Nanostructured Fibers As A Versatile Photonic Platform: Radiative Cooling And Waveguiding Through Transverse Anderson Localization, Norman Nan Shi, Cheng-Chia Tsai, Michael J. Carter, Jyotirmoy Mandal, Adam C. Overvig, Matthew Y. Sfeir, Ming Lu, Catherine L. Craig, Gary D. Bernard, Yuan Yang, Nanfang Yu

Publications and Research

Broadband high reflectance in nature is often the result of randomly, three-dimensionally structured materials. This study explores unique optical properties associated with one-dimensional nanostructures discovered in silk cocoon fibers of the comet moth, Argema mittrei. The fibers are populated with a high density of air voids randomly distributed across the fiber cross-section but are invariant along the fiber. These filamentary air voids strongly scatter light in the solar spectrum. A single silk fiber measuring ~50 μm thick can reflect 66% of incoming solar radiation, and this, together with the fibers' high emissivity of 0.88 in the mid-infrared range, allows …

An Analysis Of Innovate Training With Bottlenose Dolphins (Tursiops Truncatus), Raymond John Van Steyn

Theses and Dissertations

The National Aquarium in Baltimore, Maryland conducted a training program in 2014 to develop a gestural command for their dolphins called “innovate”. This training paradigm was developed to resemble the seminal research by Pryor, Haag and O’Reilly (1969), as well as more recent efforts of Braslau-Schneck (1993) and Kuczaj and Eskelinen (2014) of training dolphins to offer “creative” behaviors not developed through conventional methods of behavioral modification, such as shaping. The goal of the present study was to observe records taken during the National Aquarium’s training procedure as well as data collected ~3 years after said training in order to …

Discriminating Radiation Injury From Recurrent Tumor With [18f]Parpi And Amino Acid Pet In Mouse Models, Patrick L. Donabedian, Susanne Kossatz, John A. Engelbach, Stephen A. Jannetti, Brandon Carney, Robert J. Young, Wolfgang A. Weber, Joel R. Garbow, Thomas Reiner

Publications and Research

Background

Radiation injury can be indistinguishable from recurrent tumor on standard imaging. Current protocols for this differential diagnosis require one or more follow-up imaging studies, long dynamic acquisitions, or complex image post-processing; despite much research, the inability to confidently distinguish between these two entities continues to pose a significant dilemma for the treating clinician. Using mouse models of both glioblastoma and radiation necrosis, we tested the potential of poly(ADP-ribose) polymerase (PARP)-targeted PET imaging with [¹⁸F]PARPi to better discriminate radiation injury from tumor.

Results

In mice with experimental radiation necrosis, lesion uptake on [¹⁸F]PARPi-PET was similar to …

Should Patients With Diabetes Be Encouraged To Integrate Social Media Into Their Care Plan?, Arun R. Nelakurthi, Angela Marinilli Pinto, Curtiss B. Cook, Lynne Jones, Mary Boyle, Jieping Ye, Theodoros Lappas, Jingrui He

Publications and Research

AIM: To evaluate the use of social media of individuals with diabetes mellitus (DM).

MATERIALS & METHODS: Both web-based and in-clinic surveys were collected from individuals with DM. Descriptive and correlation analyses were employed to evaluate respondents' diabetes-specific social networking site behaviors.

RESULTS: Forty-five patients with DM completed the web-based survey and 167, the clinic-based survey, of whom only 40 visited diabetes-specific social networking sites. Analysis of online survey data indicated that self-reported adherence to lifestyle recommendations was significantly correlated (p < 0.01) with visiting the sites. Clinic-based survey data found that patients who reported using DM-specific web sites monitored home glucose values more often and had better compliance with insulin administration (both p < 0.05) compared with nonusers.

CONCLUSION: This study provides insight into why individuals visit DM-specific social networking sites. Certain self-management behaviors may improve as …

Black Box, White Cube, Gray Zone: Dance Exhibitions And Audience Attention, Claire Bishop

Publications and Research

Relocated from the “black box” of experimental theatre to the “white cube” of the gallery, dance in the museum brings about new forms of performance — the dance exhibition — and new protocols of audience behavior that permit, even encourage, smartphone photography. This is the “gray zone” of recent performance, which is both a symptom of, and compensation for, the virtualization of contemporary perception.

Methods Matter: The Relationship Between Strength And Hypertrophy Depends On Methods Of Measurement And Analysis, Andrew D. Vigotsky, Brad J. Schoenfeld, Christian Than, J. Mark Brown

Publications and Research

Purpose: The relationship between changes in muscle size and strength may be affected by both measurement and statistical approaches, but their effects have not been fully considered or quantified. Therefore, the purpose of this investigation was to explore how different methods of measurement and analysis can affect inferences surrounding the relationship between hypertrophy and strength gain.

Methods: Data from a previous study—in which participants performed eight weeks of elbow flexor training, followed by an eight-week period of detraining—were reanalyzed using different statistical models, including standard between-subject correlations, analysis of covariance, and hierarchical linear modeling.

