Variability Of Grazing By Appendicularians On Prochlorococcus, Carey Sweeney 2024 Portland State University

Variability Of Grazing By Appendicularians On Prochlorococcus, Carey Sweeney

Student Research Symposium

The marine picocyanobacterium, Prochlorococcus is the most abundant photosynthetic cell on Earth. These cells are critical to global primary productivity and are critical to biogeochemical cycles of the open ocean. While abiotic environmental factors that influence Prochlorococcus are relatively well-understood, biotic controls, especially predation, are not well-studied. Appendicularians are ubiquitous invertebrate grazers that feed on microbes including Prochlorococcus in the open ocean. However, the details of this feeding interaction have not been characterized. In a laboratory study, I showed that prey retention of Prochlorococcus increases as the life stage of the appendicularians advances and increases with increasing concentration of prey. …

The Influence Of A Ubiquitous Filter Feeder On Coastal Microbial Communities., Melissa Steinman, Moritz S. Schmid, Robert K. Cowen, Su Sponaugle, Kelly R. Sutherland, Anne W. Thompson

Student Research Symposium

Doliolids have a unique ability to impact the marine microbial community through bloom events and high filtration rates. Their predation on large eukaryotic microorganisms is established and evidence of predation on smaller prokaryotic microorganisms is beginning to emerge. We studied the retention of both eukaryotic and prokaryotic microbial taxa by wild-caught doliolids in the northern California Current system. We use qPCR to quantify the impact of doliolids on three important and globally abundant taxa: Synechococcus, SAR11 and diatoms. Doliolids were collected during bloom events identified at three different shelf locations with variable upwelling intensities. We discovered that in addition …


Understanding The Importance Of Social Emotional Learning In Children And The Link Between Mental Health, Lynette Marie Lubiak 2024 Portland State University

Understanding The Importance Of Social Emotional Learning In Children And The Link Between Mental Health, Lynette Marie Lubiak

Student Research Symposium

I will examine how very important it is to society to teach structured Social Emotional Learning (SEL) programs to children in school. It can bring mental wellbeing and the ability to have healthy relationships, non addictive behaviors and being able to emotionally regulate themselves. Since we have pushed on only academia and not SEL for our children, mental illness has skyrocketed. This problem started after the SEL part of school was taken out of schools and then the division between rich and poor became wider and wider as time went on. If we were to bring back SEL into school, …


Phytoplankton Community Dynamics In The Northern California Current System, Kristin Forgrave 2024 Portland State University

Phytoplankton Community Dynamics In The Northern California Current System, Kristin Forgrave

Student Research Symposium

The Northern California Current system is a productive coastal ecosystem that encompasses a variety of temporal and spatial features. The photosynthetic microbial community plays a crucial role in supporting the rich ecosystem and economically important fisheries. My research integrates data across distance and two years to investigate the community composition of two major phytoplankton groups in this system: picocyanobacteria and picoeukaryotes. The abundances and sizes of the phytoplankton were measured using flow cytometry. Picoeukaryotes were found to be present at similar concentrations in both summer and winter. Abundances of both cell types were comparable in the winter, but picocyanobacteria were …

Autism Risk Gene Cul3 Alters Neuronal Morphology Via Caspase-3 Activity In Mouse Hippocampal Neurons, Qiang-Qiang Xia, Anju Singh, Jing Wang, Zhong Xin Xuan, Jeffrey D. Singer, Craig M. Powell

Biology Faculty Publications and Presentations

Autism Spectrum Disorders (ASDs) are neurodevelopmental disorders (NDDs) in which children display differences in social interaction/communication and repetitive stereotyped behaviors along with variable associated features. Cul3, a gene linked to ASD, encodes CUL3 (CULLIN-3), a protein that serves as a key component of a ubiquitin ligase complex with unclear function in neurons. Cul3 homozygous deletion in mice is embryonic lethal; thus, we examine the role of Cul3 deletion in early synapse development and neuronal morphology in hippocampal primary neuronal cultures. Homozygous deletion of Cul3 significantly decreased dendritic complexity and dendritic length, as well as axon formation. Synaptic spine density significantly …

The Trnaval Half: A Strong Endogenous Toll-Like Receptor 7 Ligand With A 5′-Terminal Universal Sequence Signature, Kamlesh Ganesh Pawar, Takuya Kawamura, Yohei Kirino

Computational Medicine Center Faculty Papers

Toll-like receptors (TLRs) are crucial components of the innate immune system. Endosomal TLR7 recognizes single-stranded RNAs, yet its endogenous ssRNA ligands are not fully understood. We previously showed that extracellular (ex-) 5'-half molecules of tRNAHisGUG (the 5'-tRNAHisGUG half) in extracellular vesicles (EVs) of human macrophages activate TLR7 when delivered into endosomes of recipient macrophages. Here, we fully explored immunostimulatory ex-5'-tRNA half molecules and identified the 5'-tRNAValCAC/AAC half, the most abundant tRNA-derived RNA in macrophage EVs, as another 5'-tRNA half molecule with strong TLR7 activation capacity. Levels of the ex-5'-tRNAValCAC/AAC half were highly up-regulated in macrophage EVs …

Agreement Of Air Bike And Treadmill Protocols To Assess Maximal Oxygen Uptake: An Exploratory Study, Travis Lipscomb, Megan Sax Van Der Weyden, Ali Boolani, Bryan St. Andrews, Joel Martin

International Journal of Exercise Science

International Journal of Exercise Science 17(4): 633-647, 2024. Maximal oxygen consumption (V̇O2max) is an important measure of aerobic fitness, with applications in evaluating fitness, designing training programs, and assessing overall health. While treadmill assessments are considered the gold standard, airbikes (ABs) are increasingly popular exercise machines. However, limited research exists on AB-based V̇O2max assessments, particularly regarding agreement with treadmill graded exercise tests. To address this gap, a randomized crossover study was conducted, involving 15 healthy adults (9M, 6F, 7 familiar with AB) aged 30.1 ± 8.6 years. Paired t-tests, intraclass correlation coefficients (ICC), Bland-Altman and Principal component …
