Veterinary Clinical Teaching
The aim of clinical teaching in veterinary medicine is preparing graduates to meet all required veterinary graduate attributes. The veterinary learner needs to understand the various potential constraints in their clinical education. In addition to government and professional regulations, the animal and their welfare are essential considerations, as is the impact of food animal clinical practice on food safety. Indeed, the environmental considerations around repercussions of veterinary products (e.g., diclofenac and the Asian Vulture Crisis) parallel food safety and welfare.

Veterinary Antiparasitic to Human Anticancer
Cancer is an extensive disease and the most common cause of morbidity and mortality worldwide. It is characterized by a deregulation of the cell cycle, which primarily results in a progressive loss of control of cellular growth and differentiation. The repurposing of veterinary antiparasitic drugs for the treatment of cancer is gaining traction, as supported by existing literature. A prominent example is the proposal to implement the use of veterinary antiparasitics such as benzimidazole carbamates and halogenated salicylanilides as novel anticancer drugs. These agents have revealed pronounced anti-tumor activities and gained special attention for “double repositioning”, as they are repurposed for different species and diseases simultaneously, acting via different mechanisms depending on their target. As anticancer agents, these compounds employ several mechanisms, including the inhibition of oncogenic signal transduction pathways of mitochondrial respiration and the inhibition of cellular stress responses.

Veterinarians as Animal Welfare Experts
Veterinarians are animal health experts, and they have been conferred a leading role as experts in animal welfare. This expectation of veterinarians as welfare experts appears to stem from their training in veterinary medicine as well as professional contributions to welfare-relevant policy and law. Veterinarians are ideally situated to act as animal welfare experts by virtue of their core work with animals and potential influence over owners, their roles in policy development, compliance, and monitoring, and as educators of future veterinarians.

Vestigiality
Vestigiality is the retention during the process of evolution of genetically determined structures or attributes that have lost some or all of the ancestral function in a given species. Assessment of the vestigiality must generally rely on comparison with homologous features in related species. The emergence of vestigiality occurs by normal evolutionary processes, typically by loss of function of a feature that is no longer subject to positive selection pressures when it loses its value in a changing environment. The feature may be selected against more urgently when its function becomes definitively harmful, but if the lack of the feature provides no advantage, and its presence provides no disadvantage, the feature may not be phased out by natural selection and persist across species. Examples of vestigial structures (also called degenerate, atrophied, or rudimentary organs) are the loss of functional wings in island-dwelling birds; the human vomeronasal organ; and the hindlimbs of the snake and whale. The human appendix is no longer considered vestigial.

Vestibular Schwannoma for Hearing Preservation Surgery
Vestibular schwannoma is a clinically benign schwannoma that arises from the vestibulocochlear nerve that causes sensorineural hearing loss. This tumor is clinically and oncologically regarded as a benign tumor as it does not metastasize or invade surrounding tissues. Despite being a benign tumor, its management is difficult and controversial due to the potential serious complications, such as irreversible sensorineural hearing loss, of the interventions. Therefore, preventing hearing loss due to the natural course of the disease and complications of surgery is a challenging issue for an otologist.

Vestibular Assessment and Rehabilitation in the Operational Environment
The vestibular system, comprised of the semicircular canals, otolith organs, and eighth cranial nerves in the peripheral system, and the brainstem, brain, and cerebellum in the central system, is essential for gaze and postural stability. It allows service members to keep their eyes fixed on a target while their head is moving, and additionally contributes to the maintenance of balance. Evaluation of the vestibular system requires a systematic assessment of the visual, vestibular, and balance systems; technology can aid in this assessment. While technology can assist physical and occupational therapists in performing vestibular assessment and rehabilitation, not all such technologies are conducive to delivery of healthcare in an operational environment. In this context, the environment is characterized by the presence of extreme conditions and constrained resource availability.

Vestiarium Scoticum
The Vestiarium Scoticum (full title, Vestiarium Scoticum: from the Manuscript formerly in the Library of the Scots College at Douay. With an Introduction and Notes, by John Sobieski Stuart) was first published by William Tait of Edinburgh in a limited edition in 1842. John Telfer Dunbar, in his seminal work History of Highland Dress referred to it as "probably the most controversial costume book ever written." The book itself purported to be a reproduction, with color ilustrations, of an ancient manuscript on the clan tartans of Scottish families. Shortly after its publication, it was denounced as a forgery and the "Stuart" brothers who brought it forth, and who claimed to be the grandsons of Bonnie Prince Charlie himself, were likewise denounced as imposters. It is generally accepted today that both the brothers and the Vestiarium are indeed inauthentic. Nevertheless, the role of the book in the history of Scottish tartans is immense, with many of the designs and patterns contained therein passing into the realm of official clan tartans.

Vested Interest (Communication Theory)
Vested interest (Crano, 1983; Crano & Prislin, 1995; Sivacek & Crano, 1982) is a communication theory that seeks to explain how certain hedonically relevant (Miller & Averbeck, 2013) attitudinal dimensions can influence and consistently predict behavior based on the degree of subjective investment an individual has in a particular attitude object. As defined by William Crano, vested interest refers to the degree to which an attitude object is deemed hedonically relevant by the attitude holder. According to Crano, "an attitude object that has important perceived personal consequences for the individual will be perceived as highly vested. Highly vested attitudes will be functionally related to behavior" (Crano, 1983). Simply put, when people have more at stake with the result of an object (like a law or policy) that will greatly affect them, they will behave in a way that will directly support or defy the object for the sake of their own self-interest. For example, a 30-year-old learns that the legal driving age in his state is being raised from 16 to 17. While he may not agree with this proposed change, he is not affected as much as a 15-year-old would be and is unlikely to protest the change. A 15-year-old, however, has much to lose (waiting another year to get a driver license) and is more likely to vehemently oppose the new proposed law. To gather support for his position, a course of action the 15-year-old might take would be to tell other soon-to-be drivers about the new law, so that they collectively have a vested interest in perhaps changing the law. This example illustrates the point that highly vested attitudes concerning issues depend on the individual's point of view. Another example of vested interest can be found in a study conducted by Berndsen, Spears and van der Pligt, which involves students from a University in Amsterdam where the teaching faculty proposed the use of English to teach the curriculum instead of Dutch. Vested interest, in this case, suggests that students would be opposed to the use of English rather than Dutch simply based on the potential impact lectures conducted in English might have on their grades.

Vessel Wall Magnetic Resonance Imaging in Cerebrovascular Diseases
Cerebrovascular diseases are a leading cause of disability and death worldwide. The definition of stroke etiology is mandatory to predict outcome and guide therapeutic decisions. The diagnosis of pathological processes involving intracranial arteries is especially challenging, and the visualization of intracranial arteries’ vessel walls is not possible with routine imaging techniques. Vessel wall magnetic resonance imaging (VW-MRI) uses high-resolution, multiparametric MRI sequences to directly visualize intracranial arteries walls and their pathological alterations, allowing a better characterization of their pathology. VW-MRI demonstrated a wide range of clinical applications in acute cerebrovascular disease. Above all, it can be of great utility in the differential diagnosis of atherosclerotic and non-atherosclerotic intracranial vasculopathies. Additionally, it can be useful in the risk stratification of intracranial atherosclerotic lesions and to assess the risk of rupture of intracranial aneurysms. Recent advances in MRI technology made it more available, but larger studies are still needed to maximize its use in daily clinical practice.
