Antisense oligonucleotides (AONs) are promising candidates for treatment of Duchenne muscular dystrophy (DMD), a severe and progressive disease resulting in premature death. However, more knowledge on the pharmacokinetics of new AON drug candidates is desired for effective application in the clinic. We assessed the feasibility of using...

Positron emission tomography (PET) imaging of P-glycoprotein (P-gp) in the blood-brain barrier can be important in neurological diseases where P-gp is affected, such as Alzheimer’s disease. Radiotracers used in the imaging studies are present at very small, nanomolar, concentration, whereas in vitro assays where these tracers are characterized,...

Background: Worldwide obesity has nearly doubled since 1980 and is a leading risk for global deaths, profoundly affecting morbidity, mortality, health-care costs, and professional and personal quality of life. Treatment of obesity and its consequences include lifestyle intervention, pharmacotherapy, and bariatric surgery. Polyglucosamines have...

Aims The aims of the study were to compare [14C]-paracetamol ([14C]-PARA) paediatric pharmacokinetics (PK) after administration mixed in a therapeutic dose or an isolated microdose and to develop further and validate accelerator mass spectrometry (AMS) bioanalysis in the 0-2 year old age group. Methods [14C]-PARA concentrations in 10-15 μl...

Immunogenicity is a major issue of concern for monoclonal antibodies used in human diseases and is by default mainly determined in non-human primates (NHP), as target molecules are considered most similar in NHP compared to human. In this manuscript the predictive value of immunogenicity testing in minipigs for human safety is evaluated, as the...

Insulin signaling in the central nervous system (CNS) is required for the inhibitory effect of insulin on glucose production. Our aim was to determine whether the CNS is also involved in the stimulatory effect of circulating insulin on the tissue-specific retention of fatty acid (FA) from plasma. In wild-type mice, hyperinsulinemic-euglycemic...

This review summarises the most recent developments in ginseng analysis, in particular the novel approaches in sample pre-treatment and the use of high-performance liquid-chromatography-mass spectrometry. The review also presents novel data on analysing ginseng extracts by nuclear magnetic resonance spectroscopy and high-resolution mass...

CIA in the rhesus monkey is an autoimmune-based polyarthritis with inflammation and erosion of synovial joints that shares various features with human rheumatoid arthritis (RA). The close phylogenetic relationship between man and rhesus monkey makes the model very suitable for preclinical safety and efficacy testing of new therapeutics with...

The pharmacokinetics of cisplatin was investigated in 13 patients receiving 18 courses of cisplatin alone or in combination with amifostine to investigate the influence of amifostine (WR 2721; Ethyol) on the pharmacokinetics of cisplatin. Cisplatin was administered as a 1-h i.v. infusion, whereas amifostine was given i.v. over 15 min just before...

The objective of this study was to compare the bioavailability of s.c. and i.m. administration of human chorionic gonadotrophin (HCG; Pregnyl®). In a randomized, single centre, three-way cross-over study, 18 healthy pituitary-suppressed volunteers were assigned to single HCG injections of 5000 and 10000 IU i.m. and 10000 IU s.c. Rate (C(max), t...

We showed previously that amifostine (WR 2721; Ethyol), a protector against carboplatin-induced toxicities, changed the pharmacokinetics of carboplatin in tumor-bearing nude mice. In the present study, the influence of amifostine on the pharmacokinetics of carboplatin was studied in patients when carboplatin was given in combination with three...

The novel antidepressant mirtazapine is a racemate with both noradrenergic and serotonergic potentiating effects. In vitro metabolism of racemic mirtazapine was studied in (a) microsomes from cells expressing different cytochrome P450 (CYP) enzymes and (b) human liver microsomes from 10 subjects and compared with the rate of metabolism of 4...

BM 06.022 is a non-glycosylated mutant of human tissue-type plasminogen activator (t-PA) comprising only the kringle-2 and proteinase domains. The in vivo half-life of BM 06.022 antigen is 4- to 5-fold longer than that of t-PA antigen. The in vitro half-life of the activity of BM 06.022 at therapeutic concentrations in plasma is shorter than...

The toxicokinetics of the four stereoisomers of C(??)P(??)-soman were investigated in anesthetized, atropinized, and artificially ventilated rats at iv doses of 6 (495 ??g/kg) and 3 LD50. By integration of a thermodesorption/cold trap injector into our GLC analysis, the soman stereoisomers could be followed in rat blood down to a minimum...
