Here we report an effective bottom-up solution-phase process for the preparation of nitrogen-doped porous carbon scaffolds (NPCSs), which can be employed as high-performance anode materials for both lithium-ion batteries (LIBs) and sodium-ion batteries (SIBs). The as-obtained NPCSs show favorable features for electrochemical energy storage such as high specific surface area, appropriate pore size distribution (3.9 nm in average), large pore volume (1.36 cm(3) g(-1)), nanosheet-like morphology, a certain degree of graphitization, enlarged interlayer distance (0...

To explore the role of the testicular leptin and JAK-STAT(LEP-JAK-STAT) pathway in testosterone biosynthesis during juvenile stages and exercise for weight loss, male C57BL/6J mice were randomly divided into normal-diet (ND) and high-fat diet (HFD) groups. After 10 weeks, mice in the HFD group were further divided randomly into obese control (OC), obese moderate-volume exercise (OME), and obese high-volume exercise (OHE) groups. Mice in the OME group were provided with 2 h/day, 6 days/week swimming exercise for 8 weeks and mice in the OHE group underwent twice the amount of daily exercise intervention as the OME group...

Three-dimensional topological insulators (3D TIs) represent states of quantum matters in which surface states are protected by time-reversal symmetry and an inversion occurs between bulk conduction and valence bands. However, the bulk-band inversion, which is intimately tied to the topologically nontrivial nature of 3D Tis, has rarely been investigated by experiments. Besides, 3D massive Dirac fermions with nearly linear band dispersions were seldom observed in TIs. Recently, a van der Waals crystal, ZrTe5, was theoretically predicted to be a TI...

Growth Differentiation Factor 8 (GDF8), also called myostatin, is a member of the transforming growth factor (TGF)-β super-family. As a negative regulator of skeletal muscle growth, GDF8 is also associated with bone metabolism. However, the function of GDF8 in bone metabolism is not fully understood. Our study aimed to investigate the role of GDF8 in bone metabolism, both in vitro and in vivo. Our results showed that GDF8 had a negative regulatory effect on primary mouse osteoblasts, and promoted receptor activator of nuclear factor κB ligand (RANKL)-induced osteoclastogenesis in vitro...

Despite high theoretical energy density, the practical deployment of lithium-sulfur (Li-S) batteries is still not implemented because of the severe capacity decay caused by polysulfide shuttling and the poor rate capability induced by low electrical conductivity of sulfur. Herein, we report a novel sulfur host material based on "sea urchin"-like cobalt nanoparticle embedded and nitrogen-doped carbon nanotube/nanopolyhedra (Co-NCNT/NP) superstructures for Li-S batteries. The hierarchical micromesopores in Co-NCNT/NP can allow efficient impregnation of sulfur and block diffusion of soluble polysulfides by physical confinement, and the incorporation of embedded Co nanoparticles and nitrogen doping (∼4...

BACKGROUND: Drought stress is one of the most severe problem limited agricultural productivity worldwide. It has been reported that plants response to drought-stress by sophisticated mechanisms at both transcriptional and post-transcriptional levels. However, the precise molecular mechanisms governing the responses of tobacco leaves to drought stress and water status are not well understood. To identify genes and miRNAs involved in drought-stress responses in tobacco, we performed both mRNA and small RNA sequencing on tobacco leaf samples from the following three treatments: untreated-control (CL), drought stress (DL), and re-watering (WL)...

Angiogenesis is modulated by a multitude of pro-angiogenic factors including VEGFR-2, Tie-2, and EphB4. Moreover, their crosstalk also had been well elaborated. We have identified several diarylurea-based VEGFR-2 inhibitors as potential anti-angiogenesis agents. As a continuation to our previous research, two series of diaryl malonamide and diaryl thiourea derivatives have been developed as multiplex VEGFR-2/Tie-2/EphB4 inhibitors. Interestingly, the biological evaluation indicated that several compounds bearing trifluoromethyl or trifluoromethoxyl exhibited promising multiplex inhibition against angiogenesis-related VEGFR-2, Tie-2, and EphB4...

Fenton's reagent, ultrasound, and the combination of Fenton's reagent and ultrasound were used to pretreat rice straw (RS) to increase its enzymatic digestibility for saccharification. The characterization shows that compared with ultrasound, Fenton's reagent pretreatment was more efficient in increasing the specific surface area and decreasing the degree of polymerization (DP) of RS. The enzymatic hydrolysis results showed that the RS pretreated by ultrasound-assisted Fenton's reagent (U/F-RS), which exhibited the largest specific surface area and the lowest DP value, had the highest enzymatic activity, and the amount of reducing sugar released from U/F-RS at 48h of enzymatic saccharification is about 4 times as large as that from raw RS and 1...

BACKGROUND: Water ingestion induces the osmopressor response, which typically presents as increased total peripheral vascular resistance in young healthy subjects. A previous study has suggested that the RBC membrane receptor is involved in osmopressor stress. Recent studies have indicated nitric oxide synthase phosphorylation in RBCs. However, the main process in signaling pathway activation to elicit such a response is unknown. Herein, we hypothesized that hypo-osmotic stress following water ingestion modulates the eNOS/NO pathway, thereby alternating vascular resistance...

This paper reports a convenient method for the synthesis of highly fluorescent Au nanoclusters (NCs) via electrostatically induced phase transfer. Furthermore, on the basis of an aggregation-induced fluorescence quenching mechanism, the potential application for Cu(2)(+) sensing on the fluorescence emission of the Au NCs is discussed. These prepared fluorescent Au NCs offer acceptable sensitivity, high selectivity, and a limit of quantitation of 0.02 μM for the measurement of Cu(2)(+) , which is lower than the maximum level (1 ppm, equals to 15...

OBJECTIVE: Individuals with Parkinson's disease are more likely to develop melanoma, and melanoma patients are reciprocally at higher risk of developing Parkinson's disease. Melanoma is strongly tied to red hair/fair skin, a phenotype of loss-of-function polymorphisms in the MC1R (melanocortin 1 receptor) gene. Loss-of-function variants of MC1R have also been linked to increased risk of Parkinson's disease. The present study is to investigate the role of MC1R in dopaminergic neurons in vivo...
