Multiple optical path length reflections enhancement based on balloon-type photoacoustic cell for trace gas sensing.

A novel balloon-type photoacoustic cell (BTPAC) is proposed to facilitate the detection limitations of acetylene (CH) gas achieving ppb level. Here, an ellipsoidal photoacoustic cavity is employed as the platform for gas-light interaction. By strategically directing the excitation source towards the focal point of the ellipsoidal cavity, ensuring its trajectory traverses the focal point upon each reflection from the interior walls.

Outcomes of fetuses with severe diaphragmatic hernia after fetal endoluminal tracheal occlusion treatment: A series of case reports.

Objective: To explore outcomes of fetuses with severe congenital diaphragmatic hernia (CDH) after fetal endoluminal tracheal occlusion (FETO) treatment.

Case Report: Fetuses diagnosed with severe CDH and taken FETO for intrauterine treatment from January 2020 to December 2023 were recruited. There was no significant difference in general conditions, as well as O/E LHR and measurements related to CDH (p > 0.

Predictors and prognosis of elderly hip fracture patients with perioperative atrial fibrillation: a nested case-control study.

Background: A scarcity of data exists concerning atrial fibrillation (AF) during the perioperative stage of non-cardiothoracic surgery, particularly orthopedic surgery. In addition, given the frequency and significant impact of AF in the perioperative period, therefore our aim was to identify prognosis and predictors of elderly hip fracture patients with perioperative AF.

Methods: An examination of hip fracture patients at the Third Hospital of Hebei Medical University, who had been hospitalized from January 2018 to October 2020 in succession, was conducted retrospectively.

Multi-trait Genome-Wide Analysis Identified 20 Novel Loci for Sarcopenia-Related Traits in UK Biobank.

This study aims to identify novel loci associated with sarcopenia-related traits in UK Biobank (UKB) through multi-trait genome-wide analysis. To identify novel loci associated with sarcopenia, we integrated the genome-wide association studies (GWAS) of usual walking pace (UWP) and hand grip strength (HGS) to conduct a joint association study known as multi-trait analysis of GWAS (MTAG). We performed a transcriptome-wide association study (TWAS) to analyze the results of MTAG in relation to mRNA expression data for genes identified in skeletal muscle.
