Comparing Depression, Anxiety, and Stress in Male vs Female Collegiate Student Athletes during the COVID-19 Pandemic

Looked at the rates of depression, anxiety and stress using the DASS-21 in college athletes during COVID-19. Looked at the difference between males and females over time. Results show there was no significant difference between male and females at PLNU during that time.


Performance Block Prevalence and Contributing Factors in Individualized versus Team Sports

Performance block is a blanket term that research is trying to propose to replace sport specific terms such as yips, mental block, or lost move syndrome. Though symptoms may present slightly different between the sport specific terms, they all have the same core experience of a sudden inability to perform a previously automatic skill. This study compared performance block prevalence between individual and team sports at PLNU and found similar results.


Ball Speed Predictors in One-Legged Attacks in Female Volleyball Players

Previous literature in volleyball biomechanics highlighted jump height and ball speed as key determinants for the success of regular spikes. To further current research and provide athletes and coaches with direct parameters for proper execution of more complex volleyball attacks, ball speed predictors of a slide attack were investigated.


Perception of Depression, Anxiety, and Stress in Student-Athletes Before and After Return to Campus Following COVID-19 Induced Social Isolation

To analyze the mental health status of student-athletes following COVID-19 induced social isolation, perceptions of depression, anxiety, and stress were measured before and after athletes return to campus. Methods: One hundred fourteen NCAA Division II student-athletes took the DASS-21 questionnaire in the Fall semester of 2020 and again in the Spring semester of 2021. Results: Between T1-T2 there were significantly lower scores of depression (p < 0.001) and stress (p < 0.001), but not anxiety (p = 0.107).


Expression of PDZ domain 1 of the Scribble Polarity Complex

Infection by high-risk human papillomavirus (HPV) is the leading cause of cervical cancers. This study establishes a protocol for the expression of a host-cell protein domain targeted by HPV. This will be valuable for future research into the cellular mechanism of HPV and the development of therapies against cervical cancer in infected individuals.



DNA Methylation and Phenotypic Plasticity in Tomatoes and Peppers

This study examines the relationship between the epigenetic mechanism of DNA methylation and phenotypic plasticity, a measure of adaptability, in tomatoes and sweet peppers.


Degradation of pRb by Retrovirally Infected Cell Lines

The human papillomavirus (HPV) contains hundreds of serotypes that have been divided into low-risk versus high-risk variants. Whereas low-risk serotypes have been shown to cause benign skin lesions, the high risk serotypes are associated with various types of cancer, including cervical cancer. Research has demonstrated that high-risk HPV encodes an oncoprotein E7 that binds to and degrades the tumor suppressor retinoblastoma protein pRb. This project investigated the use of retroviral infection to establish a stable cell line to be characterized via western blot protein analysis.


Long Term Consequences of Repeated Brain Injury - A Cadaveric Study

The purpose of this paper was to examine the long term consequences of repeated brain injury through a cadaveric dissection. For this literature review, the limbic system will be the anatomical structure of focus. In particular, this paper will examine the effects of mild and traumatic brain injury.


Fate of Acrolein, an Agricultural Biocide, Overtime

Acrolein is an efficient agricultural herbicide within irrigation canal ditches and a biocide within oilfield water-flood systems. The fate of acrolein is typically attributed to evaporation, however, it is found that acrolein also dimerizes in water. This hetero-Diels-alder product is stable over an extended period of time, thus losing its original function as an effective biocide and herbicide. Various 1D/2D NMR and GC-EIMS techniques were used to elucidate the structure of said dimerization product, found to be 5,6-dihydro-2H-pyran-3-carbaldehyde.
