Who's Concerned About Celiac? | Pregnancy Info Center

The Blood Test cost can vary from $50 to $250 depending on just how much of the panel gets screened plus if Celiac DNA tests were added on the Celiac Blood Test. The Dermatitis Herpetiformis bloodstream test is performed by testing the blood for anti-gliadin, anti-reticulin and anti-endomysial antibodies which can cover much more ground in locating auto antibodies. Treatment from both Celiac Disease and DH is gluten-free eating habits which may be tough as gluten is in most of all prepared foods. The Crohn’s blood vessels check is dependant on locating unusually higher with blood vessels [more...]

Stool DNA Testing

A stool DNA test has drawn much media attention as means of knowing whether one suffers from colon cancer. There is only one stool DNA test currently one the market and although it still has not yet been approved by all the relevant authorities it is nevertheless, still a very promising test. The test has however, been championed by the American Cancer Society and other reputable associations in the field. How is a Stool DNA Test Carried out to Detect Colon Cancer? First, we may begin by explaining what the colon is and does. The colon is a part of the large intestine. Whilst the small [more...]

Mitochondrial DNA Genealogy

The mitochondrial DNA genealogy is the study of a person’s mother’s family line of maternal ancestors. This DNA is passed down from mother to each of her children exactly as she has it, with no mutations, except in the very rare instances. Because of the traditions in our society of the wife taking her husband’s last name, a surname genealogy trace of the female line of the family tree is more difficult. On the flip side, since this DNA strand is more stable than the Y DNA, more conclusive results can be determined for the testing of it. The mt-DNA is sometimes referred to as the Full [more...]

Technology Review: A Genetic Christmas Story

Some people may have received an unusual gift this holiday season: an ancestry testing kit that uses a small swab of DNA to shed light on near and ancient family history. It sounds, at first, like a novelty item. But the kit may provide long-term assistance to scientists who are hoping to track the history of the human race. In one project, spearheaded by National Geographic Society and IBM, participants buy a kit for $99.95, scrape some skin cells from the inside of their cheek, and send the samples in for analysis. Once the DNA is processed, participants learn their haplogroup -- the [more...]

Evolution News & Views: Guy Walks Into a Bar and Thinks He's a ...

Part of the reason for this is if one decides to take into account the plethora of species-specific DNA insertions and deletions ("indels") that are present along any segment compared between chimp and human, the percentage of identity drops. Another reason is that duplications, inversions, translocations, and transpositions at all scales uniquely characterize the two genome sequences -- these have to be untangled before aligning the sequences in order to measure their similarity. Also, the 99% identity figure is often derived from protein-coding regions that only comprise about 1.5% of the [more...]

TTC VIDEO – Major Transitions in Evolution

New technologies, such as DNA analysis, together with the latest fossil discoveries, make this a fast-changing subject that has grown far more detailed and complete than the presentation you may have learned in school. Among the scientific and popular misconceptions that have been overturned are these: * Neandertals: Recently sequenced DNA from Neandertals suggests that they were not an isolated throwback but contributed some genes to the modern human lineage. Genetic and other clues show that behaviorally Neandertals were very human-like. * Ardipithecus: The 2009 discovery of a relatively [more...]

Baby DNA test: Who is the father? Part II

A baby DNA test is one means of establishing with certainty who the daddy of the unborn child is. One can of course choose to wait till after the child is born although it is important to know that this is not necessary as a paternity test can be conclusively carried out while the mother is still pregnant. How is the Baby DNA testing done? There are two main methods through which the unborn baby’s DNA can be sampled. Amniocentesis: this is carried out anywhere between week 14 and week 20 of the pregnancy and is normally done as a routine procedure to locate abnormalities in the chromosomes. [more...]

Further, structural DNA nanotechnology, particularly scaffolded DNA origami, has been proposed to provide frameworks for use in nanotechnology to spatially organize functional components (see, for example “Modular DNA nanotubes provide programmable scaffolds for nanotechnology” and “Advancing nanotechnology by organizing functional components on addressable DNA scaffolds“. Now, these two threads, mechanical control of chemical reactions and DNA nanotechnology have been brought together.

Combined genital HIV (RNA and DNA) was detected at 49.2% of study visits and was associated with an elevated concentration of cervical white blood cell infiltrate (odds ratio, 2.52 ; ). Infiltrate was not associated with a clinical disorder or patient‐reported symptoms. Conclusions.  Despite antiretroviral therapy adherence and clinically suppressed plasma viremia, HIV was intermittently detected in genital secretions and was associated with [more...]

Prayerful Night!

Last week we had a wonderful time in cell. We eat, share and PRAY for one another! "So I say to you: Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. For everyone who asks receives; he who seeks finds; and to him who knocks, the door will be opened. "Which of you fathers, if your son asks for a fish, will give him a snake instead? Or if he asks for an egg, will give him a scorpion? If you then, though you are evil, know how to give good gifts to your children, how much more will your Father in heaven give the Holy Spirit to those who ask him!" [more...]

DNA repair causes damage - The Scientist - Magazine of the Life ...

A supposedly accurate DNA repair mechanism employed by cells to fix double-strand breaks can surprisingly increase the nearby mutation rate by up to 1400 times, providing a possible explanation for the accumulation of tumor-causing mutations in cancerous tissues. Previously, "we saw that DNA breaks are present in precancerous legions," said molecular oncologist Thanos Halazonetis of the University of Geneva, who did not participate in the research. "These breaks, based on this finding now, could perhaps explain mutations in oncogenes that drive cancer progression." Cancer [more...]

DNA art imitates life: Construction of a nanoscale Mobius strip

The circulations of earth's warmer and cooler ocean currents for example, describe a Möbius shape. Other topological structures are common to biological systems, particularly in the case of DNA, the 3 billion chemical bases of which are packed by the chromosome inside the cell, using topological structures. "In bacteria, plasmid DNA is wound into a supercoil," Yan explains. "Then the enzymes can come in and cut and reconfigure the topology to relieve the torsion in the supercoil so that all the other cellular machinery can have access to the gene for replication, transcription and so [more...]
