PURPOSE Obesity has an etiology that is multidimensional in nature. Given the dearth of longitudinal data, we examined changes in adipose tissue (Ad) in relation to physical activity levels (PA), aerobic fitness (AF), and energy intake (EI) in Greek schoolchildren, as they progressed from age 12 to 14 yr. METHODS This was a 2-yr and three-time-point (TP)(More)
Polymerase chain reaction using specific primers, failed to detect HTLV-I amplicons in patients with rheumatic diseases previously shown to possess antibodies to retroviral products. However, by employing broad spectrum oligonucleotide primers, 135 bp amplicons were generated from peripheral blood mononuclear cells and synovial fluid cells. Subsequent(More)
Acid phosphatases (APs) are a family of enzymes that are widespread in nature, and can be found in many animal and plant species. Mystery surrounds the precise functional role of these molecular facilitators, despite much research. Yet, paradoxically, human APs have had considerable impact as tools of clinical investigation and intervention. One particular(More)
BACKGROUND In vitro the Epstein-Barr virus (EBV) encoded latent membrane protein 1 (LMP-1) has been shown to upregulate expression of matrix metalloproteinase 9 (MMP-9), a member of a family of zinc dependent endopeptidases that is believed to facilitate tumour invasion and metastasis by degradation of the extracellular matrix. AIM To test whether the(More)
Human Endogenous Retroviruses (HERVs) have been implicated in autoimmune and other diseases. Molecular mimicry has been postulated as a potential mechanism of autoimmunity. Exogenous viruses have also been reported to be associated with the same diseases, as have genetic and environmental factors. If molecular mimicry were to be shown to be an initiating(More)
Human endogenous retroviruses (HERVs) are a family of viruses within our genome with similarities to present day exogenous retroviruses. HERVs have been inherited by successive generations and it is possible that some have conferred biological benefits. However, several HERVs have been implicated in certain cancers and autoimmune diseases. This article(More)
Monoclonal antibodies are essential tools for many molecular immunology investigations. In particular, when used in combination with techniques such as epitope mapping and molecular modelling, monoclonal antibodies enable the antigenic profiling and visualisation of macromolecular surfaces. In addition, monoclonal antibodies have become key components in a(More)
Two monoclonal antibodies raised against human osteoclastoma were found to show antiosteoclastic activity on frozen sections of tumor. Immunoreactivity was localized on the membrane surface. These antibodies exhibited no activity against tissue macrophages and human visceral tissue except kidney, where they stained tubules but not glomeruli. In addition, no(More)
