Adaptive deep brain stimulation (DBS) provides individualized therapy for people with Parkinson's disease (PWP) by adjusting the stimulation in real-time using neural signals that reflect their motor state. Current algorithms, however, utilize condensed and manually selected neural features which may result in a less robust and biased therapy. In this study, we propose Neural-to-Gait Neural network (N2GNet), a novel deep learning-based regression model capable of tracking real-time gait performance from subthalamic nucleus local field potentials (STN LFPs).

Department of Neurosurgery, Division of Functional and Integrative Medicine, Department of Neurosurgery, Akita University Graduate School of Medicine, 1-1-1 Hondo, Akita 010-8543, Japan.

Laser speckle flowmetry (LSF) is a noninvasive tool for cerebral blood flow (CBF) measurement via a cranial bone window. LSF is influenced by various factors including the extent of removal of bone and dura mater and tissue wetness in the bone window. In this study, we aimed to characterize the effect of these conditions on LSF signals and identify optimal measurement conditions for CBF LSF measurements in rats.

Electronic address:

Unlabelled: Carotid Blowout Syndrome (CBS) is a rare and life-threatening condition that necessitates prompt intervention to prevent fatal hemorrhage. This study compares the outcomes of two primary endovascular approaches: reconstructive interventions, which aim to preserve carotid artery function using stents or balloon angioplasty, and deconstructive interventions, which involve vessel occlusion to halt bleeding. A systematic review and meta-analysis were performed by searching multiple databases for relevant studies published from January 2000 to August 2023.

Department of Radiation Medicine, Roswell Park Comprehensive Cancer Center, Buffalo, NY, USA; Department of Neurosurgery, Roswell Park Comprehensive Cancer Center, Buffalo, NY 14203, USA. Electronic address:

Background: Glioblastoma (GBM) is a common brain tumor with a poor prognosis. There is a paucity of knowledge regarding optimal treatment approaches for elderly patients with GBM who have a relatively good Karnofsky (KPS) or Eastern Cooperative Oncology Group (ECOG) performance status. This study compared treatment outcomes in older patients (≥65) with GBM based on their performance status, either high (KPS ≥ 70 and ECOG < 2) or low (KPS < 70 and ECOG ≥ 2), who underwent hypofractionated radiotherapy (HFRT) (40 Gy in 15 fractions) versus conventional fractionation (60 Gy in 30 fractions).

Department of Biomedical Engineering, Whiting School of Engineering, The Johns Hopkins University, Baltimore, MD, USA; Translational Tissue Engineering Center, Whiting School of Engineering, Johns Hopkins School of Medicine, Baltimore, MD, USA. Electronic address:

This study defines biochemical mechanisms that contribute to novel neural-regenerative activities we recently demonstrated for thiol-modified ManNAc analogs in human neural stem cells (hNSCs) by comparing our lead drug candidate for brain repair, "TProp," to a "size-matched" N-alkyl control analog, "But." These analogs biosynthetically install non-natural sialic acids into cell surface glycans, altering cell surface receptor activity and adhesive properties of cells. In this study, TProp modulated sialic acid-related biology in hNSCs to promote neuronal differentiation through modulation of cell adhesion molecules (integrins α6, β1, E-cadherin, and PSGL-1) and stem cell markers.

The position and configuration of the C═C bond have a significant impact on the spatial conformation of unsaturated lipids, which subsequently affects their biological functions. Double bond isomerization of lipids is an important mechanism of bacterial stress response, but its in-depth mechanistic study still lacks effective analytical tools. Here, we developed a visible-light-activated dual-pathway reaction system that enables simultaneous [2 + 2] cycloaddition and catalytic - isomerization of the C═C bond of unsaturated lipids via directly excited anthraquinone radicals.

Background: There are limited therapeutic options in cases of failed reperfusion (modified thrombolysis in cerebral infarction [mTICI] score < 2b) after stent-retriever and/or aspiration based endovascular treatment (EVT) for acute ischemic stroke. Despite the absence of data supporting its use, rescue therapy (balloon angioplasty and/or stent implantation) is often utilized in such cases. Studies are limited to large vessel occlusions, while the outcomes and complications after rescue therapy in medium/distal vessel occlusions (MDVOs) have not been reported.

Intra-arterial Alteplase Thrombolysis After Successful Thrombectomy for Acute Ischemic Stroke in the Posterior Circulation (IAT-TOP): Study Protocol and Rationale.

Int J Stroke

January 2025

Department of Neurosurgery and Interventional Neuroradiology, Xuanwu Hospital, China International Neuroscience Institute, Capital Medical University, National Center for Neurological Disorders, 45 Changchun St, Beijing 100053, China.

Rationale: The Chemical Optimization of Cerebral Embolectomy (CHOICE) trial suggested that the administration of intra-arterial alteplase after successful endovascular thrombectomy (EVT) may improve neurological outcomes in patients with acute ischemic stroke due to large vessel occlusion (AIS-LVO) in the anterior circulation. However, the use of adjunctive intra-arterial alteplase following successful EVT in acute posterior circulation stroke remains unexplored.

Aims: This study aims to investigate the efficacy and safety of intra-arterial alteplase after successful EVT for AIS-LVO in the posterior circulation.

Nowadays, consent to use donor bodies for medical education and research is obtained from the body donors and their families before the donation. Recently, the International Federation of Associations of Anatomists (IFAA) published guidelines that could restrict the appearance of cadaveric images in commercial anatomical resources such as textbooks and other educational products. These guidelines state that the donor must expressly consent to using such images for this purpose.
