Bay Leaf Extract‐Based Near‐Infrared Fluorescent Probe For Tissue And Cellular Imaging, Benilde Adriano, Nycol Cotto, Neeraj Chauhan, Vinitha Karumuru, Meena Jaggi, Subhash C. Chauhan, Murali M. Yallapu

School of Medicine Publications

The development of fluorescence dyes for near‐infrared (NIR) fluorescence imaging has been a significant interest for deep tissue imaging. Among many imaging fluoroprobes, indocyanine green (ICG) and its analogues have been used in oncology and other medical applications. However, these imaging agents still experience poor imaging capabilities due to low tumor targetability, photostability, and sensitivity in the biological milieu. Thus, developing a biocompatible NIR imaging dye from natural resources holds the potential of facilitating cancer cell/tissue imaging. Chlorophyll (Chl) has been demonstrated to be a potential candidate for imaging purposes due to its natural NIR absorption qualities and its wide …

Microplastics Fouling And Interaction With Polymeric Membranes: A Review, Mitra Golgoli, Mehdi H. Khiadani, Abdellah Shafieian, Tushar K. Sen, Y. Hartanto, M. L. Johns, Masoumeh Zargar

Research outputs 2014 to 2021

The emergence and accumulation of microplastics (MPs) in various aquatic environments have recently raised significant concerns. Wastewater treatment plants (WWTPs) have been identified as one of the major sources of MPs discharge to the environment, implying a substantial need to improve advanced techniques for more efficient removal of MPs. Polymeric membranes have been proven effective in MPs removal. However, fouling is the main drawback of membrane processes and MPs can foul the membranes due to their small size and specific surface properties. Hence, it is important to investigate the impacts of MPs on membrane fouling to develop efficient membrane-based techniques …

Exploring The Potential Use Of Porous Silica Nanoparticles In Cest-Mri, Lydia Makotamo

Dissertations and Theses

Magnetic resonance imaging (MRI) is a widely used modality in diagnostics, treatment, and monitoring various conditions due to its ability to generate high-resolution images using non-ionizing radiation. The advent of contrast agents, which generally work by increasing the spin relaxation rate constants of water protons, has led to image enhancement. Despite the usefulness of this class of agents in diagnostic medicine, their inability to provide in-depth functional and anatomical information, coupled with their high detection limits, has led to new agents being explored.

Chemical exchange saturation transfer (CEST) presents an alternative route to generate signals via repetitive saturations transfers between …

Preparing For Class: Actions And Resources Of Introductory Biology Students, Tina M. Ballard, Sabah Sattar, Kendra D. Wright, Jaime L. Sabel, Heather E. Bergan-Roller

Faculty Articles, Papers, and Other Scholarship

Instructors want students to be prepared for class. There are several different resources and activities available to help students prepare for class, but very little is known about how students choose to prepare for class in the context of undergraduate biology. In this study, we used content analysis to investigate what students do to prepare for an introductory biology course, and if and how that preparation differed under two different conditions. Students were either directed to search out and choose their resources to prepare for class (choice treatment) or assigned specific pages from a textbook (text treatment). Students in the …

The Role Of Decorin And Biglycan Signaling In Tumorigenesis, Valentina Diehl, Lisa Sophie Huber, Jonel Trebicka, Malgorzata Wygrecka, Renato V. Iozzo, Liliana Schaefer

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The complex and adaptive nature of malignant neoplasm constitute a major challenge for the development of effective anti-oncogenic therapies. Emerging evidence has uncovered the pivotal functions exerted by the small leucine-rich proteoglycans, decorin and biglycan, in affecting tumor growth and progression. In their soluble forms, decorin and biglycan act as powerful signaling molecules. By receptor-mediated signal transduction, both proteoglycans modulate key processes vital for tumor initiation and progression, such as autophagy, inflammation, cell-cycle, apoptosis, and angiogenesis. Despite of their structural homology, these two proteoglycans interact with distinct cell surface receptors and thus modulate distinct signaling pathways that ultimately affect cancer …

Possibilities In Simulated Reality, Yuan Yuan

Theses

This thesis work is based on two simple questions- what is reality, and is there any way to determine if you live in a real world. Whether from ancient times or the present, the east or the west, or fiction movies to philosophical reflection, countless people have ruminated on these questions. The answer seems obvious that reality is anything we can perceive based on our perceptions, but it’s not necessarily factual even though it feels very real. A philosophical viewpoint called epistemological skepticism indicates that we cannot be certain of anything, and there is a philosophy hypothesis named simulation theory …

Community College Geoscience Faculty Perspectives On Critical Thinking Instructional Tools, Mariela Salas Bao

Dissertations and Theses

Research has shown that modern courses and programs designed to foster critical thinking vary in both content and delivery, in turn leading to differences in their effectiveness. Few studies have investigated critical thinking among nontraditional students at community colleges taking STEM courses, especially within the geosciences. Furthermore, such research has focused primarily on the students with few if any studies involving faculty. This study examined the perceptions held by community college geoscience faculty regarding critical thinking and how such perceptions influenced their choice of instructional strategies. This study used a basic qualitative methodology and a maximum variation sampling to select …

Berseem Clover In Binary Mixtures With Oats, Triticale Or Barley For Silage And Late Season Grazing, S. M. Ross, J. R. King

IGC Proceedings (1977-2023)

