50 88 ratios for each parameter have been evaluated to tissue depths of 0.5 mm and 2.5 mm. Results for participants who were under age 30 showed that the FF ratio determined for a depth of 2.5 mm was 1.003 ± 0.146 (mean ±SD). Conclusion. Present findings suggest that using a 2SD threshold and based on the under 30 data, a measured FF ratio greater than 1.300 in an individual would be taken as an indication of the presence of lower extremity edema. This threshold may subsequently be refined pending further data.

Determine the extent of homology and gene expression between elasmobranch and human DNA Nucleotide Excision Repair (NER) genes. Background. Shark and Ray species have lifespans that range from 3-350 years. DNA repair capacity has been correlated with the length of life from vertebrate species that live on land. For the first time a study of DNA repair gene homology and expression will be performed on sharks and rays. We hypothesize that these species will show significant homology in NER genes with human. We further hypothesize that the expression of NER genes will correlate with the lifespan of the species. Methods. RNA sequencing is being used to determine the extent of gene expression in each species and the sequence of the exons in each of the 20 canonical NER genes. Results. Elasmobranch NER genes have never been studied. Results are currently being assessed using a skate and an elephant shark reference genome to assess RNA sequencing data from 3 nurse sharks and 3 yellow rays for the identification of the NER genes from shark and ray samples. Homologies to human are forthcoming as well as gene expression data. Conclusion. The NTA breast represents a preneoplastic stage in breast carcinogenesis. Two different types of NTA have been identified with regard to DNA repair. Grant. PFRDG funded 2017 (Kerstetter). Atrium – Poster 45 12:15-1:15 p.m. Drowning Awareness Emily M.

There are two common forms of drowning known as dry drowning and near drowning. Dry drowning involves water being found within ones lungs without being under water. This form of drowning occurs twenty-four hours after swimming. Near drowning is the process of almost dying due to being submerged under water. Incidences of drowning continue to rise within the healthcare field especially amongst children. The American National Red Cross provides a guideline to help limit the amount of risks for drowning. Many times when children have been involved in drowning is due to lack of knowledge about proper ways to swim. Also, encompassing a lack of supervision. Nurses play a vital role in providing the utmost care for children who have been involved in a drowning incident. Providing proper education about swimming and ways to minimize the risk for drowning can reduce the amount of drowning occurrences. Overall, drowning continues to be on the rise and needs to be properly addressed by health care professionals to reduce the amount of fatal and non-fatal drowning events.
