Background: Several major sensitization profiles have been described in children with asthma, but it remains unclear how these profiles relate to asthma phenotypes. The aim of this study was to determine allergenic sensitization profiles in a megacity cohort (SAMP).

Methods: This was a cross-sectional analysis performed from 2011 to 2015 including preschool and school-age children with severe and moderate asthma from the SAMP cohort.

Background: Chronic non-cancer pain (CNCP) is a common condition worldwide. The disease burden is influenced not only by pain itself, but also by psychiatric co-morbidities, which aggravate symptoms, generally negatively influence therapies, and may thereby lead to frustration, resignation, or withdrawal. A growing body of evidence suggests that sex and gender aspects influence CNCP management as the experience of pain, the emotions associated with it, and the expression of pain may differ between women and men.

We have used grazing incidence X-ray absorption near edge spectroscopy (XANES) to investigate the behavior of monolayer FeO films on Pt(111) under near ambient pressure CO oxidation conditions with a total gas pressure of 1 bar. Spectra indicate reversible changes during oxidation and reduction by O and CO at 150 °C, attributed to a transformation between FeO bilayer and FeO trilayer phases. The trilayer phase is also reduced upon heating in CO+O , consistent with a Mars-van-Krevelen type mechanism for CO oxidation.

Article Synopsis
  • Understanding the relationship between the structure and properties of electrocatalysts is essential for designing better materials, and the Aarhus University reactor for electrochemical studies using X-rays (AUREX) provides a versatile and user-friendly setup for this research.
  • The AUREX cell allows for various advanced measurement techniques like total scattering, diffraction, and absorption spectroscopy on commercial silver electrocatalysts, enabling real-time observation of structural changes during electrochemical reactions.
  • The findings reveal that silver transitions from a face-centered cubic structure to other phases under oxidative conditions, and the setup is crucial for studying these phase transitions, highlighting the need for careful beam settings to avoid interference during experiments.

Article Synopsis
  • The 46,XX testicular disorder/difference of sex development (DSD) is a rare condition where individuals typically have female chromosomes (46,XX) but display male characteristics, often due to the translocation of a Y chromosome segment to the X chromosome.
  • Researchers conducted extensive genetic analysis on blood samples from individuals with 46,XX DSD and controls to explore the genetic variations and their effects on phenotype.
  • The study revealed distinct categories of translocated Y chromosome segments and identified transcriptional changes linked to phenotypic traits like height and testicular size, enhancing the understanding of the genetic factors involved in 46,XX DSD.
