The risk assessment of a fall in patients with lumbar spinal stenosis.

Study Design: A prospective case control study.

Objectives: To investigate the risk of a fall by using functional mobility tests in patients with lumbar spinal stenosis (LSS) via a comparison with patients with knee osteoarthritis (KOA).

Summary Of Background Data: LSS is a degenerative arthritic disease in the spine that results in decreasing function, impaired balance, and gait deficit, with increased levels of leg and back pain.

Determination of the prevalence of aspirin and clopidogrel resistances in patients with coronary artery disease by using various platelet-function tests.

Background: Dual therapy with aspirin and clopidogrel has emerged as the gold standard therapy for patients treated with drug-eluting stents (DES). However, there is variability in patients' responses to this antiplatelet therapy, and some patients continue to show ischemic recurrences after therapy. The purpose of the study was to compare the simultaneously obtained results of various platelet-function tests for assessing the prevalence of antiplatelet resistance in coronary artery disease patients undergoing DES therapy.

Maternal emotional availability at bedtime predicts infant sleep quality.

In the present study, linkages were examined between parental behaviors (maternal practices) at bedtime, emotional availability of mothering at bedtime, and infant sleep quality in a cross-sectional sample of families with infants between 1 and 24 months of age. Observations of maternal behaviors and maternal emotional availability were conducted independently by 2 sets of trained observers who were blind to data being coded by the other. With infant age statistically controlled, specific maternal behaviors at bedtime were unrelated to infant sleep disruptions at bedtime and during the night.

Conversion of oximes to carbonyl compounds with 2-nitro-4,5-dichloropyridazin-3(2H)-one.

Conversion of oximes to the carbonyl compounds has been demonstrated with use of 2-nitro-4,5-dichloropyridazin-3(2H)-one (2) under microwave irradiated conditions. Fourteen aliphatic and aromatic oximes converted to their corresponding aldehydes and ketones in good to excellent yields. It is noteworthy that the reaction is conducted under neutral, mild, and eco-friendly condition.

Synthesis of homo-N-nucleoside with 1,2,4-triazole-3-carboxamide.

On the basis of potent biological activities of ribavirin and homo-N-nucleosides, a novel homo-N-1,2,4-triazole-3-carboxamide derivative 1 was synthesized starting from 2,3,5-tri-O-benzoylribofuranosyl-1-acetate as a potential antiviral agent.
