Facial appearance depends on several oral and extraoral factors. The gingiva is an important intraoral tissue which when affected particularly by pigmentation is mainly responsible for the unpleasant appearance. Several causes of gingival pigmentation were previously mentioned in text together with the possible techniques of treatment. In this review, we will focus on this topic with a histological point of view.

Palatal Caliber Persistent Artery In A Diabetic Patient, Bacem A.E.O. Khalele

Future Dental Journal

Caliber persistent artery is a rarely reported lesion which prefers, given the underpinned literature, the labial arteries. This paper reports a very rare case of an isolated palatal ulcerative lesion in a non-insulin dependent diabetic patient. The patient refused to run any radiological tests, other than the periapical radiograph, but consented the incisional biopsy. Therefore, histochemical and immunohsitochemical stains were ushered to establish, non-invasively, a diagnosis. Accordingly, this paper explores the diagnostics and differential diagnosis of caliber persistent artery and reviews briefly the previously reported cases.

Gestation As Mothering, Timothy F. Murphy, Jennifer Parks

Philosophy: Faculty Publications and Other Works

Some commentators maintain that gestational surrogates are not ‘mothers’ in a way capable of grounding a claim to motherhood. These commentators find that the practices that constitute motherhood do not extend to gestational surrogates. We argue that gestational surrogates should be construed as mothers of the children they bear, even if they fully intend to surrender those children at birth to the care of others. These women stand in a certain relationship to the expected children: They live in changed moral circumstances by reason of their pregnancy, and they engage in the practices said to define motherhood in the post-birth …

Are We Prepared?: A Quantitative Study Of Elementary School Counselors' Knowledge, Skills, And Dispositions To Working With Lgbtq Youth, Kristina D. Weiss

Theses and Dissertations

It is estimated that there are over three million lesbian, gay, bisexual, transgender, and questioning (LGBTQ) youth in the United States. Based on their perceived or real sexual orientation and gender identity, these youth face multiple accounts of bias and discrimination in schools. As a source of solace, many LGBTQ students seek out adult supports in school, namely the school counselor. While extensive research exists about the interactions and capabilities of secondary school counselors to work with LGBTQ youth, there is a limited research surrounding elementary school counselor's competencies with this population. The purpose of this quantitative research was to …

Digenic Variants In The Fgf21 Signaling Pathway Associated With Severe Insulin Resistance And Pseudoacromegaly, Stephen I Stone, Daniel J Wegner, Jennifer A Wambach, F Sessions Cole, Fumihiko Urano, David M Ornitz

Open Access Publications

Insulin-mediated pseudoacromegaly (IMPA) is a rare disease of unknown etiology. Here we report a 12-year-old female with acanthosis nigricans, hirsutism, and acromegalic features characteristic of IMPA. The subject was noted to have normal growth hormone secretion, with extremely elevated insulin levels. Studies were undertaken to determine a potential genetic etiology for IMPA. The proband and her family members underwent whole exome sequencing. Functional studies were undertaken to validate the pathogenicity of candidate variant alleles. Whole exome sequencing identified monoallelic, predicted deleterious variants in genes that mediate fibroblast growth factor 21 (FGF21) signaling,

Investigation Of The Sequence-Structure-Activity Relationship In Ponericin L1 From Neoponera Goeldii & Synergistic Interactions Of Ionic Liquids And Antimicrobials To Improve Efficacy, Alexandria S. Senetra

Theses and Dissertations

Non-traditional antimicrobials have been an area of great interest due to the increasing prevalence of antimicrobial resistance (AMR) in bacteria. Antimicrobial peptides (AMPs) & ionic liquids (ILs) are two examples that have been investigated as a potential solution. Most AMPs are naturally derived & exhibit high selectivity against bacterial targets over host cells. The venom-derived peptide, ponericin L1 from Neoponera goeldii, was used to investigate the role of cationic residues & net charge on peptide activity. Using both in vitro & microbiological methods, L1 peptide & derivatives exhibited an alpha-helical conformation with enhanced binding to lipid vesicles containing anionic lipids …

Laws, Alberto Marcos Dolado, Ramón López-Higes, Belinda M. Brown, Fernando Maestú

Research outputs 2014 to 2021

BACKGROUND: Electrophysiological studies show that reductions in power within the alpha band are associated with the Alzheimer's disease (AD) continuum. Physical activity (PA) is a protective factor that has proved to reduce AD risk and pathological brain burden. Previous research has confirmed that exercise increases power in the alpha range. However, little is known regarding whether other non-modifiable risk factors for AD, such as increased age or APOE ε4 carriage, alter the association between PA and power in the alpha band. METHODS: The relationship between PA and alpha band power was examined in a sample of 113 healthy adults using …

Rhizobacterial Species Richness Improves Sorghum Growth And Soil Nutrient Synergism In A Nutrient-Poor Greenhouse Soil, Mohammad Radhi Sahib, Zahida H. Pervaiz, Mark A. Williams, Muhammad Saleem, Seth Debolt

