Quantitative Susceptibility Mapping (QSM) is a technique that derives tissue magnetic susceptibility distributions from phase measurements obtained through Magnetic Resonance (MR) imaging. This involves solving an ill-posed dipole inversion problem, however, and thus time-consuming and cumbersome data acquisition from several distinct head orientations becomes necessary to obtain an accurate solution. Most recent (supervised) deep learning methods for single-phase QSM require training data obtained via multiple orientations.

The development of the mammalian neocortex is precisely regulated by temporal gene expression, yet the temporal regulatory mechanisms of cortical neurogenesis, particularly how radial glial cells (RGCs) sequentially generate deep to superficial neurons, remain unclear. Here, the hnRNP family member Syncrip (hnRNP Q) is identified as a key modulator of superficial neuronal differentiation in neocortical neurogenesis. Syncrip knockout in RGCs disrupts differentiation and abnormal neuronal localization, ultimately resulting in superficial cortical layer defects as well as learning and memory impairments in mice.

Background: Bilateral deep brain stimulation (DBS) of subthalamic nucleus (STN) has demonstrated efficacy for ameliorating medication-refractory isolated dystonia. Nonetheless, the paucity of evidence regarding its long-term impact on quality-of-life (QoL) necessitates further investigation.
Objectives: This study aimed to elucidate the longitudinal effects of chronic STN stimulation on QoL in patients suffering from isolated dystonia.

Effective delivery of therapeutic agents for solid tumour treatment is impeded by multiple obstacles, such as aberrant interstitial fluid pressure and high density of the extracellular matrix, which causes impaired penetration to deep avascular tumour tissue that exists in a hypoxic immune cold environment. Only limited tumoricidal effects have been achieved with traditional nanomedicine due to its inefficient penetration and the multiple resistant effects that exist in the tumour microenvironment. Herein, a new chemo-dynamic immunotherapy (CDIT) is proposed based on a transcytosis tumour oxygenator (MnP) with effective chemo-dynamic effects.

Neuromorphic engineering has emerged as a promising avenue for developing brain-inspired computational systems. However, conventional electronic AI-based processors often encounter challenges related to processing speed and thermal dissipation. As an alternative, optical implementations of such processors have been proposed, capitalizing on the intrinsic information-processing capabilities of light.
