Published Molecular imaging identifies brain changes in response to food cues; offers insight into obesity interventions
(via sciencedaily.com) Original source Molecular imaging with 18F-flubatine PET/MRI has shown that neuroreceptors in the brains of individuals with obesity respond differently to food cues than those in normal-weight individuals, making the neuroreceptors a prime target for obesity treatments and therapy. This research contributes to the understanding of the fundamental mechanisms underlying obesity and offers valuable insights into potential medical interventions.
Published Follow the leader: Researchers identify mechanism of cancer invasion
(via sciencedaily.com) Original source A cancerous tumor is the accumulation of cells uncontrollably dividing, some of which can invade other parts of the body. The process is difficult to predict in detail, and eradicating the cells poses even greater difficulty. Now, a research team has revealed how the exodus initiates, shedding light on a potential therapeutic target to halt the invasion and providing a prognostic marker to help clinicians select the best treatment option.
Published Poor sense of smell linked to increased risk of depression in older adults
(via sciencedaily.com) Original source 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.
Published Lean body mass, age linked with alcohol elimination rates in women
(via sciencedaily.com) Original source Research links women's lean body mass with how quickly they eliminate alcohol from their system. Women with obesity and those who are older eliminate alcohol from their bloodstreams faster than those of normal weight and those who are younger.
Published Pain not perceived in the same way in people with Alzheimer's Disease
(via sciencedaily.com) Original source New research has found that in a mouse model mimicking Alzheimer's Disease (AD) pain signals are not processed in the same way as in healthy mice.
Published Loss of Y chromosome in men enables cancer to grow
(via sciencedaily.com) Original source As men age, some of their cells lose the very thing that makes them biological males -- the Y chromosome -- and this loss hampers the body's ability to fight cancer, according to new research. The study found that loss of the Y chromosome helps cancer cells evade the body's immune system. This common impact of the aging process in men results in aggressive bladder cancer, but somehow also renders the disease more vulnerable -- and responsive -- to a standard treatment called immune checkpoint inhibitors.
Published New findings show mitochondrial DNA fragments in blood as important biomarkers for aging and inflammation
(via sciencedaily.com) Original source In an eight-year study of more than 600 community-dwelling older adults, researchers say they have further linked levels of cell-free DNA (DNA fragments resulting from cell death) circulating in the blood to chronic inflammation and frailty. The study is novel and expands on previous work, the investigators say, because it focused on mitochondrial DNA rather than solely genomic DNA, as previously reported.
Published Close up on aging reveals how different cell types in the body age at different pace
(via sciencedaily.com) Original source A team or researchers reports the first Aging Fly Cell Atlas (AFCA), a detailed characterization of the aging process in 163 distinct cell types in the laboratory fruit fly. Their in-depth analysis revealed that different cell types in the body age differently, each cell type following a process involving cell type-specific patterns. AFCA provides a valuable resource for researchers in the fruit fly and aging communities as a reference to study aging and age-related diseases and to evaluate the success of anti-aging strategies.
Published Ultra small molecule as a new target for Alzheimer's disease?
(via sciencedaily.com) Original source A new study shows that a very small molecule called microRNA-132 can have a significant impact on different brain cells and may play a role in Alzheimer's disease.
Published Fewer meals may prevent Type 2 diabetes, obesity
(via sciencedaily.com) Original source When intermittent fasting became all the rage among Hollywood celebrities, skeptics balked at the idea of skipping meals. But new research suggests the celebs might not have been that far off. The review found that a specific type of restricted eating may reduce the chances of developing Type 2 diabetes and improve your overall health. Known as time-restricted eating, this type of fasting means having regular but fewer meals, cutting out late-night snacks and not eating for 12 to 14 hours (often overnight).
Published Altered gut bacteria may be early sign of Alzheimer's disease
(via sciencedaily.com) Original source Alzheimer's disease causes changes to the brain that begin two decades or more before symptoms appear. A study reveals that the bacteria that live in the gut also change before Alzheimer's symptoms arise, a discovery that could lead to diagnostics or treatments for Alzheimer's disease that target the gut microbiome.
Published The latest weapon against cancer is ... a keto diet?
(via sciencedaily.com) Original source Keto diets shrink pancreatic and colorectal tumors by starving them of the glucose they need to survive. But they also speed up development of a lethal wasting disease called cachexia. In mice, researchers have found that pairing keto with a corticosteroid prevents cachexia and increases survival.
Published Taurine may be a key to longer and healthier life
(via sciencedaily.com) Original source A study finds that deficiency of taurine, a molecule produced in our bodies, drives aging, and taurine supplements can improve health and increase lifespan in animals.
Published The IL-17 protein plays a key role in skin aging
(via sciencedaily.com) Original source A team of scientists has discovered that IL-17 protein plays a central role in skin aging. The study highlights an IL-17-mediated ageing process to an inflammatory state.
Published How chronic stress drives the brain to crave comfort food
(via sciencedaily.com) Original source Stress can override natural satiety cues to drive more food intake and boost cravings for sweets.
Published A chance observation finds potential hearing biomarker for Alzheimer's disease
(via sciencedaily.com) Original source Researchers found where plaques are found in the brain may impact hearing in Alzheimer's disease.
Published Sea cucumbers: The marine delicacy that can deter diabetes
(via sciencedaily.com) Original source They're a marine delicacy loved across Asia, but the humble sea cucumber is also proving to be a key ingredient in preventing diabetes, according to new research.
Published Poorly insulated nerve cells promote Alzheimer's disease in old age
(via sciencedaily.com) Original source Researchers have shown that defective myelin actively promotes disease-related changes in Alzheimer's disease.
Published Why do some people live to be 100? Intestinal bacteria may hold the answer
(via sciencedaily.com) Original source Some people live longer than others -- possibly due to a unique combination of bacteria in their intestines, new research concludes.
Published Tracking early signs of Alzheimer's pathology in a mouse model
(via sciencedaily.com) Original source About two-thirds of the risk for Alzheimer's disease (AD) is thought to arise from genetic influences, but about a third could be influenced by environment and lifestyle, opening the door for behavioral interventions that could delay or prevent pathophysiological changes that occur with AD. Now a new study in a mouse model of AD examines the effects of environmental enrichment on AD symptom progression and pathology.
