It has not been reported whether thiamine deficiency (TD) affects hippocampal neurogenesis or not. Here, we explored the influence of TD at early pre-pathological lesion stage on hippocampal neurogenesis and the correlation between affected hippocampal neurogenesis and cognitive dysfunction. We prepared TD mouse model by feeding a thiamine-depleted diet. Learning and memory functions of TD mice...

It has been proven that nuclear factor-kappa B (NF-κB) is activated as a well-known transcription factor after subarachnoid hemorrhage (SAH). However, the panoramic view of NF-κB activity after SAH remained obscure. Cultured neurons were signed into control group and six hemoglobin- (Hb-) incubated groups. One-hemorrhage rabbit SAH model was produced, and the rabbits were divided randomly into ...

BACKGROUND AND PURPOSE The seleno-organic compound ebselen has both antioxidant and anti-inflammatory properties. Although ebselen has been shown to protect the brain against stroke, it is unclear how ebselen provides neuroprotection. In the present study the authors examined whether ebselen inhibits neuronal apoptosis resulting from transient focal cerebral ischemia in mice. The cytochrome c r...

Neurodegeneration together with a reduction in neurogenesis are cardinal features of Alzheimer's disease (AD) induced by a combination of toxic amyloid-β peptide (Aβ) and a loss of trophic factor support. Amelioration of these was assessed with diverse neurotrophins in experimental therapeutic approaches. The aim of this study was to investigate whether intranasal delivery of plasma rich in gro...

We present a novel approach for automated detection of neuron somata. A three-step processing pipeline is described on the example of confocal image stacks of NeuN-stained neurons from rat somato-sensory cortex. It results in a set of position landmarks, representing the midpoints of all neuron somata. In the first step, foreground and background pixels are identified, resulting in a binary ima...

To investigate the neuroprotective effect of melatonin against hypoxic-ischemic brain injury in neonatal rats and the mechanisms involved. Neonatal rats with hypoxic-ischemic brain injury were treated with melatonin at 0.01 mg per gram body weight for 7 days. The damaged area and volume of the rat brains were quantified by threedimensional (3D) reconstructive technology. Apoptosis, regeneration...

Acupuncture has been used for patients with stroke and post-stroke rehabilitation for thousands of years. Previous studies reported that acupuncture enhanced stroke recovery through neurogenesis. Hence, we conducted a systematic review and meta-analysis for preclinical studies to assess the current evidence for acupuncture effect on neurogenesis in treating ischaemic stroke. Studies were obtain...

Complement activation plays important roles in the pathogenesis of central nervous system (CNS) diseases. Patients face neurological disorders due to the development of complement activation, which contributes to cell apoptosis, brain edema, blood-brain barrier dysfunction and inflammatory infiltration. We previously reported that induced neural stem cells (iNSCs) can promote neurological funct...
