Given the relevance of vitamin D in calcium metabolism homeostatic control, as well as its role as differentiation and cell proliferation modulator, it is important to study its circulating level in patients considered at risk, in order to develop prevention strategies. We studied 77 postmenopausal women with no history of osteoactive drug therapy, corticosteroid intake or diseases that could a...

for assessment and comparison of measuring density methods of festuca ovina, bromus tomentellus and prangos ferulacea, three plants communities are selected. in all of plant community, reference area was defined and samples 7000 (70*100) square meter was selected. whole the area, sampling was accumplished as systematic-random. in each area, 5 transect 100 meter are established. then in areas 70...

introdouction: the purpose of the present study was to determine the possible relationship between gonial angle size and three mandibular morphometric parameters, namely, panoramic mandibular index (pmi), mandibular cortical width (mcw), and antegonial notch depth (ad), in digital panoramic radiographs. materials and methods: pmi, mcw, and ad were calculated in digital panoramic radiographs of ...

BACKGROUND AND AIMS Physical activity is important for muscle and bone strength in the growing child and may be impaired in paediatric patients with inflammatory bowel disease (IBD) even during quiescent disease. The SenseWearPro(2) armband allows to measure physical activity under everyday life conditions. METHODS Thirty-nine IBD patients (27 Crohn's disease, 12 ulcerative colitis, 24 boys) ...

OBJECTIVES To evaluate and compare anterior segment changes in patients taking alpha-1 (α1) blockers (tamsulosin, terazosin, doxazosin, alfuzosin) for benign prostatic hypertrophy, during drug intake and drug-free period, using ultrasound biomicroscopy (UBM). MATERIALS AND METHODS In this prospective study, UBM was done before and after pupil dilatation in 31 phakic eyes of 19 male patients t...

this paper discusses the arching effect as the formation of a stable arch in granular materials. for this aim, a developed trapdoor apparatus is designed in order to investigate the arch dimensions in term of the internal friction angle, average size and base angle of materials. observations show that for all tested granular ensembles, width and height of the arch increase with an increase in t...

in this study, we investigated variations of the angle between neck and shaft of femur after amputation of tigh above the knee. in amputated tigh the angle between neck and shaft of the femur is decreased than normal (nearly 90° degrees) (coax vara). the angle of the normal femur usually increases due to weight bearing (coax valga). in the patients that both tighs have been amputated the change...

Background: Scoliosis is the most common type of spinal deformity. A universal and standard method for evaluating scoliosis is Cobb angle measurement, but several studies have shown that there is intra- and inter- observer variation in measuring cobb angle manually.Objective: Develop a computer- assisted system to decrease operator-dependent errors in Cobb angle measurement.Methods: The spinal ...

METHOD Population based prevalence survey in rural West Bengal. People aged > or =50 years in randomly selected villages in 24 Parganas South district. The main outcome measures were dia...

This study investigated whether migraine influences the risk of primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) in Taiwan.We retrieved the data analyzed in this study from the National Health Insurance Research Database in Taiwan. We included 17,606 newly diagnosed migraine patients without preexisting glaucoma and randomly selected and matched 70,423 subjects witho...
