We evaluated the use of a newly described sodC-based real-time-polymerase chain reaction (RT-PCR) assay for detecting Neisseria meningitidis in normally sterile sites, such as cerebrospinal fluid and serum. The sodC-based RT-PCR assay has an advantage over ctrA for detecting nongroupable N. meningitidis isolates, which are commonly present in asymptomatic pharyngeal carriage. However, in our st...
The development and validation of biomarkers for the latent, prodromal and dementia stages of Alzheimer's disease (AD) is a pressing issue because of their high prevalence and an emerging set of experimental therapeutics that will soon force decisions regarding risk versus benefit. While genetic risk factors and neuroimaging will certainly have important roles to play, here we have focused on b...
Phosphorylation of tau protein is a critical event in the pathogenesis of Alzheimer's disease (AD). Increased phosphorylated tau and total tau levels, combined with reduced concentrations of amyloid-β 1-42 (Aβ42) in cerebrospinal fluid (CSF), but not in plasma or serum, have been generally accepted as sensitive AD diagnostic markers. However, obtaining CSF is a relatively invasive procedure tha...
During mammalian pregnancy, body temperature decreases and there are changes in fluid and electrolyte balance. Angiotensin signaling mechanisms in the brain have been shown to influence thermoregulation and body fluid balance in the nonpregnant state. We hypothesized that brain angiotensin is also implicated in adjusting these physiological systems in the pregnant rat. We compared core temperat...
Alzheimer's disease is a multifactorial and progressive neurodegenerative disease, extremely diffused and with an increasing prevalence worldwide. There is an urgent need for biomarkers to diagnose AD early in its course. Furthermore, accurate biomarkers would be able to determine the clinical efficacy of novel neuroprotective strategies. Although the heritability of late-onset AD is high, our ...
