This paper analyses the risk of failure associated with control methods for overvoltages due to compact transmission-line (CTL) energization. The Approximate Statistical Insulation Coordination Method is applied different verify which will be very suitable long CTL. results are analyzed according devices and configurations using pre-insertion resistor, controlled switching and, surge arrester. ...

The sampling technique used was Cluster Random Sampling. sample amounted 22 students in group B. test results instrument showed that reliability ability 0.921. data analysis simple regression analysi...

This study presented the effects of carrier-transporting layer (CTL) on electroluminescence (EL) performance a blue phosphorescent organic light-emitting diodes (PHOLEDs) with electron transporting host based three kinds electron-transporting layers (ETLs) including 3-(4-biphenyl-yl)-4-phenyl-5-(4-tert-butylphenyl)-1,2,4-triazole (TAZ), diphenyl-bis[4-(pyridin-3-yl)phenyl]silane (DPPS) and 1,3,...

Abstract Background and Hypothesis Environmental stressors may influence immune surveillance in B lymphocytes stimulate autoimmune responses via epigenetic DNA methylation modifications schizophrenia (SCZ). Study Design A total of 2722 Chinese Han origin subjects were recruited this study (2005-2011), which including a discovery follow-up cohort with 40 remitters SCZ (RSCZ), non-remitters (NRSC...

The gag membrane protein gP85gag, encoded by Moloney murine leukemia virus (M-MLV), was identified as a target molecule recognized by Moloney murine sarcoma virus--M-MLV (M-MSV--M-MLV)-specific cytolytic T lymphocyte (CTL) clones. Target cells infected with Ab-X-MLV, an M-MLV-derived mutant virus not encoding gP85gag, were not lysed by the CTL clones. The same CTL clones were shown previously t...

We use mathematical models to study the relationship between HIV and the immune system during the natural course of infection and in the context of different antiviral treatment regimes. The models suggest that an efficient cytotoxic T lymphocyte (CTL) memory response is required to control the virus. We define CTL memory as long-term persistence of CTL precursors in the absence of antigen. Inf...

Human immunodeficiency virus type 1 (HIV-1) Env-, Gag-, Pol-, Nef-, and Tat-specific cytotoxic T-lymphocyte (CTL) activities were quantitated temporally in five patients with symptomatic primary HIV-1 infection. A dominant CD8(+)-mediated, major histocompatibility complex class I-restricted CTL response to the HIV-1 envelope glycoprotein, gp160, was noted in four of the five patients studied. T...

Immune responses of cytotoxic T lymphocytes (CTLs) are implicated in viral eradication and the pathogenesis of hepatitis C. Weak CTL response against hepatitis C virus (HCV) may lead to a persistent infection. HCV infection impairs the function of HCV-specific CTLs; HCV proteins are thought to actively suppress host immune responses, including CTLs. Induction of a strong HCV-specific CTL respon...

Infection of C57BL/6 mice with lymphocytic choriomeningitis virus (LCMV) stimulates major histocompatibility complex class I-restricted cytotoxic T cells (CTLs), which normally resolve the infection. Three peptide epitopes derived from LCMV have been shown to bind the mouse class I molecule H-2 Db and to stimulate CTL responses in LCMV-infected mice. This report describes the identity and abund...

Generation of CTL immunity often depends on the availability of CD4 T cell help. In this report, we show that CTL responses induced by cross-priming can be converted from CD4-dependent to CD4-independent by increasing the frequency of CTL precursors. In the absence of CD4 T cells, high numbers of CTL precursors were able to expand in number and become effector CTL. The ability of high frequenci...
