Background Physical inactivity in patients with rheumatoid arthritis (RA) is a major problem with increased risks of co-morbidity and premature death. In order to address this problem we need more knowledge on factors that could change sedentary beha

A series of mono(disilylamino)phosphines and two related phosphines were treated with CCl4 either neat or in CH2Cl2. The reactions proceeded with elimination of CHCl3 and/or Me3SiCCl3 to form a variety of new P-chloro-N-silylphosphoranimines. The pre

The N-silyl phosphoranimines [e.g., Me3SiN=P(OCH2CF3)Me2] undergo a variety of reactions including deprotonation/substitution of the P-Me groups, transilylation, and condensation with reactive phosphines. Some new 1,2-addition and oxidation reactions

Subfemtomole quantities of ATP were determined using luminescence analysis with firefly extracts. The methodological advances include development of microtechniques for sample handling, and recording of the time profile of the light emission by photo
