To identified the feasibility and normal range of cone beam computer tomography（CBCT） in the measurement of temporal bone. 15 formalin fixed human cadaver head specimens were scanned by CBCT, high resolution CT, and Micro CT, respectively. Morphological parameter measurements of the middle and inner ear structures including ossicular chain, cochlea, semicircular canal and facial nerve were performed, and the results measured by the three scanning methods were compared. None of the parameters measured by the three scanning methods were statistically significant except the thickness of stapes footplate（<0.01） and the diameter of cochlear basal turn（<0.01）. CBCT was superior in detecting facial nerve bony canal dehiscence. CBCT has the advantages of short scanning time, low radiation dose and high resolution. It can accurately display the morphological characteristics of the temporal bone structures, and is a reliable evaluation method for otological surgery.

The precise manipulation of PANoptosis, a newly defined cell death pathway encompassing pyroptosis, apoptosis, and necroptosis, is highly desired to achieve safer cancer immunotherapy with tumor-specific inflammatory responses and minimal side effects. Nonetheless, this objective remains a formidable challenge. Herein, an "AND" logic-gated strategy for accurately localized PANoptosis activation, utilizing composite 3D-printed bioactive glasses scaffolds integrated with epigenetic regulator-loaded porous piezoelectric SrTiO nanoparticles is proposed.

Background: Few studies investigated the implications of post-PCI QFR and post-PCI ΔQFR (absolute increase of QFR) in de novo lesions of small coronary disease after drug-coated balloon (DCB).
Objectives: We sought to investigate the prognostic implications of post-PCI QFR and post-PCI ΔQFR in patients who received DCB only.
Methods: Patients were divided according to the optimal cutoff value of the post-PCI QFR and the post-PCI ΔQFR.

Lignin is a natural phenolic polymer characterized with renewable, sustainable and biocompatible, but yet remain underutilized. In the post-pandemic era, people are conventionally reusing mask but without any disinfections to prevent infection of virus in public places, which could lead to accumulation of bacteria and secondary infections. The development of antibacterial mask from lignin would simultaneously address the hygiene issues of used mask due to microbe accumulation and provide novel approach for lignin valorization.

Background And Objectives: The use of rapid response EEG (rr-EEG) has recently expanded in limited-resource settings and as a supplement to conventional EEG to rapidly detect and treat nonconvulsive status epilepticus. The study objective was to test the accuracy of an rr-EEG's automated seizure burden estimator (ASBE).
Methods: This is a retrospective observational study using multiple blinded reviewers.

Sinomonas species typically reside in soils or the rhizosphere and can promote plant growth. Sinomonas enrichment in rhizospheric soils is positively correlated with increases in plant biomass. However, the growth promotion mechanisms regulated by Sinomonas remain unclear.
