The antiarrhythmic dipeptide, GAP-134, ([2S,4R]-1[2-aminoacetyl]-4-benzamido-pyrrolidine-2-carboxylic acid) was evaluated in canine ischemia/reperfusion model. In dogs subjected to 60-minute ischemia and 4-hour reperfusion, GAP-134 was administered 10 minutes before reperfusion as a bolus +
OBJECTIVE
In the present study, we have investigated the neuroprotective potential of 6hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid (Trolox), in middle cerebral artery occlusion (MCAO) induced focal cerebral ischemia.
METHODS
Sprague-Dawley rats were subjected to 2 hours of MCAO followed by
Blocking of poly(ADP-ribose) polymerase (PARP)-1 has been expected to protect the heart from ischemia-reperfusion injury. We have recently identified a novel and orally active PARP-1 inhibitor, KR-33889 [2-[methoxycarbonyl(4-methoxyphenyl)-methylsulfanyl]-1H-benzimidazole-4-carboxylic acid amide],
The purpose of the study was to assess effects of the competitive N-methyl-D-aspartate (NMDA) receptor antagonist D-(E)-4-(3-phosphonoprop-2-enyl)piperazine-2-carboxylic acid (D-CPPene) upon focal cerebral infarction and brain oedema in the rat. Focal cerebral ischaemia was produced by permanent
We previously reported that 5-methoxyindole-2-carboxylic acid (MICA) could induce preconditioning effect in the ischemic brain of rat. In the present study, we addressed the question of whether MICA could also trigger a postconditioning effect in ischemic stroke. To this end, MICA (100 mg/kg body
The interest of researchers for ligands of the endothelin receptors ETA and ETB is due to their extensive therapeutic potential. In particular, receptor antagonists are useful in a number of diseases such as pulmonary hypertension, acute myocardial infarction, congestive heart failure, renal
The objective of this study was to investigate a possible role of mitochondrial dihydrolipoamide dehydrogenase (DLDH) as a chemical preconditioning target for neuroprotection against ischemic injury. We used 5-methoxyindole-2-carboxylic acid (MICA), a reportedly reversible DLDH inhibitor, as the
The purpose of this study was to investigate the effect of (3S)-7-chloro-3-[2-((1R)-1-carboxyethoxy)-4-aminomethylphenyl]aminocarbonylmethyl-1,3,4,5-tetrahydrobenz[c,d]indole-2-carboxylic acid hydrochloride (SM-31900), an antagonist with high selectivity and affinity for the NMDA receptor
6-[4-(1-Cyclohexyl-1H-tetrazol-5-yl)butoxy]-3,4-dihydro-2-(1H)quinolinone (cilostazol), a phosphodiesterase type 3 (PDE III) inhibitor, activates cAMP-dependent protein kinase A (PKA). The cAMP/PKA pathway potentiates the opening of mitochondrial Ca(2+)-activated K(+) (mitoK(Ca)) channels and
Four Hg-203-mercurated phthaleins were prepared, purified, and compared with [203Hg] mercuric nitrate, [3H] phenolphthalein [203Hg] hydroxymercurifluorescein and Tc-99m-pyrophosphate in a rat model of myocardial necrosis to determine their specificities for damaged myocardium. The ratios of damaged
It is uncertain whether omega-3 fatty acids are beneficial in statin-treated patients. Epanova is a mix of omega-3 free fatty acids, not requiring co-ingestion with food, which can lower triglycerides by up to 31%. STRENGTH will examine whether Epanova 4 g daily reduces the rate of cardiovascular
The inhibition of the Na+/H+ exchanger during cardiac ischemia and reperfusion has been shown to be beneficial for the preservation of the cellular integrity and functional performance. The aim of the present investigation was to come up with potent and selective benzoylguanidines as NHE inhibitors
BACKGROUND
The elevated risk of triggering a myocardial infarction by smoking cannabis is limited to the first 2 h after smoking.
OBJECTIVE
To examine the possible role of cannabis in cardiac deaths. CASES AND RESULTS: From 3,193 coroners' cases over 2 years, there were 13 cases where the clinical
A 37-year-old, one-pack-per-day tobacco smoker collapsed and died at home. At autopsy, he had an occluded left anterior descending coronary artery. Δ(9)-Tetrahydrocannabinol-carboxylic acid was found in his urine but no cannabinoids were detected in his blood. Misadventure was the inquest verdict on
