root morphological and distribution responses of signal grass (brachiaria decumbens) to long-term cattle grazing were examined in a tropical pasture in malaysia. the treatments were no grazing by cattle and grazing at a moderate stocking density (2.7 animal unit/ha) under rotational grazing for 33 years. the method consists of taking soil core using a soil corer to a depth of 30 cm and extracti...

OBJECTIVE This study was conducted to compare the mandibular bone density between postmenopausal women with normal skeletal bone mass density (BMD) and those with low skeletal BMD using digital panoramic radiographs. MATERIALS AND METHODS One hundred fifteen postmenopausal women were divided into normal and osteoporotic/osteopenic groups. Digital panoramic radiographs were prepared using Digo...

background there is evidence in support of low bone density in young patients with disorders of phenylalanine metabolism; however, little is known about muscle and fat mass in these patients, especially in those with mild hyperphenylalaninemia (mhpa). objectives we aimed to evaluate body composition of children and adolescents with early-diagnosed disorders of phenylalanine metabolism. patients...

this study was undertaken to assess the frequency of decreased bone mineral density and its risk factors as well as its impact on the quality of life during childhood among hemophiliac patients. materials and methods: thirty seven children with severe hemophilia a and b, referred to mofid children’s hospital during 2010, were selected. for all patients the joint score, body mass indexes, bone m...

since mammography images are in low-contrast, applying enhancement techniques as a pre-processing step are wisely recommended in classification of the abnormal lesions into benign or malignant. a new kind of structural enhancement is proposed by morphological operator which introduces an optimal gaussian kernel primitive, the kernel parameters are optimized the use of genetic algorithm­­. we al...

Background: Total bone mass acquired during childhood is known to be the most important determinant and base of lifelong skeletal health. The present study investigated the prevalence of low bone mass for chronological age (LBM) in lumbar and femoral areas of leukemic children in the south of Iran and evaluated the association of anthropometric, clinical and laboratory data of these children ...
