A new study from Lund University in Sweden raises questions about the efficacy of bariatric operations involving gastric bypass. The results show that the biggest metabolic changes happened directly after surgery. Just a year after the operation, the concentration of metabolites and fats had returned to almost the same levels as before the procedure. Previous research has shown that the majority o

As certain tumor cells are able to conceal themselves in the body, it often means that patients with aggressive cancers experience a recurrence of the cancer after treatment. By programming genetically modified killer immune cells to seek and destroy the hiding tumor cells and tumor stem cells, it is hoped that we can develop more effective treatment options. An international research project, wit

BRCA1 and BRCA2 are well-known breast cancer genes associated with a significantly increased risk of hereditary breast and ovarian cancer. However, there are an additional eleven genes associated with elevated risk for these types of cancer. A multi-year Swedish study now reveals that the proportion of women with genetically confirmed hereditary breast cancer doubled by including all genes in the

Is it possible that a single biomarker can detect all types of diseases related to dopamine deficiency in the brain? Yes, that's what a research group in Lund is discovering. "We have observed that an enzyme in cerebrospinal fluid and in blood is a useful marker for identifying all types of Parkinson's-related diseases with high accuracy," says Oskar Hansson, who led the study. The marker in quest

Currently, a lot is known about which genes are responsible for our individual blood groups, however not much is understood about how and why the levels of the blood group molecules differ between one person and another. And this can be important for blood transfusion safety. Now a research group in Lund has developed a toolbox that finds the answer – and in doing so, has solved a 50-year-old myst

An international consensus report on diabetes identifies the potential for diabetes screening, better classification of type 2 diabetes, and biomarkers that can predict cardiovascular disease. The report also highlights that more evidence is needed before it is possible to provide individualised treatment to all patients. The report is based on a large collaboration between 28 universities worldwi

A research group at Lund University has studied how a molecular sensor located in the blood vessel wall, controls how the vessel compensates for high blood pressure. As we age, the sensor deteriorates, which can worsen vascular damage caused by high blood pressure and consequently lead to secondary diseases affecting the heart, brain, or other organs. In mice, the researchers demonstrate that the

The rapidly rising levels of carbon dioxide in the atmosphere affect plants’ absorption of nitrogen, which is the nutrient that restricts crop growth in most terrestrial ecosystems. Researchers at the University of Gothenburg have now revealed that the concentration of nitrogen in plants’ tissue is lower in air with high levels of carbon dioxide, regardless of whether or not the plants’ growth is

The photosynthesis of tropical species in montane rain forest is very sensitive to high temperature which means high-altitude rain forests are particularly under threat by global warming. This has been shown by researchers from the University of Gothenburg in a study published in the journal New Phytologist. An increase in temperature usually stimulates photosynthesis and growth for plants at our

Solar storms and the particles they release result in spectacular phenomena such as auroras, but they can also pose a serious risk to our society. In extreme cases they have caused major power outages, and they could also lead to breakdowns of satellites and communication systems. According to a study published today in Nature Communications, solar storms could be much more powerful than previousl

Africa is very vulnerable to climate change. However, challenges remain in understanding the full set of climate impacts for the region. Improved climate models may help contribute to solutions for reducing vulnerability. A step in the right direction, according to the researchers Minchao Wu and Markku Rummukainen, is to incorporate into todays climate models how regional ecosystems are affected b

Most African countries contribute only marginally to the increase of greenhouse gases, such as carbon dioxide, in the atmosphere. Nevertheless, Africa is the continent most vulnerable to the effects of climate change. The impact varies across the continent and also within individual countries. An improved set of data increases the possibilities for evaluating future risks, and how to best address

New data presented by researchers at Lund University and others in the journal Oceanologia show that the air along the coasts is full of hazardous nanoparticles from sea traffic. Almost half of the measured particles stem from sea traffic emissions, while the rest is deemed to be mainly from cars but also biomass combustion, industries and natural particles from the sea. “This is the first time an
