Molecular mechanism of ischemic postconditioning in promoting diabetic ischemic brain injury repair via the microRNA‐34a–BDNF–SIX3 signaling axis

Animal Models and Experimental Medicine, EarlyView.
Diabetes combined with ischemic stroke (DMIS) exacerbates brain infarct size and neuronal damage compared to nondiabetic ischemic stroke (IS). This study reveals that microRNA‐34a (miR‐34a) plays a key role in DMIS pathogenesis: miR‐34a directly targets and suppresses brain‐derived neurotrophic factor (BDNF) and Sine oculis homeobox 3 (SIX3), promoting

Frontal Recruitment During Response Inhibition in Older Adults Replicated With fMRI [PDF]

, 2003
Recent research has explored age-related differences in multiple areas of cognitive functioning using fMRI, PET, and SPECT. However, because these studies used different tasks, subjects, and methods, little is known about whether the results of these ...

Astrocytic Mitochondria Transplantation Rescues Neuron Loss and Dendritic Injuries in Acute Cerebral Ischemic Stroke Mouse Model by Flexibly Regulating Mitochondria Dynamics

Annals of Neurology, EarlyView.
Objective Cerebral ischemic stroke causes neuronal oxygen/energy deprivation, disrupting mitochondrial function including reduced membrane potential and bioenergetics, exacerbating neuronal injury. Mitochondrial defects are, therefore, a central neuropathological node and potential therapeutic target.

Production of 3D printed biomodels of the canine brain for veterinary neuroanatomy teaching

Anatomical Sciences Education, EarlyView.
Abstract Teaching neuroanatomy presents multiple challenges to both students and teachers, as it is a subject with highly dense content that commonly causes the development of aversion by students, a phenomenon referred to as “neurophobia,” which has been documented in human and veterinary medicine students.

Overcoming intranasal delivery barriers with ultrastable polyzwitterionic siRNA nanocages for enhanced glioblastoma therapy

BMEMat, EarlyView.
A ROS‐responsive, zwitterionic nanocage enables stable, intranasal siRNA delivery to glioblastoma, promoting deep tumor penetration via non‐degradative pathways and trigeminal nerve transport. This platform achieves durable gene silencing and tumor suppression, offering a non‐invasive, storage‐stable strategy for treating glioma and other neurological ...

Perampanel Blocks Transsynaptic α‐Synuclein Propagation and Neurodegeneration in a Mouse Model of Lewy Body Disease

Movement Disorders, EarlyView.
Abstract Background Transsynaptic α‐synuclein propagation plays a crucial role in the progression of Lewy body disease. We previously demonstrated that an α‐amino‐3‐hydroxy‐5‐methyl‐4‐isoxazolepropionic acid receptor antagonist, perampanel, blocks neuronal uptake of α‐synuclein preformed fibrils (PFFs) in an activity‐dependent manner.
