External audit of the absorbed dose determination from radiotherapy machines is performed using Lithium fluoride (LiF) TLD-100. Optimal parameters needed to obtain highly accurate dosage from LiF powder was investigated, including the setup of the Harshaw 4000 reader. A linear correspondence between the thermoluminescent signal and the mass of the powder(More)
OBJECTIVE The aim of our study was to investigate the association of HLA-DRB1 and -DQB1 alleles with multiple sclerosis (MS) in a Tunisian population and their effect on age at onset and disease severity. METHODS 58 MS patients and 105 healthy controls were genotyped for HLA class II alleles by PCR-SSP technique. RESULTS An association of MS with(More)
Hypertrophic osteoarthropathy is a syndrome frequently described in intrathoracic diseases, especially malignant ones. The association with lung tuberculosis is rarely reported. The authors describe the case of a 35-year-old patient, a smoker, hospitalised for lung cavitation associated with hypertrophic osteoarthropathy. The assessment of the aetiology was(More)
Rheumatoid arthritis (RA) is an inflammatory disease, which affects synovial joints, and is influenced by environmental and genetic factors, in particular the human leucocyte antigen (HLA) system. In our study, we investigated the association of HLA class II DRB1 and DQB1 alleles and DRB1-DQB1 haplotypes with RA susceptibility in Tunisian subjects.(More)
AIM OF THE STUDY Platelet-activating factor interacts with its specific receptor and mediates leucocytes transmigration into central nervous system and expression of HLA molecules on antigens-presenting cells. These features are the major characteristics of multiple sclerosis pathology. In the present study, we investigated the role of platelet-activating(More)
OBJECTIVE This study investigated the association between HLA-DRB1 and -DQB1 alleles and DRB1-DQB1 haplotypes, and polycystic ovary syndrome (PCOS) in Bahraini women. DESIGN Case-control, retrospective study. METHODS Study subjects comprised 80 women with PCOS, and 169 age- and ethnically-matched control women. DRB1 and DQB1 genotyping was done by(More)
Chemokines and their receptors are known to mediate inflammation and tissue damage in autoimmune disorders such as multiple sclerosis (MS). Multiple sclerosis is an inflammatory disease of the central nervous system, characterized by myelin damage and neurological complications. Monocyte chemoattractant protein-1 (MCP-1) interacts with the C-C chemokine(More)
