In a study that followed more than 2,000 community-dwelling older adults over eight years, researchers say they have significant new evidence of a link between decreased sense of smell and risk of developing late-life depression. “We’ve seen repeatedly that a poor sense of smell can be an early warning sign of neurodegenerative diseases such as […]
Researchers at Karolinska Institutet in Sweden have identified a group of nerve cells in the mouse brain that are involved in creating negative emotional states and chronic stress. The neurons, which have been mapped with a combination of advanced techniques, also have receptors for oestrogen, which could explain why women as a group are more […]
Researchers led by Lund University in Sweden have assisted microbiologists in Ukraine in investigating bacterial resistance among the war-wounded patients treated in hospitals. The results, which were recently published in TheLancet Infectious Diseases, reveal that many of the patients were affected by bacteria that exhibited an extremely high level of antibiotic resistance. In addition to […]
Researchers discovered that the rostro-medial prefrontal specifically becomes more active when people are rejected by others at greater rates. However, individuals with BPD (characterized by interpersonal sensitivity to rejection and emotional instability) do not display rostro-medial prefrontal cortex activity when rejected. The brain reacts with rostro-medial prefrontal activity to rejection as if there is something […]
Recurrent bouts of systemic lupus erythematosus, marked by the body’s immune system attack of its own tissues, closely tracked with measureable upticks in growth in the gut of a certain species of bacteria. New research from NYU Grossman School of Medicine shows that bacterial blooms of the gut bacterium Ruminococcus blautia gnavus occurred at the […]
Researchers led by Katsunori Tanaka at the RIKEN Cluster for Pioneering Research (CPR) in Japan and Hiromitsu Haba at the RIKEN Nishina Center for Accelerator-Based Science (RNC) have developed a new technique that has the potential to generically treat several kinds of cancer, with fewer negative side effects than currently available methods. Published on June […]
Gout is the most common form of inflammatory arthritis, in which urate (a byproduct of purine-rich foods like meat and alcohol) builds up in the body and forms needle-shaped crystals in and around the joints, usually starting in the foot. The crystal deposits lead to flares of severe pain, joint swelling and tenderness, and can […]
A team of researchers have discovered that extracts from plants are able to rescue the function of ion channel proteins carrying mutations that cause human Episodic Ataxia. Individuals with ataxia exhibit abnormal gait, slurring, eye movement abnormalities, difficulties with balance and walking, tremors, and disruption of fine motor skills. “Episodic Ataxia 1 (EA1) is a […]
Clinicians have a new standard for graft-versus-host disease (GVHD) prevention after allogeneic hematopoietic stem cell transplantation, according to results from a phase III study published June 22 in the New England Journal of Medicine. The new standard is more effective at preventing GVHD and came with less side effects, compared with the current gold standard. […]
The blood-brain barrier: a layer of cells between blood vessels and the rest of the brain, kicks out toxins, pathogens and other undesirables that can sabotage the brain’s precious gray matter and its overall health. “A leaky blood-brain barrier is a common pathway for a lot of brain diseases, so to be able to seal […]
