Visualization Of Brown Fat Using X-Ray Dark Field Imaging, Troy D. Jacobs 2020 Louisiana State University and Agricultural and Mechanical College

Visualization Of Brown Fat Using X-Ray Dark Field Imaging, Troy D. Jacobs

LSU Master's Theses

Introduction: Obesity has become a major societal issue. Many researchers are looking for ways to combat this growing epidemic. Brown adipose tissue (BAT) might be a way to help individuals overcome the challenges associated with weight loss and maintenance of weight loss, but a better understanding of BAT and how to control and utilize it is needed. BAT differs from white adipose tissue (WAT) in that BAT is rich with mitochondria and therefore is metabolically active. BAT is a source of non-shivering thermogenesis and can be activated both by cold exposure and pharmacologically. Current methods of assessing BAT activity are ...

Utilizing Best Practices Of 3d-Modeling And Printing In Veterinary Medicine To Analyze Elbow Incongruity Of A Maltese Canine, Johnny Altwal 2020 Chapman University

Utilizing Best Practices Of 3d-Modeling And Printing In Veterinary Medicine To Analyze Elbow Incongruity Of A Maltese Canine, Johnny Altwal

Student Scholar Symposium Abstracts and Posters

Research on the application of 3D-printed models in human medicine is extensive, but it is relatively new for veterinary medicine. With the increased numbers of certified veterinary radiologists and animal imaging facilities, best practices in 3D model design and printing can be explored. This project was two-fold. First, an encompassing literature review was generated, outlining the development and uses of computer-generated 3D models in connection to their applications in veterinary medicine. Accurate renderings of an animal’s anatomy can be used to train new students, educate clients on their pets’ needs, and guide veterinarian surgical approaches. Several different cases were ...


The Effect Of Hypoxia On Brain Cell Proliferation In Weakly Electric Fish, Petrocephalus Degeni, Kaitlin Klovdahl 2020 Trinity College

The Effect Of Hypoxia On Brain Cell Proliferation In Weakly Electric Fish, Petrocephalus Degeni, Kaitlin Klovdahl

Senior Theses and Projects

Oxygen levels tend to remain at a steady state concentration in the Earth’s atmosphere, yet in some bodies of water, they can fluctuate and decrease drastically. Many organisms that inhabit the swamps, lakes, streams, and parts of the ocean where this occurs have evolved adaptations to manage this environmental uncertainty and continue normal oxygen consumption. The Lwamunda swamp in Uganda is chronically hypoxic, yet it is home to many species, including the electric fish Petrocephalus degeni. P. degeni are unusual by nature of their immense brain, and the Lwamunda swamp appears ill-suited for maintaining this large, metabolically active organ ...


Distal Urogenital Anatomy Of Male Prairie Racerunners, Aspidoscelis Sexlineatus Viridis (Reptilia: Sauria: Teiidae), Stanley E. Trauth 2020 Arkansas State University

Distal Urogenital Anatomy Of Male Prairie Racerunners, Aspidoscelis Sexlineatus Viridis (Reptilia: Sauria: Teiidae), Stanley E. Trauth

Journal of the Arkansas Academy of Science

I examined histologically the distal urogenital anatomy in male Prairie Racerunners (Aspidoscelis sexlineatus viridis) from a small seasonal sample of individuals collected in Arkansas in order to provide additional information regarding squamate urogenital anatomy. Specifically, I focused on the basic anatomy and positioning of posterior ducts and associated structures in this teiid lizard. The anatomical structures included the ductus deferens, ampulla ductus deferens, ampulla urogenital papilla (Aup), ureter, inner core tissue mass, urodaeum, and the urogenital papilla. The two Aup, which are small complimentary blind pouches representing the terminal repositories for products released by urogenital ducts, are striking anatomical features ...


