Mechanisms and challenges of nanocarriers as non-viral vectors of therapeutic genes for enhanced pulmonary delivery
J Control Release. 2022 Nov 10:S0168-3659(22)00739-8. doi: 10.1016/j.jconrel.2022.10.061. Online ahead of print.ABSTRACTWith the rapid development of biopharmaceuticals and the outbreak of COVID-19, the world has ushered in a frenzy to develop gene therapy. Therefore, therapeutic genes have received enormous attention. However, due to the extreme instability and low intracellular gene expression of naked genes, specific vectors are required. Viral vectors are widely used attributed to their high transfection efficiency. However, due to the safety concerns of viral vectors, nanotechnology-based non-viral vectors have attrac...

Abstracts of Presentations at the Association of Clinical Scientists 143 < sup > rd < /sup > Meeting Louisville, KY May 11-14,2022
Conclusion: These assays are suitable for routine diagnostic. The UltraFast NextGenPCR is the fastest with average time (30mins), followed by Agilent (2 hrs) and MassArray (6hrs). Upon completion of this activity, participants should be able to examine, measure and compare results from different assays for SARS detection, evaluate and diagnose accurately, as well as being able to plan, organize and recommend a diagnostic procedure for diagnostic laboratory. Key words: SARS-CoV-2, RNA extraction, RT-PCR, limit of detection, quantification cycle, COVID-19, in vitro diagnostic tests, Agilent, Massarray, Ultrafast. [20] From t...

Potential inhibitors and plant based technology: An alternative approach to treat corona virus
Bioorg Chem. 2021 Nov 1;117:105460. doi: 10.1016/j.bioorg.2021.105460. Online ahead of print.ABSTRACTThe current pneumonia outbreak, which began in early December 2019 near Wuhan City, Hubei Province, China, is caused by a novel corona virus (CoV) known as '2019-nCoV' or '2019 novel corona virus or COVID-19' by the World Health Organization (WHO). Vaccines are available to prevent corona virus contagious infection or to reduce the viral load in body but virus is continuously mutating itself to infect people at severity. In this critical scenario this review provide a compiled study for techniques and tools that can be used...

Immune-Modulation by the Human Respiratory Syncytial Virus: Focus on Dendritic Cells
This study is complemented by another report that found that hRSV infection induces significant expression of three miRNAs, namely hsa-miR-4448, hsa-miR-30a-5p, and hsa-miR-4634 in human DCs (104). Interestingly, this latter study also performed comparative analyses of miRNA profiles between DCs infected with hRSV and a related virus, namely the human metapneumovirus, and found that both viruses induced the expression of elevated levels of hsa-miR-4634. Elucidating the contribution of these miRNAs in DCs in response to hRSV remains to be determined. Dendritic Cell Phenotype and Migration Upon hRSV Infection in vivo Altho...
