Aerosol Gemcitabine After Amputation Inhibits Osteosarcoma Lung Metastases But Not Wound Healing, Eugenie S. Kleinerman, Ling Yu, Jasmine Dao, Andrea A. Hayes-Jordan, Brock Lindsey, Jitesh D. Kawedia, John Stewart, Nancy Gordon

Clinical and Translational Science Institute

Background. In newly diagnosed osteosarcoma (OS) patients, the time between surgery and resumption of chemotherapy is 2–7 weeks. Delays > 16 days are associated with increased risk of relapse and decreased overall survival. Identifying an e4ective therapy that can be used postoperatively may prevent relapse. We investigated whether aerosol gemcitabine (GCB) initiated after tumor resection inhibited the growth of OS lung metastases without a4ecting the wound-healing process. Methods. Mice were injected intratibially with OS cells. Amputation was performed when the tumor reached 1.5 cm. Fullthickness excisional wounds were also made on the dorsal skin and tail. Aerosol GCB or PBS was …

Absolute Lymphocyte And Neutrophil Counts In Neonatal Ischemic Brain Injury, J M. Povroznik, E B. Engler-Chiurazzi, T Nanavati, P Pergami

Clinical and Translational Science Institute

Objectives: This study aimed to identify differences in absolute neutrophils, lymphocytes, and neutrophil-to-lymphocyte ratio between neonates with two forms of ischemic brain injury, hypoxic-ischemic encephalopathy, and acute ischemic stroke, compared to controls. We also aimed to determine whether this neutrophil/lymphocyte response pattern is associated with disease severity or is a consequence of the effects of total-body cooling, an approved treatment for moderate-to-severe hypoxic-ischemic encephalopathy. Methods: A retrospective chart review of 101 neonates with hypoxic-ischemic encephalopathy+total-body cooling (n=26), hypoxic-ischemic encephalopathy (n=12), acute ischemic stroke (n=15), and transient tachypnea of the newborn (n=48) was conducted; transient tachypnea of the newborn neonates were …

Liposomal Irinotecan Accumulates In Metastatic Lesions, Crosses The Blood-Tumor Barrier (Btb), And Prolongs Survival In An Experimental Model Of Brain Metastases Of Triple Negative Breast Cancer, Afroz S. Mohammad, Jessica I. Griffith, Chris E. Adkins, Neal Shah, Emily Sechrest, Emma L. Dolan, Tori B. Terrell-Hall, Bart S. Hendriks, Helen Lee, Paul R. Lockman

Clinical and Translational Science Institute

Purpose—The blood-tumor barrier (BTB) limits irinotecan distribution in tumors of the central nervous system. However, given that the BTB has increased passive permeability we hypothesize that liposomal irinotecan would improve local exposure of irinotecan and its active metabolite SN-38 in brain metastases relative to conventional irinotecan due to enhanced-permeation and retention (EPR) effect. Methods—Female nude mice were intracardially or intracranially implanted with human brain seeking breast cancer cells (brain metastases of breast cancer model). Mice were administered vehicle, non-liposomal irinotecan (50 mg/kg), liposomal irinotecan (10 mg/kg and 50 mg/kg) intravenously starting on day 21. Drug accumulation, tumor burden, and survival …

Genomic Analysis Of Demographic History And Ecological Niche Modeling In The Endangered Sumatran Rhinoceros Dicerorhinus Sumatrensis, Herman L. Mays Jr., Chih-Ming Hung, Pei-Jen Shaner, James Denvir, Megan Justice, Shang-Fang Yang, Terri L. Roth, David A. Oheler, Jun Fan, Swanthana Rekulapally, Donald A. Primerano

Clinical and Translational Science Institute

The vertebrate extinction rate over the past century is approximately 22 – 100 times greater than background extinction rates [1] and large mammals are particularly at risk [2, 3]. Quaternary megafaunal extinctions have been attributed to climate change [4], overexploitation [5] or a combination of the two [6]. Rhinoceroses (Family: Rhinocerotidae) have a rich fossil history replete with iconic examples of climate-induced extinctions [7], but current pressures threaten to eliminate this group entirely. The Sumatran Rhinoceros (Dicerorhinus sumatrensis) is among the most imperiled mammals on earth. The 2011 population was estimated at ≤ 216 wild individuals [8] and currently the …

Crosstalk Among Lncrnas, Micrornas And Mrnas In The Muscle ‘Degradome’ Of Rainbow Trout, Bam Paneru, Ali Ali, Rafet Al-Tobasei, Brett Kenney, Mohamed Salem

