A study by the Istituto Neurologico Mediterraneo Neuromed I.R.C.C.S. found that consuming ultra-processed foods significantly increases the risk of a second heart attack or fatal stroke in people with cardiovascular diseases, even if they follow the Mediterranean diet.
Researchers at GIST create an optical technique called optical speckle image velocimetry that can image dynamic changes in cerebral blood flow, allowing for the diagnosis of brain health. The technique provides high-time resolution and measures both speed and direction of blood flow.
A first-in-human study at Cleveland Clinic found that targeting the dentate nucleus with deep brain stimulation was safe and feasible for promoting post-stroke rehabilitation, enabling significant functional improvement in upper extremity hemiparesis. The study's adaptive design allowed for extended treatment duration if patients conti...
Researchers from the University of Tsukuba found that blocking CD300a enhances efferocytosis and ameliorates neuronal deficits after ischemic stroke. This process involves the removal of damaged cells in the brain, reducing inflammation and neurological impairment.
The CAPTIVA trial will enroll 1,683 patients with symptomatic intracranial arterial stenosis and determine if two new prospective therapies are more effective than aspirin plus clopidogrel at reducing the risk of a second stroke. Intensive medical management and lifestyle modifications will also be provided to all patients.
Researchers found that 18:1 LPE promotes neurite outgrowth and protects neurons from glutamate toxicity, suggesting a key role for LPE in brain function. The study provides new insights into the physiological importance of LPE and its potential as a therapeutic agent for cranial nerve damage.
Researchers have developed a hybrid device that uses near-infrared light to monitor blood flow, providing a quick and noninvasive diagnosis of cerebral ischemia. The device can record comprehensive profiles of hemodynamics, improving treatment effectiveness within the first few hours of stroke onset.
Researchers found that hypothermia can limit cell death and dynamin levels in mice with cerebral blockage. This suggests that dynamin may be a potential drug target for stroke-related neuronal cell death.
Research suggests that autophagy may be both beneficial and detrimental to neuronal survival after stroke. The study proposes that autophagy has dual effects on neuronal survival, highlighting the need for further investigation into its therapeutic potential.
Research by Dr. Hyung-Seok Kim reveals that early expressions of hypoxia-inducible factor 1 alpha and vascular endothelial growth factor increase the neuronal plasticity of activated endogenous NSCs after focal cerebral ischemia. Additionally, neural precursor cells can be recruited from nearby areas to promote neurofunctional recovery.
Researchers studied rat and mouse models of focal cerebral ischemia to develop high-quality rodent models of stroke. They found optimal methods for middle cerebral artery occlusion in rats (0.40-0.45 mm, 18-20 mm thread insertion length) and mice (0.15-0.18 mm, 9-11 mm thread insertion length).
The Houshiheisan compound prescription effectively suppresses abnormal amyloid precursor protein accumulation and reduces amyloid substance deposition. It maintains the stabilization of the internal environment of neurovascular units, minimizing injury to these units in the ischemic penumbra.
Researchers found that 3-n-butylphthalide improved neuronal morphology in the cerebral cortex and hippocampus, reducing oxidative stress caused by chronic cerebral ischemia. The compound also inhibited amyloid beta accumulation and improved cholinergic function in rats with chronic cerebral ischemia.
Researchers found that transient brain ischemia induces hyperphosphorylation of tau protein and alters its interaction with glycogen synthase kinase (GSK)-3β and protein phosphatase 2A. Lithium chloride's neuroprotective function may depend on regulating tau phosphorylation during cerebral ischemia.
Researchers found that brain-derived neurotrophic factor suppressed glucose intolerance by improving insulin receptor expression and inhibiting gluconeogenesis in the liver. This suggests a potential therapeutic hypothesis for treating glucose intolerance after cerebral ischemia.
The study reveals rutaecarpine's ability to improve neurological function after cerebral ischemia reperfusion injury. The mechanism involves reducing oxidative stress, providing a promising basis for rutaecarpine as an ideal drug for preventing and treating cerebral ischemia reperfusion injury.
Research found that 60-minute sevoflurane preconditioning reduces infarct volume and apoptotic cells, but longer durations do not provide additional benefits. The study suggests that shorter preconditioning periods may be more effective in protecting against cerebral ischemia.
Researchers found that cilostazol decreases hypoxia-inducible factor-1α and heme oxygenase-1 expression levels, protecting against cognitive impairment induced by chronic cerebral ischemic injury. Cilostazol treatment also exhibits an anti-apoptotic mechanism in the context of chronic cerebral ischemia.
The motor relearning program significantly promotes neuronal regeneration and repair, as well as angiogenesis in damaged brain tissue. This study provides a new theoretical idea for the clinical treatment of brain ischemia.
