(Press-News.org) About The Study: The results of this cohort study suggest that combining plasma p-tau217 and Aβ42/40 levels could be useful for predicting development of Aβ pathology in people with early stages of subthreshold Aβ accumulation. These biomarkers might thus facilitate screening of participants for future primary prevention trials.

MRI signature of α-synuclein pathology in asymptomatic stages and a memory clinic population
2024-07-28
About The Study: In this cohort study, seed amplification assays (SAA) α-syn+ was consistently associated with nucleus basalis of Meynert (NBM) atrophy already during asymptomatic stages. Further, in memory clinic cognitively impaired populations, SAA α-syn+ was associated with NBM atrophy, which partially mediated α-syn–induced attention/executive impairment.

Blood biomarkers to detect Alzheimer disease in primary care and secondary care
2024-07-28
About The Study: The amyloid probability score 2 (APS2) blood test and percentage of p-tau217 alone had high diagnostic accuracy for identifying Alzheimer disease among individuals with cognitive symptoms in primary and secondary care using predefined cutoff values. Future studies should evaluate how the use of blood tests for these biomarkers influences clinical care.

Changes in Alzheimer disease blood biomarkers and associations with incident all-cause dementia
2024-07-28
About The Study: Plasma biomarkers of Alzheimer disease (AD) neuropathology, neuronal injury, and astrogliosis increase with age and are associated with known dementia risk factors. AD-specific biomarkers’ association with dementia starts in midlife whereas late-life measures of AD, neuronal injury, and astrogliosis biomarkers are all associated with dementia.

New and improved drug delivery molecules for skeletal muscle
2024-07-27
Tokyo, Japan – Researchers from Tokyo Metropolitan University have created a new drug delivering molecule, a zwitterionic polymer complex that can help get plasmid DNA inside cells when injected into skeletal muscle, a crucial step in the expression of therapeutic RNA and proteins. The new compound effectively bound to plasmid DNA without affecting its structure. Injected into mouse muscles, the team observed widespread gene expression, promising applications to treatments of serious muscle diseases.
Drug delivery systems underpin many of the clinical breakthroughs of our age. For example, ...
UC San Diego Health ends negotiations with Tri-City Medical Center Healthcare District
2024-07-27
UC San Diego Health has ended more than nine months of negotiations for a potential partnership with the Tri-City Medical Center (TCMC) Healthcare District.
A final revised offer was presented to the TCMC Healthcare District on July 24 and no agreement was reached.
Highlights of the final proposal for TCMC included a financial recovery and growth plan that included:
$100 million infusion of cash within the first two years plus other financial supports, including a line of credit designed to protect the financial stability of TCMC during the first five years.
All assets and liabilities would transfer to UC San Diego Health, including employment ...
MLB add lifesavers to the chain of survival in New York City
2024-07-27
NEW YORK CITY, July 26, 2024 — The American Heart Association and Major League Baseball (MLB) brought cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) training to MLB staff at the New York headquarters office located on Avenue of the Americas on Monday, July 22. Nearly 100 employees attended to learn the lifesaving skills building confidence and capabilities to respond in the event of a cardiac emergency. According to American Heart Association data, nine out of every ten people who experience cardiac arrest outside of a hospital die, in part because they do not receive immediate CPR more than half of the time. CPR, especially if performed ...
ISU studies explore win-win potential of grass-powered energy production
2024-07-27
AMES, Iowa – Strategically planting perennial grass throughout corn and soybean fields helps address the unintended environmental consequences of growing the dominant row crops, including soil erosion, fertilizer runoff and greenhouse gas emissions.
But converting portions of farmland back to prairie has to make financial sense for farmers, which is why a research team led by Iowa State University landscape ecologist Lisa Schulte Moore has spent the past six years studying how to efficiently turn harvested ...
Study identifies biomarker that could predict whether colon cancer patients benefit from chemotherapy
2024-07-27
MIAMI, FLORIDA (July 25, 2024) – Many people with stage II or III colon cancer receive additional, or adjuvant, chemotherapy following surgery. However, clinical trials have shown that this treatment doesn’t improve the chances of survival for every patient. A study published July 25 in Cell Reports Medicine identifies and validates a 10-gene biomarker that potentially predicts whether a stage II or III colon cancer patient will benefit from adjuvant chemotherapy.
A secondary finding from the study could also lead to further research and application. Researchers found that the gene signature could potentially also predict ...
Children are less likely to have type 1 diabetes if their mother has the condition than if their father is affected
2024-07-27
New research to be presented at this year’s Annual Meeting of the European Association for the Study of Diabetes (EASD) (Madrid, 9-13 September) shows that a child is almost twice as likely to develop type 1 diabetes (T1D) if their father has the condition, than if their mother has the condition.
The study, the largest of its kind, suggests that exposure to T1D in the womb confers long-term protection against the condition in children with affected mothers relative to those with affected fathers.
Understanding what is responsible for this relative protection could lead to opportunities ...
Two shark species documented in Puget Sound for first time by Oregon State researchers
2024-07-26
CORVALLIS, Oregon – Oregon State University researchers have made the first scientific confirmation in Puget Sound of two distinct shark species, one of them critically endangered.
The presence of the broadnose sevengill shark and endangered soupfin shark in the sound, the southern portion of the Salish Sea, may indicate changes in what biologists in OSU’s Big Fish Lab describe as an economically, culturally and ecologically valuable inland waterway.
The Salish Sea separates northwest Washington from British Columbia’s Vancouver Island. The ...
