Mixed germ cell tumors of the ovary have rarely been reported in veterinary species. A 3-year-old intact female Labrador Retriever dog was presented for lethargy, abdominal distention, and a midabdominal mass. An exploratory laparotomy revealed a large (23 cm in diameter) left ovarian tumor and multiple small (2-3 cm in diameter) pale tan masses on the peritoneum and abdominal surface of the diaphragm. Histological examination of the left ovary revealed a mixed germ cell tumor with a yolk sac component with rare Schiller-Duval bodies and a teratomatous component comprised primarily of neural differentiation. The abdominal metastases were solely comprised of the yolk sac component. The yolk sac component was diffusely immunopositive for cytokeratin with scattered cells reactive for α-fetoprotein and placental alkaline phosphatase. Within the teratomatous component, the neuropil was diffusely immunopositive for S100, neuron-specific enolase, and neurofilaments with a few glial fibrillary acidic protein immunopositive cells. Ovarian germ cell tumors may be pure and consist of only 1 germ cell element or may be mixed and include more than 1 germ cell element, such as teratoma and yolk sac tumor.

Telemedicine in veterinary practice.

Veterinary surgeons have a long tradition of consulting one another about problem cases and many have unwittingly practised telemedicine when discussing cases by telephone or by sending laboratory reports by telefax. Specific veterinary telemedicine applications have been in use since the early 1980s, but little research has been undertaken in this field. The Pubmed and CAB International databases were searched for the following Boolean logic-linked keywords; veterinary and telemedicine, veterinary and telecare, animal and telemedicine, animal and telecare and veterinary and e-mail and an additional search was made of the worldwide web, using Google Scholar. This returned 25 papers which were reviewed. Of these only 2 report research. Sixteen papers had no references and 1 author was associated with 13 papers. Several themes emerge in the papers reviewed. These include remarks about the use of telemedicine, the benefits that can and are derived from the use of telemedicine, areas of practice in which telemedicine is being used, ethical and legal issues around the practice of telemedicine, image standards required for telemedicine, the equipment that is required for the practice of telemedicine, advice on ways in which digital images can be obtained and educational aspects of telemedicine. These are discussed. Veterinary practice has lagged behind its human counterpart in producing research on the validity and efficacy of telemedicine. This is an important field which requires further research.

There is ongoing debate in the profession as to whether veterinary students should focus on one (or a small number of) species during their undergraduate training (ie, track). This paper presents the qualitative data from surveys evaluating UK stakeholder opinion on introducing partial tracking (whereby students continue to qualify able to practise in all species) and full tracking (students qualify in a limited number of species with restricted registration). Surveys were distributed to practitioners, students and university staff; 1061 responses were completed. Thematic framework analysis was conducted on the free-text responses; responses were coded to a hierarchical framework developed inductively from the data. Six major themes were identified: choice, flexibility, competency and knowledge, stakeholder implications, specialisation and 'what is a vet?'. The majority of the themes related to both full and partial tracking, usually being more pronounced in full tracking. The theme 'choice' is particularly important in light of the study's quantitative findings on students' awareness of the profession and their career aspirations (presented in a previous paper); should tracking be implemented, veterinary schools will need to take a proactive role in educating and assisting students while making career choices.

To report the signalment, clinical presentation, treatments pursued and outcomes of dogs with malignant anal sac melanoma. Medical records from five institutions from January 2000 through December 2015 were reviewed and dogs with cytologically- or histologically-confirmed malignant anal sac melanoma were identified. Signalment, clinical signs, staging, cytology, histopathologic analysis, surgical and non-surgical treatments were extracted from the medical records. The referring veterinarians and owners were contacted for follow-up data. Eleven dogs were included and survival data was available for all. The most common clinical signs were bloody anal sac discharge and perianal licking. Initial treatments pursued included surgery (n=8), chemotherapy (n=1), and palliative treatment with pain medications and stool softeners (n=2). In an adjuvant setting, melanoma vaccine was pursued following surgery in three dogs and chemotherapy in one dog. Regardless of treatment, progression-free survival (mean 92 · 5 days) and overall survival times (median 107 days) were short. Dogs in this case series had a guarded to poor prognosis regardless of treatment. Ten of 11 dogs were euthanased due to local or distant disease progression. Only 1 of 11 dogs was alive one year after diagnosis. An understanding of tumour behaviour in this location could lead to improved survival times with earlier diagnosis and treatment. © 2017 British Small Animal Veterinary Association.

The electrochemical migration (ECM) behaviour of SAC 305, SAC 0307 and SAC 0307-0.03 P-0.005 Ni has been investigated by using simulated body fluid (SBF) solution. Water drop test (WDT) was performed to compute the mean-time-to-failure (MTTF) of each sample while its electrical behaviour was examined using four-point probe test station. The microstructure of each solder paste alloy was observed using field emission scanning electron microscope (FESEM) with energy dispersive X-ray spectroscopy (EDX) to analyse the elemental composition of the solder alloy. The MTTF result shows that SAC 305 has the fastest time-to-failure (TTF) due to short circuit. The corrosion susceptibility of SAC 305 was higher compared with SAC 0307-0.03P-0.005Ni. This was because of the influence of dopant phosphorus and nickel incorporation in the SAC 0307-0.03 P-0.005 Ni. The four point-probe test station reveals that SAC 305 is a good electric conductor whilst SAC 0307-0.03 P-0.005 Ni is a poor electric conductor. The rate of dendritic growth was influenced by the alloying element of the solder. Therefore, SAC 0307-0.03 P-0.005 Ni have a good corrosion resistance in SBF medium.

Evidence from human medicine shows a rise in telephone communication in support of after-hours services and in providing medical advice, follow-up information, etc. While specific training programs are continuously being developed for human medical education, limited publications are available on training veterinary students in telephone communication. Presented is our method of introducing a telephone communication skills exercise to third-year veterinary students. The exercise progressed over three phases and currently follows the principles of the Calgary-Cambridge Guide. Challenges and improvements on implementing a telephone communication exercise are discussed. Within veterinary communication curricula, attention should be given to the specific communication skills required for successful telephone consultations. In the absence of visual nonverbal cues and prompts during a telephone interaction, communication skills must be applied with greater intent and attention to achieve an effective consultation outcome.

A 10-year-old intact female Shetland Sheepdog with tenesmus had a subcutaneous mass at the left ventral aspect of the anus. On cytologic examination, 2 types of cells were observed. Most of the cells were oval to polygonal and had elliptical or elongate nuclei and a moderate amount of pale to basophilic cytoplasm. The remaining cells had round to oval nuclei and pale to basophilic cytoplasm. Cells of both types were loosely adhered to each other and were arranged in rosette-like structures. Both neoplastic cell types had fine homogenous chromatin and either a small indistinct nucleolus or no visible nucleolus. Mild anisokaryosis and anisocytosis were observed. Histologically, the mass consists of glandular structures formed by cuboidal cells admixed with bundles of spindle cells. Eosinophilic PAS- and Alcian blue-positive secretory material was found in the center of some glandular structures. Both neoplastic cell types had positive staining with paradoxical concanavalin A and expressed cytokeratin, but not vimentin, S-100, α-smooth muscle actin, or desmin. Based on location and histologic and immunohistochemical features, the final diagnosis was adenocarcinoma of the apocrine gland of the anal sac, which should be included as a cytologic differential diagnosis when spindle cells and typical epithelial cells are observed in masses in the region of the anal sac of dogs. © 2012 American Society for Veterinary Clinical Pathology.

To report the outcomes and complications of a cohort of dogs with primary and recurrent anal sac adenocarcinoma managed with surgery as the first-line treatment. To report the use of lymph node cytology for identification of metastatic disease. Retrospective review of case records of a single referral centre population of dogs diagnosed with anal sac adenocarcinoma. Fifty-two clinical cases were identified. Altered ultrasonographic appearance of lymph nodes was highly consistent with metastatic disease as assessed by cytology and histopathology. Seven of 58 (12%) perineal surgeries had reported minor complications and seven (12%) others required further surgical intervention. Minor controllable intraoperative bleeding was the only complication noted associated with lymph node extirpation in two of 39 (5%) metastectomy procedures. Six dogs (12%) suffered local recurrence and 22 (42%) developed subsequent or recurrent nodal metastatic disease. From the time of detection of disease recurrence, median additional survival associated with a second surgical intervention was 283 days. Coeliotomy for lymph node metastatectomy in dogs with adenocarcinoma of the anal sac has low morbidity and should be considered in patients presenting with evidence of regional metastatic disease both at initial presentation and with recurrent disease. © 2017 British Small Animal Veterinary Association.

Patients Without Borders: Using Telehealth to Provide an International Experience in Veterinary Global Health for Veterinary Students.

Mazan, Melissa R; Kay, Gigi; Souhail, Mohammed Larbi; Bubeck, Kirstin; Jenei, Thomas; Merriam, Jay

There is an increasing need to produce veterinarians with knowledge and critical thinking skills that will allow them to participate in veterinary global health equity delivery, particularly in the developing world, where many people remain dependent on animal-based agriculture for a living. This need for veterinarians trained in global health is reflected by the demand among students for greater exposure and education. At the same time, many students are held back from on-site training in global health due to constraints of cost, time, or family obligations. The purpose of this article is to describe the use of a telemedicine approach to educating veterinary students at Tufts Cummings School of Veterinary Medicine. This approach simultaneously provides expert consultation and support for a pro bono hospital in the developing world. The development of a telemedicine teaching service is discussed, from initial ad hoc email consultation among friends and associates to a more formal use of store-and-forward delivery of data along with real-time videoconferencing on a regular basis, termed tele-rounds. The practicalities of data delivery and exchange and best use of available bandwidth are also discussed, as this very mundane information is critical to efficient and useful tele-rounds. Students are able to participate in discussion of cases that they would never see in their usual clinical sphere and to become familiar with diagnostic and treatment approaches to these cases. By having the patient "virtually" brought to us, tele-rounds also decrease the usual carbon footprint of global health delivery.

The benign lesions of the lacrimal sac are very rare. The most typical epithelial tumor is squamous papilloma. This tumors often present with symptoms of dacryostenosis and dacriocystitis. Human papillomavirus (HPV) infection is known to be causative agent in the development of epithelial tumor. Lacrimal sac tumors could transform to malignant neoplasms, especially if they are developed of coexisting HPV infection. We present a patient with a squamous papilloma of the lacrimal sac and discussed the method of treatment. The patient was suffered from epiphora and recurrent dacriocystitis. An endoscopic surgery with dacriocystorhinostomy and local resection of the tumor could be an effective method of choice. The usage of a shaver for wide removal of the lacrimal sac wall is recommended to prevent local recurrence. The histopathology examination showed squamous papilloma. The patient is free of the disease over 8 months of follow up. Primary lacrimal sac papilloma require long term follow up for recurrence or malignant transformation. HPV infection could be associated with the development of lacrimal sac papillomas. Copyright © 2012 Polish Otorhinolaryngology - Head and Neck Surgery Society.

A 12-year-old male neutered Siamese cat presented with a history of inappetance and lethargy and an enlarged left anal sac. The anal sac was surgically excised and histopathology confirmed the diagnosis of anal sac adenocarcinoma. Perianal tumours are rare in the cat and anal sac adenocarcinoma has not been previously reported. This is in contrast to the dog where anal sac adenocarcinoma is a well recognised albeit uncommon tumour.

It is currently unclear how frequently a diagnosis is made during small-animal consultations or how much of a role making a diagnosis plays in veterinary decision-making. Understanding more about the diagnostic process will help direct future research towards areas relevant to practicing veterinary surgeons. The aim of this study was to determine the frequency with which a diagnosis was made, classify the types of diagnosis made (and the factors influencing these) and determine which specific diagnoses were made for health problems discussed during small-animal consultations. Data were gathered during real-time direct observation of small-animal consultations in eight practices in the United Kingdom. Data collected included characteristics of the consultation (e.g. consultation type), patient (e.g. breed), and each problem discussed (e.g. new or pre-existing problem). Each problem discussed was classified into one of the following diagnosis types: definitive; working; presumed; open; previous. A three-level multivariable logistic-regression model was developed, with problem (Level 1) nested within patient (Level 2) nested within consulting veterinary surgeon (Level 3). Problems without a previous diagnosis, in cats and dogs only, were included in the model, which had a binary outcome variable of definitive diagnosis versus no definitive diagnosis. Data were recorded for 1901 animals presented, and data on diagnosis were gathered for 3192 health problems. Previous diagnoses were the most common diagnosis type (n=1116/3192; 35.0%), followed by open (n=868/3192; 27.2%) then definitive (n=660/3192; 20.7%). The variables remaining in the final model were patient age, problem history, consultation type, who raised the problem, and body system affected. New problems, problems in younger animals, and problems raised by the veterinary surgeon were more likely to result in a definitive diagnosis than pre-existing problems, problems in older animals, and problems raised by

To assess the attitude of dairy farm consultants to the role of veterinarians on dairy farms and whether they viewed veterinary advice as impartial, free from commercial bias and central to farm productivity and profitability. A telephone survey was commissioned in September 2014 of 36 full-time farm consultants in the Canterbury and Otago region of New Zealand using a pre-prepared questionnaire to explore their attitudes towards the veterinary profession. Of those approached, 25 completed the survey. The consultants surveyed agreed or strongly agreed (21/23) that they were the custodians of animal health expenditure on farms, which was seen as an expense to be controlled (19/25 agreed or strongly agreed). This view was held more strongly (9/9 agreed or strongly agreed) by consultants with >5 years' professional experience, compared to 10/16 consultants with ≤5 years' experience. Most consultants (24/25) disagreed that they did not respect veterinary advice, but agreed (24/25) that veterinarians almost always had a vested interest in the advice that they gave. The role of veterinarians was seen by respondents to be mainly treatment of sick animals (22/25) and provision of animal health products (24/25), but not in maximising farm profitability (selected by 8/25 respondents). Consultants viewed their own roles as providing advice on the influence of animal health on farm profitability (21/25), nutrition (22/25) and reproduction (20/25). Most respondents (21/25) stated that reducing disease and animal health issues was important, but they (21/25) also identified a reduction in farm animal health expenditure as a measure of success. Only 7/25 consultants felt that they should work in partnership with veterinarians. This was a small scale study from one region of New Zealand but it indicates that consultants are ambivalent about the role and value of working more closely with veterinarians, and about the benefit that veterinary intervention may bring to a farm

Sentinel lymph node mapping can help to direct surgical oncologic staging and metastatic disease detection in patients with complex lymphatic pathways. We hypothesized that indirect computed tomographic lymphography (ICTL) with a water-soluble iodinated contrast agent would successfully map lymphatic pathways of the iliosacral lymphatic center in dogs with anal sac gland carcinoma, providing a potential preoperative method for iliosacral sentinel lymph node identification in dogs. Thirteen adult dogs diagnosed with anal sac gland carcinoma were enrolled in this prospective, pilot study, and ICTL was performed via peritumoral contrast injection with serial caudal abdominal computed tomography scans for iliosacral sentinel lymph node identification. Technical and descriptive details for ICTL were recorded, including patient positioning, total contrast injection volume, timing of contrast visualization, and sentinel lymph nodes and lymphatic pathways identified. Indirect CT lymphography identified lymphatic pathways and sentinel lymph nodes in 12/13 cases (92%). Identified sentinel lymph nodes were ipsilateral to the anal sac gland carcinoma in 8/12 and contralateral to the anal sac gland carcinoma in 4/12 cases. Sacral, internal iliac, and medial iliac lymph nodes were identified as sentinel lymph nodes, and patterns were widely variable. Patient positioning and timing of imaging may impact successful sentinel lymph node identification. Positioning in supported sternal recumbency is recommended. Results indicate that ICTL may be a feasible technique for sentinel lymph node identification in dogs with anal sac gland carcinoma and offer preliminary data to drive further investigation of iliosacral lymphatic metastatic patterns using ICTL and sentinel lymph node biopsy. © 2017 American College of Veterinary Radiology.

Scientific decision-making and stakeholder consultations: the case of salt recommendations.

Scientific advisory committees (SACs) are seen as "boundary organisations" working at the interface between science, policy and society. Although their narrowly defined remit of risk assessment is anchored in notions of rationality, objectivity, and reason, in reality, their sources for developing recommendations are not limited to scientific evidence. There is a growing expectation to involve non-scientific sources of information in the formation of knowledge, including the expectation of stakeholder consultation in forming recommendations. Such a move towards "democratisation" of scientific processes of decision-making within SACs has been described and often studied as "post-normal science" (PNS) (Funtowicz & Ravetz, 1993). In the current paper we examine the application of PNS in practice through a study of stakeholder consultations within the workings of the UK Scientific Advisory Committee for Nutrition (SACN). We use the theoretical insights from PNS-related studies to structure the analysis and examine the way in which PNS tenets resonate with the practices of SACN. We have selected a particular case of the SACN UK recommendations for salt as it is characterized by scientific controversy, uncertainty, vested interests and value conflict. We apply the tenets of PNS through documentary analysis of the SACN Salt Subgroup (SSG) consultation documents published in 2002/2003: the minutes of the 5 SACN SSG's meetings which included summary of the SACN SSG's stakeholder consultation and the SSG's responses to the consultation. The analysis suggests that the SACN consultation can be construed as a process of managing sources of risk to its organisation. Thus, rather than being an evidence of post-normal scientific practice, engagement became a mechanism for confirming the specific framing of science that is resonant with technocratic models of science holding authority over the facts. The implications for PNS theory are discussed. Copyright © 2013 Elsevier Ltd. All

Clinically Prepared Veterinary Students: Enhancing Veterinary Student Hands-on Experiences and Supporting Hospital Caseload Using Shelter Medicine Program.

Referral-level medicine is important in the veterinary curriculum, however veterinary students also need a solid base knowledge of clinically relevant, routine surgical and diagnostic skills to be clinically prepared after graduation. Exposure to a referral-only, or primarily referral caseload, does not always provide veterinary students with the routine hands-on experiences and competencies expected by the American Veterinary Medical Association Council on Education, the Royal College of Veterinary Surgeons, the Australian Veterinary Boards Council, or prospective employers. The aim of this descriptive study was to assess how a shelter medicine program can fill the companion animal caseload gap and create the necessary hands-on experiences considered essential in the veterinary curriculum. Pedagogical frameworks, course curriculum and design, student experiences, and student assessments were described for three core curricular areas (surgery, medical days, population medicine) of the Shelter Medicine Program at Mississippi State University. The shelter surgery experience provided a high-quality, high-volume spay/neuter environment where fourth-year students averaged 65 sterilization surgeries in two weeks and demonstrated a quantifiable decrease in surgical time. The shelter surgery experience added on average 9,000 small animal cases per year to the overall hospital caseload. Shelter medical days, where students provide veterinary care during on-site shelter visits, created opportunities for third-year students to directly interact with shelter animals by performing physical examinations and diagnostic testing, and to gain experience in developing treatment protocols and recommendations for commonly encountered problems. The shelter medical days experience averaged over 700 small animal cases per year and over 1,500 diagnostic procedures. Finally, students participated in 15 onsite shelter consultations where they obtained a working knowledge of biosecurity at a

Randomized prospective single-blinded placebo-controlled study. Tertiary center. Patients with Menière's disease with poorly controlled vertigo despite medical therapy and serviceable hearing that were offered ELSD. Patients randomized into two groups, with control group (n = 17) undergone ELSD without steroid injection and experimental group undergone ELSD with steroid injection (n = 18) MAIN OUTCOME MEASURE(S):: Audiogram, dizziness handicap inventory, tinnitus handicap inventory, frequency of vertigo spells, functional level scale, and quality of life were obtained at multiple intervals from preoperatively to 24 months postoperatively. ELSD resulted in a statistically significant improvement in vertigo control whether or not steroid was injected into the endolymphatic sac at the time of surgery. However, no additional benefit was observed with the addition of intra-sac steroid injection. No statistical difference in pure-tone average, tinnitus handicap inventory, dizziness handicap inventory, or quality of life was observed between the steroid and nonsteroid surgical groups up to 24 months postoperatively. ELSD is an effective treatment for Menière's disease refractory to medical therapy; however, the addition of intra-sac steroid injection at the time of surgery does not seem to result in a further improvement in patient outcomes.

