Abstract (sommario):

Stroke is a serious cerebral vascular event and a leading cause of death and disability worldwide, and ischemic stroke is the most common type. Evidence from animal research in acute cerebral ischemia shows that a combination of neuroprotectants might be more efficacious than the single agent given individually. Both melatonin and electro-acupuncture (EA) have been suggested to be effective treatments against cerebral ischemia. However, it is unknown whether a combination of these two therapies could be beneficial against focal cerebral ischemia. In the first study, the effect of post-tr

Abstract (sommario):

Cerebral ischemia is defined as a decrease in blood flow to the brain. It is most often caused by obstruction of a cerebral blood vessel, and is recognized by the World Health Organization as the leading cause of serious adult disability and one of the top three causes of adult death worldwide. Most survivors demonstrate partial restitution of function over time, but the underlying recovery mechanism(s) remain unclear especially in a subset of patients with persistent neurological morbidities despite normal-appearing brain on neuroimaging. The optimal way to understand any human disease state

Abstract (sommario):

Cerebral ischaemia is a leading cause of disability and death world-wide. The only effective treatments are thrombolytic therapy (plasminogen activator; tPA) and hypothermia (33?C). However, tPA has limited clinical application due to its short therapeutic time window and its specific application in thrombo-embolic stroke. Moderate hypothermia (33?C) is only being used following cardiac arrest in comatose survivors. Hence more treatments are urgently required. The first step in developing new treatments is the identification and characterisation of a potential therapeutic target. Since brain d

Abstract (sommario):

Neuroprotection with anesthetics has been studied for many decades; important advances in this field have modified the way Anesthesiologists treat patients in the operating room. Animal models have played an important role in the study of ischemia in the operating room. Recent studies have demonstrated that the effect of anesthetics seems to be different in different animal models. We decided to evaluate anesthetics in a well-known model of cerebral ischemia and also in hypotensive models designed by us. We used a model of cerebral ischemia (MCAO) to test anesthetics neuroprotective effect in

Abstract (sommario):

An interruption of the blood supply to the brain, as occurs during ischemic stroke, results in a rapid decline of ATP levels and a subsequent loss of neuronal function and viability. Under physiological conditions the brain reuses ATP degradation metabolites, such as hypoxanthine, via the purine salvage pathway, to restore its ATP pool. However, the massive degradation of ATP during ischemia results in the accumulation and loss of diffusible purine metabolites and thereby leads to a reduction in the post-ischemic ATP pool size, leaving the brain more vulnerable to secondary ischemic insults (r

Background. Over the past decades metabolic profiling has become a valuable tool for the investigation of metabolic changes specific to particular diseases.

One main technical platform of metabolic profiling is based on in vitro nuclear magnetic resonance (NMR) spectroscopy: a technique that is also available fo

These behavioural deficits were similar in severity and duration although they were correlated with different patterns of reorganization seen in Golgi-stained tissue.

Stroke is a leading cause of neurological disability, often resulting in long-term motor impairments due to damage to the striatum and/or motor cortex.

This information is essential in order to improve current rehabilitation practice and develop new therapies to enhance recovery.

Abstract (sommario):

O infarto do miocárdio (IM) é a doença cardiovascular que mais causa morte e invalidez em todo o mundo. O uso de animais experimentais tem auxiliado a compreender melhor a fisiopatologia e as formas de tratamento do IM. Sabendo que as dislipidemias estão associadas com o IM e que o treinamento físico pode ser prescrito para prevenção e tratamento de doenças cardiovasculares, no presente trabalho, investigamos os efeitos de dois tipos de treinamentos físicos em um modelo experimental de dislipidemia e isquemia miocárdica. Camundongos selvagens (WT) e knockout para o receptor LDL (LDL-/-) foram

Abstract (sommario):

<p>In a mouse model of ischemic stroke, infarct volume is highly variable and strain dependent, but the natural genetic determinants responsible for this difference remain unknown. To identify genetic determinants regulating ischemic neuronal damage and to dissect apart the role of individual genes and physiological mechanisms in infarction in mice, we performed forward genetic mapping analyses of surgically induced cerebral infarct volume. We have identified multiple quantitative trait loci (QTL) that modulate infarct volume, with a major locus (<italic>Civq1 </italic>) on chromosome 7 accoun

Abstract (sommario):

Serotonin (5-hydroxytryptamine, 5-HT) is a neurotransmitter involved in the embryonic neural development and adult neurogenesis. But the effects of 5-HT on stem cells are not fully known. In this study, the effects and underlying signal pathways of 5- HT on proliferation and neural differentiation of mouse embryonic stem (ES) cells, neural progenitor (NP) cell line C 17.2 and embryonic neural stem (NS) cells were explored. Molecular analysis, immunostaining and western blotting revealed that NP/NB cells expressed the rate-limiting enzyme tryptophan hydroxylase (TPH) and produced endogenous 5-H

Abstract (sommario):

Baicalin, which is a flavonoid, was previously shown to exert neuroprotective effects against ischemic injury and oxidative insults. In this study, baicalin was found to induce neuronal differentiation on both C17.2 NSC and primary mouse NSC originated from hippocampuses of E14.5 mouse embryos. The baicalin-mediated differentiation of C17.2 NSC was noted in dose- and time-dependent manners. Baicalin-treated NSC displayed long processes of neurites. The gene expression of neuronal markers, NF-L, TUBB3 and MAP2 was also significantly increased after treated with 20 to 50 muM baicalin on C17.2 NS

博士<br>國立成功大學<br>醫學工程研究所碩博士班<br>94<br>The neuroprotective properties of melatonin were evaluated in Sprague-Dawley rats and B6 mice subjected to middle cerebral artery (MCA) occlusion. A series of experiments with delayed treatment of melatonin have been employed to examine whether exogenous melatonin offers neuroprotective action against MCA occlusion which includes ischemic brain damage not only caused by necrotic but also by apoptotic processes. Postmortem infarct volumes will be determined by quantitative image analysis of Nissl-stained brain sections and TTC-staining method. In addition, p

Abstract (sommario):

Ischaemic stroke has become one of the leading causes of death and disability in the world. Protease activated receptors (PARs, PAR-1 to PAR-4) belong to G protein coupled receptors that can be self-activated by tethered ligands (TL) revealed through proteolytic cleavage. Based on these TL, many activating peptides (APs) and antagonists have been synthesized to investigate PARs actions.<br>In the present study, the roles of PARs were examined in two models of ischaemic stroke. For the in vivo model, transient middle cerebral artery occlusion (tMCAO) was performed to establish cerebral ischaemi

Abstract (sommario):

<p>Cerebral radiation necrosis as a consequence of radiation therapy is often observed in patients several months to years after treatment. Complications include painful headaches, seizures, and in the worst-case death. Radiation necrosis is an irreversible condition with the options available to manage it all having noticeable downsides. As such, there is a critical need for better ways of either preventing the onset of necrosis and/or managing its symptoms. As radiation necrosis cannot be induced in humans for ethical reasons, a mouse model that mirrors the features of radiation necrosis obs
