Unveiling Novel Avenues In Mtor-Targeted Therapeutics: Advancements In Glioblastoma Treatment, Shilpi Singh, Debashis Barik, Karl Lawrie, Iteeshree Mohapatra, Sujata Prasad, Afsar R. Naqvi, Amar Singh, Gatikrushna Singh

Biology Student Work

The mTOR signaling pathway plays a pivotal and intricate role in the pathogenesis of glioblastoma, driving tumorigenesis and proliferation. Mutations or deletions in the PTEN gene constitutively activate the mTOR pathway by expressing growth factors EGF and PDGF, which activate their respective receptor pathways (e.g., EGFR and PDGFR). The convergence of signaling pathways, such as the PI3K-AKT pathway, intensifies the effect of mTOR activity. The inhibition of mTOR has the potential to disrupt diverse oncogenic processes and improve patient outcomes. However, the complexity of the mTOR signaling, off-target effects, cytotoxicity, suboptimal pharmacokinetics, and drug resistance of the mTOR inhibitors pose …

Facial Motion Augmented Identity Verification With Deep Neural Networks, Zheng Sun

Theses and Dissertations

Identity verification is ubiquitous in our daily life. By verifying the user's identity, the authorization process grants the privilege to access resources or facilities or perform certain tasks. The traditional and most prevalent authentication method is the personal identification number (PIN) or password. While these knowledge-based credentials could be lost or stolen, human biometric-based verification technologies have become popular alternatives in recent years. Nowadays, more people are used to unlocking their smartphones using their fingerprint or face instead of the conventional passcode. However, these biometric approaches have their weaknesses. For example, fingerprints could be easily fabricated, and a photo or …

#1 On The U.S. Most Wanted List: Why The Push Is On To Ban The World’S Most Successful Startup From Academic, Government And Military Devices In The United States, Tom Waters

GNSI Publications

TikTok is a social media application that has amassed over 100 million users in the United States. Yet the Biden White House, like the Trump Administration before it, seeks to ban TikTok, or at least force it’s divestment from the parent company, Bytedance. For many the question is how can an app for sharing silly dance videos among teenagers be a national security threat? Unfortunately, the problem is considerably more complex than this simple question. TikTok’s unprecedented success comes from its powerful artificial intelligence-based algorithm.

That activity produces a comprehensive psychological profile of each user and tailors the queue of …

Mabini Review

One of the most celebrated personalities in the political arena, both domestically and internationally, is the 7th President of the Philippines Ramon del Fierro Magsaysay Sr., Most known as “My Guy.” He gained mass support and almost a cult-of-personality status thanks to his unique campaign jingle, “Mambo Magsaysay,” composed by Sen. Raul Manglapus in 1953. Despite holding the highest position in government, he is remembered as a president who look for and cared for the Common tao (common people) due to his down-to-earth personification. Tracing roots into his humble begginings being raised in simple way of life in the town …

Continuous Spin Excitations In The Three-Dimensional Frustrated Magnet K2ni2 (So4)3, Weiliang Yao, Qing Huang, Tao Xie, Andrey Podlesnyak, Alexander Brassington, Chengkun Xing, Ranuri S.Dissanayaka Mudiyanselage, Haozhe Wang, Weiwei Xie, Shengzhi Zhang, Minseong Lee, Vivien S. Zapf, Xiaojian Bai, D. Alan Tennant, Jian Liu, Haidong Zhou

Faculty Publications

Continuous spin excitations are widely recognized as one of the hallmarks of novel spin states in quantum magnets, such as quantum spin liquids (QSLs). Here, we report the observation of such kind of excitations in K2Ni2(SO4)3, which consists of two sets of intersected spin-1 (Ni2+) trillium lattices. Our inelastic neutron scattering measurement on single crystals clearly shows a dominant excitation continuum, which exhibits a distinct temperature-dependent behavior from that of spin waves, and is rooted in strong quantum spin fluctuations. Further using the self-consistent-Gaussian-approximation method, we determine that the fourth- and fifth-nearest-neighbor exchange interactions are dominant. These two bonds together …

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

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

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 …
