We could identify the MPTP-like compound and isoquinoline derivative N-methyl-norsalsolinol (2-MDTIQ) in cerebrospinal fluid (CSF) of patients with Parkinson's disease. The presence of 2-MDTIQ negatively correlated with the disease duration. In order to study the relationship between presence of 2-MDTIQ

Most staphylococci produce short α-type PSMs and about twice as long β-type PSMs that are potent leukocyte attractants and toxins. PSMs are usually secreted with the N-terminal formyl group but are only weak agonists for the leukocyte FPR1. Instead, the

Markers of oxidative stress are increased in cerebrospinal fluid (CSF) of patients with Alzheimer disease (AD), although none of those reported are appropriate diagnostic markers because of the overlap between patients with AD and control subjects. To determine the ratio

The electrical activity in developing and mature neurons determines the intracellular calcium concentration ([Ca(2+)]i), which in turn is translated into biochemical activities through various signaling cascades. Electrical activity is under control of neuromodulators, which can alter neuronal responses to incoming
