Active targeting towards and inside the brain based on nanoparticles: A Review.

Active targeting towards and inside the brain based on nanoparticles: A Review. Curr Pharm Biotechnol. 2019 Dec 02;: Authors: Rabiei M, Kashanian S, Samavati SS, Jamasb S, McInnes SJP Abstract Treatment of neurological diseases using systemic and non-surgical techniques presents a significant challenge in medicine. This challenge is chiefly associated with the condensation and coherence of the brain tissue. The coherence structure of the brain is due to the presence of the blood brain barrier (BBB), which consists of a continuous layer of capillary endothelial cells. The BBB prevents most drugs from entering the brain tissue and is highly selective, permitting only metabolic substances and nutrients to pass through. Although this challenge has caused difficulties for the treatment of neurological diseases, it has opened up a broad research area in the field of drug delivery. Via the utilization of nanoparticles (NPs), nanotechnology can provide the ideal condition for passing through the BBB. NPs with suitable dimensions and optimum hydrophobicity and charge, as well as appropriate functionalization, can accumulate in the brain. Furthermore, NPs can facilitate the targeted delivery of therapeutics into the brain areas involved in Alzheimer's disease, Parkinson's disease, stroke, glioma, migraine, and other neurological disorders. This review describes these methods of actively targeting specific areas of the brain. PMID: 31793421 [PubMed - as suppli...

AbstractThis is a letter to the Editor concerning the recently published article by Zerem et al. The paper described a 12yo female with multisystem mitochondrial disorder (MID) due to the compound heterozygous variants c.1963_1964dupAT and p.Ile382Met inOPA1 manifesting phenotypically with congenital nystagmus, developmental delay, visual impairment, gait ataxia, epilepsy, a stroke-like episode (SLE) with encephalopathy and vomiting, and hearing impairment. This interesting case could be more meaningful by providing more information about the treatment of the SLE/stroke-like lesion (SLL), about the morphological characteri...

High blood pressure: A common diagnosis, that shows hardly any symptoms, but can be deadly. Hardened arteries and blood forced too hard against artery walls can lead to a heart attack or stroke. Fortunately, there are lifestyle improvements that can lower blood pressure and potentially save your life.

ConclusionsThese findings suggest that MXYF inhibits autophagy after OGD/R-induced PC12 cell injury through the AMPK-mTOR pathway. Thus, MXYF might have therapeutic potential in treating ischemic stroke.Graphical abstract

This study aims to test the hypothesis that induced spinal sensitization could be more pronounced in patients affected by high-frequency migraine (HF-MIG) with respect to low-frequency migraine (LF-MIG). We enrolled 28 patients with LF-MIG (1-5 migraine days/month), 19 patients with HF-MIG (6-14 migraine days/month), and 21 healthy controls (HCs). Spinal sensitization was evaluated with the neurophysiological recording of the temporal summation threshold (TST) of the nociceptive withdrawal reflex at the lower limb. Temporal summation threshold was recorded at baseline and 30, 60, and 120 minutes after NTG administration (0...

Publication date: Available online 21 January 2020Source: Biocybernetics and Biomedical EngineeringAuthor(s): P.M. Siva Raja, Antony Viswasa raniAbstractIn medical image processing, brain tumor detection and segmentation is a challenging and time-consuming task. Magnetic Resonance Image (MRI) scan analysis is a powerful tool in the recent technology that makes effective detection of the abnormal tissues from the brain. In the brain image, the size of a tumor can be varied for different patients along with the minute details of the tumor. It is a difficult task to diagnose and classify the tumor from numerous images for the...

However, as the results yielded by this increased research have hitherto conflicted, we performed an updated meta-analysis of reports on the relationships between VDR polymorphisms and PD published before October 2019 that we collected from the PUBMED, EMBASE, EBSCO, China N...

In this study, using a mouse model of ischemic strokevia transient middle cerebral artery occlusion (tMCAO), we found that Hes1 was induced following brain injury, and that siRNA-mediated knockdown of Hes1 increased the cerebral infarction and worsened the neurological outcome, suggesting that Hes1 knockdown exacerbates ischemic stroke. In addition, mechanistically, Hes1 knockdown promoted apoptosis and activated the PERK/eIF2 α/ATF4/CHOP signaling pathway after tMCAO. These results suggest that Hes1 knockdown promotes ER stress-induced apoptosis. Furthermore, inhibition of PERK with the specific inhibitor GSK2606414...
