The Impact of Environmental Pollution and Climate Change on Allergic Rhinitis and Lung Diseases

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Environmental pollution and climate change seriously affect human health, leading to the onset and exacerbation of chronic respiratory diseases, such as allergic rhinitis and lung diseases. Over the past several decades, increasing air pollution and environmental exposure owing to global urbanization, industrialization, and rapid economic ...

Cellular Mechanism and Key Insights in Allergen Immunotherapy for Allergic Rhinitis

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Allergic rhinitis (AR) arises from immune responses mediated by immunoglobulin E (IgE) to inhaled allergens, representing one of the most prevalent chronic conditions worldwide. Although AR may not be a serious ailment, it holds clinical relevance as it underpins numerous complications, serves as a major risk factor for suboptimal asthma ...

Distinct Nasal Microbiome Profiles and Prediction Model for Allergic Rhinitis, Nonallergic Rhinitis, and Healthy Children

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
The alpha and beta diversity of the nasal microbiome differed among children with allergic rhinitis (AR), nonallergic rhinitis (NAR), and healthy controls (HCs). Compared to HC, AR had more Escherichia‐Shigella, Negativicoccus, and Campylobacter, while NAR had more Dolosigranulum and fewer Enterobacteriaceae.

Electron-electron scattering effect on spin relaxation in multi-valley nanostructures

, 2009
We develop a theory of effects of electron-electron collisions on the Dyakonov-Perel' spin relaxation in multi-valley quantum wells. It is shown that the electron-electron scattering rate which governs the spin relaxation is different from that in a ...

Acting on three arenas: A multidimensional approach to understanding ministerial turnover

Scandinavian Political Studies, EarlyView.
Abstract Understanding why cabinet ministers are terminated early is still underexplored. Most existing studies focus on performance on one arena. We argue that ministers operate in many different arenas and to fully understand the complex nature of ministerial termination we need to consider ministers' performance in several arenas and their relation ...

Gate-stack engineering for self-organized Ge-dot/SiO2/SiGe-shell MOS capacitors

Frontiers in Materials, 2016
We report the first-of-its-kind, self-organized gate-stack heterostructure of Ge-dot/SiO2/SiGe-shell on Si fabricated in a single step through the selective oxidation of a SiGe nano-patterned pillar over a Si3N4 buffer layer on a Si substrate.

A new resonant circuit for 2.45 GHz LC VCO with linear frequency tuning [PDF]

, 2011
A new MOS varactor bank is proposed to implement a 2.45 GHz SiGe BiCMOS LC-tank voltage controlled oscillator (VCO) with linear frequency tuning. Compared to a conventional VCO, the proposed technique improves the quality factor of the LC-tank while ...
