Protein conformational disorders, which include certain types of retinitis pigmentosa, are a set of inherited human diseases in which mutant proteins are misfolded and often aggregated. Many opsin mutants associated with retinitis pigmentosa, the most common being P23H, are misfolded and retained within the cell. Here, we describe a pharmacological chaperone, 11-cis-7-ring retinal, that quantit...

Impairment in mismatch negativity (MMN) generation is a robust biological marker of schizophrenia. Understanding the physiological and pharmacological processes involved in its generation may therefore advance our understanding of this complex disorder. The present study tested if acute administration of nicotine modulates human auditory sensory memory as measured with MMN. ERP responses to ton...

OBJECTIVES This study examined the relationship between stress, self-efficacy, self-medication, and pharmacological neuroenhancement (PNE) in the Swiss general population. METHODS Using the largest Swiss Internet panel, a sample of 10,171 employees and students (unweighted N=10,084) aged 15-74 years was recruited and asked to complete a self-administered online survey. The data were weighted ...

This study examined perceived learning barriers to and strategies for teaching clinical pharmacology to undergraduate nursing students. The purposes of this study were to discuss barriers and strategies for teaching clinical pharmacology to undergraduate nursing students and compare those findings to student evaluation responses. This study used a comparative, cross-sectional design and examine...

The roles of the extracellular domain of type II TGF-β receptor (TBRII-ECD) in physiological processes ranging from development to cancer to wound healing render it an attractive target for exploration with chemical tools. For such applications, large amounts of active soluble protein are needed, but the yields of TBRII-ECD we obtained with current folding protocols were variable. To expedite t...

1. There has been considerable interest in techniques recently developed for the study of arterial baroreceptor-cardiac reflex sensitivity based on analysis of spontaneous baroreflex sequences and on spectral analysis. This study examined how these newer techniques agreed with the established pharmacological methods in elderly subjects. 2. In 20 elderly subjects [10 hypertensive (clinic blood p...

background: to determine if the glidescope® videolaryngoscope (gvl) could attenuate the hemodynamic responses to orotracheal intubation compared with conventional macintosh laryngoscope. objectives: the aim of this relatively large randomized trial was to compare the hemodynamic stress responses during laryngoscopy and tracheal intubation using gvl versus mcl amongst healthy adult individuals r...

The effects of alpha-toxins from Bungarus multicinctus (alpha BuTX) and Naja naja siamensis (alpha NTX) were studied on synaptic responses and on extrasynaptic responses to focally applied acetylcholine (ACh), histamine (Hm), gamma-aminobutyric acid (GABA), and glutamate (glu) in neurons of the marine mollusc, Aplysia californica. Binding of 125I-alpha BuTX to Aplysia ganglia homogenates was ph...

This study addresses how gamma-aminobutyric acid-A(GABAA) and GABAC receptors confer distinct temporal properties to neuronal synaptic responses. The retina is a model system for the study of postsynaptic contributions to synaptic responses because GABAergic amacrine cells synapse onto neurons, which have different combinations of GABAA and GABAC receptors. It is not known, however, how GABAA v...

In the intestinal epithelium, activation of phosphatidylinositol 3-kinase (PI3-kinase)/AKT pathways, via growth factor-mediated signaling, has been shown to regulate cell proliferation and inhibit apoptosis. An immune-activated receptor critical for Th2 immune responses, IL-4Ralpha can also activate PI3-kinase via insulin receptor substrate (IRS)-dependent signaling. Here, using the intestinal ...
