The volatile compounds of Jiaozi-steamed breads (JSBs) fermented by Jiaozi starters from eight regions in China were extracted using simultaneous distillation and extraction (SDE) and headspace solid-phase microextraction and determined using gas chromatography-mass spectrometry (GC-MS). 1-Hexanol, 3-methyl-1-butanol, phenylethyl alcohol, benzaldehyde, naphthalene, ethanol, acetic acid, and n-hexadecanoic acid were the main volatiles of JSBs. Principal component analysis exhibited that the volatiles of JSBs from Nanyang City, Xi’an City, and Zhumadian City was negatively correlated to that of other five JSB samples. Cluster analysis demonstrated that the volatile characteristics of JSBs from Heze City, Minqin County, Taian City, Weinan City, and Yuncheng City belonged to a category, and the JSBs of Nanyang City, Xi’an City, and Zhumadian City were different from other five JSBs. It demonstrated that the volatile components of steamed breads in North China and South China were different. Practical applications From this study, it can be seen that simultaneous distillation and extraction (SDE) can completely extract volatile compositions of steamed breads fermented by Chinese traditional starter Jiaozi. SDE/GC-MS was suitable for the analysis of JSBs volatile composition. The relative contents of 1-hexanol, 3-methyl-1-butanol, phenylethyl alcohol, benzaldehyde, naphthalene, ethanol, acetic acid, and n-hexadecanoic acid in JSBs were at high level, and their contents could be used as a marker to identify JSBs. The volatile compositions of JSBs made of Jiaozi starters from Heze City, Minqin County, Taian City, Weinan City, and Yuncheng City were similar. However, JSBs of Nanyang City, Xi’an City, and Zhumadian City were different from other five JSBs. The volatile components of steamed breads in North China and South China were different, which reflected the difference in dietary habit in the southern and northern areas of China.

Objective: To assess the antidiabetic effect of Opuntia dillenii seed oil on rats with diabetes mellitus. Methods: A rat diabetes model was established by intraperitoneal injection of rats with 50 mg/kg streptozotocin. Thirty albino Wistar rats were divided into five groups: the diabetic control group and normal control group were treated only with distilled water, two diabetic groups received 1 and 2 mL/kg of oil per day, respectively, for 30 days and one diabetic group received 2 mg/kg of glibenclamide. In addition, blood glucose was determined weekly. Body weight, average daily food, water intake and urinary volume of each animal were determined before and after the treatment period. After the treatment period, hepatic glycogen was determined using the anthrone reagent, and glycosuria, total cholesterol, triglycerides, alanine aminotransferase, aspartate aminotransferase, urea, creatinine and uric acid were estimated using common clinical diagnostic kits. Results: Oral intake of the oil at 1 and 2 mL/kg for the diabetic animals significantly diminished blood glucose, glycosuria, total cholesterol, triglycerides, alanine aminotransferase, aspartate aminotransferase, urea, creatinine and uric acid, accompanied by a noticeable elevation in the amount of hepatic glycogen in comparison with the diabetic control group. Similarly, Opuntia dillenii seed oil significantly increased the food intake and decreased the urinary volume per day in treated rats of the same groups in comparison with the period before the treatment intervention and attenuated body weight loss in the diabetic rats. Moreover, this effect of the oil was dose dependent. On the other hand, the oil did not affect their need for water. Conclusions: The results show that Opuntia dillenii seed oil has a very important antidiabetic effect on streptozotocin-induced diabetic rats. Hence, we suggest it as a preventive control of diabetes mellitus.

Media coverage of disasters potentially damages mental health. Moreover, its effects may differ as recipients may have different emotional responses toward media. The present study examined whether social capital, known to be protective against mental problems, influences a recipient’s emotional response toward news media broadcasting of natural disasters via newspapers, television and internet in Japan. Three social capital components, social participation, social support and cognitive social capital, were considered in the present study as each component reportedly had different effect on mental health. This nationwide cross-sectional survey was undertaken in 2015 among 1,200 Japanese citizens aged 15 to 79 years who were selected using the multi-stage sampling procedure. Data were collected via the drop-off pick-up method using a printed structured questionnaire. Negative and positive emotions were classified based on recipients’ responses against news media. Among 1,190 participants who reported emotions toward news media, 30.9% (368) had experienced any natural disasters, 37.4% (445) belonged to at least one formal or informal organization (social participation), 40.2% (478) had high social support, and 68.8% (819) had high cognitive social capital. High social support was associated with both reduced negative emotional response (OR 0.66, 95% Confidence Interval (CI) 0.47-0.93) and increased positive emotional response (OR 1.48, 95% CI 1.04-2.12) in multivariate analyses, while high cognitive social capital was only associated with increased positive emotional response (OR 1.62, 95% CI 1.11-2.37). These results suggest protective effects of social support and cognitive social capital against news media coverage of natural disasters.

