  1. Although relocating can be stressful, a new study at the University of Missouri found Black South Africans who migrated far away from home to find work reported better emotional well-being and were at lower risk for depression after the move on average.
  2. For the first time, researchers have discovered that prostate cancer can be killed by targeting a single enzyme, called PI5P4Kα. The findings, published recently in Science Advances, could help address the growing threat of treatment resistance in prostate cancer and could also lead to improved treatments for other cancers, such as those affecting the breast, skin, and pancreas.
  3. A new research perspective was published in Genes & Cancer on January 30, 2023, entitled, "Leveraging a powerful allogeneic dendritic cell line towards neoantigen-based cancer vaccines."
  4. A race-based adjustment to test-result values from a common prenatal screening should be discontinued, according to a study published this week in Obstetrics and Gynecology. The adjustment has historically been applied only with Black women.
  5. The Strategic Memory Advanced Reasoning Tactics (SMART) brain health training protocol has been shown to improve symptoms of depression, anxiety and stress when delivered in person. New research from Center for BrainHealth at The University of Texas at Dallas demonstrates the effectiveness of online delivery of SMART.
  6. A recent study from UiB shows that elevated plasma methylmalonic acid predicts increased risk of acute myocardial infarction and mortality in patients with suspected or verified coronary heart disease.
  7. Twenty years ago, 4 out of 10 European children ate fruit and vegetables daily. Today, the proportion is the same, in spite of schemes to provide children with fruit at school. Why hasn't there been more improvement?
  8. A research team from LKS Faculty of Medicine, the University of Hong Kong (HKUMed) discovered that somatic deletion of a tumor suppressor gene AKTIP promotes luminal breast cancer development and resistance to endocrine therapy. The findings are now published in Cell Reports.
  9. Mnemo Therapeutics, a biotechnology company developing transformational immunotherapies, has announced publication of two scientific studies developed at Institut Curie, its closest academic collaborator, in the journal Science Immunology. The publications reveal TE-exon splicing junctions act as a source of novel recurrent, cancer-specific targets and have potential implications for developing more effective and less toxic immunotherapies. The findings presented further validate Mnemo's antigen discovery platform, which is a critical driver of the company's cell therapy pipeline.
  10. If you live near a busy road, it may increase your stress levels and affect your sleep. When we are under stress and sleep poorly, we may be at a higher risk of developing tinnitus.
  11. Early vascular damage and atherosclerosis in adolescents may be caused by low-grade inflammation, a paper published in the Journal of Applied Physiology concludes. The study was conducted in collaboration between the University of British Columbia in Canada, the University of Bristol in the U.K., the University of Exeter in the U.K., the University of Illinois in the U.S., and the University of Eastern Finland.
  12. There is currently no drug for treating non-alcoholic fatty liver disease, which affects many people with type 2 diabetes and which can result in other serious liver diseases. A study led by researchers from Karolinska Institutet has now identified a drug candidate for the treatment of fatty liver. The preclinical study, published in the Journal of Hepatology, indicates that an antibody that blocks the protein VEGF-B presents a possible therapeutic option for fatty liver disease.
  13. Fraunhofer researchers have succeeded in using the bioresorbable silica gel Renacer to produce an electrospun membrane that is neither cytotoxic to cells nor genotoxic. This model mimics fibrous structures found in connective tissue and is therefore particularly suitable for regenerative applications, such as for improved wound healing.
  14. U.S. agriculture officials on Friday proposed new nutrition standards for school meals, including the first limits on added sugars, with a focus on sweetened foods such as cereals, yogurt, flavored milk and breakfast pastries.
  15. Primary lung neuroendocrine tumors are very rare tumors that represent about 1-2% of all lung cancer cases. Only 2,000 to 4,500 are diagnosed in the U.S. each year. The common treatment for early stage lung neuroendocrine tumors is surgery, but that is not an option for all patients. Researchers at Moffitt Cancer Center are investigating new treatment approaches for this patient population.
  16. People who know someone who became ill with COVID-19 or died from the disease are twice as likely to receive a COVID-19 vaccine, according to a study led by Rutgers and Penn State University.
  17. They are barely the size of a thumbnail, able to communicate with each other and respond to each other, and designed to make life easier for people with functional limitations. We are talking about a new generation of interactive microimplants developed by the innovation cluster INTAKT, which is supported by the German Federal Ministry of Education and Research (BMBF) and coordinated by the Fraunhofer Institute for Biomedical Engineering IBMT. These miniature assistants can act as a stimulus in cases of tinnitus or digestive tract disorders or help a person's hand to regain the ability to grip.
  18. A new study published in the Journal of Clinical Endocrinology and Metabolism found that age-related accumulation of abdominal fat is associated with lower muscle density. Low muscle density means the muscle has more fat in it, which can lead to less effective muscle function that in turn may lead to more falls.
  19. Researchers at the University of Sussex are using Artificial Intelligence (AI) technology to analyze different types of cancer cells to understand different gene dependencies, and to identify genes that are critical to a cell's survival. Sussex researchers have done this by developing a prediction algorithm that works out which genes are essential in the cell, by analyzing the genetic changes in the tumor. This can be used to identify actionable targets that in time could guide oncologists to personalize cancer patient treatments.
  20. First Nations, Métis and Inuit people with primary biliary cholangitis—a debilitating autoimmune liver disease—have more advanced symptoms at diagnosis and worse long-term outcomes than others in Canada, according to research from a nationwide monitoring project.
