Bulletin of Chinese Academy of Sciences (Chinese Version)

The degradation problems of soil erosion, soil acidification, soil fertility attenuation, soil heavy metal pollution, and seasonal drought in the red soil hilly region of Southeast China have resulted in the degradation of the red soil ecosystem and the decline of the land productivity, which restricts the sustainable development of regional agriculture. Since the establishment of Yingtan Red Soil Ecological Experiment Station in 1985, the long-term observation and ecological basic research of red soil ecosystems have been carried out, the application research and demonstration have been implemented on soil degradation and restoration, soil quality evolution and improvement, nutrient cycling and …

Beta1pix Exchange Factor Stabilizes The Ubiquitin Ligase Nedd4-2 And Plays A Critical Role In Enac Regulation By Ampk In Kidney Epithelial Cells, Pei-Yin Ho, Hui Li, Tengis S. Pavlov, Roland D. Tuerk, Diego Tabares, René Brunisholz, Dietbert Neumann, Alexander Staruschenko, Kenneth R. Hallows

Hypertension and Vascular Research Articles

Our previous work has established that the metabolic sensor AMP-activated protein kinase (AMPK) inhibits the epithelial Na+ channel (ENaC) by promoting its binding to neural precursor cell-expressed, developmentally down-regulated 4-2, E3 ubiquitin protein ligase (Nedd4-2). Here, using MS analysis and in vitro phosphorylation, we show that AMPK phosphorylates Nedd4-2 at the Ser-444 (Xenopus Nedd4-2) site critical for Nedd4-2 stability. We further demonstrate that the Pak-interacting exchange factor β1Pix is required for AMPK-mediated inhibition of ENaC-dependent currents in both CHO and murine kidney cortical collecting duct (CCD) cells. Short hairpin RNA-mediated knockdown of β1Pix expression in CCD cells attenuated the …

Re-Conceptualizing Foreignness : The English Translation Of Chinese Calligraphic Culture, Ge Song

Lingnan Theses (MPhil & PhD)

Foreignness is one primary concern of Translation Studies. Chinese calligraphy, with its unique aesthetic pursuits and cultural underpinnings, presents an unusual case of foreign otherness in relation to the English language. Thus, theories derived from the translation of Chinese calligraphic culture into English can contribute to our existing knowledge of the nature of translation. Despite sporadic endeavors, translation issues related to Chinese calligraphy remain largely under-researched. This thesis constructs a theoretical framework that offers new perspectives on translating foreignness by exploring how the culture of Chinese calligraphy, concretized in the discourses of classical treatises, has been translated into English since …

A Foucaultian Discourse Analysis Of Person-Centered Practice Using A Genealogical Framework Of Intellectual Disability, Nick Winges-Yanez

Dissertations and Theses

A genealogical framework highlights the important role sexuality has played in constructing the current label of intellectual disability (ID). The genealogical framework is meant to replace the social, medical, and/or rights-based model(s) that have dominated social work and social services working in the disability field. With this framework, or perspective, I use a Foucaultian discourse analysis to read through seminal texts regarding person-centered practice.

Person-centered practice is the foremost intervention used in social work, and other disciplines, to work with people labeled with intellectual disability. My research questions focus on what is revealed about ID in PCP through a genealogical …

Iceland: The Heat Of Change Empirical Study On Icelanders Perceptions And Observations Of Global Warming, Katalina Montalvo

Student Works

Iceland as a northern country glazed with snow and ice, beholding a diverse ecosystem. Temperature has a large impact and climate change has made its presence immediately felt. The increase in water temperature has brought new species to the land and seas of Iceland causing others to reduce in populations or having to move away to find more food or both. The research project reviews the effects of climate in Iceland, the damage the increase in temperature is causing to its fragile ecosystem, and Icelanders account of this change. Data was collected through interviews of native Icelanders, field observations, and …

Vocabulary! Supporting Diverse Students’ Mastery Of The Vocabulary, Lissa Power-Defur

