A new silver-mediated 5-exo-dig cyclization of 2-alkynylbenzonitriles with disubstituted phosphine oxide and H2O has been developed. The reaction enables multiple bond-forming events including C-P, C-C and C-O bonds under atmospheric conditions, leading to the concise and direct formation of 28 examples of phosphorus-containing 1-indenones with generally good yields.

Characterization techniques available for bulk or thin-film solid-state materials have been extended to substrate-supported nanomaterials, but generally non-quantitatively. This is because the nanomaterial signals are inevitably buried in the signals from the underlying substrate in common reflection-configuration techniques. Here, we propose a virtual substrate method, inspired by the four-point probe technique for resistance measurement as well as the chop-nod method in infrared astronomy, to characterize nanomaterials without the influence of underlying substrate signals from four interrelated measurements...

BACKGROUND: Chloroquine, a bitter tastant, inhibits Ca(2+) signaling, resulting in suppression of B cell activation; however, the inhibitory mechanism remains unclear. RESULTS: In this study, thapsigargin (TG), but not caffeine, induced sustained intracellular Ca(2+) increases in mouse splenic primary B lymphocytes, which were markedly inhibited by chloroquine. Under Ca(2+)-free conditions, TG elicited transient Ca(2+) increases, which additionally elevated upon the restoration of 2 mM Ca(2+)...

Two-dimensional (2D) crystals exhibit unique and exceptional properties and show promise for various applications. In this work, we systematically studied the structures of a 2D boronphosphide (BP) monolayer with different stoichiometric ratios (BPx, x = 1, 2, 3, 4, 5, 6 and 7) and observed that each compound had a stable 2D structure with metallic or semiconducting electronic properties. Surprisingly, for the BP5 compounds, we discovered a rare penta-graphene-like 2D structure with a tetragonal lattice...

OBJECTIVE: Endothelial lipase (EL) is a key determinant in plasma high-density lipoprotein-cholesterol. However, functional roles of EL on the development of atherosclerosis have not been clarified. We investigated whether hepatic expression of EL affects plasma lipoprotein metabolism and cholesterol diet-induced atherosclerosis. APPROACH AND RESULTS: We generated transgenic (Tg) rabbits expressing the human EL gene in the liver and then examined the effects of EL expression on plasma lipids and lipoproteins and compared the susceptibility of Tg rabbits with cholesterol diet-induced atherosclerosis with non-Tg littermates...

Gene arrangements in the mitochondrial genomes (mitogenomes) of insects are conserved across the major lineages, but can be rearranged within derived groups and may provide valuable phylogenetic characters. In this study, we sequenced the entire mitogenome of Parasa consocia, a moth of the family Limacodidae (Lepidoptera: Zygaenoidea). Compared with other lepidopterans and ancestral insects, the P. consocia mitogenome features a transfer RNA gene arrangement novel among lepidopterans between the ND3 and ND5 genes: RANSEF (the underline signifies an inverted gene), which differs from the ARNSEF arrangement of ancestral insects...

PIWIL2-like (PL2L) protein 60 (PL2L60), a product of aberrantly activated PIWIL2 gene, is widely expressed in various types of tumors and may promote tumorigenesis. However, the mechanisms underlying the activation of expression of PL2L60 remain unknown. In this study, an intragenic promoter responsible for the activation of PL2L60 within the human PIWIL2 gene has been identified, cloned and characterized. The promoter of PL2L60 is located in the intron 10 of the host gene PIWIL2. Bioinformatic and mutagenic analysis reveals that this intragenic promoter within the sequence of 50 nucleotides contains two closely arranged cis-acting elements specific for the hepatic leukemia factor (HLF) in the positive strand and signal transducer and activator of transcription 3 (STAT3) in the negative strand...

Size-segregated water-soluble ionic species (WSIs) were measured using an Anderson cascade impactor from Jul. to Aug. 2008 and from Dec. 2009 to Feb. 2010 in urban Beijing. The results showed that fine particles (PM2.1, Dp < 2.1 μm) accounted for ∼49% (summer) and ∼34% (winter) of the total particulate mass, and WSIs accounted for 23-82% of the mass concentration of PM2.1. Secondary inorganic aerosols (SIAs, the sum of SO4(2-), NO3(-) and NH4(+)) accounted for more than 30% of the fine particles, which were greatly elevated during particle pollution events (PM events), thereby leading to an alteration of the size distributions of SO4(2-) and NO3(-) to nearly single fine-mode distributions peaking at 0...

AIMS: Increases in the systemic vasodilator adrenomedullin and the renal vasoconstrictors thromboxane A2 (TXA2 ) in cirrhotic patients are pathogenic factors for the development of functional acute-kidney-injury, including pre-renal azotemia (PRA) and hepatorenal syndrome (HRS), which is associated with high mortality. This study aims to find biomarkers which can diagnose HRS in early stage for treating it as soon as possible. METHODS: Acute decompensated cirrhotic patients who had been admitted to hospital were enrolled in this prospective cohort study...

We describe an enantioselective addition of Br-CX3 (X = Cl or Br) to terminal olefins that introduces a trihalomethyl group and generates optically active secondary bromides. Computational and experimental evidence supports an asymmetric atom transfer radical addition (ATRA) mechanism in which the stereodetermining step involves outer-sphere bromine abstraction from a (bisphosphine)Rh(II)BrCl complex by a benzylic radical intermediate. Beyond the synthetic utility, this mechanism appears unprecedented in asymmetric catalysis...

Arrhythmogenesis in acute myocardial infarction (MI) is associated with depolarization of resting membraine potential (RMP) and decrease of inward rectifier potassium current (IK1) in cardiomyocytes. However, clinical anti-arrhythmic agents that primarily act on RMP by enhancing the IK1 channel are not currently available. We hypothesized that zacopride, a selective and moderate agonist of the IK1/Kir2.1 channels, prevents and cures acute ischemic arrhythmias. To test this viewpoint, adult Sprague-Dawley (SD) rats were subjected to MI by ligating the left main coronary artery...

Molecular mechanisms that modulate liver regeneration are of critical importance for a number of hepatic disorders. Kupffer cells and natural killer (NK) cells are two cell subsets indispensable for liver regeneration. We have focused on these two populations and, in particular, the interplay between them. Importantly, we demonstrate that deletion of the myeloid phosphatase and tensin homolog on chromosome 10 (PTEN) leading to an M2-like polarization of Kupffer cells, which results in decreased activation of NK cells...

A copper(i)-mediated carboamination cascade reaction between vinyl azides and aryldiazonium salts is described. Functionally diverse N(2)-substituted 1,2,3-triazoles were obtained in moderate to good yields through novel difunctionalization of vinyl azides by aryldiazonium salt sources. This method has a wide scope, good functional-group tolerance and insensitivity to an ambient atmosphere.

Propofol can cause developing neuronal apoptosis in both in vivo and in vitro studies, and the mechanism is unclear till now. Our previous study has demonstrated that propofol can increase the TNF-α expression in the prefrontal cortex in rat developing brain, the TNF-α antagonist, etanercept, can inhibit propofol-induced neuronal apoptosis, but little is known about how TNF-α mediates that process. This study reveals that propofol at clinically relevant concentrations increases the TNF-α synthesis and release in neurons, and induces neuronal apoptosis; etanercept significantly reduces neuronal apoptosis, the elevation of cleaved caspase-8 and cleaved caspase-9, or the Akt phosphorylation induced by propofol, while the selective PI3K antagonist blocks the neuroprotection of etanercept...
