Tunel Apoptotic Cell Detection In Stony Coral Tissue Loss Disease (Sctld): Evaluation Of Potential And Improvements, E. Murphy Mcdonald
All HCAS Student Capstones, Theses, and Dissertations
Stony coral tissue loss disease (SCTLD) is a highly lethal coral disease that has caused a dramatic loss of coral tissue along the Florida Reef Tract and throughout the Wider Caribbean. This study seeks to understand whether programmed cell death (apoptosis) is involved in the pathology of the highly virulent SCTLD tissue loss lesion. Tissues from diseased colonies of Pseudodiploria strigosa collected in 2018 and 2020 were stained using the terminal deoxyribonucleotidyltransferase (TdT) mediated dUTP-biotin nick end labeling (TUNEL) assay to visualize areas of programmed cell death. The archived tissue samples collected in 2018 exhibited a significantly higher degree of …
Expression And Localization Of The 14-3-3 (Ywha) Protein Family Within Mammals, Neha Kumrah, Santanu De
Expression And Localization Of The 14-3-3 (Ywha) Protein Family Within Mammals, Neha Kumrah, Santanu De
Mako: NSU Undergraduate Student Journal
The 14-3-3 (YWHA) are a family of homologous, acidic, and highly conserved proteins expressed abundantly and ubiquitously in a wide array of organisms ranging from plants to animals, including humans, which regulate important cellular events. Within mammals, seven isoforms of 14-3-3 exist: β, γ, ε, ζ, η, τ, and σ (stratifin), each of which is encoded by a unique gene. Studies have shown similar expression patterns among mammalian species. The 14-3-3 proteins are commonly expressed and have proven to play critical roles in proper cellular localization, function, and homeostatic regulation. Numerous researchers have investigated the expression and localization patterns of …

Comparative Study Of The Effects Of Light On Photophore Ultrastructure From Two Families Of Deep-Sea Decapod Crustaceans: Oplophoridae And Sergestidae, Jamie E. Sickles
HCNSO Student Theses and Dissertations
Counterillumination, the mechanism by which pelagic species produce bioluminescence to replace the light blocked by their bodies to hide their silhouettes, has been known for over 100 years. However, little is known about how these animals are able to so precisely replicate the intensity of downwelling light. The recent discovery of opsins in photophores (Bracken-Grissom et al. 2020) suggests that these autogenic organs (i.e. non-bacterial) may be sensitive to light, in addition to their function of emitting visible light. The study presented here is 1) the first ultrastructural assessment of photophores in species Systellaspis debilis, Janicella spinicauda, Parasergestes armatus, …
