Variants and vaccines impact nasal immunity over three waves of SARS-CoV-2.

Viral variant and host vaccination status impact infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), yet how these factors shift cellular responses in the human nasal mucosa remains uncharacterized. We performed single-cell RNA sequencing (scRNA-seq) on nasopharyngeal swabs from vaccinated and unvaccinated adults with acute Delta and Omicron SARS-CoV-2 infections and integrated with data from acute infections with ancestral SARS-CoV-2. Patients with Delta and Omicron exhibited greater similarity in nasal cell composition driven by myeloid, T cell and SARS-CoV-2 cell subsets, which was distinct from that of ancestral cases.

Human Papilloma Virus Infection and Sinonasal Inverted Papilloma Recurrence: A Meta-Analysis.

Objective: Prior studies have been contradictory on the role of human papillomavirus (HPV) infection in sinonasal inverted papilloma (SNIP) recurrence. This systematic review and meta-analysis was performed to further evaluate this potential association.

Data Sources: PubMed, Embase, and Scopus electronic databases.

Investigation of functional characteristics of copper/copper oxide nanoparticles synthesized with Moringa oleifera and Musa sps. extracts: in-vitro and porcine study.

The study analyzed the aqueous leaf extracts of Moringa oleifera and Musa sps. for phytochemical components, including flavonoids, sterols, saponins, tannins, and glycosides. The LC-MS analysis revealed gingerol, vicenin-2, caffeic acid, quercetin, and other compounds in the extracts.

Plant resources for immunonutrients and immunomodulators to combat infectious respiratory viral diseases: a review.

Boosting the immune system has become a crucial aspect in the global battle against the COVID-19 pandemic and other similar infections to protect oneself against symptoms, especially in the prevention of viral infections of the lower respiratory tract. The importance of conducting more studies to create successful herbal formulations as infection prevention measures is emphasized in this review, which looks at the function of immune-boosting nutrients, medicinal plants, and herbal treatments. We reviewed and analyzed 207 studies published from 1946 to the present using reputable databases like Google Scholar, PubMed, and NCBI.
