In this work, thin multilayer of In(OH)3 successfully decorated on the surface of MoS2 nanosheets (NSs) by simple facile hydrothermal method. MIn-2 with Mo:In mass ratio of 1:0.5 was formed 3D ...flower-like hierarchical architecture which was made up of MoS2 NSs and In(OH)3 thin little multilayers. MIn-2 sensor exhibits ultrahigh response of 15.39, and shows ultrafast response time of 1.6 s-100 ppm NOx gas at room temperature (RT), detects NOx concentration as low as 0.1 ppm; It also shows excellent stability at 30 and 5 ppm NOx gas after 8 consecutive weeks. The response of MIn-2 is almost 13 times higher than pure MoS2 NSs. The synergistic effect between flower like MoS2 NSs with thin layer In(OH)3 restacking effect of MoS2 layer and also ensure the ultrafast response and long life device. This work will provide feasible routes to synthesized MoS2 based highly active gas sensing devices to detect noxious gases.
•Overload lithium decreased glucose tolerance in broiler chickens.•Overload lithium increased insulin sensitivity in broiler chickens.•Overload lithium decreased gluconeogenesis in the liver and ...skeletal muscle.•Overload lithium increased glucose transport in the liver and skeletal muscle.
Lithium, like insulin, activates glycogen synthase and stimulates glucose transport in rat adipocytes. To investigate the effect of dietary overload lithium on glucose metabolism in broiler chickens, one-day-old chicks were fed a basal diet supplemented with 0 (control) or 100mg lithium/kg (overload lithium) for 35days. Compared to controls, glucose disappearance rates were lower (p=0.035) 15–120min after glucose gavage, and blood glucose concentrations were lower (p=0.038) 30min after insulin injection in overload lithium broilers. Overload lithium decreased (p<0.05) glycogen and glucose-6-phosphate concentrations in liver, but increased (p<0.05) their concentrations in pectoralis major. Overload lithium increased (p<0.05) mRNA expression of glucose transporter (GLUT) 3 and GLUT9 in liver, and GLUT1, GLUT3, GLUT8, and GLUT9 in pectoralis major, but decreased (p<0.05) cytosolic phosphoenolpyruvate carboxykinase (PEPCK) in liver and mitochondrial PEPCK in pectoralis major. These results suggest that dietary overload lithium decreases glucose tolerance and gluconeogenesis, but increases insulin sensitivity and glucose transport in broiler chickens.
The aim of this study was to determine how attitudes toward the return of genomic research results vary internationally.
We analyzed the “Your DNA, Your Say” online survey of public perspectives on ...genomic data sharing including responses from 36,268 individuals across 22 low-, middle-, and high-income countries, and these were gathered in 15 languages. We analyzed how participants responded when asked whether return of results (RoR) would motivate their decision to donate DNA or health data. We examined variation across the study countries and compared the responses of participants from other countries with those from the United States, which has been the subject of the majority of research on return of genomic results to date.
There was substantial variation in the extent to which respondents reported being influenced by RoR. However, only respondents from Russia were more influenced than those from the United States, and respondents from 20 countries had lower odds of being partially or wholly influenced than those from the United States.
There is substantial international variation in the extent to which the RoR may motivate people’s intent to donate DNA or health data. The United States may not be a clear indicator of global attitudes. Participants’ preferences for return of genomic results globally should be considered.

