Botox is a muscle-relaxing toxin used cosmetically and for other purposes Researchers mined a US database of side-effects experienced from medications Patients given Botox were compared with those using alternative treatments The team found that the former were 40–88% less likely to report depression Further tests will be needed to confirm if and how Botox...
by Macquarie University Researchers from Macquarie University have discovered a world-first new treatment that reverses the effects of memory loss associated with Alzheimer’s disease in a study of mice with advanced dementia. The research, co-led by two brothers, Dr. Arne Ittner and Professor Lars Ittner, from Macquarie University Dementia Research Center, builds on their work...
by Wellcome Trust Sanger Institute A study has revealed that tumors can evade the immune system by telling immune cells to produce immunosuppressive steroids. Researchers from the Wellcome Sanger Institute, Department of Pathology, University of Cambridge, and MRC Cancer Unit, discovered that immune T cells from mouse skin and breast tumors secrete steroids, and that...
MEMORIAL SLOAN KETTERING CANCER CENTER Cancer’s knack for developing resistance to chemotherapy has long been a major obstacle to achieving lasting remissions or cures. While tumors may shrink soon after chemotherapy, many times they eventually grow back. Scientists once thought that unique genetic mutations in tumors underlay this drug resistance. But more and more, they...
by Ludwig Maximilian University of Munich The immune system: Knocked off balanceInstead of protecting us, the immune system can sometimes go awry, as in the case of autoimmune diseases and allergies. An LMU team has dissected how mast cells regulate their calcium levels to keep the immune response under control. Credit: IMCES UK Essen/LMU Instead...

A novel lab-on-a-chip device reveals the blood type within minutes, holding much potential for use in an emergency TOKYO UNIVERSITY OF SCIENCE Blood transfusion, if performed promptly, is a potentially life-saving intervention for someone losing a lot of blood. However, blood comes in several types, some of which are incompatible with others. Transfusing an incompatible...
Adults with obesity are more susceptible to influenza A/H1N1pdm—the swine flu virus, according to a new study that did not, however, find a similar association with the seasonal flu. The results could be relevant in understanding the mechanisms by which infectious diseases such as influenza or the ongoing coronavirus pandemic might affect different segments of...

UW microbiologists discovered a bacterial toxin that, when engineered, is a key part of a gene editor that can make single-base changes in human mitochondria. The genome in mitochondria — the cell’s energy-producing organelles — is involved in disease and key biological functions, and the ability to precisely alter this DNA would allow scientists to...
