DIAGNOSTIC INVESTIGATION OF AMERICAN ROBINS () WITH FATAL ETHYLENE GLYCOL TOXICOSIS AND CONCURRENT SPP. INFECTION WITH RETROSPECTIVE REVIEW OF 44 YEARS OF DIAGNOSTIC DATA.

We describe a mortality event involving at least 44 adult American robins () that were found dead on the morning of February 25, 2023 in a residential backyard in Natchitoches Parish, Louisiana. Five carcasses were submitted for diagnostic evaluation. All five robins were in good nutritional and feather condition with no external indicators of injury or illness.

Transcranial photobiomodulation therapy improves cognitive test scores in dogs with presumptive canine cognitive dysfunction: A case series of five dogs.

Background: Canine cognitive dysfunction (CCD) is considered the canine version of human Alzheimer's disease (AD). As with AD, CCD is a multifactorial and progressive neurodegenerative disorder for which effective treatment options are continuously being sought. Transcranial photobiomodulation (tPBMT) or transcranial laser therapy has shown promise as a treatment for cognitive impairment in rodent AD investigations and several human AD clinical trials.

ASPIRE for excellence in student engagement: Examples of how institutions operationalize a complex construct.

Student engagement is a key contributor to educational programme quality. It is a complex construct often defined with the focus on student behaviors. However, a broader, more organizational approach takes into account the institutional context and how this can be structured to encourage and support students' willingness and ability to become engaged.

Cholangiocarcinoma with carcinomatosis in a sugar glider.

A 7-y-old, castrated male, leucistic sugar glider () was presented because of a progressive history of lethargy, ataxia, diarrhea, and anorexia. Abdominal ultrasound revealed fluid in the abdomen and an infiltrative mass in the liver. Due to a poor prognosis, euthanasia was performed.

Macropod Pediatrics.

Macropods belong to the marsupial family Macropodidae, which includes animals such as kangaroos and wallabies. Macropod offspring are highly altricial at birth and require specialized care and environmental conditions for healthy development. The care and management of pediatric macropods poses a challenge due to the unique physiology and reproductive strategy of macropods.

Naturally occurring histological findings and Alzheimer's-like pathology in the brain of aging African green monkeys (Chlorocebus sabaeus).

Nonhuman primates (NHPs) are important to study the pathophysiology of neurodegenerative disease and evaluate therapies targeting the central nervous system (CNS). Understanding the age-associated incidence of natural CNS pathology in a given NHP species is critical to assess the safety of potential treatments for neurodegenerative disorders like Alzheimer's disease (AD). We describe background and age-related neuropathology in the St.

Histology, prevalence, and environmental sources for pulmonary silicates depositions in domestic and wild animals.

The source and significance of pulmonary silicate crystals in animals and people are poorly understood. To estimate the prevalence and characterize the pulmonary crystalline material in animals from St. Kitts, tissue samples from dogs, horses, cattle, sheep, goats, pigs, chickens, mongooses, and monkeys were examined by light microscopy, scanning electron microscopy with energy-dispersive x-ray analysis (SEM/EDXA), and x-ray diffraction.

Changing Perspectives from Oxidative Stress to Redox Signaling-Extracellular Redox Control in Translational Medicine.

Extensive research has changed the understanding of oxidative stress that has been linked to every major disease. Today we distinguish oxidative eu- and distress, acknowledging that redox modifications are crucial for signal transduction in the form of specific thiol switches. Long underestimated, reactive species and redox proteins of the Thioredoxin (Trx) family are indeed essential for physiological processes.

Evaluation of hair and nail cortisol concentrations and associations with behavioral, physical, and environmental indicators of chronic stress in cats.

Background: Chronic stress is implicated in behavioral and health issues in cats, but methods for recognition, evaluation, and measurement of stress are lacking. Cortisol concentration is typically used as an indicator of stress.

Objectives: To evaluate use of an enzyme immunoassay to quantitate hair and nail cortisol concentrations (HCC and NCC) in cats and evaluate associations between HCC and NCC and behavioral, physical, and environmental correlates of chronic stress in cats.

An Effective Mouse Model of Unilateral Renal Ischemia-Reperfusion Injury.

Ischemia-reperfusion injury (IRI) is the leading cause of acute renal failure and is a significant contributor to delayed graft function. Animal models are the only available resources that mimic the complexities of the IRI-associated damage encountered in vivo. This paper describes an effective mouse model of unilateral renal IRI that delivers highly reproducible data.

Retrospective investigation of Echinococcus canadensis emergence in translocated elk (Cervus canadensis) in Tennessee, USA, and examination of canid definitive hosts.

Background: Few reports of Echinococcus spp. have been described in the USA; however, the geographical distribution of Echinococcus spp. in wild hosts is increasing consequent to human activities.
