A DNA strand-transfer reaction is an early step in the transposition of phage Mu. It has been shown that an efficient reaction in vitro requires, in addition to buffer and salt, only the Mu A protein, Mu B protein, host protein HU, ATP, and Mg2+. We have determined that, of the three protein factors involved, only the Mu B protein has an ATPase activity. The Mu B ATPase is stimulated by Mu A pr...

background: this work investigated the dosimetry limitations of the random and systematic uncertainties of sliding window (sw) intensity modulated radiation therapy (imrt). materials and methods: a varian 21ex linear accelerator, pinnacle3 treatment planning system and radiographic film dosimetry was used. the limitations of the sw were studied using beam modulation ranging from 2 to 100 mu/bea...

‎Let $M(X‎, ‎mathcal{A}‎, ‎mu)$ be the ring of real-valued measurable functions‎ ‎on a measure space $(X‎, ‎mathcal{A}‎, ‎mu)$‎. ‎In this paper‎, ‎we characterize the maximal ideals in the rings of real measurable functions‎ ‎and as a consequence‎, ‎we determine when $M(X‎, ‎mathcal{A}‎, ‎mu)$ is a hereditary ring.

Fentanyl, and its structural analogs lofentanil and sufentanil, are potent analgesics used clinically in the management of pain. However, the high analgesic potency of these compounds is limited by the development of tolerance after chronic use. To investigate whether their tolerance development may be related to mu receptor desensitization, the cloned mouse mu receptor as well as mutant forms ...

Analysis of mu-specific mRNA in the B cell tumor line, BCL1, shows that the cells contain predominantly mRNA for mu chain of membrane-bound immunoglobulin M (IgM) (2.7 kb, mu m mRNA). Stimulation of the cells to Ig secretion by lipopolysaccharide (LPS) results in a 6-12 fold increase in amount of mRNA for the mu chain of secreted IgM (2.4 kb mu s mRNA). The increase in mu s mRNA is accompanied ...

Mu suppression has been proposed as a signature of the activity of the human mirror neuron system (MNS). However the mu frequency band (8-13 Hz) overlaps with the alpha frequency band, which is sensitive to attentional fluctuation, and thus mu suppression could potentially be confounded by changes in attentional engagement. The specific baseline against which mu suppression is assessed may be c...
