Light-driven nitrogen fixation to produce ammonia is a green and economical technology of nitrogen reduction but is still quite challenging, especially in an air atmosphere without any sacrificial ***, we demonstrate efficient photocatalytic nitrogen fixation using water and air directly by loading lanthanide–transition metal(4f–3d) cluster NdCo_(3) on two-dimensional P-doped graphitic carbon nitrides(PCN) material surface. Benefiting from the increase in the number of nitrogen vacancies(NVs) and highly matched band gap structure and excellent hole trapping ability of clusters, the NdCo_(3)/PCN photocatalyst exhibits efficient nitrogen reduction activity with 371(in air) and 825 μmol h^(-1)g^(-1)(in pure nitrogen)without any sacrificial reagents. The introduction of potassium sulfate inhibits hydrogen production and promotes nitrogen reduction activation. This work suggests that anchoring precisely structured clusters on 2D materials may enhance photocatalytic nitrogen reduction under normal temperature and pressure.

The shortage of organ donors mandates the use of liver allograft from anti-HBc(+) donors, especially in areas highly endemic for hepatitis B virus(HBV) infection. Theincidence of de novo hepatitis B infection(DNH) is over 30%-70% among recipients of hepatitis B core antibody(HBcA b)(+) grafts without any prophylaxis after liver transplantation(LT). Systematic reviews showed that prophylactic therapy [lamivudine and/or hepatitits B immunoglobulin(HBIG)] dramatically reduces the probability of DNH. However, there are limited studies regarding the effects of active immunization to prevent DNH, and the role of active vaccination is not welldefined. This review focuses on the feasibility and efficacy of pre- and post-LT HBV vaccination to prevent DNH in HBsA g(-) recipient using HBcA b(+) grafts. The presence of HBs Ab in combination with lamivudine or HBIG results in lower incidence of DNH and may reduce the requirement of HBIG. There was a trend towards decreasing incidence of DNH with higher titers of HBs Ab. High titers of HBs Ab(> 1000 IU/L) achieved after repeated vaccination could eliminate the necessity for additional antiviral prophylaxis in pediatric recipients. In summary, active vaccination with adequate HBsA b titer is a feasible, cost-effective strategy to prevent DNH in recipients of HBc Ab(+) grafts. HBV vaccination is advised for candidates on waiting list and for recipients after withdrawal of steroids and onset of low dose immunosuppression after transplantation.

Monosegment-preserving hepatic resections are very rarely considered in patients with locally advanced tumors given the high risk of liver failure from an inadequate liver remnant(1,2).Where this is considered,the associating liver partition and portal vein ligation for staged hepatectomy(ALPPS)technique,a two-staged procedure in order to induce remnant volume hypertrophy,have been reported(1,2).However,ALPPS has been known to have a high complication rate,hence even more infrequently,this complicated technique has been contemplated for pediatric patients(2).In the case we present,we identified an infant with a locally advanced hepatoblastoma with a unique anatomic presentation,that certainly precludes the possibility of ALPPS,but which otherwise provided the team with the opportunity to perform a single-staged monosegment-preserving hepatectomy with curative intent,in lieu of the alternative of liver transplantation(LT).