Recrystallization Behavior in SAC305 and SAC305 + 3.0POSS Solder Joints Under Thermal Shock

2018-04-01

Sn-3.0Ag-0.5Cu (SAC305) and SAC305 + 3.0 polyhedral oligomeric silsesquioxanes (POSS) ball grid array (BGA) assemblies have been prepared, observed, and subjected to thermal shock. The microstructure and grain orientation evolution of the solder joints located at the same position of the package were characterized by scanning electron microscopy and electron backscattering diffraction, respectively. The results showed that the microstructure of the solder joints was refined by addition of POSS particles. In addition, compared with the single-grained or tricrystal joints normally observed in SAC305 BGA solder joints, the frequency of single-grained as-reflowed SAC305 + 3.0POSS BGA joints was greatly reduced, and the solder joints were typically composed of multicrystals with orientations separated by high-angle grain boundaries. These multicrystal joints appear to be obtained by dominant tricrystals or double tricrystals with deviation of the preferred [110] and [1\\bar{1}0] growth directions of Sn dendrites in Sn-Ag-based solder alloys during solidification from the melt. After 928 thermal shock cycles, the SAC305 solder joint had large-area recrystallization and cracks in contrast to the SAC305 + 3.0POSS solder joint located at the same position of the package, indicating that addition of POSS to SAC305 solder joints may contribute to postponement of recrystallization and subsequent crack initiation and propagation along recrystallized grain boundaries by pinning grain boundaries and movement of dislocations. This finding also confirms the double tricrystal solidification twinning nucleation behavior in Pb-free solder joints.

COX-2 expression in canine anal sac adenocarcinomas and in non-neoplastic canine anal sacs.

Anal sac adenocarcinoma (ASAC) is a clinically significant canine neoplasm characterized by early lymphatic invasion. Up-regulation of cyclooxygenase isoform 2 (COX-2) has been confirmed in several animal and human neoplastic tissues. The aim of the current study was primarily to evaluate COX-2 expression in canine ASAC and compare it to COX-2 expression in non-neoplastic canine anal sac tissue using immunohistochemistry with scoring for percentage positivity and intensity. Twenty-five ASAC samples and 22 normal anal sacs were available for evaluation. All canine ASAC samples and the normal anal sac tissues stained positively for COX-2. However, while normal anal sac tissue showed strong staining of the ductal epithelial cells, ASAC samples showed staining of the neoplastic glandular epithelial cells, with varying percentage positivity and intensity between ASAC samples. COX-2 immunoreactivity of ASAC samples was of low intensity in 52% and high in 12% of the cases; the remaining samples were of intermediate intensity. Seventy-six per cent of the ASAC had over 50% of the neoplastic glandular cells staining positive. These results confirm that COX-2 is expressed in the neoplastic glandular epithelial cells in canine ASAC and suggest a potential role for COX-2 inhibitors in the management of ASAC. Furthermore, the results indicate that COX-2 is expressed in ductal epithelial cells of the normal anal sac. Copyright © 2013 Elsevier Ltd. All rights reserved.

Efficacy of Several Pesticide Products on Brown Widow Spider (Araneae: Theridiidae) Egg Sacs and Their Penetration Through the Egg Sac Silk.

Information on pesticide effects on spiders is less common than for insects; similar information for spider egg sacs is scarcer in the open literature. Spider egg sacs are typically covered with a protective silk layer. When pesticides are directly applied to egg sacs, the silk might prevent active ingredients from reaching the eggs, blocking their insecticidal effect. We investigated the impact of six water-based pesticide sprays and four oil-based aerosol products against egg sacs of brown widow spiders, Latrodectus geometricus C. L. Koch. All water-based spray products except one failed to provide significant mortality to egg sacs, resulting in successful spiderling emergence from treated egg sacs at a similar rate to untreated egg sacs. In contrast to water-based sprays, oil-based aerosols provided almost complete control, with 94-100% prevention of spiderling emergence. Penetration studies using colored pesticide products indicated that oil-based aerosols were significantly more effective in penetrating egg sac silk than were the water-based sprays, delivering the active ingredients on most (>99%) of the eggs inside the sac. The ability of pesticides to penetrate spider egg sac silk and deliver lethal doses of active ingredients to the eggs is discussed in relation to the chemical nature of egg sac silk proteins. Our study suggests that pest management procedures primarily relying on perimeter application of water-based sprays might not provide satisfactory control of brown widow spider eggs. Determination of the most effective active ingredients and carrier characteristics warrant further research to provide more effective control options for spider egg sacs. © The Authors 2015.

Recent studies of the veterinary profession have established a need for training in various areas beyond those directed toward building competence and proficiency as a clinician. To address this need, a workshop was designed whose objective was to develop a detailed outline of a model curriculum that would encompass the skills, knowledge, aptitudes, and attitudes deemed essential for economic success in the veterinary profession. The model curriculum was created from comprehensive input provided by consultants and educators. Constraints for implementation of this curriculum are identified, and future directions are discussed.

Preventive-medicine consultations account for a large proportion of the veterinary caseload and previous research has suggested these consultations are fundamentally different from those in which the animal is presented for a specific health problem. There has been recent controversy around some aspects of preventive medicine for cats and dogs, and the full health benefits of the preventive-medicine consultation remain unclear. The aim of this study was to compare characteristics of the consultation and the problems discussed during the consultation between preventive-medicine consultations and other types of consultations. Data were gathered during direct observation of small-animal consultations in seven first-opinion practices in the United Kingdom. Data collected included type of clinical examination performed, patient signalment, and details of all problems discussed (including whether the problem was presenting or non-presenting, new or pre-existing, who had raised the problem, body system affected and whether an action was taken). A two-level multivariable logistic-regression model was developed, with canine and feline patients at Level 1 nested within consulting veterinary surgeons at Level 2, and a binary outcome variable of preventive-medicine consultation versus specific health-problem consultation. A total of 1807 patients were presented, of which 690 (38.2%) presented for a preventive-medicine consultation. Dogs were the most frequently presented species (n=1168; 64.6%) followed by cats (n=510; 28.2%), rabbits (n=86; 4.8%) and patients of other species (n=43; 2.4%). The five variables remaining in the multi-level model were whether multiple patients were presented, patient age, clinical examination type, weighing and number of problems discussed. Species, breed, sex, neutering status and practice did not remain in the final model. Many non-presenting problems, including both preventive-medicine problems and specific-health problems, were discussed and

Guide dogs and their owners will visit a veterinary practice at least twice a year. The aim of this study was to evaluate what guide dog owners thought about these visits, in order to identify areas of good practice which could be incorporated into the undergraduate curriculum. Nine guide dog owners volunteered to take part in the study and were interviewed by the primary researcher. Thematic analysis was carried out and several themes were identified: good experiences were highlighted where staff had an understanding of visual impairment and the work of a guide dog; the importance of good communication skills involving the owner in the consultation; the need for veterinary professionals to understand the bond between an owner and guide dog; how medication and information could be provided in a user-friendly format for someone affected by a visual impairment and concerns about costs and decision making for veterinary treatment. This work highlights the importance for veterinary staff to talk to, empathise with and understand the individual circumstances of their clients and identifies areas that should be included in veterinary education to better prepare students for the workplace.

S88-E-5161 (12-14-98) --- Before beginning their pre-sleep period on their next to last day in space, the STS-88 astronauts deployed a small 590-pound satellite called SAC-A for the Argentinean National Committee of Space Activities. Equipped with five technology experiments, including one to track the movement of whales off the coast of Argentina, SAC-A was ejected from a canister in Endeavour's cargo bay at 10:31 p.m. Central time as the shuttle few over the northern Indian Ocean. The satellite is expected to remain in orbit from five to nine months sending back data to Argentine researchers back on Earth. The photo was taken with an electronic still camera (ESC) at 04:35:48 GMT, Dec. 14.

Intranasal anatomy of the nasolacrimal sac in endoscopic dacryocystorhinostomy.

PubMed

Wormald, P J; Kew, J; Van Hasselt, A

2000-09-01

Intranasal surface anatomy is fundamental to the technique of endoscopic dacryocystorhinostomy. In the current literature the lacrimal sac is described as being situated anterior to the anterior end of the middle turbinate with between 0% and 20% of the sac above the insertion of the middle turbinate on the lateral nasal wall (the axilla of the middle turbinate). The aim of this study was to use CT dacryocystograms (DCGs) and CT scans to establish the relationship of the lacrimal sac to the lateral nasal wall. Forty-seven individual lacrimal sacs were measured in relation to the common canaliculus, and 76 were measured in relation to the insertion of the middle turbinate. Measurements taken from the long axis of the sac showed the mean height of the sac above the middle turbinate insertion was 8.8 mm (SD = 0.2, 95% CI = 1.3) and below it was 4.1 mm (SD = 2.3, 95% CI = 1.1). The average measurement of the sac above the com-mon canaliculus on CT DCGs was 5.3 mm (SD = 1.7, 95% CI = 0.56), whereas the average measurement below the common canaliculus was 7.7 mm (SD = 2, 95% CI = 1.3) (n = 47 CT DCGs). The findings in this study show that a major portion of the sac is locat-ed above the insertion of the anterior end of the middle turbinate and, in addition, that a significant part of the sac lies above the entry point of the common canaliculus. Knowledge of these findings can ensure that the sac is adequately exposed during dacryocystorhinostomy by removal of sufficient bone and mucosa above the anterior insertion of the middle turbinate.

To determine whether transvaginal ultrasound criteria alone can distinguish viable from non-viable gestational sacs at a single examination. A prospective descriptive study was undertaken and analysis performed on 211 pregnancies complicated by threatened abortion and empty gestation sacs diagnosed by transvaginal ultrasound. The main outcome measure was the final diagnosis of viable or non-viable gestation on subsequent transvaginal sonography. The study shows that a single transvaginal ultrasound examination is useful in differentiating viable from non-viable gestation sacs. The mean sac diameter (MSD) was found to be the most useful criterion for determining non-viability. An MSD of > or = 17 mm that lacked an embryo and an MSD of > or = 13 mm without visible yolk sac were reliable predictors of non-viable gestation sacs at a single examination with 100% specificity and 100% positive predictive value. An MSD > or = 13 mm without visible yolk sac was the most sensitive criterion. Using MSD criteria, 73% of non-viable gestations could be reliably identified without any false-positive diagnoses. Deformed shape, low position and thin decidual reaction are strong indicators of non-viable gestations but are not 100% accurate. There is still a significant proportion of empty sacs, where no accurate distinction between viable and non-viable can be made according to one criterion at a single examination and in these cases serial examinations should be carried out before any active management is advocated. In most cases, transvaginal sonographic criteria alone can distinguish viable from non-viable empty gestational sacs at a single examination.

To compared the ultrasound findings of the lacrimal sac between subjects with normal lacrimal systems those with chronic dacryocystitis. A retrospective study of 10 subjects with a normal lacrimal system (Group 1) and 10 with chronic dacryocystitis (Group 2) diagnosed according to B-mode ultrasound with a 10-MHz transducer and the direct-contact technique (AVISO, Quantel Medical) for lacrimal sac assessment. We analyzed the dimensions, features, and content of the sacs. Characteristics of the population: female: 6, Group 1; 8, Group 2; mean age 48.4 years (SD=19.9; range, 22-80 years), Group 1; 50.5 years (SD=15.5; range, 25-75 years), Group 2. The dimensions of the lacrimal sac were as follows: anteroposterior 1.86 and 10.99 mm in Groups 1 and 2, respectively, p<0.0001; vertical 9.79 and 14.13 mm in Groups 1 and 2, respectively, p=0.049. Qualitative evaluation of the lacrimal sac contents showed hypoechogenic content in Group 1 (10, 100%) and hyperechogenic punctiform content in Group 2 (10, 100%) with partial filling in seven cases (70%). Ultrasonography can differentiate normal lacrimal sacs from sacs compromised by chronic dacryocystitis, thus being useful as an adjunct to clinical examination and surgical planning.

On the robustness of SAC silencing in closed mitosis

NASA Astrophysics Data System (ADS)

Ruth, Donovan; Liu, Jian

Mitosis equally partitions sister chromatids to two daughter cells. This is achieved by properly attaching these chromatids via their kinetochores to microtubules that emanate from the spindle poles. Once the last kinetochore is properly attached, the spindle microtubules pull the sister chromatids apart. Due to the dynamic nature of microtubules, however, kinetochore-microtubule attachment often goes wrong. When this erroneous attachment occurs, it locally activates an ensemble of proteins, called the spindle assembly checkpoint proteins (SAC), which halts the mitotic progression until all the kinetochores are properly attached by spindle microtubules. The timing of SAC silencing thus determines the fidelity of chromosome segregation. We previously established a spatiotemporal model that addresses the robustness of SAC silencing in open mitosis for the first time. Here, we focus on closed mitosis by examining yeast mitosis as a model system. Though much experimental work has been done to study the SAC in cells undergoing closed mitosis, the processes responsible are not well understood. We leverage and extend our previous model to study SAC silencing mechanism in closed mitosis. We show that a robust signal of the SAC protein accumulation at the spindle pole body can be achieved. This signal is a nonlinear increasing function of number of kinetochore-microtubule attachments, and can thus serve as a robust trigger to time the SAC silencing. Together, our mechanism provides a unified framework across species that ensures robust SAC silencing and fidelity of chromosome segregation in mitosis. Intramural research program in NHLBI at NIH.

Veterinary vaccinology.

Veterinary vaccinology is a very interesting and rapidly developing field. In fact veterinary vaccines are not only used for the prevention of infectious diseases in the animal health sector, but also help to solve problems of public health, to reduce detrimental environmental impact of the use of some veterinary drugs and prevent the emergence of resistance of micro-organisms or parasites. After a short introduction, this paper will deal with the use of vaccines for animal health and welfare, including new developments in the veterinary field such as marker vaccines and vectored vaccines, the special case of equine influenza-inactivated vaccines and the use of veterinary vaccines in public health. The conclusions will analyse the reasons as to why develop veterinary vaccines and the obstacles to their development.

This study was conducted to provide normal reference features for canine and feline anal sacs using ultrasound, low-field magnetic resonance imaging (MRI) and radiograph contrast as diagnostic imaging tools. A total of ten clinically normal beagle dogs and eight clinically normally cats were included. General radiography with contrast, ultrasonography and low-field MRI scans were performed. The visualization of anal sacs, which are located at distinct sites in dogs and cats, is possible with a contrast study on radiography. Most surfaces of the anal sacs tissue, occasionally appearing as a hyperechoic thin line, were surrounded by the hypoechoic external sphincter muscle on ultrasonography. The normal anal sac contents of dogs and cats had variable echogenicity. Signals of anal sac contents on low-field MRI varied in cats and dogs, and contrast medium using T1-weighted images enhanced the anal sac walls more obviously than that on ultrasonography. In conclusion, this study provides the normal features of anal sacs from dogs and cats on diagnostic imaging. Further studies including anal sac evaluation are expected to investigate disease conditions.

SAC: Sheffield Advanced Code

Griffiths, Mike; Fedun, Viktor; Mumford, Stuart; Gent, Frederick

2013-06-01

The Sheffield Advanced Code (SAC) is a fully non-linear MHD code designed for simulations of linear and non-linear wave propagation in gravitationally strongly stratified magnetized plasma. It was developed primarily for the forward modelling of helioseismological processes and for the coupling processes in the solar interior, photosphere, and corona; it is built on the well-known VAC platform that allows robust simulation of the macroscopic processes in gravitationally stratified (non-)magnetized plasmas. The code has no limitations of simulation length in time imposed by complications originating from the upper boundary, nor does it require implementation of special procedures to treat the upper boundaries. SAC inherited its modular structure from VAC, thereby allowing modification to easily add new physics.

Common decisions made and actions taken during small-animal consultations at eight first-opinion practices in the United Kingdom.

2017-04-01

In order for veterinary surgeons to undertake an evidence-based approach to making decisions about their patients, it is important that new evidence is generated to support the clinical decision-making process. Many of the decisions are likely to be around the actions taken to treat or manage health problems discussed during the consultation, and little is currently known about the factors which affect the type of action taken. The aim of this study was to determine the decisions made and actions taken for health problems discussed during first-opinion small-animal consultations, as well as identifying factors which may affect the decision-making process. Data were gathered during direct observation of small-animal consultations conducted by 62 veterinary surgeons in eight first-opinion practices in the United Kingdom. For each patient presented, data were gathered on all health problems discussed during the consultation. The decision made (whether an action was taken or not) and the action taken where applicable (e.g. therapeutic treatment with antibiotics) was also recorded. A three-level multivariable logistic-regression model was developed, with problem (Level 1) nested within patient (Level 2) nested within consulting veterinary surgeon (Level 3), and a binary outcome variable of action versus no action. At least one action was taken for 69% (n=2203/3192) of all problems discussed. Therapeutic treatment was the most common action taken (n=1286/3192 problems; 40.3%), followed by management advice (n=1040/3192; 32.6%) and diagnostic work-up (n=323/3192; 10.1%). The most common therapeutic treatment was antibiotics (n=386/1286; 30%), while the most common management advice given was dietary advice (n=509/1040; 48.9%). The three explanatory variables remaining in the final model were whether the problem was a presenting or non-presenting problem, the type of diagnosis made, and the body system affected.

To evaluate the clinical usefulness of measuring the lacrimal sac fossa length using orbital computed tomography in normal Koreans. The authors retrospectively evaluated 140 patients (70 males and 70 females) who underwent orbital computed tomography at Guro Hospital and who had no history of orbital disease or orbital trauma. Computed tomography scans of the right orbit, including the proportion of the lacrimal bone and maxillary bone that comprise the lacrimal sac fossa, were evaluated at 3 different axial planes (lower, middle, and upper levels). Additionally, the mid-point thickness and maximum thickness of the maxillary bone were measured. Finally, the authors also evaluated the relationship between nasal bone height and maxillary bone thickness in the lacrimal sac fossa. Maxillary bone thickness in the lacrimal sac fossa was thicker in males than in females at mid-point thickness and maximum thickness (P < 0.05). However, there was no significant difference in the size of the lacrimal sac fossa and the proportion of the maxillary bone between males and females.In comparisons between maxillary cross-sections, bone thickness was greater toward the upper level of the lacrimal sac fossa (P = 0.008), and the proportion of the maxillary bone was also greater (P = 0.006).Aging had a significant positive correlation with maxillary bone thickness at all 3 axial planes (P < 0.05), but there was no relationship between age and maxillary bone proportion. Nasal bone height and maxillary bone thickness were also not significantly related. In comprising the lacrimal sac fossa, the maxillary bone accounted for a bigger proportion than the lacrimal bone. Male maxillary bone thickness was greater than female thickness. The authors also observed that maxillary bone thickness increased toward the upper areas of the lacrimal sac fossa and with increasing subject age. Understanding the form and variation of a normal lacrimal sac fossa is helpful for preparing for a

Specific lignin accumulation in granulated juice sacs of Citrus maxima.

Juice sac granulation occurring in pummelo fruits [Citrus maxima (Burm.) Merr.] is an undesirable trait, and the underlying mechanism remains unresolved. Previous studies have shown that lignin metabolism is closely associated with the process of juice sac granulation. Here, a method suitable for lignin isolation from pummelo tissues is established. Acetylated lignins from different pummelo tissues and cultivars were analyzed by HSQC NMR. The results showed that lignins in granulated juice sacs were characterized by an extremely high abundance of guaiacyl units (91.13-96.82%), in contrast to lignins from other tissues, including leaves, stems, and segment membranes. The abnormally accumulated lignins in granulated juice sacs were specific and mainly polymerized from coniferyl alcohol. No significant difference was found in lignin types among various cultivars. These findings indicated that the mechanism of juice sac granulation might be similar among various cultivars, although very different degrees of juice sac granulation can be observed.

XPS of oxygen atoms on Ag(111) and Ag(110) surfaces: accurate study with SAC/SAC-CI combined with dipped adcluster model.

Ishikawa, Atsushi; Nakatsuji, Hiroshi

2013-08-05

O1s core-electron binding energies (CEBE) of the atomic oxygens on different Ag surfaces were investigated by the symmetry adapted cluster-configuration interaction (SAC-CI) method combined with the dipped adcluster model, in which the electron exchange between bulk metal and adsorbate is taken into account properly. Electrophilic and nucleophilic oxygens (O(elec) and O(nuc)) that might be important for olefin epoxidation in a low-oxygen coverage condition were focused here. We consider the O1s CEBE as a key property to distinguish the surface oxygen states, and series of calculation was carried out by the Hartree-Fock, Density functional theory, and SAC/SAC-CI methods. The experimental information and our SAC/SAC-CI results indicate that O(elec) is the atomic oxygen adsorbed on the fcc site of Ag(111) and that O(nuc) is the one on the reconstructed added-row site of Ag(110) and that one- and two-electron transfers occur, respectively, to the O(elec) and O(nuc) adclusters from the silver surface.

Stained cytological specimens from 7 canine anal sac gland adenomas and 11 canine anal sac gland carcinomas were analyzed by computer-assisted nuclear morphometry. In each case, the nuclei of at least 100 neoplastic cells were measured, and the mean nuclear area (MNA), mean nuclear perimeter (MNP), mean nuclear diameter (MND) and nuclear roundness (NR) were calculated. The study aimed to evaluate (1) the possibility of using nuclear cytomorphometry as an auxiliary diagnostic method to differentiate between canine anal sac gland adenomas and adenocarcinomas, and (2) the prognostic value of nuclear morphometry in canine anal sac gland adenocarcinomas. The results indicated that (1) MNA, MNP, MND and NR could be used as effective auxiliary tools for differential diagnosis between canine anal sac gland adenomas and adenocarcinomas, and (2) MNA, MNP and MND are reliable prognostic indicators for canine anal sac gland adenocarcinomas.

