What does a chromoendoscopy mean?
What does a chromoendoscopy mean? This Chromoendoscopy helps visualize the inner surface of the bowel (epithelia) during endoscopy. A chromoendoscopy is a diagnostic procedure in which a chemical substance (called a stain or pigment) is sprayed inside the gut to highlight specific areas or distinguish among the different types of cell layers.
What is the pathophysiology of chromoplexy?
Chromoplexy refers to a class of complex DNA rearrangement observed in the genomes of cancer cells. This phenomenon was first identified in prostate cancer by whole genome sequencing of prostate tumors.
What is Chromo-photography?
The term "Chromo-photography" was also used to describe a very different photographic technique using chromic acid described in Dr. Hermann Wilhelm Vogel 's book The Chemistry of Light and Photography as reviewed in The Examiner of 24 July 1875.
How Does Chromotherapy Work?
Chromotherapy relies on the concept that different colors of light vibrate slightly differently. This makes intuitive sense as different colors are, after all, merely different wave forms of photons that vibrate or reflect off surfaces in unique ways.
What color is used in chromotherapy?
Red and other colors used in chromotherapy can potentially boost blood circulation throughout the body. As blood circulation improves, tissues throughout the body receive more oxygen and vital nutrients, potentially accelerating the healing process and improving wellness across the board.
Can chromotherapy be done with different colors?
The exact benefits of certain colors during a chromotherapy session can vary from person to person. But in general, the below effects are typically associated with different concentrated colors of light.
Is green a good color for mental health?
Green. Many people find green to be a harmonious color. As a result, it can provide mental health benefits and calm you down at the end of a long, stressful day
Does chromotherapy help with pain?
Some individuals experience pain relief during and after a chromotherapy session. Specifically, they may experience decreased inflammation and less swelling of injured tissues, especially for chronic conditions like arthritis. It’s thought that certain colors of light can help to relax the muscles and, therefore, relieve many symptoms of inflammation .
What is chromoplexy in biology?
Chromoplexy has been proposed as a means by which cancer genomes may undergo bursts of evolution by altering multiple cancer genes across the genome in a single “hit”. For example, in at least one prostate tumor, a single chromoplectic event generated the TMPRSS2-ERG fusion while inactivating other tumor suppressor genes such as SMAD4 .
How many chromosomes are involved in chromoplexy?
Chromoplexy often involve segments of DNA from multiple chromosomes (e.g., five or more), while chromothripsis usually involves clustered regions of one or two chromosomes. A single instance of chromoplexy often involves fewer rearrangements than the hundreds described in chromothripsis.
What is the mechanism of complex rearrangements in chromoplexy?
A proposed model is that DNA is brought together in nuclear transcription hubs where genes across multiple chromosomes are co-regulated by transcription factors such as the Androgen receptor. This DNA may then sustain multiple transient breaks during transcription and sets of broken DNA ends may be ligated to one another in an incorrect configuration.
What is the term for a class of DNA rearrangement observed in the genomes of cancer cells?
Chromoplexy. Chromoplexy refers to a class of complex DNA rearrangement observed in the genomes of cancer cells. This phenomenon was first identified in prostate cancer by whole genome sequencing of prostate tumors.

Is chromoplexy the same as chromothripsis?
Chromoplexy is similar to, but distinct from chromothripsis, a phenomenon whereby a single catastrophic event causes “shattering” of a chromosome:. The precise delineation between chromothripsis and chromoplexy is unclear, however general distinctions are
Can chromoplexy occur in multiple rounds?
However, “deletion bridges” may be seen in chromoplexy that represent lost DNA at the fusion junctions of rearrangements. In at least some instances of prostate cancer, chromoplexy can occur in multiple subsequent rounds. In contrast, multiple independent chromothripsis events have not been identified in single tumors.
How many stones are used in a chromolithograph?