Bioenergetic Functions In Subpopulations Of Heart Mitochondria Are Preserved In A Non-Obese Type 2 Diabetes Rat Model (Goto-Kakizaki), Nicola Lai, C. M. Kummitha, F. Loy, R. Isola, C. L. Hoppel 2020 Old Dominion University

Bioenergetic Functions In Subpopulations Of Heart Mitochondria Are Preserved In A Non-Obese Type 2 Diabetes Rat Model (Goto-Kakizaki), Nicola Lai, C. M. Kummitha, F. Loy, R. Isola, C. L. Hoppel

Electrical & Computer Engineering Faculty Publications

A distinct bioenergetic impairment of heart mitochondrial subpopulations in diabetic cardiomyopathy is associated with obesity; however, many type 2 diabetic (T2DM) patients with high-risk for cardiovascular disease are not obese. In the absence of obesity, it is unclear whether bioenergetic function in the subpopulations of mitochondria is affected in heart with T2DM. To address this issue, a rat model of non-obese T2DM was used to study heart mitochondrial energy metabolism, measuring bioenergetics and enzyme activities of the electron transport chain (ETC). Oxidative phosphorylation in the presence of substrates for ETC and ETC activities in both populations of heart mitochondria in ...


Comparative Anatomy Case Study: Differences In Extrinsic Eye Muscles And Dissection Protocols, Erin Ruden 2020 Iowa State University

Comparative Anatomy Case Study: Differences In Extrinsic Eye Muscles And Dissection Protocols, Erin Ruden

Creative Components

There have been notable studies comparing the eye placement between predators and prey, which can be further categorized as omnivore, carnivore, and herbivore. The purpose of this study was to determine if eye placement correlated with extrinsic eye muscle differences among the classification of animals (predator vs. prey and omnivore vs. carnivore vs. herbivore). For an omnivore, a human orbit was dissected. A cat was dissected to represent a carnivore and a goat was dissected to represent an herbivore. Dissection protocol for the cat and goat were created due to the lack of dissections of these muscles. Unfortunately, data collection ...


Neuroanatomy Of The Blackspotted Rockskipper, Entomacrodus Striatus, Pooja Dayal 2020 The University of Akron

Neuroanatomy Of The Blackspotted Rockskipper, Entomacrodus Striatus, Pooja Dayal

Williams Honors College, Honors Research Projects

Here I characterized the central neuroanatomy of the Blackspotted Rockskipper, Entomacrodus striatus, native to French Polynesia. The neuroanatomy of E. striatus has not been studied prior to this paper. I used several histology and antibody staining techniques to accomplish this, including Crystal Violet, immunohistochemistry, immunofluorescence, and Bielschowsky’s Silver Nitrate staining. This paper describes the most successful techniques used, identifies major structures in the species’ neuroanatomy, and also explains why studying E. striatus is important in the future of vertebrate research.


Oral Contraceptives As Possible Acl Injury Prevention Method, Haley Schweizer 2020 Arcadia University

Oral Contraceptives As Possible Acl Injury Prevention Method, Haley Schweizer

Capstone Showcase

ABSTRACT

Introduction: Anterior Cruciate Ligament (ACL) injuries are an upsetting setback for many athletes that require a long and costly recovery process. The injury rates are four times greater in women than men. Preventative measures that help to prevent ACL injuries are limited to stretching and strengthening. Therefore, this review aims to investigate if oral contraceptive [I] usage provides a possible new avenue for prevention of ACL injury [O] in young female athletes (ages 18-30) [P] compared to those that do not take oral contraceptives [C].

Methods: A literature review was performed though PubMed, Google Scholar, SCOPUS Database, and ClinicalKey ...


Bone Mineral Density Of The Common Bottlenose Dolphin, Tursiops Truncatus: A Proposed Model For Monitoring Osteological And Ecosystem Health, James Wright Burrus Powell 2019 Portland State University

Bone Mineral Density Of The Common Bottlenose Dolphin, Tursiops Truncatus: A Proposed Model For Monitoring Osteological And Ecosystem Health, James Wright Burrus Powell

Dissertations and Theses

Bone mineral density (BMD) in the pectoral flipper of the common bottlenose dolphin, Tursiops truncatus, was examined to address the need to define a comprehensive target site for clinical osteodensitometric assessment and to establish ranges of observed bone density values for this species. Radii were analyzed using dual energy X-ray absorptiometry (DXA), the accepted standard in human medical studies. Multiple loci within the radius were identified and assessed for their correlation to BMD of the entire bone. Radii BMD were also examined for differences based on sex, age, total body length, handedness, geographical affinity, and nutritional status at time of ...


