Metabolic diseases or injuries damage bone structure and self-renewal capacity. Trace elements and hydroxyapatite crystals are important in the development of biomaterials to support the renewal of bone extracellular matrix. In this study, it was assumed that the boron-loaded nanometer-sized hydroxyapatite composite supports the construction of extracellular matrix by controlled boron release in order to prevent its toxic effect. In this context, boron release from nanometer-sized hydroxyapatite was calculated by ICP-MS as in large proportion within 1 h and continuing release was provided at a constant low dose. The effect of the boron-containing nanometer-sized hydroxyapatite composite on the proliferation of SaOS-2 osteoblasts and human bone marrow-derived mesenchymal stem cells was evaluated by WST-1 and compared with the effects of nano-hydroxyapatite and boric acid. Boron increased proliferation of mesenchymal stem cells at high doses and exhibited different effects on osteoblastic cell proliferation. Boron-containing nano-hydroxyapatite composites increased osteogenic differentiation of mesenchymal stem cells by increasing alkaline phosphatase activity, when compared to nano-hydroxyapatite composite and boric acid. The molecular mechanism of effective dose of boron-containing hydroxyapatite has been assessed by transcriptomic analysis and shown to affect genes involved in Wnt, TGF-beta, and response to stress signaling pathways when compared to nano-hydroxyapatite composite and boric acid. Finally, a safe osteoconductive dose range of boron-containing nano-hydroxyapatite composites for local repair of bone injuries and the molecular effect profile in the effective dose should be determined by further studies to validation of the regenerative therapeutic effect window.

Dietary selenium- and vitamin E-induced alterations in some rabbit tissues Turan, B; Zaloglu, N; Koc, E; Saran, Y; Akkas, N (Springer Science and Business Media LLC, 1997-09-01) The present study was designed to investigate and compare the effects of dietary selenium (Se) and vitamin E on some physiological parameters and histological changes in liver, heart, and skin tissues, as well as the blood parameters and the related enzymes. Both sex young rabbits were fed with deficient (9.8 mu g/kg diet), adequate (225 mu g/kg diet), and rich (4.2 mg/kg diet) Se and vitamin E diets for 12-15 wk for this purpose As the plasma Se levels and the erythrocyte glutathione (GSH) peroxidase activ...
STUDIES ON METAL RESISTANCE SYSTEM IN KLUYVEROMYCES-MARXIANUS YAZGAN, A; Özcengiz, Gülay; ALAEDDINOGLU, NG (Springer Science and Business Media LLC, 1993-08-01) Through preliminary plate tests, Kluyveromyces marxianus was found to be much more resistant to toxic heavy metals compared to a CUP1R strain of Saccharomyces cerevisiae. Specific growth rate and maximum dry weights affected by increasing metal concentrations were determined to obtain precise patterns of resistance. Metal biosorption was also monitored during the course of growth in synthetic media containing respective metals at 0.5 mM final concentration. Although Zn- and Co-binding was negligible, as muc...
The effects of selenium on stz-induced diabetic rat kidney plasma membrane Gurbanov, Rafig; Severcan, Feride; Department of Biochemistry (2010) The kidney is one of the most affected organs of body from diabetes. Diabetic kidney disease is a complication of diabetes seen in 30-40% of diabetic person. The aim of this work is to contribute the useful information in the therapy of diabetes. It is very important to know the role of antioxidants at the molecular level during diabetes. The protecting role of antioxidants against lipid peroxidation, the effect of cellular antioxidant enzyme systems, understanding the changes of membrane fluidity, lipid or...
The serum immunoglobulin G glycosylation signature of gastric cancer Ruhaak, L. Renee; Barkauskas, Donald A.; Torres, Javier; Cooke, Cara L.; Wu, Lauren D.; Stroble, Carol; Özcan Kabasakal, Süreyya; Williams, Cynthia C.; Camorlinga, Margarita; Rocke, David M.; Lebrilla, Carlito B.; Solnick, Jay V. (Elsevier BV, 2015-03-01) Biomarkers may facilitate detection of gastric cancer at an earlier stage and reduce mortality. Here we sought to determine if the glycosylation profile of serum immunoglobulin G (IgG) could distinguish patients with non-atrophic gastritis (NAG), duodenal ulcer (DU) and gastric cancer (GC). Serum IgG was released and analyzed using nano-LC–TOF mass spectrometry. Statistically significant false discovery rate (FDR)-adjusted p-values were observed for 18 glycans, eight that differed significantly between NAG ...
The expression of gst genes in diabetic rat liver tissues İrtem Kartal, Deniz; Güray, Tülin; Department of Biochemistry (2008) Free radicals which have critical roles in living systems through their beneficial and detrimental effects play an important role in medical revolution in health. Radicals are produced in the cells and tissues of our bodies by various processes and reactions. Diabetes mellitus is an extremely common disease in the world which seems to be accompanied by a shortage of antioxidants and an increase in free radicals, the end result of oxidative stress. Glutathione S-Transferases (GST; EC 2.5.1.18) are found in e...
