The present invention relates to the discovery that a secretory phospholipase A2 (sPLA2-IIA) plays an active role in mediating cellular signaling leading to an inflammatory response or cell proliferation by way of its specific binding with integrin &#x3b2; at site 2 of integrin &#x3b2;. More specifically, the invention provides a method for identifying inhibitors of inflammatory or proliferative signaling by screening for compounds that interrupt the specific binding of sPLA2 and integrin &#x3b2; at site 2. The invention also provides the novel use of a substance that suppresses the specific binding between sPLA2 and site 2 of integrin&#x3b2; for the purpose of treating or preventing a condition involving an undesired inflammatory response or cell proliferation.

Suppression of SPLA2-integrin binding for treating an inflammatory condition or suppressing cell proliferation

A video signal of an interlaced scanning system having 525 scanning lines and a vertical scanning frequency of 60 Hz is converted to a video signal having 1050 scanning lines and a vertical scanning frequency of 120 Hz, for displaying an image by bidirectional scanning. A vertical synchronizing signal is subjected to offset processing by a &frac14; horizontal scanning period when an odd field is started, thereby keeping interlaced relation between odd and even fields. The vertical synchronizing signal is subjected to offset processing by a &frac12; horizontal scanning period every frame, so that the scanning direction for each scanning line is reversed every frame.

A component of color difference signal is detected from a video component signal, and its color saturation information is compared with a predetermined threshold level, then in response to the comparison result, information is generated in order to control phase modulation such as, when the information is smaller than the threshold level, phases of color burst signals are modulated during a specified period, and when the information is larger than the threshold level, the phase stays as standard. The generated information is added to the color video signal. These steps can avoid unpleasant striped color noises appeared on a conventional color TV receiver, the unpleasant striped color noises has been caused by a modified color burst signal without the above steps.

A phase locked loop circuit comprises a divider which is changed in a dividing ratio in compliance with a control signal applied thereto, the output of the divider is phase-compared with an input signal of the phase locked loop circuit. A phase-compared output is applied to a low pass filter to obtain a direct current component, and an oscillator is controlled by the direct current component.

Phase locked loop circuit

A noise reduction apparatus for use in a television receiver or VCR using the NTSC format, in which a video signal or a demodulated color difference signal is processed by an operational circuit which supplies a noise-reduced output signal to a first one of two series-connected one-frame delay elements and which compares the input video signal with an output signal from the first 1-frame delay element, to execute noise reduction. A degree of noise reduction executed by the operational circuit is controlled in accordance with the degree of correlation between the output signal from the second 1-frame delay element and the input video signal, such that the degree of noise reduction is made small or zero when the correlation is below a predetermined level, indicating the presence of motion components in the video signal. Due to the 2-frame delay used in judging that degree of correlation, the judgement will not be adversely affected by interference components of the video signal which result from interaction between the chroma and high-frequency luminance components of the video signal, when there are no motion components in that signal.

Noise reduction apparatus for television receiver

Major adjustments of an equipment such as a television receiver are attained by remote control signals from a remote control signal transmitter provided for the equipment. A memory for storing control data for a signal processing circuit, a control circuit for controlling the signal processing circuit and the memory, and a switching circuit for setting the control circuit in a first mode or a second mode are provided. In the first mode, the signal processing circuit is controlled by the remote control signal, and in the second mode, the signal processing circuit is controlled by the same remote control signal and the resulting control data is written into the memory.

Control unit including a circuit for controlling and setting control

A circuit for detecting the presence or absence of a television receiving signal is disclosed, wherein a detection output for automatic frequency control is compared with first to fifth levels. A low-level output is produced when the detection output is lower than the fifth level; an intermediate-level output is produced when the detection output is between the fifth and fourth levels; a low-level output is produced when the detection output is between the third and second levels; an intermediate-level output is produced when the detection output is between the second and first levels; and a high-level output is produced when the detection output is higher than the first level, thus producing an output signal of three-digit level from a single output terminal.
