Background: Postmenopausal onset rheumatoid arthritis (post-RA) is expected to have greater bone mineral density (BMD) loss than premenopauasal onset (pre-RA) due to estrogen deficiency and aging. This study aimed to compare the BMD status of the two RA groups with age-matched non-RA controls.   Methods: The patients with RA on follow-up examination were stratified according to age of onset. ...

INTRODUCTION People with rheumatoid arthritis (RA) frequently report reduced health-related quality of life (HRQoL), the impact one's health has on physical, emotional and social well-being. There are likely numerous causes for poor HRQoL, but people with RA have identified sleep disturbances as a key contributor to their well-being. This study will identify sleep/wake rhythm-associated paramet...

The development of generic skills and competences has become a central component contemporary engineering education due to increased societal occupational complexity. Problem- project-based learning (PBL) been highlighted as one the pedagogical approaches fostering that are transferable between various contexts. However, arguments linking PBL have mostly theoretically grounded or based on singu...

OBJECTIVE There is a consensus on the need for a more thorough assessment of outcome of RA from the perspective of those who experience the disease. Our objective was to assess the health- related quality of life (HR-QOL) of RA patients by the Nottingham Health Profile (NHP), the measurement of subjective experienced distress. METHODS One hundred and nineteen consecutive out-patients were cro...

Stem cells ensure tissue homeostasis through the production of differentiating and self-renewing progeny. In some tissues, this is achieved by the function of a definitive stem cell niche. However, the mechanisms that operate in mouse spermatogenesis are unknown because undifferentiated spermatogonia (Aundiff) are motile and intermingle with differentiating cells in an 'open' niche environment ...

introduction: dye removal from industrial wastewater has been considered as one of the most environmental issues. recently, new methods of treatment such as catalytic ozonation have been used to increase dye removal efficiency. so, the efficiency of catalytic ozonation by copper coated zeolite as a catalyst in the removal of reactive red 198 was investigated. materials & methods: in order to re...

During development of the vertebrate embryo neuronal differentiation and neural patterning take place progressively as the spinal cord is generated and the body axis elongates. Fibroblast Growth Factor (FGF) signalling maintains the undifferentiated cell state of axial progenitor cells in the stem zone/tailbud. As cells leave this region they encounter retinoic acid (RA), provided by the segmen...
