Cancer cachexia (CC) is marked by severe skeletal muscle loss and dysfunction, associated with mitochondrial degeneration. Our previous studies showed induction of the mitophagy marker BNIP3 3-wk post-Lewis lung carcinoma (LLC) induction. We hypothesize that excessive mitophagy contributes to muscle wasting in CC. To test this, we used a Bnip3 knockout (KO) mouse model with LLC-induced CC to assess its impact on muscle outcomes. Eight-wk-old male and female mice were injected with 1 x 10(6) LLC cells or PBS (sham controls). After 4 wk, we assessed muscle function through dorsiflexor electrophysiology, muscle protein synthesis via deuterium oxide labeling, and mitochondrial …

Electro Transcranial Magnetic Stimulation (Etms) Effects On Pharmacoresistent Sleep Disorders Using A Quantitative Electroencephalogram (Qeeg), Sarah Diane Dean

Doctoral Dissertations and Projects

The following quantitative correlational study investigated the effects of eTMS on individuals with pharmacoresistant sleep disorders using a qEEG. This research measures the dimensions of anxiety, depression and quality of life (QoL) as it relates to untreated secondary diagnosis. Additionally, this research examines the activity level of the dorsolateral prefrontal cortex in relation to eTMS treatments. It was found that correlation with anxiety (rs = -.466, p < .001), depression (rs = -0.556, p < 0.001), quality of life (rs = -.436, p < .001), and sleep disturbances (rs = -0.452, p < 0.001), have a statistically significant negative correlation with dlPFC activity level. Finally, it was found that eTMS does have a statistically significant relationship with sleep disturbances as well as anxiety, depression and general quality of life (U (195) = 4647, p = .971). This is important to the field of neuroscience as it provided a more precise form of individualized neuromodulation through the use of a uncommon type of transcranial magnetic stimulation.

The Role Of Neuroscience In Mental Health Management Within The Adhd Population, Kadi Rae Smith

University Honors Theses

Neuroscience-based educational interventions play a role in the management of Attention Deficit Hyperactive Disorder (ADHD), including the regulation of ADHD-correlated depression and anxiety. Existing research shows that elevated rates of depression correspond to anxiety within the ADHD community; approximately 8.83% of the global population. Social ostracization and isolation are established contributors to depression and anxiety which are commonly comorbid with ADHD. The need exists for further investigation of the beneficial impact that an accurate, biological understanding of how the brain works has on the mental health of the ADHD population, and by extension their families, education systems, and medical industries. …

The nucleolus is a membraneless organelle and an excellent stress sensor. Any changes in its architecture or composition lead to nucleolar stress, resulting in cell cycle arrest and interruption of ribosomal activity, critical factors in aging and cancer. In this study, we identified and described the pivotal role of the RNA-binding protein HNRNPK in ribosome and nucleolar dynamics. We developed an in vitro model of endogenous HNRNPK overexpression and an in vivo mouse model of ubiquitous HNRNPK overexpression. These models showed disruptions in translation as the HNRNPK overexpression caused alterations in the nucleolar structure, resulting in p53-dependent nucleolar stress, cell …

Disturbances from insect pests threaten ecologically and economically important goods and services supplied by forests, including wood production and carbon sequestration. We highlight the factors that influence these services’ resistance, a term quantifying the initial response to disturbance. Insects inflict damage through a range of mechanisms, prompting distinct plant physiological responses that scale to influence ecosystem processes and, with time, goods and services. The degree and timing of tree mortality and defoliation affect the amount of residual vegetation available to support compensatory wood production and influence carbon sequestration by changing rates of detritus-fueled decomposition. Compounding, or sequential, insect attacks may …

Sinaya: A Philippine Journal for Senior High School Teachers and Students

Coral reefs are vulnerable to disruptive human activities such as pollution, overfishing, and coastal development—degrading water quality and reef structures. Active reef restoration entails temporarily relocating several corals to aquaculture facilities to achieve successful rehabilitation; however, current coral transport methods pose certain risks, such as stress-induced mortality, which can result from physical damage during transportation. Existing studies on coral transport have explored various techniques for collecting, shipping, and maintaining live coral specimens. The design consists of petal-shaped areas where the waves gather, akin to a coral reef’s grooves, separated by wedges—the spurs—that cause waves to divide. The different design modifications …

Type I interferons (IFNs-I), a group of pleiotropic cytokines, critically modulate host response in various inflammatory diseases. However, the role of the IFN-I pathway in periodontitis remains largely unknown. In this report, we describe that the IFN-β levels in the gingival crevicular fluid of human subjects were negatively associated with periodontitis and clinical gingival inflammation. Disruption of IFN-I signaling worsened alveolar bone resorption in a ligature-induced periodontitis murine model. Deficiency of the IFN-I pathway resulted in an exaggerated inflammatory response in myeloid cells and drastically increased the interleukin-17 (IL-17)-mediated neutrophil recruitment in the gingiva. We further identified that the myeloid …

Macrophage Heterogeneity And Function In The Lung, Xin Li

Dartmouth College Ph.D Dissertations

Macrophages are critical custodians of the lung, orchestrating immune surveillance, maintaining tissue homeostasis, and coordinating both innate and adaptive responses. This dissertation examines their heterogeneity and specialized functions, focusing on IMs, which reside in the lung interstitium, and AMs, which occupy the airspace. Through comprehensive single-cell transcriptomic profiling of murine and human samples, we identify multiple IM and AM subsets defined by distinct chemokine, cytokine, receptor, and innate immune gene signatures. These subsets display clear divisions of labor, contributing to immune cell recruitment, tertiary lymphoid structure formation, and alveolar homeostasis.

In IMs, coordinated chemokine programs not only recruit inflammatory cells …

A novel nanocomposite of polyvinyl alcohol formaldehyde (PVF) sponge loaded with green zinc oxide nanoparticles (ZnONP) and referred to as (NP-PVF) was fabricated as a potential adsorbent of ciprofloxacin from water. A simple mechanical foaming process was used to synthesize the adsorbent. Rice husk extract was used to synthesize zinc oxide nanoparticles (ZnONP) for its phytochemicals as reducing agents. A facile and low-energy-dependent extraction method was used that did not require the use of high-temperature annealing. The synthesized nanoparticles showed a maximum UV absorption at 347 nm, which corresponds to a 3.58 eV band gap energy. FTIR confirmed the successful …

Human-wildlife conflict is a widespread challenge faced by those living in regular contact with wildlife that can have profound impacts on livelihood outcomes for humans, wildlife, and their shared environment (Barua et al., 2013; Blackie, 2023). Human – non-human primate conflict is particularly crucial due to primates’ high capacity to live among human populations (Chapman & Chapman, 1990; Alberts & Altmann, 2006; Reader et al., 2011; Sinha & Vijayakrishnan, 2017), and is currently on the rise due to increasing contact between human and non-human primates (Hockings, 2016; Uddin et al., 2020). To characterize and analyze techniques currently being used to …
