Abstract:
... Conventional airborne virus measurement usually requires appreciable sampling and detection times. Viral aerosols should also be collected or prepared in a liquid medium whose volume typically ranges from milliliters to tens of milliliters; hence, many sampling and detection steps need to be taken with the unit horizontal or immobile. Moreover, viral aerosols need to be sufficiently enriched, whic ...

Abstract:
... The COVID-19 pandemic remains ever prevalent and afflicting—partially because one of its transmission pathways is aerosol. With the widely used central air conditioning systems worldwide, indoor virus aerosols can rapidly migrate, thus resulting in rapid infection transmission. It is therefore important to install microbial aerosol treatment units in the air conditioning systems, and we herein inv ...

Abstract:
... Microbial community assembly contributes to the restoration and rehabilitation of the disturbed ecosystems. However, the viral assembly mechanism and its difference from bacterial communities under soil contamination have not been previously reported. Here, clean, light and heavy chromium (Cr)-contaminated soils were collected from two Cr slag sites and adjacent soils in northwestern and southwest ...

Abstract:
... Since the last century, animal viruses have posed great threats to the health of humans and the farming industry. Therefore, virus control is of great urgency, and regular, timely, and accurate detection is essential to it. Here, we designed a rapid on-site visual data-sharing detection method for the Newcastle disease virus with smartphone recognition-based immune microparticles. The detection me ...
... Cyprinid herpesvirus 2 (CyHV-2) is a highly contagious pathogen that causes herpesviral haematopoietic necrosis (HVHN) disease to goldfish, Carassius auratus and gibel carp, C. auratus gibelio. In this study, the virus persistence or latency in apparently healthy farmed gibel carp and reactivation in vitro were investigated. All of the freshly dissected kidney tissues of 42 individuals of asymptom ...
... Hepatitis E virus (HEV) is the causative agent of hepatitis E. Some of the rise in hepatitis E infection in China may be linked to undercooked pork. In this study, we established a reverse transcription droplet digital PCR (RT-ddPCR) method to detect HEV in raw pork livers. The detection limit of the assay for HEV RNA was as low as 1.81 copies/μL. The suggested approach was validated on 14 samples ...

Abstract:
... Currently, the coronavirus disease 2019 (COVID-19) pandemic is ravaging the world, causing serious crisis in economy and human health. The top priority is the detection and drug development of the novel coronavirus. The gold standard for real-time diagnosis of coronavirus disease is the reverse transcription-polymerase chain reaction (RT-PCR), which is usually operatively complex and time-consumin ...

Abstract:
... The flowers of Trollius chinensis Bunge (Ranunculaceae) is a traditional Chinese medicine used to treat various inflammatory diseases, including upper respiratory infections, chronic tonsillitis, and pharyngitis. Recently, there has been growing research on the antiviral role of the flowers of T. chinensis Bunge. However, little is known about its anti-influenza virus effects and the underlying me ...
... During the coronavirus disease 2019 (COVID-19) pandemic, wastewater-based epidemiology (WBE) attracted attention as an objective and comprehensive indicator of community infection that does not require individual inspection. Although several severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detection methods from wastewater have been developed, there are obstacles to their social implem ...

Abstract:
... As a conserved protein degradation system, autophagy plays important roles in removing or degrading misfolded and denatured proteins to maintain the homeostasis in cells. As a core member of autophagy, the involvement of ATG8 in plant tolerance to abiotic stress is paid more attention. In this study, by the SMART online tool, the Atg8 conserved domain was detected in CaATG8e, and by the MEGA11 sof ...
... With rapid growing of environmental contact infection, more and more attentions are focused on the precise and absolute quantification of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus on cold chain foods via point-of-care test (POCT). In this work, we propose a hydrogel-mediated reverse transcription loop-mediated isothermal amplification (RT-LAMP) for ultrafast and absolute q ...
... Fish cell lines are important tools in many biological studies. Here, we established a new Japanese flounder brain (JFB) cell line from the brain tissue of the Japanese flounder (Paralichthys olivaceus), which was successfully sub-cultured for over 120 passages, and consisted predominantly of fibroblast-like cells. Sequencing of the actin gene confirmed that JFB cells were derived from the Japanes ...
... Pepper/Chilli leaf curl virus disease (PepLCVD/ChiLCVD) is the most destructive disease of pepper that seriously reduced pepper production. The LCVD is transmitted by vector whitefly (Bemisia tabaci) so efficiently that even single whitefly is able to transmit the virus. The effective way to manage the LCVD in pepper is to introduce LCVD resistance into agronomically desired cultivars, but the lac ...

Abstract:
... Epithelial cells are apico-basolateral polarized cells that line all tubular organs and are often targets for infectious agents. This review focuses on the release of human RNA virus particles from both sides of polarized human cells grown on transwells. Most viruses that infect the mucosa leave their host cells mainly via the apical side while basolateral release is linked to virus propagation wi ...

Infectious precocity virus (IPV) is a virus that results in slow growth and sexual precocity of farmed M. rosenbergii and causes significant economic losses. A TaqMan probe Quantitative Real-time PCR (qPCR) and a nested PCR assay for IPV ...

Abstract:
... The detection of infectious SARS-CoV-2 in food and food packaging associated with the cold chain has raised concerns about the possible transmission pathway of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in foods transported through cold-chain logistics and the need for novel decontamination strategies. In this study, the effect of electron beam (E-beam) irradiation on the inactiv ...

Abstract:
... Viruses have evolved numerous mechanisms to exploit the molecular machinery of their host cells, including the broad spectrum of host RNA-binding proteins (RBPs). However, the RBP interactomes of most viruses are largely unknown. To shed light on the interaction landscape of RNA viruses with human host cell RBPs, we have analysed 197 single-stranded RNA (ssRNA) viral genome sequences and found tha ...

Abstract:
... Protein microarray chips are composed of three components, these are pre-treatment substrates, surface chemical modification, and immobilizing protein on substrate surfaces. In this study, self-assembly monolayers are used for surface chemical modification. Using this method, silanization on a glass and silicon chip is achieved, forming the terminal group substrates. Modification of the substrate ...
... Growth tube collectors (GTCs) are used to sample virus aerosols because of their superior viable virus recovery among air samplers. However, a major limitation of such samplers is that they operate at low flow rates compared to many inertia-based air samplers. Herein, we demonstrated efficient measurements of airborne MS2 and T3 viruses using a GTC that can implement high flow velocities for highe ...
... α-Ketoamides have been found to be an important functional group in a broad spectrum of inhibitors such as the Corona virus and other viruses. Here we report an unprecedented gold-catalyzed 2-fold reaction of a bromoalkyne with anthranils. Hydrolysis of the initial product then directly leads to α-ketoamides. Water addition to the intermediate α-iminoimidoyl halides delivered α-ketoamides from a b ...
