Correlation of Preoperative Hippocampal Volume Measured with Magnetic Resonance Imaging and Emergence from General Anaesthesia in Elective Neurosurgical Patients: An Observational Study.

Background And Objectives: The electrophysiological process of emergence from general anesthesia (GA) commences from deeper structures of the brain rather than the cortex. The phylogenetically old parts of the brain (hippocampus) are the first to recover during emergence. Study objectives were to evaluate and predict the effect of preoperative hippocampal volume (HV) measured using MRI with emergence from GA and delayed extubation in patients undergoing elective neurosurgical procedures.

Low expression promotes sensitivity to CHK1 inhibition in high-grade serous ovarian cancer.

High-grade serous ovarian cancer (HGSOC), the most lethal epithelial ovarian cancer subtype, faces persistent challenges despite advances in the therapeutic use of PARP inhibitors. Thus, innovative strategies are urgently needed to improve survival rates for this deadly disease. Checkpoint kinase 1 (CHK1) is pivotal in regulating cell survival during oncogene-induced replication stress (RS).

Thermal imaging through hot emissive windows.

It is not currently possible for an infrared camera to see through a hot window. The window's own blinding thermal emission prevents objects on the other side from being imaged. Here, we demonstrate a path to overcoming this challenge by coating a hot window with an asymmetrically emitting infrared metasurface whose specially engineered imaginary index of refraction produces an asymmetric spatial distribution of absorption losses in its constituent nanoscale resonators.
