Irritable Bowel Syndrome (IBS) is a common gut disorder that affects approximately 11% of the global population and negatively affects the quality of life of patients and imposes a significant socioeconomic burden. A control-based study was conducted on 42 Iraqi patients with IBS who presented at private clinics for gastrointestinal diseases (GIDs), along with 20 healthy individuals matched in age and gender to act as a control group. The study aimed to determine the frequency of IBS among Iraqi patients, as well as the influence of biomarkers on the disease's initiation, type, and severity such as IL-1ß, anti-Cytolethal distending toxin …

The Relationship Between The Nervous System And Dna Expression(A Review), Maha Raad Hashim Al-Sammarraie, Yasir Khaleel Almusawi, Mukaram D. Shikara

Al-Esraa University College Journal for Medical Sciences

Neurotransmitters travel through synapses mediated by neurons. The DNA inside the neurons does not replicate since it arrests in the G1 phase of the cell cycle, which explains the absence of replication as DNA replication occurs during the S phase, which is preceded by the G1 phase. Experiments have shown that environmental factors can influence the DNA code and have been tried in both plant and animal kingdoms over the last two centuries with great success, leading to the belief that environmental factors can prompt the brain to send signals (neurotransmitters) to somatic cells. The next question will be: "Is …

Hepatitis B Virus And B-Cell Lymphoma: Evidence, Unmet Need, Clinical Impact, And Opportunities, Maya Rosenberg, Maria Poluch, Colin Thomas, Paola Sindaco, Alan Khoo, Pierluigi Porcu

Kimmel Cancer Center Faculty Papers

Nearly a billion people worldwide are infected with the hepatitis B Virus (HBV) and about a third of them have chronic infection. HBV is an important cause of morbidity and mortality, including acute and chronic hepatitis and hepatocellular carcinoma (HCC). Screening and control of primary HBV infection through vaccination represent a major advance in global public health, but large sections of the world population, in both developed and underdeveloped countries, remain unscreened and unvaccinated. In addition to being a global cause of liver disease, an important role of HBV in lymphoma has also emerged. First, the high risk of HBV …

Kaposi sarcoma (KS), a multifocal vascular neoplasm frequently observed in HIVpositive individuals, primarily affects the skin, mucous membranes, visceral organs, and lymph nodes. KS is associated primarily with Kaposi sarcomaassociated herpesvirus (KSHV) infection. In this case report, we present a rare occurrence of co-infection and co-localization of KSHV and Epstein-Barr virus (EBV) in KS arising from the conjunctiva, which, to our knowledge, has not been reported previously. Immunohistochemistry (IHC), DNA polymerase chain reaction (PCR), and EBV-encoded RNA in situ hybridization (EBER-ISH) were utilized to demonstrate the presence of KSHV and EBV infection in the ocular KS lesion. Nearly all KSHV-positive …

Altered myeloid inflammation and lymphopenia are hallmarks of severe infections. We identified the upregulated EN-RAGE gene program in airway and blood myeloid cells from patients with acute lung injury from SARS-CoV-2 or other causes across 7 cohorts. This program was associated with greater clinical severity and predicted future mechanical ventilation and death. EN-RAGEhi myeloid cells express features consistent with suppressor cell functionality, including low HLA-DR and high PD-L1. Sustained EN-RAGE program expression in airway and blood myeloid cells correlated with clinical severity and increasing expression of T cell dysfunction markers. IL-6 upregulated many EN-RAGE program genes in monocytes in vitro. …

Cardiac-derived c-kit+ progenitor cells (CPCs) are under investigation in the CHILD phase I clinical trial (NCT03406884) for the treatment of hypoplastic left heart syndrome (HLHS). The therapeutic efficacy of CPCs can be attributed to the release of extracellular vesicles (EVs). to understand sources of cell therapy variability we took a machine learning approach: combining bulk CPC-derived EV (CPC-EV) RNA sequencing and cardiac-relevant

Clinically Applied Anthropology: A Syndemic Intervention., Jason W. Wilson

USF Tampa Graduate Theses and Dissertations

This dissertation demonstrates that a critical, clinically applied anthropology is possible by testing a hypothesis that a syndemic intervention, and use of a structural vulnerability assessment tool, can achieve improved healthcare outcomes. A critical, clinically applied anthropology integrates social scientists into healthcare delivery, alongside biomedical providers, through the co-creation of new diagnostic and patient care pathways that utilize anthropological methods (ethnographically informed care, syndemics, thematic/mixed methods data analysis) and advance anthropological theory (biomedicine and culture, structural violence, structural competency/vulnerability, ontology, assemblage theory, and entanglements) to decrease healthcare inequities.

Medical anthropology has previously engaged biomedicine and other attempts at a clinical …

Direct And Indirect Effects Of Recreational Marijuana On Physical, Mental, Gestational, And Developmental Health: A Point Of Care Handout, John C. Lowman

Doctoral Dissertations and Projects

Review of current research on cannabis use indicates a knowledge gap among caregivers and the need for a tool making it easier to share accurate information with patients. A single-page point-of-care handout, similar to that used to advise the public about cigarette smoking, can help fill that gap. Metadata review of 76 articles was used to build a survey completed by 18 emergency room personnel (physicians, nurses, techs, hands-on administrators) before and after a brief presentation of the handout. Data analysis indicates the presentation increased awareness of marijuana use and health effects an average of 35.7%; level of comfort discussing …