Applicability of the Calgary-Cambridge Guide to Dog and Cat Owners for Teaching Veterinary Clinical Communications.

Effective communication in health care benefits patients. Medical and veterinary schools not only have a responsibility to teach communication skills, the American Veterinary Medical Association (AVMA) Council on Education (COE) requires that communication be taught in all accredited colleges of veterinary medicine. However, the best strategy for designing a communications curriculum is unclear. The Calgary-Cambridge Guide (CCG) is one of many models developed in human medicine as an evidence-based approach to structuring the clinical consultation through 71 communication skills. The model has been revised by Radford et al. (2006) for use in veterinary curricula; however, the best approach for veterinary educators to teach communication remains to be determined. This qualitative study investigated if one adaptation of the CCG currently taught at Midwestern University College of Veterinary Medicine (MWU CVM) fulfills client expectations of what constitutes clinically effective communication. Two focus groups (cat owners and dog owners) were conducted with a total of 13 participants to identify common themes in veterinary communication. Participants compared communication skills they valued to those taught by MWU CVM. The results indicated that while the CCG skills that MWU CVM adopted are applicable to cat and dog owners, they are not comprehensive. Participants expressed the need to expand the skillset to include compassionate transparency and unconditional positive regard. Participants also expressed different communication needs that were attributed to the species of companion animal owned.

Frequent and unregulated use of antimicrobials (AM) in livestock requires public health attention as a likely selection pressure for resistant bacteria. Studies among small-holders, who own a large percentage of the world’s livestock, are vital for understanding how practices involving AM use might influence resistance. We present a cultural-ecological mixed-methods analysis to explore sectors of veterinary care, loosely regulated AM use, and human exposure to AMs through meat and milk consumption across three rural to peri-urban Tanzanian ethnic groups (N = 415 households). Reported use of self-administered AMs varied by ethnic group (Maasai: 74%, Arusha: 21%, Chagga: 1%) as did consultation with professional veterinarians (Maasai: 36%, Arusha: 45%, Chagga: 96%) and observation of withdrawal of meat and milk from consumption during and following AM treatment (Maasai: 7%, Arusha: 72%, Chagga: 96%). The antibiotic oxytetracycline was by far the most common AM in this sample. Within ethnic groups, herd composition differences, particularly size of small-stock and cattle herds, were most strongly associated with differences in lay AM use. Among the Arusha, proxies for urbanization, including owning transportation and reliance on “zero-grazing” herds had the strongest positive associations with veterinarian consultation, while distance to urban centers was negatively associated. For Maasai, consultation was negatively associated with use of traditional healers or veterinary drug-shops. Observation of withdrawal was most strongly associated with owning technology among Maasai while Arusha observance displayed seasonal differences. This “One-Health” analysis suggests that livelihood and cultural niche factors, through their association with practices in smallholder populations, provide insight into the selection pressures that may contribute to the evolution and dissemination of antimicrobial resistance.

[Links between non-professional agents and the official Veterinary Services in sub-Saharan Africa].

Para-professional agents known as auxiliaries, or community animal health workers, provide low-cost basic veterinary services to communities of livestock producers. A 2003 survey of 16 Sub-Saharan African countries, carried out as part of the Pan-African Programme for the Control of Epizootics, showed that in the majority of cases, the official Veterinary Services have no (or very few) links with the auxiliaries, although they are well aware of their existence and in some cases the auxiliaries have been trained by officials of the Veterinary Services. However, there are isolated cases of countries establishing more formal links, for example, recognising the status of an auxiliary, recognising auxiliaries with no definition of a status, attaching auxiliaries to Veterinary Service staff, establishing agreements for the provision of auxiliary services through livestock producer associations, harmonising auxiliary training programmes, issuing professional auxiliary cards, and setting up a consultation framework on the issue of auxiliaries. Unlike private veterinarians, agents of the official services do not generally perceive auxiliaries as competitors, and sometimes collaboration develops at this level. The authors propose several measures to improve links between the official Veterinary Services and auxiliaries, as follows: the fields of competence of auxiliaries should be defined and their curriculum harmonised, the status of auxiliaries should be recognised, a monitoring and assessment mechanism should be established at senior level in the Veterinary Services, training for livestock producers should be improved.

Various different methods are currently being used to capture data from small animal consultations. The aim of this study was to develop a tool to record detailed data from consultations by direct observation. A second aim was to investigate the complexity of the consultation by examining the number of problems discussed per patient. A data collection tool was developed and used during direct observation of small animal consultations in eight practices. Data were recorded on consultation type, patient signalment and number of problems discussed. During 16 weeks of data collection, 1901 patients were presented. Up to eight problems were discussed for some patients; more problems were discussed during preventive medicine consultations than during first consultations (P<0.001) or revisits (P<0.001). Fewer problems were discussed for rabbits than cats (P<0.001) or dogs (P<0.001). Age was positively correlated with discussion of specific health problems and negatively correlated with discussion of preventive medicine. Consultations are complex with multiple problems frequently discussed, suggesting comorbidity may be common. Future research utilising practice data should consider how much of this complexity needs to be captured, and use appropriate methods accordingly. The findings here have implications for directing research and education as well as application in veterinary practice. PMID:25262057

Highlights: •We assess PAS complex proteins and phosphoinositide levels in breast cancer cells. •Sac3 and ArPIKfyve are markedly elevated in triple-negative breast cancer cells. •Sac3 silencing inhibits proliferation in triple-negative breast cancer cell lines. •Phosphoinositide profiles are altered in breast cancer cells. •This is the first evidence linking high Sac3 with breast cancer cell proliferation. -- Abstract: The phosphoinositide 5-kinase PIKfyve and 5-phosphatase Sac3 are scaffolded by ArPIKfyve in the PIKfyve–ArPIKfyve–Sac3 (PAS) regulatory complex to trigger a unique loop of PtdIns3P–PtdIns(3,5)P{sub 2} synthesis and turnover. Whereas the metabolizing enzymes of the other 3-phosphoinositides have already been implicated in breast cancer,more » the role of the PAS proteins and the PtdIns3P–PtdIns(3,5)P{sub 2} conversion is unknown. To begin elucidating their roles, in this study we monitored the endogenous levels of the PAS complex proteins in cell lines derived from hormone-receptor positive (MCF7 and T47D) or triple-negative breast cancers (TNBC) (BT20, BT549 and MDA-MB-231) as well as in MCF10A cells derived from non-tumorigenic mastectomy. We report profound upregulation of Sac3 and ArPIKfyve in the triple negative vs. hormone-sensitive breast cancer or non-tumorigenic cells, with BT cell lines showing the highest levels. siRNA-mediated knockdown of Sac3, but not that of PIKfyve, significantly inhibited proliferation of BT20 and BT549 cells. In these cells, knockdown of ArPIKfyve had only a minor effect, consistent with a primary role for Sac3 in TNBC cell proliferation. Intriguingly, steady-state levels of PtdIns(3,5)P{sub 2} in BT20 and T47D cells were similar despite the 6-fold difference in Sac3 levels between these cell lines. However, steady-state levels of PtdIns3P and PtdIns5P, both regulated by the PAS complex, were significantly reduced in BT20 vs. T47D or MCF10A cell lines, consistent with elevated Sac3 affecting

The provision of veterinary clinical services is known to elicit a range of challenges which require an ethical appraisal. In a recent Policy Delphi study, referrals/second opinions and 24 h emergency care were identified as matters of key concern by veterinary professionals in Ireland. In this case study (the first in a series of three resulting from a research workshop exploring challenges facing the veterinary profession in Ireland; the other two case studies investigate the on-farm use of veterinary antimicrobials and emergency/casualty slaughter certification) we aim to provide a value-based reflection on the constraints and possible opportunities for two prominent veterinary clinical services in Ireland: referrals/second opinions and 24 h emergency care. Using a qualitative focus group approach, this study gathered evidence from relevant stakeholders, namely referral and referring veterinarians, clients, animal charities, and the regulatory body. Six overarching, interrelated constraints emerged from the thematic analysis: the need to improve current guidance, managing clients' expectations, concerns with veterinarian well-being, financial issues, timeliness of referral, and conflicts between veterinary practices. Possible solutions to improve veterinary referral and out-of-hours clinical services included clarifying the terms used in current norms and regulations (namely 'referral', 'second opinion', '24 h emergency care' and '24 h cover'), improved communication (making the client aware of the different levels of veterinary care that are being offered, and transparent and full disclosure of clinical records), and the promotion of Continuing Veterinary Education in communication, business management and ethical decision-making. These findings may help inform the Veterinary Council of Ireland about future recommendations and regulatory measures.

The vocal sac of Hylodidae (Amphibia, Anura): Phylogenetic and functional implications of a unique morphology.

PubMed

Elias-Costa, Agustin J; Montesinos, Rachel; Grant, Taran; Faivovich, Julián

2017-11-01

Anuran vocal sacs are elastic chambers that recycle exhaled air during vocalizations and are present in males of most species of frogs. Most knowledge of the diversity of vocal sacs relates to external morphology; detailed information on internal anatomy is available for few groups of frogs. Frogs of the family Hylodidae, which is endemic to the Atlantic Forest of Brazil and adjacent Argentina and Paraguay, have three patterns of vocal sac morphology-that is, single, subgular; paired, lateral; and absent. The submandibular musculature and structure of the vocal sac mucosa (the internal wall of the vocal sac) of exemplar species of this family and relatives were studied. In contrast to previous accounts, we found that all species of Crossodactylus and Hylodes possess paired, lateral vocal sacs, with the internal mucosa of each sac being separate from the contralateral one. Unlike all other frogs for which data are available, the mucosa of the vocal sacs in these genera is not supported externally by the mm. intermandibularis and interhyoideus. Rather, the vocal sac mucosa projects through the musculature and is free in the submandibular lymphatic sac. The presence of paired, lateral vocal sacs, the internal separation of the sac mucosae, and their projection through the m. interhyoideus are synapomorphies of the family. Furthermore, the specific configuration of the m. interhyoideus allows asymmetric inflation of paired vocal sacs, a feature only reported in species of these diurnal, stream-dwelling frogs. © 2017 Wiley Periodicals, Inc.

Intraoperative Sac Pressure Measurement During Endovascular Abdominal Aortic Aneurysm Repair

PurposeIntraoperative sac pressure was measured during endovascular abdominal aortic aneurysm repair (EVAR) to evaluate the clinical significance of sac pressure measurement.MethodsA microcatheter was placed in an aneurysm sac from the contralateral femoral artery, and sac pressure was measured during EVAR procedures in 47 patients. Aortic blood pressure was measured as a control by a catheter from the left brachial artery.ResultsThe systolic sac pressure index (SPI) was 0.87 {+-} 0.10 after main-body deployment, 0.63 {+-} 0.12 after leg deployment (P < 0.01), and 0.56 {+-} 0.12 after completion of the procedure (P < 0.01). Pulse pressure was 55 {+-} 21 mmHg,more » 23 {+-} 15 mmHg (P < 0.01), and 16 {+-} 12 mmHg (P < 0.01), respectively. SPI showed no significant differences between the Zenith and Excluder stent grafts (0.56 {+-} 0.13 vs. 0.54 {+-} 0.10, NS). Type I endoleak was found in seven patients (15%), and the SPI decreased from 0.62 {+-} 0.10 to 0.55 {+-} 0.10 (P = 0.10) after fixing procedures. Type II endoleak was found in 12 patients (26%) by completion angiography. The SPI showed no difference between type II endoleak positive and negative (0.58 {+-} 0.12 vs. 0.55 {+-} 0.12, NS). There were no significant differences between the final SPI of abdominal aortic aneurysms in which the diameter decreased in the follow-up and that of abdominal aortic aneurysms in which the diameter did not change (0.53 {+-} 0.12 vs. 0.57 {+-} 0.12, NS).ConclusionsSac pressure measurement was useful for instant hemodynamic evaluation of the EVAR procedure, especially in type I endoleaks. However, on the basis of this small study, the SPI cannot be used to reliably predict sac growth or regression.« less

pH sensing via bicarbonate-regulated “soluble” adenylyl cyclase (sAC)

PubMed Central

Rahman, Nawreen; Buck, Jochen; Levin, Lonny R.

2013-01-01

Soluble adenylyl cyclase (sAC) is a source of the second messenger cyclic adenosine 3′, 5′ monophosphate (cAMP). sAC is directly regulated by bicarbonate (HCO−3) ions. In living cells, HCO−3 ions are in nearly instantaneous equilibrium with carbon dioxide (CO2) and pH due to the ubiquitous presence of carbonic anhydrases. Numerous biological processes are regulated by CO2, HCO−3, and/or pH, and in a number of these, sAC has been shown to function as a physiological CO2/HCO3/pH sensor. In this review, we detail the known pH sensing functions of sAC, and we discuss two highly-studied, pH-dependent pathways in which sAC might play a role. PMID:24324443

Hernia sac of indirect inguinal hernia: invagination, excision, or ligation?

PubMed

Othman, I; Hady, H A

2014-04-01

This study compares the effect of invaginating excision of hernia sac without ligation with the traditional method of high ligation of the hernia sac on postoperative pain and recurrence. This multicenter prospective randomized study included 152 patients with 167 primary indirect inguinal hernias. In group I (54 hernias), the sac was not opened and was inverted with the finger into the peritoneal cavity. In group E (56 hernias), the sac was excised at the neck without ligation. In group L (57 hernias), the sac was transfixed at the neck and excised in the traditional manner. The repair of the posterior wall of the inguinal canal was done according to Lichtenstein tension-free technique. Mean length of follow-up was 81.50 ± 22.34, 79.35 ± 26.76, and 77.83 ± 21.26 months, respectively. Postoperative seroma occurred in 1 patient (0.60%) in group E and 1 patient (0.60%) in group L. Surgical site infection occurred in 2 patients (1.20%) in group I, 1 patient (0.60%) in group E, and 2 patients (1.20%) in group L. Mean postoperative pain score was 3.04 ± 2.11, 3.98 ± 2.33 and 4.06 ± 2.43, respectively (p: 0.049). Chronic pain occurred in 3 patients in group I (1.80%), 3 patients in group E (1.80%), and 5 patients in group L (3.00%) (p: 0.749). The difference between the complications in three groups was statistically insignificant (p: 0.887). Hernia recurrence occurred in 3 patients (1.80%) in group I, 1 patient (0.60%) in group E, and 1 patient (0.60%) in group L (p: 0.429). Invagination and excision of the hernia sac do not have adverse effects on repair integrity. They limit the dissection and reduce the morbidity and risk of injury to the spermatic cord and surrounded structures. They are safer and more appropriate for repair of sliding hernia. Ligation of the hernia sac in inguinal hernia surgery is not only unnecessary and time consuming but also leads to increased postoperative pain. Recurrence rates are statistically unaffected by not ligating the sac.

New directions for veterinary technology.

PubMed

Chadderdon, Linda M; Lloyd, James W; Pazak, Helene E

2014-01-01

Veterinary technology has generally established itself well in companion-animal and mixed-animal veterinary medical practice, but the career's growth trajectory is uncertain. Michigan State University (MSU) convened a national conference, "Creating the Future of Veterinary Technology-A National Dialogue," in November 2011 to explore ways to elevate the veterinary technician/technologist's role in the veterinary medical profession and to identify new directions in which the career could expand. Veterinary technicians/technologists might advance their place in private practice by not only improving their clinical skills, but by also focusing on areas such as practice management, leadership training, business training, conflict resolution, information technology, and marketing/communications. Some new employment settings for veterinary technicians/technologists include more participation within laboratory animal medicine and research, the rural farm industry, regulatory medicine, and shelter medicine. Achieving these ends would call for new training options beyond the current 2-year and 4-year degree programs. Participants suggested specialty training programs, hybrid programs of various types, online programs, veterinary technician residency programs of 12-18 months, and more integration of veterinary technician/technology students and veterinary medicine students at colleges of veterinary medicine.

The Evolutionary Economics of Embryonic-Sac Fluids in Squamate Reptiles.

PubMed

Bonnet, Xavier; Naulleau, Guy; Shine, Richard

2017-03-01

The parchment-shelled eggs of squamate reptiles take up substantial water from the nest environment, enabling the conversion of yolk into neonatal tissue and buffering the embryo against the possibility of subsequent dry weather. During development, increasing amounts of water are stored in the embryonic sacs (i.e., membranes around the embryo: amnion, allantois, and chorion). The evolution of viviparity (prolonged uterine retention of developing embryos) means that embryonic-sac fluid storage now imposes a cost (increased maternal burdening), confers less benefit (because the mother buffers fetal water balance), and introduces a potential conflict among uterine siblings (for access to finite water supplies). Our data on nine species of squamate reptiles and published information on three species show that the embryonic-sac fluids comprise around 33% of neonatal mass in viviparous species versus 94% in full-term eggs of oviparous squamates. Data on parturition in 149 vipers (Vipera aspis, a viviparous species) show that larger offspring store more fluids in their fetal sacs and that an increase in litter size is associated with a decrease in fluid-sac mass per offspring. Overall, the evolutionary transition from oviparity to viviparity may have substantially altered selective forces on offspring packaging and created competition among offspring for access to water reserves during embryonic development.

Age and egg-sac loss determine maternal behaviour and locomotor activity of wolf spiders (Araneae, Lycosidae).

PubMed

Ruhland, Fanny; Chiara, Violette; Trabalon, Marie

2016-11-01

Wolf spiders' (Lycosidae) maternal behaviour includes a specific phase called "egg brooding" which consists of guarding and carrying an egg-sac throughout the incubation period. The transport of an egg-sac can restrict mothers' exploratory and locomotor activity, in particular when foraging. The present study details the ontogeny of maternal behaviour and assesses the influence of age of egg-sac (or embryos' developmental stage) on vagrant wolf spider Pardosa saltans females' exploration and locomotion. We observed these spiders' maternal behaviour in the laboratory and evaluated their locomotor activity using a digital activity recording device. Our subjects were virgin females (without egg-sac) and first time mothers (with her egg-sac) who were divided into three groups. The first group of mothers were tested on the day the egg-sac was built (day 0), and the females of the other two groups were tested 10 or 15days after they had built their egg-sac. We evaluated the effects of the presence and the loss of egg-sac on mothers' activity. Pardosa saltans females' behaviour depended on mothers' physiological state and/or age of egg-sac (developmental stage of embryos). Virgin females' behaviour was not modified by the presence of an egg-sac in their environment. Mothers' reactions to the presence, the loss and the recovery of their egg-sac varied during the maternal cycle. Maternal behaviour changed with age of egg-sac, but the levels of locomotor activity of mothers with egg-sacs was similar to those of virgin females. Loss of egg-sac modified the maternal behaviour and locomotor activity of all mothers; these modifications were greater on "day 15" when embryos had emerged from eggs. All mothers were able to retrieve their egg-sacs and to re-attach them to their spinnerets. Copyright © 2016 Elsevier B.V. All rights reserved.

Global veterinary leadership.

The public needs no reminder that deadly infectious diseases such as FMD could emerge in any country at any moment, or that national food security could be compromised by Salmonella or Listeria infections. Protections against these risks include the knowledge that appropriate and equivalent veterinary education will enable detection and characterization of emerging disease agents, as well as an appropriate response, wherever they occur. Global veterinary leadership is needed to reduce the global threat of infectious diseases of major food animal and public health importance. We believe that the co-curriculum is an excellent way to prepare and train veterinarians and future leaders who understand and can deal with global issues. The key to the success of the program is the veterinarian's understanding that there is a cultural basis to the practice of veterinary medicine in any country. The result will be a cadre of veterinarians, faculty, and other professionals who are better able (language and culture) to understand the effects of change brought about by free trade and the importance of interdisciplinary and institutional relationships to deal effectively with national and regional issues of food safety and security. New global veterinary leadership programs will build on interests, experience, ideas, and ambitions. A college that wishes to take advantage of this diversity must offer opportunities that interest veterinarians throughout their careers and that preferably connect academic study with intensive experiential training in another country. At its best, the global veterinary leadership program would include a partnership between veterinarians and several international learning centers, a responsiveness to the identified international outreach needs of the profession, and attention to critical thinking and reflection. The global veterinary leadership program we have described is intended to be a set of ideas meant to promote collaboration, coalitions, and

Integrative veterinary medicine (IVM) describes the combination of complementary and alternative therapies with conventional care and is guided by the best available evidence. Veterinarians frequently encounter questions about complementary and alternative veterinary medicine (CAVM) in practice, and the general public has demonstrated increased interest in these areas for both human and animal health. Consequently, veterinary students should receive adequate exposure to the principles, theories, and current knowledge supporting or refuting such techniques. A proposed curriculum guideline would broadly introduce students to the objective evaluation of new veterinary treatments while increasing their preparation for responding to questions about IVM in clinical practice. Such a course should be evidence-based, unbiased, and unaffiliated with any particular CAVM advocacy or training group. All IVM courses require routine updating as new information becomes available. Controversies regarding IVM and CAVM must be addressed within the course and throughout the entire curriculum. Instructional honesty regarding the uncertainties in this emerging field is critical. Increased training of future veterinary professionals in IVM may produce an openness to new ideas that characterizes the scientific method and a willingness to pursue and incorporate evidence-based medicine in clinical practice with all therapies, including those presently regarded as integrative, complementary, or alternative.