Summer Literacy Institute

Mastering vocabulary is challenging for second language learners, students with disabilities, and students who are at risk. Given the vast number of words students must master prior to graduation (over 100,000), it is impossible for teachers and specialists to teach students all the words they need to know. Hart and Risley’s landmark study of the language of children from diverse families informs us that all school personnel need to focus on vocabulary. The Virginia Department of Education’s analysis of students performance on the Standards of Learning indicates that weaknesses in vocabulary knowledge adversely effect student’s performance in the general curriculum …

Goats Prefer Positive Human Emotional Facial Expressions, Christian Nawroth, Natalia Albuquerque, Carine Savalli, Marie-Sophie Single, Alan G. Mcelligott

Social Cognition Collection

Domestication has shaped the physiology and the behaviour of animals to better adapt to human environments. Therefore, human facial expressions may be highly informative for animals domesticated for working closely with people, such as dogs and horses. However, it is not known whether other animals, and particularly those domesticated primarily for production, such as goats, are capable of perceiving human emotional cues. In this study, we investigated whether goats can distinguish human facial expressions when simultaneously shown two images of an unfamiliar human with different emotional valences (positive/ happy or negative/angry). Both images were vertically attached to a wall on …

Conley, Darren L. Johnson, Emily K. Reinke, Laura J. Huston, Janet L. Huebner, Ching-Heng Chou, Virginia B. Kraus, Kurt P. Spindler, Cale A. Jacobs

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background. The majority of patients develop posttraumatic osteoarthritis within 15 years of anterior cruciate ligament (ACL) injury. Inflammatory and chondrodegenerative biomarkers have been associated with both pain and the progression of osteoarthritis; however, it remains unclear if preoperative biomarkers differ for patients with inferior postoperative outcomes. Hypothesis/Purpose. The purpose of this pilot study was to compare biomarkers collected on the day of ACL reconstruction between patients with "good" or "poor" 2-year postoperative outcomes. We hypothesized that inflammatory cytokines and chondrodegenerative biomarker concentrations would be significantly greater in patients with poorer outcomes. Study Design. Prospective cohort design. Methods. 22 …

Genomic Analysis Of 48 Paenibacillus Larvae Bacteriophages, Casey Stamereilers, Christopher P. Fajardo, Jamison K. Walker, Katterinne N. Mendez, Eduardo Castro-Nallar, Julianne H. Grose, Sandra Hope, Philippos K. Tsourkas

Life Sciences Faculty Research

The antibiotic-resistant bacterium Paenibacillus larvae is the causative agent of American foulbrood (AFB), currently the most destructive bacterial disease in honeybees. Phages that infect P. larvae were isolated as early as the 1950s, but it is only in recent years that P. larvae phage genomes have been sequenced and annotated. In this study we analyze the genomes of all 48 currently sequenced P. larvae phage genomes and classify them into four clusters and a singleton. The majority of P. larvaephage genomes are in the 38–45 kbp range and use the cohesive ends (cos) DNA-packaging strategy, while a minority have genomes …

L-Citrulline Supplementation: Impact On Cardiometabolic Health, Timothy D. Allerton, David N. Proctor, Jacqueline M. Stephens, Tammy R. Dugas, Guillaume Spielmann, Brian A. Irving

Faculty Publications

© 2018 by the authors. Licensee MDPI, Basel, Switzerland. Diminished bioavailability of nitric oxide (NO), the gaseous signaling molecule involved in the regulation of numerous vital biological functions, contributes to the development and progression of multiple age-and lifestyle-related diseases. While L-arginine is the precursor for the synthesis of NO by endothelial-nitric oxide synthase (eNOS), oral L-arginine supplementation is largely ineffective at increasing NO synthesis and/or bioavailability for a variety of reasons. L-citrulline, found in high concentrations in watermelon, is a neutral alpha-amino acid formed by enzymes in the mitochondria that also serves as a substrate for recycling L-arginine. Unlike L-arginine, …

Removal Of Invasive Plants From Pando Exclosure 2018, Marc Coles-Ritchie

Aspen Bibliography

On July 10-11, 2018 volunteers and staff from Great Old Broads for Wilderness and Grand Canyon Trust removed invasive plants from the Pando exclosure, a fenced portion of the Pando Clone aspen forest adjacent to Fish Lake, in Central Utah. This area has been fenced to restore a portion of the Pando Clone that has been lacking recruitment for decades, by protecting young aspen from browsing by deer and cattle. We have been removing invasive species for five years from this exclosure.