Results: The associative relationship between strength …

Spinal Control Of Locomotion: Individual Neurons, Their Circuits And Functions, Marie-Pascale Côté, Lynda M. Murray, Maria Knikou

Publications and Research

Systematic research on the physiological and anatomical characteristics of spinal cord interneurons along with their functional output has evolved for more than one century. Despite significant progress in our understanding of these networks and their role in generating and modulating movement, it has remained a challenge to elucidate the properties of the locomotor rhythm across species. Neurophysiological experimental evidence indicates similarities in the function of interneurons mediating afferent information regarding muscle stretch and loading, being affected by motor axon collaterals and those mediating presynaptic inhibition in animals and humans when their function is assessed at rest. However, significantly different muscle …

A Novel Multiscale Mathematical Model For Building Bone Substitute Materials For Children, Abdennasser Chekroun, Laurent Pujo-Menjouet, Jean-Philippe Berteau

Publications and Research

Bone is an engineering marvel that achieves a unique combination of stiffness and toughness exceeding that of synthesized materials. In orthopedics, we are currently challenged for the child population that needs a less stiff but a tougher bone substitute than adults. Recent evidence suggests that the relationship between inter-molecular connections that involve the two main bone building blocks, TropoCollagen molecules (TC) and carbonated Hydroxyapatite (cAp), and bone macroscopic mechanical properties, stiffness and toughness, are key to building bone substitute materials for children. The goal of our study is to establish how inter-molecular connections that occur during bone mineralization are related …

Anchored Phylogenomics Illuminates The Skipper Butterfly Tree Of Life, Emmanuel F. A. Toussaint, Jesse W. Breinholt, Chandra Earl, Andrew D. Warren, Andrew V. Z. Brower, Masaya Yago, Kelly M. Dexter, Marianne Espeland, Naomi E. Pierce, David J. Lohman, Akito Y. Kawahara

Publications and Research

Background: Butterflies (Papilionoidea) are perhaps the most charismatic insect lineage, yet phylogenetic relationships among them remain incompletely studied and controversial. This is especially true for skippers (Hesperiidae), one of the most species-rich and poorly studied butterfly families.

Methods: To infer a robust phylogenomic hypothesis for Hesperiidae, we sequenced nearly 400 loci using Anchored Hybrid Enrichment and sampled all tribes and more than 120 genera of skippers. Molecular datasets were analyzed using maximum-likelihood, parsimony and coalescent multi-species phylogenetic methods.

Results: All analyses converged on a novel, robust phylogenetic hypothesis for skippers. Different optimality criteria and methodologies recovered almost …

Direct Current Stimulation Of Endothelial Monolayers Induces A Transient And Reversible Increase In Transport Due To The Electroosmotic Effect, Limary M. Cancel, Katherin Arias, Marom Bikson, John M. Tarbell

Publications and Research

We investigated the effects of direct current stimulation (DCS) on fluid and solute transport across endothelial cell (EC) monolayers in vitro. Our motivation was transcranial direct current stimulation (tDCS) that has been investigated for treatment of neuropsychiatric disorders, to enhance neurorehabilitation, and to change cognition in healthy subjects. The mechanisms underlying this diversity of applications remain under investigation. To address the possible role of blood-brain barrier (BBB) changes during tDCS, we applied direct current to cultured EC monolayers in a specially designed chamber that generated spatially uniform direct current. DCS induced fluid and solute movement across EC layers that persisted …

The Problem Of Sexual Harassment, Aldemaro Romero Jr.

Publications and Research

In the last few months, the media have been inundated with news about sexual harassment of women. The cases with the most notoriety have been those of celebrities or associated with the entertaining industry, but they have not been the only ones. This attention to the issue has generated what is called the “Me Too Movement” (or “MeToo”). With sexual harassment and assault occurring in every segment of society, it is important to ask how this issue is seen on college campuses, which have been accused of too much “political correctness” in the past.

A new study published last week …

Developing research questions and formulating thesis statements are among the most challenging duties of a young researcher. From high school through undergraduate, students often have minimal experience conducting research. They may not know where to begin the research process and what steps are necessary. Student frustration is exacerbated …

Carbonic Anhydrase Inhibition Selectively Prevents Amyloid B Neurovascular Mitochondrial Toxicity, María E. Solesio, Pablo M. Peixoto, Ludovic Debure, Stephen M. Madamba, Mony J. De Leon, Thomas Wisniewski, Evgeny V. Pavlov, Silvia Fossati

Publications and Research

Mounting evidence suggests that mitochondrial dysfunction plays a causal role in the etiology and progression of Alzheimer’s disease (AD). We recently showed that the carbonic anhydrase inhibitor (CAI) methazolamide (MTZ) prevents amyloid b (Ab)-mediated onset of apoptosis in the mouse brain. In this study, we used MTZ and, for the first time, the analog CAI acetazolamide (ATZ) in neuronal and cerebral vascular cells challenged with Ab, to clarify their protective effects and mitochondrial molecular mechanism of action. The CAIs selectively inhibited mitochondrial dysfunction pathways induced by Ab, without affecting metabolic function. ATZ was effective at concentrations 10 times lower than …

Student Theses

An enzymatic method to process decomposed non-human bone for forensic DNA analysis is presented. Red snapper species is identified by sequencing of the COI gene.

