Berries In Baskets Versus Apples In Crates: Arguing For Ecocentrism In A Post-Covid World, Abhik Gupta
Budhi: A Journal of Ideas and Culture
The global outbreak of COVID-19 has raised questions about human relationships with nature vis-à-vis development models that are largely followed worldwide. Conservation biologist Raymond F. Dasmann introduced the concept of “ecosystem people” to describe predominantly rural communities who largely depend on the resources available in one or a few ecosystems around them. These societies are also characterized by their close relationships with nature and their ecocentric worldviews. However, the world today is dominated by “biosphere people” who populate the urban areas and typically use resources extracted from all over the world. This biosphere model of existence has also given rise …
Relational Egalitarianism And The Covid-19 Pandemic, Jacqueline Marie J. Tolentino
Relational Egalitarianism And The Covid-19 Pandemic, Jacqueline Marie J. Tolentino
Budhi: A Journal of Ideas and Culture
The current COVID-19 pandemic has called for unprecedented measures to contain it and, as such, has reinforced and produced complex and intertwining health and non-health inequalities. I take the perspective of relational egalitarianism and argue that these inequalities are not only issues of public health and economics but also of social justice. I thus aim to construct a relational egalitarian framework to examine how and why the inequalities of COVID-19 are unjust and to work out what structural changes and processes might be required to justly respond to these inequalities.

Normalizing The Population: The Biopolitics Of The "New Normal", Federico José T. Lagdameo
Budhi: A Journal of Ideas and Culture
While the whole world is trying to get its bearings in the face of the radical changes brought about by the COVID-19 pandemic, two prevailing attitudes or approaches have emerged: (1) a yearning for a return to pre-COVID-19 normalcy typified by what I call the “typhoon-shelter approach” and (2) recognizing the irreversibility of the current condition and seeking to establish a “new normal.” The biopolitical analysis employed in this paper reveals unintended consequences that slip through the mesh of traditional forms of critique centered on capital, ideology, or class conflict. Specifically, the “new normal” project prevents the free movement of …

Accumbal Plasticity And Associated Behavioral Adaptations In The Spared Nerve Injury Model Of Chronic Neuropathic Pain, Yu-Hsuan Chang
Arts & Sciences Electronic Theses and Dissertations
Chronic pain is a debilitating neurological disorder that affects hundreds of millions of individuals worldwide. It is associated with cognitive symptoms such as cognitive inflexibility, which is defined as the inability to adaptively update behavior in response to changing environmental conditions. To date, there are no effective treatments for these symptoms, even though they substantially contribute to the decreased quality of life of chronic pain patients and are associated with reduced efficacy of pain management strategies. Therefore, understanding the neural circuit adaptations that drive cognitive symptoms of chronic pain, like cognitive inflexibility, is essential for improving existing treatments for this …

First Records Of The Spider Wasp Entypus Ochrocerus Dahlbom (Hymenoptera: Pompilidae: Pepsinae) From The Continental United States, Jamaica, And The Bahamas, Frank E. Kurczewski, Rick C. West, Dionne Newell, Scott Johnson
Insecta Mundi
A small population of Entypus ochrocerus Dahlbom, a predominantly Greater Antilles spider wasp (Hymenoptera: Pompilidae: Pepsinae), is reported for the first time from the continental United States based on photographs and associated information from iNaturalist.org. The species was initially misidentified online as E. unifasciatus unifasciatus (Say) or Entypus sp. However, Entypus u. unifasciatus individuals from east of the 100th Meridian in the United States typically have melanochromatic (dark) wings with a subapical xanthochromatic (orange-amber) patch. Entypus ochrocerus from Miami-Dade County, Florida is differentiated from E. u. unifasciatus by its black body with dark greenish blue reflections …

The Puzzling Distribution Of Platphalonidia Aenigmana, New Species, From The Western U. S. A. And Colombia (Lepidoptera: Tortricidae: Cochylina), John W. Brown
Insecta Mundi
Platphalonidia aenigmana Brown, new species (Lepidoptera: Tortricidae), is described and illustrated from Arizona, California, and Oregon, U. S. A. and Colombia, South America. The new species has been reared on numerous occasions from Garrya elliptica Dougl. ex Lindl. (Garryaceae) in northern California and Oregon, once on Arctostaphylos sp. (Ericaceae) in southern California, and once on Gomphrena globosa L. (Amaranthaceae) in Colombia. Various hypotheses are explored to explain the unusual disjunct geographic distribution of the species. In addition, Phalonidia bassii Razowski (Tortricidae) is transferred to Saphenista Walsingham, resulting in Saphenista bassii (Razowski, 1999), new combination.
A New Species Of Cymatodera Gray (Coleoptera: Cleridae) From Central Arizona, Jacques Rifkind
A New Species Of Cymatodera Gray (Coleoptera: Cleridae) From Central Arizona, Jacques Rifkind
Insecta Mundi
Cymatodera campbelli, new species (Coleoptera: Cleridae), is described from central Arizona, United States. Though superficially similar to several other small species of Southwestern Cymatodera Gray that are commonly collected at lights, this apparently rare species has distinctive coloration and surface sculpturing. Its discovery suggests that systematic collecting even in areas that have historically attracted entomological attention may still yield additions to our fauna.

