Canine Testes Thin Sections Culture​, Nguyen Khoi Nguyen, Ramanpreet Singh

2023 Symposium

Canine testes thin section culture

Testes tissue culture systems would provide a tool to elucidate spermatogenesis mechanisms, with the aim of genetic preservation of mammals, especially endangered species. Our experiment aims to develop a culture system capable of producing viable mammalian sperm cells in vitro.

Dogs were chosen as the model organism because testes are readily available. Canine testes were obtained from a local veterinary clinic. Thin sections were generated using a commercial electric slicer. They then were cleaned using Dulbecco’s Phosphate-Buffered Saline (DPBS) supplemented with antibiotics then cultured in a modified Tissue Culture Medium 199 (TCM-199). Sections were …

Temperature Changes Seen In Lower Extremities After Cpn Local Anesthetic Block, Lora Asberry

Symposium of Student Scholars

Many older patients often suffer from walking issues such as Drop Foot. Drop Foot is caused by the malfunction of nerves in the foot, resulting in the loss of control of the front foot muscle. Within all of our patients, there has been a common fibular palsy, caused by the entrapment of the peroneal nerve. Due to this, they cannot lift up their foot. Some cases are permanent, while others are temporary. In the temporary cases, we have indicated a Phoenix Sign. The Phoenix Sign indicates that a nerve, presumed to be dead, has the capability to be recessed back …

Maternal Protein Restriction (Mpr): A Risk Factor For Acute Respiratory Distress Syndrome (Ards), Reza Khazaee

Western Research Forum

Background: Acute respiratory distress syndrome (ARDS) is defined as severe lung dysfunction. The lung impairments in ARDS result from alterations to pulmonary surfactant; a lipid-protein mixture coating the inside of the lung and maintains the lungs’ ability to expand easily. Due to a lack of effective pharmacological therapies mortality associated with ARDS is over 30%. Our research focuses on risk factors that indicate a susceptibility to the disease, which could provide new and early therapeutic options. One such potential risk factor is Maternal Protein Restriction (MPR). MPR is defined by low birth weight and contributes to a variety of adult-onset …

Pulmonary Surfactant Fortified With Cath-2 As A Novel Therapy For Bacterial Pneumonia, Brandon J. Baer

Western Research Forum

Background: Bacterial pneumonia is a leading cause of death worldwide, with high mortality rates persisting even after antibiotic treatment. Current treatments for pneumonia involve administration of antibiotics, however after the bacteria are killed they release toxic substances that induce inflammation and lung dysfunction. Host defense peptides represent a potential solution to this problem through their ability to down regulate inflammation. However, effective delivery to the lung is difficult because of the complex branching structure of the airways. My study addresses this delivery problem by using exogenous surfactant, a pulmonary delivery vehicle capable of improving spreading of these peptides throughout the …

Molecular Regulation Of Stem Cell Behavior During Tissue Repair And Cancer Formation, Nestor J. Oviedo

Science Seminar Series

Oviedo will be presenting his work on identifying the mechanisms of adult stem cell fate determination based on their topographical location in the adult body. Understanding stem cell fate determination is crucial because tissue repair and neoplastic growth are greater in anterior than in posterior regions of adult animals. Despite its critical implications for stem cell biology, carcinogenesis and regenerative medicine, this physiological phenomenon has remained overlooked. Recent findings from his group provide intriguing evidence implying DNA repair mechanisms and cellular signaling through post-translational modifications regulate stem cell fate decision depending on their topographical location in the adult body. We …
