Notes

Terahertz photoconductive aerial determined by antireflection dielectric metasurfaces along with inserted plasmonic nanodisks.
Under the conditions of this experiment, no significant effects were found on immune function of F3 SD rats through the three generation development study of genetically modified maize with CrylAb and epsps genes.
In order to investigate the effect of yeast on reducing mycotoxin damage in dried fish.

A strain of Meyerozyma guilliermondii MH 211588. 1(MG-81) was mixed and fermented 48 h with dried Lutjanus erythopterus which contaminated aflatoxin B_1(AFB_1) and T-2 toxin(T-2). The toxin concentration in fermentation at different time was detected by LC-MS/MS, and fermentation was fed with mice by intragastric administration(7 d). Blood routine and four liver function enzymes were measured by hematology analyzer and microplate spectrophotometer respectively. The elimination effect of MG-81 isolate on mycotoxin damage in dried fish was evaluated by the toxin concentration at different time and its toxic effect on mice.

The removal rates of AFB_1 and T-2 in dried fish fermentation showed a parabolic linear growth trend with the prolongation of fermentation time. The removal rates of AFB_1 and T-2 in dried fish fermentation broth tended to be stable at 36 h(the removal rates of AFB_1 and T-2 were 83. 7%±1. 3% and 78. 5%±0. 8%). This indicated that 36 h was the optimal time for MG-81 to remove mycotoxins in dried fish. At the same time, it was found that there was no significant change in the indexes of MG-81 dried fish fermentation compared with the control group(P>0. 05), while the same dose of AFB_1 and T-2 dried fish fermentation(without MG-81), the leucocytes, lymphocytes, erythrocyte, hemoglobin, platelet and mean platelet volume of mice were significantly lower than those of control group(P>0. 05), showing obvious hemotoxicity and immunotoxicity. The activity of four liver enzymes was increased significantly(P<0. 05), showing obvious hepatotoxicity.

The fermentation of MG-81 for 36 h can effectively remove AFB_1 and T-2 from dried fish and eliminate their hazards.

To understand the rural sanitary conditions in different geographical areas of Shaanxi Province.

According to the stratified random sampling method, 30 agriculture-related counties were selected(The central area includes 13 counties in Xi'an, Tongchuan, Weinan, Xianyang and Baoji cities. The southern area includes 10 counties in Hanzhong, Ankang, Shangluo cities. Fedratinib The northern area includes 7 counties in Yulin, Yan'an cities. ). Five townships were selected randomly in each county(excluding Chengguan Town), and 4 administrative villages were selected randomly in each township as survey villages, which were collected the soil samples for testing lead, cadmium and chromium in each subject village, and 5 households were randomly selected in each villages as survey households. The data was obtained through data reading, interviews, on-site observations, and laboratory testing, etc. The detection of soil lead and cadmium was carried out according to the Measurement of Soil Quality Lead and Cade central area than in the southern area and northern area. Sanitation toilets have a low penetration rate in the province, which was higher in the southern area than in the central area and the northern area. The domestic garbage was randomly discarded, and domestic sewage was randomly discharged, which was more in the northern area than in the central area and the southern area. Soil cadmium pollution was relatively heavy, mainly in the southern area.
To explore the role of calcium/calmodulin-dependent protein kinase Ⅱ(CaMK-Ⅱ) and protein phosphatase-2 A(PP2 A) on hyperphosphorylation of tau induced by AlCl_3 in SH-SY5 Y cell.

SH-SY5 Y cells were assigned to the control group, AlCl_3 low, middle, high exposed groups(200, 400800 μmol/L Al~(3+)), KN93 intervention group(800 μmol/L Al~(3+)+0. 5 μmol/L KN93) and sphingosine intervention group(800 μmol/L Al~(3+)+5 nmol/L sphingosine). After 48 h of exposure and intervention, the viabilities of cells were measured by CCK-8 assay, the contents of CaMK-Ⅱ and PP2 A were determined by ELISA, and the expression of tau5 and phosphorylation of Thr-181, Thr-231, Ser-262 and Ser-396 were detected by Western-Blot.

The viabilities of cells in AlCl_3 middle and high exposed groups were significantly lower than that of the control group(P<0. 05). Compared with the AlCl_3 high exposed group, the viabilities of cells in KN93 intervention group and sphingosine intervention group were significantly increased(P&l mainly regulates the phosphorylation of Ser-262 induced by AlCl_3, while PP2 A mainly regulates the phosphorylation of Thr-181, Thr-231 and Ser-396 induced by AlCl_3. It is suggested that hyperphosphorylated tau protein induced by AlCl_3 is closely related to PP2 A.
To explore the effect of combined oral exposure of titanium dioxide nanoparticles(TiO_2 NPs) and glucose on blood glucose homeostasis in young SD rats.

Eighty 4-week-old young SD rats were randomly divided into 8 groups(10 rats in each group, half male and half female). The rats were exposed to TiO_2 NPs through intragastric administration at 0, 2, 10 and 50 mg/kg with or without 1. 8 g/kg glucose daily for 30 days. Blood glucose was monitored weekly during the experiment. Oral glucose tolerance test(OGTT) was carried out after subacute exposure(30 days), and the biomarkers related to blood glucose homeostasis were detected, including the contents of glycosylated serum protein(GSP), glycosylated hemoglobin(HbA1 c), insulin, C-peptide and glucagon. At the same time, the pancreatic pathology of rats was observed.

TiO_2 NPs were anatase crystals, closely spherical shape, with an average particle size of(24±5)nm. Exposure of TiO_2 NPs alone had little effect on blood glucose homeostasis. Blood glucose decresing in temporary hypoglycemia and impaired glucose tolerance, as well as adaptive changes of blood glucose-regulating hormones. The male rats were more sensitive. Compared with the exposure of TiO_2 NPs alone, the combined exposure of TiO_2 NPs and glucose induced more significant effects. Significant synergistic effect between them occurred on postprandial blood glucose.