For many years after its invention around 1796, homeopathy was widely used in people and later in animals. Over the intervening period (1796-2016) pharmacology emerged as a science from Materia Medica (medicinal materials) to become the mainstay of veterinary therapeutics. There remains today a much smaller, but significant, use of homeopathy by veterinary surgeons. Homeopathic products are sometimes administered when conventional drug therapies have not succeeded, but are also used as alternatives to scientifically based therapies and licensed products. The principles underlying the veterinary use of drug-based and homeopathic products are polar opposites; this provides the basis for comparison between them. This two-part review compares and contrasts the two treatment forms in respect of history, constituents, methods of preparation, known or postulated mechanisms underlying responses, the legal basis for use and scientific credibility in the 21st century. Part 1 begins with a consideration of why therapeutic products actually work or appear to do so. British Veterinary Association.

Evidence for Avian Intrathoracic Air Sacs in a New Predatory Dinosaur from Argentina

PubMed Central

Sereno, Paul C.; Martinez, Ricardo N.; Wilson, Jeffrey A.; Varricchio, David J.; Alcober, Oscar A.; Larsson, Hans C. E.

2008-01-01

Background Living birds possess a unique heterogeneous pulmonary system composed of a rigid, dorsally-anchored lung and several compliant air sacs that operate as bellows, driving inspired air through the lung. Evidence from the fossil record for the origin and evolution of this system is extremely limited, because lungs do not fossilize and because the bellow-like air sacs in living birds only rarely penetrate (pneumatize) skeletal bone and thus leave a record of their presence. Methodology/Principal Findings We describe a new predatory dinosaur from Upper Cretaceous rocks in Argentina, Aerosteon riocoloradensis gen. et sp. nov., that exhibits extreme pneumatization of skeletal bone, including pneumatic hollowing of the furcula and ilium. In living birds, these two bones are pneumatized by diverticulae of air sacs (clavicular, abdominal) that are involved in pulmonary ventilation. We also describe several pneumatized gastralia (“stomach ribs”), which suggest that diverticulae of the air sac system were present in surface tissues of the thorax. Conclusions/Significance We present a four-phase model for the evolution of avian air sacs and costosternal-driven lung ventilation based on the known fossil record of theropod dinosaurs and osteological correlates in extant birds: (1) Phase I—Elaboration of paraxial cervical air sacs in basal theropods no later than the earliest Late Triassic. (2) Phase II—Differentiation of avian ventilatory air sacs, including both cranial (clavicular air sac) and caudal (abdominal air sac) divisions, in basal tetanurans during the Jurassic. A heterogeneous respiratory tract with compliant air sacs, in turn, suggests the presence of rigid, dorsally attached lungs with flow-through ventilation. (3) Phase III—Evolution of a primitive costosternal pump in maniraptoriform theropods before the close of the Jurassic. (4) Phase IV—Evolution of an advanced costosternal pump in maniraptoran theropods before the close of the

PurposeThe purpose of this study was to demonstrate a sac angiography technique and evaluate the feasibility of N-butyl cyanoacrylate (NBCA) embolization of the ruptured abdominal aortic aneurysm (AAA) sac in emergency endovascular aneurysm repair (EVAR) in hemodynamically unstable patients.MethodsA retrospective case series of three patients in whom sac angiography was performed during emergency EVAR for ruptured AAA was reviewed. After stent graft deployment, angiography within the sac of aneurysm (sac angiography) was performed by manually injecting 10 ml of contrast material through a catheter to identify the presence and site of active bleeding. In two patients, sac angiography revealed active extravasationmore » of the contrast material, and NBCA embolization with a coaxial catheter system was performed to achieve prompt sealing.ResultsSac angiography was successful in all three patients. In the two patients who underwent NBCA embolization for aneurysm sac bleeding, follow-up computed tomography (CT) images demonstrated the accumulation of NBCA consistent with the bleeding site in preprocedural CT images.ConclusionsEVAR is associated with a potential risk of ongoing bleeding from type II or IV endoleaks into the disrupted aneurysm sac in patients with severe coagulopathy. Therefore, sac angiography and NBCA embolization during emergency EVAR may represent a possible technical improvement in the treatment of ruptured AAA in hemodynamically unstable patients.« less

To assess the impact of endometriosis of the posterior cul-de-sac on quality of sleep, average daytime sleepiness and insomnia. This age-matched case-control study was conducted in a tertiary referral centre for the diagnosis and treatment of endometriosis between May 2012 and December 2013. It included 145 women with endometriosis of the posterior cul-de-sac (cases; group E) and 145 patients referred to our Institution because of routine gynaecologic consultations (controls; group C). This study investigated whether sleep is impaired in patients with endometriosis of the posterior cul-de-sac. Sleep quality, daytime sleepiness and insomnia were assessed using the following self-administered questionnaires: the Pittsburgh Sleep Quality Index, the Epworth sleepiness scale and the Insomnia Severity Index, respectively. The primary objective of the study was to evaluate sleep quality in the two study groups. Secondary outcomes of the study were to assess average daytime sleepiness and insomnia in the two study groups. The prevalence of poor sleep quality was significantly higher in group E (64.8%) than in group C (15.1%; p<0.001). The prevalence of excessive daytime sleepiness was significantly higher in group E (23.4%) than in group C (12.9%; p=0.033). Patients of group E experienced subthreshold insomnia (29.0%) and moderate clinical insomnia (16.6%) significantly more frequently than patients in group C (24.4% and 5.0%; p=0.002). A substantial proportion of women with endometriosis of the posterior cul-de-sac experiences poor sleep quality, excessive daytime sleepiness and insomnia. Copyright © 2015 Elsevier Ireland Ltd.

Established and potential physiological roles of bicarbonate-sensing soluble adenylyl cyclase (sAC) in aquatic animals

PubMed Central

Tresguerres, Martin; Barott, Katie L.; Barron, Megan E.; Roa, Jinae N.

2014-01-01

Soluble adenylyl cyclase (sAC) is a recently recognized source of the signaling molecule cyclic AMP (cAMP) that is genetically and biochemically distinct from the classic G-protein-regulated transmembrane adenylyl cyclases (tmACs). Mammalian sAC is distributed throughout the cytoplasm and it may be present in the nucleus and inside mitochondria. sAC activity is directly stimulated by HCO3−, and sAC has been confirmed to be a HCO3− sensor in a variety of mammalian cell types. In addition, sAC can functionally associate with carbonic anhydrases to act as a de facto sensor of pH and CO2. The two catalytic domains of sAC are related to HCO3−-regulated adenylyl cyclases from cyanobacteria, suggesting the cAMP pathway is an evolutionarily conserved mechanism for sensing CO2 levels and/or acid/base conditions. Reports of sAC in aquatic animals are still limited but are rapidly accumulating. In shark gills, sAC senses blood alkalosis and triggers compensatory H+ absorption. In the intestine of bony fishes, sAC modulates NaCl and water absorption. And in sea urchin sperm, sAC may participate in the initiation of flagellar movement and in the acrosome reaction. Bioinformatics and RT-PCR results reveal that sAC orthologs are present in most animal phyla. This review summarizes the current knowledge on the physiological roles of sAC in aquatic animals and suggests additional functions in which sAC may be involved. PMID:24574382

These guidelines for veterinary medical care and veterinary hospitals are written to conform with the requirements of the Animal Welfare Act, which states that programs of disease prevention and parasite control, euthanasia, and adequate veterinary care shall be established and maintained under the supervision of a veterinarian. Ideally the zoo and aquarium should be providing the best possible veterinary medical care for the animals in their collections. Many of these animals are rare and endangered and the institutions should endeavor both to provide for the long term health and well being of these animals and to advance the field of non-domestic animal medicine. It is hoped that this publication will aid in this process.

Errors in veterinary practice: preliminary lessons for building better veterinary teams.

2015-11-14

Case studies in two typical UK veterinary practices were undertaken to explore teamwork, including interprofessional working. Each study involved one week of whole team observation based on practice locations (reception, operating theatre), one week of shadowing six focus individuals (veterinary surgeons, veterinary nurses and administrators) and a final week consisting of semistructured interviews regarding teamwork. Errors emerged as a finding of the study. The definition of errors was inclusive, pertaining to inputs or omitted actions with potential adverse outcomes for patients, clients or the practice. The 40 identified instances could be grouped into clinical errors (dosing/drugs, surgical preparation, lack of follow-up), lost item errors, and most frequently, communication errors (records, procedures, missing face-to-face communication, mistakes within face-to-face communication). The qualitative nature of the study allowed the underlying cause of the errors to be explored. In addition to some individual mistakes, system faults were identified as a major cause of errors. Observed examples and interviews demonstrated several challenges to interprofessional teamworking which may cause errors, including: lack of time, part-time staff leading to frequent handovers, branch differences and individual veterinary surgeon work preferences. Lessons are drawn for building better veterinary teams and implications for Disciplinary Proceedings considered. British Veterinary Association.

SAC-C is an international Earth observing satellite mission conceived as a partnership between CONAE and NASA, but with additional support in instrumentation and satellite development from the Danish DSRI, the Italian ASI, the French CNES and the Brazilian INPE. A Delta II rocket successfully launched it on November 21st, 2000, from Vandenberg AFB, California, USA. SAC-C has been designed primarily to fulfill the requirements of countries with large extension of territory or scarcely populated like Argentina. Its design is a good compromise between resolution and swath width that makes SAC-C an appropriate tool for global and high dynamic phenomena studies. There are ten instruments on board of SAC-C that will perform different studies, the Multispectral Medium Resolution Scanner (MMRS), provided by CONAE, Argentina, will help in the studies about desertification processes evaluation and their evolution in time (i.e., Patagonia, Argentina), to identify and predict agriculture production, to monitor flood areas and to make studies in coastal and fluvial areas. The MMRS will be associated with a High Resolution Technological Camera (HRTC), also provided by CONAE that will permit improvement in the MMRS resolution in the areas where it will be required. A High Sensitivity Technological Camera (HSTC) is also included in the mission. SAC-C also carries instruments to monitor the condition and dynamics of the terrestrial and marine biosphere and environment (GPS OccuLtation and Passive reflection Experiment (GOLPE)) from NASA/JPL. The Magnetic Mapping Payload, (MMP) developed by the Danish Space Research Institute helps to better understand the Earth's magnetic field and related Sun -Earth interactions .Italian Star Tracker (IST) and Italian Navigation Experiment (INES) developed by the Italian Space Agency, constitute a technological payload that will permit testing a fully autonomous system for attitude and orbit determination.

Routine use of preventative medicines is advocated as part of responsible dog and cat ownership. However, it has been suggested that the number of owners in the United Kingdom (UK) using preventative medicines to protect their pets is in decline. The aim of this novel study was to use a qualitative methodology to explore the attitudes of pet owners and veterinary surgeons in the UK to using preventative medicine products in dogs and cats. Preventative medicine was defined as "a drug or any other preparation used to prevent disease, illness or injury." Semi-structured interviews were conducted by telephone with owners and veterinary surgeons who had recently participated in a preventative healthcare consultation. Thematic analysis of transcribed recordings of these interviews identified four themes. This paper reports the theme related to motivators and barriers to using preventative medicines. Owners' understanding varied widely about the importance of preventative medicines for pets, as did their confidence in the safety of prescription products. A good relationship with their veterinary surgeon or practice, seeing adverts on the television about specific diseases, advice from a breeder and having personally seen infected animals appeared to be motivators for owners to use preventative medicines. Concern about adverse events and uncertainty about the necessity of using preventative medicines were barriers. Owners who trusted their veterinary surgeons to advise them on preventative medicine products described little use of alternative information sources when making preventative medicine choices. However, owners who preferred to do their own research described reading online opinions, particular in relation to the safety of preventative medicines, which they found confusing. In contrast, veterinary surgeons described broad confidence in the safety and efficacy of prescription preventative medicines and described protection of pet health as a strong motivator for

Yolk sac development in lizards (Lacertilia: Scincidae): New perspectives on the egg of amniotes.

PubMed

Stewart, James R; Thompson, Michael B

2017-04-01

Embryos of oviparous reptiles develop on the surface of a large mass of yolk, which they metabolize to become relatively large hatchlings. Access to the yolk is provided by tissues growing outward from the embryo to cover the surface of the yolk. A key feature of yolk sac development is a dedicated blood vascular system to communicate with the embryo. The best known model for yolk sac development and function of oviparous amniotes is based on numerous studies of birds, primarily domestic chickens. In this model, the vascular yolk sac forms the perimeter of the large yolk mass and is lined by a specialized epithelium, which takes up, processes and transports yolk nutrients to the yolk sac blood vessels. Studies of lizard yolk sac development, dating to more than 100 years ago, report characteristics inconsistent with this model. We compared development of the yolk sac from oviposition to near hatching in embryonic series of three species of oviparous scincid lizards to consider congruence with the pattern described for birds. Our findings reinforce results of prior studies indicating that squamate reptiles mobilize and metabolize the large yolk reserves in their eggs through a process unknown in other amniotes. Development of the yolk sac of lizards differs from birds in four primary characteristics, migration of mesoderm, proliferation of endoderm, vascular development and cellular diversity within the yolk sac cavity. Notably, all of the yolk is incorporated into cells relatively early in development and endodermal cells within the yolk sac cavity align along blood vessels which course throughout the yolk sac cavity. The pattern of uptake of yolk by endodermal cells indicates that the mechanism of yolk metabolism differs between lizards and birds and that the evolution of a fundamental characteristic of embryonic nutrition diverged in these two lineages. Attributes of the yolk sac of squamates reveal the existence of phylogenetic diversity among amniote lineages

Molecular detection and in vitro antioxidant activity of S-allyl-L-cysteine (SAC) extracted from Allium sativum.

It is well known that Allium sativum has potential applications to clinical treatment of various cancers due to its remarkable ability in eliminating free radicals and increasing metabolism. An allyl-substituted cysteine derivative - S-allyl-L-cysteine (SAC) was separated and identified from Allium sativum. The extracted SAC was reacted with 1-pyrenemethanol to obtain pyrene-labelled SAC (Py-SAC) to give SAC fluorescence properties. Molecular detection of Py-SAC was conducted by steady-state fluorescence spectroscopy and time-resolved fluorescence method to quantitatively measure concentrations of Py-SAC solutions. The ability of removing 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl radical using Py-SAC was determined through oxygen radical absorbance capacity (ORAC). Results showed the activity of Py-SAC and Vitamin C (VC) with ORAC as index, the concentrations of Py-SAC and VC were 58.43 mg/L and 5.72 mg/L respectively to scavenge DPPH, and 8.16 mg/L and 1.67 mg/L to scavenge •OH respectively. Compared with VC, the clearance rates of Py-SAC to scavenge DPPH were much higher, Py-SAC could inhibit hydroxyl radical. The ability of removing radical showed a dose-dependent relationship within the scope of the drug concentration.

Anal sac tumours of the dog and their response to cytoreductive surgery and chemotherapy.

A retrospective study of anal sac tumours without pulmonary metastases, from the author's clinical records for the period July 1989 to July 2002, was conducted to establish the response to treatment with surgery and melphalan chemotherapy. Of 21 dogs with tumours of the anal sacs 19 had apocrine gland adenocarcinomas of anal sac origin, one had a benign papillary cystadenoma and another had a malignant melanoma. Two of the 19 dogs had bilateral anal sac adenocarcinomas. Ten of the 19 dogs with apocrine gland adenocarcinomas of anal sac origin had sublumbar lymphadenopathy. Five dogs were excluded by their owners from recommended treatment. Fourteen dogs with apocrine gland adenocarcinomas of anal sac origin were treated by surgical cytoreduction and chemotherapy with melphalan. Seven of the 14 dogs had regional lymph node metastases. Cytoreduction was by local excision of the anal sac in all 14 dogs and concurrent removal of the sublumbar retroperitoneal lymph nodes in the seven dogs with regional lymph node metastases. The median survival time of dogs with sublumbar nodal metastasis was 20 months and for dogs with tumour localised to the anal sac the median survival time was 29.3 months. There was no difference in median survival of those dogs with sublumbar metastases compared to those without. This study suggests there is a role for melphalan in the treatment of dogs with anal sac adenocarcinoma when combined with cytoreductive surgery, with treatment survival times and the local recurrence rate of the primary tumour comparing favourably with previously published treatment regimes.

In comp liance with the objectives established in the National Space Program, Argentina in Space 1997-2008 ((Plan Espacial Nacional, Argentina en el Espacio 1997-2008), the National Commission on Space Activities (Comisión Nacional de Actividades Espaciales - CONAE) undertook the design, construction, and launching of the SAC-C satellite in close collaboration with NASA. The purpose of this Mission is to carry out observations of interest both for the USA and Argentina, thus contributing effectively to NASA's Earth Science Program and to CONAE's National Space Program. The SAC-C is an international Earth observing satellite mission conceived as a partnership between CONAE and NASA, with additional support in instrumentation and satellite development from the Danish DSRI, the Italian ASI, the French CNES and the Brazilian INPE. A Delta II rocket successfully launched it on November 21st, 2000, from Vandenberg AFB, California, USA. Ten instruments on board the SAC-C perform different studies related to the ground and sea ecosystems, the atmosphere and the geomagnetic field. There are also technological experiments for determination of the satellite attitude and velocity as well as for the studies of the influence of space radiation on advanced electronic components . The inclusion of SAC-C in the AM Constellation, jointly with NASA satellites Landsat 7, EO 1 and Terra, is another example of important international cooperation which synergies the output of any single Mission. The Constellation has been working since March 2001 as a single mission and several cooperative activities have been undertaken including several jointly sponsored technical workshops and collaborative spacecraft navigation experiments. A flight campaign of the NASA AVIRIS instrument was performed in Argentine during January and February 2001, for calibration of SAC-C and EO 1 cameras and the development of joint scientific works.

Objective  The objective of this study was to investigate the prognostic value of a hernia sac in isolated congenital diaphragmatic hernia (CDH) with intrathoracic liver herniation ("liver-up"). Study Design  A retrospective study from the single tertiary center. Isolated "liver-up" CDH neonates referred to our institution between 2000 and 2015 were reviewed for the presence or absence of a hernia sac. Association between the presence of a hernia sac and survival was assessed. Results  Over the study period, there were 29 isolated CDH patients with "liver-up" who were treated, 7 (24%) had a sac, and 22 (76%) did not. Demographics were similar between groups. However, disease acuity, assessed from lower Apgar scores ( p  = 0.044), lower probability of survival ( p  = 0.037), and lower admission oxygenation ( p  = 0.027), was higher in neonates without a sac. Hospital survival was significantly higher for those with sac compared with those without (7/7, 100 vs. 7/22, 32%, p  = 0.002). Conclusion  The presence of a hernia sac may be associated with better survival for isolated "liver-up" CDH. As the presence of sac can be prenatally detected, it may be a useful marker to aid perinatal decision making. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Integration of Golgi trafficking and growth factor signaling by the lipid phosphatase SAC1

When a growing cell expands, lipids and proteins must be delivered to its periphery. Although this phenomenon has been observed for decades, it remains unknown how the secretory pathway responds to growth signaling. We demonstrate that control of Golgi phosphatidylinositol-4-phosphate (PI(4)P) is required for growth-dependent secretion. The phosphoinositide phosphatase SAC1 accumulates at the Golgi in quiescent cells and down-regulates anterograde trafficking by depleting Golgi PI(4)P. Golgi localization requires oligomerization of SAC1 and recruitment of the coat protein (COP) II complex. When quiescent cells are stimulated by mitogens, SAC1 rapidly shuttles back to the endoplasmic reticulum (ER), thus releasing the brake on Golgi secretion. The p38 mitogen-activated kinase (MAPK) pathway induces dissociation of SAC1 oligomers after mitogen stimulation, which triggers COP-I–mediated retrieval of SAC1 to the ER. Inhibition of p38 MAPK abolishes growth factor–induced Golgi-to-ER shuttling of SAC1 and slows secretion. These results suggest direct roles for p38 MAPK and SAC1 in transmitting growth signals to the secretory machinery. PMID:18299350

A perianal subcutaneous tumor involving the anal sac developed in an 8-year-old male mixed Labrador Retriever dog. Histologically, this tumor showed typical features of the solid-type carcinoma of the apocrine glands of the anal sac. However, neoplastic cells were immunoreactive for cytokeratin 8, chromogranin A, vasoactive intestinal peptide, neuron-specific enolase, and synaptophysin, and negative for S-100 protein, α-smooth muscle actin, vimentin, glucagon, insulin, somatostatin, carcinoembryonic antigen, serotonin, and parathyroid hormone-related protein. Considering the distribution of chromogranin A-positive cells within the anal sac apocrine glands, this tumor was diagnosed as neuroendocrine carcinoma originating from the apocrine glands of the anal sac.

