In adult bone, vitamin K contributes to bone health, probably through its role as co-factor in the carboxylation of osteocalcin. In children, the significance of vitamin K in bone-mass acquisition is less well known. The objective of this longitudinal study was to determine whether biochemical indicators of vitamin K status are related to (gains in) bone mineral content (BMC) and markers of bon...

Objective: To evaluate stromal cells of the bone marrow microenvironment (BMM) in bone marrow trephine biopsy (BMTB) specimens, with a focus on fibronectin, tumor necrosis factor- alpha (TNF-α) and L-selectin in Non- Hodgkin’s lymphoma (NHL) patients, before and after therapy. Materials and Methods: A total of 80 de novo NHL patients, 64 with B-cell lymphomas 80% , (follicular cell lymphoma (FC...

Men with androgen-independent prostate cancer (AIPC) frequently have bone metastasis. The effects of chemotherapy on markers of bone metabolism have not been well characterized. We conducted a prospective study of patients with AIPC randomized in the first cycle to receive either docetaxel/estramustine or zoledronic acid, a bisphosphonate, to inhibit osteoclastic activity. Here we report the ef...

Introduction: The aim of this research was to study the effect of a 6-week supplemented diet on increasing bone density by measuring calcium, phosphorus and bone mineral density (BMD) in male rats. Materials and methods: In this experimental study, 24 Wistar male rats, aged between 15 and 20 days, were selected. The rats were randomly divided into 3 groups: immune system supplement (ISS), ...

Colony-stimulating factor 1 (CSF-1) is required for the development of monocytes/macrophages from progenitor cells and for the survival and activation of mature macrophages. The receptor for CSF-1 is the product of the c-fms proto-oncogene, which, on binding ligand, can stimulate a mitogenic response in the appropriate cells. To investigate which genes are regulated in response to CSF-1-stimula...

[Purpose] This prospective longitudinal study evaluated the changes in bone metabolism markers and bone mineral density of spinal cord injury patients over 3 years. We also assessed the relationships among the bone mineral density, bone metabolism, and clinical data of spinal cord injury patients. [Subjects and Methods] We assessed the clinical data (i.e., immobilization due to surgery, neurolo...

Elderly patients often are unable to enjoy pain free physical activity due to various orthopedic problems. The orthopedic problems in the geriatric group comprises, bone disease due to metabolic conditions such as osteoporosis and osteomalacia, fractures peculiar to old age, degenerative disorders and metastatic bone disease. With the increase in life expectancy, osteoporosis has become a formi...
