Virtual DriveThrus: Is OnlyFans the McDonald's of the Sex Industry?

Evolution of technology has allowed for various industries to adapt to an online platform, including education, retail, and even medicine. With this shift to an online realm, society has grown to expect efficiency and predictability from these industries, exemplified by reduced delivery times, increased accessibility to various products and resources, all while conducting this business from the comfort of the consumers own home. Sex work is no stranger to this shift to the online realm with the rise of websites for purchasing and viewing of porn, camming, erotica, etc. Similar to the ease of consumers, online platforms further provide ease for creators or sellers. This research aims to apply Ritzers concept of McDonaldization to the process of sex work on OnlyFans to determine how predictability, efficiency, control, and calculability have made it easier and safer for sex workers to conduct their work online while simultaneously increasing their profits.

Exploring the idea of “land back” as the answer to achieving sustainable self-determination

The right to Indigenous self-determination is a right that is inherent in all Indigenous communities and it is a right that is undeniable. Nonetheless, with the advent of colonization came a marginalization of Indigenous peoples in Canada and their systems of self-governance and self-determination, limiting the possibilities of practicing these systems of governance and economies in today’s society. As such, the contemporary reality facing Indigenous peoples in Canada today is that what governance structures and models they do have are grounded largely on the principles of global capitalism¬– one driven by values that both contradict Indigenous cultures and traditional values and actively seeks to erode them. My paper aims to explore the idea of sustainable self-determination and the concept of true reconciliation using the “land back” argument which provides a real opportunity for the implementation of sustainable Indigenous self-determination when analysed against the framework of consent-based jurisdiction and Indigenous reclamation.

Integrate me one more time: ERVK integrase as a source of DNA damage in neurodegenrative disease

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease impacting brain and spinal cord motor neurons. Endogenous retroviruses are ancient viral elements in the human genome. Endogenous retrovirus-K (ERVK) integrase enzyme is expressed in affected ALS tissues. Integrase inserts viral DNA into the host genome by breaking host DNA and relying on cellular repair mechanisms to fix this damage. Failure to repair DNA damage can lead to necroptotic cell death and neurodegeneration. To study ERVK integrase-mediated DNA damage and necroptosis, I will insert ERVK integrase expression vectors into a variety of cell types, including stem cells for the generation of cerebral organoids. I will use Western blot and confocal imaging to identify the presence of ERVK integrase, DNA damage (γH2AX), engagement of DNA damage repair pathways (BRCA1, DNAPK, and PARP1), and ultimately necroptosis (p-MLKL). Understanding cellular effects of ERVK integrase-driven neurodegeneration may lead to future therapeutics for patients with ALS.

ERVK Intergrase Block Antiviral Immunity

Endogenous retrovirus-K (ERVK) is a group of retroviral elements in the human genome that are upregulated in the brains and spinal cords of patients with Amyotrophic lateral sclerosis (ALS), a neurodegenerative disease without a cure. A hallmark of ALS pathology includes DNA damage, a phenomenon known to be initiated by retroviral integrases (INs). Thus, I am investigating the role of the ERVK IN enzyme in ALS. My research shows that ERVK IN causes DNA damage and prevents antiviral IRF3 activity in astrocyte brain cells. I am further investigating how the cellular pathway leading to IRF3 activation is disrupted by ERVK IN. Lastly, I am repeating these experiments with the addition of integrase inhibitors to determine if ERVK IN-mediated cellular effects are reversed. As ERVK is known to be active in ALS, this gives hope that IN inhibitors can be repurposed as an effective treatment option.

A Simple Test To Increase Treatment Response of Breast Cancer

Tamoxifen is a very effective form of endocrine therapy for the treatment of Estrogen Receptor positive (ER+) breast cancers. However, approximately 50% of all patients develop a resistance to the drug. There are reports suggesting involvement of the PI3K/mTOR pathway in endocrine resistance and that N-myristoyltransferase (NMT) phosphorylation by mTOR may play a role. The overreaching goal of my research is to determine the potential role of NMT in endocrine therapy resistance development and to determine if NMT subcellular expression patterns can be used as a predictive biomarker. Several putative phosphorylation sites in NMT have been identified and mutated to alanine (phospho dead) or glutamic acid (phospho mimic). Various NMT mutants along with wild type (wt) NMT plasmids were prepared and expressed in ER+ breast cancer cells. Future studies are directed towards treating these cells with tamoxifen to investigate whether NMT phosphorylation by mTOR confers resistance to endocrine therapy.