A thermoregulatory decline occurs with age due to changes in muscle mass, vasoconstriction, and metabolism that lowers core body temperature (Tc). Although lower Tc is a biomarker of successful aging, we have previously shown this worsens cognitive performance in the APP/PS1 mouse model of Alzheimer's disease (AD). We hypothesized that elevating Tc with thermotherapy would improve metabolism and cognition in APP/PS1 mice. From 6-12 months of age, male and female APP/PS1 and C57BL/6 mice were chronically housed at 23 or 30°C. At 12 months of age, mice were assayed for insulin sensitivity, glucose tolerance, and spatial cognition. Plasma, hippocampal, and …

Photosystem I (PS I) is a light-driven oxidoreductase responsible for converting photons into chemical bond energy. Its application for renewable energy was revolutionized by the creation of the MenB deletion (ΔmenB) variant in the cyanobacterium Synechocystis sp. PCC 6803, in which phylloquinone is replaced by plastoquinone-9 with a low binding affinity. This permits its exchange with exogenous quinones covalently coupled to dihydrogen catalysts that bind with high affinity, thereby converting PS I into a stable solar fuel catalyst. Here, we reveal the 2.03-Å-resolution cryo-EM structure of a recent MenB variant of PS I. The quinones and their binding environment are …

This study is dedicated to the economic valuation of human capital (HC) in the regions where the Indigenous peoples of Kamchatka reside. The entire Kamchatksky Krai is considered an Indigenous people’s ancestral territory. However, in this study, only municipalities whose population is more than one-third Indigenous were chosen for the assessment. This includes six municipal districts and one urban district (Aleytsky, Bystrinsky, Karaginsky, Olyutorsky, Penzhinsky, and Tigilsky municipal districts and Palana urban district). The study employs statistical analysis and integrated, situational approaches: the investment approach was deemed the most appropriate tool for the economic assessment of HC in Indigenous territories. …
An Assessment Of The Impact Of Fentanyl On Post-Mortem Interval From A Decomposition And Biochemical Perspective, Kaylene Mcdonald
An Assessment Of The Impact Of Fentanyl On Post-Mortem Interval From A Decomposition And Biochemical Perspective, Kaylene Mcdonald
Senior Honors Theses
In the realm of body decomposition, bodies undergo a plethora of different metabolic and chemical changes. The human body follows a very consistent pattern and predictable time frame, with the exclusion of extenuating circumstances. The presence of fentanyl at the time of death provides the possibility of changes in decomposition rates, potentially skewing the time of death estimations. This research analyzes the varying decompositional stages of a body and their subsequent close relations with activity in the environment around it, specifically investigating the impacts of fentanyl on those surroundings and postmortem interval estimation determinations. This research found evidence that fentanyl …

Akt Kinases As Therapeutic Targets, Dalal Hassan, Craig Menges, Joseph Testa, Alfonso Bellacosa
Student Papers, Posters & Projects
AKT, or protein kinase B, is a central node of the PI3K signaling pathway that is pivotal for a range of normal cellular physiologies that also underlie several pathological conditions, including inflammatory and autoimmune diseases, overgrowth syndromes, and neoplastic transformation. These pathologies, notably cancer, arise if either the activity of AKT or its positive or negative upstream or downstream regulators or effectors goes unchecked, superimposed on by its intersection with a slew of other pathways. Targeting the PI3K/AKT pathway is, therefore, a prudent countermeasure. AKT inhibitors have been tested in many clinical trials, primarily in combination with other drugs. While …

To better understand linkages between hydrology and ecosystem carbon flux in northern aquatic ecosystems, we evaluated the relationship between plant communities, biofilm development, and carbon dioxide (CO) exchange following long-term changes in hydrology in an Alaskan fen. We quantified seasonal variation in biofilm composition and CO exchange in response to lowered and raised water table position (relative to a control) during years with varying levels of background dissolved organic carbon (DOC). We then used nutrient-diffusing substrates (NDS) to evaluate cause-effect relationships between changes in plant subsidies (i.e., leachates) and biofilm composition among water table treatments. We found that background DOC …

Introduction: B-cell acute lymphoblastic leukemia (B-ALL) in adults often presents a poor prognosis. ID1 and ID3 genes have been identified as predictors of poor response in Colombian adult B-ALL patients, contributing to cancer development. In various cancer models, these genes have been associated with immune regulatory populations within the tumor immune microenvironment (TIME). B-ALL progression alters immune cell composition and the bone marrow (BM) microenvironment, impacting disease progression and therapy response. This study investigates the relationship between ID1 and ID3 expression, TIME dynamics, and immune evasion mechanisms in adult B-ALL patients. Methods: This exploratory study analysed BM samples from 10 …

Down-regulation of BCL11A protein reverses the fetal (HbF, α2γ2) to adult (HbA, α2β2) hemoglobin switch and is exploited in gene-based therapy for hemoglobin disorders. Due to reliance on ex vivo cell manipulation and marrow transplant, such therapies cannot lessen disease burden. To develop novel small molecule approaches, we interrogated the state of BCL11A protein in erythroid cells. We report that tetramer formation mediated by a single zinc-finger (ZnF0) is required for production of steady-state protein. Beyond its role in protein stability, the tetramer state is necessary for γ-globin gene repression, as an engineered monomer fails to engage a critical corepressor …
