Subarachnoid hemorrhage (SAH) is a devastating cerebrovascular event associated with high mortality and significant morbidity. Recent studies have highlighted the emerging role of ferroptosis, a novel form of regulated cell death, in the pathogenesis of SAH. Circular RNAs (circRNAs), have been found to play essential roles in various cellular processes, including gene regulation and disease pathogenesis.

The most effective approaches to treating ALI include disrupting inflammatory cascades and associated inflammatory damage within the lung. Hederagenin was utilized as a core skeleton to design and synthesize 33 hederagonic acid derivatives.

In this work, we apply a virtual-focus scanning method to detect a tumor inside a simplified two-dimensional breast model via the finite difference time domain method. For the purpose of simplification, we construct a microwave detection system with an N-element infinitesimal dipole array, and excite the central element of the array while letting all elements receive the time-shifted scattered fields in order to filter out unwanted signals. With the application of the two-step, virtual-focus scanning method, our computerized prototype system has accurately detected randomly generated tumors in all cases investigated, including small tumors in early stages of development.
