Lapatinib-pazopanib combination therapy not beneficial for patients with inflammatory breast cancer

Inflammatory breast cancer is a very aggressive type of cancer associated with early metastasis and poor survival rates, and the prognosis is even worse for patients with tumors expressing the ErbB2 receptor. The ErbB2-inhibiting drug lapatinib can slow the spread of cancer cells in individuals with advanced breast cancer who have already tried other chemotherapy medications.

Formation of blood vessels in tumors attacked from two angles

As soon as they have grown to pinhead size, tumors rely on the formation of new blood vessels - a process which is scientifically called angiogenesis. Interfering with this process (antiangiogenesis) is considered to be a promising approach in cancer medicine. However, those drugs that are already available for preventing the sprouting of new blood capillaries have failed to fulfill the high expectations placed on them.

LILRB2 receptor plays an important role in keeping stem cells from differentiating

An immune-system receptor plays an unexpected but crucially important role in keeping stem cells from differentiating and in helping blood cancer cells grow, researchers at UT Southwestern Medical Center report today in the journal Nature.

UCSB creates synthetic platelets for various biomedical applications

Synthetic platelets have been developed by UC Santa Barbara researchers, in collaboration with researchers at Scripps Research Institute and Sanford-Burnham Institute in La Jolla, Calif. Their findings are published in the journal Advanced Materials in a paper titled "Platelet Mimetic Particles for Targeting Thrombi in Flowing Blood."

ASCs promising source of cells for use in plastic surgery and regenerative medicine

Adipose stem cells (ASCs)—stem cells derived from fat—are a promising source of cells for use in plastic surgery and regenerative medicine, according to a special review in the June issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons.

Secreted vesicles play role in spread of cancer

Cancer researchers have known for well over a century that different tumor types spread only to specific, preferred organs. But no one has been able to determine the mechanisms of organ specific metastasis, the so-called "soil and seed" theory of 1889. New details that could help shed light on this hypothesis have been provided by a team of researchers from Weill Cornell Medical College, Memorial Sloan-Kettering Cancer Center, and their collaborators, proposing a new mechanism controlling cancer metastasis that offers fresh diagnostic and treatment potential.

Bioengineers develop first structure to grow small human blood vessels

Mice and monkeys don't develop diseases in the same way that humans do. Nevertheless, after medical researchers have studied human cells in a Petri dish, they have little choice but to move on to study mice and primates. University of Washington bioengineers have developed the first structure to grow small human blood vessels, creating a 3-D test bed that offers a better way to study disease, test drugs and perhaps someday grow human tissues for transplant.

AngioPredict project to focus on patients with metastatic colorectal cancer

The Royal College of Surgeons in Ireland (RCSI) is leading an international team of scientists on a major research study which aims to predict colorectal cancer patients' response to the 'angiogenesis inhibitor' class of anti-cancer drug which prevents growth of tumour blood vessels. The study will facilitate a more focused therapeutic approach thus limiting side-effects in patients.

Researchers to create new type of bioactive coating for brain aneurysm stents

Researchers at Purdue University are working with the U.S. Army and neurosurgeons at the Walter Reed National Military Medical Center to create a new type of "bioactive" coating for stents used to treat brain aneurysms including those caused by head trauma from bomb blasts.

Polarization Gating Spectroscopy may detect pancreatic cancer

By simply shining a tiny light within the small intestine, close to that organ's junction with the pancreas, physicians at Mayo Clinic's campus in Florida have been able to detect pancreatic cancer 100 percent of the time in a small study.

New knowledge related to host-parasite interaction in severe malaria

Researchers from Seattle Biomedical Research Institute, the University of Copenhagen and the University of Edinburgh have uncovered new knowledge related to host-parasite interaction in severe malaria, concerning how malaria parasites are able to bind to cells in the brain and cause cerebral malaria - the most lethal form of the disease.

Human cytomegalovirus associated with neovascular AMD

A team of researchers, including a scientist from the Viral Immunology Center at Georgia State University, have found that a type of herpesvirus infection of the eye is associated with neovascular age-related macular degeneration (AMD), a disease that causes blindness in the elderly.

New optical microscope sees individual blood cells as they flow inside the body

Blood tests convey vital medical information, but the sight of a needle often causes anxiety and results take time. A new device developed by a team of researchers in Israel, however, can reveal much the same information as traditional blood test in real-time, simply by shining a light through the skin.

Biomarker neutralizes effect of bevacizumab in pancreas and kidney cancer patients

Diether Lambrechts (VIB - KU Leuven) said "in two large clinical studies with patients with advanced stages of pancreas and kidney cancer a variant in the DNA was discovered that identified patients who did not respond well to the prescribed course of bevacizumab.

Specialized high volume centers linked with lower rates of death and disability from aSAH

People with bleeding brain aneurysms have the best chance of survival and full recovery if they receive aggressive emergency treatment from a specialized team at a hospital that treats a large number of patients like them every year, according to new guidelines just published by the American Stroke Association.
