Botox could help target resistant tumors for treatment

...lls in proximity to the tumor. "This is the first experimental model demonstrating how Botox can affect the reaction of blood vessels that feed tumors," said Gallez. "Tumor microvessels are formed hastily, and lack smooth muscle layers, but one can find mature blood vessels, with smooth muscle layers that respon...

Watching the brain switch off 'self'

...basic nature of consciousness and perception. The experimental challenge that the researchers faced was to design one task that could be used to activate specifically either sensory processing or introspection brain areas. Their solution was to ask subjects to look at the same pictures or listen to the same musi...

Absence of critical protein linked to infertility

...ng, who created mice that lacked the protein. The experimental mice were then used to observe the relationships of the hormones and their receptors with the protein under varying conditions during the critical implantation period. In doing so, researchers determined that C/EBPb is a critical mediator of steroid ...

Forsyth scientists gain greater understanding of how embryos differentiate left from right

...ology, http://www.cellregeneration.org/ . Through experimental approaches and mathematical modeling, Dr. Levin and his team examine the processes governing large-scale pattern formation and biological information storage during animal embryogenesis. The lab's investigations are directed toward understanding the...

Rare Chinese frogs communicate by means of ultrasonic sound

...ranges. They observed eight male frogs under three experimental conditions (no sounds, playback of calls containing only audible parts and playback of just ultrasonic frog calls). During playback, the researchers watched for evoked calling activity in which a male frog begins calling upon hearing calls from othe...

Stanford/Packard scientist's data-mining technique strikes genetic gold

...me in diseased and healthy cells, or in many other experimental conditions. Each experiment generates thousands of pieces of data about the cell's genes. Although biologists use the technology routinely, focusing only on the few results pertinent to their particular research topic, most scientific journals requir...

USC, Rice to develop bacteria-powered fuel cells

...computational modeling, Lüttge will contribute his experimental skills in an imaging technique called Vertical Scanning Interferometry. The technique, which he helped create in the 1990s, combines information from multiple beams of light to resolve sample features as small as one-billionth of a meter. In previous...

Researchers identify new cord blood stem cell

...cord blood stem cells into laboratory rodents with experimental strokes resulted in significant reductions in the size of brain lesion, and improved these animals' use of their limbs. Some of the transplanted stem cells developed into "neuron-like" cells that are typically found in the brain. In addition, the ...

Cracking the genetic code for control of gene expression

...ression of a marker gene in transgenic mice. Novel experimental and computational methods enabled genome-wide analysis of regulatory elements in several species. Studying the control of gene expression is a growing area of research at the moment, likely owing to its fundamental importance to many biological pro...

UCLA scientists uncover mechanism of response to targeted therapy

...set of kidney cancer patients responded well to an experimental targeted therapy, but they didn't know why. If the...s in a subset of patients became sensitized to the experimental drug CCI-779. Armed with this information, UCLA researchers are developing a test to identify which ...

How can we protect patients with weakened immune systems from influenza?

...row) and patients with ovarian cancer receiving an experimental treatment--an anti-cancer vaccine made from dendritic cells. Carl June, M.D., director of translational research at Penn's Abramson Cancer Center, leads both projects. A third group of adult patients suffers from autoimmune diseases, those in which...

Research could lead to better drugs and whiter whites

... a large interdisciplinary group based on detailed experimental observations and theoretical analysis at the atomic level," said Professor Scrutton, who is based in the University's Faculty of Life Sciences. "Modern drugs are designed to have structures that stick to enzymes and prevent them from catalysing the ...

Strawberries by design

...is the result of innovation and great attention to experimental detail." Due to the small size of its genome, short reproductive cycle and small plant size, F. vesca is an ideal model system for genomics in commercial strawberry. The rapid growth of new shoots, the high number of seeds generated and the ease in...

MBL leads effort to update E. coli genome

...ach E. coli K-12 product based on previously known experimental evidence or sequence analysis. "We cooperated to an amazing extent, reviewing every single one of 4,500 genes of E. coli K-12," said Riley. The scientists developed the best consensus on the status and properties of each of the E.coli K-12 genes at...

Not just the birds

...urn to the islands to nest. The region is its own experimental test site. The foxes were introduced to almost a quarter of the islands, about 100 total. The seabirds that inhabited the islands transported nutrients from the nearby seas to the islands via their guano, or excrements. Rich in phosphorous and ni...

Chemical signaling helps regulate sensory map formation in the brain

...als. In the process, they have provided the first experimental evidence for a decades-old model of how nerve cells establish distant connections in a way that can consistently relay spatial information. In the January 5, 2006, issue of the journal Nature, the researchers show that a gradient of a molecule known...

New Research Shows Artificial Light at Night Stimulates Breast Cancer Growth in Laboratory Mice

...tific journal Cancer Research. “This is the first experimental evidence that artificial light plays an integral role in the growth of human breast cancer,?said NIEHS Director David A. Schwartz, M.D. “This finding will enable scientists to develop new strategies for evaluating the effects of light and other envir...

Healing honey: The sweet evidence revealed

... as an additional 16 trials that were performed on experimental animals. Honey was found to be beneficial as a wound dressing in the following ways: Honey's antibacterial quality not only rapidly clears existing infection, it protects wounds from additional infection Honey debrides wounds and removes malodor Ho...

Is the brain wired for faces?

... researchers then tested these predictions against experimental data measured in a functional Magnetic Resonance Imaging (fMRI) machine, a high-powered imaging technology that can measure the brain activity of test subjects, and by other behavioral techniques. Subjects were shown pairs of images of similar human ...

Markers of gene, protein, or micro-RNA activity predict outcome in prostate and colorectal cancers

...all in the "gray zone" of traditional tests. This experimental "universal bead array" test, which is designed to be low cost and easy to administer, appears to be a better predictor of relapse and disease-free survival than the Gleason Score, according to lead author Jessica Wang-Rodriguez, M.D., associate clini...
