New knowledge of basic science may be applied in future medical treatments

How does the developing pancreas in an embryo 'know' which cells are to produce insulin and which cells are to have other assignments? Researchers need to understand this if they want to be able to treat type-1 diabetes with stem cells developed into insulin-producing beta cells. At Lund University scientists have uncovered pioneering new knowledge, and are publishing it in the journal Cell.

Catheter-directed therapy: First-line treatment option for massive pulmonary embolism

Catheter-directed therapy or catheter-directed thrombolysis-an interventional radiology treatment that uses targeted image-guided drug delivery with specially designed catheters to dissolve dangerous blood clots in the lungs-saves lives and should be considered a first-line treatment option for massive pulmonary embolism, note researchers in the November Journal of Vascular and Interventional Radiology.

Researchers identify a new mechanism that inhibits the formation of new blood vessels

Researchers at Uppsala University, in collaboration with colleagues in Sweden and abroad, have identified an entirely new mechanism by which a specific protein in the body inhibits formation of new blood vessels. Inhibiting the formation of new blood vessels is an important aspect of, for example, cancer treatment. The study is published in the November issue of the journal Molecular Cancer Research.

Tips for treating age-related dermatologic concerns

Everyone expects their bodies to change as they get older. From wrinkles and sagging skin to brittle bones and aches and pains, the aging process is inevitable. In addition, there are a number of medical dermatologic conditions that surface with age that can cause people even more stress. Fortunately, dermatologists can help diagnose and treat these conditions no matter when they strike.

Peregrine Pharmaceuticals' bavituximab PS-targeting antibody demonstrates potent anti-tumor activity

Peregrine Pharmaceuticals, Inc. today announced that a newly published study shows that a phosphatidylserine (PS)-targeting antibody similar to the company's lead product candidate bavituximab demonstrated potent anti-tumor activity when combined with radiation in a model of aggressive brain cancer, doubling the survival time of test animals and producing long-term cures.

Potential new drug for lung cancer eliminates tumors in mice

A potential new drug for lung cancer has eliminated tumours in 50% of mice in a new study published today in the journal Cancer Research. In the animals, the drug also stopped lung cancer tumours from growing and becoming resistant to treatment. The authors of the research, from Imperial College London, are now planning to take the drug into clinical trials, to establish whether it could offer hope to patients with an inoperable form of lung cancer.

Gastroschisis may be associated with infections during pregnancy

Results of an investigation conducted by University of Nevada, Reno researchers, public health officials and area physicians published this week in the Archives of Pediatrics & Adolescent Medicine, indicate that Washoe County experienced a cluster of a particular birth defect, gastroschisis, during the period April 2007 - April 2008.

Gonorrhea medication may help fight cancer

Drugs sometimes have beneficial side effects. A glaucoma treatment causes luscious eyelashes. A blood pressure drug also aids those with a rare genetic disease. The newest surprise discovered by researchers at the Johns Hopkins University School of Medicine is a gonorrhea medication that might help battle cancer.

Women with high levels of homocysteine more likely to suffer from Alzheimer's disease

Middle-aged women with high levels of a specific amino acid in their blood are twice as likely to suffer from Alzheimer's many years later, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden. This discovery this could lead to a new and simple way of determining who is at risk long before there are any signs of the illness.

Scientists identify new behavioral traits of immune cells; findings may help in understanding complex diseases

In diseases such as multiple sclerosis, cells of the immune system infiltrate the brain tissue, where they cause immense damage. For many years, it was an enigma as to how these cells can escape from the bloodstream. This is no trivial feat, given that specialized blood vessels act as a barrier between the nervous system and the bloodstream.

Nanoparticles may cause DNA damage across a cellular barrier

Scientists have shown in the laboratory that metal nanoparticles damaged the DNA in cells on the other side of a cellular barrier. The nanoparticles did not cause the damage by passing through the barrier, but generated signalling molecules within the barrier cells that were then transmitted to cause damage in cells the other side of the barrier.

PAH patients face life-threatening risks from medication errors

Pulmonary arterial hypertension (PAH) patients using infused drugs have suffered serious injury or in some cases died from medication errors in hospitals and other inpatient settings, according to a peer-reviewed study by Accredo Health Group and several university hospitals that surveyed doctors, nurses and pharmacists.

Reduced VEGF can lead to degeneration of retina

Scientists at Schepens Eye Research Institute have found that when the eye is missing a diffusible form of vascular endothelial growth factor (VEGF), i.e. one that when secreted can reach other cells at a distance, the retina shows defects similar to "dry" macular degeneration, also called geographic atrophy (GA).
