This study aims to determine the effect of a single exhausting exercise on plasma PYY, NPY and IGF-1 in young athletes. Thirty-one young athletes (aged 19.52±2.75 years, body mass 79.24±16.13 kg, height 173±6.49 cm, and body fat 16.37±5.92%) volunteered to participate in this study. The participations, in randomized crossover manner, performed a single exercise bout on a cycle ergometer at 50...
Insulin-like growth factors (IGF) are potent neurotrophic and neurorepair that were recently proposed as biomarkers of traumatic brain injury (TBI) associated psychiatric comorbidities, in particular post-traumatic stress disorder (PSTD). We tested the hypothesis IGF system is differentially deregulated acute early chronic stages TBI, under stress. Plasma IGF1 IGF2 levels evaluated mice 3 weeks...
We investigate the relationship between brain extracellular fluid free phenytoin concentration and plasma free phenytoin concentration in adults with acute brain injury. Daily cerebral microdialysate free phenytoin concentration was measured in eight adults with acute brain injury and compared to simultaneous measurement of plasma free phenytoin concentration. The group data revealed no signifi...
Plasma and brain concentrations of the nicotinic acetylcholine receptor antagonist and blood-brain barrier choline transporter substrate, N,N'-dodecane-1,12-diyl-bis-3-picolinium dibromide (bPiDDB), were analyzed by liquid beta-scintillation spectrometry after administration of [14CH3]bPiDDB to male Sprague-Dawley rats. Plasma concentrations of [14CH3]bPiDDB were determined at 10 time points ov...
background: prostate specific antigen (psa) is an important laboratory marker for diagnosis of prostatic cancer. thus, development of diagnostic tools specific for psa plays an important role in screening, monitoring and early diagnosis of prostate cancer. in this paper, the production and characterization of a panel of murine monoclonal antibodies (mabs) against psa have been presented. metho...
it has been hypothesized that elevated plasma homocysteine (hcy) plays a role in the pathogenesis of alzheimer’s disease (ad) and age-related cognitive decline. the mechanism of hcy neurotoxicity in the brain is controversial as well hcy is a ligand of nmda receptor. memantine, an uncompetitive antagonist of n-methyl-d-aspartate (nmda) receptors approved for the treatment of moderate to severe ...
In view of reports of colistin-induced neurotoxicity in infected patients, the aim of this study was to assess whether the integrity of the blood-brain barrier (BBB) and the brain uptake of colistin are altered in the presence of systemic Pseudomonas aeruginosa infection. Bacteremia was confirmed 8 h after intramuscular administration of P. aeruginosa ATCC 27853 to Swiss Outbred mice, at which ...
Cell-free circulating tumour DNA (ctDNA) in plasma has been shown to be informative of the genomic alterations present in tumours and has been used to monitor tumour progression and response to treatments. However, patients with brain tumours do not present with or present with low amounts of ctDNA in plasma precluding the genomic characterization of brain cancer through plasma ctDNA. Here we s...
objective(s): it is difficult to investigate the whole-body distribution of an orally administered drug by means of positron emission tomography (pet), owing to the short physical half-life of radionuclides, especially when 11c-labeled compounds are tested. therefore, we aimed to examine the whole-body distribution of donepezil (dnp) as an acetylcholinesterase inhibitor by means of 11c-dnp pet ...
Background & Objectives: Lifestyle modification through healthy diets and sufficient physical activity plays a pivotal role in the improvement of overall health. This study aimed to evaluate the effects of a single session of concurrent exercise on the plasma levels of peptide YY (PYY) and neuropeptide Y (NPY) in obese young men. Material and Methods: In total, 24 obese young men with mean a...