Rationale: Patients with idiopathic bronchiectasis are predominantly female and have an asthenic body morphotype and frequent nontuberculous mycobacterial respiratory infections. They also demonstrate phenotypic features (scoliosis, pectus deformity, mitral valve prolapse) that are commonly seen in individuals with heritable connective tissue disorders. Objectives: To determine whether lumbar dural sac size is increased in patients with idiopathic bronchiectasis as compared with control subjects, and to assess whether dural sac size is correlated with phenotypic characteristics seen in individuals with heritable connective tissue disorders. Methods: Two readers blinded to diagnosis measured anterior–posterior and transverse dural sac diameter using L1–L5 magnetic resonance images of 71 patients with idiopathic bronchiectasis, 72 control subjects without lung disease, 29 patients with cystic fibrosis, and 24 patients with Marfan syndrome. We compared groups by pairwise analysis of means, using Tukey’s method to adjust for multiple comparisons. Dural sac diameter association with phenotypic and clinical features was also tested. Measurements and Main Results: The L1–L5 (average) anterior–posterior dural sac diameter of the idiopathic bronchiectasis group was larger than those of the control group (P < 0.001) and the cystic fibrosis group (P = 0.002). There was a strong correlation between increased dural sac size and the presence of pulmonary nontuberculous mycobacterial infection (P = 0.007) and long fingers (P = 0.003). A trend toward larger dural sac diameter was seen in those with scoliosis (P = 0.130) and those with a family history of idiopathic bronchiectasis (P = 0.149). Conclusions: Individuals with idiopathic bronchiectasis have an enlarged dural sac diameter, which is associated with pulmonary nontuberculous mycobacterial infection, long fingers, and family history of idiopathic bronchiectasis. These findings support our

Animal abuse and domestic violence are linked issues, and pet ownership is reported to play a crucial role in the choice to leave an abusive situation. Although veterinarians witness the effects of abuse and violence over the course of their careers, they have limited training regarding these issues. One mechanism for educating veterinary students while providing a service for victims of domestic violence is the creation of partnerships between domestic violence shelters and veterinary schools. These extracurricular programs can provide both care for pets belonging to victims of domestic violence and an educational platform for student participants. The goals of this study were to determine the prevalence and characteristics of domestic violence shelter partnerships (DVSPs) at North American veterinary teaching hospitals and to determine whether the presence of a DVSP was associated with increased awareness among veterinary students regarding animal abuse and domestic violence. Nine of 33 veterinary schools surveyed described a DVSP program. Students at schools with DVSPs associated with their veterinary teaching hospitals were significantly more likely to indicate that their awareness of the link between animal abuse and domestic violence had increased during veterinary school. Most veterinary students reported that they felt poorly prepared to handle domestic violence and animal abuse issues in the workplace. This study indicates that extracurricular DVSPs are a viable means of educating veterinary students regarding domestic violence and animal abuse. A need for improved education on these topics in veterinary schools across North America is identified.

Squamous cell carcinoma of the anal sac in five dogs.

PubMed

Esplin, D G; Wilson, S R; Hullinger, G A

2003-05-01

Tumors of the perianal area of dogs are common and include multiple tumor types. Whereas perianal adenomas occur often, adenocarcinomas of the apocrine glands of the anal sac occur less frequently. A review of the literature revealed no reports of squamous cell carcinomas arising from the epithelial lining of the anal sac. Squamous cell carcinomas originating from the lining of the anal sac were diagnosed in five dogs. Microscopically, the tumors consisted of variably sized invasive nests and cords of epithelial cells displaying squamous differentiation. Four of the five dogs were euthanatized because of problems associated with local infiltration by the tumors. In the fifth dog, there was no evidence of tumor 7 months after surgical removal, but further follow up was not available.

To evaluate the influence of naringin on PMMA-induced osteoclastic bone resorption using the mouse air sacs model. Total 48 female Balb/c mices with the age of 8 to 10 weeks were chosen in the study. Air were injected into the back in 32 mices and formed the air sacs, 6 d later, the skulls (originated from other 16 mices) were implanted to the air sacs. Thirty-two animals were divided into naringin treatment group (with 2 concentrations of 150 mg/kg and 30 mg/ kg) , DMSO group and PBS blank group, 8 animals in each group. Polymethylmethacrylate (PMMA) particles were injected into the air sacs in naringin treatment groups and DMSO group so as to irritate inflammatory reaction. Naringin with 2 concentrations of 150 mg/kg and 30 mg/kg were dissolved in DMSO of 0.2 ml, and were injected into air sacs, respectively. In PBS black group, no stimulation with PMMA particles, only injected PBS, and in DMSO group, injected DMSO without naringin. Tartrate resistant acid phosphatase (TRAP), Ca2+ release, modified Masson stain and histological analysis were performed on the 7th day after stimulation. Compared with DMSO group, naringin treatment group's cellular infiltration decreased (P < 0.01); concentration of 150 mg/kg was better than that of concentrations of 30 mg/kg (8.90 ± 1.75 vs 15.23 ± 1.86). Naringin can decrease calcium release in the lavage of the air sacs bone resorption model, especially obvious in naringin with concentration of 150 mg/kg. Naringin can ameliorate the inflammatory reaction and the subsequent bone resorption (including bone collagen loss, TRAP positive cells amount and so on) in air sacs with bone implant and PMMA particles. Naringin with concentration of 150 mg/kg appeared to be an optimal dosage to deliver the therapeutic effects. Naringin inhibits PMMA-induced osteoclastogenesis and ameliorates the PMMA-associated inflammatory reaction and the subsequent bone resorption.

2004-01-01

This article presents the results of an Internet-based review conducted in January and February 2003 to assess the educational opportunities available in veterinary public health, epidemiology, and preventive medicine at the 27 veterinary schools in the United States. Most professional veterinary curricula are designed to train students for careers as highly qualified private practitioners, although there is an increased need for veterinary perspectives and contributions in the public health sector. The future of veterinary public health relies on the opportunities available in education to teach and encourage students to pursue a career of public service. The results of this review indicate the availability of a wide variety of required courses, electives, and post-graduate training programs to veterinary students in the United States. Veterinary students are exposed to a median of 60 hours of public health, epidemiology, and preventive medicine in required stand-alone courses in these areas. Four veterinary schools also have required rotations for senior students in public health, preventive medicine, or population medicine. Contact time for required public health, epidemiology, and preventive medicine courses ranges from 30 to 150 contact hours. Advanced training was available in these subjects at 79% of the 27 schools. Greater collaboration between veterinary schools, schools of public health, and the professional public health community will increase exposure to and opportunities in public health to all future veterinarians.

1985-01-01

Deposition of anal-sac secretions by captive wolves was investigated by a labelling technique using protein-bound iodine125 and food dye. Wolves deposited secretions on some but not all scats. Adult males, especially the alpha male, deposited anal-sac secretions more frequently while defecating than did females or juveniles. Secretions sometimes also were deposited independently of defecation, suggesting a dual role in communication by these substances.

Nordic rattle: the hoarse vocalization and the inflatable laryngeal air sac of reindeer (Rangifer tarandus)

2007-01-01

Laryngeal air sacs have evolved convergently in diverse mammalian lineages including insectivores, bats, rodents, pinnipeds, ungulates and primates, but their precise function has remained elusive. Among cervids, the vocal tract of reindeer has evolved an unpaired inflatable ventrorostral laryngeal air sac. This air sac is not present at birth but emerges during ontogenetic development. It protrudes from the laryngeal vestibulum via a short duct between the epiglottis and the thyroid cartilage. In the female the growth of the air sac stops at the age of 2–3 years, whereas in males it continues to grow up to the age of about 6 years, leading to a pronounced sexual dimorphism of the air sac. In adult females it is of moderate size (about 100 cm3), whereas in adult males it is large (3000–4000 cm3) and becomes asymmetric extending either to the left or to the right side of the neck. In both adult females and males the ventral air sac walls touch the integument. In the adult male the air sac is laterally covered by the mandibular portion of the sternocephalic muscle and the skin. Both sexes of reindeer have a double stylohyoid muscle and a thyroepiglottic muscle. Possibly these muscles assist in inflation of the air sac. Head-and-neck specimens were subjected to macroscopic anatomical dissection, computer tomographic analysis and skeletonization. In addition, isolated larynges were studied for comparison. Acoustic recordings were made during an autumn round-up of semi-domestic reindeer in Finland and in a small zoo herd. Male reindeer adopt a specific posture when emitting their serial hoarse rutting calls. Head and neck are kept low and the throat region is extended. In the ventral neck region, roughly corresponding to the position of the large air sac, there is a mane of longer hairs. Neck swelling and mane spreading during vocalization may act as an optical signal to other males and females. The air sac, as a side branch of the vocal tract, can be considered as

Teaching veterinary parasitology.

PubMed

Verster, A

1994-08-01

The history of parasitology and the teaching of veterinary parasitology in South Africa are reviewed briefly. Courses in veterinary parasitology are presented at the faculties of veterinary science at the University of Pretoria and the Medical University of South Africa as well as at the Pretoria Technicon. At the University of Pretoria, the three disciplines of veterinary parasitology, entomology, helminthology and protozoology, are covered in 330 core lectures; from 13 to 40% of the contact time is devoted to practical classes. Teaching veterinary parasitology is both labour intensive and costly, viz. R1700 (US$570) per student per annum. Such costs are justified by the R148.8 million (US$49.6 million) spent every year in South Africa on anthelmintics, ectoparasiticides and vaccines to control parasites. Veterinary parasitology is a dynamic subject and the curriculum must be revised regularly to incorporate new information. Because the parasite faunas are so diverse no single textbook can satisfy the requirements of the various institutions worldwide which teach the subject, with the result that extensive use is made of notes. In Australia and in Europe, ticks and tick-borne diseases are less important than they are in Africa; consequently insufficient space is devoted to them in textbooks to satisfy the requirements of the subject in African countries. Parasite control under extensive and intensive conditions is dealt with adequately at the University of Pretoria, but increasing emphasis will be given to small-scale farming systems, particularly if alternative food animals are to be kept.

It is important for veterinary administrators to apply knowledge bases from other fields to their own unique administrative needs. For example, although some resources are written for business managers, the discussions of four key management competency areas, guidelines for mastering these skills, organizational assessment tools, and other self-help tools may provide interesting food-for-thought for veterinary administrators.(76) In developing their own administrative styles, administrators should seek to apply those principles that seem to intuitively fit with their personal research styles, work situations, managerial styles, administrative preferences, and unique organizational culture. Through strengthening their liaisons with community and university business programs, counseling agencies, employee assistance programs, and psychology researchers, administrators can continue to be exposed to and benefit from new paradigms for consideration in veterinary medical environments. Through these liaisons, the unique needs of veterinary medical environments are also communicated to individuals within the fields of psychology and business, thus stimulating new research that specifically targets veterinary medical environment leadership issues. Each field has unique contributions to help veterinary administrators work toward creating veterinary medical environments that are creative, energetic, visionary, pragmatic, and highly marketable in order to help administrators recruit and nurture the best and brightest veterinary researchers, teachers, and clinicians.

Background Transplanting pancreatic islets is of significant interest for type 1 diabetes mellitus. After intraportal injection of islets, inferior engraftment and eventual loss of transplanted islets constitute major limitations. Therefore, alternative approaches will be helpful. Here, we evaluated in animals whether an isolated venous sac would support survival of transplanted islets, along with correction of hyperglycemia. Methods Pancreatic islets isolated from adult Lewis rats were transplanted either into an isolated venous sac made from lumbar vein or into the portal vein of syngeneic rats. The integrity and vascular organization of the venous sac was determined by studies of the local microcirculation. The engraftment, survival, and function of transplanted islets were analyzed by histology, including endocrine function in situ and by glycemic control in rats with streptozotocin-induced diabetes. Results Transplanted islets showed normal morphology with insulin expression in isolated venous sac during the long term. Transplanted islets received blood supply from vasa vasorum and had access to drainage through venous tributaries in the venous sac. This resulted in restoration of euglycemia in diabetic rats. Removal of islet graft-bearing venous sac in diabetic rats led to recurrence of hyperglycemia. By contrast, euglycemia was not restored in rats treated by intraportal transplantation of islets. Conclusions We demonstrated that pancreatic islets successfully engrafted and functioned in the isolated venous sac with ability to restore euglycemia in diabetic rats. Therefore, the isolated venous sac offers a new site for transplantation of pancreatic islets. This would be clinically beneficial as an alternative to intrahepatic islet transplantation.

Survey of owner motivations and veterinary input of owners feeding diets containing raw animal products

PubMed Central

Willis, Susan; Shepherd, Megan L.

2017-01-01

Background The practice of feeding of diets containing raw animal products (RAP) to pets (dogs and cats) is discouraged by veterinary organizations and governmental public health organizations. Nevertheless, the practice of feeding RAP to pets is increasing in popularity. Pet owner motivations for feeding RAP diets to pets have not been explored and the benefits of RAP diets remain largely anecdotal. We hypothesized that pet owners feeding RAP diets would not rely on veterinary advice in choosing their pet’s diet. We also hypothesized that these owners would have lower levels of trust in veterinary advice with respect to nutrition relative to pet owners not feeding RAP. Methods An anonymous web-based survey was developed to identify pet owner motivations for feeding RAP diets, and to characterize the veterinarian-client relationships of individuals feeding RAP diets. Results There were 2,337 respondents and 2,171 completed surveys. Of survey respondents, 804 reported feeding RAP at the time of the survey. While 20% of pet owners feeding RAP relied on online resources to determine what or how much RAP to feed, only 9% reported consulting with a veterinarian in making decisions about feeding RAP. Pet owners feeding RAP reported lower levels of trust in veterinary advice both ‘in general’ and ‘with respect to nutrition’ than pet owners not feeding RAP. Most pet owners reported that a discussion regarding their pet’s nutrition does not occur at every veterinary appointment. Discussion Pet owners feeding a RAP diet have lower trust in veterinary advice than pet owners not feeding a RAP diet. Owners feeding RAP are more reliant on online resources than their own veterinarian in deciding what and how much RAP to feed. Pet owners perceive that nutrition is not discussed at most veterinary appointments. Therefore, there is room for improvement in the veterinarian-client communication with regards to nutrition.

2009-01-01

The goal of this research is to develop a 3D finite element (FE) model of a left ventricular assist device (LVAD) to predict stresses in the blood sac. The hyperelastic stress-strain curves for the segmented poly(ether polyurethane urea) blood sac were determined in both tension and compression using a servo-hydraulic testing system at various strain rates. Over the range of strain rates studied, the sac was not strain rate sensitive, however the material response was different for tension versus compression. The experimental tension and compression properties were used in a FE model that consisted of the pusher plate, blood sac and pump case. A quasi-static analysis was used to allow for nonlinearities due to contact and material deformation. The 3D FE model showed that blood sac stresses are not adversely affected by the location of the inlet and outlet ports of the device and that over the systolic ejection phase of the simulation the prediction of blood sac stresses from the full 3D model and an axisymmetric model are the same. Minimizing stresses in the blood sac will increase the longevity of the blood sac in vivo. PMID:19131267

Cells of the connective tissue differentiate and migrate into pollen sacs

In angiosperms, archesporial cells in the anther primordium undergo meiosis to form haploid pollen, the sole occupants of anther sacs. Anther sacs are held together by a matrix of parenchyma cells, the connective tissue. Cells of the connective tissue are not known to differentiate. We report the differentiation of parenchyma cells in the connective tissue of two Gordonia species into pollen-like structures (described as pseudopollen), which migrate into the anther sacs before dehiscence. Pollen and pseudopollen were distinguishable by morphology and staining. Pollen were tricolpate to spherical while pseudopollen were less rigid and transparent with a ribbed surface. Both types were different in size, shape, staining and surface architecture. The ratio of the number of pseudopollen to pollen was 1:3. During ontogeny in the connective tissue, neither cell division nor tetrad formation was observed and hence pseudopollen were presumed to be diploid. Only normal pollen germinated on a germination medium. Fixed preparations in time seemed to indicate that pseudopollen migrate from the connective tissue into the anther sac.

Antimicrobial resistance has emerged in recent years as a significant public health threat, which requires both an ethical and a scientific approach. In a recent Policy Delphi study, on-farm use of antimicrobials was a key concern identified by veterinary professionals in Ireland. In this case study (the second in a series of three resulting from a research workshop exploring the challenges facing the veterinary profession in Ireland; the other two case studies investigate clinical veterinary services and emergency/casualty slaughter certification) we aim to provide a value-based reflection on the constraints and possible opportunities for responsible use of veterinary antimicrobials in Ireland. Using a qualitative focus group approach, this study gathered evidence from relevant stakeholders, namely veterinarians working in public and private organisations, a representative from the veterinary regulatory body, a dairy farmer and a general medical practitioner. Three overarching constraints to prudent on-farm use of veterinary antimicrobials emerged from the thematic analysis: 'Defective regulations', 'Lack of knowledge and values' regarding farmers and vets and 'Farm-centred concerns', including economic and husbandry concerns. Conversely, three main themes which reflect possible opportunities to the barriers were identified: 'Improved regulations', 'Education' and 'Herd health management'. Five main recommendations arose from this study based on the perspectives of the study participants including: a) the potential for regulatory change to facilitate an increase in the number of yearly visits of veterinarians to farms and to implement electronic prescribing and shorter validity of prescriptions; b) a 'One Health' education plan; c) improved professional guidance on responsible use of veterinary antimicrobials; d) improved on-farm herd health management practices; and e) the promotion of a 'One Farm-One Vet' policy.

Reproductive technologies are widely used in cattle, although many are associated with high-embryonic mortality, especially during early gestation, when the yolk sac undergoes macroscopic changes in structure. We hypothesized that vasculogenesis and angiogenesis are affected, thereby affecting embryonic and placental differentiation. To test this, we studied yolk sac development and gene expression of the vascular endothelial growth factor system (VEGF-A, VEGFR-1/Flt-1, VEGFR-2/KDR). Samples from Days 25 to 40/41 of pregnancy from control cattle (n = 8) and from pregnancies established with IVF, (n = 7) or somatic cell nuclear transfer/clones (n = 5) were examined by histology, immunohistochemistry, and quantitative reverse transcriptase PCR. Yolk sacs in IVF- and nuclear transfer-derived pregnancies were immature. Development of villi was sparse in IVF yolk sacs, whereas vascularization was barely formed in clones and was associated, in part, with thin or interrupted endothelium. Transcript levels of the genes characterized exceed minimum detection limits for all groups, except in the mentioned clone with interrupted endothelium. Levels of mRNA for VEGF-A and VEGFR-2 were significantly higher in IVF yolk sacs. Clones had substantial individual variation in gene expression (both upregulation and downregulation). Our data confirmed the broad range in expression of VEGF genes. Furthermore, overexpression in IVF yolk sacs may compensate for an immature yolk sac structure, whereas in clones, patchy expression may cause structural alterations of blood vessels. In conclusion, we inferred that disturbances of yolk sac vasculature contributed to increased early embryonic mortality of bovine pregnancies established with reproductive technologies.

The effect of pigeon yolk sac fluid on the growth behavior of calcium carbonate crystals.

Song, Juan; Cheng, Haixia; Shen, Xinyu; Tong, Hua

2015-03-01

Previous experiments have proved that thermodynamically unstable calcium carbonate vaterite can exist for long periods in the yolk sac of a pigeon embryo. The aim of this article was to demonstrate the effect of in vitro mineralization of yolk sac fluid on calcium carbonate by direct precipitation. Experiments were conducted using pigeon yolk sac fluid and using lecithin extracted from pigeon yolk sac fluid as a control to investigate the regulating effects of the organic components in the embryo on the formation of the calcium carbonate precipitate. Multiple characterization methods were employed to study the various morphological patterns, sizes, crystal growth, and crystal phase transformations of the calcium carbonate precipitates as regulated by the yolk sac fluid extracted at different stages of incubation. The experimental results demonstrate that as the incubation proceeds towards the later stages, the composition and environmental features of the yolk sac fluid become more favorable for the formation of relatively unstable calcium carbonate phases with high energies of the vaterite state. The experiments conducted with extracted lecithin as the template for crystal growth yielded similar results. A large amount of organic molecules with polar functional groups carried by the yolk sac fluid have strong effects and can both initially induce the crystallization and regulate the aggregation of calcium carbonate. Furthermore, this regulation process is found to be closely related to the lecithin contained in yolk sac fluid. These observations confirm the changes in yolk sac fluid composition during incubation have significant effects on the production of vaterite, which implicates the calcium transport during embryo growth. © 2015 Poultry Science Association Inc.

