Type 2 biomarkers in olfactory cleft mucus correlate with SNOT-22 in chronic rhinosinusitis independent of nasal polyp status.

Background: Quantitative mucus cytokine analysis to examine the sinonasal microenvironment may bridge the gap between patient-reported outcome measures (PROMs) and empirical measures of inflammation in patients with chronic rhinosinusitis (CRS).

Objective: Investigate the correlation between mucus cytokine levels and Sino-Nasal Outcome Test (SNOT-22) scores, including individual subdomains.

Methods: Patients with CRS were prospectively recruited between 2016 and 2021 into a multi-institutional observational study.

Privately negotiated facility fees at ambulatory surgery centers and hospitals.

Private negotiated facility fees at hospitals are on average double the ambulatory surgery center facility fees for common outpatient procedures.

A novel polyurethane-based silver foam dressing with superior antimicrobial action for management of infected chronic wounds.

Wound healing is a complex and dynamic process supported by several cellular events. Around 13 million individuals globally suffer from chronic wounds yearly, for which dressings with excellent antimicrobial activity and cell viability (>70%, as per ISO 10993) are needed. Excessive use of silver can cause cytotoxicity and has been linked to increasing antimicrobial resistance.

Comparative analysis of the antimicrobial activity and dye degradation of metal oxides (TiO, CdO, MnO, and ZnO) nanoparticles using a green approach.

A tremendous amount of recent work has been done on different metal oxide nanomaterials for biological activities and photocatalytic dye degradation. This work used the Cissus quadrangularis leaf extract to prepare TiO, CdO, MnO, and ZnO nanoparticles using a green synthesis approach. To ascertain the physicochemical characteristics of the generated metal oxide nanoparticles, various characterisation techniques were used.
