Trimetallic oxyhydroxides are one of the most effective materials for oxygen evolution reaction (OER) catalysis, a key process for water splitting. Herein, we describe a facile wet-chemical method to directly grow a series of coralloid trimetallic oxyhydroxides on arbitrary substrates such as nickel foam (NF) and carbon nanotubes (CNTs). The amount of iron in these oxyhydroxide sponges on NF and CNTs was precisely controlled, revealing that the electrocatalytic activity of the WCoFe trimetallic oxyhydroxides depends on the Fe amount in a volcano-like fashion...

Vinorelbine (NVB) is a semi-synthetic vinca alkaloid that is approved for the clinical therapy of lung cancer. However, the clinical application of NVB was limited because of the acquisition of resistance and inacceptable toxicity. Therefore, it is of great interest to develop low-cytotoxic drugs that can synergize with NVB. DT-13, a saponin monomer 13 of the Dwarf lilyturf tuber, showed inhibitory effects on tumor metastasis and angiogenesis in the previous studies. Here, we found that DT-13 combined with NVB exhibited synergistic effect to inhibit the cell proliferation in human lung cancer NCI-H1299 cells rather than human embryonic lung fibroblasts WI-38...

Severe acute pancreatitis (SAP) still remains a clinical challenge, not only for its high mortality but the uncontrolled inflammatory progression from acute pancreatitis (AP) to SAP. Cell death, including apoptosis and necrosis are critical pathology of AP, since the severity of pancreatitis correlates directly with necrosis and inversely with apoptosis Therefore, regulation of cell death from necrosis to apoptosis may have practicably therapeutic value. X-linked inhibitor of apoptosis protein (XIAP) is the best characterized member of the inhibitor of apoptosis proteins (IAP) family, but its function in AP remains unclear...

β-amyloid (Aβ) accumulation in the brain is the major pathophysiology of Alzheimer disease (AD). Hypertension is a risk factor for AD by promoting Aβ deposition. Traditional Chinese medicinal compound tongxinluo (TXL) can improve blood circulation and endothelium-dependent vasodilation. This study investigates the effects of TXL on cognition and Aβ accumulation using spontaneously hypertensive rats (SHRs). TXL was intragastrically administered to SHRs at low-dose, mid-dose and high-dose for 15, 30 or 60 days...

Epstein-Barr virus (EBV) is a human γ-herpesvirus associated with cancer, including Burkitt lymphoma, nasopharyngeal, and gastric carcinoma. EBV reactivation in latently infected B cells is essential for persistent infection whereby B cell receptor (BCR) activation is a physiologically relevant stimulus. Yet, a global view of BCR activation-regulated protein ubiquitination is lacking when EBV is actively replicating. We report here, for the first time, the long-term effects of IgG cross-linking-regulated protein ubiquitination and offer a basis for dissecting the cellular environment during the course of EBV lytic replication...

Metal carbenes are often proposed as reactive intermediates in the late transition metal-catalysed transformations of alkynes. Owing to their high reactivity, however, isolation and structural characterization of metal carbene intermediates in these transformations has remained unknown. Herein, we report the isolation of two acyclic gold and copper carbene intermediates in either Au(I)- or Cu(I)-catalysed cyclization of N-alkynyl formamidines through five-exo-dig cyclization. X-ray diffraction, (13)C NMR spectra data and computational analyses provide evidence for the formation of a gold carbene intermediate with a carbocation-like electronic character...
