Role Of Transient Receptor Potential Channels In Epithelial Morphogenesis In Chick Embryo, Trinity Q. Waddell
Role Of Transient Receptor Potential Channels In Epithelial Morphogenesis In Chick Embryo, Trinity Q. Waddell
Theses and Dissertations
Transient Receptor Potential channels (TRP) are a superfamily of cationic specific ionchannels that are regulated by various stimuli such as temperature, pH, mechanical stress, ligandsand ion concentration. The role of TRP channels in disease states such as autosomal dominantpolycystic kidney disease, cancer metastasis, and developmental defects lend credence to thebelief that they play an important part in epithelial morphogenesis events. The development ofsomites, neural tube closure and migration of neural crest cells to form things such as the faceand heart is a good developmental model for the aforementioned cellular processes. We haveshown that TRP channels can be found in the …
The Proteomic Response Of Northern Elephant Seal (Mirounga Angustirostris) Pups To Physiological Stress During Development, Melissa P. Voisinet
The Proteomic Response Of Northern Elephant Seal (Mirounga Angustirostris) Pups To Physiological Stress During Development, Melissa P. Voisinet
Master's Theses
Background: Northern elephant seals transition from terrestrial nursing pups to pelagic foraging juveniles in a short period of just 8-12 weeks. During the post-weaning period, pups rely solely on the energy reserves gained during nursing for their caloric demands and water supply. The prolonged absence of food after weaning is the first of many fasts for which the seals have evolved adaptations such as decreased urine production and increased blubber reserves. The stressors experienced from learning to dive for the first time are also stressors that they will experience frequently as an adult and for which they have evolved adaptations. …
The Effects Of Bisphenol F On Embryonic Cardiac Output In Zebrafish, Kyle Monnot
The Effects Of Bisphenol F On Embryonic Cardiac Output In Zebrafish, Kyle Monnot
Williams Honors College, Honors Research Projects
Bisphenol F (BPF) is an analog compound of the xenoestrogen bisphenol A (BPA). BPA utilization has decreased dramatically due to its detrimental effects as an endocrine disrupter. In place of BPA, BPF is growing to be a ubiquitous chemical in epoxy resin manufacturing. Recent research has begun to investigate the possible endocrinal effects of BPF as an analog of BPA. This study was performed to examine the potential effects of BPF exposure on cardiac parameters of zebrafish (Danio rerio) embryos. Embryos were exposed to 50 µg/L BPF for 48 hours, and cardiac parameters (stroke volume, heart rate, and …
Rates Of Water Loss And Metabolism In The Eggs Of Stick Insect Eurycantha Calcarata, Garret K. Jolma
Rates Of Water Loss And Metabolism In The Eggs Of Stick Insect Eurycantha Calcarata, Garret K. Jolma
Undergraduate Theses, Professional Papers, and Capstone Artifacts
The thorny devil stick insect (Eurycantha calcarata) of New Guinea has eggs that take four months or more to develop—incredibly long for an insect. Long development times can be a challenge for eggs because of their finite resources, including nutrients, energy to support development, and water. I investigated the physiological mechanisms underlying long development times in stick insect eggs.
The first experiment examined rates of water loss and survival of eggs held in different experimental humidities (0, 75, or 100% RH). Eggs dried quickly in the 0% humidity “dry” container; and more slowly in the 75% humidity “intermediate” …
