Ruthenium complexes extract electrons from illuminated p-type Si through a native SiOx layer with photovoltage of 570 mV.
Protoporphyrinogen oxidase (Protox) inhibitors and other com pounds which block o r stim ulate the porphyrin pathway can cause sufficient levels o f porphyrins to accum ulate in plant tissues for severe photodynam ic dam age to occur. The gross sym ptom ology for all o f these p o r phyrinogenic herbicides is similar. Porphyrin accum ulation induced by three porphyrinogenic herbicides acifluo...
SAR125844 is a potent and selective inhibitor of the c-Met kinase receptor. This was an open-label, phase I, multicenter, dose-escalation, and dose-expansion trial of SAR125844 in Asian patients with solid tumors, a subgroup of whom had gastric cancer and MET amplification (NCT01657214). SAR125844 was administered by intravenous infusion (260-570 mg/m2) on days 1, 8, 15, and 22 of each 28-day c...
To investigate the flotation separation behavior of petalite and quartz, various methods were employed in this study. These included micro-flotation experiments, a contact angle analysis, zeta potential Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron (XPS) to explore mechanism modified ether amine reagent (L0-503) for quartz under weakly alkaline conditions. The test results...
Human cytochrome P450 2E1 (CYP2E1) catalyzes themetabolism of numerous xenobiotics, including acetaminophen and ethanol. CYP2E1 expression is known to be extensively regulated by posttranscriptional and post-translational mechanisms. A previous study had reported that a single-nucleotide polymorphism (SNP) 1561A>G in the 39-untranslated region (39-UTR) of CYP2E1 leads to a decreased CYP2E1 mRNA...
The present study was conducted to test the hypothesis that low concentrations of coated ZnO, as a substitute for a high concentration of ZnO (2250 mg Zn/kg), could improve intestinal immunity function and regulate microbiota composition, thus alleviating the incidence of diarrhoea in weaned piglets. A total of eighty-four cross-bred piglets, weaned at an age of 28 (SEM 1) d, were allocated ran...
Bordetella adenylate cyclase toxin-hemolysin (CyaA, AC-Hly, or ACT) permeabilizes cell membranes by forming small cation-selective (hemolytic) pores and subverts cellular signaling by delivering into host cells an adenylate cyclase (AC) enzyme that converts ATP to cAMP. Both AC delivery and pore formation were previously shown to involve a predicted amphipathic alpha-helix(502-522) containing a...
