Prijava / prijava

A series of 33 1'-(Aminoalkyl)-1,2,3,4-tetrahydronaphthalene-1-spiro-3'-pyrrolidine-2',5'-dione derivatives was tested for antiarrhythmic and toxic effects in mice and dogs. In mice, 31 compounds produced some protection against chloroform-induced tachyarrhythmias at subcutaneous doses of 100 mg/kg,

In vivo hyperoxic preconditioning prevents myocardial infarction by expressing bcl-2.

Prijava / prijava

Preconditioning with oxidative stress has been demonstrated in vitro to stimulate the cellular adaptation to subsequent severe oxidative stress. However, it is uncertain whether this preconditioning works in vivo. In the present study, we examined in vivo the beneficial effect of oxidative

Pyrrolidine dithiocarbamate inhibits translocation of nuclear factor kappa-B in neurons and protects against brain ischaemia with a wide therapeutic time window.

Prijava / prijava

Pyrrolidine dithiocarbamate (PDTC) is an antioxidant and inhibitor of transcription factor nuclear factor kappa-B (NF-kappa B). Because the role of NF-kappa B in brain injury is controversial and another NF-kappa B inhibiting thiocarbamate, DDTC, was recently shown to increase ischaemic brain

Impact of proteasome inhibitor MG-132 on expression of NF-κB, IL-1β and histological remodeling after myocardial infarction.

Prijava / prijava

The aim of the present study was to investigate the impact of carbobenzoxy-Leu-Leu-leucinal (MG-132) on myocardial remodeling in rats with myocardial infarction (MI) and investigate the possible underlying mechanisms. The rat model of MI was established, followed by administration of MG-132 (MG

Targeting blockade of nuclear factor-κB in the hypothalamus paraventricular nucleus to prevent cardiac sympathetic hyperinnervation post myocardial infarction.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Nuclear factor-κB (NF-κB) is considered to be a master inflammation regulator and involved in sympathetic neural hyperinnervation after myocardial infarction (MI). Paraventricular nucleus (PVN), acts as the sympathetic outflow tract, has been proven to play an important role during MI,

Antioxidants attenuate myocyte apoptosis in the remote non-infarcted myocardium following large myocardial infarction.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

OBJECTIVE Increased oxidative stress and myocyte apoptosis co-exist in the remote non-infarcted myocardium (RM) following a large myocardial infarction. We proposed that these phenomena are causally related. RESULTS On day 3 after induction of myocardial infarction, Sprague-Dawley rats were

Antioxidant pyrrolidine dithiocarbamate activates Akt-GSK signaling and is neuroprotective in neonatal hypoxia-ischemia.

Prijava / prijava

Pyrrolidine dithiocarbamate (PDTC), an antioxidant and inhibitor of transcription factor nuclear factor kappa-B (NF-kappaB), has been reported to reduce inflammation and apoptosis. Because PDTC was recently found to protect in various models of adult brain ischemia with a wide therapeutic time

Pyrrolidine dithiocarbamate activates p38 MAPK and protects brain endothelial cells from apoptosis: a mechanism for the protective effect in stroke?

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

The antioxidant and inhibitor of nuclear factor kappaB pyrrolidine dithiocarbamate (PDTC) potently reduces infarct size in various experimental stroke models. In addition, it has been shown to have a favourable safety profile in humans. In this study, we further investigated the mechanistic actions

Early administration of pyrrolidine dithiocarbamate extends the therapeutic time window of tissue plasminogen activator in a male rat model of embolic stroke.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

Tissue plasminogen activator (tPA) is used in fewer than 4% of patients after ischemic stroke because of its narrow therapeutic time window. We tested whether pyrrolidine dithiocarbamate (PDTC), a drug with multiple mechanisms to provide neuroprotection, can be used to extend the therapeutic time

Improvement of Left Ventricular Remodelling by Inhibition of NF-κB in a Rat Model of Myocardial Infarction.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

BACKGROUND To investigate the effects of inhibition of NF-κB activation on left ventricular (LV) remodelling in a rat model of myocardial infarction (MI). METHODS The acute MI model was established by ligation of left anterior descending coronary artery. Pyrrolidine dithiocarbamate (PDTC) (20mg/kg,

Ox-LDL influences peripheral Th17/Treg balance by modulating Treg apoptosis and Th17 proliferation in atherosclerotic cerebral infarction.

Prijava / prijava

BACKGROUND CD4(+)CD25(+) regulatory T (Treg) cells and T-helper 17 (Th17) cells play important roles in acute cerebral infarction (ACI). Our previous findings have suggested that oxidized low-density lipoprotein (Ox-LDL) could influence Treg/Th17 ratio in ACI patients. However, the mechanisms are

C1q/TNF-related protein-9 promotes macrophage polarization and improves cardiac dysfunction after myocardial infarction.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

The timely regulation of inflammatory M1 macrophage polarization toward regenerative M2 macrophages suggests the possibility of immunotherapy after myocardial infarction (MI). C1q/TNF-related protein-9 (CTRP9) has anti-inflammatory effects and can ameliorate heart function in mice after long-term

Attenuation of a delayed increase in the extracellular glutamate level in the peri-infarct area following focal cerebral ischemia by a novel agent ONO-2506.

Samo registrirani uporabniki lahko prevajajo članke

Prijava / prijava

A novel agent, ONO-2506 [(R)-(-)-2-propyloctanoic acid, ONO Pharmaceutical Co. Ltd.] was previously shown to mitigate delayed infarct expansion through inhibition of the enhanced production of S-100beta, while inducing a prompt symptomatic improvement that attained a significant level as early as
