Descriptive Report On Dietary Remains From Aztec And Salmon Ruins Coprolites, Karl J. Reinhard

Karl Reinhard Publications

This report focuses only on dietary results from the Aztec Ruins and Salmon Ruins coprolites. The parasitological analysis was completed in 2018 and was the focus of several papers that were summarized by Camacho and Reinhard (2020). This did not include DNA analysis. The coprolites from these sites are not appropriate sources of DNA testing.

The main conclusion of the analysis are:

1) Two very distinct plant spectra are represented in Aztec Ruins West (ARW) room 219 and room 225.

2) The three contexts of ARW room 219 show interesting variation in food selection, however these are small samples.

3) …


Evaluating The Role Of Glucocorticoids On The Host Response To Helicobacter Pylori Infection, Sara Druffner 2024 West Virginia State University

Evaluating The Role Of Glucocorticoids On The Host Response To Helicobacter Pylori Infection, Sara Druffner

Graduate Theses, Dissertations, and Problem Reports (ETD)

Gastric cancer is the fifth most common cancer and the fifth leading cause of cancer deaths worldwide. Helicobacter pylori infection is the number one risk factor for gastric cancer development. Roughly 50% of the world’s population is infected with H. pylori, though only 1-3% of those infected will develop cancer. H. pylori drives chronic inflammation that creates the requisite environment for carcinogenesis, yet it remains unclear why some individuals develop cancer and others do not. Most mechanistic studies are done in mice, however H. pylori is not a natural mouse pathogen. Research is typically done either with mouse-adapted strains of …


Epitope Mapping Novel Monoclonal Antibodies Against Borrelia Burgdorferi Surface Proteins Ospc And Bmpa, Eliza M. Doyle 2024 University of Central Florida

Epitope Mapping Novel Monoclonal Antibodies Against Borrelia Burgdorferi Surface Proteins Ospc And Bmpa, Eliza M. Doyle

Honors Undergraduate Theses

In response to the progressive nature of Lyme disease, direct diagnostic testing of Borrelia burgdorferi surface proteins was proposed as a quicker and more sensitive alternative to the current indirect detection methods. To determine the ability of novel monoclonal antibodies to detect the surface lipoproteins BmpA and OspC, recombinant fragments of these proteins were created. These fragments were tested against the putative diagnostic antibodies via western blotting as a means to map the epitope of each of the proteins that the respective antibodies recognize. All BmpA fragments with deletions on the N-terminal end exhibited reactivity, indicating that the epitope is …

Rift Valley fever virus (RVFV) is a negative-sense virus that was first described in 1930 when it was isolated from sheep during an outbreak. In the last 25 years there has been a spread in the geographical range into the Middle East. The most susceptible animals are cattle, goats, sheep, and camels. The most overt symptom of livestock infection is that infected pregnant animals experience spontaneous abortion. Humans are susceptible as well and symptoms range from mild febrile illness to liver necrosis, blindness, hemorrhagic fever, and death. An important player in the cellular innate response to RVFV infections is the …

Sle1 and Faslpr are two lupus susceptibility loci that lead to manifestations of systemic lupus erythematosus. To evaluate the dosage effects of Faslpr in determining cellular and serological phenotypes associated with lupus, we developed a new C57BL/6 (B6) congenic lupus strain, B6.Sle1/Sle1.Faslpr/+ (Sle1homo.lprhet) and compared it with B6.Faslpr/lpr (lprhomo), B6.Sle1/Sle1 (Sle1homo), and B6.Sle1/Sle1.Faslpr/lpr (Sle1homo.lprhomo) strains. Whereas Sle1homo.lprhomo mice exhibited profound lymphoproliferation and early mortality, Sle1homo.lprhet mice had a lifespan comparable to B6 mice, with no evidence of splenomegaly or lymphadenopathy. Compared to B6 monogenic lupus strains, Sle1homo.lprhet mice exhibited significantly …

