introduction: it is believed that locus coeruleus (lc) influences the sensory information processing. however, its role in cortical surround inhibitory mechanism is not understood. in this experiment, using controlled mechanical displacement of whiskers we investigated the effect of phasic electrical stimulation of lc on response of layer v barrel cortical neurons in anesthetized rat. methods: ...

Ahn B, Beharry AW, Frye GS, Judge AR, Ferreira LF. NAD(P)H oxidase subunit p47 is elevated, and p47 knockout prevents diaphragm contractile dysfunction in heart failure. Am J Physiol Lung Cell Mol Physiol 309: L497–L505, 2015. First published July 24, 2015; doi:10.1152/ajplung.00176.2015.—Patients with chronic heart failure (CHF) have dyspnea and exercise intolerance, which are caused in part b...

introduction: systemic application of capsaicin to neonatel rodents depletes their primary afferent c-fibers and also results in a wide variety of changes observable in adulthood. the manual methods used for stimulation of vibrissa provide limited information on response properties of barrel cortical neurons. in this study the effect of c-fiber depletion induced by neonatal capsaicin (cap) trea...

The use of esophageal recordings of the diaphragm electromyogram (EMG) signal strength to evaluate diaphragm activation during voluntary contractions in humans has recently been criticized because of a possible artifact created by changes in lung volume. Therefore, the first aim of this study was to evaluate whether there is an artifactual influence of lung volume on the strength of the diaphra...

[Purpose] The purpose of this study was to examine effects of diaphragm breathing exercise applied on the basis overload principle on respiratory function. [Subjects and Methods] The subjects of this study were 35 normal adults. They were randomly assigned to two group; the maneuver-diaphragm exercise group and self-diaphragm exercise group. The respiratory function was evaluated using the Card...

evaluating existing flexible pavement condition is a pre-requisite to choose improvement technique that has to be adopted to enhance its quality. to evaluate existing pavements, non-destructive testing methods are desirable. benkelman beam and 5th wheel bump integrator are used to conduct non-destructive tests like deflection and roughness surveys on the existing pavement of 4 lane divided carr...

In congestive heart failure (CHF), diaphragm weakness is known to occur and is associated with myosin loss and activation of the ubiquitin-proteasome pathway. The effect of modulating proteasome activity on myosin loss and diaphragm function is unknown. The present study investigated the effect of in vivo proteasome inhibition on myosin loss and diaphragm function in CHF rats. Coronary artery l...

Main results 2 trials met the selection criteria: 1 trial compared the Prentif Cavity Rim Cervical Cap (Lamberts Ltd, Oxford, UK) with the Ortho diaphragm (Ortho Pharmaceutical Corporation, Raritan, NJ, USA) (n=1529, 6–24 mo follow up), and 1 trial compared the FemCap cervical cap (rubber manufactured by Hi-Tech Rubber, Anaheim, CA, USA) with the All-Flex diaphragm (Ortho) (n=841, 28 wk follow ...

when very large floating structure) vlfs (is heavily loaded in the central portion, the difference deflection between its central section and its corners would increase. one cost effective solution for reducing the differential deflection is gill cell. gill cells are compartments in the vlfs that the buoyancy forces are eliminated at their locations. in this study, for examine the gill cells be...
