Egg Discrimination Along A Gradient Of Natural Variation In Eggshell Coloration, Daniel Hanley, Tomáš Grim, Branislav Igic, Peter Samaš, Analía V. López, Matthew D. Shawkey, Mark E. Hauber

Publications and Research

Accurate recognition of salient cues is critical for adaptive responses, but the underlying sensory and cognitive processes are often poorly understood. For example, hosts of avian brood parasites have long been assumed to reject foreign eggs from their nests based on the total degree of dissimilarity in colour to their own eggs, regardless of the foreign eggs’ colours. We tested hosts’ responses to gradients of natural (blue-green to brown) and artificial (green to purple) egg colours, and demonstrate that hosts base rejection decisions on both the direction and degree of colour dissimilarity along the natural, but not artificial, gradient of …

Identification Of A Vacuolar Proton Channel That Triggers The Bioluminescent Flash In Dinoflagellates, Juan D. Rodriguez, Saddef Haq, Tsvetan Bachvaroff, Kristine F. Nowak, Scott J. Nowak, Deri Morgan, Vladimir V. Cherny, Maredith M. Sapp, Steven Bernstein, Andrew Bolt, Thomas E. Decoursey, Allen R. Place, Susan M. Smith

Faculty Articles

In 1972, J. Woodland Hastings and colleagues predicted the existence of a proton selective channel (HV1) that opens in response to depolarizing voltage across the vacuole membrane of bioluminescent dinoflagellates and conducts protons into specialized luminescence compartments (scintillons), thereby causing a pH drop that triggers light emission. HV1 channels were subsequently identified and demonstrated to have important functions in a multitude of eukaryotic cells. Here we report a predicted protein from Lingulodinium polyedrum that displays hallmark properties of bona fide HV1, including time-dependent opening with depolarization, perfect proton selectivity, and characteristic ΔpH dependent gating. Western blotting and fluorescence confocal microscopy …

Immune Responses In Hibernating Little Brown Myotis (Myotis Lucifugus) With White-Nose Syndrome, Thomas M. Lilley, Jenni M. Prokkola, Elisabeth Jeanine Rogers, Sarah Gronsky, Allen Kurta, Deeann Reeder, Kenneth A. Field

Faculty Journal Articles

White-nose syndrome (WNS) is a fungal disease responsible for decimating many bat populations in North America. Pseudogymnoascus destructans (Pd), the psychrophilic fungus responsible for WNS, prospers in the winter habitat of many hibernating bat species. The immune response that Pd elicits in bats is not yet fully understood; antibodies are produced in response to infection by Pd, but they may not be protective and indeed may be harmful. To understand how bats respond to infection during hibernation, we studied the effect of Pd inoculation on the survival and gene expression of captive hibernating Myotis lucifugus with varying …

Intestinal Microbiota And Weight-Gain In Preterm Neonates, Silvia Arboleya, Pablo Martinez-Camblor, Gonzalo Solís, Marta Suárez

Dartmouth Scholarship

The involvement of the gut microbiota on weight-gain and its relationship with childhood undernutrition and growth has been reported. Thus, the gut microbiota constitutes a potential therapeutic target for preventing growth impairment. However, our knowledge in this area is limited. In this study we aimed at evaluating the relationship among early microbiota, growth, and development in preterm infants. To this end we assessed the levels of specific microorganisms by qPCR, and those of short chain fatty acids by mean of gas-chromatography, in feces from 63 preterm newborns and determined their weight-gain during the first months. The statistical analyses performed indicate …

Shifts In Biomass And Productivity For A Subtropical Dry Forest In Response To Simulated Elevated Hurricane Disturbances, Jennifer A. Holm, Skip J. Van Bloem, Guy R. Larocque, Herman H. Shugart

Publications

Caribbean tropical forests are subject to hurricane disturbances of great variability. In addition to natural storm incongruity, climate change can alter storm formation, duration, frequency, and intensity. This model-based investigation assessed the impacts of multiple storms of different intensities and occurrence frequencies on the long-term dynamics of subtropical dry forests in Puerto Rico. Using the previously validated individual-based gap model ZELIG-TROP, we developed a new hurricane damage routine and parameterized it with site- and species-specific hurricane effects. A baseline case with the reconstructed historical hurricane regime represented the control condition. Ten treatment cases, reflecting plausible shifts in hurricane regimes, manipulated …