Faculty & Staff Scholarship

In fish, protein-coding and noncoding genes involved in muscle atrophy are not fully characterized. In this study, we characterized coding and noncoding genes involved in gonadogenesis-associated muscle atrophy, and investigated the potential functional interplay between these genes. Using RNA- Seq, we compared expression pattern of mRNAs, long noncoding RNAs (lncRNAs) and microRNAs of atrophying skeletal muscle from gravid females and control skeletal muscle from age-matched sterile individuals. A total of 852 mRNAs, 1,160 lncRNAs and 28 microRNAs were differentially expressed (DE) between the two groups. Muscle atrophy appears to be mediated by many genes encoding ubiquitin- proteasome system, autophagy related …

Reduction Of Endothelial Nitric Oxide Increases The Adhesiveness Of Constitutive Endothelial Membrane Icam-1 Through Src-Mediated Phosphorylation, Feng Gao, Brandon P. Lucke-Wold, Xiang Li, Aric F. Logsdon, Li-Chong Xu, Sulei Xu, Kyle B. Lapenna, Huaqi Wang, M.A. Hassan Talukder, Christopher A. Siedlecki, Jason D. Huber, Charles L. Rosen, Pingnian He

Nitric oxide (NO) is a known anti-adhesive molecule that prevents platelet aggregation and leukocyte adhesion to endothelial cells (ECs). The mechanism has been attributed to its role in the regulation of adhesion molecules on leukocytes and the adhesive properties of platelets. Our previous study conducted in rat venules found that reduction of EC basal NO synthesis caused EC ICAM-1-mediated firm adhesion of leukocytes within 10–30min. This quick response occurred in the absence of alterations of adhesion molecules on leukocytes and also opposes the classical pattern of ICAM-1-mediated leukocyte adhesion that requires protein synthesis and occurs hours after stimulation. The objective …

Bordetella Pertussis Whole Cell Immunization, Unlike Acellular Immunization, Mimics Naïve Infection By Driving Hematopoietic Stem And Progenitor Cell Expansion In Mice, Melinda E. Varney, Dylan T.

Hematopoietic stem and progenitor cell (HSPC) compartments are altered to direct immune responses to infection. Their roles during immunization are not well-described. To elucidate mechanisms for waning immunity following immunization with acellular vaccines (ACVs) against Bordetella pertussis (Bp), we tested the hypothesis that immunization with Bp ACVs and whole cell vaccines (WCVs) differ in directing the HSPC characteristics and immune cell development patterns that ultimately contribute to the types and quantities of cells produced to fight infection. Our data demonstrate that compared to control and ACV-immunized CD-1 mice, immunization with an efficacious WCV drives expansion of hematopoietic multipotent progenitor cells …

Navigating The "No Man's Land" Of Tki-Failed Egfr-Mutated Non-Small Cell Lung Cancer (Nsclc): A Review, Bryan Oronsky, Patrick Ma, Tony R. Reid, Pedro Cabrales, Michelle Lybeck, Arnold Oronsky, Neil Oronsky, Corey A. Carter

Clinical and Translational Science Institute

As the leading cause of cancer-related mortality, lung cancer is a worldwide health issue that is overwhelmingly caused by smoking. However, a substantial minority (~25%) of patients with non–small cell lung cancer (NSCLC) has never smoked. In these patients, activating mutations of the epidermal growth factor receptor (EGFR) are more likely, which render their tumors susceptible for a finite period to treatment with EGFR tyrosine kinase inhibitors (TKIs) and confer a better prognosis than EGFR wild-type NSCLC. On progression, due to the inevitable insurgence of resistance, TKIs are generally followed by second- or third-line salvage chemotherapy until treatment failure, after …

The Endogenous Cannabinoid System: A Budding Source Of Targets For Treating Inflammatory And Neuropathic Pain, Giulia Donvito, Sara R. Nass, Jenny L. Wilkerson, Zachary A. Curry, Lesley D. Schurman, Steven G. Kinsey, Aron H. Lichtman