Gingival Taste Bud Papillae Associated With Retromolar Salivary Gland, Quan Nguyen, Marco Tizzano, Bekir Karabucak, Grace Beck Coburn 2019 Monell Chemical Senses Center

Gingival Taste Bud Papillae Associated With Retromolar Salivary Gland, Quan Nguyen, Marco Tizzano, Bekir Karabucak, Grace Beck Coburn

Dental Theses

Taste in the gustatory system allows to distinguish between safe and harmful food, and to gauge its nutritional value. Digestive enzymes in saliva begin to dissolve food into base chemicals that are detected by taste buds containing three different cell types involved in the perception of the five basic tastes. Von Ebner's glands, found adjacent to the moats surrounding the circumvallate (CV) and foliate papillae, are exocrine salivary glands that secrete digestive enzymes and presumably flush material out of the papillae. Recently, we rediscovered and characterized anatomically and molecularly a chemosensory structure in the mouse oral cavity consisting of ...


Goats Distinguish Between Positive And Negative Emotion-Linked Vocalisations, Luigi Baciadonna, Elodie Briefer, Livio Favaro, A. G. McElligott 2019 Queen Mary University of London

Goats Distinguish Between Positive And Negative Emotion-Linked Vocalisations, Luigi Baciadonna, Elodie Briefer, Livio Favaro, A. G. Mcelligott

Bioacoustics Collection

Background: Evidence from humans suggests that the expression of emotions can regulate social interactions and promote coordination within a group. Despite its evolutionary importance, social communication of emotions in non-human animals is still not well understood. Here, we combine behavioural and physiological measures, to determine if animals can distinguish between vocalisations linked to different emotional valences (positive and negative). Using a playback paradigm, goats were habituated to listen to a conspecific call associated with positive or negative valence (habituation phase) and were subsequently exposed to a variant of the same call type (contact call) associated with the opposite valence (dishabituation ...


Perception Of Emotional Valence In Horse Whinnies, Elodie Briefer, Roi Mandel, Anne-Laure Maigrot, Sabrina Briefer Freymond, Iris Bachmann, Edna Hillmann 2019 ETH Zürich

Perception Of Emotional Valence In Horse Whinnies, Elodie Briefer, Roi Mandel, Anne-Laure Maigrot, Sabrina Briefer Freymond, Iris Bachmann, Edna Hillmann

Elodie Briefer, PhD

Background: Non-human animals often produce different types of vocalisations in negative and positive contexts (i.e. different valence), similar to humans, in which crying is associated with negative emotions and laughter is associated with positive ones. However, some types of vocalisations (e.g. contact calls, human speech) can be produced in both negative and positive contexts, and changes in valence are only accompanied by slight structural differences. Although such acoustically graded signals associated with opposite valence have been highlighted in some species, it is not known if conspecifics discriminate them, and if contagion of emotional valence occurs as a result ...

Encoding Of Emotional Valence In Wild Boar (Sus Scrofa) Calls, Anne-Laure Maigrot, Edna Hillmann, Elodie Briefer

Elodie Briefer, PhD

Measuring emotions in nonhuman mammals is challenging. As animals are not able to verbally report how they feel, we need to find reliable indicators to assess their emotional state. Emotions can be described using two key dimensions: valence (negative or positive) and arousal (bodily activation or excitation). In this study, we investigated vocal expression of emotional valence in wild boars (Sus scrofa). The animals were observed in three naturally occurring situations: anticipation of a food reward (positive), affiliative interactions (positive), and agonistic interactions (negative). Body movement was used as an indicator of emotional arousal to control for the effect of ...


