Characterization of 18kDa Mitochondrial Translocator Protein in Relation to Neuropathological Elements of Neurodegenerative Diseases

Description
Neuroinflammation is mediated by activated microglia, the chief immune response of the central nervous system. Mitochondrial 18kDa translocator protein (TSPO) is upregulated in activated microglia and has been used in PET scans to analyze peripheral and central inflammation with TSPO radioligand [18F]DPA-714.

Neuroinflammation is mediated by activated microglia, the chief immune response of the central nervous system. Mitochondrial 18kDa translocator protein (TSPO) is upregulated in activated microglia and has been used in PET scans to analyze peripheral and central inflammation with TSPO radioligand [18F]DPA-714. To test the hypothesis that TSPO is involved in microglial mediation of inflammatory responses to Aβ and other Alzheimer’s pathological elements, TSPO expression was evaluated in relation to microglia specific markers (IBA1 and LN3 antibodies) and markers for AD pathology, Aβ (6E10 antibody) and hyperphosphorylated tau (AT8 antibody). To test that TSPO is involved in inflammatory pathways, HEK cells transfected with TSPO plasmids were assessed for oxidative stress in response to Alzheimer’s disease pathogenic agents, β Amyloid (Aβ), and Parkinson’s disease α-synuclein (α-syn).

Fluorescence microscopy of TSPO transfected HEK cell cultures labeled with Carboxy-H2DCFDA and treated with Beta Amyloid (Aβ) and α-synuclein (α-syn) resulted in DAPI fluorescing Human Embryonic Kidney (HEK) nuclei in blue and Green Fluorescent Protein (GFP) fluorescing reactive oxygen species (ROS) or oxidative stress in cell cytoplasm in green. Preliminary study suggests TSPO transfected cells may be used to test oxidative stress with disease pathological elements (Aβ and α-synuclein). In IHC, TSPO immunoreactivity was observed in IBA1 and LN3 marked microglia with varying degrees of expression. Beaded structures were also observed with TSPO immunoreactivities, possibly representing microglia processes. TSPO immunoreactivity was observed in and surrounding amyloid plaques and p-tau immunoreactive neurites. This demonstrates that TSPO is predominantly expressed in microglia and are closely associated with Alzheimer’s disease pathological elements, suggesting involvement of TSPO-expressing microglia in neurodegenerative processes.

Describing Virus Vaccines and Controversies: Comparison of Three Vaccines in Medical and Social Contexts

In the United States, a dispute has arisen over the safety and need for vaccination, particularly in regard to compulsory vaccination laws. New outlets and social media sites publish countless reports about the dangers of vaccines or of known adverse reactions as well as imagined or unproven worries. Individuals' rights to choose to get vaccinated or allow their children to be vaccinated comes to direct conflict with measures needed to protect communities from preventable viral diseases. The controversy surrounding vaccines is not new, nor necessarily are the fundamental reasons for skepticism. Looking back through the history of vaccines as a medical tool, the evolution of the controversy can be observed taking place with each new historical context, scientific development, and social conditions. Despite scientific research and assurances of vaccine safety, opposition and unease about vaccination appear to take Looking individually at the development and distribution of the smallpox (variola virus), polio (poliovirus) and human papilloma virus(HPV) vaccines, concerns regarding the violation of personal rights, safety of vaccines themselves, and social stigmas and connotations surrounding vaccines can be seen to evolve and change. Due to the way doubt can manifest in different ways over time, it may be impossible to fully end the vaccine debate. However, nderstanding the sociological factors behind anti-vaccine sentiment may allow healthcare professionals to work with concerned people with a particular care to address these visceral and sometimes irrational fears surrounding vaccination.

Student to Student: A Guide to Anatomy is an anatomy guide written by students, for students. Its focus is on teaching the anatomy of the heart, lungs, nose, ears and throat in a manner that isn't overpowering or stress inducing. Daniel and I have taken numerous anatomy courses, and fully comprehend what it takes to have success in these classes. We found that the anatomy books recommended for these courses are often completely overwhelming, offering way more information than what is needed. This renders them near useless for a college student who just wants to learn the essentials. Why would a student even pick it up if they can't find what they need to learn? With that in mind, our goal was to create a comprehensive, easy to understand, and easy to follow guide to the heart, lungs and ENT (ear nose throat). We know what information is vital for test day, and wanted to highlight these key concepts and ideas in our guide. Spending just 60 to 90 minutes studying our guide should help any student with their studying needs. Whether the student has medical school aspirations, or if they simply just want to pass the class, our guide is there for them. We aren't experts, but we know what strategies and methods can help even the most confused students learn. Our guide can also be used as an introductory resource to our respective majors (Daniel-Biology, Charles-Speech and Hearing) for students who are undecided on what they want to do. In the future Daniel and I would like to see more students creating similar guides, and adding onto the "Student to Student' title with their own works... After all, who better to teach students than the students who know what it takes?

Arizona State University and Banner Thunderbird Hospital have partnered to provide pre-med students with an internship at a local emergency department. Students entering into this program will have access to each patient's vital signs, medical imaging, lab tests, and medications. This access presents students with an opportunity to learn about a variety of tools used in the assessment and treatment of emergency room patients. In order to enhance the amount of knowledge students take away from the program, I created a handbook summarizing a variety of diagnostic tests and medications. The first section of the handbook (assessment) is spilt up into the three following categories: vital signs, medical imaging, and lab tests. The second section (treatment) consists of one category, medications. Each section was written with emphasis on basic physiology, and is intended to provide pre-med students with a foundation for building further medical knowledge. Although this handbook was tailored to the information students are most likely to encounter working in Banner Thunderbird Hospital's emergency department, it is still appropriate for any student interested in learning about emergency medicine.

This meta-study analyzes the shift in research literature that focuses on the various shared causes of type 2 diabetes and Alzheimer’s disease from the years 2000 to 2022. Examining literature trends over the past two decades can offer valuable insight into the evolving emphasis on various topics. Altogether, a total of 154 publications were collected from the Pubmed and ResearchGate databases using a non-biased protocol and methodology. Each paper was then categorized by the topics it discussed. Visual representation of the data such as bar graphs and tables were created to comprehend the trends presented in the group of papers. The collection of publications were then differentiated into years of early (prior to 2005 or 2010) and late (after 2006 or 2011) periods to perform a statistical analysis of the patterns in the timeline. The increase in publications discussing Alzheimer’s disease, amyloid beta deposition, gut microbiota, mitochondrial dysfunction, type 2 diabetes, and tau hyperphosphorylation from the early to the late period were statistically significant. This means that the increase was not due to random chance, but rather supported by evidence. This can be attributed to researchers and physicians discovering more evidence that establishes a link between specific factors, type 2 diabetes, and Alzheimer’s disease. This reflects a genuine acknowledgment of the importance of understanding and addressing the relationship between these two pathologies. Research in the trends of literature can provide information in which areas of research are the most studied or understudied. Based on these findings, the identification of areas with limited knowledge and potential research directions can be inferred, ultimately leading to the enhancement of preventive measures and therapeutic approaches for these conditions.
