Aptamer-targeted nanoparticles collect and detect cancer cells

Using magnetic and fluorescent nanoparticles capable of binding tightly to molecules found only on the surface of cancer cells, a team of investigators at the University of Florida has developed a method for collecting and detecting multiple cancer cells from biological samples.

Nanosized bioceramic particles could function as efficient gene delivery vehicles with target specificity for the spleen

A detailed comparison of different types of ceramic nanoparticles has found that those made of silica can efficiently transport therapeutic genes to the spleen and trigger a potent immune response capable of attacking tumors.

Quantum dots outline brain tumors for surgical removal

Although surgical removal of a tumor can be the most effective way of treating brain cancer, neurosurgeons are often faced with the dilemma of determining the exact border between a tumor and the healthy tissue that surrounds it.

Nanoparticle-enabled peptide delivery triggers tumor regression

Cells possess a variety of ways of dealing with mutations that can cause them to grow uncontrollably and eventually form a tumor. The tumor suppressor gene p53 plays a critical role in these cancer prevention processes, largely by triggering a form a cell death known as apoptosis.

Nanoprobes with near-infrared persistent luminescence for in vivo imaging

In a new take on use of luminescent nanoparticles as cancer imaging probes, a team of investigators from several research institutes in Paris, France, has developed new metal-containing nanoparticles that emit light for several hours after they are initially excited.

Interfacing silicon nanowires with mammalian cells

A research team at the University of California, Berkeley, has achieved a significant step toward one of the futuristic goals of nanomedicine and nanobiology-developing technology for "wiring" together individual cells.

Trial shows nanoparticle-enabled thermal therapy safe for treating cancer

Several types of metal nanoparticles are capable of converting energy, such as that carried by near-infrared light or an oscillating magnetic field, into heat at a level high enough to kill tumors.

Hybrid gold-dendrimer nanoparticles target and image tumors

Dendrimer nanoparticles, made of spherical, highly branched polymers, have shown promise as drug delivery vehicles capable of targeting tumors with large doses of anticancer drugs.

Double-duty nanoparticles overcome drug resistance in tumors

Cancer cells, like bacteria, can develop resistance to drug therapy. In fact, research suggests strongly that multidrug resistant cancer cells that remain alive after chemotherapy are responsible for the reappearance of tumors and the poor prognosis for patients whose cancer recurs.

Researchers create first 3-D optical images of human breast cancer in patients based on tissue fluorescence

Fluorescence diffuse optical tomography, or FDOT, relies on the presence of fluorophore molecules in tissue that re-radiate fluorescent light after illumination by excitation light of a different color.

Scientists observe cell migration

Johns Hopkins researchers have found a way to directly observe cell migration -- in real time and in living tissue. In a report in Developmental Cell, the scientists say their advance could lead to strategies for controlling both normal growth and the spread of cancer, processes that depend on the programmed, organized movement of cells across space.

Diets rich in fruits and vegetables best for breast cancer survival

A new study in the "Journal of Clinical Oncology" reinforces existing evidence showing that women with breast cancer can greatly reduce their risk of recurrence by eating a healthy plant-based diet rich in fruits and vegetables and making other healthy lifestyle choices, according to nutrition experts with The Cancer Project.

Malaria and Epstein-Barr virus in Africa

Endemic Burkitt lymphoma is a form of cancer that accounts for up to 74% of malignant disorders in children in equatorial Africa.

Priority review granted for oral formulation of HYCAMTIN (topotecan)

GlaxoSmithKline (GSK) has announced that its new drug application (NDA) for ORAL HYCAMTIN (topotecan) capsules, a treatment for relapsed small cell lung cancer (SCLC), has been granted Priority Review by the United States Food and Drug Administration (FDA).

Eurand files NDA for Zentase for the treatment of exocrine pancreatic insufficiency

Eurand has announced that Eurand Pharmaceuticals Ltd. initiated the rolling submission of its new drug application (NDA) with the U.S. Food and Drug Administration (FDA) for Zentase for the treatment of Exocrine Pancreatic Insufficiency (EPI). Zentase (formerly EUR-1008), the company's lead product candidate, has been granted fast-track designation by the FDA.

Impact of diet or physical activity on breast cancer survival

Breast cancer survivors who eat a healthy diet and exercise moderately can reduce their risk of dying from breast cancer by half, regardless of their weight, suggests a new longitudinal study from the Moores Cancer Center at the University of California, San Diego (UCSD).

A single cancer stem cell is sufficient to initiate and maintain a malignant tumor

At the heart of most, if not all cancers, lie a handful of wayward stem cells that feed the ever growing tumor mass, but their scarcity make it difficult for scientists to study them. Now, times of plenty may lie ahead as a breast cancer cell line , established long ago , turned out to behave a lot like cancer stem cells.

Cancer death rates remain high decades after exposure to arsenic

Death rates from lung and bladder cancer remained high decades after residents in northern Chile were exposed to high levels of arsenic in their drinking water, according to a new study by researchers from the University of California, Berkeley, and the Pontificia Universidad Cat'lica de Chile in Santiago.

BRCA2 carriers more likely to develop aggressive and lethal prostate cancer

Carriers of a BRCA2 variation specific to Iceland are more likely to develop aggressive and lethal prostate cancer than noncarriers, according to a study published online in the Journal of the National Cancer Institute.

Study compares cord blood to bone marrow for transplants

Umbilical cord blood transplants may offer blood cancer patients better outcomes than bone marrow transplants, according to an analysis of outcome data performed at the Statistical Center, Center for Blood and Marrow Transplant Research (CIBMTR), Medical College of Wisconsin, Milwaukee.
