OBJECTIVES: Adiponectin is strongly associated with diabetes in the Western population. However, whether adiponectin is independently associated with impaired fasting glucose (IFG) in the non-obese population is unknown. METHODS: The serum adiponectin, insulin resistance (IR), and waist circumference (WC) of 27,549 healthy Koreans were measured. Individuals were then classified into tertile groups by gender. IFG was defined as a fasting serum glucose of 100-125 mg/dL without diabetes. IR was calculated using the homeostasis model assessment of insulin resistance (HOMA-IR). The association of adiponectin and IFG was determined using logistic regression analysis. RESULTS: WC and adiponectin were associated with IFG in both men and women. However, the association of WC with IFG was attenuated in both men and women after adjustment for the HOMA-IR. Adiponectin was still associated with IFG after adjustment for and stratification by HOMA-IR in men and women. Strong combined associations of IR and adiponectin with IFG were observed in men and women. Multivariate adjusted odds ratios (ORs) (95% confidence interval [CI]) among those in the highest tertile of IR and the lowest tertile of adiponectin were 9.8 (7.96 to 12.07) for men and 24.1 (13.86 to 41.94) for women. CONCLUSION: These results suggest that adiponectin is strongly associated with IFG, and point to adiponectin as an additional diagnostic biomarker of IFG in the non-diabetic population.

<P><B>Abstract</B></P> <P>An extremely sensitive CO sensor based on novel hybrid SnO<SUB>2</SUB>–ZnO core–shell (C–S) nanowires (NWs) functionalized by Au nanoparticles (NPs) was synthesized. First, networked SnO<SUB>2</SUB> NWs were successfully prepared using the vapor–liquid–solid growth method on an electrode layer with special patterns. A ZnO shell was subsequently coated on the SnO<SUB>2</SUB> core using atomic layer deposition, and Au NPs were then attached onto the ZnO shell using γ-ray radiolysis. The resulting sensor exhibited a very high response of 26.6–100ppb CO gas. Furthermore, the responses to other gases such as C<SUB>6</SUB>H<SUB>6</SUB> and C<SUB>6</SUB>H<SUB>7</SUB> were extremely low, indicating the very good selectivity of the sensor to CO gas. Besides acting as heterojunctions, the catalytic effect of the Au NPs on CO gas greatly improved the CO sensing capability of the Au-functionalized SnO<SUB>2</SUB>–ZnO C–S NWs. The high sensitivity and selectivity of this sensor can open a path for prompt toxic monitoring and early detection of fatal diseases related to CO.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Novel hybrid SnO<SUB>2</SUB>–ZnO core–shell nanowires functionalized by Au nanoparticles. </LI> <LI> The resulting sensor exhibited a very high response of 26.6–100ppb CO gas. </LI> <LI> The very good selectivity of the sensor to CO gas. </LI> <LI> Heterojunctions and the catalytic effect of Au greatly improved the CO sensing capability. </LI> </UL> </P>

