Nebraska Center for Virology: Faculty Publications

Dysfunction of the homeostasis-maintaining systems in specific cell types or tissues renders the organism susceptible to a range of diseases, including cancers. One of the emerging mechanisms for maintaining tissue homeostasis is cellular senescence. Here, we report that the Hippo pathway plays a critical role in controlling the fate of ovarian cells. Hyperactivation of Yes-associated protein 1 (YAP1), the major effector of the Hippo pathway, induces senescence in cultured primary human ovarian surface epithelial cells (hOSEs). Large tumor suppressor 2 (LATS2), the primary upstream negative regulator of YAP1, is elevated in both YAP1-induced and natural replicative-triggered senescence. Deletion of LATS2 …

Nebraska Center for Virology: Faculty Publications

The substantial genetic diversity exhibited by influenza A viruses of swine (IAV-S) represents the main challenge for the development of a broadly protective vaccine against this important pathogen. The consensus vaccine immunogen has proven an effective vaccinology approach to overcome the extraordinary genetic diversity of RNA viruses. In this project, we sought to determine if a consensus IAV-S hemagglutinin (HA) immunogen would elicit broadly protective immunity in pigs. To address this question, a consensus HA gene (designated H3-CON.1) was generated from a set of 1,112 H3 sequences of IAV-S recorded in GenBank from 2011 to 2015. The consensus HA gene …

Antibiotic Resistance Of Streptococcus Pneumoniae In The United States And Latin American Countries: Contributing Factors And Potential Solutions, Brian Sherman

Theses and Graduate Projects

Antibiotics have been heralded as one of the greatest contributions to modern medicine.

While antibiotics have been documented throughout many parts of the world, it was the discovery of penicillin in 1928 that marked the modern era of medicine.1 An antibiotic is a natural, semi-synthetic, or synthetic compound that interferes with the growth of, or results in the death of a microorganism, specifically bacteria.2 These medications are used to treat or prevent infection of humans or animals. With the advent of antibiotics, many infections that would cause significant morbidity and mortality were greatly reduced. The 1930s-1960s is regarded as the …

Long-Term Outcomes Of Neonatal Herpes Simplex Virus Infection And Treatment, Genesis M. Brador

Honors Undergraduate Theses

The prevalence of herpes simplex virus (HSV) infection globally is high, and although there is no cure for it, the antiviral drug acyclovir is used to alleviate symptoms. There are two types of HSV: HSV-1, which typically infects the oral area, and HSV-2, which is associated with genital infections. A mother who carries the infection may transmit it to a neonate in different ways, most commonly via vaginal delivery in the presence of active lesions. There are three types of HSV disease that affect newborns: skin, eyes or mouth (SEM) disease, central nervous system (CNS) disease, or disseminated disease. The …

Adaptation Of The Streptococcal Collagen-Like Protein 1, Scl1, Of Group A Streptococcus To Recognize Fibronectin Type Iii Repeats, Dudley H. Mcnitt

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: Group A Streptococcus (GAS) is responsible more than 700 million infections worldwide each year. Most of these infections start with initial colonization of the throat and skin, which is augmented by surface adhesins. The streptococcal collagen-like protein 1 (Scl1) is a major adhesin expressed by GAS that contains an N-terminal sequence-variable (V) domain, protruded away from the cell surface by the collagen domain. The Scl-V domain is comprised of three pairs of anti-parallel α-helices interconnected by surface-exposed loops. For attachment, GAS adhesins require a portal of entry, such as a wound or breach in the epithelium, to enter …

Cultural Practices And The Transmission Of Ebola In Sierra Leone: Lessons Learned From A Medical Anthropology Perspective, Abubakarr Jalloh

Dissertations and Theses @ UNI

The link between culture and infectious diseases has long been established. This is primarily due to the notion that culture shapes and influences people’s beliefs, actions, and ways of life. Such beliefs and their accompanying actions ultimately contribute to people’s risk of contracting an infectious disease. As such, there is a need for a cultural perspective in understanding infectious diseases because human behavior plays a significant role in the emergent, transmission, and spread of such diseases. This study explores the cultural practices that may have contributed to the transmission of Ebola Virus Disease (EVD) in Sierra Leone during the 2013-2016 …
