Detection of chromosoal abnormalities associated with breast cancer

Disclosed are new methods comprising the use of in situ hybridization to detect abnormal nucleic acid sequence copy numbers in one or more genomes wherein repetitive sequences that bind to multiple loci in a reference chromosome spread are either substantially removed and / or their hybridization signals suppressed. The invention termed Comparative Genomic Hybridization (CGH) provides for methods of determining the relative number of copies of nucleic acid sequences in one or more subject genomes or portions thereof (for example, a tumor cell) as a function of the location of those sequences in a reference genome (for example, a normal human genome). The intensity(ies) of the signals from each labeled subject nucleic acid and / or the differences in the ratios between different signals from the labeled subject nucleic acid sequences are compared to determine the relative copy numbers of the nucleic acid sequences in the one or more subject genomes as a function of position along the reference chromosome spread. Amplifications, duplications and / or deletions in the subject genome(s) can be detected. Also provided is a method of determining the absolute copy numbers of substantially all RNA or DNA sequences in subject cell(s) or cell population(s).

Electromagnetic fields for systemic effect in therapy

A new mechanism of therapeutic action of electromagnetic fields, based upon systemic effect, applies selected EMF signals to cause efficacious therapeutic effects at sites distant from the point of application. The method of generating specific EMF waveshape and application of this exogeneous signal for therapeutic purposes allows the benefit to be achieved via the systemic effect. The EMF signals take the form of a repetitive sequence of semi sinewaves, resulting in a pulsating waveform occurring at a frequency in the range of from about 50 to about 300 pulses per second. Bridge rectification is applied to a sinusoidal signal, and a resultant therapy signal takes the form of a repetitive sequence of semi sinewaves of up to about 300 pps with a periodically recurring DC component. The shape of alternating pulses in the resultant therapy signal is modified under computer control to achieve therapeutic effects. Flux densities in the range of several hundred Gauss up to several thousand Gauss are generated. The treatment with the resultant therapy signal may be applied to an arm or leg of a therapy recipient for a sufficient length of time to cause the recipient's entire blood volume to be exposed to the therapeutic field such that this can initiate effects in cells, tissues, and organs distant from the point of application

FISH (fluorescence in situ hybridization) probe, kit and detection method for detecting BCR/ABL fusion gene free from repetitive sequence

The invention belongs to the field of biotechnology, and discloses a FISH (fluorescence in situ hybridization) probe, a kit and a detection method for detecting BCR / ABL fusion gene free from repetitive sequence. A BCR gene and ABL gene are used as templates to perform polymerase chain reaction on non-repetitive sequence in the BCR gene and ABL gene, the amplification product is DNA (deoxyribonucleic acid) fragments with 350-800 different base-pairs, the repetitive sequences in the BCR gene and ABL gene are eliminated so as to form the product free from repetitive sequence; after the product is in fluorescence labeling, the BCR gene and ABL gene free from repetitive FISH are obtained for the BCR gene and ABL gene FISH detection. The BCR / ABL fusion gene FISH probe obtained by the invention can be used for eliminating the repetitive sequence, the non-specific background signal of the FISH probe can be obviously reduced, and the specificity of the FISH probe is improved.

Optical filter

An optical filter has a multilayer thin film comprising first to i-th layers stacked in alternate layers of high and low refractive indices on a transparent substrate. Respective odd-numbered layers (Sigh refractive index layers) and respective even-numbered layers (low refractive index layers) form repetitive sequences of layers each of which cyclically changes in optical thickness throughout the multilayer tin film. Each of k-th from-the-bottom alternate layers of high and low refractive indices has such an optical thicknesses as meet the following conditional expressions (1) and (2), concurrently:n×d=(.c / 4)×[1+sin{(k−1)×}×.]  (1)0 . . . <1   (2)where.c is the center wavelength of reflection band,n is the ref ion index of the layer for the d-line,d is the physical thickness of the layer,. is a factor of a pitch angle represented by 2. / the number of layers a one layer-stack,. is the rate of amplitude.

DNA electrochemical sensor based on target DNA repetitive sequence self enhancement and amplification signal

The invention discloses a DNA electrochemical sensor based on target DNA repetitive sequence self enhancement and amplification signal. A signal probe is designed by a repetitive sequence clip of a detected target chain, thus, the volume of the signal probes combined with the target sequence is increased, and a compound is formed, when a capture probe on electrode surface is hybridized with the target sequence, the amplified signal probe is combined with the electrode surface, under the affinity function between the biotin treated by end labeling of the signal probe and the avidin modified on the horseradish peroxidase, multiple enzymes are combined with a 'sandwich' structure, finally, under the efficient catalytic action of the enzymes, H2O2 is catalyzed to oxidize the TMB, the oxidative product generates an amplified reduction current signal on the electrode, and the concentration of the target DNA is judged according to the magnitude of the current signal. In the experiment, based on the characteristics of self enhancement and amplification signal of the target chain of the repetitive sequence, the target chain with two sections of repetitive sequences is detected, and the method is high in sensitivity.
