Angiotensin AT1 receptor blockers (ARBs) and thiazolidinediones (TZDs) have become well established drugs for the treatment of major risk factors of stroke. Since several studies provided evidence that ARBs and TZDs also have additional anti-inflammatory effects, we hypothesized that a combined treatment with the ARB, candesartan, and the TZD, pioglitazone,(More)
OBJECTIVES The effects of AT1 receptor blocker, telmisartan, and the ACE inhibitor, ramipril, were tested head-to head and in combination on stroke prevention in hypertensive rats and on potential neuroprotection in acute cerebral ischemia in normotensive rats. METHODS Prevention study: Stroke-prone spontaneously hypertensive rats (SHR-SP) were subjected(More)
OBJECTIVE Ceftriaxone has been reported to reduce neuronal damage in amyotrophic lateral sclerosis and in an in-vitro model of neuronal ischaemia through increased expression and activity of the glutamate transporter, GLT1. We tested the effects of ceftriaxone on mortality, neurological outcome, and infarct size in experimental stroke in rats and looked for(More)
OBJECTIVE Pre-treatment with angiotensin receptor blockers is known to improve neurological outcome after stroke. This study investigated for the first time, whether the renin inhibitor aliskiren has similar neuroprotective effects. METHODS Since aliskiren specifically blocks human renin, double transgenic rats expressing human renin and angiotensinogen(More)
Stroke is one of the major medical burdens in industrialized countries. Animal experiments indicate that blockade of the angiotensin AT1 receptor (AT1R) improves neurological outcome after cerebral ischemia. These protective effects are partially mediated by the angiotensin AT2 receptor (AT2R). The transcription factor promyelocytic leukemia zinc finger(More)
Infections caused by classical tubercle bacilli are rare during the last years. Nevertheless, diseases caused by other mycobacteria have to be considered clinically and in diagnostic pathology especially in cases of immunosuppression and due to their potential zoonosis risk. An infection by mycobacteria was diagnosed in four animals (Mayotte Maki,(More)
Iodinated contrast media (CM) have adverse effects that may result in contrast-induced acute kidney injury. Oxidative stress is believed to play a role in CM-induced kidney injury. We test the hypothesis that oxidative stress and reduced nitric oxide in tubules are consequences of CM-induced direct cell damage and that increased local oxidative stress may(More)
Genetic factors strongly contribute to the pathogenesis of sporadic Alzheimer's disease (AD). Nevertheless, genome-wide association studies only yielded single nucleotide polymorphism loci of moderate importance. In contrast, microsatellite repeats are functionally less characterized structures within our genomes. Previous work has shown that(More)
Hypertension is a major public health problem, being one of the leading causes of death and disability worldwide and a major risk factor for cardiovascular disease. The renin-angiotensin-aldosterone system plays an important role in volume homeostasis and blood pressure regulation, and is a target for several groups of pharmaceutical agents. Telmisartan, a(More)
