Assessing The Morphology Of Vesicles In Inhibitory Symmetric Synapses In Safety And Fear Conditions In The Rat Lateral Amygdala, Valerie Kress Dec 2019

Assessing The Morphology Of Vesicles In Inhibitory Symmetric Synapses In Safety And Fear Conditions In The Rat Lateral Amygdala, Valerie Kress

Honors Scholar Theses

There is a significant lack of research on vesicle morphology in inhibitory synapses in the rat lateral amygdala. Published research focuses heavily on excitatory synapses in different parts of the rat brain and even this research rarely focuses on the different vesicle types in axons. It is reported that in these axons, synaptic vesicles traditionally contain neurotransmitters while small dense core vesicles contain active zone proteins and large dense core vesicles contain neuropeptides. This study aims to find correlations between vesicle morphology, location, contents, and potential function of each of the different types of vesicle in inhibitory axons.

Development Of A Sonically Powered Biodegradable Nanogenerator For Bone Regeneration, Avi Patel May 2019

Development Of A Sonically Powered Biodegradable Nanogenerator For Bone Regeneration, Avi Patel

Honors Scholar Theses

Background: Reconstruction of bone fractures and defects remains a big challenge in orthopedic surgery. While regenerative engineering has advanced the field greatly using a combination of biomaterial scaffolds and stem cells, one matter of difficulty is inducing osteogenesis in these cells. Recent works have shown electricity’s ability to promote osteogenesis in stem cell lines when seeded in bone scaffolds; however, typical electrical stimulators are either (a) externally housed and require overcomplex percutaneous wires be connected to the implanted scaffold or (b) implanted non-degradable devices which contain toxic batteries and require invasive removal surgeries.

Objective: Here, we establish a biodegradable, piezoelectric …


Embryonic Lethality Of Cranial Neural Crest Deletion Of Cdc73, Lilia Shen May 2019

Embryonic Lethality Of Cranial Neural Crest Deletion Of Cdc73, Lilia Shen

Honors Scholar Theses

Hyperparathyroidism-jaw tumor (HPT-JT) syndrome is a disease characterized by parathyroid tumors, renal cysts or tumors, uterine tumors, and ossifying jaw fibromas. The cause of this syndrome is linked to a tumor suppressor gene called Cdc73, which encodes the protein product parafibromin. The loss of proper expression of Cdc73/parafibromin is implicated in the development of the tumors typical of HPT-JT, although the exact mechanisms of tumorigenesis are unclear. In particular, not much is understood about the development of ossifying fibromas (OF) of the jaw in this syndrome. OF is a benign bone neoplasm that can affect the mandible and …
