Mice learn to identify and discriminate sugar solutions based on odor cues.

This study examined how olfaction impacts ingestive responses of mice to sugar solutions. Experiment 1 asked whether naïve C57BL/6 (B6) mice could identify 1 M glucose, fructose, or sucrose solutions based on odor cues, during a 30-min 2-bottle acceptability test. We tested mice both before and after they were rendered anosmic with ZnSO4 treatment.

Nature As Medicine: Mind, Body, and Soil.

Debate over the evidence supporting integrative care interventions not infrequently references the challenges funding research on natural agents and practices that are not patentable. The subject of this column goes to the mother of all such interventions, nature herself. Yet in this case, the authors report an awakening of research that affirms nature's power in health and well-being.

Data on the effect of sex on the size, cellular content, and neuronal density of the developing brain in mice exposed to isoflurane and carbon monoxide.

The data presented here detail the changes in size, cellular content, and neuronal density of the developing brain over time with respect to sex in C57Bl/6 mice following neonatal exposure to isoflurane, carbon monoxide, or their combination. Specifically, brain weight- and brain volume-to-body weight ratios are presented, representative immunoblots of whole brain cell-specific protein content are depicted, and quantification of the number of neurons in the primary somatosensory cortex and CA3 region of the hippocampus are shown. Three discrete postnatal time points are represented: P7 (prior to exposure), P14 (one-week post exposure), and P42-56 (5-7 weeks post exposure).

Carbon monoxide incompletely prevents isoflurane-induced defects in murine neurodevelopment.

Background: Commonly used anesthetics have been shown to disrupt neurodevelopment in preclinical models. It has been proposed that such anesthesia-induced neurotoxicity is mediated by apoptotic neurodegeneration in the immature brain. Low dose carbon monoxide (CO) exerts cytoprotective properties and we have previously demonstrated that CO inhibits isoflurane-induced apoptosis in the developing murine brain.

Pilot validation of a self-report outcome measure of complementary and alternative medicine.

Background: We previously developed a multidomain, self-report outcome measure relevant to a wide range of complementary and alternative medical (CAM) therapies. We report the results of a pilot study to validate the measure.

Methods: Fifty-two patients (60% female, mean age, 53 years) seeking services from CAM providers completed a battery of measures prior to a scheduled visit.