Studies have indicated the importance of business education in improving the income level attained by veterinarians and the quality of service they provide. The Veterinary Business Management Association (VBMA), a national organization of veterinary students, has the potential to augment veterinary curricula by providing additional education to help ensure professional success. Local chapters at 27 of the 28 veterinary colleges in the United States (as of 2007) supplement the curriculum by focusing on business topics. A national governing board oversees the chapters, helping to ensure that high-quality educational programs are conducted and providing a conduit for communication.

Innate immune defense in the inner ear - mucines are expressed by the human endolymphatic sac.

Møller, Martin N; Kirkeby, Svend; Cayé-Thomasen, Per

2017-02-01

The human endolymphatic sac has been shown recently to have immunological capacities and has thus been proposed as the main entity protecting the inner ear from pathogen invasion, equivalent to mucosa-associated lymphoid tissue (MALT). Although the sac expresses molecules of the innate immune system, the potential expression of members of the important mucin family has not been detailed. Thus, this paper explores endolymphatic sac expression of a number of mucins and mucin precursors. Twelve fresh tissue samples from the human endolymphatic sac were obtained during translabyrinthine surgery. The expression of Mucin 1, 2, 5B/AC and 16, as well as the core structure elements (mucin precursors) T-antigen, Tn-antigen and Sialyl-Tn-antigen was investigated by immunohistochemistry. The endolymphatic sac epithelium expressed MUC1 (both apically towards the endolymphatic sac (ES) lumen and basally towards the capillary network), MUC 16 and Tn-antigen. There was no labeling after incubation with antibodies against T-antigen, sialyl-Tn-antigen, MUC2 and MUC5B/AC. We conclude that the human endolymphatic sac epithelium expresses a number of mucin molecules, which supports the hypothesis of the sac as the primary immunological tissue structure of the inner ear, equivalent to MALT in other organs. The mucins may also play a role in the formation and continuous homeostasis of the inner ear fluids, as well as the pathogenesis of Meniere's disease. © 2016 Anatomical Society.

Involvement of Sac1 phosphoinositide phosphatase in the metabolism of phosphatidylserine in the yeast Saccharomyces cerevisiae.

PubMed

Tani, Motohiro; Kuge, Osamu

2014-04-01

Sac1 is a phosphoinositide phosphatase that preferentially dephosphorylates phosphatidylinositol 4-phosphate. Mutation of SAC1 causes not only the accumulation of phosphoinositides but also reduction of the phosphatidylserine (PS) level in the yeast Saccharomyces cerevisiae. In this study, we characterized the mechanism underlying the PS reduction in SAC1-deleted cells. Incorporation of (32) P into PS was significantly delayed in sac1∆ cells. Such a delay was also observed in SAC1- and PS decarboxylase gene-deleted cells, suggesting that the reduction in the PS level is caused by a reduction in the rate of biosynthesis of PS. A reduction in the PS level was also observed with repression of STT4 encoding phosphatidylinositol 4-kinase or deletion of VPS34 encoding phophatidylinositol 3-kinase. However, the combination of mutations of SAC1 and STT4 or VPS34 did not restore the reduced PS level, suggesting that both the synthesis and degradation of phosphoinositides are important for maintenance of the PS level. Finally, we observed an abnormal PS distribution in sac1∆ cells when a specific probe for PS was expressed. Collectively, these results suggested that Sac1 is involved in the maintenance of a normal rate of biosynthesis and distribution of PS. Copyright © 2014 John Wiley & Sons, Ltd.

2015-01-01

There is a paucity of research regarding veterinary students' attitudes toward the rural environment and rural veterinary practice and how these attitudes might change over the course of a veterinary medicine program that includes rural clinical experience. Using a 23-item questionnaire, attitudes toward rural lifestyle, rural work-life balance, opportunities for career and skill development in rural veterinary practice, and inter-professional teamwork in the rural environment were assessed at the beginning and completion of a four-year veterinary medicine program. Eighty-six students (74.4% female) were included in this Canadian study over a six-year period. Thirty-one participants (36.1%) were rural students. Overall, students' attitudes toward the rural lifestyle, rural work-life balance, and inter-professional teamwork in rural veterinary practice all significantly decreased (p<.001) over the course of the program. As compared to urban students, rural students had significantly higher rural lifestyle scores at both the beginning (p<.001) and end (p<.01) of the veterinary medicine program. A less positive attitude toward living and working in a rural environment could influence students to exclude rural veterinary practice as a career choice. Rural clinical experiences designed to sustain or increase veterinary student interest in rural practice may not be sufficient to support positive rural attitudes. Given the demand for rural veterinary services in developed countries, the implications of this study may extend beyond Canada.

District, state or regional veterinary diagnostic laboratories.

PubMed

Gosser, H S; Morehouse, L G

1998-08-01

The district, regional or state laboratory is the local laboratory to which veterinarian practitioners usually submit samples, and consequently these laboratories are usually the first to observe a suspected disease problem. In most countries, these laboratories are under the jurisdiction of the State or region in which they are located. In the United States of America (USA), most veterinary diagnostic laboratories are State-associated and operate under the aegis of either the State Department of Agriculture or a university. The national laboratory provides reference assistance to the State laboratories. In the USA, the national Laboratory (the National Veterinary Services Laboratories) acts as a consultant to confirm difficult diagnoses and administer performance tests for State-associated laboratories. District, state or regional laboratories need to share information regarding technological advances in diagnostic procedures. This need was met in the USA by the formation of the American Association of Veterinary Laboratory Diagnosticians (AAVLD) in the late 1950s. Another requirement of district, state or regional diagnostic laboratories is a method to confirm quality assurance, which was fulfilled in the USA by an accreditation programme established through the AAVLD. The Accreditation Committee evaluates laboratories (on request) in terms of organisation, personnel, physical facilities and equipment, records, finance and budget. Those laboratories which meet the standards as established in the 'Essential Requirements for Accreditation' are given accreditation status, which indicates that they have the expertise and facilities to perform tests on food-producing animals for shipment in national or international commerce and on companion, laboratory or zoo animals. While confidentiality of test records is most important, it is becoming necessary to release certain types of animal disease test information if a country is to participate in the exportation of animals

Development of the endolymphatic sac in chick embryos, with reference to the degradation of otoconia

NASA Technical Reports Server (NTRS)

Yoshihara, T.; Kaname, H.; Narita, N.; Ishii, T.; Igarashi, M.; Fermin, C. D.

1992-01-01

The endolymphatic sac of chick embryos (from embryonic day 7 to 1-day-old chicks) was studied light- and electron-microscopically. At stage 30-31 (embryonic day 7-7.5), the epithelial cells of the endolymphatic sac were cuboidal to columnar in shape. Microvilli were relatively well developed. The intercellular space was wide. In the endolymphatic space of the endolymphatic sac, varying shapes and sizes of otoconia-like bodies were often observed. Intracytoplasmic phagosomes containing these bodies were rarely found. After stage 37 (embryonic day 11), otoconia-like bodies in the endolymphatic sac decreased in number and size. They were almost the same as the otoconia in the macular organs, ultrastructurally. These findings indicate that the endolymphatic sac of the chick embryos may possess the function of otoconial degradation and removal of calcium from otoconia.

The responsibilities of veterinary educators in responding to emerging needs in veterinary medicine.

PubMed

Halliwell, R E W

2009-08-01

It is an unfortunate fact that not only has veterinary education failed to adapt in the face of likely future needs, but it has also failed to respond to societal changes that have already taken place and that have affected the requirements for veterinary services and veterinary capability. The responsibility is primarily that of educators, although vision and foresight require a co-ordinated approach involving national and international veterinary organisations. Once it is accepted by all parties that change is essential, the implementation will fail unless there is a unified programme involving the schools and colleges, the accrediting agencies, the licensing authorities, governments, the professional organisations and corporate veterinary medicine. All have a role to play, and any one can readily block progress. A unified approach is an absolute requirement. The developed countries must take a leading role, but the issues are global, and ways must be found to facilitate change in all parts of the world. Disease knows no boundaries, and any strategy is only as strong as its weakest link.

Contractual considerations in veterinary practice.

Veterinary medicine is a profession based on contract. Many aspects of veterinary practice involve legally enforceable contract obligations. Legal rules established by statutes or court cases govern contract formation, interpretation, and enforcement. This article explains several legal principles governing contract law and applies some of these principles to common contractual settings in veterinary medicine.

Seismic Analysis Code (SAC): Development, porting, and maintenance within a legacy code base

NASA Astrophysics Data System (ADS)

Savage, B.; Snoke, J. A.

2017-12-01

The Seismic Analysis Code (SAC) is the result of toil of many developers over almost a 40-year history. Initially a Fortran-based code, it has undergone major transitions in underlying bit size from 16 to 32, in the 1980s, and 32 to 64 in 2009; as well as a change in language from Fortran to C in the late 1990s. Maintenance of SAC, the program and its associated libraries, have tracked changes in hardware and operating systems including the advent of Linux in the early 1990, the emergence and demise of Sun/Solaris, variants of OSX processors (PowerPC and x86), and Windows (Cygwin). Traces of these systems are still visible in source code and associated comments. A major concern while improving and maintaining a routinely used, legacy code is a fear of introducing bugs or inadvertently removing favorite features of long-time users. Prior to 2004, SAC was maintained and distributed by LLNL (Lawrence Livermore National Lab). In that year, the license was transferred from LLNL to IRIS (Incorporated Research Institutions for Seismology), but the license is not open source. However, there have been thousands of downloads a year of the package, either source code or binaries for specific system. Starting in 2004, the co-authors have maintained the SAC package for IRIS. In our updates, we fixed bugs, incorporated newly introduced seismic analysis procedures (such as EVALRESP), added new, accessible features (plotting and parsing), and improved the documentation (now in HTML and PDF formats). Moreover, we have added modern software engineering practices to the development of SAC including use of recent source control systems, high-level tests, and scripted, virtualized environments for rapid testing and building. Finally, a "sac-help" listserv (administered by IRIS) was setup for SAC-related issues and is the primary avenue for users seeking advice and reporting bugs. Attempts are always made to respond to issues and bugs in a timely fashion. For the past thirty-plus years

Termination of pregnancy at very early gestation without visible yolk sac on ultrasound.

PubMed

Heller, Rebecca; Cameron, Sharon

2015-04-01

Requests for termination of pregnancy (TOP) at very early gestation (≤6 weeks) can prove challenging for abortion services as the ultrasound feature usually accepted as definitive evidence of an intrauterine pregnancy (IUP), the presence of a yolk sac within a gestational sac, may not yet be evident. In 2011 the Edinburgh TOP service introduced a protocol permitting women to proceed to treatment without further investigations provided that ultrasound showed the features of an eccentrically placed gestational sac (≥3 mm) with a decidual reaction, and there were no signs, symptoms or risk factors for ectopic pregnancy. A retrospective audit was conducted of outcomes of women presenting for TOP at ≤6 weeks' gestation over a 2-year period using the hospital computerised database. A total of 1155 women presented for TOP with an ultrasound gestational age of ≤6 weeks. Of these, 1030 (89%) had ultrasound evidence of a yolk sac. Eighty-seven women (7.5%) had an eccentrically placed gestational sac with a decidual reaction. All 87 women fulfilled our criteria to proceed to medical TOP, and 66 did so. In the remaining 21 cases, further investigations were performed before they proceeded to medical TOP. Two (0.17%) medical TOPs failed, both in women whose initial ultrasound had shown a yolk sac. Women with ultrasound features consistent with a very early IUP (≥3 mm eccentrically placed gestational sac with a decidual reaction) and without signs, symptoms or risk factors for ectopic pregnancy can proceed directly to medical TOP without the need for delay for further ultrasonography.

Traditionally, hernia sac ligation during inguinal hernia repair is considered mandatory to prevent postoperative development of hernia. However, ligation may induce postoperative pain. The aim of this study was to evaluate the outcomes of hernia sac ligation after inguinal hernia repair. We conducted a systematic review and meta-analysis of randomized controlled trials to investigate the outcomes of hernia sac ligation for open or laparoscopic inguinal hernia repair. Incidence of hernia recurrence was assessed following the surgery. The secondary outcomes included pain scores and postoperative complications. Five trials were selected and their results were summarized. These 5 trials were published between 1984 and 2014, and the sample sizes ranged from 50 to 467 patients. Four trials had recruited patients with inguinal hernia who underwent open repair, and one study enrolled patients who underwent laparoscopic procedures. We observed no difference in the incidence of hernia recurrence and postoperative complications between the sac ligation and nonligation groups. Postoperatively, the intensity of pain was significantly higher in the ligation group than in the nonligation group at Day 7 (Weight mean difference 1.46; 95% confident interval: 0.98-1.95). Hernia sac ligation was associated with higher postoperative pain, and did not show any benefit over sac nonligation regarding the incidence of recurrence and postoperative complications in patients undergoing open tension-free mesh repair or laparoscopic procedures.

Direct Effects of Microalgae and Protists on Herring (Clupea harengus) Yolk Sac Larvae

PubMed Central

Illing, Björn; Moyano, Marta; Niemax, Jan; Peck, Myron A.

2015-01-01

This study investigated effects of microalgae (Rhodomonas baltica) and heterotrophic protists (Oxyrrhis marina) on the daily growth, activity, condition and feeding success of Atlantic herring (Clupea harengus) larvae from hatch, through the end of the endogenous (yolk sac) period. Yolk sac larvae were reared in the presence and absence of microplankton and, each day, groups of larvae were provided access to copepods. Larvae reared with microalgae and protists exhibited precocious (2 days earlier) and ≥ 60% increased feeding incidence on copepods compared to larvae reared in only seawater (SW). In the absence and presence of microalgae and protists, life span and growth trajectories of yolk sac larvae were similar and digestive enzyme activity (trypsin) and nutritional condition (RNA-DNA ratio) markedly declined in all larvae directly after yolk sac depletion. Thus, microplankton promoted early feeding but was not sufficient to alter life span and growth during the yolk sac phase. Given the importance of early feeding, field programs should place greater emphasis on the protozooplankton-ichthyoplankton link to better understand match-mismatch dynamics and bottom-up drivers of year class success in marine fish.

Superficial veterinary mycoses.

PubMed

Bond, Ross

2010-03-04

Dermatophytes are significant pathogens in animal health due to their zoonotic potential, the economic consequences of infection in farm animal and fur production systems, and the distressing lesions they cause in small domestic pets. Malassezia spp are normal commensal and occasional pathogens of the skin of many veterinary species. Malassezia pachydermatis is a very common cause of otitis and pruritic dermatitis in dogs but is of less importance in other veterinary species. Dermatophytosis, and Malassezia otitis and dermatitis, represent the superficial mycoses of greatest significance in companion and farm animal health. Although the dermatophytes and Malassezia spp both exist in the stratum corneum of mammalian skin, there are important differences in the epidemiology, pathogenesis, and clinical consequences of infection. Dermatophytes are significant due to their zoonotic potential, the economic consequences of infection in farm animal and fur production systems, and the concern for owners of pets with inflammatory skin disease that is sometimes severe. Malassezia spp are normal commensals and occasional pathogens of the skin for many veterinary species, and M pachydermatis is a very common cause of otitis and pruritic dermatitis in dogs. This chapter will focus on the epidemiologic, clinical, diagnostic, and therapeutic aspects of dermatophytosis and Malassezia dermatitis in veterinary species. There are generally only sporadic reports of other superficial mycoses, such as candidiasis, piedra, and Rhodotorula dermatitis in veterinary medicine, and these are not included here.

Comparison of veterinary drugs and veterinary homeopathy: part 1

PubMed Central

Lees, P.; Pelligand, L.; Whiting, M.; Chambers, D.; Toutain, P-L.; Whitehead, M. L.

2017-01-01

For many years after its invention around 1796, homeopathy was widely used in people and later in animals. Over the intervening period (1796-2016) pharmacology emerged as a science from Materia Medica (medicinal materials) to become the mainstay of veterinary therapeutics. There remains today a much smaller, but significant, use of homeopathy by veterinary surgeons. Homeopathic products are sometimes administered when conventional drug therapies have not succeeded, but are also used as alternatives to scientifically based therapies and licensed products. The principles underlying the veterinary use of drug-based and homeopathic products are polar opposites; this provides the basis for comparison between them. This two-part review compares and contrasts the two treatment forms in respect of history, constituents, methods of preparation, known or postulated mechanisms underlying responses, the legal basis for use and scientific credibility in the 21st century. Part 1 begins with a consideration of why therapeutic products actually work or appear to do so. PMID:28801498

Primary Mucoepidermoid Carcinoma of the Lacrimal Sac -  a Case Report and Literature Review.

PubMed

Janakiram, T N; Sagar, S; Sharma, S B; Subramaniam, V

Lacrimal sac tumors are very rare and are often missed because patients present with features consistent with chronic dacryocystitis. Squamous cell carcinoma is the common-est lacrimal sac malignancy. Although primary mucoepidermoid carcinomas of the lacrimal sac are rare, they are locally aggressive. Furthermore, their proximity to vital structures and the skull base makes them potentially life-threatening. Multidisciplinary management is required, and wide excision followed by chemoradiation is the recommended treatment. Here, we report a 65-year-old male who presented with watering eyes and a mass in the region of the medial canthus. A dia-gnosis of primary mucoepidermoid carcinoma of the lacrimal sac was made, and the case was managed successfully with radical surgery and reconstruction. The tumor was resected using the extended Lynch-Howarth incision and the resulting defect was reconstructed using a forehead flap. Histopathological examination of the excised specimen revealed mucoepidermoid carcinoma. Immunohistochemical analysis revealed that the speci-men was positive for epithelial growth factor receptor and Ki-67 protein. The patient was referred for post-operative chemoradiation. The literature is reviewed and pathological features, including immunohistochemistry are discussed. Primary mucoepidermoid carcinoma of the lacrimal sac is a rare, locally aggressive tumor that is often mistaken for dacryocystitis. The treatment of choice is radical surgery followed by chemoradiation. lacrimal sac -  mucoepidermoid carcinoma -  epithelial growth factor receptor -  Ki-67 protein.

WAAVP/Pfizer award for excellence in teaching veterinary parasitology: teaching of veterinary parasitology--quo vadis?

PubMed

Eckert, J

2000-02-29

Some thoughts on training and recruitment of academic teachers and future trends in teaching veterinary parasitology are presented with emphasis on the European situation. It is underlined that research is an indispensable basis for academic teaching. Besides a broad scientific background of the teacher, motivation and teaching methods are also important. Many academic teachers do not receive formal training in teaching methods. In order to improve future education, training of staff members in teaching methods should be promoted. Quality control of teaching and research, already established in many schools, should generally be introduced. Teaching is mostly underestimated in relation to research. Therefore, more weight should be placed on the former both in selecting scientists for the career as academic teachers and in evaluating and ranking departments for their academic activities. In the future veterinary medicine will have to cope with profound changes in the society and the veterinary profession, and the progressing European unification will enhance trends for internationalizing teaching curricula. Therefore, veterinary medicine has to reconsider the teaching subjects and methods and to lay more emphasis on flexibility, skills of problem-solving and self-learning and on training for life-long learning. At present there is an ongoing discussion on the question how to teach veterinary medicine, including veterinary parasitology. There are various options, and some of them are discussed, namely, the disciplinary and the problem-based/organ-focussed approaches. It is concluded that for teaching of veterinary parasitology and related disciplines a combined disciplinary and problem-based approach offers the best chances for fulfilling the requirements of teaching for the future. In the curriculum of undergraduate teaching of veterinary medicine at least 70-90 h should be dedicated to veterinary parasitology using a disciplinary and taxonomic approach. Additional

What is the veterinary professional identity? Preliminary findings from web-based continuing professional development in veterinary professionalism.

