Mr Perfusion Imaging, Techniques And Role In Differentiating Radiation Necrosis And Tumor Recurrence, Raima Zakaria, Fatima Mubarak, Muhammad Shahzad Shamim

Department of Radiology

High grade brain tumours are treated with surgery, chemotherapy and radiation therapy and despite such aggressive treatment, can recur in a short span of time. MRI scan has been the conventional diagnostic modality to diagnose recurrence, although at times it becomes difficult for the neuroradiologists to differentiate between tumour recurrence and radiation necrosis. Herein lies the emergent need to explore the efficacy of functional imaging to assist in this diagnostic challenge. Recent studies have sought to do so with promising implications, which we have attempted to summarize in this review.

Hiring Algorithms In The Canadian Private Sector: Examining The Promise Of Greater Workplace Equality, Connor Bildfell

Canadian Journal of Law and Technology

Private-sector employers are increasingly using hiring algorithms as a tool for screening job applicants, comparing qualifications, and ultimately determining which candidates should be selected. Within this context, hiring algorithms make no small promise: a hiring process that is not only more efficient and effective, but also more supportive of workplace equality. This promise rests largely on the notion that traditional human-driven models of hiring are beset by subjective biases and prejudices, whereas hiring algorithms, which are driven by hard data and objective evidence, can eliminate certain human biases and prejudices, thereby promoting workplace equality. But can hiring algorithms deliver on …

Thermococcus Thioreducens' Inorganic Pyrophosphatase Purification, Christopher Nozum, Zeina Sleiman

Perpetua: The Journal of Undergraduate Research at UAH

Protein purification requires an intensive multi-step process that is customized to every protein’s characteristic for optimal results. In this study, we looked at the purification process of Inorganic Pyrophosphatase (IPPase), an essential protein found in all living organisms. The commonality of the protein does not veil the fact that the mechanism by which IPPase is hydrolyzed into two orthophosphates is not fully understood. To comprehend the mechanism, recombinant mutants of the conservative region in IPPase were expressed. However, to observe a possible change in structure of the recombinant mutants with crystallization, pure concentrated protein is needed. Therefore, protein purification is …

A Novel Model To Identify Factors Associated With Mobility Apprehension, Maggi R. Welch

Perpetua: The Journal of Undergraduate Research at UAH

The prevalence of limb loss in the United States is estimated at 1.9 million instances with approximately 185,000 amputations occurring annually. Studies report that after lower-limb amputation, patients have high levels of pain, leading to restrictions in functional activity, and are at risk for developing avoidance behaviors. Potential contributing factors include muscle weakness leading to balance and gait abnormalities, which perpetuates low mobility and mobility apprehension. The aim of the study was to determine factors associated with mobility apprehension in individuals who underwent surgery for a lower-limb amputation. Adult participants who had a well-fitting prosthesis and had the ability to …

Identifying Exosomes In Oral Squamous Cell Carcinoma With Efirm, Bram Holladay

Student Scholarship

Oral Squamous Cell Carcinoma (OSCC) affects 53,000 Americans each year making it the sixth most common cancer in the United States. The incidence rate may be even higher since current screening methods are underutilized and physical examinations can misdiagnose malignant oral tumors as benign inflammatory lesions. Recent advances in genetic, protein, and extracellular vesicle biomarker detection techniques can monitor the transformation of healthy cells into tumors before terminal stages arise. Biomarkers can be easily extracted from biofluids such as saliva making them less invasive than traditional tissue biopsies. One biomarker prevalent in OSCC is exosomes, which are extracellular vesicles that …

From Decarceration To E-Carceration, Chaz Arnett

Cardozo Law Review

Each year, millions of Americans experience criminal justice surveillance through electronic ankle monitors. These devices have fundamentally altered our understanding of incarceration, punishment, and the extent of the carceral state, as they are increasingly offered as moderate penal sanctions and viable solutions to the problem of mass incarceration. They purportedly enable decarceration, albeit with enhanced surveillance in the community as the compromise. Proponents of the devices tout the public safety and cost benefits while stressing the importance of depopulating prisons and returning individuals to theircommunities. In recent years, an oppositional movement has developed, focused on highlighting the social harms of …

Variability In Pcb Exposure Of Adolescent Sexual Maturation In Published Articles, Harshal Shet

Anthropology

One of the most important aspects of science is replication of research studies between different labs. This capability for scientists to check their work, and that of other scientists, leads to research results of interest being well-accepted and qualified. When research studies cannot be replicated under ideal experimental conditions, people can believe results that are not consistent, and the data is not real. The main objective of this study was to examine the variability on the levels of different PCB congeners from various studies and their effects on sexual maturation in adolescent population. The detectable levels of different PCB congeners …

Hippocampal Extracellular Potassium Levels And Formation Of Spatial Memory In Response To Retrodialysis Insulin Administration, Gabrielle Shames

Anthropology

Insulin is the most common treatment for hyperglycemia, such as that caused by type 1 or type 2 diabetes mellitus. Insulin causes cellular uptake and storage of glucose to maintain homeostasis and also plays important roles in other systems; an important example is regulation of potassium. In the periphery, insulin administration has been shown to increase the cellular uptake of potassium via Na+/K+ ATPase, leading to hypokalemia. Research in our lab and others has shown that insulin is a key regulator of cognitive function and local metabolism within the hippocampus. To date, however, no studies have examined whether insulin acts …

The Myth Of The "Gray Area" In Rape: Fabricating Ambiguity And Deniability, Maddie Brockbank

Dignity: A Journal of Analysis of Exploitation and Violence

Sexual violence is a pervasive issue identified on post-secondary campuses. Existing research focuses almost exclusively on an American context and quantitatively explores the frequency with which sexual assault occurs on campuses. As men are overrepresented as perpetrators, it is necessary to investigate their perspectives on the issue. The present study qualitatively examines the perspectives of white, heterosexual, male students to facilitate dialogue about sexual violence on university campuses in Ontario. Several themes emerged, specifically pertaining to negotiations of consent, a perceived “grey area,” peer influence, and how the social construction of masculinity fosters specific beliefs that excuse sexually violent beliefs, …
