Ultra-thin N-doped-graphene encapsulated Ni nanoparticles coupled with MoO2 nanosheets are prepared for HER and OER. As used for overall water splitting, it can work for 196 h at 1000 mA cm−2.

Myxobacterial predation on bacteria has been investigated for several decades. However, their predation on fungi has received less attention. Here, we show that a novel outer membrane β-1,6-glucanase GluM from Corallococcus sp. strain EGB is essential for initial sensing and efficient decomposition of fungi during predation. GluM belongs to an unstudied family of outer membrane β-barrel proteins with potent specific activity up to 24,000 U/mg, whose homologs extensively exist in myxobacteria. GluM was able to digest fungal cell walls efficiently and restrict Magnaporthe oryzae infection of rice plants. Genetic complementation with gluM restored the fungal predation ability of Myxococcus xanthus CL1001, which was abolished by the disruption of gluM homolog oar. The inability to prey on fungi with cell walls that lack β-1,6-glucans indicates that β-1,6-glucans are targeted by GluM. Our results demonstrate that GluM confers myxobacteria with the ability to feed on fungi, and provide new insights for understanding predator-prey interactions. Considering the attack mode of GluM, we suggest that β-1,6-glucan is a promising target for the development of novel broad-spectrum antifungal agents.

N-doped TiO2 with a three-dimensionally ordered macroporous structure was fabricated by a one-step colloidal crystal-template method, which showed excellent photocatalytic activity under visible-light irradiation.

Although patients with thyroid cancer have a very good prognosis overall, in this study, they often experienced more problems than the community reference population, independent of their age and sex. Sex, education, marital status, employment status, weight status, per capita disposable income, number of surgeries, type of surgery, physical activity per week, fruit intake, and levothyroxine intake per day are important correlates of HRQoL of thyroid cancer survivors. Awareness of these relevant factors could help healthcare professionals provide better supportive care.

We developed a room temperature ligand-assisted colloidal method to synthesize single-crystalline CsPbBr3 nanowires (NWs) directly from precursor powders.

To investigate the prevalence and risk factors for pterygium in rural older adults in Shandong Province, eastern China, a population-based, cross-sectional study was performed from April to July 2008. By means of cluster random sampling methods, a total of 19,583 people aged 50 years or above were randomly selected from four rural counties. Out of 19,583 people, 1,767 residents were excluded mainly because they were migrant workers when this study was performed. Finally, 17,816 (90.98%) people were included as eligible subjects. They received a comprehensive eye examination and a structured questionnaire voluntarily. Patients with pterygium were defined as having pterygium at the time of survey or pterygium surgery had been performed. 1,876 people were diagnosed as pterygium, either unilateral (1,083) or bilateral (793), which is equivalent to a prevalence of 10.53% (95% CI, 10.08–10.98). The multivariate logistic regression analysis showed that pterygium was independently associated with older age, areas, outdoor time, educational level, and use of hat and/or sunglasses. The prevalence of pterygium increased with age and hours spent under sunshine per day. Meanwhile, the higher the educational level and the more use of hat and/or sunglasses, the lower the pterygium prevalence.