Professionalism and professional skills are increasingly being incorporated into veterinary curricula; however, lack of clarity in defining veterinary professionalism presents a potential challenge for directing course outcomes that are of benefit to the veterinary professional. An online continuing education course in veterinary professionalism was designed to address a deficit in postgraduate support in this area; as part of this course, delegates of varying practice backgrounds participated in online discussions reflecting on the implications of professional skills for their clinical practice. The discussions surrounding the role of the veterinary professional and reflecting on strengths and weaknesses in professional skills were analysed using narrative methodology, which provided an understanding of the defining skills and attributes of the veterinary professional, from the perspectives of those involved (i.e. how vets understood their own career identity). The veterinary surgeon was understood to be an interprofessional team member, who makes clinical decisions in the face of competing stakeholder needs and works in a complex environment comprising multiple and diverse challenges (stress, high emotions, financial issues, work-life balance). It was identified that strategies for accepting fallibility, and those necessary for establishing reasonable expectations of professional behaviour and clinical ability, are poorly developed.

To assess student awareness of the financial costs of pursuing a veterinary education, to determine student expectations for financial returns of a veterinary career, and to identify associations between student debt and factors such as future career plans or personality type. Survey. First-year veterinary students at the University of Minnesota College of Veterinary Medicine. In 2013, prior to the first day of class, all incoming first-year students received an email invitation to complete an online survey. The survey contained questions about demographics, current financial situation, current debt, expected debt at graduation, expected annual income following graduation, intent to pursue specialty training, and Myers-Briggs personality type. 72 of 102 (71%) students completed the survey; 65 respondents answered all relevant questions and provided usable data. Student responses for expected debt at graduation were comparable to national averages for veterinary college graduates; responses for expected annual income following graduation were lower than averages for University of Minnesota veterinary college graduates and national averages. However, students predicted even lower annual income if they did not attend veterinary college. Expected debt and expected annual income were not correlated with factors such as personality type or future career plans. Results indicated that first-year veterinary students were aware of the financial costs of their veterinary education and had realistic expectations for future salaries. For typical veterinary students, attending veterinary college appeared to be financially worthwhile, given lower expected earnings otherwise.

The Veterinary Historical Museum at the School of Veterinary Medicine was founded in 1973. It is the only museum of this kind in Germany at the moment this is open to the public. More than 600 exhibits give information on the history of the School of Veterinary Medicine since 1778 as well as on the development of the different veterinary working fields and the diagnosis and treatment methods during the last centuries. The academic collection contains about 2500 objects that keep the veterinary cultural possessions out of the areas: science, practices, administration and personal sphere. A certain military historical collection also belongs to the museum, the so-called "Sammlung Wens". The Institute for Veterinary History is responsible for the administration and the maintenance of the museum. Like in every other museum it was and is still tried to fulfill the basic tasks of museum work, there are: collecting, keeping, exhibiting, exploring and teaching. These working fields leave a lot of problems due to the "hermaphroditic" position of the museum as a part of the School of Veterinary Medicine on the one hand and as a public museum on the other hand. The result is that the museum has neither specialist staff nor an independent budget until today. A guided tour in the museum and the critical representation of its tasks explain a stalemate situation that should absolutely be avoided at the conception of a future museum for veterinary medicine as it is planned in Berlin.

Careers in Veterinary Medicine is a required, one-credit-hour course at the North Carolina State University College of Veterinary Medicine (NCSU-CVM), which meets once weekly during veterinary students' first semester. Lectures in this course are presented by one or more veterinarians representing diverse career areas. A voluntary, anonymous survey was distributed before the first class meeting in 2011 (PRE) and at the end of the semester (POST) to assess if students' career interests changed during the semester. The survey collected basic demographic data and students' preferences (on a Likert scale) for 17 veterinary career paths. Out of 63 students, 36 (57%) in the POST survey said that their career interests had changed during the semester, and 17 of the 26 students (65%) who gave a reason credited the careers course as one factor in reconsidering their career choice. Only 3 of the 17 career paths had statistically significant PRE/POST survey differences in Likert response frequency (equine practice, pathology, and wildlife medicine), but both informal discussions with students and responses to open-ended survey questions indicated that many students valued the introduction to unfamiliar veterinary career areas. Careers in Veterinary Medicine is a vital component of recent career-planning initiatives in the college, which will be especially important to veterinary students as they face continued changes in the profession, such as the increased debt load of the new graduate and the threat of veterinary workforce oversupply.

Automatic segmentation and classification of gestational sac based on mean sac diameter using medical ultrasound image

NASA Astrophysics Data System (ADS)

Khazendar, Shan; Farren, Jessica; Al-Assam, Hisham; Sayasneh, Ahmed; Du, Hongbo; Bourne, Tom; Jassim, Sabah A.

2014-05-01

Ultrasound is an effective multipurpose imaging modality that has been widely used for monitoring and diagnosing early pregnancy events. Technology developments coupled with wide public acceptance has made ultrasound an ideal tool for better understanding and diagnosing of early pregnancy. The first measurable signs of an early pregnancy are the geometric characteristics of the Gestational Sac (GS). Currently, the size of the GS is manually estimated from ultrasound images. The manual measurement involves multiple subjective decisions, in which dimensions are taken in three planes to establish what is known as Mean Sac Diameter (MSD). The manual measurement results in inter- and intra-observer variations, which may lead to difficulties in diagnosis. This paper proposes a fully automated diagnosis solution to accurately identify miscarriage cases in the first trimester of pregnancy based on automatic quantification of the MSD. Our study shows a strong positive correlation between the manual and the automatic MSD estimations. Our experimental results based on a dataset of 68 ultrasound images illustrate the effectiveness of the proposed scheme in identifying early miscarriage cases with classification accuracies comparable with those of domain experts using K nearest neighbor classifier on automatically estimated MSDs.

Circular dichroism spectra of uridine derivatives: ChiraSac study.

Miyahara, Tomoo; Nakatsuji, Hiroshi; Wada, Takehiko

2014-04-24

The experimental circular dichroism (CD) spectra of uridine and NH2-uridine that were different in the intensity and shape were studied in the light of the ChiraSac method. The theoretical CD spectra at several different conformations using the symmetry-adapted-cluster configuration-interaction (SAC-CI) theory largely depended on the conformational angle, but those of the anti-conformers and the Boltzmann average reproduced the experimentally obtained CD spectra of both uridine and NH2-uridine. The differences in the CD spectra between the two uridine derivatives were analyzed by using the angle θ between the electric transition dipole moment (ETDM) and the magnetic transition dipole moment (MTDM).

The study aimed to identify barriers to the implementation of nutrition consultation in veterinary practice. Differences between individual veterinarians in their problem-solving strategies in nutrition consultation were investigated. Representative online survey of 214 veterinarians (female/male) using a standardized questionnaire. Statistical analysis by correlations, t-test, analysis of variance and factor analysis as well as cluster analysis of types of veterinarians. Over 90% of vets had seen an increase in owners' questions on feeding pets. Forty-one percent estimated the percentage of patients suffering from nutrition-related diseases in their practice to be 20-30%. At the same time, 70% of vets agreed that nutrition consultation was neglected in every-day practice. Vets estimated that only 30% of owners complied with recommendations on nutrition. Over 80% of vets presumed that pet owners gave false information on feeding. For other sensitive questions, including domestic and financial situations, the percentage of presumed false information was below 60%. Approximately 50% of the vets did not feel sufficiently competent with regard to nutrition consultation. Less than 50% asked for payment of nutrition consultation. Only 18% had taken part in continuing education in animal nutrition. The cluster analysis identified five different strategies to cope with nutrition consultation, four of which were based on a low priority for nutrition in their own practice. Some vets referred nutrition problems to specialized colleagues (7.2%), others consulted with representatives of pet food companies (28.2%), another group offered free, quick tips (23.4%), and a small percentage ignored nutrition (13.4%). There was one group with a strong interest in nutrition (27.8%). It is remarkable that this group felt the least competent in small-animal nutrition. Conclusion and practical relevance: The study demonstrates that sound nutrition consultation in small-animal practice

Sac1--Vps74 structure reveals a mechanism to terminate phosphoinositide signaling in the Golgi apparatus

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cai, Yiying; Deng, Yongqiang; Horenkamp, Florian

2014-08-25

Sac1 is a phosphoinositide phosphatase of the endoplasmic reticulum and Golgi apparatus that controls organelle membrane composition principally via regulation of phosphatidylinositol 4-phosphate signaling. We present a characterization of the structure of the N-terminal portion of yeast Sac1, containing the conserved Sac1 homology domain, in complex with Vps74, a phosphatidylinositol 4-kinase effector and the orthologue of human GOLPH3. The interface involves the N-terminal subdomain of the Sac1 homology domain, within which mutations in the related Sac3/Fig4 phosphatase have been linked to Charcot–Marie–Tooth disorder CMT4J and amyotrophic lateral sclerosis. Disruption of the Sac1–Vps74 interface results in a broader distribution of phosphatidylinositolmore » 4-phosphate within the Golgi apparatus and failure to maintain residence of a medial Golgi mannosyltransferase. The analysis prompts a revision of the membrane-docking mechanism for GOLPH3 family proteins and reveals how an effector of phosphoinositide signaling serves a dual function in signal termination.« less

Committee on Veterinary Medicine at the Society for Medical Education: Skills Labs in Veterinary Medicine - a brief overview.

PubMed

Dilly, Marc; Gruber, Christian

2016-01-01

Since 2012, skills labs have been set up to teach practical skills at veterinary training facilities in the German-speaking world. In addition to didactic considerations, ethical points of view in terms of animal protection form the basis of the increasing significance of skills labs in veterinary medicine. Not least because of the quality standards in veterinary medicine training which apply across Europe, the link between veterinary medicine training facilities is particularly significant when it comes to the setting up and development of skills labs. The Committee on Veterinary Medicine is therefore not only interested in exchange and cooperation within veterinary medicine, but also sees an opportunity for mutual gain in the link with the Society for Medical Education Committee "Practical Skills".

The pre-treatment presence of at least six efferent patent vessels (EPV) from the AAA sac and/or AAA thrombus volume ratio (VR%) <40% are considered to be positive predictive factors for persistent type II endoleak (ELIIp). The aim of the present study was to evaluate the effectiveness of sac embolization during EVAR in patients with pre-operative morphological risk factors (p-MRF) for ELIIp. Patients undergoing EVAR and intra-procedural AAA sac embolization (Group A, 2012-2013) were retrospectively selected and compared with a control group of patients with the same p-MRF, who underwent EVAR without intra-procedural sac embolization (Group B, 2008-2010). The presence of ELIIp was evaluated by duplex ultrasound at 0 and 6 months, and by contrast enhanced ultrasound at 12 months. The association between AAA diameter, age, COPD, smoking, anticoagulant therapy, and AAA sac embolization with ELIIp was evaluated using multiple logistic regression. The primary endpoint was the effectiveness of the intra-procedural AAA sac embolization for ELIIp prevention. Secondary endpoints were AAA sac evolution and freedom from ELIIp and embolization related re-interventions at 6-12 months. Seventy patients were analyzed: 26 Group A and 44 Group B; the groups were homogeneous for clinical/morphological characteristics. In Group A the median number of coils positioned in AAA sac was 4.1 (IQR 1). There were no complications related to the embolization procedures. A significantly lower number of ELIIp was detected in Group A than in Group B (8/26 vs. 33/44, respectively, p < .001) at discharge, and this was confirmed at 6-12 months (7/26 vs. 30/44 respectively, p = .001, and 5/25 vs. 32/44, respectively, p < .001). On multivariate analysis, intra-procedural AAA sac embolization was the only factor independently associated with freedom from ELIIp at 6 (OR 0.196, 95% CI 0.06-0.63; p = .007) and 12 months (OR 0.098, 95% CI 0.02-0.35; p < .001). No differences in median AAA sac

Needlestick injuries in veterinary medicine.

Needlestick injuries are an inherent risk of handling needles during the course of veterinary practice. While significant effort has been expended to reduce needlestick injuries in human medicine, a relatively lax approach seems to be prevalent in veterinary medicine. It appears that needlestick injuries are very common among veterinary personnel and that serious adverse effects, while uncommon, do occur. Clients may also receive injuries in clinics during the course of animal restraint, and at home following prescription of injectable medications or fluids. Because of occupational health, personal health, and liability concerns, veterinary practices should review the measures they are taking to reduce the likelihood of needlestick injuries and develop written needlestick injury avoidance protocols.

Microscopy (skill of using a microscope) and the concepts of cytology (study of cells) and histology (study of tissues) are most often taught in professional veterinary medicine programs through the traditional method of glass slides and light microscopes. Several limiting factors in veterinary training programs are encouraging educators to explore innovative options for teaching microscopy skills and the concepts of cytology and histology. An anonymous online survey was administered through the Colorado Veterinary Medical Association to Colorado veterinarians working in private practice. It was designed to assess their current usage of microscopes for cytological and histological evaluation of specimens and their perceptions of microscope use in their veterinary education. The first part of the survey was answered by 183 veterinarians, with 104 indicating they had an onsite diagnostic lab. Analysis pertaining to the use of the microscope in practice and in veterinary programs was conducted on this subset. Most respondents felt the amount of time spent in the curriculum using a microscope was just right for basic microscope use and using the microscope for viewing and learning about normal and abnormal histological sections and clinical cytology. Participants felt more emphasis could be placed on clinical and diagnostic cytology. Study results suggest that practicing veterinarians frequently use microscopes for a wide variety of cytological diagnostics. However, only two respondents indicated they prepared samples for histological evaluation. Veterinary schools should consider these results against the backdrop of pressure to implement innovative teaching techniques to meet the changing needs of the profession.

A Survey of Attitudes of Board-Certified Veterinary Pathologists to Forensic Veterinary Pathology.

PubMed

McEwen, B J; McDonough, S P

2016-09-01

An electronic survey was conducted to determine the attitudes of veterinary pathologists toward forensic pathology and the adequacy of their training in the discipline. The survey was sent to 1933 diplomates of the American College of Veterinary Pathologists and 311 completed responses were analyzed. Of respondents, 80% report receiving at least 1 type of medicolegal case, with cases from law enforcement received most frequently. Most (74%) of the respondents indicated that their previous training did not prepare them adequately to handle forensic cases and almost half of the respondents (48%) indicated that they needed more training on serving as an expert witness. Relative risk ratios (RRR) and odds ratios (OR) were generated to determine the strength of a statistically significant association. Responses from a free-text entry question determining additional training needs could be grouped into 3 main categories: (1) veterinary forensic pathology science and procedures, (2) documentation, evidence collection and handling, and (3) knowledge of the medicolegal system. Last, a field for additional comments or suggestions regarding veterinary forensic pathology was completed by 107 respondents and many reinforced the need for training in the categories previously described. The survey highlights that a significant proportion of diplomates of the American College of Veterinary Pathologists are currently engaged in veterinary forensic pathology but feel their training has not adequately prepared them for these cases. Hopefully, the survey results will inform the college and residency training coordinators as they address the training requirements for an important emerging discipline. © The Author(s) 2016.

Ostrzenski, Adam; Krajewski, Pawel; Davis, Kern

2016-09-01

To determine whether there is any new anatomical structure present within the labia majora. A case serial study was executed on eleven consecutive fresh human female cadavers. Stratum-by-stratum dissections of the labia majora were performed. Twenty-two anatomic dissections of labia majora were completed. Eosin and Hematoxylin agents were used to stain newly discovered adipose sac's tissues of the labia majora and the cylinder-like structures, which cover condensed adipose tissues. The histology of these two structures was compared. All dissected labia majora demonstrated the presence of the anatomic existence of the adipose sac structure. Just under the dermis of the labia majora, the adipose sac was located, which was filled with lobules containing condensed fatty tissues in the form of cylinders. The histological investigation established that the well-organized fibro-connective-adipose tissues represented the adipose sac. The absence of descriptions of the adipose sac within the labia majora in traditional anatomic and gynecologic textbooks was noted. In this study group, the newly discovered adipose sac is consistently present within the anatomical structure of the labia majora. The well-organized fibro-connective-adipose tissue represents microscopic characteristic features of the adipose sac.

There is little information relating to infection control procedures in Australian veterinary practices. This review summarises the findings of international studies in the area of zoonoses and infection control, and discusses potential reasons for the apparent complacency about these issues in veterinary practice. It is the authors' opinion that legislative changes governing veterinary practice in Australia should be implemented. The curricula in veterinary schools should also emphasise infection control. These measures would significantly improve safety issues associated with the control of zoonoses in veterinary practice. © 2012 The Authors.

Rectal sac distention is induced by 20-hydroxyecdysone in the pupa of Bombyx mori.

PubMed

Suzuki, Takumi; Sakurai, Sho; Iwami, Masafumi

2009-03-01

Holometabolous insects do not excrete but store metabolic wastes during the pupal period. The waste is called meconium and is purged after adult emergence. Although the contents of meconium are well-studied, the developmental and physiological regulation of meconium accumulation is poorly understood. In Bombyx mori, meconium is accumulated in the rectal sac; thereby, the rectal sac distends at the late pupal stage. Here, we show that rectal sac distention occurs between 4 and 5 days after pupation. The distention is halted by brain-removal just after larval-pupal ecdysis but not by brain-removal 1 day after pupation. In the pupae, brain-removal just after ecdysis kept the hemolymph ecdysteroid titer low during early and mid-pupal stages. An injection of 20-hydroxyecdysone (20E) evoked the distention that was halted by brain-removal in a dose-dependent manner. Therefore, brain-removal caused the lack of ecdysteroid, and rectal sac distention did not appear in the brain-removed pupae because of the lack of ecdysteroid. We conclude that rectal sac distention is one of the developmental events regulated by 20E during the pupal period in B. mori.

2014-01-01

Although it is widely agreed that veterinary students need to be introduced to ethics, there is limited empirical research investigating the reasons why veterinary ethics is being taught. This study presents the first extensive investigation into the reasons for teaching veterinary ethics and reports data collected in semi-structured interviews with educators involved in teaching undergraduate veterinary ethics at three European schools: the University of Copenhagen, the University of Nottingham, and the Technical University of Lisbon (curricular year 2010-2011). The content of the interview transcripts were analyzed using Toulmin's argumentative model. Ten objectives in teaching veterinary ethics were identified, which can be grouped into four overarching themes: ethical awareness, ethical knowledge, ethical skills, and individual and professional qualities. These objectives include recognizing values and ethical viewpoints, identifying norms and regulations, developing skills of communication and decision making, and contributing to a professional identity. Whereas many of the objectives complement each other, there is tension between the view that ethics teaching should promote knowledge of professional rules and the view that ethics teaching should emphasize critical reasoning skills. The wide range of objectives and the possible tensions between them highlight the challenges faced by educators as they attempt to prioritize among these goals of ethics teaching within a crowded veterinary curriculum.

Veterinary and human vaccine evaluation methods

Knight-Jones, T. J. D.; Edmond, K.; Gubbins, S.; Paton, D. J.

2014-01-01

Despite the universal importance of vaccines, approaches to human and veterinary vaccine evaluation differ markedly. For human vaccines, vaccine efficacy is the proportion of vaccinated individuals protected by the vaccine against a defined outcome under ideal conditions, whereas for veterinary vaccines the term is used for a range of measures of vaccine protection. The evaluation of vaccine effectiveness, vaccine protection assessed under routine programme conditions, is largely limited to human vaccines. Challenge studies under controlled conditions and sero-conversion studies are widely used when evaluating veterinary vaccines, whereas human vaccines are generally evaluated in terms of protection against natural challenge assessed in trials or post-marketing observational studies. Although challenge studies provide a standardized platform on which to compare different vaccines, they do not capture the variation that occurs under field conditions. Field studies of vaccine effectiveness are needed to assess the performance of a vaccination programme. However, if vaccination is performed without central co-ordination, as is often the case for veterinary vaccines, evaluation will be limited. This paper reviews approaches to veterinary vaccine evaluation in comparison to evaluation methods used for human vaccines. Foot-and-mouth disease has been used to illustrate the veterinary approach. Recommendations are made for standardization of terminology and for rigorous evaluation of veterinary vaccines. PMID:24741009

Veterinary research laboratories play an essential role in the provision of veterinary services in most countries. These laboratories are the source of new knowledge, innovative ideas and improved technology for the surveillance, prevention and control of animal diseases. In addition, many laboratories provide diagnostic and other services. To ensure the optimal integration of various veterinary activities, administrators must understand the functions and constraints of research laboratories. Therefore, a brief discussion is presented of the following: organisational structures methods for developing research programmes outputs of research scientists and how these are measured the management of quality assurance funding of research. Optimal collaboration can only be attained by understanding the environment in which a research scientist functions and the motivational issues at stake.

