A new dicyanophenanthrene-based thermally activated delayed fluorophore: Design, synthesis, photophysical study, and electroluminescence application.

A novel thermally activated delayed fluorescence (TADF) emitter, DCNP-SCF, is developed based on a dicyanophenanthrene acceptor. DCNP-SCF is prepared by a simple C-N coupling reaction. Its thermal, theoretical, photophysical, and electroluminescent properties are investigated, emphasizing its potential in organic electroluminescence devices.

Effects of Intranasal Cellulose Powder on Asthma Control in Children With Mild-to-Moderate Perennial Allergic Rhinitis: A Randomized, Placebo-Controlled Trial.

Background: Perennial allergic rhinitis (PAR) often coexists in asthmatic patients. Intranasal cellulose powder (ICP) was reportedly effective in ameliorating PAR.

Objective: We investigated whether ICP is equally effective compared with intranasal corticosteroids in improving asthma control as well as nasal symptoms among children with PAR and allergic asthma (AA).

Food allergy and related risk factors in 2540 preschool children: an epidemiological survey in Guangdong Province, southern China.

Background: Although the number of studies on allergic diseases in the general population of southern China is increasing, only a few have addressed food allergy (FA) in children in this region. The present study aimed to investigate the prevalence, clinical manifestations, spectrum of allergens, and related risk factors of FA in preschool children in Guangdong Province, southern China.

Methods: A random cluster-sampling method was used to select 24 kindergartens from 12 cities in Guangdong Province.

Allergy-related evidences in relation to serum IgE: data from the China state key laboratory of respiratory disease, 2008-2013.

Objective: To investigate the serum total IgE (tIgE) and specific IgE (sIgE) to common allergens among allergic patients in Guangzhou, China.

Methods: 7 085 patients were examined for tIgE and sIgE to 15 allergens, based on the protocols of reversed enzyme allergosorbent test and the sandwich enzyme-linked immunosorbent assay.

Results: 3 758 (53.

Prevalence of allergen sensitization among patients with allergic diseases in Guangzhou, Southern China: a four-year observational study.

Background: The distribution of allergens may vary with different geographic areas, suggesting the importance of local epidemiological data to support evidence-based prevention and management of allergic diseases. We investigated the distribution of common allergens in allergic patients in Guangzhou, southern China.

Methods: 7,047 patients with allergic symptoms were examined for serum sIgE to 15 common allergens in this region, based on the protocol of reversed enzyme allergosorbent test.
