UNLABELLED To understand age-related changes of whole-body and regional skeletal metabolism, it is important to investigate the mechanisms of age-related bone loss and to develop suitable treatments for it. Bone biopsies show metabolism of the particular site examined while biochemical markers for bone metabolism reflect total skeletal metabolism. Bone scintigraphy is a convenient and simple wa...

We have previously reported that most patients with esophagogastric cancer (EGC) undergoing potentially curative resections have bone marrow micrometastases (BMM). We present 10-year outcome data of patients with EGC whose rib marrow was examined for micrometastases and correlate the findings with treatment and conventional pathologic tumor staging. A total of 88 patients with localized esophag...

generation neural stem cells from neurosphere–derived bone marrow stem cells using bioactive substance atc. bone marrow cells (bmscs) were isolated from rat. bmscs cultured by dmem/f12 medium supplemented with 10% fetal bovine serum. these cells evaluated by specific markers of bmscs such as bioactive substance atc, b27. then bmscs differentionated in to neurosphere and divided in two groups wh...

BACKGROUND Bone metabolism disorders in hemodialysed patients (HD) involve several humoral factors, of which PTH plays the central role. Leptin is usually found increased in renal failure and its link with bone metabolism has not been elucidated. We investigated the BMD and bone metabolism in association with serum PTH, 25OHD3 and leptin in HD patients. METHODS We measured bone alkaline phosp...

objective: the aim of this study was to evaluate the effect of exendin-4 (ex-4) on differentiation of insulin-producing cells (ipcs) from rat bone marrow-derived mesenchymal stem cells (rat-bm-mscs). materials and methods: in this experimental study, rat-bm-mscs were cultured and the cells characterized by flow cytometry analysis of cell surface markers. rat-bm-mscs were subsequently treated wi...

Nutrition plays an important role in osteoporosis prevention and treatment. Substantial progress in both laboratory analyses and clinical use of biochemical markers has modified the strategy of anti-osteoporotic drug development. The present review examines the use of biochemical markers in clinical research aimed at characterising the influence of foods or nutrients on bone metabolism. The two...

Osteoclasts are large multinucleated cells responsible for bone resorption. Excessive inflammatory activation of osteoclasts leads to bony erosions, which are the hallmark of several diseases such as rheumatoid arthritis (RA). Salt-inducible kinases (SIK) constitute a subfamily of kinases comprising three members (SIK1, -2, and -3). Inhibition of SIK kinase activity induces an anti-inflammatory...

Bone is formed through the processes of endochondral and intramembranous ossification. In endochondral ossification primary mesenchymal cells differentiate to chondrocytes and then are progressively substituted by bone, while in intramembranous ossification mesenchymal stem cells (MSCs) differentiate directly into osteoblasts to form bone. The steps of osteogenic proliferation, differentiation,...
