Article Synopsis
- Widespread testing for COVID-19 is hampered by a global shortage of essential supplies like RNA extraction kits, which are crucial for detecting the virus's genetic material.
- The proposed PEARL method (precipitation-enhanced analyte retrieval) overcomes this issue by using a simple lysis solution that disrupts cells and enables efficient RNA, DNA, and protein extraction.
- PEARL is a fast, cost-effective alternative that relies on common lab reagents, providing performance comparable to commercial kits and streamlining the detection of viruses like SARS-CoV-2.

Article Abstract
Management of the coronavirus disease 2019 (COVID-19) pandemic requires widespread testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A main limitation for widespread SARS-CoV-2 testing is the global shortage of essential supplies, among them RNA extraction kits. The need for commercial RNA extraction kits places a bottleneck on tests that detect SARS-CoV-2 genetic material, including PCR-based reference tests. Here, we propose an alternative method we call PEARL (recipitation-nhanced nalyte etrieva) that addresses this limitation. PEARL uses a lysis solution that disrupts cell membranes and viral envelopes while simultaneously providing conditions suitable for alcohol-based precipitation of RNA, DNA, and proteins. PEARL is a fast, low-cost, and simple method that uses common laboratory reagents and offers performance comparable to that of commercial RNA extraction kits. PEARL offers an alternative method to isolate host and pathogen nucleic acids and proteins to streamline the detection of DNA and RNA viruses, including SARS-CoV-2.

Division of Gastroenterology, Acireale Hospital, Azienda Sanitaria Provinciale di Catania, Catania, Italy.
Background And Aims: Gut-liver axis has been implicated in the pathophysiology of cirrhosis due to metabolic dysfunction-associated steatotic liver disease (MASLD), an in vitro model for studying epithelial gut dysfunction in MASLD is lacking. In this study, we aimed to characterise intestinal organoids derived from subjects with MASLD.
Materials And Methods: Intestinal organoids were obtained from duodenal samples of individuals with non-fibrotic MASLD and with MASLD-cirrhosis.

Low-cost and high-throughput RNA sequencing data for barley RILs achieved GP performance comparable to or better than traditional SNP array datasets when combined with parental whole-genome sequencing SNP data. The field of genomic selection (GS) is advancing rapidly on many fronts including the utilization of multi-omics datasets with the goal of increasing prediction ability and becoming an integral part of an increasing number of breeding programs ensuring future food security. In this study, we used RNA sequencing (RNA-Seq) data to perform genomic prediction (GP) on three related barley RIL populations.

The zoonotic infectious disease, severe fever with thrombocytopenia syndrome (SFTS), caused by the SFTS virus (SFTSV), , was first identified in China in 2009 and reported in the Republic of Korea in 2013. The primary vector is the tick (.) , which is endemic to the Asia-Pacific region and has a wide range of hosts.

Background: The dysregulation of long-chain noncoding RNAs (lncRNAs) causes several complex human diseases including neurodegenerative disorders across the globe.
Methods And Results: This study aimed to investigate lncRNA expression profiles of Withania somnifera (WS)-treated human neuroblastoma SK-N-SH cells at different timepoints (3 & 9 h) and concentrations (50 & 100 µg/mL) using RNA sequencing. Differential gene expression analysis showed a total of 4772 differentially expressed lncRNAs, out of which 3971 were upregulated and 801 were downregulated compared to controls.

Unlabelled: There is a need for the development of broad-spectrum antiviral compounds that can act as first-line therapeutic countermeasures to emerging viral infections. Host-directed approaches present a promising avenue of development and carry the benefit of mitigating risks of viral escape mutants. We have previously found the SKI (super killer) complex to be a broad-spectrum, host-target with our lead compound ("UMB18") showing activity against influenza A virus, coronaviruses, and filoviruses.
