since the waste of agricultural and horticultural products is high, appropriate methods should be used to produce products with high quality and shelf life for export. in iran a great part of fruits and vegetables are dried conventionally and farmer use so2 gas for preservation and color stability of dried apricots ,but this gas is allergic and carcinogenic and effort to find suitable substitut...
Background and Aim: Bone sialoprotein (BSP) is a specific marker of osteoblastic differentiation. In this research, the effect of Zoledronic Acid on BSP expression and methylation status during osteoblastic differentiation of mesenchymal stem cells (MSCs) was evaluated. Materials and Methods: In this experimental study, MSCs were isolated from human bone marrow. For osteogenic differentiation,...
PURPOSE In an effort to additionally determine the global patterns of CpG island hypermethylation in sporadic breast cancer, we searched for aberrant promoter methylation at 10 gene loci in 54 primary breast cancer and 10 breast benign lesions. EXPERIMENTAL DESIGN Genomic DNA sodium bisulfate converted from benign and malignant tissues was used as template in methyl-specific PCR for BRCA1, p1...
AIM The present case-control study was conducted to explore the association of MTHFR gene polymorphism and relations of P16, MGMT and HMLH1 to MTHFR and folate intake. METHODS A total of 257 cases of esophageal squamous cell carcinoma confirmed by histopathological examination were collected. Genotyping of P16, MGMT and HMLH1 was accomplished by methylation-specific polymerase chain reaction ...
Ammonia volatilization from poultry litter often causes high levels of atmospheric ammonia in poultry houses, which is detrimental to both farm workers and birds. Ammonia emissions from houses also aggravate environmental problems, such as acid rain, and result in a loss of fertilizer nitrogen. The objectives of this study were to determine the effect of litter amendments on ammonia volatilizat...
This study used the MG-63 osteosarcoma cell line to investigate the demethylation of the phosphate and tension homolog (PTEN) gene promoter and the change in PTEN gene expression levels, which are caused by the methylation inhibitor 5-azacytidine (5-Zac), and the association between the two. Different concentrations of 5-Zac (0, 5 and 10 μmol/l) were added into the MG-63 cell culture medium and...
An83-year-oldmanpresentedwith a recurrentmicronodular basal cell carcinoma located on the left lateral chest measuring 2.3 × 2.1 cm. His medical history was significant for coronary artery disease and the use combined clopidogrel bisulfate and aspirin antiplatelet therapy, which was maintained duringsurgery.Thetumorwasextirpatedwith6stagesofMohs micrographic surgery, producing a 10.5 × 8.9-cmde...
Electrochemical doping of bisulfate ions into single wall carbon nanotube (SWNT) bundles has been studied using coulometry, cyclic voltammetry, mass-uptake measurements, and Raman scattering experiments. A spontaneous charge-transfer reaction is observed prior to the application of an electrochemical driving force, in sharp contrast to previous observations in the graphite-H2SO4 system. A mass ...
