Beauty is number one

21 April, 2005 - Linköpings universitet

A beautiful exterior bolsters your self-esteem and thereby helps keep you healthy. This is a common argument in favor of beauty surgery, which has been scrutinized in a dissertation from Linköping University in Sweden. Beauty surgery, or aesthetic surgery, is a rapidly growing business. The first clinic in Sweden opened in the 1980s. Today there are more than 30 clinics that offer aesthetic surgery.

Short sugar chains – a future drug for Alzheimer’s?

19 April, 2005 - Uppsala universitet

Heparansulfate, which is needed for normal fetal development among other things, is also important for the build-up of amyloid, morbid protein deposits that appear in several serious diseases. This is shown by Uppsala scientists in an article published in today’s Net edition of the U.S. journal Proceedings of the National Academy of Science.

Drugs targeted at muscle cells can be of use in the treatment of diabetes patients with insulin resistance

18 April, 2005 - Karolinska Institutet

Type 2 diabetes is a clinical disease characterised by disruption to the metabolism of glucose and lipids as well as to the production of and physiological reactions to insulin. These disruptions are partly due to a reduced absorption of glucose in the cells that form the body’s fat and muscle tissue. Now scientists at Karolinska Institutet have established that a type of drug targeted at receptors in the muscle cells increases the metabolism and absorption of glucose, making it a potential tool in the treatment of diabetes.

Umeå researchers have mapped the dams of the world

15 April, 2005 - Umeå universitet

More than half of the world’s large rivers are fragmented and regulated by dams. The largest and the most biologically and geographically diverse rivers are all affected. This is shown by a global study that is published in this week’s issue of the journal Science.

Signatures of the first stars

15 April, 2005 - Uppsala universitet

A primitive star with extremely low iron content has been discovered by an international research team from Sweden, Japan, Germany, USA, Australia and Great Britain. This indicates the original composition of the gas from which the star formed had low iron content. The results are published in Nature online this week.

New treatment for hereditary breast cancer

14 April, 2005 - Stockholms universitet

Researchers at Stockholm University have, together with colleagues in England, discovered a new way of treating and preventing hereditary breast cancer. The article, published in Nature, describes how the use of a chemical inhibitor can specifically kill tumour cells, which have a defect in the gene causing hereditary breast cancer. This new treatment targets only the tumour cells and is not likely to affect other healthy cells in the body. The discovery could also lead to a prophylactic treatment for hereditary breast cancer.

Lund University part of EU project on global land destruction

14 April, 2005 - Lunds universitet

The EU is now entering an agreement with Lund University regarding research into the desertification. The background is that 40 research organizations from 16 countries recently gathered in Madrid to launch an EU project (DeSurvey) about land degradation and desertification in Europe, Africa, Asia, and South America. The EU funding is about SEK 75 million. Lund University will be taking part as the only Scandinavian unit, in the person of Professor Ulf Helldén at the Department of Physical Geography and Ecosystem Analysis and the Center for GeoBiosphere Science.

Domain protecting proteins from degradation identified

14 April, 2005 - Karolinska Institutet

The first stabilizing signal that protects a protein from degradation has been identified. This finding from researchers at Karolinska Institutet, Sweden, is presented in the journal Molecular Cell, April 15, 2005.