Clinical and Translational Science Institute

A great need exists for the development of new medications to treat pain resulting from various disease states and types of injury. Given that the endogenous cannabinoid (that is, endocannabinoid) system modulates neuronal and immune cell function, both of which play key roles in pain, therapeutics targeting this system hold promise as novel analgesics. Potential therapeutic targets include the cannabinoid receptors, type 1 and 2, as well as biosynthetic and catabolic enzymes of the endocannabinoids N-arachidonoylethanolamine and 2-arachidonoylglycerol. Notably, cannabinoid receptor agonists as well as inhibitors of endocannabinoid-regulating enzymes fatty acid amide hydrolase and monoacylglycerol lipase produce reliable antinociceptive effects, …

Bacteria Antibiotic Resistance: New Challenges And Opportunities For Implant-Associated Orthopedic Infections, Bingyun Li, Thomas J. Webster

Clinical and Translational Science Institute

There has been a dramatic increase in the emergence of antibiotic resistant bacterial strains, which has made antibiotic choices for infection control increasingly limited and more expensive. In the U.S. alone, antibiotic resistant bacteria cause at least 2 million infections and 23,000 deaths a year resulting in a $55–70 billion per year economic impact. Antibiotics are critical to the success of surgical procedures including orthopaedic prosthetic surgeries, and antibiotic resistance is occurring in nearly all bacteria that infect people, including the most common bacteria that cause orthopaedic infections, such as Staphylococcus aureus (S. aureus). Most clinical cases of orthopaedic surgeries …

Association Of The Severity Of Diabetes- Related Complications With Stage Of Breast Cancer At Diagnosis Among Elderly Women With Pre-Existing Diabetes, Ebtihag O. Alenzi, S. Suresh Madhavan, Xi Tan

Clinical and Translational Science Institute

Purpose—This study assessed the association between the severity of diabetes complications using diabetes complications severity index (DCSI) and stage of breast cancer (BC) at diagnosis among elderly women with pre-existing diabetes and incident BC. Methods—Using Surveillance, Epidemiology and End Results-Medicare data, we identified women with incident BC during 2004–2011 and pre-existing diabetes (N = 7729). Chi-square tests were used to test for group differences in stage of BC at diagnosis. Multinomial logistic regression was used to examine the associations between the severity of diabetes complications and stage of BC at diagnosis. Results—Overall, women with a DCSI = 2 and a …

Objective: Family meals, particularly those occurring in calm environments, are associated with numerous health benefits for both children and parents. However, families often struggle to share meals, with the frequency declining as kids get older. This qualitative research study aimed to explore the factors influencing family meal behaviors.

Methods: Parents (n=38) and school-age children (n=37) participated in focus group discussions guided by Social Cognitive Theory.

Results: Content analysis results indicate that parents and children believed family meals were important, promoted communication, and strengthened family bonds. Parents and children reported that a calm, enjoyable, conflict-free mealtime environment bolstered mealtime enjoyment and …

Conjugative Transposons And Their Cargo Genes Vary Across Natural Populations Of Rickettsia Buchneri Infecting The Tick Ixodes Scapularis, Rachael Hagen, Victoria I. Verhoeve, Joseph J. Gillespie, Timothy P. Driscoll

Faculty & Staff Scholarship

Rickettsia buchneri (formerly Rickettsia endosymbiont of Ixodes scapularis, or REIS) is an obligate intracellular endoparasite of the black-legged tick, the primary vector of Lyme disease in North America. It is noteworthy among the rickettsiae for its relatively large genome (1.8 Mb) and extraordinary proliferation of mobile genetic elements (MGEs), which comprise nearly 35% of its genome. Previous analysis of the R. buchneri genome identified several integrative conjugative elements named Rickettsiales amplified genomic elements (RAGEs); the composition of these RAGEs suggests that continued genomic invasions by MGEs facilitated the proliferation of rickettsial genes related to an intracellular lifestyle. In this study, …

Low Sucrose, Omega-3 Enriched Diet Has Region-Specific Effects On Neuroinflammation And Synaptic Function Markers In A Mouse Model Of Doxorubicin-Based Chemotherapy, Tonya S. Orchard, Monica M.

