of plasma membrane α- d -glucosldases, whereas the simultaneous azo-coupling procedures seemed to be less suitable for the quantification of surface membrane proteases, due to, for example, interactions of diazonium salts with amino acid or peptide substrates, reaction products and peptide ...

In the United States, Black individuals have higher rates of cancer mortality than any other racial group. Here, we examine chromosome copy number changes in cancers from more than 1800 self-reported Black patients. We find that tumors from self-reported
In fact, for a catalyst to be industrially viable, it must be able to withstand the reaction conditions repeatedly. The rates of reaction upon re-using the catalysts must not change dramatically (or at all in fact). It is commonly observed that heterogeneous catalysts undergo deactivation or ...
We then applied a DNA-based analysis to the isolated colonocytes to detect colorectal cancer cells originating from any part of the colorectum. The purpose of the present study was to determine how long after defecation and at what temperature the fecal samples should be stored to isolate the...
During air injection into an oil reservoir, an oxidation reaction generates some heat to raise the reservoir temperature. When the reservoir temperature re... JJ Sheng,EL Yang - 《Petroleum Science》 被引量: 0发表: 0年 The Relationship between Oceanic Heat Transport and Surface Fluxes in the ...
In illuminated cultures of an anaerobic photosynthetic bacterium the hydroxylated carotenoids may originate from lycopene by the specific hydration of a (louble bon(d of the unsaturatedI precursor. This reaction would resemble hydlration reactions of fumarase and crotonase. The reaction of unsaturatecd...
In this work, we propose changing the microstructure by modifying the curing rate of the epoxy amine reaction. There are two major questions that need to be answered: What is the effect of increasing the reaction rate up to gelation? Can the reaction proceed so quickly that the microgels are...
rate of mass transfer rises between gas andphotocatalystsurface, which leads to enhancement of reaction rate [29,154]. In case of higher residence time (at lower flowrate), VOC molecules have a more chance to be adsorbed oncatalyst surface. In consequence, number of compounds that reacts with...
