Synthesis And Characterization Of Medicinally Privileged Aza Heterocycles, Nneoma James Aug 2024

Synthesis And Characterization Of Medicinally Privileged Aza Heterocycles, Nneoma James

Theses and Dissertations

Four-membered cyclic amides, commonly known as β-lactams, have played a crucial role in drug discovery research since its discovery by Alexander Fleming in 1928 from Penicillium notatum. The β-lactam antibiotics are broadly effective against several bacterial infections through acylating the transpeptidase involved in cross-linking peptides to form peptidoglycan or periplasmic murein, which is a fundamental constituent of the bacterial cell wall for both the gram-positive (ten or more layers) and gram-negative (one or two layers) bacteria. Although for more than eight decades, β-lactams have been recognized as antibiotics, later, other medicinal activities of β-lactam derivatives have been reported, including lowering …


Co-Localization Of Osteoclasts Differentiation Markers In An Implant Model In Diabetic Mice, Diego Adobbati, Deborah Rocha Seixas, Danieli Rodrigues, Claudia C. Biguetti Jul 2024

Co-Localization Of Osteoclasts Differentiation Markers In An Implant Model In Diabetic Mice, Diego Adobbati, Deborah Rocha Seixas, Danieli Rodrigues, Claudia C. Biguetti

School of Podiatric Medicine - Student Research

Introduction and Hypothesis: Diabetes can impair implant osseointegration and impact implant functionality. While significant research has focused on osteogenesis during the osseointegration, little attention has been given to pre-osteoclast differentiation. We hypothesize that diabetes increases pre-osteoclast activity potentially leading to implant failure. This study aims to identify and localize osteoclast markers, specifically DC-STAMP (Dendritic Cell-Specific Transmembrane Protein) and NFATc2 (Nuclear Factor of Activated T-cells, cytoplasmic 2), in diabetic (D) and non-diabetic (ND) mice.

Methodology: Twenty-four 16-week-old male 129 Sv mice (12 diabetic and 12 non-diabetic) underwent implantation with a 0.5x1.5 mm commercially pure titanium screw in the right maxillary bone. …

Recent research suggests that infection with Onchocerca volvulus induces neurocognitive decline. This study sought to compare the cognitive outcomes of elderly persons based on onchocerciasis infection status and report the overall prevalence of dementia in the rural Ntui Health District in Cameroon. A community-based approach was used to recruit 103 participants aged ≥60 years. Dementia screening was done using the Community Screening Interview for Dementia (CSID) tool with a cut-off value of ≤29.5. O. volvulus infection was determined via microscopic examination of skin snips and serological testing of Ov16 antibodies using rapid diagnostic tests. Overall, the prevalence of dementia was …


Readability And Suitability Of Local Disaster Preparedness Materials In Predominantly Hispanic Border Communities: A Case Study Of Cameron County, Texas, Katarzyna Sepielak, Dawid K. Wladyka Jul 2024

Readability And Suitability Of Local Disaster Preparedness Materials In Predominantly Hispanic Border Communities: A Case Study Of Cameron County, Texas, Katarzyna Sepielak, Dawid K. Wladyka

Sociology Faculty Publications

Community awareness is a key component of disaster resilience and numerous agencies developed a plethora of preparedness materials. Previous studies evaluated national-level resources and social media content indicating that these efforts are not effectively reaching vulnerable populations, as the information is provided at or above the secondary education level. However, the local-specific content has been mostly overlooked in the analyses, subsequently neglecting the needs of areas with specific demographics and hazards, like predominantly Hispanic border communities. Thus, this study turns to local preparedness and mitigation materials, rather than general internet searches or national level documents. We analyze information provided on …

Overuse of antimicrobials has greatly contributed to the increase in the emergence of multidrug-resistant bacteria, a situation that hinders the control and treatment of infectious diseases. This is the case with urinary tract infections (UTIs), which represent a substantial percentage of worldwide public health problems, thus the need to look for alternatives for their control and treatment. Previous studies have shown the usefulness of autologous bacterial lysates as an alternative for the treatment and control of UTIs. However, a limitation is the high cost of producing individual immunogens. At the same time, an important aspect of vaccines is their immunogenic …

Neutrophil To Lymphocyte Ratio (Nlr) In Captive Olive Baboons (Papio Anubis): The Effects Of Age, Sex, Rearing, Stress, And Pregnancy, Sarah J. Neal, Angela M. Achorn, Steven J. Schapiro, William D. Hopkins, Joe H. Simmons

