To evaluate the effects of liothyronine (3,5,3'-triiodo-L-thyronine, T(3)) on Na(+) channel current (I(Na)) properties, I(Na) was recorded in adult guinea pig ventricular myocytes. T(3) (1 nM) acutely increased whole cell I(Na) and shifted the steady-state I(Na) inactivation curve dose dependently. When the pipette solution contained 100 microM GTP or GTPgammaS, the effect of T(3) on the whole ...

the effect of a distributed patch mass on the natural frequency of vibration of a laminated rectangular plate with simply supported boundaries is investigated. the third order displacement field of a composite laminated rectangular plate is defined using the two variable refined plate theory. equations of motion of the plate are obtained with the help of calculus of variation. parametric study ...

a new multiple c- slotted microstrip patch antenna is proposed.  a patch antenna is a wide-beam narrowband antenna. microstrip patch antenna consist of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. the patch can be designed in any possible shape and normally made by conducting material copper or gold. this paper presents design of a c- slotted ...

BACKGROUND AND AIM: We sought to carry out a systematic review and meta-analysis of the diagnostic value of ‎epicutaneous patch testing in patients with oral lichenoid lesions (OLLs).‎ METHODS: Bibliographic searches were conducted in electronic databases such as PubMed, the Cochrane library, ‎EBSCO, Scopus, Web of knowledge and Google scholar from January 1990 to December 2011. Search terms re...

The patch-clamp technique was used to study the properties and the density of conducting K and Na channels in the apical membrane of rat cortical collecting tubule. The predominant K channel observed in cell-attached patches (SK channels) had an outward single-channel conductance (with LiCl in the pipette) of 10 pS. The inward conductance (with KCl in the pipette) was 42 pS. The channel had a h...

Transmembrane ionic movements are thought to occur through special membrane areas or channels. Until recently, it has not been possible to study the properties of individual ionic channels, directly. We have used the extracellular patch clamp technique to resolve unitary sodium channels in enzyme-dissociated rabbit ventricular myocytes. Depolarizing voltage clamp steps elicited rectangular inwa...

Abstract—A novel compact open-ended L-shaped slot antenna with asymmetrical rectangular patch is demonstrated and designed for UWB applications. With the open-ended L-shaped slot and an asymmetrical rectangular patch fed by the micro-strip line, multiple resonant frequencies are excited and merged to form a measured widen operating bandwidth of 3.01 ∼ 11.30GHz with 10 dB return loss. The fracti...

False aneurysm degeneration is a known complication of patch aortoplasty for coarctation of the aortic isthmus. Open surgical treatment consists of prosthetic graft repair of the involved aorta, often requires circulatory arrest to achieve a safe proximal aortic control and perform proximal anastomosis, and finally is associated with substantial perioperative morbidity. Endografting of the dise...

This paper presents the design and development of simple low cost rectangular microstrip antenna for multiband operation. By incorporating U-slot of optimum geometry and open stubs at two opposite corners on the rectangular radiating patch the antenna operates between 1.815 to 9.01 GHz at different frequency bands with a virtual size reduction of 44.84% and gives broadside radiation characteris...

A 3-sided truncated microstrip patch antenna with semicircular open slot for ultra-wideband (UWB) and SHF (Super High Frequency) applications has been presented in this paper. The proposed antenna is compact in size and designed on FR4 substrate. From the simulation and measurement results, it is shown that the corner-truncated With Semi Circular open slot patch scheme is an excellent approach,...
