaoning Province, China, experienced heavy losses in October 2018. Morbidity of cultured shrimp reached 50% and was characterized by cloudiness of muscle and the gradual spread of disease within the population. When the infection was mild, histopathological examinations revealed that the muscle cells contained a considerable number of microorganisms.

Metschnikowia bicuspidata isolated from milky diseased Eriocheir sinensis: Phenotypic and genetic characterization, antifungal susceptibility and challenge models.

A severe disease occurred in farmed Eriocheir sinensis characterized by milky liquid accumulation in the pectoral cavity, in the province of Liaoning, China, during October 2018-April 2019. Diseased crabs moved sluggishly, exhibited appetite loss and readily lost legs. Under the microscopic analysis, it was observed that the milky liquid contained a large number of yeastlike microorganisms (0.

First case of non-O1/O139 Vibrio cholerae infection in the pink-tailed chalceus Chalceus macrolepidotus in China.

A pathogen was isolated from diseased pink-tailed chalceus Chalceus macrolepidotus during a high-mortality outbreak in a freshwater culture farm in Liaoyang, China. The diseased fish were characterized by disoriented behaviors, exophthalmos, and redness and swelling of the top of the head. A Gram-negative, pure strain of bacteria (CM0428) was isolated from the brain, kidney, and liver.

A Low-Cost, Ear-Contactless Electronic Stethoscope Powered by Raspberry Pi for Auscultation of Patients With COVID-19: Prototype Development and Feasibility Study.

Background: Chest examination by auscultation is essential in patients with COVID-19, especially those with poor respiratory conditions, such as severe pneumonia and respiratory dysfunction, and intensive cases who are intubated and whose breathing is assisted with a ventilator. However, proper auscultation of these patients is difficult when medical workers wear personal protective equipment and when it is necessary to minimize contact with patients.

Objective: The objective of our study was to design and develop a low-cost electronic stethoscope enabling ear-contactless auscultation and digital storage of data for further analysis.

Toward a national emission inventory for the catering industry in China.

Catering oil fumes are a major hazard to human health. In particular, the typical Chinese cooking style is characterised by a high temperature frying process that produces high levels of cooking oil fumes. However, limited data relating to this sector mean that national emission inventory data specific to the catering service industry do not exist.

Algorithm developed for dynamic quantification of coal consumption for and emission from rural winter heating.

Coal-dominated winter heating practices in China are largely accepted to be a leading cause of winter haze in the region though the amount of coal for heating is actually much lower than for power generation or industrial process. However, little is known about how the total rural coal weight in a region could be attributed to real time (e.g.

Study on Hesitant Fuzzy Information Measures and Their Clustering Application.

At present, research on hesitant fuzzy operations and measures is based on equal length processing, and an equal length processing method will inevitably destroy the original data structure and change the data information. This is an urgent problem to be solved in the development of hesitant fuzzy sets. Aiming at solving this problem, this paper firstly defines a hesitant fuzzy entropy function as the measure of the degree of uncertainty of hesitant fuzzy information and then proposes the concept of hesitant fuzzy information feature vector.

Ranolazine improves oxidative stress and mitochondrial function in the atrium of acetylcholine-CaCl2 induced atrial fibrillation rats.

Aims: Ranolazine, an antianginal agent used for chronic stable angina treatment, was demonstrated to be effective in atrial fibrillation (AF) treatment. The aim of this study was to explore the molecular mechanisms of its anti-AF effects.

Main Methods: AF rat model was established using acetylcholine (ACh)-CaCl2 injection for 7days followed by ACh infusion into the heart.