Anthropology Faculty Publications

In apes and humans, neutrophil to lymphocyte ratio (NLR) can be used as a predictive indicator of a variety of clinical conditions, longevity, and physiological stress. In chimpanzees specifically, NLR systematically varies with age, rearing, sex, and premature death, indicating that NLR may be a useful diagnostic tool in assessing primate health. To date, just one very recent study has investigated NLR in old world monkeys and found lower NLR in males and nursery-reared individuals, as well as a negative relationship between NLR and disease outcomes. Given that baboons are increasingly used as research models, we aimed to characterize NLR …

Kalaria, Gladys Maestre, Simin Mahinrad, Daisy Acosta, Rufus Akinyemi, Suvarna Alladi, Ricardo F. Allegri, Faheem Arshad, David Oluwasayo Babalola, Noe Garza

School of Medicine Publications

Two of every three persons living with dementia reside in low- and middle-income countries (LMICs). The projected increase in global dementia rates is expected to affect LMICs disproportionately. However, the majority of global dementia care costs occur in high-income countries (HICs), with dementia research predominantly focusing on HICs. This imbalance necessitates LMIC-focused research to ensure that characterization of dementia accurately reflects the involvement and specificities of diverse populations. Development of effective preventive, diagnostic, and therapeutic approaches for dementia in LMICs requires targeted, personalized, and harmonized efforts. Our article represents timely discussions at the 2022 Symposium on Dementia and Brain Aging …


High All-Cause Mortality And Increasing Proportion Of Older Adults With Tuberculosis In Texas, 2008–2020, Belinda A. Medrano, Miryoung Lee, Gretchen L. Gemeinhardt, Lana Yamba, Blanca I. Restrepo May 2024

High All-Cause Mortality And Increasing Proportion Of Older Adults With Tuberculosis In Texas, 2008–2020, Belinda A. Medrano, Miryoung Lee, Gretchen L. Gemeinhardt, Lana Yamba, Blanca I. Restrepo

School of Medicine Publications

Pulmonary tuberculosis (PTB) elimination efforts must consider the global growth of the ageing population. Here we used TB surveillance data from Texas, United States (2008–2020; total n = 10656) to identify unique characteristics and outcomes in older adults (OA, ≥65 years) with PTB, compared to young adults (YA, 18–39 years) or middle-aged adults (40–64 years). We found that the proportion of OA with PTB increased from 15% in 2008 to 24% in 2020 (trend p < 0.05). Diabetes was highly prevalent in OA (32%) but not associated with adverse outcomes. Death was 13-fold higher in OA compared to YA and was 7% at the time of diagnosis which suggests diagnostic delays. However, once TB was suspected, we found no differences in culture, smear, or nucleic acid detection of mycobacteria (although less lung cavitations) in OA. During treatment, OA had less drug-resistant TB, few adverse reactions and adhered with TB treatment. We recommend training healthcare workers to ‘think TB’ in OA, for prompt treatment initiation to diminish deaths. Furthermore, OA should be added as a priority group to the latent TB treatment guidelines by the World Health Organization, to prevent TB disease in this highly vulnerable group.

Effect Of Short-Term Exposure To Pesticide Mixture On Tissue Architecture, Body Fluid Conditions, Nitrative Stress And Osmoregulation Of American Oyster, Crassostrea Virginica, Asif Ahmed

Theses and Dissertations

Pesticides are used widely to control weeds and pests in agricultural settings but harm non-target aquatic organisms. We examined the effect of short-term exposure (one week) to pesticide mixtures (low dose: 0.5 μg/L Roundup®, 0.5 μg/L 2,4-D, and 0.4 μg/L atrazine; high dose: 1 μg/L Roundup®, 1 μg/L 2,4-D, and 0.8 μg/L atrazine) on American oyster (Crassostrea virginica, an important shellfish and seafood species) under controlled laboratory conditions. Histological analyses demonstrated the atrophy in oysters' gills, digestive glands, and connective tissue. The protein concentrations and glucose levels dropped significantly in the high-dose treatment. The number of hemocytes in connective tissue …


Bayesian Estimation Of Reproduction Numbers From Distributions Of Outbreaks Sizes: Branching Process Approach, Alberta Araba Johnson May 2024

Bayesian Estimation Of Reproduction Numbers From Distributions Of Outbreaks Sizes: Branching Process Approach, Alberta Araba Johnson

Theses and Dissertations

The Generalized Poisson distribution is useful in modeling epidemiological processes as a branching stochastic processes problem. Our goal is to construct accurate and reliable estimators for the reproduction number (R0) (i.e., the number of secondary infections), particularly in the context of disease outbreaks modeled by a Galton-Watson process. Towards this goal, we construct the classical Bayes estimator, the Maximum Likelihood estimator, and the Empirical Bayes (EB) estimator under the Square Error Loss function in Chapter II. We prove that the Empirical Bayes estimator is asymptotically optimal and estimate the rate of convergence. We then proceed to monotonize the Empirical Bayes …

