Logáil Isteach / Cláraigh

Hypoxia-inducible factor (HIF)-1α is a transcription factor that is critical for tissue adaption to hypoxia and inflammation. Previous studies had indicated that normoxic activation of HIF-1α in cancer involves inhibition or mutation of the metabolic enzyme succinate dehydrogenase (SDH). We have

Insulin edema in diabetes mellitus associated with the 3243 mitochondrial tRNA(Leu(UUR)) mutation; case reports.

We encountered a patient with diabetes mellitus due to the 3243 mitochondrial tRNA mutation(DM-Mt3243), who developed insulin edema and hepatic dysfunction after starting insulin. Such a rare phenomenon was unlikely to be a fortuitous coincidence in mitochondrial diabetes, as none in 197 non-mutant

Redistribution of the flux-control coefficients in mitochondrial oxidative phosphorylations in the course of brain edema.

This work describes the control exerted by dicarboxylate carrier and succinate dehydrogenase activities on the oxidative phosphorylations in rabbit brain mitochondria as an edema develops. Vasogenic edema leads to an uncompetitive inhibition of succinate dehydrogenase activity and to a large

A two-hour window for hypothermic modulation of early events that impact delayed opening of the rat blood-brain barrier after ischemia.

Logáil Isteach / Cláraigh

Opening of the blood-brain barrier (BBB) and consequent edema are known to intensify 24-72 h after ischemic stroke, and research on potential ameliorative therapies in animal models may lead to improved clinical treatments to prevent brain swelling and the secondary damage it causes. In this study,

Calcium oxalate crystals in acute ethylene glycol poisoning: a confocal laser scanning microscope study in a fatal case.

Logáil Isteach / Cláraigh

BACKGROUND The severity of ethylene glycol toxicity is related to the metabolic acidosis resulting from the biotransformation of ethylene glycol into toxic metabolites. Glycolic acid causes severe acidosis and oxalate precipitates as calcium oxalate in the kidneys and other tissues. METHODS An adult

Adult-onset MELAS. Evidence for involvement of neurons as well as cerebral vasculature in strokelike episodes.

BACKGROUND We report a 46-year-old woman with implications regarding pathogenesis of strokelike episodes in MELAS (mitochondrial encephalomyopathy, lactic acidosis, and strokelike episodes). She had a 10-month history of episodic seizures, strokes, cognitive decline, vomiting, and ileus. She also

Effects of electroacupuncture of different intensities on energy metabolism of mitochondria of brain cells in rats with cerebral ischemia-reperfusion injury.

OBJECTIVE To observe the effects of electroacupuncture (EA) of different intensities on lactate dehydrogernase (LDH), succinate dehydrogenase (SDH) and ATPase in brain tissue of rats with cerebral ischemia-reperfusion injury (CI/R). METHODS Forty male SD rats were uniformly randomized into sham

Experimental model for ophthalmopathy in BALB/c and outbred (CD-1) mice genetically immunized with G2s and the thyrotropin receptor.

In an attempt to develop an animal model for thyroid-associated ophthalmopathy (TAO) we have genetically immunized BALB/c and outbred (CD-1) mice with cDNAs encoding the thyroid and eye muscle shared protein G2s and full length human thyrotropin receptor (TSHr). Firstly, BALB/c mice were immunized

OBJECTIVE To investigate the pathological changes in the neuromuscular junction during ischemia-reperfusion (IR) in the skeletal muscle. METHODS Forty-eight healthy adult Wistar rats (24 male, 24 female) were equally randomised into the following 6 groups: Group A (control group): no

Logáil Isteach / Cláraigh

The effects of revascularization on the morphological aspects of myocardial infarction have been studied in 87 animals. After permanent ligation of a coronary artery, the aspects are stereotyped and the histo-enzymatic and ultrastructural evolution is quite well known. On the contrary, early

Ultrastructural and cytochemical changes in the heart of iron-deficient rats.

Male Sprague-Dawley rats aged 3 weeks that were maintained on an iron-deficient diet for 4-5 weeks developed severe anemia with markedly reduced hemoglobin levels (3.94 +/- 0.14 Hb g% versus controls 12.9 +/- 0.11 Hb g%). Iron-deficiency resulted in marked cardiac hypertrophy (cardiomegaly). On

Chronic intraperitoneal injection of cadmium and copper salts produces cardiotoxic effects of various degree. The degree of the muscular tissue lesion in the ventricles and atria is inverse to the number of luminescent nervous terminals. Changes in the adrenergic fibers are accompanied with certain

The distribution of succinate dehydrogenase (SDH) activity and the corresponding changes in specific gravity were studied in cats with experimental focal ischemia. Two hours of tandem occlusion of the middle cerebral artery (MCA) and the conunon carotid artery produced a scattered reduction of SDH
