BACKGROUND/AIMS Effector T cell activation is particularly important in the initiation of autoimmune uveitis. This pilot study seeks to demonstrate activation of human peripheral effector T cells in response to the uveitis candidate autoantigen, retinal S antigen (SAg), using cytokine flow cytometry (CFC). METHODS Peripheral blood mononuclear cell (PBMC) suspensions from uveitis patients and ...

This paper concentrates on the control of hybrid fuelcell (FC)/energystorage distributed generation (DG) systems under voltage sag in distribution systems. The proposed control strategy makes hybrid DG system work properly when a voltage disturbance occurs in distribution system, and it stays connected to the main grid. This controller determines the supercapacitor power that should be generate...

Microbial superantigens (SAGs) have been implicated in the pathogenesis of human autoimmune diseases. Preferential expansion of the Vveta7 T cell receptor positive T cell subset in patients suffering from acute-onset type I diabetes has indicated the presence of a surface membrane-bound SAG. Here, we have isolated a novel mouse mammary tumor virus-related human endogenous retrovirus. We further...

BACKGROUND A lumbar drainage catheter is frequently placed intra-operatively to decrease fluid pressure on the brain in aneurysmal subarachnoid cases. In rare cases, this catheter placement can lead to intracranial hypotension, resulting in brain stem herniation termed "brain sag" and it can lead to neurological injury and may prove to be fatal. We present our patient with brain sag secondary t...

In this paper, the impacts of installing superconducting fault current limiter (SFCL)in radial and loop power distribution system are evaluated to improve voltage sag in both cases of with and without distributed generations (DG). Among various SFCLs, the hybrid type with a superconducting element in parallel with a current limiting reactor (CLR) is selected. This is more effective than resisto...

Abstract— A new development of voltage control scheme for power quality improvement such as voltage sag, swell, harmonics, and transient conditions in three-phase power systems has been proposed. Faults occurring in power distribution systems or amenities can inject the voltage sag or swell. This fault can damage or affect the power transmission and distribution. For sensitive loads, the short ...

Many nervous systems contain rhythmically active subnetworks that interact despite oscillating at widely different frequencies. The stomatogastric nervous system of the crab Cancer borealis produces a rapid pyloric rhythm and a considerably slower gastric mill rhythm. We construct and analyze a conductance-based compartmental model to explore the activation of the gastric mill rhythm by the mod...

Bacterial superantigens (SAgs) have been implicated in inflammatory disease, and SAg-treated mice have increased jejunal T cells. Here we show that T84 cells (a human epithelial cell line) display increased MCP-1 and RANTES mRNA expression and protein production in response to conditioned medium from Staphylococcus aureus enterotoxin B (SEB; a model SAg)-activated immune cells. Also, MCP-1 and ...

Wavelet analysis approach is presented in this paper for the automatic detection and analysis of voltage sag in power systems with noise and without noise. Wavelet analysis is used to process the voltage waveform for detection and better estimation of the time-related parameters of a voltage Sag in voltage supply, The method proposed, which can be processed in real-time, has been simulated for ...

Global sensitivity analysis (GSA) is a fundamental tool for identifying input variables that determine the behavior of mathematical models under uncertainty. Among methods proposed to perform GSA, those based on Sobol method are highlighted because their versatility and robustness; however, applications using complex impractical owing significant processing time. This research proposes methodol...
