Ginsenoside Rb1 attenuates mouse cerebral ischemia/reperfusion induced neurological impairments through modulation of microglial polarization

Cerebral ischemia/reperfusion causes high disability, recurrence, and mortality. Ischemic stroke is a powerful stimulus that triggers significant microglia activation.

Retinal Vessel Segmentation: A Comprehensive Review From Classical Methods to Deep Learning Advances (1982–2025)

Advanced Intelligent Systems, EarlyView.
Four decades of retinal vessel segmentation research (1982–2025) are synthesized, spanning classical image processing, machine learning, and deep learning paradigms. A meta‐analysis of 428 studies establishes a unified taxonomy and highlights performance trends, generalization capabilities, and clinical relevance.

Better 10‐Year Cerebrovascular Outcome After Transplant Than on Standard‐Care in Sickle Cell Anemia: DREPAGREFFE Trial

American Journal of Hematology, EarlyView.
ABSTRACT Management of cerebral vasculopathy in sickle cell anemia (SCA) includes standard‐care, that is, chronic transfusion (CT) or hydroxyurea, and hematopoietic cell transplantation (HCT). DREPAGREFFE‐1 (December 2010/June 2013), a French multicenter trial, was the first prospective trial comparing standard‐care to match sibling donor (MSD)‐HCT in ...

Expanding the Phenotype of TUFM‐Related Combined Oxidative Phosphorylation Deficiency 4

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Combined oxidative phosphorylation deficiency 4 (COXPD4) is a rare mitochondrial condition caused by biallelic deleterious variants in the nuclear‐encoded gene TUFM. To date, most individuals with COXPD4 have presented with encephalopathy, hypotonia, and abnormal brain imaging. Many of the reported individuals died in infancy. We aim to expand

Severe ADEM‐Like Neuroinflammatory Disease and Cerebrovascular Fragility With Recurrent Pseudoaneurysms and Moyamoya in a Familial Germline CBL Mutation: Expanding the Clinical Phenotype

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Heterozygous germline variants in CBL disrupt its function as a negative regulator of the Ras/MAPK pathway, classically predisposing to Juvenile myelomonocytic leukemia (JMML) and moyamoya. We describe two affected siblings carrying a paternally inherited CBL variant (c.1210 T> C, p.

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

Transcriptomics, single-cell sequencing and spatial sequencing-based studies of cerebral ischemia

European Journal of Medical Research
With high disability and mortality rate as well as highly complex pathogenesis, cerebral ischemia is highly morbid, prone to recurrence. To comprehensively understand the pathophysiological process of cerebral ischemia and to find new therapeutic ...

CUMULATIVE EFFECT OF REPETITIVE ISCHEMIA: PATHOPHYSIOLOGICAL FINDINGS

, 1994
The cumulative effect of ischemia on the brain was investigated in cats using a repetitive transient global ischemia model. The cats were submitted to three series of repetitive ischemia of 5.0, 7.5 and 10.0-minute durations at I-hour intervals by ...