Faculty & Staff Scholarship

Chemotherapeutic agents such as doxorubicin may negatively affect long-term brain functioning in cancer survivors; neuroinflammation may play a causal role. Dietary approaches that reduce inflammation, such as lowering sucrose and increasing eicosapentaenoic acid plus docosahexaenoic acid (EPA + DHA), may attenuate chemotherapy-induced neuroinflammation and synaptic damage, thereby improving quality of life. Ovariectomized, C57BL/6 mice were assigned to a chemotherapy (9 mg/kg doxorubicin + 90 mg/kg cyclophosphamide) or vehicle two-injection regimen, with injections two and four weeks after starting diets. In Study 1, mice received low sucrose diets with EPA + DHA or No EPA + DHA for four to six …

Approaches To Denoise The Diffuse Optical Signals For Tissue Blood Flow Measurement, Peng Zhang, Zhiguo Gui, Yu Shang

Faculty & Staff Scholarship

Various diseases are relevant to the abnormal blood flow in tissue. Diffuse correlation spectroscopy (DCS) is an emerging technology to extract the blood flow index (BFI) from light electric field temporal autocorrelation data. To account for tissue heterogeneity and irregular geometry, we developed an innovative DCS algorithm (i.e., the Nth order linear algorithm, or simply the NL algorithm) previously, in which the DCS signals are fully utilized through iterative linear regressions. Under the framework of NL algorithm, the BFI to be extracted is significantly influenced by the linear regression approach adopted. In this study, three approaches were proposed and evaluated …

A Novel Method For Training Mice In Visuo-Tactile 3-D Object Discrimination And Recognition, Xian Hu, Ogaga Urhie, Kevin Chang, Rachel Hostetler, Ariel Agmon

Faculty & Staff Scholarship

Perceiving, recognizing and remembering 3-dimensional (3-D) objects encountered in the environment has a very high survival value; unsurprisingly, this ability is shared among many animal species, including humans. The psychological, psychophysical and neural basis for object perception, discrimination, recognition and memory has been extensively studied in humans, monkeys, pigeons and rodents, but is still far from understood. Nearly all 3-D object recognition studies in the rodent used the “novel object recognition” paradigm, which relies on innate rather than learned behavior; however, this procedure has several important limitations. Recently, investigators have begun to recognize the power of behavioral tasks learned through …

Faculty & Staff Scholarship

Background: The cardiovascular effects of pulmonary exposure to engineered nanomaterials (ENM) are poorly understood, and the reproductive consequences are even less understood. Inflammation remains the most frequently explored mechanism of ENM toxicity. However, the key mediators and steps between lung exposure and uterine health remain to be fully defined. The purpose of this study was to determine the uterine inflammatory and vascular effects of pulmonary exposure to titanium dioxide nanoparticles (nano-TiO2). We hypothesized that pulmonary nano-TiO2 exposure initiates a Th2 inflammatory response mediated by Group II innate lymphoid cells (ILC2), which may be associated with an impairment in uterine microvascular …

Adp-Ribosylation Factor-Like 2 (Arl2) Regulates Cilia Stability And Development Of Outer Segments In Rod Photoreceptor Neurons, Zachary C. Wright, Yuriy Loskutov, Daniel Murphy, Peter Stoilov, Elena Pugacheva, Andrew F.X. Goldberg, Visvanathan Ramamurthy

Faculty & Staff Scholarship

Photoreceptor cells are specialized neurons with a sensory cilium carrying an elaborate membrane structure, the outer segment (OS). Inherited mutations in genes involved in ciliogenesis frequently result in OS malformation and blindness. ADP-ribosylation factor-like 2 (ARL2) has recently been implicated in OS formation through its association with Binder of ARL2 (BART or ARL2BP), a protein linked to inherited blinding disease. To test the role of ARL2 in vision we created a transgenic mouse model expressing a tagged-dominant active form of human ARL2 (ARL2-Q70L) under a rod-specific promoter. Transgenic ARL2-Q70L animals exhibit reduced photoreceptor cell function as early as post-natal day …

Analytical Cpg Model Driven By Limb Velocity Input Generates Accurate Temporal Locomotor Dynamics, Sergiy Yakovenko, Anton Sobinov, Valeriya Gritsenko

Faculty & Staff Scholarship

The ability of vertebrates to generate rhythm within their spinal neural networks is essential for walking, running, and other rhythmic behaviors. The central pattern generator (CPG) network responsible for these behaviors is well-characterized with experimental and theoretical studies, and it can be formulated as a nonlinear dynam- ical system. The underlying mechanism responsible for locomotor behavior can be expressed as the process of leaky integration with resetting states generating appropriate phases for changing body velocity. The low-dimensional input to the CPG model generates the bilateral pattern of swing and stance modulation for each limb and is consistent with the desired …

