Factor analysis has been used to deconvolute the different chemical states of Si, B, C and N, and to identify different compounds. The analysis of the as-implanted sample indicates the formation of a quaternary compound with an estimated average composition of SiB0.3C0.6N0.1 in a broad region...

2A). Regarding AA-99 and AA-100, the number of viable cells was reduced by at least two orders of magnitude at the concentration of the MIC, and four orders at 4 times the MIC (Fig. 2C, D). These results indicated that these three compounds had bactericidal effects on S. aureus N...
体外研究在存在500μM阿米洛利,100μMEIPA,10μM苯扎那和10μM苯胺的情况下,45Ca2 +摄取从79±9降至46±4(剩余58%),27±4(34%),29±5(分别为37%)和38±4(48%)pmol /卵母细胞/ 30分钟(n = 6,P = 0.008)。结果发现,EIPA,苯扎米尔和苯甲酰胺在-50 mV时迅速可逆地阻断Ca2 +激活的TRPP3通道激...
of the glycans and improve their fluorometric, UV, or MS detection. A wide variety of derivatization strategies with a large number of labeling reagents were developed28,29. Released glycans are often derivatized with fluorophore compounds such as 8-aminopyrene-1,3,6-trisulfonic acid (APTS), 2-...
The formation of COPI vesicles is regulated by the ARF family of GTPases26. Drugs such as brefeldin A (BFA27) and golgicide A (GCA28) interfere with COPI vesicle formation by inhibiting GBF1, a guanine nucleotide exchange factor required to activate ARF GTPases. BFA and GCA treatments sel...
Factor VIII organisation on nanodiscs with different lipid composition. Thromb. Haemost. 113(4) , 741-9, (2015) Nanodiscs (ND) are lipid bilayer membrane patches held by amphiphilic scaffolding proteins (MSP) of ~10 nm in diameter. Nanodiscs have been developed as lipid nanoplatforms for ...
The dynamics of antimicrobial resistance gene transfer remain unclear. Here, by integrating bacterial genome and metagenome data with machine learning the authors show that genetic incompatibility is a main limiting factor, while co-occurrence of bacteria in the human microbiome and wastewater contributes...
Concentrations of these chemicals were also slightly elevated at this station in the mid-depth sample. This suggests that the produced water plume was close to the bottom but extended to the mid-depth. From the bottom sample data, an average dilution factor of 5003.00 was calculated (Fig. 11...
Carbon-hydrogen (C–H) bond activation in a molecule is an efficient yet challenging route towards synthesis of complex organic compounds1,2,3,4,5due to the existence of multiple reactive sites6,7. By introducing heteroatoms, such as nitrogen and sulfur atoms into the organic skeleton, theorth...