Decomposition Of Pig Carcasses At Varying Room Temperature, Jacqueline Abad Santos 2019 San Jose State University

Decomposition Of Pig Carcasses At Varying Room Temperature, Jacqueline Abad Santos

Themis: Research Journal of Justice Studies and Forensic Science

The goal of this study is to assess the qualitative scoring of decomposition scales with statistical analysis while also determining which indoor environment will decompose the fastest. When comparing the three indoor environments, water decomposition appears to be the fastest, but the method of analysis for this study determines that using decomposition scales to analyze such environments may produce statistically insignificant results. For this study, piglets were put in a dry steel tub, a water filled steel tub, and a suitcase. These were recorded using photographs for 25 days and then scored using decomposition scales. The total score was divided ...


Defects In Fetal Mouth Movement And Pharyngeal Patterning Underlie Cleft Palate Caused By Retinoid Deficiency., Regina Friedl 2019 University of Louisville

Defects In Fetal Mouth Movement And Pharyngeal Patterning Underlie Cleft Palate Caused By Retinoid Deficiency., Regina Friedl

Electronic Theses and Dissertations

Cleft palate is a common birth defect. Etiologic mechanisms of palate cleft include defects in palate morphogenesis, mandibular growth, or spontaneous fetal mouth movement. Cleft palate linked to deficient fetal mouth movement has been demonstrated directly only in a single experimental model of loss of neurotransmission. Here, using retinoid deficient mouse embryos, we demonstrate directly for the first time that deficient fetal mouth movement and cleft palate occurs as a result of mis-patterned development of pharyngeal peripheral nerves and cartilages. Retinoid deficient embryos were generated by inactivation of retinol dehydrogenase 10 (Rdh10), which is critical for production of Retinoic Acid ...


Mobilization Of Calcium Across Mineralized Tissues In Yellow Perch, Perca Flavescens, Taylor Bopp 2019 University of Lynchburg

Mobilization Of Calcium Across Mineralized Tissues In Yellow Perch, Perca Flavescens, Taylor Bopp

Student Scholar Showcase

Bones in many higher teleost fish, such as percids and centrarchids, lack osteocytes that function as both chemo- and mechano-sensors, and thus, are not actively involved in homeostasis of blood calcium level. Nonetheless, the vertebrae of yellow perch, Perca flavescens (P. flavescens), living in darker and low calcium (Ca) water, have demonstrated adaptive modeling and remodeling of vertebrae to be more mineralized and thus enhance transmission of the axial muscle torque into the thrust force for the C-start predator escape behavior. The prey-predator interaction is expected to occur at closer range between prey fish and predator fish in darker water ...


Using Ct Scans To Describe An Allosaurus Skull (Dinosauria: Theropoda), Jordan C. Oldham 2019 Cedarville University

Using Ct Scans To Describe An Allosaurus Skull (Dinosauria: Theropoda), Jordan C. Oldham

The Research and Scholarship Symposium (2013-2019)

In 2001, an Allosaurus skull (CMP 279) was discovered in the Skull Creek Basin in Moffat County, Colorado. The skull is one of the most complete for the species and even contains the hyoid bones, which are usually not present. The skull is now permanently mounted, for display purposes, thus making the study of the individual bones difficult for producing a paleo-anatomical description. Computed Tomography (CT) scans of CMP 279 were created in 2017 and then made available for this study in 2019. CT scans are being used to investigate internal anatomy of skulls such as the endocranial cavity, sinuses ...


Arterial Distribution Of The Human Aorta: An Examination Of The Evolutionary, Developmental, And Physiological Bases Of Asymmetry., Brandon Oddo, Cooker Storm 2019 Pepperdine University

Arterial Distribution Of The Human Aorta: An Examination Of The Evolutionary, Developmental, And Physiological Bases Of Asymmetry., Brandon Oddo, Cooker Storm

Seaver College Research And Scholarly Achievement Symposium

The study of anatomy contends that “form follows function”; a disciplinary theme purporting that anatomical structures (i.e., cells, tissues, and organs) have a shape that serves its proper function. With this in mind, it is unclear why human arterial distribution off the aortic arch is asymmetrical, while the corresponding venous anatomy is symmetrical. We investigated the evolutionary, developmental, and physiological bases for the asymmetry of aortic arch branches in humans. First, we investigated the cardiovascular anatomy of ancestral species to determine if, and at what level, anatomical divergence (from aortic symmetry to asymmetry) occurs. Second, we examined the formation ...
