Cerebral microbleeds (CMBs) have been identified as an important manifestation and diagnostic marker of cerebrovascular disease, but there are also some controversies about the impact of CMBs on cognition. The current cross-sectional study aimed to clarify the relationship between CMBs and cognitive impairment in patients with ischemic cerebrovascular disease. One hundred and fifty patients with lacunar infarction or transient ischemic attack were screened, and all of them were scanned by brain MRI. In the end, 125 patients who were divided into a CMBs group and a non-CMBs group were selected and completed the cognitive tests...

Accumulating evidence suggests that Che-1 is a strong antiapoptotic protein and can protect cells against various insults. However, whether Che-1 is involved in the protection of neurons against cerebral ischemia/reperfusion injury remains unclear. In this study, we aimed to investigate the potential role of Che-1 in regulating cerebral ischemia/reperfusion injury-induced neuronal injury using the oxygen-glucose deprivation and reoxygenation (OGD/R) model in vitro. We found that Che-1 expression was induced in neurons following OGD/R treatment...

Golgi-specific DHHC type zinc finger protein (GODZ) is a member of the DHHC protein family, and its enzymatic activity is regulated by fibroblast growth factor or Src kinase-mediated tyrosine phosphorylation. In cultured neurons, GODZ affects the numbers of calcium ions channels, α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptors, N-methy-D-aspartate receptors, and γ-aminobutyric acid A receptors on postsynaptic membrane by palmitoylation, thus modulating synaptic plasticity. As the change in synaptic plasticity plays a role in epilepsy, GODZ may play roles in epilepsy...

Microglial activation plays a critical role in spinal cord ischemic reperfusion injury. Spinal cord stimulation preconditioning and postconditioning has shown spinal cord protection in ischemic reperfusion injury in animal studies. However, whether spinal cord stimulation could reduce microglial activation is still unclear. In this study, rabbits experienced 28-min infrarenal aorta occlusion and reperfusion for 8 h, 1, 3, and 7 days correspondingly. Immediately after reperfusion, rabbits received spinal cord stimulation of 2 or 50 Hz for 30 min and daily for a week...

The neurotoxicity of aggregated amyloid β (Aβ) has been implicated as a critical cause in the pathogenesis of Alzheimer's disease. In a previous work, we have shown that low-molecular-weight chondroitin sulfate (LMWCS), a derivative of chondroitin sulfate, protected the SH-SY5Y neuroblastoma cells from Aβ25-35-induced neurotoxicity, decreased intracellular reactive oxygen species level and inhibited the cell apoptosis. However, the underlying mechanism of the antioxidative effect of LMWCS in the SH-SY5Y cells has not been well explored...

Previous studies have indicated that spinal cord injury can induce autophagy. To a certain extent, increased autophagy has a protective effect on neurons. Early hormone therapy is well recognized as a treatment for spinal cord injury. However, whether the protective effect of autophagy is important in recovery from spinal cord injury remains unclear. In this study, we established an in-vitro model of spinal cord injury to study the effects of dexamethasone on mechanical injury, autophagy, and apoptosis in spinal cord neurons...

BC200 is a long noncoding RNA expressed at high levels in the Alzheimer's disease (AD), and blocking of BC200 by siRNA is assumed to be an effective method for various disease therapy. We have established an AD cell model overexpressing amyloid β-peptide (Aβ)1-42 to observe the effects of BC200 on the cell viability and apoptosis, and to investigate the associated underlying mechanisms. Efficient knockdown and overexpression of BC200 were established using BC200 siRNA and BC200 mimics, respectively. Cell viability following BC200 knockdown and overexpression was assessed by 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyltetrazolium bromide assay, and cell apoptosis was monitored by flow cytometry...

Long noncoding RNAs have been implicated in oligodendrocyte myelination and oligodendrocyte maturation, but their roles in normal oligodendrocyte differentiation are not fully defined. Here, we report a novel nonprotein-coding RNA, named lnc158, discovered in mouse oligodendrocytes identified in subependymal ventricular zone tissue by single-cell RNA sequencing. Lnc158 is an endogenous antisense transcript of nuclear factor-IB (NFIB) and complementary to 3' untranslated region of NFIB mRNA. NFIB is a member of the nuclear factor-I family and is essential in the development of many organs such as brains and lungs...

Modulation of the soleus H-reflex following galvanic vestibular stimulation (GVS) has been used to evaluate vestibulospinal tract function. It is not known whether this modulation is because of vestibular stimulation and/or cutaneous stimulation, and the suitable stimulating intensity of GVS for the modulation is not established. We investigated the influence of GVS intensity and cutaneous stimulation on the soleus H-reflex in healthy adults. We applied cathodal GVS (at 1, 2, and 3 mA) or 3-mA cutaneous stimulation as a conditioning stimulation in a random order to 17 individuals in the prone position with the head facing forward, and we examined the changes in the right soleus H-reflex amplitude...

Previous research has revealed an age-related shift in how individuals recall events from their personal past, with older adults reporting events that are more positive than young adults. We recently showed that age-by-valence interactions may be partially driven by a prefrontally mediated control mechanism recruited by older adults during retrieval of negative laboratory events to reduce phenomenological richness. Specifically, age was associated with greater increases in prefrontal recruitment during retrieval of negative relative to positive events, with this recruitment linked to decreases in hippocampal activity and subjective vividness ratings...

Hirschsprung disease (HSCR) is a complex genetic disorder of the enteric nervous system that is characterized by a complete loss of the neuronal ganglion cells in the intestinal tract. It is one of the most frequent causes of congenital intestinal obstruction and more than 80% of the causative mutations are in RET. Here, we identified a new RET mutation in a patient and established a cell model that can be used to elucidate the pathogenesis of HSCR. Peripheral blood was collected from a patient who was clinically and pathologically diagnosed with HSCR with a heterozygous deletion mutation (c...

The central cholinergic nervous system plays an important role in cognition, with acetylcholine hypofunction considered to be a major factor of dementia. Botulinum toxin type A (BoNT/A), a potent poison secreted by Clostridium botulinum, is used widely for dystonia treatment and facial cosmesis. BoNT/A injection inhibits acetylcholine release in the neuromuscular junction through cleavage of synaptosomal-associated protein of 25 kDa in cholinergic terminals. Furthermore, beyond the injection site, BoNT/A undergoes retrograde transport and transcytosis to the central nervous system from peripheral cholinergic terminals...

Dysregulation of the PI3K/Akt/mTOR signaling cascade has been associated with the pathology of neurodegenerative disorders, specifically Alzheimer's disease (AD). Both in-vivo models and post-mortem brain samples of individuals with AD have commonly shown hyperactivation of the pathway. In the present study, we examine how neuron subset-specific deletion of Pten (NS-Pten) in mice, which presents with hyperactive mammalian target of rapamycin (mTOR) activity, affects the hippocampal protein levels of key neuropathological hallmarks of AD...
