ABSTRACT Background Chronic rhinosinusitis is common in people with cystic fibrosis (PwCF). Highly effective modulator therapy (HEMT) has been shown to improve sinonasal outcomes. However, prior studies failed to show improvement in objective olfaction with HEMT, and the impact of HEMT on olfactory‐specific quality of life has yet to be studied ...

ABSTRACT Objective This study investigated the developmental differences in structure, gene expression, and function of human olfactory epithelium (OE) using pediatric and adult specimens and human olfactory organoids. Background Olfactory dysfunction (OD) is characterized by loss or alterations in the sense of smell and has an age‐related increase in ...

Mechanistische Diversität in der photoangeregten Radikal‐Redoxchemie: Eine kritische Evaluierung
Für viele prominente Beispiele der Photoredox‐Katalyse wird angenommen, dass sie über die Anregung einer offenschaligen („open‐shell“) Zwischenform des Katalysators ablaufen. Es wird jedoch intensiv darüber diskutiert, ob solche Mechanismen realistisch sind und, falls ja, wie genau sie ablaufen können.

Mechanistic Diversity in Photoexcited Radical Redox Chemistry: A Critical Evaluation
Many high‐profile examples of photoredox catalysis are proposed to proceed via excitation of an open‐shell intermediate form of the catalyst. However, there is much debate over whether such mechanisms are realistic and, if so, exactly how they can occur.

Rapid assessment of fern spore quality using microscale electrical conductivity testing
Abstract Premise Ex situ spore banks are essential for fern conservation and research, yet traditional germination tests for assessing spore quality are time consuming and labor intensive. We explored whether electrical conductivity (EC), a rapid proxy for seed vigor, could offer an efficient alternative for evaluating fern spore quality. Methods Using

Steganalysis techniques have been classified into two major categories: blind steganalysis which is independent of the steganography method and specific steganalysis which attempts to detect specific steganographic media.

Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Complement Activation Linked to Type II Interferon Signaling in Still Disease
Objective Still disease (SD) is an autoinflammatory syndrome characterized by innate immune dysregulation. Although complement can drive inflammation, its involvement in SD remains to be defined. Thus, we aimed to assess complement activation in SD. Methods Complement was assessed using transcriptomic, proteomic, and in vitro approaches. RNA sequencing
