Moderate-altitude living (2,500 m), combined with low-altitude training (1,250 m) (i.e., live high-train low), results in a significantly greater improvement in maximal O2 uptake (V(02)max) and performance over equivalent sea-level training. Although the mean improvement in group response with this "high-low" training model is clear, the individual response displays a wide variability. To deter...
BACKGROUND Gonadotrophins are used in many assisted reproduction units to achieve a better success rate by increasing the number of replaced embryos. However, high oestradiol concentrations are associated with altered physiological functions and its complications. We investigated whether high oestradiol concentrations (> or =20 000 pmol/l) after ovarian stimulation in infertile women would affe...
BACKGROUND The counselling of poor ovarian responders about the probability of pregnancy remains a puzzle for gynaecologists. The aim of this study was to optimise the management of poor responders by investigating the role of the oocyte-derived factor bone morphogenetic protein-15 (BMP-15) combined with chronological age in the prediction of the outcome of in-vitro fertilisation-embryo transfe...
BACKGROUND Some patients with long-standing low back pain will benefit from treatment with strong opioids. However, it would be helpful to predict which patients will have a good response. A fixed-term opioid trial has been recommended, but there is little evidence to suggest how long this trial should be. We assessed data from a large-scale randomized comparison of transdermal fentanyl (TDF) a...
Approximately 5-10% of individuals, who are vaccinated with a hepatitis B (HB) vaccine designed based on the HBV genotype C, fail to acquire protective levels of antibodies. Here, host genetic factors behind low immune response to this HB vaccine were investigated by a genome wide association study (GWAS) and HLA association tests. A GWAS and HLA association tests were carried out using a total...
This study aimed to examine whether morphological changes during the early stage of treatment or indices of proliferation, apoptosis, or hormone receptors are reliable predictors of the hormonal response to uterus-preserving high-dose progestin therapy in patients with endometrial adenocarcinoma. Seven patients (5 good responders and 2 poor responders) with presumptive stage IA endometrial aden...
BACKGROUND Patients with non-ischemic heart failure etiology and left bundle branch block (LBBB) show better response to cardiac resynchronization therapy (CRT). While these patients have the most pronounced left ventricular (LV) dyssynchrony, LV dyssynchrony assessment often fails to predict outcome. We hypothesized that patients with favorable outcome from CRT can be identified by a character...
Background and Aims: Hepatitis C virus (HCV) can cause hepatocellular carcinoma (HCC) in a significant proportion (≈ 20 %) of individuals with chronic HCV infection (CHC). Currently, CHC is treated with peginterferon and ribavirin, which depending on genotype approximately 50 to 70% of patients are cured. The so-called “extrahepatic HCV infection” or viral replication in regio...
