Central nervous system acting drugs, when administered intravenously, cannot show their effect in the brain due to the difficulty in crossing the blood-brain barrier (BBB). Levodopa is one of those drugs that are used to treat Parkinson's disease. In this study, a new liposomal levodopa delivery system that is modified with maltodextrin was developed in order to target and enhance transport through the BBB. An antioxidant, glutathione, was co-loaded in liposomes as a supportive agent and its effect on liposome stability and delivery was investigated. Glutathione co-loading had a positive effect on the viabilities of 3T3 and SH-SY5Y cells. Maltodextrin targeted liposomes showed high in vitro levodopa passage in the parallel artificial membrane permeability assay and had superior binding to MDCK cells. Results suggest that maltodextrin modification of liposomes is an effective way of targeting the BBB and the developed liposomal formulation would improve brain delivery of central nervous system agents.

Antinociceptive effects of hydromorphone, bupivacaine and biphalin released from PLGA polymer after intrathecal implantation in rats

Intraspinal drug delivery, based on the concept of controlling pain by delivering drug to a nociceptive target rich in opioid and other relevant receptors is increasingly used clinically. The therapeutic ratio for opioids or other centrally acting agents is potentially greater if they are administered intrathecally (i.t.) than outside the central nervous system (CNS). The present study was designed with the ultimate goal of formulating a controlled release system for intrathecal analgesia characterized by e...
Unilateral deep brain stimulation suppresses alpha and beta oscillations in sensorimotor cortices

Deep brain stimulation (DBS) is an established therapy to treat motor symptoms in movement disorders such as Parkinson's disease (PD). The mechanisms leading to the high therapeutic effectiveness of DBS are poorly understood so far, but modulation of oscillatory activity is likely to play an important role. Thus, investigating the effect of DBS on cortical oscillatory activity can help clarifying the neurophysiological mechanisms of DBS. Here, we aimed at scrutinizing changes of cortical oscillatory activit...
SRC family kinase inhibitors antagonize the toxicity of multiple serotypes of botulinum neurotoxin in human embryonic stem cell-derived motor neurons.

Botulinum neurotoxins (BoNTs), the causative agents of botulism, are potent inhibitors of neurotransmitter release from motor neurons. There are currently no drugs to treat BoNT intoxication after the onset of the disease symptoms. In this study, we explored how modulation of key host pathways affects the process of BoNT intoxication in human motor neurons, focusing on Src family kinase (SFK) signaling. Motor neurons derived from human embryonic stem (hES) cells were treated with a panel of SFK inhibitors a...
Exergaming and rehabilitation: A methodology for the design of effective and safe therapeutic exergames
PIROVANO, Michele; Sürer, Elif; MAINETTI, Renato; LANZİ, Pier Luca; BORGHESE, N. Alberto (2016-05-01)
We present here a comprehensive definition of therapeutic exergames from which a methodology to create safe exergames for real therapy pathways is derived. Three main steps are identified. (I) A clear identification of all the exercise requirements, not only in terms of goals of the therapy, but also in terms of additional constraints. Characteristic parameters for determining the challenge level and to assess progression are also defined in this phase. (II) The exercise is transformed into a Virtual Exerci...
Missense Genetic Polymorphisms of Microsomal (EPHX1) and Soluble Epoxide Hydrolase (EPHX2) and Their Relation to the Risk of Large Artery Atherosclerotic Ischemic Stroke in a Turkish Population
Demirdogen, Birsen Can; Micoogullari, Yagmur; Ozcelik, Aysun Turkanoglu; Adalı, Orhan (2020-01-01)
Purpose: Soluble epoxide hydrolase (sEH) and microsomal epoxide hydrolase (mEH) both catalyze the metabolism of epoxyeicosatrienoic acids (EETs), lipid signaling molecules that are protective against ischemic brain injury owing to their participation in the regulation of vascular tone and cerebral blood flow. In addition, mEH metabolizes polycyclic aromatic hydrocarbons, one of the causative factors of atherosclerotic lesion development. In this study, we aimed to investigate the association of enzyme activ...