A chromolithograph is made using anywhere from eight to forty stones, one for each color. The chromist, who specialized in breaking down the colors needed to re-create the painting in ink, would document this process in a progressive proof book, so that the image could be recreated easily again if needed. The American Antiquarian Society has seven of Prang’s progressive proof books, including a published version where the process of creating a chromolithograph is explained for the use of salesmen. Seen here, Prang explains the process in creating one of his best-selling prints, Prize babies.
How are lithographs created?
Lithographs were created by drawing an image onto a smooth stone, usually limestone, treated with chemicals, and then printed on paper. Color lithography, different than a true chromolithograph, took a lithographic drawing done in black outline, and was filled in with colors produced on different stones.
What is lithographic stone?
The lithographic stone, which is an amorphous limestone, dense in texture whitout being hard, … [and] has a great affinity for fat. …. The drawing on the stone is made with the lithographic crayon, consisting of soap, wax and lampblack, …. The drawing, when finished, undergoes an operation called technically ‘the preparation.’.
What is chromophotography?
Chromophotography is a technique, somewhere between painting and photography, which evolved in the second half of the 19th century. Firstly, two prints of the photograph were made. One was hand-painted with very bright colours; the other was painted in paler colours, and then made translucent by applying wax to the paper.
Who invented chromo photography?
This pre-dates by 8 years the first reference to the new invention called "chromo-photography" by M. Albert, photographer to the Court in Munich reported in the South London Chronicle of 10 May 1862.
How is the top layer of a chromophotograph made?
The top layer of the chromophotograph has been made translucent by treating the paper with wax. Either salt or albumen paper may have been used for this top layer. The colouring on the top layer is not typical for chromophotographs by other photographers. The chromophotograph was originally mounted in a decorative frame, with an oval mask.
Who was the first photographer to use chromo photography?
In New Zealand, Gisborne photographer C. P. Browne advertised Chromo Photography in 1883. However, the word chromophotography was used in several different ways during the 19th century and it cannot be assumed that a reference automatically refers to the technique described here.
Who was the photographer who was known for taking life-like CdVs in natural colors?
The Bucks Free Press of 2 September 1870 carried an advertisement by the photographer Laz Roberts which said "he is working on entirely new process of his own, Chromophotography, and taking life-like CdVs in Natural Colours", but it is not certain what technique he was using.
What is chromoendoscopy?
Chromoendoscopy is a modified gastrointestinal (GI) endoscopy procedure that uses stains, pigments or dyes to locate cancerous spots in the lining (mucosa) of your digestive tract.
Types of Stains Used in Chromoendoscopy
The doctor may treat the lining of your GI tract with different stains that interact in unique ways with the lining of your digestive tract. Each type of stain serves a different purpose:
Who may need chromoendoscopy?
Chromoendoscopy can be used to examine the GI tract anywhere along its length. Your doctor may recommend this procedure if you have precancerous conditions or you are at high risk for cancer because of genetic or environmental factors. Chromoendoscopy might be appropriate if you have a higher-than-normal risk for GI cancer due to:
Preparing for Chromoendoscopy
Chromoendoscopy can be part of an upper GI endoscopy or a colonoscopy, so your preparation will depend on which of these tests you are undergoing.
What Happens During Chromoendoscopy
During your upper GI endoscopy or colonoscopy, a gastroenterologist will use the endoscope with a special catheter attachment to spray a dye or stain onto the inside of your GI tract and observe any areas that react differently to the substance. The doctor may remove a sample of tissue from an area to look at it under a microscope (biopsy).
Risks of Chromoendoscopy
Aside from the slight risk of side effects associated with upper GI endoscopy or colonoscopy, the spraying of the dye or stain on the inside of your digestive tract is safe.
Recovery After a Chromoendoscopy
Follow your doctor’s instructions if you have had a biopsy or other treatment along with the chromoendoscopy. For the most part, once the tests are complete, you can be driven home and rest for the remainder of the day while the sedating medicine wears off. The following day, you likely can resume your regular activities.
