The street value of prescription medications have steadily increased and the ease of getting prescription medications have also increased due to generic low cost alternatives. For example, take Xanax. One can acquire a bottle of generic Xanax for approximately $4.50 from any major pharmacy in the US. Each pill has a street value of approximately $5-10 dollars. This is scary! What is more astounding is that there are so many prescriptions written each year where the bottles generally go untouched! This has become a major problem, especially in the area of pain management. One may be [more...]

New nanopore method for DNA sequencing
(Nanowerk News) Sequencing DNA could get a lot faster and cheaper and thus closer to routine use in clinical diagnostics thanks to a new method developed by a research team based at Boston University. The team has demonstrated the first use of solid state nanopores tiny holes in silicon chips that detect DNA molecules as they pass through the pore to read the identity of the four nucleotides that encode each DNA molecule. In addition, the researchers have shown the viability of a novel, more efficient method to detect single DNA molecules in nanopores. "We have employed, for the [more...]

DNA testing is now available to evaluate the contents of a stool sample, rather than relying on the imprecise method of a microscopic exam.

Since DNA parasite analysis became available just over a year ago, it has shown to be an extremely valuable tool for helping to identify parasite infections seen in patients at the IBS Treatment Center. As a matter of practice we have always tested patients for parasites, but prior to the availability of DNA parasite testing, parasites were rarely diagnosed. DNA testing is [more...]

To harness this powerful single-molecule detection modality for high-throughput DNA sequencing, each of the four nucleotides (A, C, G and T) in the target DNA has to be converted into a predefined sequence of oligonucleotides, using a technique called Circular DNA Conversion. Each pre-defined sequence is then hybridized to a self-quenching molecular beacon. In their experimental setup, the Meller team recorded DNA translocation through a 4 nm pore in a SiN membrane immersed between two aqueous solutions. With the camera in place, the researchers were able to detect fluorescence bursts in two [more...]

There is a DNA probe recently approved to detect Mycobacterium paratuberculosis in bovine feces. Fecal culture has been the standard test used; it can demonstrate and quantify the presence of the bacteria and, therefore, identify the shedding animal. It is, however, time consuming, expensive to perform, and not widely available. In cattle, cultures usually need to be incubated eight to 16 weeks before growth of the organism is evident. Further-more, animals must be shedding bacteria to be detected. Only a very small proportion of the young stock may be shedding bacteria, and some older [more...]

Harvard-MIT study examines Graphene | UWIRE
Pore length is crucial when identifying individual DNA bases, Branton said, adding that the study “represents the first time that a molecule—DNA in our case—has been put through a nanopore that is extremely short.” Scientists in the past have studied protein-based nanopores that span five to 10 nanometers in length. But because the distance between two bases in a DNA molecule is 0.5 nanometers, such pores are ineffective, as they obstruct the resolution of 10 to 15 bases at a time. In contrast, graphene nanopores—which span a length of 0.5 nanometers—allow a single base to occupy [more...]

Raising The Alarm When DNA Goes Bad | Discuss Cancer
Histones play a major role in assembling chromatin and keeping it together, but they don’t usually have macrodomains,” says Ladurner. “The finding is particularly relevant, because it turns out that cancer cells don’t have macroH2A1.1. The fact that one member of the rapid response team that detects DNA damage is missing could contribute to the disease.” Because macroH2A1.1 is embedded in chromatin, when it recognises PAR at DNA damage sites, it drags the complex but highly-organised tangle of chromatin with it. As a result, macroH2A1.1 condenses the chromatin environment around the [more...]

Kinked nanopores slow DNA passage for easier sequencing
(Nanowerk News) In an innovation critical to improved DNA sequencing, a markedly slower transmission of DNA through nanopores has been achieved by a team led by Sandia National Laboratories researchers. Solid-state nanopores sculpted from silicon dioxide are generally straight, tiny tunnels more than a thousand times smaller than the diameter of a human hair. They are used as sensors to detect and characterize DNA, RNA and proteins. But these materials shoot through such holes so rapidly that sequencing the DNA passing through them, for example, is a problem. In a paper published this week [more...]