The use of PD-1 immune checkpoint inhibitor medications has become a common practice in the treatment of recurrent and metastatic head and neck squamous-cell carcinomas. Success in this setting has led to the investigation of their efficacy in locally advanced cases as a part of first-line therapy. In this report, we detail the treatment response to palliative intent immunotherapy of three geriatric patients with mandibular gingival squamous-cell carcinoma who decided against surgical intervention. Patient #1 was treated with pembrolizumab, a PD-1 inhibitor, and displayed complete clinical and radiologic response of the gingival mass after three months of treatment, which is …


Role Of The Anti-Viral Immune Response In Neural Cell Modulation And Neurological Sequelae Of Childhood Viral Infections, Yashika Kamte 2023 Duquesne University

Role Of The Anti-Viral Immune Response In Neural Cell Modulation And Neurological Sequelae Of Childhood Viral Infections, Yashika Kamte

Electronic Theses and Dissertations

Viral infections of the central nervous system (CNS) often result in neurological sequelae and are considered a risk factor for the development of neurological disease. Moreover, the outcomes of a viral infection are largely dependent on the age of the host, with younger hosts developing more profound neuropathology. Perhaps the developing brain coupled with an immature immune system contributes to worse outcomes in the very young. Children suffering from brain infections are more prone to develop enduring neurological impairments even after recovery from the infection. Although majority of the brain growth occurs in utero, neurodevelopment continues throughout the juvenile …

Towards A Mode Of Action For The Anti-Schistosomal Aryl Hydantoins, Thomas Schulze

Theses & Dissertations

Schistosomiasis is a significant human disease caused by the helminth parasite Schistosoma mansoni. Praziquantel remains the only clinically used treatment, yet it is rapidly metabolized and only effective against the adult stage worm infection. Ro 13-3978 (AR02) is a potent antischistosomal compound with activity against multiple S. mansoni life stages; however, it manifests anti-androgenic activity. Additionally, the mechanism of action for worm clearance remains unknown. The structure of Ro 13-3979 was used to generate optimized derivatives, including AR102, that show increased potency towards worms, reduced off-target anti-androgen effects, and extended half-life thereby increasing the feasibility for a single-dose curative treatment. …

Understanding The Effect Of Chikungunya Virus Infection On Bone Homeostasis, Enakshi Roy

Theses & Dissertations

Chikungunya virus (CHIKV) is a mosquito-borne virus that causes Chikungunya fever (CHIKF), characterized by high fever, headache, rash, and joint pain. With global travel on the rise, infections caused by CHIKV have emerged in new regions, expanding their geographic range and infecting susceptible hosts. Currently, no approved prophylactic or therapeutic measures exist to prevent or treat these infections, with prevention strategies primarily focused on vector control. However, these measures have proven inadequate due to the emergence of mutations that enhance viral transmission or vector range. Therefore, urgent attention is needed to develop therapies to treat the infection. Although CHIKV has …

Role Of Gonadotropin-Releasing Hormone 2 And Its Receptor In Human Reproductive Cancers, Dr. Amy T. Desaulniers, Brett White

School of Veterinary and Biomedical Sciences: Faculty Publications

Gonadotropin-releasing hormone (GnRH1) and its receptor (GnRHR1) drive reproduction by regulating gonadotropins. Another form, GnRH2, and its receptor (GnRHR2), also exist in mammals. In humans, GnRH2 and GnRHR2 genes are present, but coding errors in the GnRHR2 gene are predicted to hinder full-length protein production. Nonetheless, mounting evidence supports the presence of a functional GnRHR2 in humans. GnRH2 and its receptor have been identified throughout the body, including peripheral reproductive tissues like the ovary, uterus, breast, and prostate. In addition, GnRH2 and its receptor have been detected in a wide number of reproductive cancer cells in humans. Notably, GnRH2 analogues …

Bacterial vaginosis (BV), a dysbiosis of the vaginal microbiota, is a common coinfection with Chlamydia trachomatis (Ct), and BV-associated bacteria (BVAB) and their products have been implicated in aiding Ct evade natural immunity. Here, we determined if a non-optimal vaginal microbiota was associated with a higher genital Ct burden and if metronidazole, a standard treatment for BV, would reduce Ct burden or aid in natural clearance of Ct infection. Cervicovaginal samples were collected from women at enrollment and, if testing positive for Ct infection, at a follow-up visit approximately one week later. Cervical Ct burden was assessed by inclusion forming …