Forensic analysis of DNA from non-human bones can be important in investigating a variety of forensic cases. However, decomposed bone is difficult to process for isolating DNA. In this study, a previously established enzymatic method was utilized to process bone samples that simulate decomposed specimens. Our results demonstrated that this enzymatic processing method is effective for removing decomposed soft tissues and outer surface materials such as mineralized bone connective tissue of bone fragment samples. Our …

Imagination Or Proof: The Use Of Imagery And False Evidence In Eliciting Internalized False Confessions, Kendall Mcmillen

Student Theses

Rates of internalized false confessions has become increasingly salient through the use of DNA evidence in exonerating those who have been wrongfully convicted. False confessions also carry heavy legal consequences, and internalized false confessions (Appleby & Kassin, 2016; Kassin & Neumann, 1997; Kassin & Wrightsman, 1980), where the individual actually believes they committed a crime, may be especially damning (Kassin S., 2007). The presentation of false evidence has been found to be extremely influential in eliciting a false confession (Horselenberg, Merckelbach, & Josephs, 2003; Kassin & Kiechel, 1996; Nash & Wade, 2009), as well as imagery (Garry, Manning, Loftus, & …

Investigating The Effects Of Trans-Spinal Direct Current Stimulation On The Expression Of Nkcc1 In Mice, Pasindu Weliwaththage

Student Theses

Trans-spinal direct current stimulation (tsDCS) is a non-invasive powerful tool demonstrated to positively affect behavior and motor function. tsDCS is a neuromodulatory technique capable of altering spinal and cortical excitability and even regain motor function after complete motor paralysis (Cortes et at, 2017). tsDCS causes immediate and long-term effects in spinal excitability (Ahmed, 2011, 2013; Ahmed and Wieraszko, 2012; Cogiamanian et al., 2011, 2012). Studies have been conducted on both healthy and injured subjects. The ultimate goal is to ameliorate the devastating effects of Spinal Cord Injury. Though researchers have been successful in improving motor function, the molecular basis of …

Murmur/Murmuro, Paola M. Di Tolla

Theses and Dissertations

By using repetition or misplacing intonations and accents, etc. one can imitate the slipperiness of spoken language. However, it is the accidental slippage that I find most revealing and exciting because it allows for two conversations to exist in one. Once spoken language is transcribed as text, it is put through another filter and the risk of [accidental] slippage increases by a different measure. Fingers don’t keep up or autocorrect insists on taking matters into its own hands.

Maternal Betaine Supplementation Affects Fetal Growth And Lipid Metabolism Of Highfat Fed Mice In A Temporal-Specific Manner, Yaelle Joselit, Khatia Nanobashvili, Chauntelle Jack-Roberts, Esther Greenwald, Olga V. Malysheva, Marie A. Caudill, Anjana Saxena, Xinyin Jang

Publications and Research

Background/objectives: Maternal obesity increases the risk of gestational diabetes mellitus (GDM), which results in fetal overgrowth and long-lasting metabolic dysfunctioning in the offspring. Previous studies show that maternal choline supplementation normalizes fetal growth and adiposity of progeny from obese mice. This study examines whether supplementation of betaine, a choline derivative, has positive effects on fetal metabolic outcomes in mouse progeny exposed to maternal obesity and GDM.

Methods: C57BL/6J mice were fed either a high-fat (HF) diet or a control (normal-fat, NF) diet and received either 1% betaine (BS) or control untreated (BC) drinking water 4–6 weeks before timed-mating and throughout …

Perinatal Pb2+ Exposure Alters The Expression Of Genes Related To The Neurodevelopmental Gaba-Shift In Postnatal Rats, Lorenz Simon Neuwirth, Greg R. Phillips, Abdeslem El Idrissi

Publications and Research

Background: Lead (Pb2+) is an environmental neurotoxicant that disrupts neurodevelopment, communication, and organization through competition with Ca2+ signaling. How perinatal Pb2+ exposure affects Ca2+-related gene regulation remains unclear. However, Ca2+ activates the L-Type voltage sensitive calcium channel β-3 subunit (Ca-β3), which autoregulates neuronal excitability and plays a role in the GABA-shift from excitatory-toinhibitory neurotransmission.

Method: A total of eight females (n = 4 Control and n = 4 Perinatal) and four males (n = 2 Control and n = 2 Perinatal) rats were used as breeders to serve as Dams and Sires. The Dam’s litters each ranged from N = …
