alginate/stroke

The miniature pig is an optimal animal model for studying nervous system disease because of its physiologic and pathologic features. However, the rete mirabile composed of arteries and veins at the skull base limits their application as a model of ischemic stroke by middle cerebral artery occlusion.

Marine brown macroalgae is a promising source of material for biorefining, and alginate is one of the major components of brown algae. Despite the huge potential availability of alginate, no system has been reported for the production of valuable compounds other than ethanol from alginate, hindering

OBJECTIVE Choroid plexus (CP) secretes a cocktail of neurotrophic factors. In the present study, CP from neonatal pigs was encapsulated within alginate microcapsules for in vitro and in vivo neuroprotective studies. METHODS In vitro studies involved serum deprivation of rat embryonic cortical

Regenerative therapies in Parkinson's disease aim to slow neurodegeneration and re-establish damaged neuronal circuitry. Neurotrophins are potent endogenous regulators of neuronal survival, development and regeneration. They represent an attractive regenerative

Delivery of neurotrophic molecules to the CNS is a potential treatment strategy for preventing the neuronal loss accompanying many neurological disorders. Choroid plexus (CP) epithelial cells secrete a cocktail of neurotrophic factors, and encapsulated CP transplants are neuroprotective in animal

The aim of this study was to investigate the suitability of irreversible hydrocolloid impression material (alginate) as a test food to measure the chewing performance of complete denture wearers. Twenty edentulous subjects participated, 11 of whom were re-tested after new dentures were provided. A

Mechanical compression has been shown to impact cell activity; however a need for a single device to perform a broader range of parametric studies exists. We have developed an oscillatory displacement controlled device to uniaxially strain cell constructs under both static and dynamic compression

BACKGROUND Local biological drug delivery in the brain is an innovative field of medicine that developed rapidly in recent years. Our report illustrates a unique case of de novo development of a cerebral arteriovenous malformation (AVM) after implantation of genetically modified allogeneic

Delivery of neurotrophic molecules to the brain has potential for preventing neuronal loss in neurodegenerative disorders. Choroid plexus (CP) epithelial cells secrete numerous neurotrophic factors, and encapsulated CP transplants are neuroprotective in models of stroke and Huntington's disease

Patients who undergo percutaneous endoscopic gastrostomy (PEG) placement are often on antiplatelet therapy. There is a potential risk of infarction if these medications are discontinued.The guidelines of the Japan Gastroenterological Endoscopy Society, classify PEG as an operation associated with a

During the late 1980s and early 1990s, much research effort in the pharmaceutical industry was focused on the development of novel systems for sustained delivery of effective, but intrinsically short-acting, antihypertensive agents. This advance was motivated by a desire both to improve trough/peak

The present study examined the neuroprotective effects of choroid plexus isolated from adult rats and encapsulated within alginate microcapsules. In vitro, conditioned media from cultured choroid plexus produced a marked, dose-dependent protection of embryonic cortical neurons against serum

Local myocardial application of inotropes may allow the study of pharmacologically augmented central myocardial contraction in the absence of confounding peripheral vasodilating effects and alterations in heart loading conditions. Novel alginate epicardial (EC) drug releasing platforms were used to

Progesterone is a sex hormone which shows neuroprotective effects in different neurodegenerative disorders, including Parkinson's disease, stroke, and Alzheimer's disease. However, the pharmacokinetic limitations associated with the peripheral administration of this molecule highlight the need for

BACKGROUND Untreated ischemic stroke can lead to severe morbidity and death, and as such, there are numerous endovascular blood-clot removal (thrombectomy) devices approved for human use. Human thrombi types are highly variable and are typically classified in qualitative terms - 'soft/red,'