Understanding metal-metal bonding involving f-block elements has been a challenging goal in chemistry. Here we report a series of mixed-valence di-metallofullerenes, ThDy@C2n (2n = 72, 76, 78, and 80) and ThY@C2n (2n = 72 and 78), which feature single electron actinide-lanthanide metal-metal bonds, characterized by structural, spectroscopic and computational methods. Crystallographic characterization unambiguously confirmed that Th and Y or Dy are encapsulated inside variably sized fullerene carbon cages. The ESR study of ThY@D3h(5)-C78 shows a doublet as expected for an unpaired electron interacting with Y, and a SQUID magnetometric study of ThDy@ …

Early Resveratrol Treatment Mitigates Joint Degeneration And Dampens Pain In A Mouse Model Of Pseudoachondroplasia (Psach), Jacqueline T Hecht, Alka C Veerisetty, Debabrata Patra, Mohammad G Hossain, Frankie Chiu, Claire Mobed, Francis H Gannon, Karen L Posey

Faculty, Staff and Student Publications

Pseudoachondroplasia (PSACH), a severe dwarfing condition associated with early-onset joint degeneration and lifelong joint pain, is caused by mutations in cartilage oligomeric matrix protein (COMP). The mechanisms underlying the mutant-COMP pathology have been defined using the MT-COMP mouse model of PSACH that has the common D469del mutation. Mutant-COMP protein does not fold properly, and it is retained in the rough endoplasmic reticulum (rER) of chondrocytes rather than being exported to the extracellular matrix (ECM), driving ER stress that stimulates oxidative stress and inflammation, driving a self-perpetuating cycle. CHOP (ER stress signaling protein) and TNFα inflammation drive high levels of mTORC1 …

Electromagnetic wave absorbing materials (EWAMs) have made great progress in the past decades, and are playing an increasingly important role in radiation prevention and antiradar detection due to their essential attenuation toward incident EM wave. With the flourish of nanotechnology, the design of high-performance EWAMs is not just dependent on the intrinsic characteristics of single-component medium, but pays more attention to the synergistic effects from different components to generate rich loss mechanisms. Among various candidates, carbides and carbon materials are usually labeled with the features of chemical stability, low density, tunable dielectric property, and diversified morphology/microstructure, and thus the combination …

Image-based AI has thrived as a potentially revolutionary tool for predicting molecular biomarker statuses, which aids in categorizing patients for appropriate medical treatments. However, many methods using hematoxylin and eosin-stained (H&E) whole-slide images (WSIs) have been found to be inefficient because of the presence of numerous uninformative or irrelevant image patches. In this study, we introduced the region of biomarker relevance (ROB) concept to identify the morphological areas most closely associated with biomarkers for accurate status prediction. We actualized this concept within a framework called saliency ROB search (SRS) to enable efficient and effective predictions. By evaluating various lung adenocarcinoma …

Molecular Regulation Of Neutrophil Swarming In Health And Disease: Lessons From The Phagocyte Oxidase, Zhimin Song, Sourav Bhattacharya, Regina A Clemens, Mary C Dinauer

2020-Current year OA Pubs

Neutrophil swarming is a complex coordinated process in which neutrophils sensing pathogen or damage signals are rapidly recruited to sites of infections or injuries. This process involves cooperation between neutrophils where autocrine and paracrine positive-feedback loops, mediated by receptor/ligand pairs including lipid chemoattractants and chemokines, amplify localized recruitment of neutrophils. This review will provide an overview of key pathways involved in neutrophil swarming and then discuss the cell intrinsic and systemic mechanisms by which NADPH oxidase 2 (NOX2) regulates swarming, including modulation of calcium signaling, inflammatory mediators, and the mobilization and production of neutrophils. We will also discuss mechanisms by …

Determining The Ideal Concentrations Of Ethanol And Propylene Glycol In Ethosomes For Transdermal Delivery Of Vitamin D3, Rebecca Conner

Harrisburg University Research Symposium: Highlighting Research, Innovation, & Creativity

Vitamin D₃ is an important chemical in the human body, however, many Americans have low levels of this vitamin. There are plenty of oral supplementations for Vitamin D₃ deficiency, but those of older age and busy schedules may struggle to meet the minimum requirement. A recently developed ethosomal transmembrane delivery system (Touitou, 2000), similar to liposomes but also containing ethanol, allows users to apply a gel dermally and have the desired drug or active ingredient reach the bloodstream faster. However, there is considerable variation in the concentration of ethanol and permeation enhancers used. Using an affordable method to …

Medical tourism is a process in which a consumer travels from one’s health jurisdiction to receive biomedical treatments or services, thus becoming a patient. This chapter explores how global media frame cases of patient death associated with the medical tourism (MT) process between 2009-2019. A qualitative content analysis of 50 patient mortality cases found that (1) a majority of media representations of medical tourism patient death are of middle-class, minority females between 25-55 years of age seeking cosmetic surgery internationally; (2) sudden death, grief, and bereavement counseling is noticeably absent from medical tourism providers (MTPs); and (3) the acknowledgement of …

Antiviral Treatment Of Maternal And Congenital Cytomegalovirus (Cmv) Infections, Swetha Pinninti, Suresh Boppana

APC Fund

Human Cytomegalovirus (HCMV) is a ubiquitous member of the Herpesviridae family, responsible for the most common congenital viral infection—congenital Cytomegalovirus (cCMV) infection. While a majority of HCMV infections in children and adults are asymptomatic, HCMV is well known to cause severe infections in the immunocompromised individual and maternal infections with variable long-term sequelae after maternal–fetal transmission with primary or nonprimary infections. HCMV seroprevalence and cCMV incidence vary by geographic area and demographic characteristics like race and socioeconomic status. While cCMV birth prevalence ranges from 0.2% to 6% in different parts of the world, it is influenced by regional HCMV seroprevalence …
