The 5‐lipoxygenase inhibitor tepoxalin induces oxidative damage and altered PTEN status prior to apoptosis in canine osteosarcoma cell lines          下载免费PDF全文

J. P. Loftus  D. Cavatorta  J. J. Bushey  C. B. Levine  C. S. Sevier  J. J. Wakshlag 《Veterinary and comparative oncology》2016,14(2):e17-e30

The 5‐lipoxygenase (5‐LOX) inhibitor tepoxalin has been shown to slow canine osteosarcoma (OSA) tumour xenografts growth, yet the mechanisms are poorly elucidated. Further examination of tepoxalin in canine OSA cell lines shows that tepoxalin treated cells undergo apoptosis through caspase‐3 activation and annexin staining. Interestingly, apoptosis is superseded by an increase in reactive oxygen species (ROS), as measured by activation of dihydrorhodamine 123 and mitosox. This increase in ROS appears to be related to the 5‐LOX inhibitor regardless of cellular 5‐LOX status, and was not observed after treatment with the tepoxalin metabolite RWJ20142. Additionally, 5‐LOX inhibition by tepoxalin appears to increase phosphatase and tensin (PTEN) homolog activity by preventing its alkylation or oxidation. PTEN modification or inhibition allows phosphoinositide‐3 (PI3) kinase activity thereby heightening activation of protein kinase B (AKT) phosphorylation. Our data suggest that off target oxidation and LOX inhibition play roles in the apoptotic response.  相似文献   

A comparison of clinical,magnetic resonance imaging and pathological findings in dogs with gliomatosis cerebri,focusing on cases with minimal magnetic resonance imaging changes‡          下载免费PDF全文

R. T. Bentley  G. N. Burcham  H. G. Heng  J. M. Levine  R. Longshore  S. Carrera‐Justiz  K. Kopf  M. A. Miller 《Veterinary and comparative oncology》2016,14(3):318-330

The primary study objective was to determine whether clinical examination and magnetic resonance imaging (MRI) can underestimate canine gliomatosis cerebri (GC); we also investigated immunohistochemical features. Seven dogs with GC were studied; four recruited specifically because of minimal MRI changes. Neuroanatomic localization and the distribution of MRI, gross and sub‐gross lesions were compared with the actual histological distribution of neoplastic cells. In six cases, clinical examination predicted focal disease and MRI demonstrated a single lesion or appeared normal. Neoplastic cells infiltrated many regions deemed normal by clinical examination and MRI, and were Olig2‐positive and glial fibrillary acid protein‐negative. Four dogs had concurrent gliomas. GC is a differential diagnosis for dogs with focal neurological deficits and a normal MRI or a focal MRI lesion. Canine GC is probably mainly oligodendrocytic. Type II GC, a solid glioma accompanying diffuse central nervous system neoplastic infiltration, occurs in dogs as in people.  相似文献

Theory of mind is independent of episodic memory     

Rosenbaum RS  Stuss DT  Levine B  Tulving E 《Science (New York, N.Y.)》2007,318(5854):1257

Theory of mind (ToM) to infer other people's current mental states and episodic memory of personal happenings have been assumed to be closely related. We report two participants with severely impaired episodic memory who perform indistinguishably from healthy controls on objective ToM tests. These results suggest that ToM can function independently of episodic memory.  相似文献   

Suspected panosteitis in a camel     

Levine DG  Smith JJ  Richardson DW  Brown V  Beech J  Habecker P  Adam E 《Journal of the American Veterinary Medical Association》2007,231(3):437-441

CASE DESCRIPTION: A 6-month-old male Bactrian camel was examined because of a 3-week history of lameness of the left hind limb. CLINICAL FINDINGS: Lameness was initially detected in the left hind limb but resolved and was detected in the right hind limb during treatment. Lameness increased during periods of rapid growth. Radiography revealed multiple small opacities of the medullary cavity of several long bones throughout treatment. Core bone biopsies of lesions in the tibiae revealed lamellar bone with areas of loose connective tissue, osteoblasts in the medullary cavity, and periosteal new bone formation, all which were consistent with panosteitis. TREATMENT AND OUTCOME: Palliative treatment was attempted with epidural and transdermal administration of analgesics. Flunixin meglumine was administered PO, which coincided with an abrupt increase in serum creatinine concentration. Performance of multiple diagnostic bone biopsies led to remission of clinical signs of pain. CLINICAL RELEVANCE: Panosteitis should be a differential diagnosis for shifting limb lameness in young camels. Bone biopsies can be useful for diagnosis of panosteitis and possible relief of pain associated with the disease. Bactrian camels may be susceptible to the renal toxicity of flunixin meglumine, especially when dehydrated.  相似文献   

Requirements for the successful introduction and management of rotational irrigation     

G. Levine  L. T. Chin  S. M. Miranda 《Agricultural Water Management》1976,1(1):41-56

This paper attempts to identify the critical elements associated with the introduction and management of the practice of Rotational Irrigation in Taiwan, and thus to shed some light on the basic requirements for its successful adoption. While the emphasis is on this specific practice we believe it has implications for the transfer of other technologies in which physical, biological and managerial factors interact importantly.Seven irrigation associations in Taiwan were studied to identify the external conditions and system characteristics that are necessary for a successful change from continuous to rotational irrigation. Three external essentials are identified: (1) a water deficit approximating 25 percent of normal practice in the area; (2) political commitment to the change; (3) adequate financial resources for implementation and subsequent operation. Two system characteristics considered essential are: (1) physical facilities that provide for control and measurement to the level of farmer group responsibility; and (2) management patterns that provide a well-organized operating group and effective communication between the farmers and system personnel, resulting in a responsive plan of operation.Specific adaptations of the Taiwan practices to the local conditions will be necessary before effective transfer of this technology can take place elsewhere.  相似文献   

Introduction to veterinary physical rehabilitation.     

David Levine  Darryl L Millis  Denis J Marcellin-Little 《Veterinary Clinics of North America: Small Animal Practice》2005,35(6):1247-54, vii

Physical therapy is a profession with an established scientific basis in human beings and companion animals. It has a large number of clinical applications in the restoration, maintenance, and promotion of optimal physical function. In providing physical therapy, the goal is to restore, maintain, and promote optimal function, optimal fitness, wellness, and quality of life as they relate to movement disorders and health. A major emphasis is to prevent or minimize the onset, clinical signs, and progression of impairments, functional limitations, and disabilities that may result from diseases, disorders, conditions, and injuries.  相似文献

The purpose of this article is to review the use of cold, heat, therapeutic ultrasound, and electrical stimulation in small animal rehabilitation.The material in this article is a compilation from the veterinary and hu-man literature. Additional information is needed on how to adapt the techniques used in human beings to small animals and then to establish the efficacy of these techniques in animals.  相似文献
