Although chronic pain has been linked to poorer psychosocial well-being in the spouse, the extent to which patient pain affects spouse sleep is unknown. The aim of the present study was to test the hypothesis that greater daily knee pain would be associated with poorer sleep for the spouse that evening. We also tested the hypothesis that this pain contagion is exacerbated in couples who have a close relationship. A total of 138 knee osteoarthritis (OA) patients and their spouses completed baseline interviews and a 22-day diary assessment. Multilevel lagged models indicated that greater knee OA pain at the end of the day was associated with spouses' poorer overall sleep quality that night and feeling less refreshed after sleep. In contrast, there was no evidence that spouse sleep was related to greater patient pain the next day. The effects of patient pain on spouse sleep were not due to disturbances in patient sleep and were also independent of spouse sex, depressive symptoms, and physical comorbidities; both partners' negative affect; and the quality of marital interactions throughout the day. As predicted, we also found that patient pain was more strongly related to less refreshing sleep for spouses who were in a close relationship. Findings illustrate that chronic pain may place the spouse's health at risk and suggest an important target for couple-oriented interventions., (Copyright © 2013 International Association for the Study of Pain.

This study examined agreement between patients and two role partners (spouses and physicians) on patients' pain severity and the relationships between dyadic agreement and patients' well-being. We hypothesized that compared to disagreement between patients and role partners, dyadic agreement would be related to better psychological well-being (more disease-specific self-efficacy and positive affect, and less depression). Participants were 114 older women with osteoarthritis, their caregiving husbands, and their rheumatologists. Among patient-spouse dyads, agreement was associated with better well-being, especially when compared to spouses' underestimation of patients' pain. Contrary to predictions, patient-physician agreement was not related to better patient well-being. Agreement between patients and physicians was associated with less (rather than more) self-efficacy and positive affect when compared to physicians' underestimation of patients' pain.

A number of indolyl thiazoles have been prepared and evaluated for their antitumor properties. The compounds were synthesized from the appropriate indole, building up the thiazole ring using the Hantzsch reaction. Cytotoxic activity was measured in the human breast cancer cell line SKBr3 using the MTT assay.

RB 90740 is the lead compound in a series of aromatic mono-N-oxide bioreductive drugs. The compound shows considerably greater toxicity towards hypoxic verses aerobic mammalian cells in vitro. The differential in concentration required to give the same level of cell killing under these conditions ranges from 3.5 in a human bronchio-alveolar tumor cell line up to 120 in a rodent cell line defective in the repair of DNA strand breaks. The ability of RB 90740 to cause DNA strand breaks under hypoxic conditions was confirmed by alkaline sucrose gradient and pulsed field gel electrophoresis techniques. Despite these properties demonstrated in vitro, RB 90740 was shown not to be cytotoxic to hypoxic cells in experimental murine tumors in vivo. This may be due, in part, to the level of hypoxia (< 0.02% O2) necessary to produce toxicity in vitro.

The mechanism of action of cyclopropamitosenes, novel bioreductive anticancer agents, has been investigated using a unique combination of chemical and biochemical techniques. The compounds 4 function as reductively activated alkylating agents under chemical reducing conditions, and the biochemical experiments establish that the methoxy- and aziridinyl-derivatives 4a and 4b behave differently upon bioreduction.
