Background/Aims Methylation status plays a causal role in carcinogenesis in targeted tissues. However, the relationship between the DNA methylation status of multiple genes in blood leukocytes and colorectal cancer (CRC) susceptibility as well as interactions between dietary factors and CRC risks are unclear. Methods We performed a case-control study with 466 CRC patients and 507 cancer-free ...

Results The changes of FT-IR spectraat 1743 cmresulted from hyperoxidation of lipids due to oxidative stress. The characteristic bands at the spectral regions 1200-900 cm and 700-400 cmshowed the formation of low crystallinity biological hydroxyapatite (Ca10(PO4)6(OH)2) and calcium monophosphate (CaHPO4) salts. The results were confirmed using SEM-ΕDAX and XRD analysis. The observed cross-linki...

treatment (1). But, local implantable delivery with sustained antibiotic release may offer considerable advantages over the traditional method of therapy by producing an effective local antibiotic concentration at the diseased site, with the limitation of systemic exposure to antibiotics maintaining low systemic side effects (2). Hydroxyapatite (HAp, [Ca10(PO4)6(OH)2]) is one of the widely used...

In the present work, effectiveness of vacuum deposition technique for obtaining composite thin films based on chitosan-coated magnesium-doped hydroxyapatite Ca10?xMgx(PO4)6 (OH)2 with xMg = 0.025 (MgHApCh) was proved first time. The prepared samples were exposed to three doses (0, 3, and 6 Gy) gamma irradiation. MgHApCh nonirradiated irradiated evaluated by scanning electron microscopy (SEM), a...

The purpose of the study was development water-resistant catalyst and catalytic processes for conversion hydrous ethanol to 1-butanol. Water, in ethanol, strongly inhibits 1-butanol on solid catalysts. In this study, nonstoichiometric P-deficient hydroxyapatite containing carbonate anions (C-HAP), Ca10−x/2(PO4)6−x(CO3)x(OH)2, displayed good performance Guerbet condensation hydrated 1-butanol, a...

In this work, Fourier Transform Infrared spectroscopy (FT-IR) analysis were conducted on europium doped hydroxyapatite, Ca10-xEux(PO4)6(OH)2 nanocrystalline powders (Eu:HAp) with 0 ≤ xEu ≤ 0.2. Antimicrobial studies were also performed for the first time on Eu:Hap. The antimicrobial properties of Eu:HAp nanoparticles with 0 ≤ xEu ≤ 0.2 on Gram-negative (E coli ATCC 25922, Pseudomonas aeruginosa...
