Karbala International Journal of Modern Science

The spike (S) protein is a major antigenicity site that targets neutralizing antibodies and drugs. The growing number of S protein mutations has become a severe problem for developing effective vaccines. Here, we investigated four severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants that were the most infectious and widespread during the COVID-19 pandemic to determine the trends and patterns of mutation-induced changes in the stability, B-cell epitope, and antigenicity of the SARS-CoV-2 S protein. The data showed that the Beta and Gamma variants had three mutations on the receptor-binding domain (RBD), which is the specific site on the S …

Anthelmintic Resistance In Sheep Across Ireland And The Uk: A Literature Review Of The In Vivo Versus In Vitro Methods, Megan Tumulty

SURE Journal: Science Undergraduate Research Experience Journal

Background: The animal welfare and production consequences of gastrointestinal nematode infections, namely Nematodirus battus, on sheep are compelling. The control of gastrointestinal infections has been heavily reliant on the administration of anthelmintics since their introduction into mainstream use in 1960. However, their frequent and often excessive use has resulted in anthelmintic resistance being reported extensively in several gastrointestinal nematode species. The prevalence of anthelmintic resistance as well as the increase in the number of cases of multiple-drug resistance in nematode populations now poses substantial hindrance on the viability of sheep production systems. However, despite the threat N. battus poses …

Long-Term Dynamics Of The Kidney Disease Epidemic Among Hiv-Infected Individuals, Heather Gudaz, Henry A. Ogu, Elissa J. Schwartz

Spora: A Journal of Biomathematics

One of many risks facing HIV+ individuals is the development of kidney dysfunction and end stage kidney disease (ESKD). A differential equation-based mathematical model was developed to assess the impact of antiretroviral therapy on the progression to kidney disease and on reducing mortality due to kidney failure. Analytical and numerical predictions of long-term HIV+ ESKD prevalence show that therapy can lead to either extremely low levels of disease prevalence or increased prevalence, depending on drug efficacy levels and mechanisms of action. Maintenance of HIV+ ESKD prevalence below one individual is possible with sufficient efficacy (e.g., 99%) against the progression from …

Disease-Causing Fungi In Homes And Yards In The Midwestern United States, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

A number of fungal pathogens that may result in a variety of human diseases are found in residential homes and yards. The growth of these microscopic fungi is often favored by particular characteristics of the dwelling and nearby outdoor environment. Evolved virulence factors or increased ability of specific fungi to grow in diverse, and sometimes harsh, microenvironments presented by the domestic environment may promote growth and pathogenesis. Infection may occur by inhalation or direct inoculation and include endemic fungi in addition to opportunistic or emerging species. Systemic or locally aggressive fungal infections are particularly likely and may be life-threatening in …

Autoantibodies To The Ny-Eso-1 Tumor Antigen In Metastatic Melanoma: Sialylation Of The Fc Region Of Immunoglobulin G Induces Differential Expression Signatures Of Inflammatory Molecules During Dendritic Cell Differentiation And Maturation, Martin Oaks, Nathaniel Rein, John O. Richards, James Shaffer

Journal of Patient-Centered Research and Reviews

Purpose: We tested the hypothesis that different glycoforms of antibodies from patients with metastatic melanoma have different functional effects on human dendritic cell differentiation and maturation.

Methods: Antibodies to the cancer antigen NY-ESO-1 were affinity-purified from patients with melanoma and further fractionated into different glycoforms by lectin chromatography. Sialic acid-rich and sialic acid-poor fractions of these immunoglobulin G antibodies (IgG) were added to dendritic cell cultures during both differentiation and maturation, and the resulting cellular messenger RNA (mRNA) and culture supernatants were tested by microarray and enzyme-linked immunoassay for molecules related to inflammatory pathways.

Results: We identified unique mRNA and …

Fty720 (Fingolimod) Provides Insight Into The Molecular Mechanisms Of Multiple Sclerosis, Madelyn Elizabeth Crawford

Pursuit - The Journal of Undergraduate Research at The University of Tennessee

Multiple sclerosis (MS) is a neurodegenerative disorder caused by a prolonged immune- mediated inflammatory response that targets myelin. Nearly all of the drugs approved for the treatment of MS are general immunosuppressants or only function in symptom management. The oral medication fingolimod, however, is reported to have direct therapeutic effects on cells of the central nervous system in addition to immunomodulatory functions. Fingolimod is known to interact with sphingosine-1-phosphate (S1P) receptors, and the most widely- accepted theory for its mechanism of action is functional antagonism of the receptor. This review examines significant neuromodulatory effects achieved by functional antagonism of the …

New immunotherapy cancer treatments, where biologic agents are given to patients to influence the body’s natural immune response, are being researched. Among these immunotherapy treatments are co-inhibition blockade of T cells, and combination blockade treatments together with chemotherapy treatment. This review will discuss T cell activation and the role of T cell coinhibitors such as CTLA-4 and PD-1 …

Efficacies Of Fenbendazole And Albendazole In The Treatment Of Commercial Turkeys Artificially Infected With Ascaridia Dissimilis, Jessica Perkins, Tom Yazwinski, Chris Tucker

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The goal of this research was to determine the extent of resistance that turkey roundworms, Ascaridia dissimilis, have developed to anti-parasitic chemicals used in commercial poultry operations. Roundworm infections in turkeys have resulted in monetary losses for the poultry industry for years, generally due to poor feed conversion. The infection itself is subclinical and many turkeys have a light to moderate worm burden. Since parasitisms are light, this leads to the infections being noticed only during processing. Ascaridia dissimilis infections consist of adult worms and developing larvae with the latter comprising most of the worm burden and causing the most …

Aids: Prophecy And Present Reality, Victor De Gruttola, William Ira Bennett

New England Journal of Public Policy

Mathematical modeling of the AIDS epidemic can be useful for policymakers even though precise projections are not possible at this time. Models are useful in establishing ranges for current and future prevalence of HIV infection and incidence of AIDS, as well as in predicting the effect of a given intervention strategy. Most decision makers are using models implicitly when they use epidemiological information as a basis for policy; formulating a model explicitly permits examination of the underlying assumptions. By creating and testing a variety of models, an investigator can determine whether the models reflect more the underlying assumptions or the …
