The present study introduced "facial normality" to explain the inconsistency of previous research. We hypothesized that symmetry only increased facial attractiveness when it improved facial normality. We manipulated symmetry and normality simultaneously on sixteen Chinese male faces and asked participants to rate the perceived symmetry, perceived normality, and facial attractiveness. The results demonstrated an interactive effect of symmetry and normality on facial attractiveness. The structural equation model results showed two paths from symmetry to facial attractiveness (1) Symmetry reduced facial attractiveness by decreasing perceived normality; (2) Symmetry increased facial attractiveness by increasing the perceived symmetry and then improving perceived normality. In other words, perceived normality acted as a mediator between symmetry and facial attractiveness. The present study provides a solution to the different effects of symmetry on facial attractiveness in previous studies and suggests that future studies on symmetry and facial attractiveness should consider the mediating role of normality.The deep-sea ecosystem is considered as the largest and most remote biome of the world. It is meaningful and important to elucidate the life origins by exploring the origin and adaptive genetic mechanisms of the large deep-sea organisms. Sea cucumbers (Holothuroidea) are abundant and economically important group of echinoderms, living from the shallow-waters to deep-sea. In this study, we present the mitochondrial genomes of the sea cucumber Chiridota heheva and Chiridota sp. collected from the deep-sea cold seep and hydrothermal vent, respectively. This is the first reported mitochondrial genomes from the order Apodida. The mitochondrial genomes of C. heheva (17,200 bp) and Chiridota sp. (17,199 bp) display novel gene arrangements with the first protein-coding gene rearrangements in the class Holothuroidea. Bases composition analysis showed that the A + T content of deep-sea holothurians were significantly higher than that of the shallow-water groups. We compared the arrangement of genes from the 24 available holothurian mitogenomes and found that the transposition, reverse transposition and tandem-duplication-random-losses (TDRL) may be involved in the evolution of mitochondrial gene arrangements in Holothuroidea. Phylogenetic analysis revealed that the Apodida clustered with Elasipodida, forming two basal deep-sea holothurian clades. The divergence between the deep-sea and shallow-water holothurians was located at 386.93 Mya, during the Late Devonian. Mitochondrial protein-coding genes of deep-sea holothurians underwent relaxed purifying selection. There are 57 positive selected amino acids sites for some mitochondrial genes of the three deep-sea clades, implying they may involve in the adaption of deep-sea sea cucumbers.

Quality of life stands for the comprehensive assessment for health conditions and the central concerns in the seniors' care. The inter-relationship between health-related quality of life (HRQoL) and multimorbidity among community-dwelling healthy older adults remains uncertain.

Data of 1839 participants from the I-Lan Longitudinal Aging Study were excerpted for analysis. Functional status and HRQoL were measured by the Functional Autonomy Measurement System and the Chinese version of 12-item Short-Form Health Survey version 2. Poor HRQoL was defined as lowest quintile of physical and mental components summaries (PCS and MCS). learn more Multivariable linear and logistic regression analysis were applied to explore associations between variables of interest.

Adjusted for potential confounders, multivariable linear regression showed that multimorbidity and functional impairment were negatively associated with PCS (β coefficients -1.8 vs. -8.4) and MCS (β coefficients -1.9 vs. -4.8). Logistic regression affirmed similar associations that the odds of being poor HRQoL were 1.6 (95% CI 1.1-2.2) for multimorbidity, and 5.4 (95% CI 2.8-10.3) for functional impairment in PCS; 1.9 (95% CI 1.4-2.6) for multimorbidity and 6.0 (95%CI 3.2-11.5) for functional impairment in MCS. Adjusted for depressive symptoms and cognitive performance, functional impairment was significantly associated with poor physical component (OR4.68, 95% CI 0.35-19.34, p<0.001) and mental component in HRQoL (OR2.4, 95% CI 1.1-5.5, p=0.032), but the associations were insignificant in multimorbidity.

Findings from the study strengthened the importance of functional performance on HRQoL among community-living middle-aged and older adults, which is essential in community health promotion activities and health service programs.

