Researchers at EMBL Hamburg, in collaboration with scientists at the Leibniz Institute for Molecular Pharmacology (FMP), have created an unusually detailed map showing how influenza A reshapes infected human cells. Their customized workflow allowed them to directly observe protein interactions within intact cells, rather than relying solely on disaggregated samples. Seasonal influenza causes 3 million to 5 million severe cases and 650,000 deaths worldwide each year. Influenza A has also caused multiple pandemics, including the 1918 Spanish flu pandemic. After a virus enters a cell, it releases RNA that contains instructions for making a small set of viral proteins. These…

A naturally occurring compound called spermidine may help boost vaccine responses in some older adults by reducing the biological signs of aging in the immune system, according to research published in 2016. aged cells. As we age, our immune systems become less efficient, making it harder for our bodies to fight infections and respond fully to vaccines. This gradual decline, known as immunosenescence, increases vulnerability to age-related health problems and may leave some older people less protected after vaccination. Spermidine may support aging immunity The research was led by Dr Katya Simon, Group Leader in the Immune Cell Biology Laboratory…

Pygmy sperm whale (Kogia breviceps) are some of the least understood mammals in the ocean. They spend most of their lives far from the coast, usually traveling in small groups and diving deep to hunt squid and fish. Scientists have had little opportunity to observe them in the wild, as they are quiet and secretive, rarely appearing on land. Much of what researchers know about pygmy sperm whales comes from animals that wash ashore. Strandings are especially common along the southeastern United States, where this species occurs more frequently than almost any other large marine mammal. Whale stranding reveals hidden…

The increasing incidence of anemia and overweight, especially among children and adolescents, is recognized as a serious public health problem worldwide. Although the impact of anemia and obesity on an individual’s health is well documented, the underlying metabolic dysregulation, particularly regarding trace element homeostasis, is not fully understood, especially during critical early or subclinical stages. Traditional diagnostic markers often lack the sensitivity to detect these subtle changes.According to a study published in the KeAi journal Environmental chemistry and ecotoxicologyA group of Chinese researchers has pioneered an approach that integrates the analysis of 13 essential and non-essential trace elements with a…

Do you know your blood type? Blood type is important information used in blood transfusions, but few people realize that blood type can also be associated with disease risk. In the general population, people with blood type O have been reported to have a lower risk of cardiovascular disease and lower mortality from cardiovascular disease. Non-cardiovascular diseases are also associated with ABO blood types, such as certain cancers and infections. However, these numbers do not take into account the hemodialysis patient population, which faces higher risks than the general population. Cardiovascular disease is the leading cause of death in dialysis…

Researchers from Umeå University and partner institutions have developed an experimental anti-cancer drug that may be able to slow tumor growth and prevent the spread of aggressive prostate cancer. Their findings were published in the scientific journal Signal Transduction and Targeted Therapy. “This new drug was developed to prevent metastasis, and we are very happy and proud to have identified the mechanisms that promote cancer cell proliferation, invasion and metastatic spread,” said Marlene Lundström, professor of pathology at Umeå University’s Faculty of Medical and Biosciences, who led the study. Targeting advanced prostate cancer Prostate cancer is one of the most…

A small Italian study tested whether an individual’s preferred daily schedule matched up with hidden liver changes, but found no clear signs. Chronotype and Fibroscan-derived liver markers in obese adults: preliminary evidence from a cross-sectional study. Image credit: mybox / Shutterstock Recent research published in journals nutrients investigated the association between chronotype and FibroScan-derived fatty liver and fibrosis in overweight or obese adults. Circadian rhythms, chronotypes, and metabolic liver disease The circadian timing system synchronizes physiological and behavioral rhythms with external light-dark cycles to maintain metabolic balance. This system regulates energy metabolism, endocrine function, nutrition and sleep-related behaviors. Chronotype represents…

Researchers at the University of Minnesota Medical School have identified why the immune system has difficulty recognizing and attacking pancreatic cancer, paving the way for new approaches to improve immunotherapy. The survey results are Science Immunology.The study found that some cancer cells learn to hide from the immune system by shutting down processes that normally allow immune cells to detect them. Once hidden, these cancer cells are more likely to spread to other parts of the body.Researchers also discovered that certain immune cells known as regulatory T cells prevent other beneficial T cells from eliminating these hidden cancer cells. By…

In a phase 2 trial in patients with gastrointestinal cancers, 70% of patients receiving chemotherapy were able to stick to their treatment schedule with Avatrombopag, compared with 17% of patients receiving a placebo. Researchers at Massachusetts General Brigham Cancer Institute have found that the oral drug avatrombopag is safe and effective in managing persistent chemotherapy-induced thrombocytopenia (CIT) in more than half of patients with gastrointestinal cancers in a phase 2 clinical trial, providing a potential new option for managing a common and difficult complication associated with cancer treatment. Their works are Journal of Clinical Oncology. CIT occurs when chemotherapy lowers…

Weill Cornell Medicine researchers have developed a new AI-based method to evaluate patients with a blood cancer called myelodysplastic tumor. The method, published June 30 in the journal Leukemia, compares the physical location and morphometric (size and shape) characteristics of all hematopoietic cells in a patient’s bone marrow sample to those in healthy bone marrow, producing a score that reflects the severity of the disease. Myelodysplastic tumors (MDS) are a type of blood cancer that usually affects older people. About one-third of patients progress to a more aggressive form of cancer called acute myeloid leukemia. MDS patients must undergo frequent…