Direct or indirect exposure to an explosion can induce traumatic brain injury (TBI) of various severity levels. Primary TBI from blast exposure is commonly characterized by internal injuries, such as vascular damage, neuronal injury, and contusion, without external injuries. Current animal models of blast-induced TBI (bTBI) have helped to understand the deleterious effects of moderate to severe blast forces. However, the neurological effects of mild blast forces remain poorly characterized. Here, we investigated the effects caused by mild blast forces combining neuropathological, histological, biochemical and neurophysiological analysis. For this purpose, we employed a rodent blast TBI model with blast forces …

Embodying Functionally Relevant Action Sounds In Patients With Spinal Cord Injury, Mariella Pazzaglia, Giulia Galli, James W. Lewis, Giorgio Scivoletto, Anna Maria Giannini, Marco Molinari

Faculty & Staff Scholarship

Growing evidence indicates that perceptual-motor codes may be associated with and influenced by actual bodily states. Following a spinal cord injury (SCI), for example, individuals exhibit reduced visual sensitivity to biological motion. However, a dearth of direct evidence exists about whether profound alterations in sensorimotor traffic between the body and brain influence audio-motor representations. We tested 20 wheelchair-bound individuals with lower skeletal-level SCI who were unable to feel and move their lower limbs, but have retained upper limb function. In a two-choice, matching-to-sample auditory discrimination task, the participants were asked to determine which of two action sounds matched a sample …

Multiple regression models examined associations between FCP and log-transformed dietary intake, controlling for sex, age, race, and BMI. Participant …

Systematic Analysis Of Transmitter Coexpression Reveals Organizing Principles Of Local Interneuron Heterogeneity, Kristyn M. Lizbinski, Gary Marsat, Andrew M. Dacks

Faculty & Staff Scholarship

Broad neuronal classes are surprisingly heterogeneous across many parameters, and subclasses often exhibit partially overlapping traits including transmitter coexpression. However, the extent to which transmitter coex- pression occurs in predictable, consistent patterns is unknown. Here, we demonstrate that pairwise coexpression of GABA and multiple neuropeptide families by olfactory local interneurons (LNs) of the moth Manduca sexta is highly heterogeneous, with a single LN capable of expressing neuropeptides from at least four peptide families and few instances in which neuropeptides are consistently coexpressed. Using computational modeling, we demonstrate that observed coexpression patterns cannot be explained by independent probabilities of expres- sion …

Genome-Wide Association Analysis With A 50k Transcribed Gene Snp-Chip Identifies Qtl Affecting Muscle Yield In Rainbow Trout, Mohamed Salem, Rafet Al-Tobasei, Ali Ali, Daniela Lourenco, Guangtu Gao, Yniv Palti, Brett Kenney, Timothy D. Leeds

Faculty & Staff Scholarship

Detection of coding/functional SNPs that change the biological function of a gene may lead to identification of putative causative alleles within QTL regions and discovery of genetic markers with large effects on phenotypes. This study has two-fold objectives, first to develop, and validate a 50K transcribed gene SNP-chip using RNA-Seq data. To achieve this objective, two bioinformatics pipelines, GATK and SAMtools, were used to identify ∼21K transcribed SNPs with allelic imbalances associated with important aquaculture production traits including body weight, muscle yield, muscle fat content, shear force, and whiteness in addition to resistance/susceptibility to bacterial cold-water disease (BCWD). SNPs ere …

Sugar-sweetened beverages (SSBs) are a leading source of added sugar in the American diet. Further, ingestion of added sugars from SSBs exceeds recommendations. Thus, interventions that effectively reduce SSB consumption are needed. Focus group discussions with parents (n = 37) and school-aged children between the ages of 6 and 11 years (n = 41) from Florida, New Jersey, and West Virginia were led by trained moderators using Social Cognitive Theory as a guide. Trends and themes that emerged from the content analysis of the focus group data indicated that both parents and children felt that limiting SSBs was important to …

Detecting Body Mass Index From A Facial Photograph In Lifestyle Intervention, Makenzie L. Barr, Guodong Guo, Sarah E. Colby, Melissa D. Olfert

Faculty & Staff Scholarship

This study aimed to identify whether a research participant’s body-mass index (BMI) can be correctly identified from their facial image (photograph) in order to improve data capturing in dissemination and implementation research. Facial BMI (fBMI) was measured using an algorithm formulated to identify points on each enrolled participant’s face from a photograph. Once facial landmarks were detected, distances and ratios between them were computed to characterize facial fatness. A regression function was then used to represent the relationship between facial measures and BMI values to then calculate fBMI from each photo image. Simultaneously, BMI was physically measured (mBMI) by trained …
