Introduction: The extent to which sinks are contaminated by carbapenem-resistant (CRAB) in intensive care units (ICUs) and the association between these contaminated sinks and hospital-acquired CRAB infections during the non-cluster period remains largely unknown. Here, we performed a prospective multicenter study in 16 ICUs at 11 tertiary hospitals in Chengdu, China.
Methods: We sampled sinks, collected CRAB clinical isolates, and conducted whole-genome sequencing and analysis.
Pterostilbene (PST), a 3',5'-O-methylated derivative of resveratrol (RSV), is a potent natural antioxidant produced by some plants in trace amounts as defense compound. It exhibits various health-promoting activities, such as anticancer, antiviral, and antimicrobial effects. Large-scale biosynthesis of PST is crucial due to the challenges associated with extracting it from plants.

We aimed to investigate whether first-line concurrent thoracic radiotherapy (TRT) and EGFR-tyrosine kinase inhibitors (TKIs), compared with TKIs alone, could achieve better survival.
Materials And Methods: The patients in the TKI plus TRT group received 60 Gy to primary lung tumor and positive regional lymph nodes.

Summary: With the development of high-throughput sequencing, various biological roles of tsRNAs have been gradually revealed, including regulation of mRNA stability, transcription, translation, direct interaction with proteins and as epigenetic factors, etc. Recent studies have shown that tsRNAs are also closely related to renal disease.
We have developed a rapid detection instrument to characterize the behavior of light on the surface of devices during light-matter interactions. The equipment enables the non-destructive and real-time observations of the dispersion curves for microstructures, providing the basis for a large number of new planar photonic chip applications. The method is based on the traditional prismatic reflection and makes full use of the grating dispersion capabilities, enabling simultaneous multi-wavelength and multi-angle reflectance measurements over a wide range.

NARFL knockout dramatically impaired mitochondrial integrity in mice, which might promote mitochondrial dysfunction and lead to worse survival rate of lung cancer. However, the underlying molecular mechanism of NARFL deficiency in non-small cell lung cancer (NSCLC) is unknown.

However, it is unclear which image features of lung involvement can predict the therapeutic response in MPO-AAV patients, which is vital in decision-making for these patients. Our aim was to develop and validate a radiomics nomogram to predict treatment resistance of Chinese MPO-AAV patients based on low-dose multiple slices computed tomography (MSCT) of the involved lung with cohorts from two centers.

We have previously reported that Vitamin D receptor (VDR) exert renoprotection in rodent AKI models. However, whether ATF4, as well as ERS, is involved in the protective effect of VDR in ischemia-reperfusion (I/R) induced AKI is unknown.

Up to now, the underlying pathogenesis of ischemic AKI remains incompletely understood, and specific strategies for early diagnosis and treatment of ischemic AKI are still lacking. Here, this study aimed to define the transcriptomic landscape of AKI patients through single-cell RNA sequencing (scRNA-seq) analysis in kidneys.

Here, we found plasma fluorescence spectra can rapidly assess the severity of mesenteric ischemia injury in animal models. Ischemia-reperfusion damage of the intestine leads to multiple times increase in NADH, flavins, and porphyrin auto-fluorescence of blood.

The present study aims to investigate the role of GPX3 as well as its correlation with vitamin D-vitamin D receptor (VD-VDR) in ischemia-reperfusion (I/R)-induced renal oxidative stress injury. We showed that the expression of GPX3 and VDR were consistently decreased in renal tissues of I/R-related AKI patients and mice models.
