Rapamycin prevents cerebral stroke by modulating apoptosis and autophagy in penumbra in rats

Sign Up to like & get
recommendations! Published in 2018 at "Annals of Clinical and Translational Neurology"

DOI: 10.1002/acn3.507

Abstract: Whether activation or inhibition of the mTOR pathway is beneficial to ischemic injury remains controversial. It may result from the different reaction of ischemic penumbra and core to modulation of mTOR pathway after cerebral ischemia–reperfusion… read more here.

DOI: 10.1007/s00330-020-07485-2

Abstract: To quantitatively evaluate the volume of the ischemic penumbra using susceptibility-weighted imaging and mapping (SWIM) of asymmetrical prominent cortical veins (APCVs) in patients with acute ischemic stroke. Eighty-five eligible patients with acute ischemic stroke on… read more here.

recommendations! Published in 2019 at "Acta Neurochirurgica"

DOI: 10.1007/s00701-019-03914-4

Abstract: BackgroundRecent aspiration thrombectomy devices tend to have a more flexible distal tip and larger bore for easy target access and effective reperfusion. Here, this study primarily focused on the efficacy and safety of the SOFIA… read more here.

DOI: 10.1021/acschemneuro.7b00382

Abstract: Stroke exacts a heavy financial and economic burden, is a leading cause of death, and is the leading cause of long-term disability in those who survive. The penumbra surrounds the ischemic core of the stroke… read more here.

DOI: 10.1051/0004-6361/201628547

Abstract: Context. We recently presented evidence that stable umbra-penumbra boundaries are characterised by a distinct canonical value of the vertical component of the magnetic field, B stable ver . In order to trigger the formation of… read more here.

DOI: 10.1097/md.0000000000006091

Abstract: Rationale: The ischemic penumbra assessment is essential for the subsequent therapy and prediction of evolution in patients with acute ischemic infraction. Although controversial as a perfect equivalence to penumbra, perfusion-weighted imaging (PWI)-diffusion-weighted imaging (DWI) mismatch… read more here.

DOI: 10.1111/bpa.13110

Abstract: Reperfusion therapy has improved the outcomes of ischemic stroke but also emphasized the importance of ischemic penumbra. However, blood biomarkers are currently unavailable for this region. Adrenomedullin (ADM) is a neuroprotective peptide, secreted in a… read more here.

DOI: 10.1117/1.jmi.10.1.014001

Abstract: Abstract. Purpose The size and location of infarct and penumbra are key to decision-making for acute ischemic stroke (AIS) management. CT perfusion (CTP) software estimate infarct and penumbra volume using contralateral hemisphere relative thresholding. This… read more here.
