Heat recovery by combined heat and power (CHP) systems to provide load reduces the cost of microgrid (MG) energy management. However, transfer from CHP consumers is limited due loss pipelines. The amount varies depending on pipeline material environmental characteristics. Here, a day-ahead management CHP-based microgrid, including various types supply electrical thermal loads, performed. In thi...

Freshly dissociated myocytes from nonpregnant, pregnant, and postpartum rat uteri have been studied with the tight-seal patch-clamp method. The inward current contains both INa and ICa that are vastly different from those in tissue-cultured material. INa is abolished by Na+-free medium and by 1 microM tetrodotoxin. It first appears at approximately -40 mV, reaches maximum at 0 mV, and reverses ...

The modulation of L-type Ca2+ current (ICa) by changes in stimulation frequency was investigated in single ventricular cardiomyocytes isolated from guinea pig hearts. Electrical recordings were carried out at 21-25 degrees C and at 33-37 degrees C with the whole-cell patch clamp method, under K(+)-free conditions. A comparison is made between the response to frequency changes for ICa in the bas...

BACKGROUND AND PURPOSE Our study evaluated noninvasive tests for the diagnosis of atheromatous internal carotid artery (ICA) pseudo-occlusion. METHODS Twenty patients (17 men, 3 women; mean age +/-SD, 64.3+/-11.6 years) with angiographically proven atheromatous ICA pseudo-occlusion (20 vessels) were prospectively examined with MR angiography (MRA; 2D and 3D time-of-flight techniques), color D...

Combined heat and power (CHP) systems are employed to supply electrical thermal loads of distribution networks (DNs). However, the loss can significantly hinder transfer through pipelines from CHP consumers Therefore, optimal placement sizing reduce losses, including very crucial. To minimize loss, many methods have been proposed for resource allocation. In this paper, a new approach allocation...

Icariin (ICA) is a major component isolated from Epimedium brevicornum. Emerging evidence shows that ICA can inhibit tumor cell proliferation, invasion and migration. However, the anti-cancer effect of ICA on B16 cells has not been fully investigated. Here we found that the proliferation of B16 cells was inhibited by ICA in a concentration- and time-dependent manner, and the colony formation of...

Icariin (ICA), the main active flavonoid glucoside isolated from Herba Epimedii, has been shown to prevent postmenopausal bone loss in vitro. However, the mechanisms by which ICA prevents bone loss in vivo remain poorly understood. In the present study, the effect of ICA in an ovariectomized (OVX) rat model of osteoporosis was evaluated. Sprague-Dawley rats were divided into sham-operated and O...

Biofilm formation in Staphylococcus epidermidis is mediated by icaADBC-dependent and -independent pathways. Subinhibitory concentrations of erythromycin, azithromycin, and clarithromycin enhanced, in a dose-dependent manner, the level of biofilm formation by 20% (21/105 isolates) by macrolide-resistant ica-positive and -negative isolates tested in vitro. The presence of ica, however, apparently...

It has been well documented that matrine, a tetracyclo-quinolizindine alkaloid, possessed a positive inotropic effect. However, the underlying mechanisms at the cellular and ion channel levels have not been completely clarified. Therefore, the present study was designed to identify the cellular target and the mechanisms of inotropic effect of matrine. Guinea pig papillary muscles were used to s...

Independent component analysis (ICA) is an unsupervised technique for blind source separation, and the ICA algorithms using nongaussianity as the measure of mutual independence have been also used for projection pursuit or visualization of multivariate data for knowledge discovery in databases (KDD). However, in real applications, it is often the case that we fail to extract useful latent varia...