The employment of the hexyl-substituted anion [HexCB(11)Cl(11)](-) allowed the synthesis of a Zn-II species, Zn[HexCB(11)Cl(11)](2), 3, in which the Zn2+ cation is only weakly coordinated to two carborate counterions and that is soluble in low polarity organic solvents such as bromobenzene. DOSY NMR studies show the facile displacement of at least one of the counterions, and this near nakedness of the cation results in high catalytic activity in the hydrosilylation of 1-hexene and 1-methyl-1cyclohexene. Fluoride ion affinity (FIA) calculations reveal a solution Lewis acidity of 3 (FIA=262.1 kJ mol(-1)) that is higher than that of the landmark Lewis acid B(C6F5)(3) (FIA=220.5 kJ mol(-1)). This high Lewis acidity leads to a high activity in catalytic CO2 and Ph2CO reduction by Et3SiH and hydrogenation of 1,1-diphenylethylene using 1,4-cyclohexadiene as the hydrogen source. Compound 3 was characterized by multinuclear NMR spectroscopy, mass spectrometry, single crystal X-ray diffraction, and DFT studies.

This study’s aim was to determine the pesticide residues in 10 different vegetable commodities from the Asir region, Saudi Arabia. We evaluated 211 vegetable samples, collected from supermarkets between March 2018 and September 2018, for a total of 80 different pesticides using ultrahigh-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) and gas chromatography-tandem mass spectrometry (GC-MS/MS) after extraction with a multi-residue method (the QuEChERS method). The results were assessed according to the maximum residue limit (MRL) provided by European regulations for each pesticide in each commodity. All lettuce, cauliflower, and carrot samples were found to be free from pesticide residues. A total of 145 samples (68.7%) contained detectable pesticide residues at or lower than MRLs, and 44 samples (20.9%) contained detectable pesticide residues above MRLs. MRL values were exceeded most often in chili pepper (14 samples) and cucumber (10 samples). Methomyl, imidacloprid, metalaxyl, and cyproconazole were the most frequently detected pesticides. Based on the results of this study, we recommend that a government-supported program for the monitoring of pesticide residues in vegetables be established to promote consumers’ health and achieve sustainable farming systems.

Flexible fiber-type solid-state supercapacitors (FSCs) are demanded for energy storage of wearable soft electronics. A flexible carbon fiber (CF) with high electrical conductivity and good energy storage ability can act as the current collector and the active material simultaneously. Improving the energy storage ability of the CF without depositing active materials is highly promising to avoid active materials from peeling off, especially under bending conditions. In this study, the CF is treated with acid mixtures containing different HNO3 to H2SO4 ratios. The roughened surface and the production of graphene quantum dots and functional groups are achieved for the acid-treated CF, especially for the CF treated with the acid mixtures. The largely enhanced specific capacitance (C-L) is first obtained for the optimized CF electrode (641.08 mF/cm at 5 mV/s) treated with the acid mixture containing the HNO3 to H2SO4 ratio of 1 to 3. The FSC also shows a maximum energy density of 16.57 mu W h/cm at the power density of 62.50 mu W/cm, as well as a C-L retention of 77% and Coulombic efficiency of 100% in 5000 times of a charge/discharge cycling process. Excellent flexibility is also attained for the FSC with no shape distortion of cyclic voltammetry curves measured under the bending angle of 180 degrees and with 1000 times of repeated bending. This work proposes a simple acid treatment to largely enhance the energy storage ability of pure CF electrodes. The bifunctional substance with current collecting and energy storing abilities is expected to be well developed in the future for applying on numerous efficient flexible energy storage devices.
