Research reveals that diarrheal bacteria can cause colon cancers

Johns Hopkins scientists say they have figured out how bacteria that cause diarrhea may also be the culprit in some colon cancers. The investigators say that strains of the common Bacteroides fragilis (ETBF) dupe immune system cells into permitting runaway colon tissue inflammation, a precursor for malignant growth.

New technique may help clinicians in diagnosing pleural effusion

A new technique may help clinicians hone in on a diagnosis in patients presenting with a pleural effusion of unknown cause.

Tiny filaments extending from cells may play a role in common malignant brain tumors

UCSF scientists have discovered that a tiny filament extending from cells, until recently regarded as a remnant of evolution, may play a role in the most common malignant brain tumor in children.

New minimally invasive surgery techniques and instruments reduce tissue damage and infection

New, delicate surgery techniques to hunt for tumours could benefit from a lighter touch - but from a robot, rather than from a human hand. Canadian researchers have created a touchy-feely robot that detects tougher tumour tissue in half the time, and with 40% more accuracy than a human. The technique also minimises tissue damage.

Genway Clinical Laboratory offers ELISA-based test that detects tumor markers in blood serum

GenWay Clinical Laboratory, a US-based diagnostic company with CLIA certification, has validated a general tumor marker test in their laboratory and now offers this testing service. This is an ELISA-based assay which simply requires a small blood sample from the patient in order to quantify the amount of the tumor marker in their serum.

Scientists develop new technique to target brain cancer cells

Scientists from the U.S. Department of Energy's (DOE) Argonne National Laboratory and the University of Chicago's Brain Tumor Center have developed a way to target brain cancer cells using inorganic titanium dioxide nanoparticles bonded to soft biological material.

CEL-SCI expands work on current H1N1 virus vaccine

CEL-SCI Corporation has announced that it is expanding the scope of its work towards creating a novel treatment and vaccination against the current H1N1 virus, as well as a future mutated form in which the virus has acquired greater morbidity and mortality.

Gloucester Pharma announces FDA Advisory Committee Meeting to discuss Romidepsin NDA

Gloucester Pharmaceuticals will discuss the New Drug Application for romidepsin to treat patients with cutaneous T-cell lymphoma (CTCL) at the Oncologic Drugs Advisory Committee (ODAC) meeting on September 2, 2009.

New tumour theory could change cancer treatment

University of Sydney researcher Dr Guy Lyons has come up with a new theory of cancer tumours that could change the way we treat cancer and conduct research into its causes.

Medical imaging: The good, the bad and the ugly

In the political minefield of healthcare reform, medical imaging has emerged as a microcosm of this contentious debate. Congress has been charged with a high stakes, high wire balancing act: to create a bill preserving quality and access while trimming unethical and unnecessary spending. Medical imaging represents such a challenge, with its undeniable benefits tainted by inappropriate use.

Living cells controlled with light; potential for stem cell research

University of Central Florida researchers have shown for the first time that light energy can gently guide and change the orientation of living cells within lab cultures. That ability to optically steer cells could be a major step in harnessing the healing power of stem cells and guiding them to areas of the body that need help.

Oxygen nanosensor could improve tumor imaging

A new material developed at the University of Virginia - an oxygen nanosensor that couples a light-emitting dye with a biopolymer - simplifies the imaging of oxygen-deficient regions of tumors. Such tumors are associated with increased cancer aggressiveness and are particularly difficult to treat.

STAT3 is required for proliferation and maintenance of multipotency in glioblastoma stem cells

In a study published online in advance of print in Stem Cells, Tufts researchers report that the STAT3 gene regulates cancer stem cells in brain cancer. Cancer stem cells have many characteristics of stem cells and are thought to be the cells that drive tumor formation. The researchers report that STAT3 could become a target for cancer therapy, specifically in Glioblastoma multiforme (GBM), a type of malignant and aggressive brain tumor.

Discovery of a potential target for metastatic cancer

The deadliest part of the cancer process, metastasis, appears to rely on help from macrophages, potent immune system cells that usually defend vigorously against disease, researchers at Albert Einstein College of Medicine of Yeshiva University report.

Breastfeeding appears to reduce risk of breast cancer among women with family history

Women with a family history of breast cancer appear to have a lower risk of developing the disease before menopause if they have ever breastfed a child, according to a report in the August 10/24 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

Immune system protects cancer cells in first few days

During the very first few days of development of a cancer, our immune system recognizes cancer cells not as abnormal cells requiring eradication but as cells of the body that need to be protected. This result was obtained by the team led by David Klatzmann at the Laboratoire Immunologie (UPMC / CNRS / INSERM).

Epigenetic alterations may serve as markers for chronic leukemia

A new study shows that certain genes are turned off early, before clinical signs of the disease appear, in the development of chronic leukemia.

Discovery of potential candidate protein for cancer vaccines

Researchers at the University of Pittsburgh School of Medicine have learned that some healthy people naturally developed an immune response against a protein that is made in excess levels in many cancers, including breast, lung, and head and neck cancers. The finding suggests that a vaccine against the protein might prevent malignancies in high-risk individuals.
