Two-directional ring-opening cross-metathesis.

Two-directional ring-opening cross-metathesis of a range of cyclic alkenes with a variety of electron deficient alkenes has been accomplished; it was found that the process is quite general and gives complete selectivity for the E,E-dienes, making this a very useful and high-yielding protocol for two-directional chain synthesis.

Mindfulness-based stress reduction and health-related quality of life: findings from a bilingual inner-city patient population.

Objective: To determine whether completing a mindfulness-based stress reduction (MBSR) program would affect the general health, health-related quality of life, sleep quality, and family harmony of Spanish- and English-speaking medical patients at an inner-city health center.

Materials And Methods: An intervention group of 68 patients (48 Spanish-speaking and 20 English-speaking) completed the SF-36 Health Survey and two additional questions about sleep quality and family harmony before and after completing the 8-week MBSR program. A comparison group of 18 Spanish-speaking patients who received no intervention completed the same questionnaire at the same intervals.
