Synthesis and SAR of novel oxazolidinones: discovery of ranbezolid.

Novel oxazolidinones were synthesized containing a number of substituted five-membered heterocycles attached to the 'piperazinyl-phenyl-oxazolidinone' core of eperezolid. Further, the piperazine ring of the core was replaced by other diamino-heterocycles. These modifications led to several compounds with potent activity against a spectrum of resistant and susceptible gram-positive organisms, along with the identification of ranbezolid (RBx 7644) as a clinical candidate.

Design, synthesis and activity of novel derivatives of oxybutynin and tolterodine.

Novel derivatives of Tolterodine (1) and Oxybutynin (2) have been designed using conformationally restricted azabicyclics as replacement for open-chain amines. The synthesis and structure-activity relationships are presented.

My love is hurting: the meaning spouses attribute to their loved ones' pain during palliative care.

The purpose of this qualitative study was to develop our knowledge of the pain experiences of family members by addressing the meaning of cancer pain to the spouse of a patient receiving palliative care. In particular, this study explored factors associated with the meanings the spouses ascribe to the experience of pain during palliative care and whether the meanings the patients attributed to pain were similar to the meanings held by the spouse. Two different states emerged, the "in-pain state" and the "out of pain state". The spouses described feelings of helplessness, fear, and unfairness when witnessing their loved one in pain. Once the pain had been controlled, spouses described feelings of peace and relaxation, and felt this meant that the couple could return to their old routines because their spouse was still alive. It was discovered that the meanings placed on the cancer pain differed for the spouse and the patient, with the spouse focusing on future consequences. Implications and suggestions for nursing practice and future research are proposed.

Glassy dynamics in granular compaction: sand on random graphs.

We discuss the use of a ferromagnetic spin model on a random graph to model granular compaction. A multispin interaction is used to capture the competition between local and global satisfaction of constraints characteristic for geometric frustration. We define an athermal dynamics designed to model repeated taps of a given strength. Amplitude cycling and the effect of permanently constraining a subset of the spins at a given amplitude is discussed. Finally we check the validity of Edwards's hypothesis for the athermal tapping dynamics.
