Utilization of biomass-derived materials or chemicals plays a significant role in reducing the dependence of unsustainable resources of petroleum and coal. A series of sulfonated glucose-derived solid acids(SGSAs) were developed in this study through a one-step method. These catalysts were characterized by XRD, FT-IR, SEM,and BET to determine their physiochemical properties, and their acid content was measured by acid–base titration. The catalytic performances of SGSA catalysts were evaluated in two esterification reactions: propionic acid or oleic acid with methanol(a typical reaction to upgrade biodiesel). Conversion of oleic acid and selectivity of methyl oleate can reach as high as 93.3% and 94.7% respectively over SGSA-6, which has the highest -SO3 H density. Moreover, regeneration of spent catalysts by sulfuric acid solution can significantly enhance their stability and reusability.

A novel silica catalyst was synthesized by evaporation-induced self-assembly （EISA） method and tested for the catalytic selective hydrolysis of cellulose to glucose. This silica catalyst exhibited a higher catalytic activity than other oxides prepared by the same method, such as ZrO2, TiO2, and Al2O3. Using silica as a catalyst, cellulose was selectively hydrolyzed into glucose with a glucose yield as high as 50% under hydrothermal conditions without hydrogen gas. The silica catalyst was characterized by Brunauer-Emmett-Teller （BET）, X-ray diffraction （XRD） and transmission electron microscopy （TEM）. The results of temperature-programmed desorption of ammonia （NH3-TPD） and textural properties indicated that the synergistic effect between strong acidity and a suitable pore diameter of the silica catalyst may be responsible for its high activity. In addition, the catalyst was recyclable and showed excellent stability during the recycle catalytic runs.

Oxidative stress is the key determinant in the pathogenesis of noise-induced hearing loss(NIHL). Given that cellular defense against oxidative stress is an energyconsuming process, the aim of the present study was to investigate whether increasing energy availability by glucose supplementation protects cochlear hair cells against oxidative stress and attenuates NIHL. Our results revealed that glucose supplementation reduced the noiseinduced formation of reactive oxygen species(ROS) and consequently attenuated noise-induced loss of outer hair cells, inner hair cell synaptic ribbons, and NIHL in CBA/J mice. In cochlear explants, glucose supplementation increased the levels of ATP and NADPH, as well as attenuating H_2O_2-induced ROS production and cytotoxicity. Moreover, pharmacological inhibition of glucose transporter type 1 activity abolished the protective effects of glucose against oxidative stress in HEI-OC1 cells. These findings suggest that energy availability is crucial for oxidative stress resistance and glucose supplementation offers a simple and effective approach for the protection of cochlear hair cells against oxidative stress and NIHL.

glucose is directly related to brain activity and to diabetes. Therefore, developing a rapid and sensitive method for glucose de- tection is essential. Here, label-free glucose detection at attomole levels was realized by detecting the average diameter change of gold nanoparticles （AuNPs） utilizing dynamic light scattering （DLS）. Single-strand DNA （ssDNA） adsorbed into the AuNPs＇ surfaces and prevented them from aggregating in solution that contained NaC1. However, ssDNA cleaved onto ssDNA fragments upon addition of glucose, and these fragments could not adsorb onto the AuNPs＇ surfaces. Therefore, in high-salt solution, AuNPs would aggregate and their average diameter would increase. Based on monitoring the average diameter of AuNPs with DLS, glucose could be detected in the range from 15 pmol/L to 2.0 nmol/L, with a detection limit of 8.3 pmol/L. Satisfactory results were also obtained when the proposed method was applied in human serum glucose detection.

glucose (Glu) is involved in not only plant physiological and developmental events but also plant responses to abiotic stresses. Here, we found that the exogenous Glu improved root and shoot growth, reduced shoot cadmium (Cd) concentration, and rescued Cd-induced chlorosis in Arabidopsis thaliana (Columbia ecotype, Col-0) under Cd stressed conditions. glucose increased Cd retained in the roots, thus reducing its translocation from root to shoot significantly. The most Cd retained in the roots was found in the hemicellulose 1. glucose combined with Cd (Glu t Cd) treatment did not affect the content of pectin and its binding capacity of Cd while it increased the content of hemicelluloses 1 and the amount of Cd retained in it significantly. Furthermore, Leadmium Green staining indicated that more Cd was compartmented into vacuoles in Glu t Cd treatment compared with Cd treatment alone, which was in accordance with the significant upregulation of the expression of tonoplast-localized metal transporter genes, suggesting that com-partmentation of Cd into vacuoles also contributes to the Glu-alleviated Cd toxicity. Taken together, we demonstrated that Glu-alleviated Cd toxicity is mediated through increas-ing Cd fixation in the root cell wall and sequestration into the vacuoles.