The 2018 trip included 10 women and one staffer of Great Old Broads for Wilderness, from the states …

Roost Characteristics And Clustering Behavior Of Western Red Bats (Lasiurus Blossevillii) In Southwestern New Mexico, Brett R. Andersen, Keith Geluso

Western North American Naturalist

The western red bat (Lasiurus blossevillii) is a foliage-roosting species of riparian habitats in arid regions of the southwestern United States. Only limited published anecdotal observations exist for roost sites used by this species. Western red bats were split taxonomically from the eastern red bat (Lasiurus borealis) in 1988, but summaries of roosting behaviors for western red bats still appear to stem from former associations with the commonly studied eastern red bat. Our study represents the first comprehensive research on the roosting ecology of western red bats. We radio-tracked 14 adult bats to 19 different day …

Bat Hibernacula In Caves Of Southern Idaho: Implications For Monitoring And Management, Jericho C. Whiting, Bill Doering, Gary Wright, Devin K. Englestead, Justin A. Frye, Todd Stefanic

Western North American Naturalist

Bat populations are being impacted by many threats, including white-nose syndrome, wind energy development, and hibernaculum disturbance and modification. Understanding the use of caves as hibernacula by bats in the western United States is necessary for the conservation and management of these mammals and their habitat, as well as for monitoring the arrival of white-nose syndrome. We identified biologically important hibernacula from 304 winter surveys (1 November–31 March) in 64 caves from 1984 to 2016 in southern Idaho, USA. During surveys researchers counted 37,693 bats representing 6 species. Townsend’s big-eared bats (Corynorhinus townsendii townsendii) comprised 96.1% (36,237 individuals …

Genomic Inference Of The Metabolism And Evolution Of The Archaeal Phylum Aigarchaeota, Zheng-Shuang Hua, Yan-Ni Qu, Qiyun Zhu, En-Min Zhou, Yan-Ling Qi, Yi-Rui Yin, Yang-Zhi Rao, Ye Tian, Yu-Xian Li, Lan Liu, Cindy J. Castelle, Brian P. Hedlund, Wen-Sheng Shu, Rob Knight, Wen-Jun Li

Life Sciences Faculty Research

Microbes of the phylum Aigarchaeota are widely distributed in geothermal environments, but their physiological and ecological roles are poorly understood. Here we analyze six Aigarchaeota metagenomic bins from two circumneutral hot springs in Tengchong, China, to reveal that they are either strict or facultative anaerobes, and most are chemolithotrophs that can perform sulfide oxidation. Applying comparative genomics to the Thaumarchaeota and Aigarchaeota, we find that they both originated from thermal habitats, sharing 1154 genes with their common ancestor. Horizontal gene transfer played a crucial role in shaping genetic diversity of Aigarchaeota and led to functional partitioning and ecological divergence among …

Cross-Life Stage Effects Of Aquatic Larval Density And Terrestrial Moisture On Growth And Corticosterone In The Spotted Salamander, Julie F. Charbonnier, Jacquelyn Pearlmutter, James R. Vonesh, Caitlin R. Gabor, Zachery R. Forsburg, Kristine L. Grayson

Biology Faculty Publications

For organisms with complex life cycles, conditions experienced during early life stages may constrain later growth and survival. Conversely, compensatory mechanisms may attenuate negative effects from early life stages. We used the spotted salamander, Ambystoma maculatum, to test how aquatic larval density and terrestrial moisture influence juvenile growth, food intake, evaporative water loss and water reuptake rates, and corticosterone levels. We conducted an outdoor mesocosm experiment to manipulate larval density and transferred metamorphosed salamanders into low and high terrestrial moisture treatments in laboratory terrariums. After the larval stage, high-density salamanders were significantly smaller and had higher corticosterone release rates …

Drosophila Species Learn Dialects Through Communal Living, Balint Z. Kacsoh, Julianna Bozler, Giovanni Bosco

