The research, which involved 535,000 patients, reveals that 31 out of 33 autoimmune diseases studied were associated with an increased risk of pulmonary embolism.
A study from Lund University has discovered a molecular link between type 2 diabetes and cancer, highlighting the role of the TCF7L2-p53-p53INP1 pathway in protecting pancreatic beta cells. The risk variant of TCF gene is common and linked to both diabetes and certain types of cancer.
Svante Björck's study reveals that global warming events have not occurred simultaneously in the two hemispheres for 20,000 years. Instead, temperature changes are regionally specific, with similar effects only occurring during external processes like meteorite crashes or volcanic eruptions.
Researchers at Lund University have created a molecular image of a drug in human tissue using a special type of mass spectrometry. The technique allows for precise spatial distribution analysis, enabling the development of safer and more effective drug candidates.
A study from Lund University in Uganda found that almost one third of students have experienced sexual coercion, which is linked to risky sexual behavior. The researchers suggest targeting both perpetrators and victims to combat HIV in the country.
Researchers from Lund University have developed a method using ultrasound to improve the quality of transplanted blood stem cells. This improvement could lead to better treatment outcomes and reduced risk of graft-versus-host disease and infections.
A Swedish study published in American Heart Journal found that genetic factors are the primary cause of coronary heart disease, rather than family lifestyle. Adopted individuals with at least one biological parent having coronary heart disease had a 40-60% higher risk of developing the condition.
Researchers at Lund University have discovered a new function for vitamin C, finding that it can dissolve toxic protein aggregates in the brain that build up in people with Alzheimer's disease. The treatment has potential to delay and alleviate the progression of the disease by addressing its symptoms.
Researchers at Lund University have developed a new treatment option for advanced prostate cancer by targeting cancer stem cells with a STAT3-inhibitor. The study found that galiellalactone, a natural compound, has inhibitory effects on the growth of prostate cancer cells and prevents tumour growth and spreading.
A new measurement called 'glycemic profile' (GP) was developed to complement the existing glycemic index (GI) method. GP takes into account the shape and duration of the blood sugar curve after consuming a meal, providing a more accurate picture of the glucose response.
The DIAPREV-IT study, a three-year project funded by the Juvenile Diabetes Research Foundation, aims to vaccinate healthy children at high risk of developing type 1 diabetes. The researchers believe that vaccinating earlier in the disease process can save more beta cells and increase the vaccine's effectiveness.
A new genetic technique reprograms mature skin cells directly into brain cells without passing through the stem cell stage, opening a field for cell transplants. The discovery represents a fundamental change in the view of mature cell function, offering potential to treat neurodegenerative diseases like Parkinson's.
Researchers have discovered that dolphins can generate two sound beam projections simultaneously, each with different frequencies and directions. This ability could help dolphins locate objects more accurately, according to Dr. Josefin Starkhammar, who led the study published in Biology Letters.
Researchers mapped hereditary factors for venous thromboembolism in the Swedish population, finding higher risks in children of parents with VTE. Hereditary factors are significant at younger ages and occur equally in men and women, making a parental history an important risk factor to include in medical histories.
A study by Caroline Karlsson found that rats fed a specific lactic acid bacteria HEAL19 had significantly less weight and inflammation compared to those without the bacteria. Additionally, babies born vaginally have lactobacilli in their gut flora as early as two days after birth.
Two wine yeasts, S. cerevisiae and Dekkera bruxellensis, have been studied to reconstruct the evolutionary history of ethanol production. They developed similar abilities around 100-150 million years ago, likely driven by environmental pressures such as competition from other microbes.
A new blood-based test has the potential to diagnose Systemic Lupus Erythematosus (SLE) more quickly and accurately, allowing doctors to prescribe the right medication and prevent flares. The test uses a small chip to detect biomarkers in the body, creating a unique 'fingerprint' for each patient.
New research report shows dramatic changes in Arctic climate, including thawing permafrost and reduced snow cover. The carbon stored in permafrost is estimated to be double the amount of carbon dioxide in the atmosphere today.
Researchers use synchrotron radiation to detect amino acids in ancient bone tissue, confirming the presence of primary biomolecules. The study expands our understanding of protein preservation in fossils, challenging previous assumptions about the limited availability of soft tissues and endogenous biomolecules.
Researchers at Lund University have discovered a causal relationship between mutated Huntington's protein and weight gain in mice. The study shows significant changes in the brain's hormone control centre, leading to insulin resistance and metabolic dysfunction.

Researchers from Lund University and Mid Sweden University have identified a type of smell produced by bed bugs, known as alarm pheromones, which is repulsive to nymphs and potentially useful for controlling the pests. The study's findings suggest that the smells given off by adult and nymph bed bugs are surprisingly similar.
Researchers at Lund University found that terms describing male and female traits in animal sexual conflicts vary, with males often described in active terms and females in passive ones. This bias can lead to incorrect interpretations of results.
