YouTube is a free video watching and uploading site that allows endorsing and
sharing of videos. Youth and adolescents as top viewers of YouTube may be exposed to
images and messages on tobacco, marijuana and alcohol use behaviors.
The research project entailed deriving a list of songs from the 2014...
This is a report on the Workforce Development: Youth Training and Work Experience program provided by Casa Latinos Unidos (CLU) in Linn County. The program is best described in three phases. Phase one consisted of the outreach, recruitment, and retainment aspects of the program. The second phase of the program...
Community births are defined as a planned home or birth center birth. Today, the majority of births in the U.S. occur in the hospital, but the U.S. has the highest maternal mortality rates of any developed country. Although community births have comparable outcomes, there is an extreme preference for hospital...
Background:
There are over four billion YouTube views per day with “music” the most searched topic. Among US internet users, 8.3 million YouTube users are under 18 years old. Incorporation of substance use imagery in YouTube videos has a considerable potential influence on young viewing audience behavior. This study identifies...
Genetic code expansion (GCE) is a technology that allows us to incorporate noncanonical amino acids (ncAAs) site-specifically into recombinant proteins using engineered translational machinery. Typically, an orthogonal aaRS/tRNA pair is engineered by directed evolution to recognize the ncAA and incorporate it at a reassigned codon while not interacting with the...
Vitiligo is a disease characterized by depigmented patches of skin. The disease is known to involve the loss of melanocytes in the basal layer of the skin in affected areas, but the underlying mechanisms are unknown. Recent evidence suggests oxidative stress and disruptions to antioxidant pathways contribute to an autoimmune...
Genetic and environmental factors influence individual cancer risk. Mutations in DNA mismatch repair (MMR) genes increase colon cancer risk. Exposure to carcinogens, including the ubiquitous polycyclic aromatic hydrocarbons (PAHs), also is associated with increased cancer risk. To understand the combined effects of both environmental exposures and genetic risk, we investigated...
Cells are constantly bombarded with mutagens, both endogenous and exogenous in origin. Endogenous sources of mutation include reactive oxygen species formed during aerobic respiration, replication errors by DNA polymerase, and spontaneous deamination and depurination (Jackson 2009). Exogenous sources of mutation include UV and ionizing radiation, aflatoxins, and polycyclic aromatic hydrocarbons...
An apparatus and method for calibrating planar laser induced fluorescence using a two-dye, two-color method was developed. A laser sheet was expanded from a 473 nm laser to excite dye solutions into higher energy states then fluoresced through spontaneous emission. The two fluorescent dyes selected for research and development were...
Otoferlin is a protein that is essential in the process of hearing. Mutations in otoferlin are associated with profound recessive deafness. The long-term goal of the Johnson lab is to understand how otoferlin contributes to hearing and why certain mutations result in deafness. This project sought to characterize the difference...