Dartmouth Scholarship

Many species are able to share information about their environment by communicating through auditory, visual, and olfactory cues. In Drosophila melanogaster, exposure to para- sitoid wasps leads to a decline in egg laying, and exposed females communicate this threat to naïve flies, which also depress egg laying. We find that species across the genus Drosophila respond to wasps by egg laying reduction, activate cleaved caspase in oocytes, and communicate the presence of wasps to naïve individuals. Communication within a species and between closely related species is efficient, while more distantly related species exhibit partial communication. Remarkably, partial communication between …

Whole Cell Cross-Linking To Discover Host-Microbe Protein Cognate Receptor/Ligand Pairs, Bart C. Weimer, Poyin Chen, Prerak T. Desai, Dong Chen, Jigna Shah

Biological Engineering Faculty Publications

Bacterial surface ligands mediate interactions with the host cell during association that determines the specific outcome for the host–microbe association. The association begins with receptors on the host cell binding ligands on the microbial cell to form a partnership that initiates responses in both cells. Methods to determine the specific cognate partnerships are lacking. Determining these molecular interactions between the host and microbial surfaces are difficult, yet crucial in defining biologically important events that are triggered during association of the microbiome, and critical in defining the initiating signal from the host membrane that results in pathology or commensal association. In …

Different Behavioral Experiences Produce Distinctive Parallel Changes In, And Correlate With, Frontal Cortex And Hippocampal Global Post-Translational Histone Levels., Marissa Sobolewski, Garima Singh, Jay S. Schneider, Deborah A. Cory-Slechta

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

While it is clear that behavioral experience modulates epigenetic profiles, it is less evident how the nature of that experience influences outcomes and whether epigenetic/genetic "biomarkers" could be extracted to classify different types of behavioral experience. To begin to address this question, male and female mice were subjected to either a Fixed Interval (FI) schedule of food reward, or a single episode of forced swim followed by restraint stress, or no explicit behavioral experience after which global expression levels of two activating (H3K9ac and H3K4me3) and two repressive (H3K9me2 and H3k27me3) post-translational histone modifications (PTHMs), were measured in hippocampus (HIPP) …

New State Record And Potential Distribution Of The Snake Sibon Nebulatus From Mexico, Luis Badillo-Saldaña, Jose Daniel Lara-Tufiño, Aurelio Ramírez-Bautista, Jonathan A. Campbell

Western North American Naturalist

We report the northernmost Atlantic Coast record of the Cloudy Snail Sucker (Sibon nebulatus) from the state of Hidalgo, at a straight-line distance of about 185-km from the nearest historical locality in Sierra Norte de Puebla, Mexico. We assess the potential distribution of this species and compare morphological characteristics of specimens from Mexico and Central America. No significant morphometric or meristic differences were found. A species distribution model suggests that S. nebulatus is widely distributed on both coasts of Mexico, with a high probability of occurrence at a wider range of latitudes than current records indicate.

Oligodendrocytes (OLs) are the myelin-forming cells of the central nervous system. They are derived from differentiation of oligodendrocyte progenitors through a process requiring cell cycle exit and histone modifications. Here we identify the histone arginine methyl-transferase PRMT5, a molecule catalyzing symmetric methylation of histone H4R3, as critical for developmental myelination. PRMT5 pharmacological inhibition, CRISPR/cas9 targeting, or genetic ablation decrease p53-dependent survival and impair differentiation without affecting proliferation. Conditional ablation of Prmt5 in progenitors results in hypomyelination, reduced survival and differentiation. Decreased histone H4R3 symmetric methylation is followed by increased nuclear acetylation of H4K5, and is rescued by pharmacological inhibition of …

The Underdog Narrative In Movies: When Our Memories Fail Us, Nadav Goldschmied, Jessica Ruiz, Sydney Olagaray

Heroism Science

Heroes who win are adulated. Underdogs are a special class of heroes who are facing especially daunting odds. Why do people extend support to underdog entities in light of their bleak odds for triumph? The current study explored the idea that the underdog narrative is one of ultimate success and that this schema is strong enough to elicit false memories. We surveyed participants’ recollections of two boxing movies. As predicted, participants accurately remembered James Braddock beating the world champion in the end of Cinderella Man (underdog consistent plot) but failed to recall Apollo Creed beating Rocky Balboa in Rocky I …
