The aim of this study was to find a plasma biomarker, in relation with nitric oxide (NO), as a sign of brain damage severity following traumatic brain injury (TBI). We first investigated the post-traumatic evolution of the plasma concentrations of NO via the level of NO end-products metabolites
Previous studies have shown that severe sepsis after major trauma results in the reprioritization of release of hepatic acute-phase proteins (APP). They suggest competition for leucine for nutritional utilization may be responsible. To test this hypothesis, a branched-chain enriched (46.6%) amino
BACKGROUND
It is reported that psychiatric disorders, such as depression and schizophrenia, are associated with changes in serum activity of prolyl endopeptidase (EC 3.4.21.26), a cytosolic endopeptidase, which cleaves peptide bonds on the carboxylside of proline in proteins of relatively small
OBJECTIVE
Many neurochemical systems have been implicated in the development of Posttraumatic Stress Disorder (PTSD). The prolidase enzyme is a cytosolic exopeptidase that detaches proline or hydroxyproline from the carboxyl terminal position of dipeptides. Prolidase has important biological
This prospective study examined 44 patients with severe brain injury (33 survivors, 11 non-survivors), in order to clarify the question whether plasma amino acid deviations should definitively be considered detrimental or if this process might be part of a defense mechanism. Over an 8 day follow-up
The findings on the changes in amino acid metabolism and hormonal regulation after severe trauma and the conclusions draw from these are rather controversial. It is well documented that even small amounts of carbohydrates may significantly influence amino acid and carbohydrate metabolism especially
During post-traumatic regeneration of the polychaete annelid Owenia fusiformis, the extracellular matrix (ECM) formation was studied by light and electron microscopy and by histoautoradiography after incorporation of tritiated proline as marker for collagenic proteins. Three days after amputation, a
The paper describes pharmacological properties of the new nootropic drug noopept created using an original approach based on the imitation of a nonpeptide nootrope structure by means of the short-peptide design. In particular, the structure of pyracetam was designed using dipeptide nootropes.
Prolyl peptidases cleave proteins at proline residues and are of importance for cancer, neurological function, and type II diabetes. Prolyl endopeptidase (PEP) cleaves neuropeptides and is a drug target for neuropsychiatric diseases such as post-traumatic stress disorder, depression, and
