Physiologists, neuropathologists identify origin of cancer metastasis formation

It is not primary tumors that are responsible for the majority of cancer deaths, but rather their metastases. Physiologists and neuropathologists from the University of Zurich have now identified the origin of metastasis formation, thereby becoming the first to reveal the pathway of metastasizing intestinal cancer cells out of the blood stream. The results allow new approaches in the development of cancer therapies.

Arrowhead initiates Adipotide Phase 1 trial in obesity

Arrowhead Research Corporation, a targeted therapeutics company, today announced that the first patient has been dosed in a Phase 1 clinical trial with Adipotide, a new class of treatment for obesity.

Neonate blood-brain barrier more intact than adults following stroke

The ability for substances to pass through the blood-brain barrier is increased after adult stroke, but not after neonatal stroke, according to a new study the UCSF that will be published July 11 in the Journal of Neuroscience.

Breast cancer drug bevacizumab slows progression but has no overall survival benefit

The cancer drug bevacizumab (Avastin®) offers only a modest benefit in prolonging disease progression in patients with advanced stage breast cancer, according to a systematic review by Cochrane researchers. The researchers assessed the efficacy of bevacizumab in combination with chemotherapy, an established cancer treatment in this indication, and found no overall survival benefit when adding bevacizumab to chemotherapy.

New method uses acoustic angiography to identify cancer in minutes

From the air, the twists and turns of rivers can easily be seen. In the body, however, tracing the twists and turns of blood vessels is difficult, but important. Vessel "bendiness" can indicate the presence and progression of cancer.

Shear forces cause vessel identity crisis

Lymphatic vessels exposed to fast-flowing blood take on characteristics associated with blood vessels, report researchers.

Scientists develop novel anticancer drug designed to travel through the bloodstream

Scientists at the Johns Hopkins Kimmel Cancer Center, working with Danish researchers, have developed a novel anticancer drug designed to travel -- undetected by normal cells -- through the bloodstream until activated by specific cancer proteins.

Gene defect linked to cluster of systemic complications

Research teams from The University of Texas Health Science Center at Houston (UTHealth) and Paris, France have discovered a gene defect linked to a cluster of systemic complications, including life-threatening thoracic aortic disease and intracranial aneurysms. The new syndrome is similar, but distinct from known syndromes such as Marfan and Loeys-Dietz syndrome.

Special surface coating for stents to keep them in place

If a person's windpipe is constricted, an operation in which the surgeon inserts a stent to enlarge the trachea is often the only way to relieve their respiratory distress. But this grid-like implant can slip out of position, closing off the windpipe altogether. Researchers are working on a special surface coating for the stents to keep them in place.

Mouse model demonstrates role of AEG-1 in hepatocellular carcinoma

Researchers have created the first mouse model demonstrating the role of a cancer promoting gene, Astrocyte elevated gene-1 (AEG-1), in hepatocellular carcinoma, or liver cancer. The mouse model represents a critical step in understanding the molecular mechanisms of liver cancer progression and could lead to novel therapies for the disease.

Novel biomimetic strategy can dissolve blood clots before they cause serious damage or even death

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a novel biomimetic strategy that delivers life-saving nanotherapeutics directly to obstructed blood vessels, dissolving blood clots before they cause serious damage or even death.

New class of injectable materials can stimulate tissue regeneration

The University of Nottingham has begun the search for a new class of injectable materials that will stimulate stem cells to regenerate damaged tissue in degenerative and age related disorders of the bone, muscle and heart.

FDC precursor cells exist in the wall of blood vessels

Chronic inflammatory conditions are extremely common diseases in humans and in the entire animal kingdom. Both in autoimmune diseases and pathogen-caused diseases, the inflamed areas are rapidly colonized by antibody producing B lymphocytes - which organize themselves in highly structured areas called "lymphoid follicles".

Scientists discover new signalling pathway that controls both obesity and atherosclerosis

A*STAR scientists from the Institute of Molecular and Cell Biology (IMCB) and the Singapore Bioimaging Consortium (SBIC) have discovered a new signalling pathway that controls both obesity and atherosclerosis.

Signs that a child is seriously ill: Interview with Professor Middleton

There are several signs that indicate that a child is seriously ill. These can be spotted by parents, teachers and carers as well as by me or any other doctor or nurse.

Treating Sickle Cell Disease with L-Glutamine

By focusing on how best to help patients, researchers can sometimes find solutions that are much simpler than anticipated. That has been the guiding approach to our efforts to develop a treatment for sickle cell disease.

Safety tips to prevent heatstroke during hot weather

People across the country are experiencing sweltering weather with temperatures and the heat index reaching well into the 100-degree range. While many will take refuge in air-conditioned homes or at a local lake or pool, it's important to remember that the heat can be much more than bothersome. It can put your health at risk and even prove life threatening.

Scientists discover Eya1 enzyme control of pulmonary barrier integrity

Scientists have provided the first evidence that an enzyme called Eya1 protein phosphatase is a critical regulator of lung function and that this may have broad implications for sufferers of a variety of pulmonary diseases.

3D printed templates of filament networks can improve function of engineered living tissues

Researchers are hopeful that new advances in tissue engineering and regenerative medicine could one day make a replacement liver from a patient's own cells, or animal muscle tissue that could be cut into steaks without ever being inside a cow.
