Nanoparticles to target the walls of blood vessels

Eric Shaqfeh studies blood at Stanford University, using computer models that simulate how the fluid and the cells it contains move around. One shows how components in blood line up to prepare for healing; the other demonstrates the best shape to use for man-made nanoparticles that target cancers - a surfboard.

Flu Pandemics

Current research suggests that the flu may predispose to secondary bacterial infections, which account for a significant proportion of mortality during flu pandemics. Influenza affects between 3 and 5 million people annually, causing up to 500,000 deaths worldwide.

Coronary Vessels

The cellulose produced by bacteria could be used for artificial blood vessels in the future as it carries a lower risk of blood clots than the synthetic materials currently used for bypass operations, reveals a thesis from the Sahlgrenska Academy at the University of Gothenburg, Sweden.

Serious Infectious Diseases

Diseases are common to every living being. We all get ill and suffer from several health problems throughout our life. But when these conditions occur in childhood extra care is required. In this article you will find some common childhood illnesses and disorders like chest infections, cough, asthma and influenza.

Xenical drug is prescribed for overweight individuals

Xenical drug is prescribed for overweight individuals and for overweight people who have other health problems like high blood pressure, diabetes, or high cholesterol levels. Your weight standing is set by your body mass index ( BMI ), a comparing of height to weight. Orlistat is available with a prescription under the name Xenical, and in a reduced strength as an over the counter brand called Alli...

Advanced prostate cancer

Patients with advanced prostate cancer are often treated with hormones, but when thetumoursstart growing again they have more and different blood vessels, reveals a thesis from the Sahlgrenska Academy, at the University of Gothenburg, Sweden. This discovery paves the way for new treatments for hormone-resistant prostate cancer. Late in the course of the disease, when the prostate cancer has spread, most patients are given hormone therapy. This reduces the production of the male sex hormone and the tumour shrinks.

Tumours have to make new blood vessels if they are to grow and spread in the body. The thesis shows that thetumoursthat have relapsed after a patient has been givenhormone therapycontain more blood vessels. The blood vessels often also look different to how they looked during the earlier stages of the disease. Online Pharmacy provides the access to health information and prescription medications.

Another interesting finding is that levels of a protein known as ADAMTS1 are lower in these aggressive tumours. This protein is known to inhibit the growth of blood vessels. Low levels of the protein in thetumoursare associated with more blood vessels and a greater spread of the cancer.

"If we can prevent the tumour from making new blood vessels, we can also prevent the cancer from spreading," says Gustavsson. "Now that we have a better understanding of how the formation of blood vessels is controlled in this stage of prostate cancer, we are in a better position to develop medicines that suppress the formation of new vessels in hormone-resistant prostate cancer."

The research team at the Sahlgrenska Academy will now assess how these changes affect the function of the blood vessels and their sensitivity to different treatments.
