Consumption of ultraprocessed food and risk of depression

JAMA Network Open

2023-09-20

(Press-News.org) About The Study: The findings of this study suggest that greater ultraprocessed food (UPF; i.e., energy-dense, palatable, and ready-to-eat items) intake, particularly artificial sweeteners and artificially sweetened beverages, is associated with increased risk of depression. Although the mechanism associating UPF to depression is unknown, recent experimental data suggests that artificial sweeteners elicit purinergic transmission in the brain, which may be involved in the etiopathogenesis of depression.

Surrogate adiposity markers and mortality

2023-09-20

About The Study: Waist-to-hip ratio had the strongest and most consistent association with mortality irrespective of body mass index in this study consisting of 387,000 UK adult participants from the UK Biobank. Clinical recommendations should consider focusing on adiposity distribution compared with mass. Authors: Guillaume Pare, M.D., M.Sc., of the Vascular and Stroke Research Institute in Hamilton, Ontario, Canada, is the corresponding author.

Strengthening artificial immune cells to fight cancer

2023-09-20

Among available immunotherapies, the use of «CAR-T» cells is proving extremely effective against certain blood cancers, but only in half of patients. A main reason for this is the premature dysfunction of these immune cells, which have been artificially modified in vitro. A team from the Universities of Geneva (UNIGE), Lausanne (UNIL), the Geneva University Hospitals (HUG) and the Vaud University Hospital (CHUV), all part of the Swiss Cancer Center Léman (SCCL), has discovered how to prolong the functionality of CAR-T cells. By inhibiting a very specific metabolic mechanism, the team has succeeded ...

Prehistoric fish fills 100 million year gap in evolution of the skull

2023-09-20

A 455-million-year-old fossil fish provides a new perspective on how vertebrates evolved to protect their brains, a study has found. In a paper published in Nature today (Wednesday 20th September), researchers from the University of Birmingham, Naturalis Biodiversity Centre in Leiden, Netherlands; and the Natural History Museum have pieced together the skull of Eriptychius americanus. The research, funded by the Leverhulme Trust, suggests that the ancient jawless fish found in ancient deposits in ...

Study finds firearm injuries increased in gentrified neighborhoods

2023-09-20

Brigham researchers reported that gentrified neighborhoods had a 62 percent higher firearm injury incidence rate than non-gentrified communities with comparable sociodemographic characteristics Understanding the reason for this increase is vital to reducing future firearm injuries Gentrification can have a ripple effect on communities. While it can improve certain conditions in typically low-income areas, rising housing costs can displace residents, causing social disruption and other downstream effects. Investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, conducted a study using national data to examine the relationship ...

Scientists reveal how the effects of psychosis spread throughout the brain

2023-09-20

Psychoses like schizophrenia cost billions of dollars annually and derail the lives of people struggling with the disease. Now Monash University researchers have modelled how the effects of psychosis spread through the brain, allowing them to isolate areas where these changes may originate from and which could be targeted by therapies designed to reduce the disease’s progression. The study, published today in the prestigious Journal of the American Medical Association Psychiatry, details how the scientists were able to map and model the spread of brain changes in people with different stages of psychoses such as schizophrenia,from people newly ...

Decoding depression: Researchers identify crucial biomarker that tracks recovery from treatment-resistant depression

2023-09-20

A team of leading clinicians, engineers, and neuroscientists has made a groundbreaking discovery in the field of treatment-resistant depression. By analyzing the brain activity of patients undergoing deep brain stimulation (DBS), a promising therapy involving implanted electrodes that stimulate the brain, the researchers identified a unique pattern in brain activity that reflects the recovery process in patients with treatment-resistant depression. This pattern, known as a biomarker, serves as a measurable indicator of disease recovery and represents a significant ...

CityU researchers develop novel photo-oxidation therapy for anticancer treatment

2023-09-20

A research team led by scientists from City University of Hong Kong (CityU) has achieved a significant breakthrough by inventing a new class of near-infrared-activated photo-oxidants that can effectively kill cancer cells without requiring oxygen. The photo-oxidants induce a unique form of cancer cell death that can overcome cancer cell resistance. The findings offer a new strategy, called ‘photo-oxidation therapy’, and provide a promising direction for the development of anti-cancer drugs. Photodynamic therapy, an innovative ...

Awardees may be eligible for a third year of funding. Sarcoidosis is an inflammatory ...

Zhijian ‘James’ Chen and Glen Barber awarded Horwitz prize for discovering the cGAS-STING pathway

2023-09-20

NEW YORK, NY (September 20, 2023)—Columbia will award the 2023 Louisa Gross Horwitz Prize to Zhijian ‘James’ Chen and Glen Barber for discovering the cGAS-STING pathway, a key component of one of the body’s first line of defenses, the innate immune system. When pathogens infiltrate our cells, they leave behind traces of their DNA. These molecular fingerprints are detected by our cGAS-STING pathway, which sounds the alarm and mobilizes the immune system to eliminate invading threats. Research on the cGAS-STING pathway has revealed the ...
