Assessing Pulmonary Embolisms on Unenhanced CT Images Using Electron Density Images Derived from Dual-Layer Spectral Detector CT: A Single-centre Prospective Study Conducted at the Emergency Department.

Aims To evaluate the utility of unenhanced spectral imaging, electron density (ED) and overlay electron density (OED) images for assessing pulmonary embolisms in patients with suspected or confirmed acute pulmonary embolism (APE). Background Multiple spectral images can be extrapolated from spectral detector CT (SDCT), ED and OED images. ED and OED images are highly sensitive to moisture-rich tissues.

Enhancing cellulose and hemicellulose degradation in wheat straw composting by inoculation with : key factors and microbial community dynamics.

Actinobacteria are widely used in aerobic composting of straw waste because of their good degradation effect on lignocellulose. However, there are few studies on the degradation effect of on straw. In this study, six laboratory-scale treatments were conducted: corn straw composting with inoculation (CSI), rice straw composting with inoculation (RSI), and wheat straw composting with inoculation (WSI).

Structure and metabolic function of spatiotemporal pit mud microbiome.

Background: Pit mud (PM) hosts diverse microbial communities, which serve as a medium to impart flavor and quality to Baijiu and exhibit long-term tolerance to ethanol and acids, resulting in a unique ecosystem. However, the ecology and metabolic functions of PM remain poorly understood, as many taxa in PM represent largely novel lineages. In this study, we used a combination of metagenomic analysis and chemical derivatization LC-MS analysis to provide a comprehensive overview of microbial community structure, metabolic function, phylogeny, horizontal gene transfer, and the relationship with carboxyl compounds in spatiotemporal PM samples.

Human epididymis protein 4-annexin II binding promotes aberrant epithelial-fibroblast crosstalk in pulmonary fibrosis.

Invasive lung myofibroblasts are the main cause of tissue remodeling in idiopathic pulmonary fibrosis (IPF). A key mechanism contributing to this important feature is aberrant crosstalk between the abnormal/injured lung epithelium and pulmonary fibroblasts. Here, we demonstrate that lungs from patients with IPF and from mice with bleomycin (BLM)-induced pulmonary fibrosis (PF) are characterized by the induction of human epididymis protein 4 (HE4) overexpression in epithelial cells.

KIF9 Ameliorates Neuropathology and Cognitive Dysfunction by Promoting Macroautophagy in a Mouse Model of Alzheimer's Disease.

Alzheimer's disease (AD) is a prevalent neurodegenerative disorder affecting the elderly. The imbalance of protein production and degradation processes leads to the accumulation of misfolded and abnormally aggregated amyloid-beta (Aβ) in the extracellular space and forms senile plaques, which constitute one of the most critical pathological hallmarks of AD. KIF9, a member of the kinesin protein superfamily, mediates the anterograde transport of intracellular cargo along microtubules.