Leg problems often result from the rapid weight gain and poor bone quality in modern ducks, leading to a high risk of fractures and continuous pain. We hypothesized that improving bone quality in ...combination with delaying weight gain via a low nutrient density (LND) diet probably reverses these skeletal abnormalities. Studies indicated that 25-hydroxycholecalciferol (25-OH-D3), a vitamin D3 metabolite, is effective in treating bone-related disorders. Therefore, Exp. 1 evaluated the effects of 25-OH-D3 on tibial mass of meat ducks. Male meat ducklings were fed a standard nutrient density diet (containing a regular vitamin regimen) without or with 25-OH-D3 at 0.069 mg/kg for 35 d. The results showed that 25-OH-D3 supplementation improved the mineral content, microarchitecture and mechanical properties of tibias, and this companied by a decreased serum bone resorption marker and a concomitant decrement in osteoclast-specific marker genes expression. Subsequently, Exp. 2 was conducted to examine the impacts of 25-OH-D3 incorporating an LND diet on tibial quality of ducks under 2 different vitamin regimens (regular and high). Ducklings were allocated to a 2 × 2 factorial arrangement with 2 kinds of vitamin premixes and without or with 25-OH-D3 at 0.069 mg/kg in LND diets. The high premix had higher levels of all vitamins except biotin than the regular premix. The results demonstrated that high vitamin diets exhibited more significant effects than regular vitamin diets on inhibiting bone turnover and increasing minerals deposition. Tibial mineral content, microarchitecture, and strength of birds under the regular vitamin regimen were increased by 25-OH-D3 supplementation; However, these positive effects were not observed in ducks under the high vitamin regimen. To conclude, 25-OH-D3 supplementation improves tibial mass by suppressing osteoclast-mediated bone resorption in meat ducks, and this positive impact only was observed in regular but not high vitamin regimen when birds fed an LND diet.
The three dimensional (3D) interlayer rGO/SnO2/PPy nanohybrids, based on reduced graphene oxide (rGO) obtained from expanded graphene (EG), SnO2 nanoparticles (NPs) and polypyrrole (PPy) were ...obtained by facile method. The rGO/SnO2/PPy nanohybrid electrodes were composed of a thin conducting film of PPy on the surface of rGO/SnO2 (EG: Sn molar ratio of 1.2:1), used for the determination of ultra-trace ions (Cd2+, Cu2+, Hg2+ and Pb2+) with the square wave anodic stripping voltammetry (SWASV) technique. Among the rGO/SnO2/PPy, rGO/SnO2 (rGS), rGO/PPy (rGP) and pure polypyrrole (PPy) samples, the sensitivity and current density of rGO/SnO2/PPy-4 (rGS: PPy mass ratio of 1:4), have shown excellent performance for the recognition of above ultra-trace heavy metal ions (HMIs). The limit of detection (3σ method) of the rGO/SnO2/PPy-4 nanohybrids modified electrode toward Cd2+, Cu2+, Hg2+ and Pb2+ ions was 7.5 × 10−13, 8.3 × 10−13, 8.1 × 10−13 and 8.8 × 10−13 mol L-1 (M), respectively. The 3D interlayer rGO/SnO2/PPy nanohybrid is a favorable material constructed for multiple functionalities having the advantages of conducting material PPy, active site SnO2 NPs and outstanding electrical substrate graphene nanosheet (obtained from EG) in electrochemical detection of HMIs.

The 3D hierarchical structure S-PEdot/EG with homogenous ridgelike surface morphology was achieved by intercalating 3,4-ethylenedioxythiophene monomers between the interlayers of EG using a vacuum-assisted method. The composition of the nanohybrids and the π-π interaction between the EG and PEdot molecules were characterized by using Raman spectroscopy, thermogravimetric analysis, and X-ray photoelectron spectroscopy. The nanohybrid with an EG content of 10%exhibited excellent capacitive performance with a high capacitance of 139.6 Fg^sup -1^ at 1.0 Ag^sup -1^ in 1 m LiClO^sub 4^ electrolyte. In the two-electrode symmetric supercapacitors, the device performed with a high energy density of 6.83 Whkg^sup -1^ at the power density of 146 Wkg^sup -1^, and retained high stability during the charge-discharge process. The excellent performance can be attributed to the 3D hierarchical structure, the π-π interaction between EG and PEdot molecules, andthe doped SFA as an immobilized counter-ion. This cost-effective and simple methodused to fabricate 3D S-PEdot/EG nanohybrids is promising for the generation of electrode materials for high-performance supercapacitors.
