Feedback from Interpol DNA User's Conference | DNA Project - South ...

This time last week I was sitting at the Interpol Headquarters in Lyon, France listening to the Chief of the USA FBI CODIS Unit talk about International DNA Exchange methods. This was only one of approximately 35 fascinating presentations delivered by representatives from over 50 countries. As you may well imagine, participating in a conference of this magnitude was extraordinary, and the value of being able to interact with the other representatives: priceless. A special mention of thanks needs to go to our generous sponsor, The Open Society Foundation for South Africa, which enabled us to [more...]

Celebrity Feetwin » Genetic link to migraines discovered by ...

They looked at the DNA of 110 people with migraine and members of their family, and found that TRESK was a major component in migraines. One of the Oxford researchers, consultant neurologist Zameel Cader, described it as a “once in a generation find” and said that it could “potentially lead to a treatment for pain in general.” Before this study, no genes had been directly linked to migraines, although parts of the DNA that raised the general risk had been found. Migraines are described by the World Health Organisation as a major worldwide cause of disability. In Britain, it is [more...]

Searching for cellular switches

As he “engaged science further” as an undergraduate at the University of California, San Diego, he began to appreciate how those basic atoms and molecules came together to create the building blocks of life, such as DNA, RNA and the proteins that control the body."Understanding these basic components of life made me want to further explore how biology, chemistry and physics met at a molecular interface within cells," Buchler said. He first chose to focus on physics then directed his studies more toward biology and theory as a doctoral student at the University of Michigan in Ann [more...]

Good Idea: JonBenet Ramsey's Case Re-Opened After 14 Years | FIRETOWN!

In 2008 – two years after Mrs Ramsey’s death from cancer – the Boulder County district attorney told the Ramseys they had been exonerated by the discovery of DNA traces of an unidentified male on the pyjamas worn by JonBenet on the night she died. Prosecutors said the DNA was not from the Ramsey family and was almost definitely that of the killer. Mark Beckner, Boulder’s police chief, would not comment on the investigation. ‘We continue to work the Ramsey case. This has included additional contacts and interviews with those who may have information pertinent to the case,’ he [more...]

However, the function of chromatin diminution remains a mystery, because the vast majority of the eliminated DNA is noncoding. Within the parasitic roundworm genus Strongyloides, S. stercoralis (in man) and S. ratti (in rat) employ XX/XO sex determination, but the situation in S. papillosus (in sheep) is different but controversial. Results We demonstrate genetically that S. papillosus employs sex-specific chromatin diminution to eliminate an internal portion of one of the two homologs of one chromosome pair in males. Contrary to ascarids, the eliminated DNA in S. papillosus contains a large [more...]

Bartonella Co-infection Epidemic Helps Spread Lyme Disease ...

As researchers have continued to study these bacteria, we’ve learned that the intraerythrocytic component of the infection with a Bartonella species has been somewhat overemphasized… Bartonella species are endotheliotropic bacteria that use a specialized invasion process to enter endothelial cells and can move about the body by infecting macrophages, with localization in a variety of tissues…3 Researchers have learned that Bartonella species are the first bacteria identified to have an ability to invade CD34+ progenitor cells in bone marrow.5 This may be why we find Bartonella organisms [more...]

Human Papilloma Virus and Cancers | Health news for americans

In recent years, it has become clear that certain types of human cancers have a viral component to their etiology. Cancers due to Human Papilloma Virus (HPV) are most common among these. This has been a study of intense research for number of years. Specific types of HPV genotypes were found to be the causative agents of some common cancers, most notable invasive cervical carcinoma. Apart from this anogenital cancer, HPV’s are also causally associated with other anogenital cancers such as cancers of vulva, vagina, penis and anus. HPV is also responsible for approximately 20-30% of head and [more...]

How does Haelan work? | WeeksMD

Restores Cell Differentiation – Carcinogens damage DNA daily. Fortunately this daily attack is tolerated by most people most of the time since chromosomes usually repair the damage within a fifteen minute time period. However, if the cellular damage is so great that it interferes with the chromosomal DNA repair process, the cell DNA damage is not repaired. It has been scientifically established that if the DNA damage is not repaired in two hours then it is unlikely to be repaired. Haelan’s isoflavones are very potent and have the ability to protect the DNA from damage in the first place [more...]

Multi-Component Nano-Structures with Tunable Optical Properties

“For the first time we have demonstrated a strategy for the assembly of 3-D, well-defined, optically active structures using DNA encoded components of different types,” said lead author Oleg Gang of Brookhaven’s Center for Functional Nanomaterials (CFN). Like earlier work by Gang and his colleagues, this technique makes use of the high specificity of binding between complementary strands of DNA to link particles together in a precise way. In the current study, the DNA linker molecules had three binding sites. The two ends of the strands were designed to bind to complementary strands on [more...]

Created in 2006 at JTA's request, it is now independent. Tracing the Tribe readers may remember several posts concerning a cluster of "Ashkenazi" breast cancer among Hispanic women in Colorado's San Luis Valley a few years ago. Later genealogical research showed the women were descendants of conversos (Jews forced to convert to Christianity during the Inquisition) who had settled in the area centuries ago. A paper in the San Luis area just [more...]

BVT and Cancer – scientific support. | WeeksMD

Bee venom specifically suppressed the phosphorylation of p38/JNK and at the same time, suppressed the protein expression, DNA binding and promoter activity of NF-kappaB. The levels of phosphorylated ERK1/2 and c-Jun did not change. We also investigated MMP-9 inhibition by melittin, apamin and PLA(2), representative single component of bee venom. We confirmed that PMA-induced MMP-9 activity was significantly decreased by melittin, but not by apamin and phospholipase A(2). These data demonstrated that the expression of MMP-9 was abolished by melittin, the main component of bee [more...]

those that target DNA/RNA synthesis e.g. flucytosine. Mammalian cells make extensive use of DNA & RNA so this drug lacks specificity. Difficult to use. Clearly the best existing target in terms of specificity is the cell wall. In this news report it states that this research group have just announced the $1.5 million funding of new research into drugs that will act on a component of the construction of cell walls (UDP-galactopyranose mutase) in fungi with the aim of disrupting the process and thus making it very difficult for the fungus to make its own cell wall and grow normally.

Evolution News & Views: When "Junk DNA" Isn't Junk: Farewell to a ...

In the Darwinist repertoire, a standard response to evidence of design in the genome is to point to the existence of "junk DNA." What is it doing there, if purposeful design really is detectable in the history of life's development? Of course this assumes that the "junk" really is junk. That assumption has been cast increasingly into doubt. New research just out in the journal Nature Genetics finds evidence that genetic elements previously thought of as rubbish are anything but that. The research describes tiny strands of RNA, previously thought to be junk, that now turn out to play a role in [more...]

OJ Simpson Trial at 15: A Legacy of Bad DNA, Beard Strokes, Bruno …

Simpson also brought in Barry Scheck (pictured below) and Peter Neufeld, the two most-knowledgeable attorneys on the planet regarding DNA evidence, which became a critical component — and arguably the most important legal legacy — of the trial. There was certainly no shortage of circumstantial evidence connecting Simpson to the murders. He had a long history of abusing his ex-wife, a point the prosecution drilled home in their opening statement by playing a frantic 911 call made by Mrs. Simpson, five years before the murders, when an enraged O.J. was banging on her door. The case ignited [more...]
