Design, Fabrication, And Evaluation Of 3-D-Printed Cystotomy Spoons As A Retrieval Method In Dogs, Davina C. D'Angelo, Sam E. Stephens, Morten O. Jensen, Lauren R. Thomas

Animal Science Faculty Publications and Presentations

OBJECTIVE

Current cystotomy methods often implement the use of off-label devices, resulting in urocystolith extraction difficulty and potentially leading to postoperative complications and discomfort for the patient. The objective of this study was to create 3 novel 3-D printed cystotomy spoons that offer a dedicated solution for removing urocystoliths from a patient's urinary bladder.

ANIMALS

Clinical use of the 3 novel 3-D printed cystotomy spoons were ultimately evaluated in 4 dogs and 1 cat that presented for urocystotlith removal at 3 different veterinary hospitals in northwest Arkansas.

METHODS

The novel cystotomy spoons were designed using SolidWorks, 3-D printed with a …

The Morphology And Evolution Of The Primate Brachial Plexus, Brian M. Shearer

Dissertations, Theses, and Capstone Projects

Primate evolutionary history is inexorably linked to the evolution of a broad array of locomotor adaptations that have facilitated the clade’s invasion of new niches. Researchers studying the evolution of primates and of their individual locomotor adaptations have traditionally relied on bony morphology – a practical choice given the virtual non-existence of any other type of tissue in the fossil record. However, this focus downplays the potential importance of the many other structures involved in locomotion, such as muscle, cartilage, and neural tissue, which may each be influenced by separate selective forces because of their different roles in facilitating movement. …

Rehabilitation Of An Injured Golden Eagle (Aquila Chrysaetos): A Case Study, Fida Muhammad Khan, Fakhar-I- Abbas, Abu Ul Hassan Faiz

Journal of Bioresource Management

Habitat destruction and anthropogenic activities cause wild birds to migrate towards urban areas in search of food and sometimes nesting in high-roof buildings, where they are caught by local people using different techniques and are further used for hunting or recreational purposes. An injured Golden Eagle (Aquila chrysaetos) was found entangled in bushes near the vicinity of Balkasar Research Complex, Chakwal, Pakistan. After complete physical examination, a wound on the right wing and closed leg fracture was diagnosed. The successful treatment was done by anti-parasitic and anti-bacterial drugs with careful monitoring. Splint was adjusted after aligning the fractured …

Effects Of 17Β Estradiol In The Metabolism And Morphology Of Bluegill Sunfish (Lepomis Macrochirus), Neeta Parajulee Karki

Masters Theses

Fish natural habitats are increasingly contaminated with various estrogenic compounds, including 17β estradiol (E2). This compound causes adverse effects on the reproductive system of male fish; however, the effects of E2 on other aspects of fish metabolism, morphology and histopathological changes in internal organs are not well known. The objective of this study is to evaluate the effects of E2 exposure on the basal and stressed metabolic rate, morphological changes in body shapes, and histological changes in the liver tissues of sunfish species. Fish were held individually in ten gallon tanks under two treatments of 40 and 80 ng/L and …

Mutations In Dmrt3 Affect Locomotion In Horses And Spinal Circuit Function In Mice, Lisa S. Andersson, Martin Larhammar, Fatima Memic, Hanna Wootz, Doreen Schwochow, Carl-Johan Rubin, Kalicharan Patra, Thorvaldur Arnason, Lisbeth Wellbring, Göran Hjälm, Freyja Imsland, Jessica Lynn Petersen, Molly E. Mccue, James R. Mickelson, Gus Cothran, Nadav Ahituv, Lars Roepstorff, Sofia Mikko, Anna Vallstedt, Gabriella Lindgren, Leif Andersson, Klas Kullander

