Example sentences for: acr
How can you use “acr” in a sentence? Here are some example sentences to help you improve your vocabulary:
Residues of ACR1 to ACR5 of CD39 have been mutated to study the involvement of the ACR regions in catalysis.
ACR = American College of Rheumatology; CRP = C-reactive protein; DMARD = disease-modifying antirheumatic drug; IL = interleukin; NF = nuclear factor; RA = rheumatoid arthritis; rhIL-11 = recombinant human IL-11; TNF = tumor necrosis factor.
The inability of rhIL-11 to bring about a statistically significant improvement in the ACR 20% criteria may also be the result of an inability of rhIL-11 to stimulate the synthesis of acute-phase proteins, of the significant clinical response of several placebo-treated patients, or of a lack of adequate power of the study to show efficacy.
Figure 1describes the data using the 20% ACR criteria for response at the various doses or schedules tested.
NTPDases do not form phosphorylated intermediates during catalysis, a conclusion also supported by lack of vanadate sensitivity and Pi product inhibition [ 3 4 5 6 ] . The catalytic reaction appears to be irreversible and no partial reactions have been observed [ 7 8 ] . Divalent cations like Ca 2+or Mg 2+are required for activity, and maximal activity is reached when the concentrations of substrates and divalent cations are equal [ 1 ] . The specific activities of NTPDases vary over a broad range from ten thousand units for potato apyrase to less than one hundred units for chicken gizzard ecto-ATPase [ 9 10 ] . Sequence comparisons indicate that most of NTPDases contain five highly conserved regions, apyrase conserved region, ACR1 - ACR5 [ 9 11 ] . However, the catalytic sites have not been identified, although ACR1 and ACR4 have been implicated in β- and γ-phosphate binding, respectively [ 9 ] .
