Xenopus embryos injected with tritiated thymidine throughout the stages of embryonic retinal neurogenesis showed that more than 95% of the embryonic retinal cells are born within a 25 hr period. While there are shallow central to peripheral, dorsal to ventral, and interlaminar gradients of neurogenesis in these eyes, throughout most of this 25 hr period,(More)
Recent epidemiological studies show a strong reduction in the incidence of Alzheimer's disease in patients treated with cholesterol-lowering statins. Moreover, elevated Abeta42 levels and the varepsilon4 allele of the lipid-carrier apolipoprotein E are regarded as risk factors for sporadic and familial Alzheimer's disease. Here we demonstrate that the(More)
To rapidly respond to invading microorganisms, humans call on their innate immune system. This occurs by microbe-detecting receptors, such as CD14, that activate immune cells to eliminate the pathogens. Here, we link the lipopolysaccharide receptor CD14 with Alzheimer's disease, a severe neurodegenerative disease resulting in dementia. We demonstrate that(More)
Subarachnoidal release of inflammatory cytokines (interleukin (IL)-1beta, IL-6, and tumour necrosis factor (TNF)-alpha) was characterised in 35 patients with subarachnoid haemorrhage (SAH) and control subjects and compared with development of complicating haemodynamic abnormalities in basal cerebral arteries and clinical outcome. Serial analysis allowed the(More)
A reliable and reproducible method for precisely predicting the neurological outcome of patients with hypoxic-ischemic encephalopathy after cardiac arrest is urgently needed in neurological intensive care units. We prospectively investigated the predictive power of serum concentrations of neuron-specific enolase (NSE) and protein S-100B (S-100B) measured on(More)
In schizophrenia, elevations of serum and CSF S100B levels have been reported and related to state of the disease and negative symptoms. In elderly chronic schizophrenic inpatients with stable medication, S100B may be increased and correlated to psychopathology and neuropsychological deficits. We have measured serum levels of S100B in 41 elderly, chronic(More)
INTRODUCTION The aim of this study was to evaluate the diagnostic and prognostic value of presepsin in patients with severe sepsis and septic shock during the first week of ICU treatment. METHODS In total, 116 patients with suspected severe sepsis or septic shock were included during the first 24 hours of ICU treatment. Blood samples for biomarker(More)
Recent epidemiological studies suggest that inhibitors of 3-hydroxy-3-methyl-glutaryl CoA reductase, so-called statins, are effective in lowering the prevalence of Alzheimer's disease. Whether the effect of statins is due to a local inhibition of cholesterol synthesis in the brain or whether it is mediated by the reduced levels of cholesterol in the(More)
Peritonitis with Candida albicans is an important complication of bowel perforation and continuous ambulatory peritoneal dialysis. To define potential virulence factors, we investigated 50 strains of C. albicans in a murine peritonitis model. There was considerable variation in their virulence in this model when virulence was measured as release of(More)
