Limitations of maximal oxygen uptake during whole-body exercise
(2007-10-26)
Oxygen uptake increases linearly with increased running speed or rate of
work and finally reaches a maximum beyond which no effort can drive it
further. This phenomenon is referred to as the plateau in oxygen
uptake . ...
Modulation of acetylcholine release by serotonergic 5-HT1A and 5-HT1B receptors : a microdialysis study in the awake rat
(2007-05-25)
The aim of the thesis was to investigate the effects of the 5-HT1A
receptor antagonist robalzotan (NAD-299) and the 5-HT1B receptor
antagonist NAS-181 ((R)-(+)-2-(3-morpholinomethyl-2Hchromen-8-yl)
oxymethyl-morpholine methanesulfonate...
Analytical and pharmacological studies of cyclophosphamide
(2008-03-17)
-liquid extraction (LLE) and analyzed using liquid chromatography with UV detection (LC-UV). The limit of detection (LOD) was 0.005 μg/mL and the limit of quantification was 0.5 μg/mL for LC-MS/MS. The accuracy of the quality control (QC) samples ranged from 91...
Strategies to increase effectiveness of growth factor receptors-targeted therapy in glioblastoma
(2007-11-14)
factor receptor tyrosine kinases
(GFR-TKs). In paper I, we showed that the pharmacologic inhibition (using
small molecule inhibitors) of IGF-1R, PDGFR and their intracellular
signalling via PI3-K and ERK1/2 kinases had only modest or not antitumour...
Tonsillar cancer : incidence, prevalence of HPV and survival
(2008-04-04)
Since human papilloma virus (HPV) in the mid 1980ies was first observed
in squamous cell carcinoma of the head and neck, its role and impact,
especially on oral and oropharyngeal cancer, have attracted extensive
interest. ...
Induction of human cytochrome P450 enzymes : predictive in vitro models and rifampicin induction in vivo
(2008-01-24)
The cytochrome P450 (P450) enzymes comprise the most important enzyme
system with regard to phase I metabolism of drugs. Induction of P450s can
result in decreased plasma concentrations of the drug itself or a
coadminstered ...
Autocrine and paracrine regulation of Leydig cell survival in the postnatal testis
(2007-09-07)
by immature rats Leydig cells., (ii) possible antiapoptotic effects of IGF-I during testicular development and the role played by IGF-1R in this context; (iii) the influence of IGFBP-3 on apoptosis and steroidogenesis in rat Leydig cells in relation...
Microfluidic electrocapture in proteomic sample preparation for mass spectrometry
(2007-10-19)
Proteomics is a technology-driven discipline and very labor-intensive.
Over the last couple of years, methods with microfluidic systems have
been used to simplify analytical procedures via integration of laboratory
processes ...
Studies on human sterol 27-hydroxylase with emphasis on its mechanism of regulation and metabolic consequences of a deficient enzyme
(2007-05-11)
Sterol 27-hydroxylase (CYP27A1) is a mitochondrial cytochrome P-450
enzyme present in most animal cells. In hepatocytes, CYP27A1 has an
important role in connection with biosynthesis of bile acids from
cholesterol. In ...
Long-term tracheostomy : outcome, cannula care, and material wear
(2007-09-21)
Do people with long-term tracheostomy need hospital care? Which cleaning
method is most appropriate for decontamination of inner cannulae? Are
tracheostomy tubes changed for rational reasons? There is clearly a lack
of ...