An experiment was conducted at northerly latitudes with berseem clover (Trifolium alexandrinum L) in binary mixtures with oats (Avena sativa L.), barley (Hordeum vulgare L.) and triticale (X Triticosecale Wittmack). The effects of cereal species, variety and density were assessed for a two cut harvest. Total dry matter yields were 11.7 to 14.5 t ha^-1, with 7.8 to 10.2 t ha^-1 as silage, and 2.0 to 6.0 t ha^-1 as berseem regrowth. Berseem regrowth added an average of 4.0 t ha^-1 in forage yield. Total yields did not differ with cereal …

Forage Productivity Of Panicum Maximum Pastures In Two Different Agropastoral Systems, Tsutomu Kanno, Manuel C. M. Macedo, J. A. Bono, J. D. G. Santos Jr., M. R. Correa, L. G. R. Beretta

IGC Proceedings (1977-2023)

Forage productivity was evaluated for Panicum maximum pastures established after 4 years of soybean cultivation in the summer (PM-SO), and 4 years of rotation of soybeans in the summer and millet for winter grazing (PM-MI). In the PM-MI pasture, biomass and dry matter production were much lower than in the PM-SO, and the amount of copper and nitrogen in the top part of the plants in PM-MI were significantly lower than that in PM-SO. Thus, it was considered that the shortage of copper and nitrogen restricted photosynthesis and forage production in PM-MI.

Nitrogen Mineralization From Root Residues Of Subterranean Clover And Lucerne, T. P. Bolger, J. F. Angus, M. B. Peoples

IGC Proceedings (1977-2023)

To understand why crops grown in the first or second year after lucerne (Medicago sativa L.) yielded less than crops grown after subterranean clover (Trifolium subterraneum L.) despite greater nitrogen (N) fixation by the lucerne, we studied the N mineralization patterns of their root residues in soil incubation assays. Fine roots of both species produced more mineral N than the control soil with no root residues. In contrast, coarse roots mineralized less N than the control soil. These differences in N mineralization were not explained by the physical size and therefore surface area differences between fine and coarse …

"A Year Of Monkey War": The Anti-Evolution Campaign And The Florida Legislature, Mary Duncan France

Florida Historical Quarterly

In the summer of 1925, the world focused its attention on the sleepy town of Dayton, Tennessee, the site of the “Monkey Trial” of John T. Scopes. William Jennings Bryan, former secretary of state and the nation’s most zealous fundamentalist, and Clarence Darrow, the most famous trial attorney of his time, were the real antagonists, as they argued over the issue of the teaching of evolution. Both sides battled as if each believed the trial would produce the definitive statement on God and the creation of man.

Do Consumers Raise Their Voices Or Leave After Service Failures? Examining Angry Rumination, Distraction, And Brand Loyalty, Jungyun "Christine" Hur, Soocheong "Shawn" Jang

Journal of Tourism Insights

This study aims to investigate the influence of rumination and distraction on consumer complaining behaviors (e.g., voice, negative word of mouth, and exiting) in a service failure encounter, and further examine the role of brand loyalty in consumer complaining behaviors. The findings of this study suggest that consumers use rumination and distraction to cope with service failures, which has different influences on consumer complaining behavior. Angry rumination increases all three types of consumer complaining behaviors, whereas distraction reduces negative word-of-mouth only. In addition, these relationships vary across the level of brand loyalty. Loyal consumers are more likely to voice their …

Archived Theses and Dissertations

Cellulolytic enzymes have many industrial applications and play a major role in the process of biofuel production. Bioethanol is a cheap and clean alternative to non-renewable, polluting and expensive fossil fuel. Cellulases and hemicellulases act synergistically to degrade the cellulose polymer into glucose which can then be fermented by specific anaerobic organisms into ethanol. The overall manufacturing process occurs under harsh conditions such as low pH, high temperature and in the presence of elevated salt concentrations. The Atlantis II brine pool in the Red Sea is a unique habitat in terms of its diverse microbial community and physical conditions; high …

Triple Trouble: Examining The Effect Of Combining Mechanical Stress, Pbmcs And Cisplatin On Hepg2 Cell Death, Lalia Ziko

Archived Theses and Dissertations

In an attempt to find better cancer treatments, a new mathematical model proposed by Klika & Marsik (2009) suggests that more cancer cells could possibly be killed by applying several stress factors to tumour cells, however only as a simulation in silico. The proposed stresses include healthy cell anti-tumour effect, the biochemical effect exerted by a cytotoxic drug and a newly introduced mechanical stress. The hypothesis entails that upon applying these three stress factors together simultaneously to tumour cells, the concentration of the tumour cells decreases more than if a stress factor was applied alone. The two main objectives in …

Deep Learning Predicts Ebv Status In Gastric Cancer Based On Spatial Patterns Of Lymphocyte Infiltration, Baoyi Zhang, Kevin Yao, Min Xu, Jia Wu, Chao Cheng

Computer Vision Faculty Publications

EBV infection occurs in around 10% of gastric cancer cases and represents a distinct subtype, characterized by a unique mutation profile, hypermethylation, and overexpression of PD-L1. Moreover, EBV positive gastric cancer tends to have higher immune infiltration and a better prognosis. EBV infection status in gastric cancer is most commonly determined using PCR and in situ hybridization, but such a method requires good nucleic acid preservation. Detection of EBV status with histopathology images may complement PCR and in situ hybridization as a first step of EBV infection assessment. Here, we developed a deep learning-based algorithm to directly predict EBV infection …
