How To Treat Alzheimer’S Disease By Boosting Glymphatic Flow: Simulations In A New Computational Model, Charles F. Babbs Oct 2023

How To Treat Alzheimer’S Disease By Boosting Glymphatic Flow: Simulations In A New Computational Model, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

This study exercises a new mathematical model to search for unappreciated therapeutic targets in Alzheimer’s disease. The model describes detailed mechanisms underlying the glymphatic pump mechanism, which removes toxic proteins of Alzheimer’s disease from the interstitial fluid of the brain. It shows that the glymphatic pump is driven by the amplitude of intracranial pressure pulsations in the subarachnoid space, which are correlated with the arterial pulse and modulated by many other factors. Implementing ways to increase intracranial pressure pulses quickly comes to mind as a potential treatment strategy. Specific interventions include drugs that increase arterial pulse volume and small devices …

Deleuze’S Nietzsche: Life, Critique, And Difference, Dr. Raniel Reyes Oct 2023

Deleuze’S Nietzsche: Life, Critique, And Difference, Dr. Raniel Reyes

Mabini Review

In this article, I re-visit and navigate Nietzsche’s concepts of genealogy, will to power, and the eternal return through the lens of Gilles Deleuze’s philosophy. Nietzschean philosophy occupies a significant part in the preliminary blueprints of Deleuze’s philosophy of difference, which relatively encompasses even his collaborative scholarship with Guattari. Hence, this research likewise diagrams some critical affinities between Nietzsche and Deleuze, in conjunction with other contemporary thinkers and issues. My disquisition of the aphorism as a philosophical style and genealogy grounds my engagement with the principles of will to power and the eternal return. Through the evaluative aptitude of the …

Dissecting The Daily Feeding Pattern: Peripheral Clock/Cycle Generate The Feeding/Fasting Episodes And Neuronal Molecular Clocks Synchronize Them, Akiko Maruko, Koichi M Iijima, Kanae Ando Oct 2023

Dissecting The Daily Feeding Pattern: Peripheral Clock/Cycle Generate The Feeding/Fasting Episodes And Neuronal Molecular Clocks Synchronize Them, Akiko Maruko, Koichi M Iijima, Kanae Ando

Department of Neuroscience Faculty Papers

A 24-h rhythm of feeding behavior, or synchronized feeding/fasting episodes during the day, is crucial for survival. Internal clocks and light input regulate rhythmic behaviors, but how they generate feeding rhythms is not fully understood. Here we aimed to dissect the molecular pathways that generate daily feeding patterns. By measuring the semidiurnal amount of food ingested by single flies, we demonstrate that the generation of feeding rhythms under light:dark conditions requires quasimodo (qsm) but not molecular clocks. Under constant darkness, rhythmic feeding patterns consist of two components: CLOCK (CLK) in digestive/metabolic tissues generating feeding/fasting episodes, and the …

Solving Geospatial Problems Under Extreme Time Constraints: A Call For Inclusive Geocomputational Education, Coline C. Dony Oct 2023

Solving Geospatial Problems Under Extreme Time Constraints: A Call For Inclusive Geocomputational Education, Coline C. Dony

I-GUIDE Forum

To prepare our next generation to face geospatial problems that have extreme time constraints (e.g., disasters, climate change) we need to create educational pathways that help students develop their geocomputational thinking skills. First, educators are central in helping us create those pathways, therefore, we need to clearly convey to them why and in which contexts this thinking is necessary. For that purpose, a new definition for geocomputational thinking is suggested that makes it clear that this thinking is needed for geospatial problems that have extreme time constraints. Secondly, we can not further burden educators with more demands, rather we should …

I-GUIDE Forum

In this paper, we propose a new form of multidisciplinary academic collaboration that goes beyond the traditional modes of knowledge exchange. We argue that most research collaboration today is based on interactions between closely related disciplines, in which researchers share data, methods, and insights within a common framework or problem. However, such collaboration may not foster the development of the communication and management skills essential to a multi-disciplinary research career. Therefore, we suggest establishing a network of researchers from divergent, yet complementary, disciplines who are interested in improving these skills through regular interactions and feedback. The main goal of this …
