Low-pathogenic human coronaviruses (HCoVs) infect the upper respiratory tract and cause mild, cold-like respiratory illness. Although several studies have shown evidence of the global distribution of HCoVs, information about their distribution in Italy are often focused only on hospitalized children and elderly with respiratory symptoms. In this study, a total of 916 swab samples collected during the first two SARS-CoV-2 pandemic waves in Abruzzo region (central Italy) was selected for molecular screening of low pathogenic HCoVs by real-time RT-PCR. We identified low-pathogenic HCoV in nine samples. Positive samples underwent whole genome sequencing for genome characterization; indeed, we also report the whole genome sequence of a HCoV-229E strain.

Point-of-care testing methods are essential for the large-scale diagnosis and monitoring of bacterial infections. This study introduces an integrated platform designed for the simultaneous detection of pathogenic bacteria. Users can simply inject samples into the system, which then conducts the entire procedure in a fully automated manner, eliminating the need for external power sources, all within 60 min or less.

Background: Genomic analysis has revealed extensive contamination among laboratory-maintained microbes including malaria parasites, Mycobacterium tuberculosis, and Salmonella spp. Here, we provide direct evidence for recent contamination of a laboratory schistosome parasite population, and we investigate its genomic consequences. The Brazilian Schistosoma mansoni population SmBRE has several distinctive phenotypes, showing poor infectivity, reduced sporocyst number, low levels of cercarial shedding and low virulence in the intermediate snail host, and low worm burden and low fecundity in the vertebrate rodent host.

Objective: To investigate the effects of discordant medication beliefs on diabetes self-management and glycemic control in older Black individuals with diabetes and Mild Cognitive Impairment (MCI).
Methods: Cross-sectional analysis of baseline data from two clinical trials testing behavioral interventions to improve glycemic control in older Black primary care patients with diabetes and MCI.
Results: The mean number of discordant medication beliefs was 6 (SD = 3; range 0 to 16).

Excessive inflammatory responses to viral infections, known as cytokine storms, are caused by overactivation of endolysosomal Toll-like receptors (TLRs) (TLR3, TLR7, TLR8, and TLR9) and can be lethal, but no specific treatment is available. Some quinoline derivatives with antiviral activity were tried during the recent coronavirus disease 2019 (COVID-19) pandemic, but showed serious toxicity, and their efficacy for treating viral cytokine storms was not established. Here, in order to discover a low-toxicity quinoline derivative as a candidate for controlling virally induced inflammation, we synthesized a series of derivatives of amodiaquine (ADQ), a quinoline approved as an antimalarial, and tested their effects on TLRs-mediated production of inflammatory cytokines and cell viability in vitro.

Compared to conventional polymer-based and biomaterial carriers, cells as vehicles for delivering bioactive molecules in the treatment of tumor diseases offer characteristics such as non-toxicity, biocompatibility, low immunogenicity, and prolonged in vivo circulation. However, the focus of current cell drug delivery systems predominantly lies on live cells, such as red blood cells, white blood cells and others. Here, a drug delivery strategy targeting liver cancer utilizing cryo-shocked liver cancer cells (HepG2) as carriers was presented, and non-proliferative HepG2 cells particles loaded with DOX (HepG2-DOX) was effectively prepared, which has good homologous targeting.