The Effects Of Camelina Sativa Meal On Haemonchus Contortus In Breeding Age Ewes, Nicole Julia Nichols

Student Theses and Dissertations

Gastrointestinal parasites (GIP) are one of the greatest threats to sheep production in the United States. Increased resistance to traditional anthelmintics has created the need for alternative methods to control GIP. The objective of this study was to determine if Camelina sativa (CS) meal could be fed as part of a daily ration to reduce infection rates of the GIP Haemonchus contortus during two 28-day trials. Forty-eight ewes were sorted and fed a 14% crude protein (CP) supplement with or without 10% CS as part of their daily ration. All ewes grazed a mixture of Bermuda (Cynodon dactylon) and tall …

Resistance Monitoring Of Oebalus Pugnax F., Rice Stink Bug, Against Select Insecticides, Audra Lee Cross

Student Theses and Dissertations

Rice stink bug, Oebalus pugnax F. is a pest of rice that impacts quality of grain. Pyrethroid insecticides are the main control method. However, there is concern that pyrethroid insecticides are not providing adequate control, due to development of insecticide resistance. With this in mind, efforts were focused on monitoring rice stink bug resistance to λ-cyhalothrin, a common pyrethroid, and obtaining baseline data for a new chemistry of insecticides, a neonicotinoid (dinotefuran), for rice stink bug. For the purposes of the research presented here the adult vial test was used for monitoring λ-cyhalothrin resistance and a modified adult vial test …

Measurements And Models Of Electric Fields In The In Vivo Human Brain During Transcranial Electric Stimulation, Yu Huang, Anli A. Liu, Belen Lafon, Daniel Friedman, Michael Dayan, Xiuyuan Wang, Marom Bikson, Werner K. Doyle, Orrin Devinsky, Lucas C. Parra

Publications and Research

Transcranial electric stimulation aims to stimulate the brain by applying weak electrical currents at the scalp. However, the magnitude and spatial distribution of electric fields in the human brain are unknown. We measured electric potentials intracranially in ten epilepsy patients and estimated electric fields across the entire brain by leveraging calibrated current-flow models. When stimulating at 2 mA, cortical electric fields reach 0.8 V/m, the lower limit of effectiveness in animal studies. When individual whole-head anatomy is considered, the predicted electric field magnitudes correlate with the recorded values in cortical (r = 0.86) and depth (r = 0.88) electrodes. Accurate …

Editing Of Misaminoacylated Trna Controls The Sensitivity Of Amino Acid Stress Responses In Saccharomyces Cerevisiae, Kyle Mohler, Rebecca Mann, Tammy J. Bullwinkle, Kyle W. Hopkins, Lin Hwang, Noah M. Reynolds, Brandon Gassaway, Hans-Rudolph Aerni, Jesse Rinehart, Michael Polymenis, Kym F. Faull, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Amino acid starvation activates the protein kinase Gcn2p, leading to changes in gene expression and translation. Gcn2p is activated by deacylated tRNA, which accumulates when tRNA aminoacylation is limited by lack of substrates or inhibition of synthesis. Pairing of amino acids and deacylated tRNAs is catalyzed by aminoacyl-tRNA synthetases, which use quality control pathways to maintain substrate specificity. Phenylalanyl-tRNA synthetase (PheRS) maintains specificity via an editing pathway that targets non-cognate Tyr-tRNA^Phe. While the primary role of aaRS editing is to prevent misaminoacylation, we demonstrate editing of misaminoacylated tRNA is also required for detection of amino acid starvation by …

Metastatic Biomarkers In Synovial Sarcoma, Rosalia De Necochea-Campion, Lee M. Zuckerman, Hamid R. Mirshahidi, Shahrzad Khosrowpour, Chien-Shing Chen, Saied Mirshahidi

Library Articles and Research

Synovial sarcoma (SS) is an aggressive soft tissue sarcoma (STS) that typically occurs in the extremities near a joint. Metastatic disease is common and usually occurs in the lungs and lymph nodes. Surgical management is the mainstay of treatment with chemotherapy and radiation typically used as adjuvant treatment. Although chemotherapy has a positive impact on survival, the prognosis is poor if metastatic disease occurs. The biology of sarcoma invasion and metastasis remain poorly understood. Chromosomal translocation with fusion of the SYT and SSX genes has been described and is currently used as a diagnostic marker, although the full impact of …

