How to steer a moving cell

...exity of signaling mechanisms within the cell that become de-regulated and allow cells which are usually static to begin migrating. The researchers hope to fully define the protein components of the compass to gain a better understanding of what directs cell migration or, in the case of cancer cells an...

Students invent protective pouch to enhance cell therapy

...jected into the gap between the stents, where they become trapped within the nylon mesh. Blood flowing through the vessel should nourish the encapsulated cells and circulate the proteins, such as insulin, produced by these cells. The project is important because it could lead to better results from cellu...

UQ research heralds vaccine technology breakthrough

...ecoming available in the clinic. He hoped it would become one of the vaccines given to all infants in their first three months of life. The mature paediatric market for an RSV vaccine has been estimated at approximately US$800 million (LeadDiscovery Ltd, 2004). Professor Tindle said the importance of th...

New Brandeis research sheds light on memory by erasing it

...s like epilepsy, which involves synapses that have become overly strengthened. The new research shows how synapses can be weakened by attacking memory molecules. Lisman's lab plans further research to better understand what happens to the CaMKII after it is attacked. By using fluorescent forms of CaMKII...

Double the death rate from cirrhosis for 'blue collar' men

...fessor Najman said. "In Australia, alcohol has become relatively cheaper and more available. "It is already known that socio-economic inequalities in alcohol-related diseases are among the largest of any cause of death. For example, in Britain, between 1991 and 1993, liver cirrhosis rates among unsk...

DNA repair proteins monitored at double-strand break

...can move to the double-strand break, it must first become activated so it can trigger a critical series of signals linked to DNA repair. Inactive ATM exists as a pair of these molecules linked together. Kastan previously reported in the journal Nature how the inactive ATM molecules separate from each other ...

Confirmed -- deforestation plays critical climate change role

...rough to the end of the century, although they may become less efficient at higher temperatures. "The new body of information shows considerable value in preserving tropical forests such as those in the Amazon and Indonesia as carbon sinks, that they do not release the carbon back into the atmosphere as ...

Researchers develop way to calculate speed of bacterial sex

...erial into the recipient, causing the recipient to become a donor. The controlling rates of conjugative gene transfer and the kinetics of conjugative gene transfer are unknown. The study of conjugative gene transfer centers on biofilms, a coat formed by colonizing bacterial cells. "While scientists...

Spreading viruses as we breathe

...here is a risk that people can inhale that air and become infected." Professor Morawska said a droplet drying on a surface could be infectious but the greater danger was droplets drying in the air. "A droplet can travel for 10cm before it dries in the air, it doesn't immediately fall to the ground." ...

Effect on breast tumors of DNA alternations in 3 genes described

... identified specific genes that are most likely to become cancer promoters when exposed to a process called DNA promoter hypermethylation. Hypermethylation is a process that causes genes that promote normal cell growth to produce proteins that cause malignant behavior, or unregulated cell growth. Until now...

The quest for an effective HIV vaccine presents new possibilities, challenges

...s HIV infection by clearing the virus before cells become latently infected remains the goal. In addition, they believe that even a vaccine that does not prevent infection could prove beneficial if it prolongs the disease-free period and possibly even reduces virus transmission. If such a vaccine is shown t...

Better health twice as likely for nonsmokers who live and work with smoking restrictions

Latent memory of cells comes to life

...a yeast cell which was bi-stable, in that it could become either of a single sex or hermaphrodite. The experiment showed that a spontaneous change occurred in the yeast cells about every 2000 cell-generations. By building a mathematical model based on positive feedback from the microscopic state of the nuc...

Peanut allergies overstated, study finds

... requiring all sorts of restrictions, families can become very anxious when in fact, some of these families may be worrying unnecessarily," Dr Wainstein said. The study, published in the journal Pediatric Allergy and Immunology, involved 84 children with a positive result to a peanut skin-prick-test. ...

Hives ferment a yeasty brew, attract beetle pest

...ones. The first tests showed that when worker bees become alarmed, they produce from 1,500 to 10,000 times more IPA than found in an undisturbed hive. Next the researchers used a gas-chromatagraph-electroantennogram to analyze the chemical sensitively of the insects' antennae. They report in a recent online...
