A fully integrated duplex RT-LAMP device for the detection of viral infections
In this study, we showed and evaluated a prototype of a microfluidic system, and showed that duplex RT-LAMP can detect and distinguish between the two viruses, with LoDs of 2,000 copies/ml for bovine coronavirus and 200 copies/ml for influenza A/X-31 virus.PMID:37682413 | PMC:PMC10491696 | DOI:10.1007/s10544-023-00676-w

Rapid classification of SARS-CoV-2 variant strains using machine learning-based label-free SERS strategy
In this study, the label-free surface-enhanced Raman scattering (SERS) technology combined with machine learning (ML) algorithms provide a potential solution for accurate identification of SARS-CoV-2 variants. We establish a SERS spectral database of SARS-CoV-2 variants and demonstrate that a diagnostic classifier using a logistic regression (LR) algorithm can provide accurate results within 10 min. Our classifier achieves 100% accuracy for Beta (B.1.351/501Y.V2), Delta (B.1.617), Wuhan (COVID-19) and Omicron (BA.1) variants. In addition, our method achieves 100% accuracy in blind tests of positive and negative human nasal...

Stimuli-Responsive Hydrogel Microcapsules Harnessing the COVID-19 Immune Response for Cancer Therapeutics
We present the development of stimuli-responsive microcapsules, loaded with a viral immunogenetic agent, harnessing the immune response against the Coronavirus Disease 2019, COVID-19, to selectively attack liver cancer cells (hepatoma) or recognize breast cancer or hepatoma, by expression of green fluorescence protein, GFP. The pH-responsive microcapsules, modified with DNA-tetrahedra nanostructures, increased hepatoma permeation by 50%. Incorporation of a GFP-encoding lentivirus vector inside the tumor-targeting pH-stimulated miRNA-triggered and Alpha-fetoprotein-dictated microcapsules enables the demonstration of neoplas...

Cycle Threshold Values as Indication of Increasing SARS-CoV-2 New Variants, England, 2020-2022
Emerg Infect Dis. 2023 Sep 7;29(10). doi: 10.3201/eid2910.230030. Online ahead of print.ABSTRACTEarly detection of increased infections or new variants of SARS-CoV-2 is critical for public health response. To determine whether cycle threshold (Ct) data from PCR tests for SARS-CoV-2 could serve as an early indicator of epidemic growth, we analyzed daily mean Ct values in England, UK, by gene target and used iterative sequential regression to detect break points in mean Ct values (and positive test counts). To monitor the epidemic in England, we continued those analyses in real time. During September 2020-January 2022, a tot...

First cases of SARS-CoV-2 BA.2.86 in Denmark, 2023
We describe 10 cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant BA.2.86 detected in Denmark, including molecular characteristics and results from wastewater surveillance that indicate that the variant is circulating in the country at a low level. This new variant with many spike gene mutations was classified as a variant under monitoring by the World Health Organization on 17 August 2023. Further global monitoring of COVID-19, BA.2.86 and other SARS-CoV-2 variants is highly warranted.PMID:37676147 | DOI:10.2807/1560-7917.ES.2023.28.36.2300460

A standardised protocol for relative SARS-CoV-2 variant severity assessment, applied to Omicron BA.1 and Delta in six European countries, October 2021 to February 2022
In conclusion, this study demonstrates the feasibility of conducting variant severity analyses in a multinational collaborative framework and adds evidence for the reduced severity of the Omicron BA.1 variant.PMID:37676146 | DOI:10.2807/1560-7917.ES.2023.28.36.2300048

COVID-19: An Overview of SARS-CoV-2 Variants-The Current Vaccines and Drug Development
Biomed Res Int. 2023 Aug 29;2023:1879554. doi: 10.1155/2023/1879554. eCollection 2023.ABSTRACTThe world is presently in crisis facing an outbreak of a health-threatening microorganism known as COVID-19, responsible for causing uncommon viral pneumonia in humans. The virus was first reported in Wuhan, China, in early December 2019, and it quickly became a global concern due to the pandemic. Challenges in this regard have been compounded by the emergence of several variants such as B.1.1.7, B.1.351, P1, and B.1.617, which show an increase in transmission power and resistance to therapies and vaccines. Ongoing researches are ...

Elevated tacrolimus levels among COVID-19 kidney transplant recipients are associated with worse disease severity and clinical outcomes
CONCLUSION: Elevated tacrolimus levels occur in many renal transplant recipients with moderate to severe COVID-19 and are associated with worse clinical outcomes. Close drug monitoring is crucial to avoid toxicities and minimize over-immunosuppression complications.PMID:37675489 | DOI:10.5414/CN111137