Horticulture Faculty Publications

Although microbes influence plant growth, little is known about the impact of microbial diversity on plant fitness trade-offs, intraspecific-interactions, and soil nutrient dynamics in the context of biodiversity-ecosystem functioning (BEF) research. The BEF theory states that higher species richness can enhance ecosystem functioning. Thus, we hypothesize that rhizobacterial species richness will alter sorghum (Sorghum bicolor L.) growth, soil nutrient dynamics and interactions (antagonism or synergism) in a nutrient-poor greenhouse soil. Using six rhizobacterial species in a BEF experiment, we tested the impact of a species richness gradient (0, 1, 3, 5 or 6 species per community) on plant growth, …

Body Mass And Primary Molt Patterns Of Greater Sage-Grouse In Colorado, Clait E. Braun, Peter O. Dunn, Gregory T. Wann, Michael A. Schroeder, Jerry W. Hupp

Western North American Naturalist

Patterns in body mass and molt provide useful information about how birds interact with their environment and act as potential explanatory variables in behavioral and demographic differences among sex and age classes. We collected population data for Greater Sage-Grouse (Centrocercus urophasianus) in Jackson and Moffat counties, Colorado, from 1973 to 1993 prior to consideration of federal listing of the species under the Endangered Species Act. Using spotlights and long-handled nets, we located and captured Greater Sage-Grouse while they roosted (primarily at night). Each captured bird was banded and released near the site of capture. We recorded the molt …

Thionated Organic Compounds As Emerging Heavy-Atom-Free Photodynamic Therapy Agents, Luis A. Ortiz-Rodríguez, Carlos E. Crespo-Hernández

Faculty Scholarship

This minireview focuses on recent progress in developing heavy-atom-free photosensitizers based on the thionation of nucleic acid derivatives and other biocompatible organic compounds for prospective applications in photodynamic therapy. Particular attention is given to the use of thionated nucleobase derivatives as "one-two punch"photodynamic agents. These versatile photosensitizers can act as "Trojan horses"upon metabolization into DNA and exposure to activating light. Their incorporation into cellular DNA increases their selectivity and photodynamic efficacy against highly proliferating skin cancer tumor cells, while simultaneously enabling the use of low irradiation doses both in the presence and in the absence of molecular oxygen. Also reviewed …

Evaluating Red Wolf Scat To Deter Coyote Access To Urban Pastureland, Meghan M. Louis, Samuel M. Tucker, Michael K. Stoskopf, Suzanne Kennedy-Stoskopf

Human–Wildlife Interactions

Depredation of domestic livestock by wildlife is a leading source of human–wildlife conflict, often requiring intervention at the local level. Historically, these interventions have resulted in the use of lethal methods to remove the offending animal. In response to increased public opposition to lethal control methods, wildlife managers have sought to identify effective nonlethal biological options to mitigate wildlife depredations. In 2018, we tested the concept of a biological deterrent using red wolf (Canis rufus) scat that had historically been spread along fence lines to prevent depredation of lambs (Ovis aries) and kid goats (Capra …

Is The Banana Ripe? Andean Bear–Human Conflict In A Protected Area Of Colombia, Sergio Escobar-Lasso, Juan C. Cepeda-Duque, Margarita Gil-Fernández, José F. González-Maya

Human–Wildlife Interactions

The Andean bear (Tremarctos ornatus; bear) is endemic to the tropical Andes Mountains of South America. Previous assessments predict that bear populations will decline by >30% in the next 30 years. The species may face the greatest threats within its historical distribution in Colombia where rapid agricultural expansion into natural habitats is increasing human–bear conflicts. Between April 2017 and March 2018, we studied bear feeding behavior on plantain (Musa sapientum) and banana (M. paradisiaca) crops within the Barbas-Bremen protected area in the central mountain range of Colombia to describe the magnitude of crop …

Ecological Factors Influencing Wild Pig Damage To Planted Pine And Hardwood Seedlings, Micah P. Fern, James B. Armstrong, Rebecca J. Barlow, John S. Kush

Human–Wildlife Interactions

Expanding wild pig (Sus scrofa) populations across the southern United States has the potential to impact longleaf pine (Pinus palustris) restoration efforts. The depredation of planted pine seedlings is the most widespread and economically costly damage caused by wild pigs in forest plantations. A better understanding of the ecological factors affecting depredation rates will allow managers to implement best management practices to reduce seedling mortality from wild pigs at their most vulnerable stage of growth. From March 2016 to March 2017, we evaluated wild pig preferences for planted pine and hardwood species at a 34.4-ha cutover …

Stoichiometrically Coupled Carbon And Nitrogen Cycling In The Microbial-Mineral Carbon Stabilization Model Version 1.0 (Mimics-Cn V1.0), Emily Kyker-Snowman, William R. Wieder, Serita D. Frey, A. Stuart Grandy

Faculty Publications

Explicit consideration of microbial physiology in soil biogeochemical models that represent coupled carbon–nitrogen dynamics presents opportunities to deepen understanding of ecosystem responses to environmental change. The MIcrobial-MIneral Carbon Stabilization (MIMICS) model explicitly represents microbial physiology and physicochemical stabilization of soil carbon (C) on regional and global scales. Here we present a new version of MIMICS with coupled C and nitrogen (N) cycling through litter, microbial, and soil organic matter (SOM) pools. The model was parameterized and validated against C and N data from the Long-Term Inter-site Decomposition Experiment Team (LIDET; six litter types, 10 years of observations, and 13 sites …
