3D fruit fly images to benefit brain research

The fragile head and brain of a fly are not easy things to examine but MRC scientists have figured out how to make it a little simpler. And they hope their research will shed light on human disease.

Nanoparticle drug delivery shows promise for the future of brain tumour therapy

A nanoparticle drug delivery system designed for brain tumour therapy has shown promising tumour cell selectivity in a novel cell culture model devised by scientists at The University of Nottingham. The project, conducted jointly by the Schools of Pharmacy, Biomedical Sciences and Human Development, will be featured in the September issue of the Experimental Biology and Medicine.

Researchers chart the level of gene expression in melanoma cell lines

Other than visually inspecting the disease, doctors have no genetic blueprint to classify melanomas, a lethal form of skin cancer.

Scientists identifiy successfully reprogrammed cells by looks alone

Some scientific results are hard to spot, especially in genetic research. Often scientists are unable to physically see if the gene they inserted into a cell has produced the desired trait.

Cell-based sensor for analysis of EGFR biomarker expression in oral cancer

Using a microfluidic device designed to capture and enrich cells from biological samples, a research team at The University of Texas at Austin has developed a test that can detect an important early marker for oral squamous cell carcinoma, which accounts for more than 90 percent of oral cancers. Oral cancer is the sixth most common cancer worldwide and is difficult to detect early enough to treat successfully.

Clemson scientists improve longevity of fluorescent nanoparticles

Clemson University chemists have developed a method to dramatically improve the longevity of fluorescent nanoparticles that may someday help researchers track the motion of a single molecule as it travels through a living cell.

Direct pathways between extracellular material and cell nuclei discovered

A team of Brooklyn College researchers has shattered a long-held belief that no direct pathway exists between material outside of a cell and the cell nucleus.

First 3D images of a living cell

A new imaging technique developed at MIT has allowed scientists to create the first 3D images of a living cell, using a method similar to the X-ray CT scans doctors use to see inside the body.

New cancer stem cells could aid breast cancer research

In some ways, certain tumors resemble bee colonies, says pathologist Tan Ince. Each cancer cell in the tumor plays a specific role, and just a fraction of the cells serve as "queens," possessing the unique ability to maintain themselves in an unspecialized state and seed new tumors. These cells can also divide and produce the "worker" cells that form the bulk of the tumor.

New insights into cell division process

Which genes are passed on from mother to child is decided very early on during the maturation of the egg cell in the ovary.

TRF2 and POT1 proteins found on telomeres control DNA damage response pathways

No sooner had cells evolved linear chromosomes than they had a life-threatening problem to solve.

Promising new line in anti-cancer therapy

A promising new line in anti-cancer therapy by blocking the molecular motors involved in copying genetic information during cell division is being pursued by young Dutch researcher Dr. Nynke Dekker in one of this year's EURYI award winning projects sponsored by the European Science Foundation (ESF) and the European Heads of Research Councils (EuroHORCS).

Bacteria - you can live without 'em, but it won't do you any good!

The finding challenges the conventional wisdom that even harmless bacteria – and the immune response they provoke – suck up the energy of the host organism and hasten its death.

Scientists discover the dynamics of transcription in living mammalian cells

Transcription the transfer of DNA's genetic information through the synthesis of complementary molecules of messenger RNA forms the basis of all cellular activities.

Mechanistic model of DNA repair

Ionizing radiation, toxic chemicals, and other agents continually damage the body's DNA, threatening life and health: unrepaired DNA can lead to mutations, which in turn can lead to diseases like cancer.

New detection techniques for pancreatic cancer

Using novel light-scattering techniques, researchers have found the first evidence that early stage pancreatic cancer causes subtle changes in part of the small intestine.

Screening method for pancreatic cancer in asymptomatic patients

EVANSTON, Ill. --- Optical technology developed by a Northwestern University biomedical engineer shown to be effective in the early detection of colon cancer now appears promising for detecting pancreatic cancer, the fourth most common cause of cancer deaths in the United States.

Web site puts physicians and hospitals under microscope

As health consumers across the country demand better and more detailed information about their physicians and hospitals, Beth Israel Deaconess Medical Center (BIDMC) is stepping up to detail its own performance efforts ranging from the percentage of clinicians who clean their hands to the number of times physicians take the proper steps in treating heart attack patients.