A Novel Microrna-1207-3p/Fndc1/Fn1/Ar Regulatory Pathway In Prostate Cancer, Dibash K. Das, Olorunseun O. Ogunwobi

Publications and Research

Prostate cancer (PCa) is the second most common cause of cancer-specific deaths in the U.S. Unfortunately, the underlying molecular mechanisms for its development and progression remain unclear. Studies have established that microRNAs (miRNAs) are dysregulated in PCa. The intron-derived microRNA-1207-3p (miR-1207-3p) is encoded at the non-protein coding gene locus PVT1 on the 8q24 human chromosomal region, an established PCa susceptibility locus. However, miR-1207-3p in PCa had not previously been investigated. Therefore, we explored if miR-1207-3p plays any regulatory role in PCa. We discovered that miR-1207-3p is significantly underexpressed in PCa cell lines in comparison to normal prostate epithelial cells, and …

A Machine Learning Classifier Trained On Cancer Transcriptomes Detects Nf1 Inactivation Signal In Glioblastoma, Gregory P. Way, Robert J. Allaway, Stephanie J. J. Bouley, Camilo E. Fadul, Yolanda Sanchez, Casey Greene

Dartmouth Scholarship

We have identified molecules that exhibit synthetic lethality in cells with loss of the neurofibromin 1 (NF1) tumor suppressor gene. However, recognizing tumors that have inactivation of the NF1 tumor suppressor function is challenging because the loss may occur via mechanisms that do not involve mutation of the genomic locus. Degradation of the NF1 protein, independent of NF1 mutation status, phenocopies inactivating mutations to drive tumors in human glioma cell lines. NF1 inactivation may alter the transcriptional landscape of a tumor and allow a machine learning classifier to detect which tumors will benefit from synthetic lethal molecules. We …

The Landscape Of Extreme Genomic Variation In The Highly Adaptable Atlantic Killifish, Noah M. Reid, Craig E. Jackson, Don Gilbert, Patrick Minx, Michael J. Montague, Thomas H. Hampton, Lily W. Helfrich, Benjamin L. King, Diane E. Nacci, Neel Aluru

Dartmouth Scholarship

Understanding and predicting the fate of populations in changing environments require knowledge about the mechanisms that support phenotypic plasticity and the adaptive value and evolutionary fate of genetic variation within populations. Atlantic killifish (Fundulus heteroclitus) exhibit extensive phenotypic plasticity that supports large population sizes in highly fluctuating estuarine environments. Populations have also evolved diverse local adaptations. To yield insights into the genomic variation that supports their adaptability, we sequenced a reference genome and 48 additional whole genomes from a wild population. Evolution of genes associated with cell cycle regulation and apoptosis is accelerated along the killifish lineage, which …

Rapid Bactericidal Activity Of An Amphiphilic Polyacrylate Terpolymer System Comprised Of Same-Centered Comonomers With 2-Carbon And 6- Carbon Spacer Arms And An Uncharged Repeat Unit, Kamia Punia, Ashish Punia, Kaushiki Chatterjee, Sumit Mukherjee, Jimmie E. Fata, Probal Banerjee, Krishnaswami Raja, Nan-Loh Yang

Publications and Research

The global health threat of antimicrobial resistance has created a pressing need to develop practical alternatives to conventional antibiotic agents. Peptide mimetic synthetic amphiphilic polymers are known to non-specifically disrupt the bacterial cell surface thus leading to highly hindered bacterial resistance development. We investigated the antibacterial activities of a terpolymer macromolecular architecture with a combination of 6- carbon and 2-carbon spacer arms (distance from polymer backbone to pendent cationic center) interspersed with counits with hydrophobic side groups. A random copolymer with a combination of 6-carbon spacer arm repeat units (60 mol%) and 2-carbon spacer arm (40 mol%) units is moderately …

Cancer patients often experience weight loss caused by protein calorie malnutrition (PCM) during the course of the disease or treatment. PCM is expressed as severe if the patient has two or more of the following characteristics: obvious significant muscle wasting, loss of subcutaneous fat; nutritional intake of <50% of recommended intake for 2 weeks or more; bedridden or otherwise significantly reduced functional capacity; weight loss of >2% in 1 week, 5% in 1 month, or 7.5% in 3 months. Cancer anorexiacachexia syndrome (CACS) is a multifactorial condition of advanced PCM associated with underlying illness (in this case cancer) and is characterized by loss of muscle with or without loss of fat mass. Cachexia is defined as weight loss of …
