  • IMAGE QUALITY IMPROVING DEVICE AND METHOD
    Publication number: 20110267540
    Abstract: A Gaussian filter 2 having a first cutoff frequency extracts a low frequency component signal of a video signal. A subtracter 3 extracts a high frequency component signal by subtracting the low frequency component signal from the video signal. A low pass filter 5 having a second cutoff frequency higher than the first cutoff frequency extracts a lower high frequency component signal, which is a low-frequency-side signal of the high frequency component signal. A multiplier 6 generates a corrected component signal by multiplying the lower high frequency component signal by a predetermined gain G1. An adder 7 adds the corrected component signal to the video signal.

  • Renal growth promoter and process for the production of the same
    Patent number: 5055554
    Abstract: The present invention relates to a renal growth promoter based on the finding that luteinizing hormone or an isoform thereof has an effect of promoting renal growth.It was previnsly unknown that luteinizing hormone or an isoform thereof has an effect of promoting renal growth.With the present invention, it is expected that kidneys suffering from a decreased in the number of renal cells or a lowering in the renal function may be activated by administering luteinizing hormone or an isoform thereof.

  • Sialic acid derivative and process for preparing the same
    Patent number: 4691012
    Abstract: A novel N-acetylneuraminic acid derivative, represented by the general formula: ##STR1## wherein the R.sup.1 groups are, independently, hydrogen or acetyl; R.sup.2 is a nucleoside residue; and R.sup.3 is carboxyl or methoxycarbonyl.The N-acetylneuraminic acid derivative is useful in inhibiting metastasis of cancer cells. Also provided is a process for the preparation of the derivatives.

  • N-Acetylneuraminic acid derivatives and the preparation thereof
    Patent number: 4447600
    Abstract: Nucleoside or glucose derivatives of N-acetylneuraminic acids are provided, which have immunological activity, are clinically useful, as an immuno suppressive, in particular to treat autoimmune disease such as collagenosis disease without causing any serious side-effects and may be prepared by subjecting a halide of N-acetylneuraminate derivative together with a nucleoside or a glucose to Koenigs-Knorr reaction.
