Serum vitamin B12 and folate levels were determined by enzyme-linked immunosorbent assay. Plasma Hcy levels and MTHFR polymorphisms were determined by chemiluminescence and real time PCR methods, respectively. Mean serum vitamin B12 and Hcy levels were not significantly different while folic acid levels were significantly lower in the control group. There was no significant relationship
between disease activity and vitamin B12, folic acid and homocystein levels. No significant difference in C677T gene polymorphism was detected. Heterozygote A1298C gene polymorphism in the patient group was statistically higher than the control group. There was no significant relationship between MTHFR gene polymorphisms and vitamin B12, folic acid and homocysteine levels. In conclusion, vitamin B12, folate and Hcy levels are not altered in vitiligo and MTHFR gene mutations (C677T and A1298C) do not
seem to create selleck products Selleck OICR-9429 susceptibility for vitiligo.”
“Chronic kidney disease (CKD) is well known as a strong risk factor for both of end-stage renal disease and cardiovascular disease. To clarify the association of glucokinase and glucokinase regulatory protein (GCKR) polymorphisms with the risk of CKD in Japan, we examined this association among Japanese individuals using cross-sectional data.
The subjects for this analysis were 3,314 consecutively selected participants from the Japan Multi-Institutional Collaborative Cohort Study. Age- and sex- adjusted odds ratios (aORs) of CKD stages 3-5 were calculated for each genotype by logistic regression and the effects of genotype on estimated glomerular filtration
rate were evaluated by linear regression. Gene-environment check details interaction was also investigated based on questionnaire information.
When subjects with GCKR rs780094 G/A and G/G, or GCKR rs1260326 T/C and C/C were combined together and compared with the references (GCKR rs780094 A/A or GCKR rs1260326 T/T), the aORs were 0.84 (0.69-1.02) or 0.81 (0.67-0.99) (p = 0.075 or 0.037), respectively. A significant OR for interaction between GCKR rs1260326 T/T and current smoking (OR = 1.79, p = 0.041) was also observed.
The present study suggests a possible association of the T/T genotype of GCKR rs1260326 polymorphism with elevated risk of CKD and its interaction with current smoking, which may support the possibility of performing risk evaluation and prevention of this potentially life-threatening disease based on genetic traits in the near future.”
“In this work we demonstrate that high-energy electron beam irradiation (HEEBI) performed in air at room temperature affects remarkably the electrical, optical, and structural properties of undoped ZnO films prepared on SiO(2) substrates by magnetron sputtering techniques. Hall and photoluminescence measurements revealed that the p-type conductivity was realized in HEEBI treated films with low dose of 10(14) electrons/cm(2) and converted to n-type conductivity with further increase in the amount of dose.