Dengvaxia is the first dengue vaccine recommended in the United States (U.S.). It is recommended for children aged 9–16 y with laboratory-confirmed previous dengue infection and living in areas where dengue is endemic. We conducted focus groups with parents and in-depth interviews with key informants (i.e. practicing pediatricians, physicians from immunization clinics, university researchers, and school officials) in Puerto Rico (P.R.) to examine acceptability, barriers, and motivators to vaccinate with Dengvaxia. We also carried out informal meetings and semi-structured interviews to evaluate key messages and educational materials with pediatricians and parents. Barriers to vaccination included lack of information, distrust toward …

The Role Of A Cancer Testis-Antigen In Regulating Tumor Growth And Oncogenic Pathways In Triple-Negative Breast Cancer., Melina J. Sedano, Alana L. Harrison, Victoria Reid, Subramanian Dhandayuthapani, Shrikanth S. Gadad

Research Symposium

Breast cancer is the second leading cause of cancer-related deaths in women, after lung cancer. Unfortunately, it is the primary cause of death among Hispanic women. Approximately 10-20% of breast cancers are classified as basal (triple-negative) subtypes, which are challenging to treat due to the absence of specific targets. Triple-negative breast cancer is a highly aggressive and lethal type of tumor, particularly among Hispanic women, with a poor prognosis compared to other breast cancer subtypes. Therefore, it is crucial to identify new molecules with therapeutic and prognostic values to treat this evolving disease. Multiple studies have demonstrated that X-linked genes …

Mechanical Engineering Faculty Publications

A well-ventilated room is essential to reduce the risk of airborne transmission. As such, the scientific community sets minimum limits on ventilation with the idea that increased ventilation reduces pathogen concentration and thus reduces the risk of transmission. In contrast, the upper limit on ventilation is usually determined by human comfort and the need to reduce energy consumption. While average pathogen concentration decreases with increased ventilation, local concentration depends on multiple factors and may not follow the same trend, especially within short exposure times over large separation distances. Here, we show through experiments and high-fidelity simulations the existence of a …

Anthropology Faculty Publications

Following the authorization of the use of COVID-19 vaccines in babies age 6 months through children 4 years old in the United States, some individuals (parents, pediatricians, and communicators) framed COVID-19 vac-cination as an issue of access, while many others expressed hesitancy, and some resisted recommendations from the US Centers for Disease Control and Prevention. In this context, this study aimed to explore: 1) divergent reactions to the authorization of COVID-19 vaccine use in children aged 6 months to 4 years; and 2) opposing logics underlying attitudes towards pro-vaccination, anti-vaccination, and vaccine hesitancy regarding COVID-19 vaccines. To achieve this, a …

Clinical Characteristics Of Idiopathic Granulomatous Mastitis In A Hispanic Border Population: A Case Series And Literature Review, Percy M. Thomas, Laura R. Uribe, Aminadab G. Flores, Emilia C. Dulgheru

School of Medicine Publications

Idiopathic granulomatous mastitis (IGM) is an autoimmune condition of the breast that is commonly encountered in women of non-white ethnicity such as Southeast Asians, Middle Easterners, and Hispanics. This condition often presents as a painful breast mass, and many patients undergo invasive diagnostic procedures or surgical excision, which can lead to disfiguring scars. Early recognition and prompt treatment with immunosuppressive medications can prevent invasive workups and management. Although previously thought to require an exclusively surgical approach, it now prompts interdisciplinary management. In this context, we present a case series of patients with IGM in a Hispanic population of South Texas.

Unmasking The Chameleon: A Rare Case Of Generalized Bullous Fixed Drug Eruption, Christopher Reid-Gordon, Aishwarya Gatiganti, Jose E. Campo Maldonado

Research Symposium

Background: Fixed drug eruption (FDE) is a unique dermatological drug reaction known for its recurrence in identical locations upon re-exposure to the causal drug. Acute FDE typically manifests a single or a small number of dusky red or violaceous plaques that, once resolved, leave post-inflammatory hyperpigmentation.

The case we present involves a patient with maculopapular bullous rash on his back, chest, and extremities. The rash was initially misdiagnosed as Chickenpox, yet a skin biopsy indicated Bullous Drug Eruption as a more likely diagnosis. This case is novel as the patient’s medical history did not reveal any previous intake of drugs …
