Background: New hydrofluoroalkane (HFA) formulations of glucocorticoids have been shown to effectively control asthma. HFA glucocorticoids are deposited across all sizes of airways, including the small ones. However, it is not clear whether they can suppress peripheral airway inflammation.
Objective: We sought to determine whether HFA-flunisolide could suppress peripheral inflammation in asthma.
Methods: Twelve patients with mild to moderate asthma received HFA-flunisolide for 6 weeks. Transbronchial and endobronchial biopsy specimens were obtained before and after treatment, and spirometry was performed. Changes in inflammatory cells (eosinophils, neutrophils, lymphocytes, macrophages, basophils) and IL-5 and eotaxin were measured by using immunocytochemistry and in situ hybridization.
Results: Lung function significantly improved after treatment (P <.05). HFA-flunisolide significantly reduced eosinophils, IL-5, and eotaxin in both peripheral and central airways (P <.01). Neutrophils significantly increased after treatment in peripheral and central airways (P <.05). The numbers of lymphocytes remained unchanged.
Conclusions: These results show that HFA-flunisolide effectively suppressed eosinophilic inflammation in peripheral and central airways. These changes were accompanied by improvement in lung function.

Methods: In vivo confocal microscope images at the corneal central and mid-peripheral subbasal level were evaluated in 18 OK wearers, 18 SCL wearers and 18 non-wearers (mean age 27.

In general, ghrelin is known as one of the orexigenic hormones in mammals. On the other hand, it has been shown that ghrelin inhibits water intake, which appear to be inconsistent with its role in the feeding response. In this study, the effect of ghrelin on water intake was comprehensively addressed using conscious seawater-acclimated eels known as an experimental model for water drinking behaviour.

Developing highly efficient deep-blue multi-resonance thermal activated delayed fluorescence (MR-TADF) materials for ultra-high-definition organic light-emitting diodes (OLEDs) displays that meet the stringent BT.2020 standard remains a significant challenge. In this study, we present a strategy to achieve high-performance deep-blue MR-TADF emitters by integrating a large π-conjugated double-boron-embedded MR skeleton with strategically positioned peripheral steric hindrance groups.

Background: Dishevelled-associated activator of morphogenesis1 (DAAM1) is a member of the evolutionarily conserved Formin family and plays a significant role in the malignant progression of various human cancers. This study aims to explore the clinical and biological significance of DAAM1 in pancreatic cancer.
Methods: Multiple public datasets and an in-house cohort were utilized to assess the clinical relevance of DAAM1 in pancreatic cancer.