Fostering a Safe Space for Dialogue between Indigenous and Newcomer Communities

Winnipeg is experiencing an interesting period: it has a large Indigenous population, and an increasing newcomer population. The two communities – as diverse as they are – share a lot in common: a history of colonial encounter, socioeconomic challenges, and communal values. There is however, very little interaction between the two communities. This absence of interaction is due to a lack of knowledge, understanding and awareness about each other. As a result, this has pitted the two communities against each other. Hence, there is a need to create a safe space for dialogue. Community organizations (in the settlement sector) have a responsibility to institutionalize dialogue. It is of prime importance that newcomers understand the colonial history of Canada and some of its contemporary legacies, as well as basic awareness on the First peoples of this land. This is the essence of Truth and Reconciliation calls to action #93.

Improving the Prognosis and Diagnosis of Chronic Kidney Disease Using Naive Bayes Algorithm

Big data represents a ground-breaking opportunity for healthcare industry to improve service quality. Clinical Decision Support will help the clinician answer clinical questions quickly when information is needed, especially if the learning method is built into the Electronic Health Record (EHR). This paper delineates how unstructured data can be mined from different point of care devices to improve the prognosis and diagnosis of Chronic Kidney Disease (CKD). This proposed mining system will scrape and analyze data from ubiquitous point of care devices and make predictions. This system will help predict potential events which may be symptoms of Kidney disease or a drug interaction that could lead to kidney problems. CKD is among the top ten leading causes of death in Canada according to Statistics Canada. This research will help clinicians in the areas of chronic disease management, prenatal patients monitoring, preventative medicine, and aggregation of medical information.

Silent No More: Augmented IFNy signaling re-activates Human Endogenous Retrovirus-K

Retroviral-derived sequences called human endogenous retroviruses (ERVs) comprise a large proportion of the human DNA. Re-activation of the youngest endogenous retrovirus, ERVK, has been implicated in the neuropathology of Amyotrophic Lateral Sclerosis (ALS). Unfortunately, the signals that re-activate ERVK remain unclear. ALS is marked by augmented levels of the pro-inflammatory cytokine Interferon-γ (IFNγ), which is a potent activator of HIV – another retrovirus. Using real-time polymerase chain reaction and western blot, we show for the first time that IFNγ enhances ERVK gene transcription, polyprotein expression, and promotes cleavage of the polyprotein into reverse transcriptase (RT) subunits in human astrocytic and neuronal cell lines. This coincides with an increase in cellular RT enzymatic activity. Fluorescent imaging further reveals markedly enhanced cytoplasmic, perinuclear, and nuclear RT staining in IFNγ stimulated cells. These newly established in vitro models of ERVK re-activation will permit further examination of ERVK biology in the context of neuroinflammatory disease.

In Silico modeling of the endogenous retrovirus K protease

The human genome is filled with ancient retrovirus-like elements called Human Endogenous Retroviruses. Most of these elements are inactive under normal conditions, but some endogenous retrovirus K family members are activated in inflammatory diseases. These genetic elements express classical retroviral proteins: polymerase, capsid and envelope proteins, as well as protease. Protease is essential for the maturation of structural viral proteins. Inhibition of ERVK protease may lead to amelioration of disease outcomes, as it does in Human Immunodeficiency Virus (HIV) infection. ERVK protease is poorly inhibited by drugs that target HIV protease; the discovery of new inhibitors is hampered by the lack of a published ERVK protease structure. An alignment of characterized retroviral proteases and prototypic ERVK proteases created using Geneious software was used to evaluate the suitability of ERVK protease for homology modeling. ERVK protease models will be used to predict in silico the efficacy of novel small molecule inhibitors.
