Scientists create dual-modality microbeads to improve identification of disease biomarkers

... After 15-20 minutes, the butanol is removed to get rid of any remaining nanoparticles that didn’t get incorporated into the beads and the beads are washed with ethanol. Then the beads are coated with a ...

Scientists discover a new risk factor for Alzheimer's

...1 expression--in either cell cultures or mice--you get an increase in the production of amyloid-beta. Now we can add our new observation that variants of the SORL1 gene are associated with an increased risk of Alzheimer's." St George Hyslop said that other researchers need to replicate the results in o...

Birth rate, competition are major players in hominid extinctions

...dator, modern humans would eat anything they could get their hands on. They eked out a living even if it meant eating grasshoppers or whatever," says Jablonski. "Even with this, modern humans barely hung on from 12 to 16,000 years ago. "Why did Neandertal not adapt culturally?" she asks. "Why did ...

Freeze! Scientists film proteins at work by freezing them at different states

...ments until today were restricted to proteins that get excited by light and are in very resistant crystals....

Jefferson researchers' discovery may change thinking on how viruses invade the brain

...es to the cellular transport machinery in order to get there. But Dr. Schnell and his co-workers found that this protein complex is instead a "transcription factor" that plays a role in virus reproduction. "We think that this finding has implications not only for rabies but many viruses that previou...

Lead with a poisonous electron shield

...storted and inefficient; the three remaining sites get a reduced efficiency. d-Aminolevulinic acid dehydratase is essential for the biosynthesis of hemoglobin. Inhibition of this enzyme disrupts the formation of blood to the point of anemia. At the active center, a zinc ion binds to four ligands, thre...

Small molecule dervived from Rb2/p130 could act as cancer therapeutic

...For these reasons, he believes it may be easier to get approval for clinical trials. "Fifteen years after discovering Rb2/p130, our research and hard work has led us to the discovery of this small molecule, which is a step forward in cancer research and a big step toward a cancer treatment," he said. ...

New bird, bat species revealed by extensive DNA barcode studies

...in different ecological niches, cancer is tough to get rid of. The former University of Alberta biologist has been working with DNA ?the molecule that carries our cells?genetic information ?ever since 1947, six years before its structure was described by Watson and Crick. His fundamental Natural Scienc...

Health Canada approves cold and flu medicine

...a cold or the flu in the first place, or if you do get one, to fight it more effectively." The NHPD’s safety review confirmed the safety profile of COLD-fX with no known side effects or drug interactions for generally healthy individuals. Health Canada established new regulations effective Jan. 1, ...

Long-lived deep-sea fishes imperiled by technology, overfishing

... we need to know more about is how the fish larvae get transported," Heppell said. "We don't know whether fish from different seamounts are genetically distinct or whether larvae from one seamount end up populating another. The odds against these fish are so high that, in a reproductive sense, they have ...

Batten down the hatches against HIV

...ection, as previous work have shown. But how to get the RNA fragments into the T-cells? The shells of nonpathogenic viruses can be used to smuggle genetic material into cells, but this is dangerous in therapeutic applications because they can trigger allergies. Liposomes, tiny bubbles of fat, are safe...

Bird sex is something else

...d sex chromosomes (X and Y in humans, for example) get around the fact that males and females get different-sized portions of sex chromosome genes with a balancing act geneticists call dosage compen...

Can engineered immune cells stop AIDS?

... to manipulate these elusive bone marrow cells and get them to generate "designer immune cells." Another problem seems to be making sure lentiviral vectors target only hematopoietic stem cells, and not other types of cells, to achieve the desired targeted delivery. With a group of USC biomedical engin...

Speeding 'fingertip' discovery -- 20 years of protein info in 1 place

Protein key to organ growth

...hat in the case of dysfunction, the eyes and wings get smaller," said Choi. "If you completely knock out this function in the eye, they have no eyes." TCTP was of interest because it is over-expressed or overabundant in cancer cells. "If you reduce the levels of TCTP, tumor cells revert to normal ...

Natural polyester makes new sutures stronger, safer

...type of suture based on MIT research, patients who get stitches may never need to have them removed. A biopolymer suture cleared last month by the FDA is made of materials that the human body produces naturally, so they can be safely absorbed once the wound is healed. They are also 30 percent stronger t...

Gene hunters close in on Lou Gehrig’s disease

... “If you roll dice 555,352 times, you are bound to get lucky by chance alone on some of those throws,?he says. “The next step is to go back and figure out which of these ‘hits?are real and which are false.? Thousands of other SNPs were more weakly associated with ALS, some of which could turn out to b...

Study of planarians offers insight into germ cell development

...logical tools available for studying planarians to get at the mechanisms that tell a cell: ‘You’re going to be a germ cell.?" S. mediterranea also has the ability to reproduce asexually: It clones itself by means of fission. In looking at nanos in asexual individuals of this species, the researchers m...
