Ferroptosis-related alternative splicing signatures as potential biomarkers for predicting prognosis and therapy response in gastric cancer.

Ferroptosis is linked to various tumor biological traits, and alternative splicing (AS), a crucial step in mRNA processing, plays a role in the post-transcriptional regulation of ferroptosis-related genes (FRGs). A least absolute shrinkage and selection operator (LASSO) penalized Cox regression analysis was utilized to build a prognostic signature based on 12 AS events (p < 0.05), which was validated in gastric cancer (GC) patients.

Out-of-focus signal rejection for pO measurements using two-photon phosphorescence lifetime microscopy.

Two-photon phosphorescence lifetime microscopy has been a key tool for studying cerebral oxygenation in mice. However, the accuracy of the partial pressure of oxygen (pO) measurements is affected by out-of-focus signal. In this work, we applied reconfigurable differential aberration imaging to characterize and correct for out-of-focus signal contamination in intravascular pO imaging.

Design and development of pyrazol-5-ylbenzamide derivatives containing chiral oxazoline moiety as fungicides based on molecular docking.

Background: Development of novel chiral antifungal agents for effective control of plant pathogens is urgently needed. In this study, a series of pyrazol-5-yl-benzamide derivatives containing chiral oxazoline moiety were rationally designed and developed based on molecular docking.

Results: The in vitro antifungal assay results indicated that compounds (rac)-4h (R = Et), (S)-4 h (R = S-Et) and (R)-4 h (R = R-Et) exhibited remarkable antifungal activities against Valsa mali with median effective concentration (EC) values of 0.

Mechanisms to improve measurement accuracy through differential signaling in homodyne interferometers.

Homodyne interferometers (HIs) utilize differential signaling to reduce common-mode noise and enhance measurement stability. However, their potential to improve measurement accuracy has not been thoroughly investigated. To address this gap, we reveal two unrecognized mechanisms enabled by differential-output signal (DS): self-compensation for odd-order periodic nonlinear error (PNE) and mitigation of PNE caused by ghost reflections.

Prediction and unsupervised clustering of fertility intention among migrant workers based on machine learning: a cross-sectional survey from Henan, China.

Background: Although China has implemented multiple policies to encourage childbirth, the results have been underwhelming. Migrant workers account for a considerable proportion of China's population, most of whom are of childbearing age. However, few articles focus on their fertility intentions.