Department of Animal Science: Faculty Publications

Locomotion in mammals relies on a central pattern-generating circuitry of spinal interneurons established during development that coordinates limb movement. These networks produce left–right alternation of limbs as well as coordinated activation of flexor and extensor muscles. Here we show that a premature stop codon in the DMRT3 gene has a major effect on the pattern of locomotion in horses. The mutation is permissive for the ability to perform alternate gaits and has a favorable effect on harness racing performance. Examination of wild-type and Dmrt3-null mice demonstrates that Dmrt3 is expressed in the dI6 subdivision of spinal cord neurons, takes …

Observations On Relationships Between Limb Measurements And Mode Of Locomotion In Malaysian Turtles, Duayne Nyckel

Masters Theses

Twelve Genera (spanning three Families) of Malaysian Turtles were studied to determine whether bone lengths could be correlated to mode of locomotion. Ulna, humerus, tibia, femur, coracoid (among others) were measured and results were presented graphically. Five of the genera were observed singly in a large aquarium. Data were recorded on the amount of time each spent in different locomotor modes. Both limb length data and aquarium observations suggest that turtles can be grouped into three main locomotor habits (i.e. terrestrial walking, bottomwalking, and swimming). The terrestrial group includes the genera, Geochelone, Kinixys, and Gopherus. Bottomwalkers include …

A Survey Of Shearing Times, B R. Beetson

Journal of the Department of Agriculture, Western Australia, Series 4

When do farmers in W.A. shear their sheep, and why do they selest the times they do?

A Department of Agriculture survey attempted to answer these questions, which have important implications for the wool industry.

Seasonal Variation In The Tubular And Interstitial Areas Of The Testes In Sternotherus Odoratus L., Robert Hans Spaet

Masters Theses

Seasonal changes within the tubular and interstitial areas of the testes in Sternotherus odoratus are investigated, histologically and histochemically. Forty specimens were collected in Illinois, Tennessee and Louisiana between May, 1969 and August, 1972.

Many of the histological and macroscopic observations made by Risley (1938) on the spermatogenic cycle of S. odoratus in Michigan are confirmed. Contrary to his findings, fluctuations in interstitial cell nuclear diameters are observed during spermatogenesis. Greatest diameters coincide with what Risley has considered " . . . period of most active breeding." Sertoli cell nuclear diameters undergo similar fluctuations being greatest during spring breeding and …

A Study Of Thoracic Skeletomusculature In Peracarida (Crustacea), Donna R. Gill

Masters Theses

Two species of peracarid malacostracans, a mysid, Neomysis americana, and an oniscid isopod, Trachelipus cf. rathkei, were used to study the skeletomusculature system. Serial sections, whole mounts, and gross dissections were made. Coxal promotors and remotors and basal adductors and abductors were the muscle groups examined.

The promotor and remotor muscles of N. americana were found to be numerous, well developed, taking origin primarily from the dorsal thoracic wall, and extending nearly ventrally to insert in the coxa; the adductor muscle and two abductor muscles are weakly developed. The coxa in T. cf. rathkei is incorporated completely …

Basic Pig Breeding, P Mcnamara

Journal of the Department of Agriculture, Western Australia, Series 4

PROFITABLE pig raising depends on the tumoff of efficiently grown animals. Breeders should be selected for growth rate, and proper care of the breeding sow will ensure that her litters are large and healthy.

A rapid increase in the number of breeding sows in Western Australia suggests that some relatively inexperienced breeders may have started raising pigs. This article sets out the best pig breeding methods as a guide to beginners and a reminder to more experienced pig raisers.

Congenital Abnormalities In Sheep In Western Australia, Stanley M. Dennis

Journal of the Department of Agriculture, Western Australia, Series 4

IN every flock of sheep an abnormal or deformed lamb is seen from time to time.

But in some flocks in some years the incidence of these abnormal lambs is higher than usual.

Congenital Abnormalities In Sheep, Stanley M. Dennis

Journal of the Department of Agriculture, Western Australia, Series 4

More than 60 forms of abnormality have been found in lambs in Western Australia and in some flocks the proportion of particular abnormalities has been as high as 8 per cent, of lambs born.

In this article Dr. Dennis discusses the causes of abnormalities and reports progress of a Statewide survey of congenital abnormalities.

