Aberrant activation of the Hedgehog (Hh) pathway leads to development several tumors, including medulloblastoma (MB), most common pediatric brain malignancy. Hh inhibitors acting on GLI1, final effector signaling, offer a valuable opportunity overcome pitfalls existing therapies treat Hh-driven cancers. In this study, toxicity, delivery, biodistribution, and anticancer efficacy Glabrescione B (...

Maintaining blood-brain barrier integrity and minimizing neuronal injury are critical components of any therapeutic intervention following ischemic stroke. However, a low level of vitamin D hormone is a risk factor for many vascular diseases including stroke. The neuroprotective effects of 1,25(OH)2D3 (vitamin D) after ischemic stroke have been studied, but it is not known whether it prevents i...

This review presents some examples obtained by molecular techniques in the study of non-ionic reverse micelles of poly(ethylene oxide) type surfactants: tetraethylene glycol mono-ndodecyl ether (C12E4), Triton X-100, and triblok copolymers poly(ethylene oxide)-blockpoly(propylene oxide)-blockpoly(ethylene oxide) (L62 and L64 Pluronics). By using specific spectral parameters of spin, fluorescenc...

In this study, the ability of a multiwalled carbon nanotube functionalized with fluorescein isothiocyanate (MWCNT-FITC) was assessed as a prospective central nervous system-targeting drug delivery system to permeate the blood-brain barrier. The results indicated that the MWCNT-FITC conjugate is able to penetrate microvascular cerebral endothelial monolayers; its concentrations in the Transwell(...

this study demonstrates the changes in six different pathophysiological parameters such as body weight, body temperature, fecal pellet count, blood-brain barrier (bbb) permeability, plasma corticosterone level and emergence of hemorrhagic peptic ulcer spots due to exposure to high environmental heat in three different age groups of freely moving rats. methods: each age group of rats was sub div...

Tissue adhesion is a common complication after surgery. In this work, a dexamethasone loaded polymeric micelles in thermosensitive hydrogel composite (Dex hydrogel) was prepared, which combined the anti-adhesion barrier with controlled release of anti-adhesion drug. Dexamethasone (Dex) was encapsulated in polymeric micelles (Dex micelles), and then the Dex micelles were loaded into biodegradabl...

For the treatment of glioma and other central nervous system diseases, one of the biggest challenges is that most therapeutic drugs cannot be delivered to the brain tumor tissue due to the blood-brain barrier (BBB). The goal of this study was to construct a nanodelivery vehicle system with capabilities to overcome the BBB for central nervous system administration. Doxorubicin as a model drug en...
