This study compared intake of vitamins and antioxidant nutritional status of smokers and nonsmokers, and the effect of supplementation of vitamin C and vitamin E on antioxidant system of smokers and nonsmokers. Subjects were 30 smokers and 30 non-smokers of male university students. They were divided into groups of 10 subjects each one with supplementation for 4 weeks, to investigate the effects of supplementation. Smokers were divided into vitamin C supplement group, vitamin E supplement group and vitamin C and vitamin E combination supplement group, and so were nonsmokers. The supplementation of vitamin C was 500mg and vitamin E was 400IU. There was no significant difference of antioxidant vitamin intakes between smokers and non-smokers, and plasma concentration of vitamin C in smokers was lower than non-smokers (p<0.05). Blood pressure was higher in smokers (p<0.05), with no difference in blood glucose levels, methemoglobin and TBARS, but SOD activity was significantly higher in non-smokers (p<0.001). Vitamin C supplementation resulted in a significant decrease of diastolic blood pressure (p<0.01), systolic blood pressure (p<0.001) and methemoglobin (p<0.001) in smokers. Also a significant decrease of diastolic blood pressure (p<0.05), systolic blood pressure (p<0.05), blood glucose (p<0.05), methemoglobin (p<0.001) and TBARS (p<0.05), with significant increase of SOD activity (p<0.001) were found in vitamin E supplement group. In vitamin C and vitamin E combination supplement group, there was a significant decrease of diastolic blood pressure (p<0.05), methemoglobin (p<0.01) and TBARS (p<0.05). In non-smokers, methemoglobins (p<0.001) of vitamin C supplement group and vitamin E supplement group decreased, and diastolic pressure (p<0.05), methemoglobin (p<0.01) and TBARS (p<0.05) significantly decreased in vitamin C and vitamin E combination supplement group. These results indicated better efficacy of antioxidant supplementation in smokers than in nonsmokers, suggesting that the supplementation of vitamin C and vitamin E might decrease the oxidative stress and various risk factors of smoking-related diseases.

Certain pre-transfusion tests are not commonly performed during emergency blood transfusion. In this study, we reviewed and analyzed the data of post-blood transfusion antibody screening tests to establish the effects of unexpected antibodies causing hemolytic transfusion reactions. We reviewed information published domestically and internationally, and selected the data of 68,602 antibody screening tests and 528 antibody identification tests conducted at P hospital. We found that unexpected antibody positive (1198,1.74%), Rh type (161, 30.49%), Lewis type (67, 12.69%), others (Di (a), 28, 5.30%). The anti-E type positive was 93 (17.61%), and that of the cases with anti-C (13, 2.46%). Only data of domestic cases were included for analysis that were published before 2007, which established the presence of antibodies of the following types and numbers of cases: anti-E (196, 22.45%), anti-Le a (82, 9.39%), and anti-E+C (60, 6.87%). In 2018, anti-E (107, 17.12%), anti-E+Canti-E+C (56, 8.96%), and anti-Di a (28, 4.48%) were detected. In other domestic cases, S hospital was detect to anti-E, anti-Le a, anti-E+C. The Anti-E, anti-D, anti-E+C, and anti-C+E were detected in D hospital. In Saudi Arabia, Anti-D, anti-E, and anti-Jka was detected. The Anti-M, Anti-N, Anti-Le (a), and Anti-D were detected in India. Requests for emergency blood transfusion increased 1.8 times after the opening of the trauma center. This study has the disadvantage of being a cross-sectional study. additional studies are needed to provide basic information on alternative treatments that can increase the safety and reduce the side effects of hemolytic transfusion in emergency transfusion situations.

This paper describes the influence of the electrode materials, moisture content, electrolyte density, temperature, surface state, ion absorbent on the C.T.I of phenolic resin by the I.E,C, 112 method. C.T.I are increased for electrode materials with low hydrogen overvoltage and high soluble point. Increusing moisture content of samples increased by logarithmical on the droplet number to tracking breakdown. Increasing electrolyte temperature region above 70-80(.deg.C) decreased hydrogen over-voltage, following the density changes are decreased by C.T.I=1/aD$^{2}$-bD+C.

Graph C*-algebras C*(E) are the universal C*-algebras generated by partial isometries satisfying the Cuntz-Krieger relations determined by directed graphs E, and it is known that a simple graph C*-algebra is extremally rich in sense that it contains enough extreme consider a sufficient condition on a graph for which the associated graph algebra(possibly nonsimple) is extremally rich. We also present examples of nonextremally rich prime graph C*-algebras with finitely many ideals and with real rank zero.

CYP2E1 PstI polymorphism G-1259C (rs3813867) genotype distributions vary significantly among different populations and are associated with both diseases, like cancer, and adverse drug effects. To date, there have been limited genotype distributions and allele frequencies of this polymorphism reported in the three major indigenous ethnic groups (KadazanDusun, Bajau, and Rungus) in Sabah, also known as North Borneo. The aim of this study was to investigate the genotype distributions and allele frequencies of the CYP2E1 PstI polymorphism G-1259C in these three major indigenous peoples in Sabah. A total of 640 healthy individuals from the three dominant indigenous groups were recruited for this study. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) at G-1259C polymorphic site of CYP2E1 gene was performed using the Pst I restriction enzyme. Fragments were analyzed using agarose gel electrophoresis and confirmed by direct sequencing. Overall, the allele frequencies were 90.3% for c1 allele and 9.7% for c2 allele. The genotype frequencies for c1/c1, c1/c2 and c2/c2 were observed as 80.9%, 18.8%, and 0.3%, respectively. A highly statistical significant difference (p<0.001) was observed in the genotype distributions between indigenous groups in Sabah with all Asian and non-Asian populations. However, among these three indigenous groups, there was no statistical significant difference (p>0.001) in their genotype distributions. The three major indigenous ethnic groups in Sabah show unique genotype distributions when compared with other populations. This finding indicates the importance of establishing the genotype distributions of CYP2E1 PstI polymorphism in the indigenous populations.