<P><B>Abstract</B></P> <P>Although the employment of n-p heterojunctions is among the most popular strategies to increase the performance of gas sensors, there have been a few systematic studies to determine the optimal composition in n-p heterojunctions. This paper reports the results of a systematic study of (n) xSnO<SUB>2</SUB>-(p) (1-x) Co<SUB>3</SUB>O<SUB>4</SUB> composite nanofibers (NFs) for gas sensing applications. Composite NFs were synthesized by the electrospinning method followed by annealing at 600°C. For gas sensing studies, several gases at optimal working temperature (350°C) were tested. Depending on the nominal composition, the sensors showed either n-or p-type behavior as well as different responses to the target gases. Furthermore, for all gases tested, the 0·5SnO<SUB>2</SUB>-0·5Co<SUB>3</SUB>O<SUB>4</SUB> sensor (nominal composition) showed the best gas sensing characteristics. The underlying gas sensing mechanism was examined in detail. The highest response observed in the 0·5SnO<SUB>2</SUB>-0·5Co<SUB>3</SUB>O<SUB>4</SUB> NFs sensor was primarily attributed to the major role of the p-Co<SUB>3</SUB>O<SUB>4</SUB> nanograins as electron reservoir. In addition, the possible substitution of Co<SUP>+2</SUP>/Co<SUP>+3</SUP> in Sn<SUP>+4</SUP> sites, the catalytic effect of Co<SUB>3</SUB>O<SUB>4</SUB> and generation of defects were likely to be the secondary reasons. This highlights the importance of the optimal composition for achieving the maximum gas-sensing performance in n-p composite NFs.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Systematic study on SnO<SUB>2</SUB> (n) −Co<SUB>3</SUB>O<SUB>4</SUB> (p) electrospun composite NFs sensors. </LI> <LI> Transition from p-type to n-type semiconducting behavior by change of composition. </LI> <LI> Among various compositions, 0.5SnO<SUB>2</SUB>-0.5Co<SUB>3</SUB>O<SUB>4</SUB> showed the optimal composition. </LI> <LI> High response to low concentrations of C<SUB>6</SUB>H<SUB>6</SUB>. </LI> <LI> The main reasons for sensing enhancement were heterojunctions and catalytic effect. </LI> </UL> </P>

<P><B>Abstract</B></P> <P>Microwave (MW) irradiation has obtained extensive importance in the field of synthesis and treatment of nanoparticles, because of its faster, cleaner and cost effectiveness than the other conventional and wet chemical methods. In this study, ZnO/graphene nanocomposites were prepared and subsequently post-treated by MW irradiation. Responses of the MW irradiated ZnO/graphene nanocomposites sensors were tested towards various gases including NO<SUB>2</SUB>, ethanol, acetone, toluene and CO and the results were compared with those of pristine ZnO and ZnO/graphene sensors without MW irradiation. It was demonstrated that the MW irradiated sensor had much higher response particularly to NO<SUB>2</SUB> gas along with superior selectivity and shorter response/recovery times in comparison to unirradiated ZnO/graphene and pristine ZnO sensors. The possible underlying mechanism of this behavior is discussed in detail, mainly in terms of the MW-induced surface defects and the generation of finer ZnO nanoparticles. The results obtained demonstrated the beneficial effect of MW irradiation for enhancing the NO<SUB>2</SUB>-gas sensing behavior of ZnO/graphene nanocomposites, opening a new door not only to a novel synthesis of semiconductors/graphene nanocomposites, but also to a cost-effective way of improving their sensing capabilities.</P> <P><B>Highlights</B></P> <P> <UL> <LI> ZnO/graphene nanocomposites were prepared by microwave (MW) irradiation. </LI> <LI> MW irradiated sensor had much higher sensing performances particularly to NO<SUB>2</SUB> gas, in comparison to unirradiated ZnO/graphene and pristine ZnO sensors. </LI> <LI> The possible underlying mechanism is explained in terms of the MW-induced surface defects and the generation of finer ZnO nanoparticles. </LI> </UL> </P>

Soybean seeds are excellent sources of tocopherols, B vitamins, and isoflavones, which are well known for their health benefits. This study investigated the influence of environment and genotype on these constituents across 13 Korean soybean varieties cultivated in three locations during the 2017–2019 growing seasons. Statistical analyses, employing both univariate and multivariate methods, revealed significant impacts of genetic and environmental factors on the composition of tocopherols, B vitamins, and isoflavones. Through permutational univariate analysis of variance, the primary contributors to each measured component were identified. Genotype strongly influenced the levels of β- and δ-tocopherols, whereas the interaction between location and year predominantly affected α- and γ-tocopherols. Vitamin B1 content was predominantly determined by genotype, whereas B3 and B6 were influenced by annual variations. Vitamin B2 level was primarily affected by the interplay between environmental and genotypic effects. Genotype had a significant effect on isoflavone components, with the exception of daidzein. Furthermore, early maturing varieties and those with black seed coats exhibited low levels of isoflavone components and total isoflavones, suggesting a relationship between maturity group and seed coat color in isoflavone variation. These findings can be used as reference values for compositional equivalence assessment of genetically modified soybeans.
