This article presents the original descriptions of some recent physics mechanisms (based on the thermodynamic, kinetic, and quantum tunnel effects) providing stable 2H/1H isotope fractionation, leading to the accumulation of particular isotopic forms in intra- or intercellular space, including the molecular effects of deuterium interaction with 18O/17O/16O, 15N/14N, 13C/12C, and other stable biogenic isotopes. These effects were observed mainly at the organelle (mitochondria) and cell levels. A new hypothesis for heavy nonradioactive isotope fractionation in living systems via neutron effect realization is discussed. The c...

In conclusion, melatonin ameliorates memory deficits in STZ-induced hyperglycemia rats by restoring insulin signaling pathway which is independent of its effects on blood glucose and insulin levels. Thus, melatonin might be a therapeutic option for helping patients suffering from diabetes and contributed to Alzheimer's disease.

Authors: Kim YG, Park DG, Moon SY, Jeon JY, Kim HJ, Kim DJ, Lee KW, Han SJ Abstract BACKGROUND: Type 2 diabetes mellitus (T2DM) is associated with an increased risk for dementia. The effects of hypoglycemia on dementia are controversial. Thus, we evaluated whether hypoglycemia increases the risk for dementia in senior patients with T2DM. METHODS: We used the Korean National Health Insurance Service Senior cohort, which includes>10% of the entire senior population of South Korea. In total, 5,966 patients who had ever experienced at least one episode of hypoglycemia were matched with those who had not, using p...

Authors: Verma N, Despa F Abstract The link of diabetes with co-occurring disorders in the brain involves complex and multifactorial pathways. Genetically engineered rodents that express familial Alzheimer's disease-associated mutant forms of amyloid precursor protein and presenilin 1 (PSEN1) genes provided invaluable insights into the mechanisms and consequences of amyloid deposition in the brain. Adding diabetes factors (obesity, insulin impairment) to these animal models to predict success in translation to clinic have proven useful at some extent only. Here, we focus on contributing factors to diabetic brain in...

CONCLUSION: We propose that it is now necessary to consider whether neuroinflammation in Alzheimer's disease affects inflammation in the pancreas related to diabetes. PMID: 31692443 [PubMed - as supplied by publisher]

NIH Neuroscience Series Seminar Dr. DiAntonio ’ s laboratory investigates molecular mechanisms that control the structure and function of neural circuits in development and disease. They combine genetic, molecular, neuroanatomical, and electrophysiological studies in both Drosophila and mouse to identify pathways required for the development, maintenance, and regeneration of axons and synapses. Axonal degeneration is a common feature of many neurological diseases including hereditary neuropathies, diabetes, glaucoma, chemotherapy-induced neurotoxicity, and neurodegenerative diseases such as Alzheimer ’ s and Pa...

In this study, we hypothesized that moderately and chronically reducing ACh could attenuate the deleterious effects of aging on NMJs and skeletal muscles. To test this hypothesis, we analyzed NMJs and muscle fibers from heterozygous transgenic mice with reduced expression of the vesicular ACh transporter (VAChT), VKDHet mice, which present with approximately 30% less synaptic ACh compared to control mice. Because ACh is constitutively decreased in VKDHet, we first analyzed developing NMJs and muscle fibers. We found no obvious morphological or molecular differences between NMJs and muscle fibers of VKDHet and contro...

The ER is a large multifunctional organelle of eukaryotic cells. Malfunction of the ER in various disease states, such as atherosclerosis, diabetes, cancer, Alzheimer’s and Parkinson’s and amyotrophic lateral sclerosis, often correlates with alterations in its morphology. The ER exhibits regionally variable membrane morphology that includes, at the extremes, large relatively flat surfaces and interconnected tubular structures highly curved in cross-section. ER morphology is controlled by shaping proteins that associate with membrane lipids. To investigate the role of these lipids, we developed a sea urchin oocy...