However data about the combined effects of MPs and other contaminants is still limited. This study aimed to evaluate the impact of MPs and the heavy metal copper (Cu) on zebrafish (Danio rerio) larvae development and behavior. Zebrafish embryos were subchronically exposed to MPs (2 mg/L), two sub-lethal concentrations of Cu (60 and 125 µg/L) and binary mixtures of MPs and Cu using the same concentrations, from 2-h post fertilization until 14 days post fertilization. Lethal and sub-lethal responses (mortality, hatching, body length) were evaluated during the embryogenesis period, and locomotor, avoidance, anxiety and shoaling behaviors, and acetylcholinesterase (AChE) activity were measured at 14 dpf. The results showed that survival of larvae was reduced in groups exposed to MPs, Cu and Cu+MPs. Regarding the behavioral patterns, the higher Cu concentration and mixtures decreased significantly the mean speed, the total distance traveled and the absolute turn angle, demonstrating an adverse effect on swimming competence of zebrafish larvae. Exposure to MPs and Cu, alone or combined, also affected avoidance behavior of zebrafish, with larvae not reacting to the aversive stimulus. There was a significant inhibition of AChE activity in larvae exposed to all experimental groups, compared to the control group. Moreover, a higher inhibition of AChE was noticed in larvae exposed to MPs and both Cu+MPs groups, comparatively to the Cu alone groups. Our findings demonstrate the adverse effects of MPs, alone or co-exposed with Cu, on fish early life stages behavior. This study highlights that MPs and heavy metals may have significant impacts on fish population fitness by disrupting locomotor and avoidance behaviors.From the recent market trend, there is a huge demand for the bioactive compounds from various food matrices that could be capable enough to combat the emerging health effects in day-to-day life. Fenugreek is a well-known spice from ancient times for its medicinal and health benefits. In the present study, two methods of green extraction microwave (MAE) and ultrasound (UAE) assisted were studied in regard of extraction of fenugreek diosgenin. In this study, solvent type (acetone, ethanol, hexane and petroleum ether), solvent concentration (40, 60, 80 and 100%) and treatment time (1.5, 3.0, 4.5 and 6.0 min and 30, 40, 50 and 60 min for MAE and UAE method respectively) was varied to observe the effect of these parameters over extract yield and diosgenin content. The results of this study revealed that treatment time, type of solvent and its concentration and method adopted for extraction of diosgenin has significant effect. In relation with better yield extract and diosgenin content, the yield of fenugreek seed extract was 7.83% with MAE and 21.48% with UAE of fenugreek seed powder at 80% ethanol concentration at 6 and 60 min respectively. The content of diosgenin was observed in fenugreek seed powder extract was 35.50 mg/100 g in MAE and 40.37 mg/100 g in UAE with 80% ethanol concentration at 6 and 60 min respectively. The overall range of yield of fenugreek extract was varied from 1.04% to 32.48% and diosgenin content was 15.82 mg/100 g to 40.37 mg/100 g of fenugreek seed powder including both extraction methods. This study revealed that UAE would impose better ways for preparing fenugreek extract and observing diosgenin content from fenugreek seeds.In this study, a novel, simple, high yield, and scalable method is proposed to synthesize highly porous MoS2/graphene oxide (M-GO) nanocomposites by reacting the GO and co-exfoliation of bulky MoS2 in the presence of polyvinyl pyrrolidone (PVP) under different condition of ultrasonication. Also, the effect of ultrasonic output power on the particle size distribution of metal cluster on the surface of nanocatalysts is studied. It is found that the use of the ultrasonication method can reduce the particle size and increase the specific surface area of M-GO nanocomposite catalysts which leads to HDS activity is increased. These nanocomposite catalysts are characterized by XRD, Raman spectroscopy, SEM, STEM, HR-TEM, AFM, XPS, ICP, BET surface, TPR and TPD techniques. The effects of physicochemical properties of the M-GO nanocomposites on the hydrodesulfurization (HDS) reactions of vacuum gas oil (VGO) has been also studied. Catalytic activities of MoS2-GO nanocomposite are investigated by different operating conditions. M9-GO nanocatalyst with high surface area (324 m2/g) and large pore size (110.3 Å), have the best catalytic performance (99.95%) compared with Co-Mo/γAl2O3 (97.91%). Density functional theory (DFT) calculations were also used to elucidate the HDS mechanism over the M-GO catalyst. It is found that the GO substrate can stabilize MoS2 layers through weak van der Waals interactions between carbon atoms of the GO and S atoms of MoS2. At both Mo- and S-edges, the direct desulfurization (DDS) is found as the main reaction pathway for the hydrodesulfurization of DBT molecules.This work studied the use of a horizontal high-solid digester for the decentralized anaerobic treatment of horticultural waste (fallen leaves), where the effect of intermittent mixing by a modified double helical ribbon impeller was investigated. Before experimental verification, the flow pattern and theoretical mixing time were first characterized by CFD simulation. Subsequently, three mixing time intervals (i.e., 3 min/3 hr; 18 min/3 hr; 108 min/3 hr) and one control setup (i.e., without mixing) were compared for their performance during start-up and semi-continuous operation. It was found that minimal mixing was necessary for an efficient digester's start-up but increased mixing intensity for semi-continuous operation. The results were further interpreted by correlating the digester performance and microbial communities. Those microorganisms sensitive to increased mixing intensity were highlighted and analysed.
