Novel modified semi-carbonized fiber prepared using discarded clothes for derisking Cu(II) and Pb(II) contaminated water.

We report a novel modified semi-carbonized fiber (CF) prepared using cotton and acrylic clothes for derisking contaminated water to realize the resource utilization of discarded clothes in wastewater treatment. In this study, amphoteric and auxiliary modifiers were used to modify CFs for preparing amphoteric and amphoteric-auxiliary CFs. The basic physicochemical properties of different modified CFs were determined, and the microscopic morphology of modified CFs was detected.

Effect mechanism of litter extract from Alternanthera philoxeroides on the selective absorption of heavy metal ions by amphoteric purple soil.

Plant litter causes a serious waste of resources. Thus, plant litter extract (LE) should be used in the soil remediation of heavy metals. In this study, different proportions of LE from the Alternanthera philoxeroides were used to modify dodecyl dimethyl betaine (BS)-modified purple soil (P).

Isolation of a Novel Bat Rhabdovirus with Evidence of Human Exposure in China.

Bats are well-recognized reservoirs of zoonotic viruses. Several spillover events from bats to humans have been reported, causing severe epidemic or endemic diseases including severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2), SARS-CoV, Middle East respiratory syndrome-CoV (MERS-CoV), henipaviruses, and filoviruses. In this study, a novel rhabdovirus species, provisionally named Rhinolophus rhabdovirus DPuer (DPRV), was identified from the horseshoe bat (Rhinolophus affinis) in Yunnan province, China, using next-generation sequencing.

Stent insertion with high-intensity focused ultrasound ablation for malignant biliary obstruction: A protocol of systematic review and meta-analysis.

Background: This meta-analysis was conducted in order to understand the clinical efficacy of stent insertion with high-intensity focused ultrasound (HIFU) ablation for the treatment of malignant biliary obstruction (MBO).

Methods: The Pubmed, Embase, and Cochrane Library databases were searched for all relevant studies published through July 2020. The meta-analysis was conducted using RevMan v5.

Effect of Regulatory Network of Exosomes and microRNAs on Neurodegenerative Diseases.

Objective: A comprehensive review of the network regulation of exosomes and microRNAs (miRNAs) in neurodegenerative diseases was done, centering on the mechanism of the formation of exosomes and miRNAs and the sorting mechanism of exosomal miRNAs, with the aim to provide a theoretical basis in the search of biomarkers and the treatment of neurodegenerative diseases.

Data Sources: The comprehensive search used online literature databases including NCBI PubMed, Web of Science, Google Scholar, and Baidu Scholar.

Study Selection: The study selection was based on the following keywords: exosomes, miRNAs, central nervous system (CNS), and neurodegenerative diseases.

Injectable silicone rubber for ocular implantation after evisceration.

Objective: To investigate the usefulness of addition type liquid silicone rubber (ATLSR) as injectable implant after evisceration to maintain the eyeball volume in an animal experiment.

Methods: Twelve adult New Zealand white rabbits were included. One eye of each rabbit was randomly selected for evisceration with the fellow eye as control.

Diverse novel astroviruses identified in wild Himalayan marmots.

With advances in viral surveillance and next-generation sequencing, highly diverse novel astroviruses (AstVs) and different animal hosts had been discovered in recent years. However, the existence of AstVs in marmots had yet to be shown. Here, we identified two highly divergent strains of AstVs (tentatively named Qinghai Himalayanmarmot AstVs, HHMAstV1 and HHMAstV2), by viral metagenomic analysis in liver tissues isolated from wild Marmota himalayana in China.

[In vitro culture of tachyzoites of Toxoplasma gondii RH strain in HeLa cells].

Objective: To establish a stable and efficient in vitro culture model for tachyzoites of Toxoplasma gondii RH strain.

Methods: Tachyzoites were inoculated into HeLa cells to establish an in vitro culture system. The proliferation of tachyzoites was observed under microscope by the method of Giemsa stain.

[The possibility of hepatitis B virus transmission through dental handpieces].

Objective: To discuss the possibility of hepatitis B virus (HBV) transmission through dental handpieces.

Methods: Investigation was carried on methods for disinfecting and sterilizing dental handpieces and the condition of HBsAg contamination on dental handpieces before and after disinfection and sterilization by randomly sampling all special stomatological hospitals and dental clinics in a same city and 10 dental departments from the third, second and first class hospitals. The possibility of HBV transmission through dental handpieces was probed by investigating whether ducks can be infected by bath liquid of dental handpieces contaminated by DHBV, while in such bath liquid, DHBV can not be detected by serum dot hybridization.
