Abstract
A novel series of diaryl bicyclic azole-amines that are potent selective negative modulators of metabotropic glutamate receptor 5 (mGluR5) were identified through rational design. An initial hit compound 5a of modest potency (IC(50) = 1.2 μM) was synthesized. Evaluation of structure-activity relationships (SAR) on the left-hand side of the molecule revealed a preference for a 2-substituted pyridine group linked directly to the central heterocycle. Variation of the central azolo-amine portion of the molecule revealed a preference for the [4,5-c]-oxazoloazepine scaffold, while right-hand side variants showed a preference for ortho- and meta-substituted benzene rings linked directly to the tertiary amine of the saturated heterocycle. These iterations led to the synthesis of 29b, a potent (IC(50) = 16 nM) and selective negative modulator that showed good brain penetrance, high receptor occupancy, and a duration of action greater than 1 h in rat when administered intraperitoneally. Formal PK studies in rat and Rhesus monkey revealed a short half-life that was attributable to high first-pass clearance.

Abstract
In brief: During an 18-month period 61 patients who had problems associated with aerobic dance were evaluated. Fifty-four had overuse injuries, including all but two of the 24 patients who were instructors. The authors used three-phase radionuclide scintigraphy to evaluate some of the injuries and prescribed balanced orthoses for the management of pain related to lower extremity malalignment. Most of the injuries occurred when people began exercising vigorously after a period of inactivity.

Abstract
Insertion element IS121 was mapped between proA and a previously mapped IS5A element in two F-prime plasmids. Results of hybridizations of IS121 to chromosomal DNA from four other strains suggest that IS121 is normally present at this position in the chromosomes of Escherichia coli K-12 strains.
