Cryopreservation Of Hepatocyte (Hepg2) Cell Monolayers: Impact Of Trehalose, Blake Stokich, Quinn Osgood, David Grimm, Shhyam Moorthy, Nilay Chakraborty, Michael A. Menze

Michael Menze

A simple method to cryogenically preserve hepatocyte monolayers is currently not available but such a technique would facilitate numerous applications in the field of biomedical engineering, cell line development, and drug screening. We investigated the effect of trehalose and dimethyl sulfoxide (Me2SO) in cryopreservation of human hepatocellular carcinoma (HepG2) cells in suspension and monolayer formats. HepG2 cell monolayers were incubated for 24 h at varying concentrations of trehalose (50–150 mM) prior to cryopreservation to identify the optimum concentration for such preincubation. When trehalose alone was used as the cryoprotective agent (CPA), cells in monolayer format did not survive freezing ...


Self-Assembled Gold Nanoplexes For Cancer-Targeted Sirna Delivery, Yongliang Shi 2014 The University of Southern Mississippi

Self-Assembled Gold Nanoplexes For Cancer-Targeted Sirna Delivery, Yongliang Shi

Master's Theses

Through layer-by-layer method, the authors have constructed three Au nanoplexes: AuPEI/RNA/PEI, AuPEI/RNA/PEI-mPEG, and AuPEI/NA/PEI-PEG-FA. All the nanoplexes are characterized by UV-vis spectrometry, DLS, and zeta potential. The surface density of the first layer PEI and second layer RNA were also determined. Moreover, the Au nanoplexes can protect siRNA from RNase degradation and are stable in cell culture medium.

siGLuc-ppp, ssRNA80, and siF17 were delivered by the assembled Au nanoplexes, and the results were analyzed by GLuc assay, TB assay, and Luciferase assay. In terms of RNA delivery, the Au nanoplexes AuPEI/RNA/PEI ...


Experimental Demonstration Of Bindingless Signal Delivery In Human Cells Via Microfluidics, Fang-Tzu Chuang 2014 SelectedWorks

Experimental Demonstration Of Bindingless Signal Delivery In Human Cells Via Microfluidics, Fang-Tzu Chuang

Fang-Tzu Chuang

The cellular signal transduction is commonly believed to rely on the direct “contact” or “binding” of the participating molecule reaction that depends positively on the corresponding molecule concentrations. In living systems, however, it is somewhat difficult to precisely match the corresponding rapid “binding,” depending on the probability of molecular collision, existing in the cellular receptor-ligand interactions. Thus, a question arises that if there is another mechanism (i.e., bindingless) that could promote this signal communication. According to this hypothesis, we report a cellular model based on the examination of intracellular calcium concentration to explore whether the unidentified signal delivery in ...


Affluent Populations And Their Effect On Biological Diversity Through The Consumption Of Meat, Electronics, And Motor Vehicles, Melody Flores 2014 Pace University

Affluent Populations And Their Effect On Biological Diversity Through The Consumption Of Meat, Electronics, And Motor Vehicles, Melody Flores

Honors College Theses

The human has caused a far greater impact on the planet's biodiversity than any other species in existence, due to the impact of population, afflluence, and technology. This thesis will argue the importance of biological diversity and how affluent populations are reducing biodiversity through the consumption of meat, electronics, and motor vehicles. Aldo Leopold's "The Land Ethic" and Herman Daly's "The Impossibility Theorem", among others, create a rubric evaluating human activities and provide alternative views on economic impossibilities. Consumption is reviewed from an ecocentric perspective, a holistic outlook placing emphasis on the ecosystem. The reader will become ...

Developent Of A Phospholipid Encapsulation Process For Quantum Dots To Be Used In Biologic Applications, Logan Grimes

Master's Theses and Project Reports

The American Cancer Society predicts that 1,665,540 people will be diagnosed with cancer, and 585,720 people will die from cancer in 2014. One of the most common types of cancer in the United States is skin cancer. Melanoma alone is predicted to account for 10,000 of the cancer related deaths in 2014. As a highly mobile and aggressive form of cancer, melanoma is difficult to fight once it has metastasized through the body. Early detection in such varieties of cancer is critical in improving survival rates in afflicted patients. Present methods of detection rely on visual ...

