Periodontitis can cause damage to dental support tissue and affect the function of periodontal ligament cells. Rutin, a common flavonoid, plays a key role in anti-inflammatory responses, tissue repair and bone development. The purpose of this study was to investigate the effects of rutin on the oxidative stress, proliferation, and osteogenic differentiation of human periodontal ligament stem cells (PDLSCs) in an inflammatory environment and the underlying mechanism. Lipopolysaccharide (LPS) was used to stimulate PDLSCs to mimic an inflammatory environment model. Reactive oxygen species (ROS) levels were detected by the dichlorodihydrofluorescein diacetate (DCFH-DA) probe and the oxidative stress factors were tested by an oxidative stress factor detection kit. Moreover, the proliferation of PDLSCs was evaluated by cell counting kit-8 (CCK-8) assay. In addition, the osteogenic differentiation of PDLSCs was determined by alkaline phosphatase (ALP) staining, ALP activity test, alizarin red staining, and alizarin red semi-quantitative analysis. Furthermore, the protein levels of AKT and p-AKT were detected by Western blot. The results showed that rutin inhibited the release of ROS and increased the secretion of oxidative stress factors [superoxide dismutase (SOD) and glutathione (GSH)] and promoted the proliferation of PDLSCs in an inflammatory environment. Moreover, rutin upregulated ALP activity and enhanced the number of mineralized nodules. Conversely, the use of LY294002 (an inhibitor of PI3K) blocked the activation of the PI3K/AKT signaling pathway and prevented the beneficial effects of rutin. In conclusion, rutin promoted the antioxidative stress ability, proliferation and osteogenic differentiation of PDLSCs through PI3K/AKT signaling pathway in LPS-induced inflammatory environment.This study was designed to determine the effect of fishmeal (FM) replacement with soybean meal (SBM) in the diet of tilapia (Oreochromis niloticus). Growth, digestive enzyme activity, antioxidation, and gut histomorphology were assessed in the fish fed with five different formulated diets that increasingly replaced FM. The SBM0 contained 100% FM, followed by 25% (SBM25), 50% (SBM50), 75% (SBM75), and 100% (SBM100). Juvenile tilapia having weight and length of 6.6 ± 0.1&nbsp;g and 5.4 ± 0.2&nbsp;cm, respectively, were randomly divided into five treatment groups. Each group had 40 individual fish and fed to visual satiation for 90&nbsp;days. Body weight gain and specific growth rate in fish fed with 25-75% SBM increased significantly (P&nbsp; less then  0.01) compared with those in fish fed with SBM100. Fish having the same weight fed with diets SBM50, SBM75, and SBM100 showed a significantly (P&nbsp; less then  0.01) longer intestine compared with those fed with SBM0 and SBM25. Villus height of the stomach and intestine was significan health, and activities of digestive enzymes and antioxidant enzymes in O. niloticus.Aloe vera is a traditional medicinal plant; however, its use in fish is fairly recent. [https://www.selleckchem.com/products/icec0942-hydrochloride.html CT7001 order] We evaluated the effects of dietary A. vera on stress, innate immunity, and energy metabolism in pacu inoculated with Aeromonas hydrophila. For 7&nbsp;days, 192 fish were fed with diets supplemented with 0% (control), 0.5%, 1.0%, and 2.0% of the plant extract and then inoculated with bacteria and sampled 3, 6, and 24&nbsp;h later. All concentrations of A. vera reduced basal levels of cortisol, and 1.0% reduced cortisol levels more intensely 3&nbsp;h after inoculation. A. vera increased the basal respiratory activity of leukocytes/RAL (0.5 and 1.0%), increased the serum levels of lysozyme (1.0 and 2.0%) 6&nbsp;h after inoculation, and increased the activity of the complement system after 3&nbsp;h. Spleen somatic index/SSI increased with 1.0 and 2.0% A. vera. A. vera also promoted metabolic effects. It increased basal levels of lipids in the liver and muscle, as well as hepatosomatic index (1.0%) and, 3&nbsp;h after inoculation, prevented the reduction of serum triglyceride (1.0%) and reduced the mesenteric fat (1.0%). Bacterial inoculation increased RAL from 3 to 24&nbsp;h and lysozyme levels at 24&nbsp;h, increased serum cholesterol at 24&nbsp;h, and decreased serum triglyceride from 3 to 24&nbsp;h, regardless of A. vera. We concluded that A. vera offered for only 7&nbsp;days had stress-reducing effects, stimulated innate immunity, protected triglyceride levels in blood, lipid depots in the liver and muscle, and directed the energy mobilization to visceral depots.D-π-A chromophore derived coumarins are studied using "DFT and TD-DFT" to compute vertical excitation as well as NLO properties using "global hybrid" (GH) functionals B3LYP and BHandHLYP and "range separated hybrid" (RSH) functionals CAM B3LY', wB97, wB97X, and wB97XD with basis set 6-311++G(d,p) and "correlation consistence polarized valence double and triple zeta" cc-pVDZ and cc-pVTZ respectively in the gas phase and two solvents, N,N-Dimethylformamide (DMF) and ethyl acetate (EA). The trends in absorption and emission values calculated by TD-DFT using all the above mentioned functional and basis sets were studied and it was observed that the trends seen in the computed parameters using B3LYP, BHandHLYP and CAM B3LYP are in good agreement with the trends in experimental values. DFT calculations were performed to determine "static dipole moment" (μ), "linear polarizability" (α), "first order hyperpolarizability" (β0), "second order hyperpolarizability" (γ). We have calculated the mean average errors in dipole moment, linear polarizability, first and second hyperpolarizability and vertical excitation. We have observed large values of 'first order hyperpolarizability' (301-938 × 10^-30 e.s.u) and 'second order hyperpolarizability' (684-2498 × 10^-34) and they can act as good nonlinear optical materials. Also, vibrational contribution indicates the red shifted absorption and emission in 2c. They show higher values of electrophilicity index which indicates the stability and reactivity of molecules.Sex-typed play behavior shows large sex differences and seems to be affected by prenatal sex hormones. For example, a smaller, more male-typical ratio between the second and fourth digit length (2D4D), a proposed marker for prenatal testosterone exposure, has been shown to be related to sex-typed play preference in childhood. Nevertheless, it is still being debated whether 2D4D displays a stable sex difference throughout childhood, as there are few longitudinal studies. In the present study, children's 2D4D was measured on both hands on four occasions from early infancy to early childhood (T1 5&nbsp;months, T2 9&nbsp;months, T3 20&nbsp;months, and T4 40&nbsp;months) providing the rare possibility to test the temporal stability of the sex difference. Parents completed the Preschool Activities Inventory at T4 and reported on the number of older brothers and sisters as a measure for socialization influences. Parents described boys as playing more masculine and less feminine than girls. Boys had smaller 2D4D than girls at all measurements (T1-T4) and on both hands (right/left).
