Parental experience of their child’s cancer diagnosis as a predictor of health anxiety
(Oklahoma State University, 2023-04-27)Following a child’s pediatric cancer diagnosis, both the child and parent experience significant psychological stress. Several factors, such as cognitive appraisal mechanisms, demographic variables, stress, anxiety, and ... -
Perceptions of science communication by professional communicators
(Oklahoma State University, 2023-04-18)Scientific progress by itself is not enough to move society forward. As an example, measles was basically eradicated in the United States only to make a comeback because of declining vaccination rates (Patel et al., 2019). ... -
Phylogeny of Sonoran Desert milkweeds resolved with plastid genome sequences
(Oklahoma State University, 2019-04-27)The Sonoran Desert Clade milkweeds have very unusual traits, including species that are nearly leafless and shrubby. This clade includes 9 species for which we estimate a phylogenetic tree and use this information to better ... -
Phytochemical profile of a bread wheat family segregating for purple, red, and white kernel color
(Oklahoma State University, 2022-04-19)Anthocyanins are plant compounds that cause the red and purple pigmentation in blueberries and raspberries. They can function as antioxidants which have been shown to have health benefits by protecting human cells from ... -
Pitfalls of persuasion through the lens of Scientology
(Oklahoma State University, 2023-04-18)No one ever expects to join a cult. Further, no one wants to join a cult. High control groups know this, and they use it to manipulate all kinds of unsuspecting people. Scientology is a cult and its various leaders have ... -
Predator-prey interactions with Physa acuta
(Oklahoma State University, 2019-04-27)Freshwater communities can be complex with the predatory strategies that take place within them. Gastropods are an example of a typical prey that is found within these freshwater communities. Their predators give off a ... -
Preliminary exploration of molecular mechanism of the anticancer activity of a novel lead lactate dehydrogenase inhibitor against pancreatic cancer
(Oklahoma State University, 2021-10-09)Pancreatic ductal adenocarcinoma (PDAC) is a leading cause of cancer-related death in the United States, with a long-term survival rate of just under 10%. Chemotherapy is one of the standard treatment options for pancreatic ... -
Preliminary findings regarding student learning from lecture and homework
(Oklahoma State University, 2023-04-18)Lectures and homework both provide opportunities for students to learn mathematics. Researchers have focused on learning from lectures (e.g., Krupnik et al., 2018; Lew et al., 2016; Lew & Zazkis, 2019) and from homework ... -
Preventive effects of red ginseng on an aging hallmark - senescence
(Oklahoma State University, 2023-04-27)By 2030, 1 in 6 people in the world will be aged 60 years or older, increasing the importance of interventional therapies for age-associated diseases. Research investigating cultural dietary differences recognized that the ... -
PtsI independently regulates cell length and width through multiple metabolic and signaling pathways
(Oklahoma State University, 2023-04-18)It has been long known that Escherichia coli can adjust its cell size and growth rate to nutrient availability. Several proteins, such as OpgH (which modulates cell division based on UDP-glucose concentration), and pyruvate ... -
Quantifying the effect of methane production on surrounding soil atmospheric gas exchange
(Oklahoma State University, 2021-04)By observing the behavior of soil microorganisms with respect to proximity to a methane production site (dairy farm lagoon), the relationship between anthropogenically manipulated atmospheric methane levels and methane ... -
Quantifying the shifted baseline in breeding bird communities for Native American tribes relocated to Oklahoma
(Oklahoma State University, 2019-07-25)Ecosystem services are often recognized for their importance in productivity (e.g., Nitrogen fixation) or biosphere support (Oxygen production from photosynthesis). Cultural ecosystem services (e.g., biodiversity appreciation) ... -
