摘要： A control circuit of the power converter according to the present invention comprises a feedback circuit, an output circuit and an adaptive clamping circuit. The feedback circuit generates a feedback signal in accordance with an output of the power converter. The output circuit generates a switching signal in accordance with the feedback signal for regulating the output of the power converter. The adaptive clamping circuit limits the level of the feedback signal under a first level for a first load condition. The feedback circuit determines a slew rate of the feedback signal for increasing the level of the feedback signal from the first level to a second level. The adaptive clamping circuit is disabled and the level of the feedback signal can be increased to the second level for a second load condition.

摘要： A series of p105-based NF-κB super repressors, designated p-105(sr), have been designed. The p105(sr), no longer generates p50 and undergoes signal-induced degradation, effectively inhibiting all NF-κB activities. Additionally, p105(sr) significantly enhances tumor necrosis factor alpha (TNF-α)-mediated killing of MT1/2 skin papilloma cells when p50 homodimer activity is elevated. p105(sr) is an effective NF-κB super repressor with a broader range than other currently available IkBα super repressors. The novel repressor can be used in cells where a noncanical NF-κB activity is dominant or multiple NF-κB activities are activated.