Water Water Everywhere: Analyzing Long Island's Water Issues And Finding Solutions For A Sustainable Future, Anthony T. Becker 2014 Fordham University

Water Water Everywhere: Analyzing Long Island's Water Issues And Finding Solutions For A Sustainable Future, Anthony T. Becker

2014 Student Theses

Over three million people call Long Island their home. With access to beautiful landscapes, world-renowned beaches, and proximity to New York City, it is no wonder that so many proudly call this geographic stretch of glacial till their home. However, throughout the years our actions do not necessarily reflect this affection we have to our home. Years of sprawl and human infestation across the island have resulted in widespread environmental degradation. Specifically, the water we drink and the beaches we enjoy have become endangered. I plan on studying the urban ecology of how intensified population growth led to the eutrophication ...


Characterization Of Jumonji-Domain Containing Proteins In Arabidopsis Thaliana, Jennifer Lawson 2014 Syracuse University

Characterization Of Jumonji-Domain Containing Proteins In Arabidopsis Thaliana, Jennifer Lawson

Syracuse University Honors Program Capstone Projects

Jumonji-C (JmjC) domain containing proteins have been shown to play a critical role in regulating gene expression by regulating chromatin remodeling in a variety of organisms. In Arabidopsis, JmjC protein family consists of 21 members, some of which have been shown to be involved in regulating histone demethylation. Most of these proteins have been characterized for their role in regulating plant development, especially for their role in regulating flowering time. Here we report characterization of three JmjC domain containing proteins - JUMONJI1, JUMONJI2, and JUMONJI27 and show that they play a critical role in regulating both pathogen defense and flowering time ...

Effects Of Continuous Combined Oral Contraceptives On Mouse Mammary Gland Structure And Tm2h Mammary Tumor Progression, Evelyn Esteves-Natal 2014 The College at Brockport: State University of New York

Effects Of Continuous Combined Oral Contraceptives On Mouse Mammary Gland Structure And Tm2h Mammary Tumor Progression, Evelyn Esteves-Natal

2014 Master's Level Graduate Research Conference

Cyclic oral contraceptive (OC) use has been associated with increased risk of breast cancer, particularly in African American women, current OC users, and women who begin use early in life. In contrast, the effect of continuous (extended) OC on breast cancer risk is unknown. The purpose of this study was to test the hypothesis that continuous and cyclic OC differ in their effects on mammary gland structure and susceptibility to tumor growth. Starting at day 50 of age, BALB/C mice were fed liquid diets +/- human equivalent doses of ethinyl estradiol and levonorgestrel. After 28 days, 10 mice per group ...

The Role Of Sirtuin 1 And Ceramide In T10C12 Conjugated Linoleic Acid Induced Delipidation In 3t3-L1 Adipocytes, Wei Wang 2014 University of Nebraska - Lincoln

The Role Of Sirtuin 1 And Ceramide In T10C12 Conjugated Linoleic Acid Induced Delipidation In 3t3-L1 Adipocytes, Wei Wang

Theses and Dissertations in Animal Science

Project 1: Trans-10, cis-12 conjugated linoleic acid (t10c12 CLA) reduces triglyceride (TG) levels in adipocytes through multiple pathways, with AMP-activated protein kinase (AMPK) generally facilitating, and peroxisome proliferator-activated receptor γ (PPARγ) generally opposing these reductions. Sirtuin 1 (SIRT1), a histone/protein deacetylase that affects energy homeostasis, often functions coordinately with AMPK, and is capable of binding to PPARγ, thereby inhibiting its activity. This study investigated the role of SIRT1 in the response of 3T3-L1 adipocytes to t10c12 CLA by testing the following hypotheses: 1) SIRT1 is functionally required for robust TG reduction ...

This approach helps communities know how and where to prioritize limited funds in order to achieve the greatest benefit. Often applied to drinking water and wastewater infrastructure, this method is well suited to managing any assets, including stormwater systems.

This issue brief is intended to introduce local governments to the asset management process and to show how it can be applied in managing stormwater assets. It was adapted from an appendix written by ...


Biodynamic Imaging And High-Content Analysis, David D. Nolte 2014 SelectedWorks

Biodynamic Imaging And High-Content Analysis, David D. Nolte

David D Nolte

The existence of phenotypic differences in the drug responses of 3D tissue relative to 2D cell culture is a concern in high-content drug screening. Biodynamic imaging is an emerging technology that probes 3D tissue using short-coherence dynamic light scattering to measure the intracellular motions inside tissues in their natural microenvironments. The information content of biodynamic imaging is displayed through tissue dynamics spectroscopy (TDS) but has not previously been correlated against morphological image analysis of 2D cell culture. In this article, a set of mitochondria-affecting compounds (FCCP, valinomycin, nicardipine, ionomycin) and Raf kinase inhibitors (PLX4032, PLX4720, GDC, and sorafenib) are applied ...