Ram Management, J Craig

Journal of the Department of Agriculture, Western Australia, Series 4

REALISING that good rams play an important role in flock improvement, the wise flock owner selects his rams after careful consideration of their breeding, type, production and fleece characters or potential meat-producing qualities.

Good ram management can have a major effect on lambing percentages. In this article Senior Veterinary Surgeon J. Craig outlines methods of achieving the best results from rams.

Teaser (Vasectomised) Rams : A Management Advantage, W L. Mcgarry, I. K. Stott

Journal of the Department of Agriculture, Western Australia, Series 4

WITH normal late spring-early summer matings (October-December) teaser rams, correctly used, will give a more concentrated lambing.

This has been shown under Western Australian conditions in trials conducted at the Wongan Hills Research Station.

In one experiment a group of 100 ewes which had one per cent, of teasers for 14 days before the fertile rams went in, dropped 42 lambs in the first two weeks of lambing, compared with 17 lambs from 100 ewes that were not teased.

The use of teasers in all Research Station flocks is now routine practice.

A Study Of The Renal Vascular Supply In The Domestic Cat, Elizabeth Rosen

Bachelors’ Theses

Studies on the normal and abnormal vascularization of the renal vessels in the domestic cat (felis domestica) indicate the frequency of anomalies that occur, but in most of the studies it is the inferior vena cava that is most often recorded. Among the occasional references to several renal veins or arteries we have Huntington and McClure, Elmer Butler, Gaylord Bates, William Darrach, and C.H. Fortune. Yet no study seems to have been made of individuals of any particular class. A superficial observation seems to indicate a large number of cats used in the laboratory had multiple renal veins. Hence a …

A Study Of The Digestive System In The Sparrow (Passer Domesticus), Henry Joseph Wisniewski

Bachelors’ Theses

The digestive tube proper of the Sparrow beings with the Oesophagus. This is a soft tubular organ which serves to convey food rapidly from the pharynx to the stomach. It extends along the median ventral margin of the neck lying dorsal to or to one side of the trachea. Posteriorly, at the base of the neck and shortly in front of the sternum it broadens slightly and gives rise to a dilated region of the oesophagus, namely the Crop, "whose secretion serves to moisten the food or even to initiate digestion." In larger birds as in the pigeon, the crop …

The Spinal Nerves And Spinal Cord Of The Frog, Laverne A. Penn

Bachelors’ Theses

The common grass frog, Rana pipiens as wall as the bull frog, Rana catesbiana have served during many decades as material from which both the student of zoology and the investigator in biological problems have gathered valuable information about the anatomy and physiology of the common systems. Among these systems the central, peripheral, and sympathetic nervous system plays a coordinating role, because of the ramifying nature of its organization. It is the purpose of this thesis to investigate the gross and histological structure of these branches known as spinal nerves. When one inspects the literature on the nervous system of …

The Muscles Of The Forelimb Of Canis Familiaris, Charles G. Wilber

Bachelors’ Theses

In the study of the anatomy of the vertebrates, there has been much work done and a large number of the forms have been studied with great thoroughness. Among the domesticated animals this is particularly true. The students of the veterinary sciences have given us a deep insight into the structure and function of the mammalian body. This is most certainly true in the case of the dog. The species Canis familiaris has been used for many years in the studies of physiology and surgery. However, it is also true that a plenitude of literature relative to the anatomy of …

The Anatomy Of The Oyster, M.J. Rohlinger

Bachelors’ Theses

The phylum Mollusca manifests the following characteristics: bilateral symmetry; three primary germ layers; free-living and sessile; marine and fresh-water; a shell modified to form either a bivalve or a univalve which gives an appearance of segmentation due to rings of growth or arrangement of certain parts of the shell as is seen in the class Amphineura, this is only apparent metamerism because the Mollusca are considered to be unsegmented animals; a coelom poorly developed; a foot; a mantle cavity; well developed digestive, circulatory, excretory, and reproductive systems. When one inspects a Chiton, an oyster, a snail, an octopus, or a …
