The number of neural stem cells in the brain decreases with age, which in the dentate gyrus of older mice is associated with a lower SIRT7-mediated mitochondrial unfolded protein response and reduced neural stem cell maintenance and neurogenesis. The study found elevated blood glucose and increased sugar intake can lead to the proliferation of amyloid plaques in the brain - a characteristic sign of Alzheimer's. By reconstructing the complete dendrites and axons for nearly 2,000 neurons in PFC, Gao et al. With more research it would be possible to identify a genetic trajectory that could point to a gut microbiome that would be more or less prone to developing diseases such as Alzheimers, said study lead author and UNLV graduate student Davis Cammann, but we also have to remember that the gut biome is influenced by many factors including lifestyle and diet., Author: Keyonna SummersSource: University of Nevada Las VegasContact: Keyonna Summers University of Nevada Las VegasImage: The image is credited to Neuroscience News, Original Research: Open access.Genetic correlations between Alzheimers disease and gut microbiome genera by Jingchun Chen et al.

Research Highlight #1 - Reduced Oxygen Intake Linked to Extended Lifespan A fascinating study demonstrates a link between reduced oxygen intake and extended lifespan in mice. To fight or not to fight? The study found a significant correlation between 10 specific types of gut bacteria and the likelihood of developing Alzheimers disease. Certain bacteria in the human gut can secrete acids and toxins that interact with the APOE gene, a major risk factor for Alzheimers disease, triggering a neuroinflammatory response that can affect brain health and immune functions. The researchers have discovered that the compound has a dual effect, and is also able to protect myelin. Certain bacteria in humans guts can secrete acids and toxins that thin and seep through the intestinal lining, interact with theAPOE(a gene identified as a major risk factor for Alzheimers disease), and trigger a neuroinflammatory response affecting brain health and numerous immune functions, and potentially promoting development of the neurodegenerative disorder.

The authors show that inactivation of the microglial cGASinterferon axis confers such resilience by preserving the neuronal expression of myocyte enhancer factor 2c. They deliberated for extended durations, approximated efficient computational algorithms for managing complexity, and even selected algorithms according to the computational complexity of the trial. 01 May 2023. A study by Columbia University has found that overactive mitochondria provide the additional energy that up to 20% of glioblastomas require to survive, suggesting a potential new treatment option for these cancers. In this study, the authors found that endocannabinoid postsynaptic release is mediated by synucleins via a synuclein-dependent and SNARE-dependent mechanism. Spontaneous chronic pain states were predicted most reliably by sustained changes in the activity of the orbitofrontal cortex, whereas acute pain was most associated with signals from the anterior cingulate cortex. Article provide evidence that human neurodevelopment unfolds along a hierarchical cortical axis from childhood to adolescence and demonstrate how environmental influences on the maturing brain are shaped by this developmental program. 5812 South Ellis Ave. Open Access. Using the chronic brain recordings in the anterior cingulate cortex and orbitofrontal cortex in four participants with intractable chronic pain, this study identified objective neural biomarkers of subjective pain experience.

Six categories of bacteria Adlercreutzia, Eubacterium nodatum group, Eisenbergiella, Eubacterium fissicatena group, Gordonibacter,andPrevotella9 were identified as protective, and four types of bacteria Collinsella, Bacteroides, Lachnospira,andVeillonella were identified as a risk factor for Alzheimers disease. While their analysis established overarching categories of bacteria typically associated with Alzheimers disease, the UNLV team said further research is needed to drill down into the specific bacterial species that influence risk or protection. The hope is to one day develop treatments that are customized for an individual patient and their genetic makeup, such as medications or lifestyle change. 2-Microglobulin (2M) is an amyloidogenic protein. This discovery opens up avenues to explore the lifestyle and health conditions that may be linked to superior cognition in the elderly. Two monkeys solved combinatorial optimization problems for rewards. Key Facts: The AI-based method developed can predict with 91% accuracy whether an enzyme can work with a specific molecule. The analysis revealed that an imbalance of gut bacteria can have negative effects on the immune system and is linked to various diseases, including depression, heart disease, cancer, and Alzheimers disease.
