Tabata training plays an important role in health promotion. Effective monitoring of exercise energy expenditure is an important basis for exercisers to adjust their physical activities to achieve exercise goals. The input of acceleration combined with heart rate data and the application of machine learning algorithm are expected to improve the accuracy of EE prediction.

Patient fibroblasts have been used for evaluation of compound efficacy, although neuronal degeneration is the hallmark of NPC disease. Here, we report the application of human NPC1 neural stem cells as a cell-based disease model to evaluate nine compounds that have been reported to be efficacious in the NPC1 fibroblasts and mouse models.

The first step in producing neural lineages from hPSCs is the generation of neural stem cells (NSCs). Current methods of NSC derivation involve the time-consuming, labor-intensive steps of an embryoid body generation or coculture with stromal cell lines that result in low-efficiency derivation of NSCs.

The signaling pathways underlying this phenomenon are not fully understood. The present study examined the role of osteopontin (OPN) in post-ischemic lateral migration of neuroblasts.

We observed an up-regulated expression of Gal-3 in the ischemic brain following transient middle cerebral artery occlusion in rats. Compared to the brain of sham-operated rats, the expression of Gal-3 was increased in the ischemic striatum at day 1 of reperfusion.

ICH model was induced by collagenase injection into the striatum of adult wild-type and osteopontin (OPN) knockout mice. In the wild-type mice, the lateral migration of neuroblasts from the ipsilateral subventricular zone (SVZ) towards the hematoma started at day 3 and continued up to day 28 after ICH.

They expressed CD29, CD44, CD73, CD105, CD166 and nestin, but not CD34, CD45, CD106 SSEA-4 or Oct3/4. Twenty million eMSCs in 1 mL of phosphate-buffered saline (PBS) were injected into the femoral veins of spontaneously hypertensive rats after transient middle cerebral artery occlusion.

The authors tested the potential of the neuropeptide substance P (SP) acting via the neurokinin-1 receptor (NK1R) in promoting the proliferation of adult rat neural progenitor cells (NPCs).
Methods: Focal ischemia was induced in spontaneously hypertensive rats by transient middle cerebral artery occlusion.
Stroke is devastating as currently no therapies are available that can prevent stroke-induced neurological dysfunction in humans. With the recent observations that acute insults to adult brain stimulate new neuronal formation in various species of animals, optimism is building for a possible regeneration of stroke-damaged brain. This article reviewed the advances in the understanding of the molecular mechanisms of the various steps of neurogenesis with an emphasis on the endogenous mediators and exogenous promoters of neural progenitor proliferation, migration and survival in the post-ischemic adult brain.

We presently report that doublecortin positive neuroblasts formed in the subventricular zone (SVZ) and the posterior peri-ventricle region migrate towards the cortical and striatal penumbra after transient middle cerebral artery occlusion (MCAO) in adult rodents. Cultured neural progenitor cells grafted into the non-infarcted area of the ipsilateral cortex migrated preferentially towards the infarct.
View Article and Find Full Text PDFThe adult mammalian brain contains resident neural progenitors in the subgranular zone of the dentate gyrus (DG) and the subventricular zone (SVZ) of the lateral ventricles. The proliferation of neural progenitors increases after focal cerebral ischemia in both of these regions, but the mechanisms that promote ischemia-induced neural progenitor proliferation are not yet understood. We hypothesize that diffusible factors from the ischemic area play a role in this process as the DG is remote from the area of infarction.

How dopamine (DA) neuronal subtypes are specified remains unknown. In this study we show a robust generation of functional DA neurons from human embryonic stem cells (hESCs) through a specific sequence of application of fibroblast growth factor 8 (FGF8) and sonic hedgehog (SHH). Treatment of hESC-derived Sox1+ neuroepithelial cells with FGF8 and SHH resulted in production of tyrosine hydroxylase (TH)-positive neurons that were mostly bipolar cells, coexpression with gamma-aminobutyric acid, and lack of midbrain marker engrailed 1 (En1) expression.