Pet markets involve in great commercial possibilities, which boost thriving development of veterinary hospital businesses. The service tends to intensive competition and diversified channel environment. Information technology is integrated for developing the veterinary hospital cloud service platform. The platform contains not only pet medical services but veterinary hospital management and services. In the study, QR Code andcloud technology are applied to establish the veterinary hospital cloud service platform for pet search by labeling a pet's identification with QR Code. This technology can break the restriction on veterinary hospital inspection in different areas and allows veterinary hospitals receiving the medical records and information through the exclusive QR Code for more effective inspection. As an interactive platform, the veterinary hospital cloud service platform allows pet owners gaining the knowledge of pet diseases and healthcare. Moreover, pet owners can enquire and communicate with veterinarians through the platform. Also, veterinary hospitals can periodically send reminders of relevant points and introduce exclusive marketing information with the platform for promoting the service items and establishing individualized marketing. Consequently, veterinary hospitals can increase the profits by information share and create the best solution in such a competitive veterinary market with industry alliance.

There is an international shortage of veterinary clinical pathologists in the workplace. Current trainees in veterinary clinical pathology may choose to pursue careers in academe, diagnostic laboratories, government health services, biopharmaceutical companies, or private practice. Academic training programs attempt to provide trainees with an exposure to several career choices. However, due to the proprietary nature of much of the work in the biopharmaceutical industry, trainees may not be fully informed regarding the nature of work for veterinary clinical pathologists and the myriad opportunities that await employment in the biopharmaceutical industry. The goals of this report are to provide trainees in veterinary clinical pathology and other laboratory personnel with an overview of the work-life of veterinary clinical pathologists employed in the biopharmaceutical industry, and to raise the profile of this career choice for those seeking to enter the workforce. Biographical sketches, job descriptions, and motivation for 3 successful veterinary clinical pathologists employed in the biopharmaceutical industry are provided. Current and past statistics for veterinary clinical pathologists employed in the biopharmaceutical industry are reviewed. An overview of the drug development process and involvement of veterinary clinical pathologists in the areas of discovery, lead optimization, and candidate evaluation are discussed. Additional duties for veterinary clinical pathologists employed in the biopharmaceutical industry include development of biomarkers and new technologies, service as scientific resources, diagnostic support services, and laboratory management responsibilities. There are numerous opportunities available for trainees in veterinary clinical pathology to pursue employment in the biopharmaceutical industry and enjoy challenging and rewarding careers.

Solutions Network Formulation Report. Reducing Light Pollution in U.S. Coastal Regions Using the High Sensitivity Cameras on the SAC-C and Aquarius/SAC-D Satellites

NASA Technical Reports Server (NTRS)

Andrews, Jane C.; Knowlton, Kelly

2007-01-01

Light pollution has significant adverse biological effects on humans, animals, and plants and has resulted in the loss of our ability to view the stars and planets of the universe. Over half of the U.S. population resides in coastal regions where it is no longer possible to see the stars and planets in the night sky. Forty percent of the entire U.S. population is never exposed to conditions dark enough for their eyes to convert to night vision capabilities. In coastal regions, urban lights shine far out to sea where they are augmented by the output from fishing boat, cruise ship and oil platform floodlights. The proposed candidate solution suggests using HSCs (high sensitivity cameras) onboard the SAC-C and Aquarius/SAC-D satellites to quantitatively evaluate light pollution at high spatial resolution. New products modeled after pre-existing, radiance-calibrated, global nighttime lights products would be integrated into a modified Garstang model where elevation, mountain screening, Rayleigh scattering, Mie scattering by aerosols, and atmospheric extinction along light paths and curvature of the Earth would be taken into account. Because the spatial resolution of the HSCs on SAC-C and the future Aquarius/SAC-D missions is greater than that provided by the DMSP (Defense Meteorological Satellite Program) OLS (Operational Linescan System) or VIIRS (Visible/Infrared Imager/Radiometer Suite), it may be possible to obtain more precise light intensity data for analytical DSSs and the subsequent reduction in coastal light pollution.

Epilepsy is one of the most common chronic neurological diseases in veterinary practice. Magnetic resonance imaging (MRI) is regarded as an important diagnostic test to reach the diagnosis of idiopathic epilepsy. However, given that the diagnosis requires the exclusion of other differentials for seizures, the parameters for MRI examination should allow the detection of subtle lesions which may not be obvious with existing techniques. In addition, there are several differentials for idiopathic epilepsy in humans, for example some focal cortical dysplasias, which may only apparent with special sequences, imaging planes and/or particular techniques used in performing the MRI scan. As a result, there is a need to standardize MRI examination in veterinary patients with techniques that reliably diagnose subtle lesions, identify post-seizure changes, and which will allow for future identification of underlying causes of seizures not yet apparent in the veterinary literature.There is a need for a standardized veterinary epilepsy-specific MRI protocol which will facilitate more detailed examination of areas susceptible to generating and perpetuating seizures, is cost efficient, simple to perform and can be adapted for both low and high field scanners. Standardisation of imaging will improve clinical communication and uniformity of case definition between research studies. A 6-7 sequence epilepsy-specific MRI protocol for veterinary patients is proposed and further advanced MR and functional imaging is reviewed.

Chemotherapy of yolk sac tumor heterotransplanted to nude mice was studied. 1. Yolk sac tumor of the ovary taken from a 38-year -old woman was transplanted to BALB/c female nude mice. The transplantable tumor cells produce a solid tumor, designated as YST-1 tumor. The YST-1 tumor cells preserve the histological appearance of a human yolk sac tumor and produce x-fetoprotein. The tumors on passage 8 were used for experimental chemotherapy. 2. Anticancer drugs clinically known to be effective for ovarian cancer, such as Adriamycin, Carbazilquinone, 5-Fluorouracil, Cyclophosphamide, Mitomycin C, Chromomycin A3, Vinblastine and Bleomycin were administered intraperitoneally to tumor-bearing nude mice. Tumor size was measured two or three times a week during the course of experiments. Therapeutic effects were evaluated by tumor size and relative tumor size before and after experiments. Among these drugs, Vinblastine and Bleomycin combination showed the significant effect arresting the growth of YST-1 tumor.

Physiological requirements for 20-hydroxyecdysone-induced rectal sac distention in the pupa of the silkworm, Bombyx mori.

PubMed

Suzuki, Takumi; Sakurai, Sho; Iwami, Masafumi

2010-06-01

Successful insect development is achieved via appropriate fluctuation of ecdysteroid levels. When an insect's ecdysteroid level is disrupted, physiological and developmental defects occur. In the pupa of the silkworm, Bombyx mori, the rectal sac is an essential organ that operates as a repository for degraded ecdysteroids, and it can be distended by administration of 20-hydroxyecdysone (20E). Our previous study showed that rectal sac distention appears 4 days after 20E administration. Hemolymph ecdysteroid levels, however, decrease to lower level during this period. Thus, the timing of the rectal sac distention does not match with that of ecdysteroid elevation. Here, we examine how 20E induces rectal sac distention. A ligature experiment and ecdysteroid quantification showed that continuous 20E stimulation induces rectal sac distention. Thorax tissue contributed to the continuous 20E stimulation needed to induce distention. Ecdysteroid released from the thorax tissue may be converted to 20E by ecdysone 20-hydroxylase to produce continuous 20E stimulation. Thus, the ecdysone metabolic pathway plays a critical role in rectal sac distention. Copyright 2010 Elsevier Ltd. All rights reserved.

Bibliometric analysis of the American Journal of Veterinary Research to produce a list of core veterinary medicine journals

PubMed Central

Crawley-Low, Jill

2006-01-01

Objective: Bibliometric techniques were used to analyze the citation patterns of researchers publishing in the American Journal of Veterinary Research (AJVR). Methods: The more than 25,000 bibliographic references appearing in the AJVR from 2001 to 2003 were examined for material type, date of publication, and frequency of journals cited. Journal titles were ranked in decreasing order of productivity to create a core list of journals most frequently used by veterinary medical researchers. Results: The majority of items cited were journals (88.8%), followed by books (9.8%) and gray literature (2.1%). Current sources of information were favored; 65% of the journals and 77% of the books were published in 1990 or later. Dividing the cited articles into 3 even zones revealed that 24 journals produced 7,361 cited articles in the first zone. One hundred thirty-nine journals were responsible for 7,414 cited articles in zone 2, and 1,409 journals produced 7,422 cited articles in zone 3. Conclusions: A core collection of veterinary medicine journals would include 49 veterinary medicine journals from zones 1 and 2. Libraries supporting a veterinary curriculum or veterinary research should also include veterinary medical journals from Zone 3, as well as provide access to journals in non-veterinary subjects such as biochemistry, virology, orthopedics, and surgery and a selection of general science and medical journals.

This fourth article in an ongoing series of articles published in the Journal of Veterinary Medical Education on veterinary education and the veterinary profession provides information on the colleges and schools that exist in the US in 2011. This article provides a brief description of the educational programs and recent accreditation of the veterinary schools at Western University of the Health Sciences and Ross University on the Island of St. Kitts. Without taking into consideration Caribbean colleges, the number of veterinary student positions in US colleges has increased by approximately 24% in the past decade. The number of students attending veterinary colleges is unevenly distributed across the country with many of the more populous states having fewer students per 100,000 people than less populous states. The percentage of veterinarians who reside in the state of their alma mater also varies widely with alumni from some colleges remaining in the state of the college from which they graduated (e.g., Texas A&M and the University of California at Davis) and the graduates of other colleges (e.g., Cornell University and the University of Pennsylvania) being more widely distributed across the country. The location of veterinarians is also provided by state and adjusted for population and state size.

Electromigration effect on intermetallic growth and Young's modulus in SAC solder joint

NASA Astrophysics Data System (ADS)

Xu, Luhua; Pang, John H. L.; Ren, Fei; Tu, K. N.

2006-12-01

Solid-state intermetallic compound (IMC) growth behavior plays and important role in solder joint reliability of electronic packaging assemblies. The directional impact of electromigration (EM) on the growth of interfacial IMCs in Ni/SAC/Ni, Cu/SAC/Ni single BGA ball solder joint, and fine pitch ball-grid-array (FPBGA) at the anode and cathode sides is reported in this study. When the solder joint was subjected to a current density of 5,000 A/cm2 at 125°C or 150°C, IMC layer growth on the anode interface was faster than that on the cathode interface, and both were faster than isothermal aging due to the Joule heating effect. The EM affects the IMC growth rate, as well as the composition and mechanical properties. The Young’s modulus and hardness were measured by the nanoindentation continuous stiffness measurement (CSM) from planar IMC surfaces after EM exposure. Different values were observed at the anode and cathode. The energy-dispersive x-ray (EDX) line scan analysis was conducted at the interface from the cathode to anode to study the presence of species; Ni was found in the anode IMC at SAC/Cu in the Ni/SAC/Cu joint, but not detected when the current was reverse. Electron-probe microanalysis (EPMA) measurement on the Ni/SAC/Ni specimen also confirmed the polarized Ni and Cu distributions in cathode and anode IMCs, which were (Ni0.57Cu0.43)3Sn4 and (Cu0.73Ni0.27)6Sn5, respectively. Thus, the Young’s moduli of the IMC are 141 and 175 GPa, respectively.

Development and morphology of the inverted yolk sac in the guinea pig (Cavia porcellus).

Vasconcelos, Bruno Gomes; Favaron, Phelipe Oliveira; Miglino, Maria Angelica; Mess, Andrea Maria

2013-10-01

Although the guinea pig is an important animal model for human placentation, aspects of fetal nutrition are not fully understood, especially in regard to the yolk sac that is regarded to be essential for early development of the embryo. We investigated differentiation by means of histology, histochemistry, immunohistochemistry, and transmission electron microscopy. Data suggest that the guinea pig's yolk sac was not sufficiently developed to facilitate substantial fetal nutrition in early pregnancy. On Day 12, it was a flat, inverted, but avascular structure. This was followed by differentiation to form the typical, highly villous and vascularized condition of advanced gestation. Finally, the yolk sac degenerated toward term. We suggest that the guinea pig and other caviomorphs rely predominantly on hemotrophic nutrition via the placenta even in very early pregnancy. In contrast to the general pattern of mammals, histiotrophic nutrition via yolk sac routes seems to be most essential during mid-gestation. Copyright © 2013 Elsevier Inc. All rights reserved.

Modeling the Rate-Dependent Durability of Reduced-Ag SAC Interconnects for Area Array Packages Under Torsion Loads

2013-08-01

Solder durability models frequently focus on the applied strain range; however, the rate of applied loading, or strain rate, is also important. In this study, an approach to incorporate strain rate dependency into durability estimation for solder interconnects is examined. Failure data were collected for SAC105 solder ball grid arrays assembled with SAC305 solder that were subjected to displacement-controlled torsion loads. Strain-rate-dependent (Johnson-Cook model) and strain-rate-independent elastic-plastic properties were used to model the solders in finite-element simulation. Test data were then used to extract damage model constants for the reduced-Ag SAC solder. A generalized Coffin-Manson damage model was used to estimate the durability. The mechanical fatigue durability curve for reduced-silver SAC solder was generated and compared with durability curves for SAC305 and Sn-Pb from the literature.

The European system of veterinary specialization.

PubMed

Romagnoli, Stefano

2010-01-01

Veterinary specialist diplomas were available in many European countries during the second half of the 20th century. However, such an early recognition of the importance of veterinary specialization actually delayed the concept of the European veterinary specialist in Europe, compared with the United States, where the first specialist colleges were established in the 1960s, because it was felt that the national system was functioning properly and there was therefore no need for a new structure in the European countries. The European Board of Veterinary Specialisation (EBVS) was established in 1996, and currently there are 23 specialist colleges with more than 2,600 veterinarians officially listed in the EBVS register as European specialists. The Advisory Committee on Veterinary Training (ACVT) approved the establishment of EBVS but never implemented a supervising body (with ACVT representation). Such a body, the European Coordinating Committee on Veterinary Training, was later implemented by the profession itself, although it still lacked a political component. Each college depends on the EBVS, which has the function to define standards and criteria for monitoring the quality of college diplomates. To become a European Diplomate, veterinarians must have gone through an intensive period of training supervised by a diplomate, after which candidates must pass an examination. Although the term European veterinary specialist still does not have any legal recognition, national specialist qualifications are being phased out in many countries because of the inherent higher quality of EBVS specialist qualifications.

Microstructures and mechanical property of Sn-3.0Ag-0.5Cu (SAC305) and epoxy Sn-3.0Ag-0.5Cu (epoxy SAC) solder joints were investigated with various surface finishes; organic solderability preservative (OSP), electroless nickel immersion gold (ENIG) and electroless nickel electroless palladium immersion gold (ENEPIG). Bending property of solder joints was evaluated by 3-point bend test method. Microstructure and chemical composition of solder joints was characterized by scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDX), respectively. Epoxy did not effect on intermetallic compound (IMC) morphology. Scalloped shaped Cu6Sn5 IMC was observed at OSP surface finish. Chunky-like shaped and needle-like shaped (Ni,Cu)6Sn5 IMC were observed at the solder/ENIG joint and solder/ENEPIG joint, respectively. The bending cycles of SAC305/OSP joint, SAC305/ENIG joints and SAC305/ENEPIG joints were 720, 440 and 481 cycle numbers. The bending cycles of epoxy SAC and three types surface finished solder joints were over 1000 bending cycles. Under OSP surface finish, bending cycles of epoxy SAC solder was approximately 1.5 times higher than those of SAC305 solder joint. Bending cycles of epoxy SAC solder was over twice times higher than those of SAC305 solder with ENIG and ENEPIG surface finishes. The bending property of epoxy solder joint was enhanced due to epoxy fillet held the solder joint.

To identify survival and morbidity information after surgery for metastases from apocrine gland anal sac adenocarcinomas (AGACA). Retrospective study. Five dogs with AGACA. Medical records of dogs that had surgery for treatment of metastatic AGACA between 1993 and 2003 were reviewed. Criteria for inclusion required that dogs had lymphadenectomy, with or without further debulking, as part of their treatment for metastatic AGACA and that the tissue was histologically confirmed as consistent with the primary AGACA. Signalment, history, physical examination findings, clinicopathologic data, imaging findings, surgical complications, number of surgeries, survival times, and cause of death were recorded. All dogs had a complete blood count, serum biochemical profile, serum electrolytes, 3-projection thoracic radiographs, abdominal radiographs and/or abdominal ultrasonography, and histologic confirmation of metastatic AGACA invading the regional lymph nodes and caudal abdomen. No surgical complications occurred. Three dogs were euthanatized; median survival, 20.6 months. One dog was alive for 19 months postoperatively. One dog had 5 sequential surgical procedures: 1 iliac lymphadenectomy and 4 debulking procedures of metastatic neoplastic tissue around and dorsal to the iliac vessels extending into the pelvic cavity, and was alive 54 months after initial surgery. Dogs with anal sac adenocarcinoma metastases to the iliac lymph nodes can experience long-term survival after surgical excision of the metastatic lesion. Lymphadenectomy may afford long-term survival to patients with metastatic anal sac adenocarcinoma.

2015-01-01

We report a case of a 44-year-old man who presented with a left medial canthal mass and epiphora. Imaging was suggestive of a mass continuous with the nasolacrimal sac. Subsequent surgical exploration revealed a mass adherent to bone with invasion of the lacrimal system. Histological examination revealed a squamous/transitional cell papilloma overlying a low-grade mucoepidermoid carcinoma (MEC). Complete surgical resection was completed and pathology confirmed the diagnosis. This is the first case in which a MEC has been reported concurrently with an overlying papilloma, providing support for the hypothesis that MECs arise from papillomas in the lacrimal sac. Additionally, the tissue stained positive for p63, which is congruent with MEC immunoreactivity in the salivary gland. The description of these unique histopathological findings may assist in definitive diagnosis and improve our understanding of the pathophysiology underlying lacrimal sac MEC tumors.

Job dynamics of veterinary professionals in an academic research institution. I. Retention and turnover of veterinary technicians.

Huerkamp, Michael J

2006-09-01

The turnover of veterinary technicians within an animal resources program averaged 33% annually over 18 y, peaking at 67% in 1998 to 1999. Insufficient retention of veterinary technicians led to diversion of veterinarian effort to technical tasks and to increased allocation of administrative resources for supervising and managing an expanding team of veterinary technicians. To identify factors and trends related to poor retention, address any causes, and reduce turnover, a retrospective analysis of employment records was done. The retention of veterinary technicians was significantly greater for the 9 technicians hired from veterinary private practice rather than for any of 3 other general sources: promotions from the animal care staff, transfers from other research institutions, and miscellaneous sources. Veterinary technician turnover was reduced from a mean of 60% over 1995 to 1999 to an average of 26% during 2000 to 2004. Higher retention was associated with management practices that included renewed concentration on recruiting and interviewing strategies and emphasis on training and career development including merit raises for technician certification through the American Association for Laboratory Animal Science. Higher retention yielded correspondingly greater experience on the job as the mean tenure increased from 1.1 y in 2000 to 2.8 y in 2004. The most valued attributes related to employment by veterinary technicians as determined by survey were to do meaningful work, earn a good living, and have a committed team of coworkers.

To explore the prevalence and molecular characteristics of methicillin-resistant Staphylococcus aureus (MRSA) in veterinary medical practices, MRSA carriage was tested among 96 veterinarians (Vets), 70 veterinary technicians (VTs) and 292 dogs with which they had contact at 71 private veterinary clinics (VCs) in Hokkaido, Japan. MRSA isolates were obtained from 22 Vets [22.9%] and 7 VTs [10%]. The prevalence of MRSA among Vets was as high as that found in an academic veterinary hospital in our previous study. In contrast, only two blood donor dogs and one dog with liver disease (1.0%, 3/292) yielded MRSA. All MRSA-positive dogs were reared or treated in different VCs, in each of which at least one veterinary staff member carrying MRSA worked. Sequence types (ST) identified by multilocus sequence typing, spa types, and SCCmec types for canine MRSA isolates (ST5-spa t002-SCCmec II [from two dogs] or ST30-spa t021-SCCmec IV [from a dog]) were concordant with those from veterinary staff members in the same clinics as the MRSA-positive dogs, with which they had potentially had contact. Most MRSA isolates from veterinary staff were the same genotype (SCCmec type II and spa type t002) as a major hospital-acquired MRSA clone in Japan. The remaining MRSA was the same genotypes as domestic and foreign community-associated MRSA. Measures against MRSA infection should be provided in private VCs. © 2014 The Societies and Wiley Publishing Asia Pty Ltd.

Recent reports project a deficiency of veterinary pathologists, indicating a need to train highly qualified veterinary pathologists, particularly in academic veterinary medicine. The need to provide high-quality research training for veterinary pathologists has been recognized by the veterinary pathology training program of the Ohio State University (OSU) since its inception. The OSU program incorporates elements of both residency training and graduate education into a unified program. This review illustrates the components and structure of the training program and reflects on future challenges in training veterinary pathologists. Key elements of the OSU program include an experienced faculty, dedicated staff, and high-quality students who have a sense of common mission. The program is supported through cultural and infrastructure support. Financial compensation, limited research funding, and attractive work environments, including work-life balance, will undoubtedly continue to be forces in the marketplace for veterinary pathologists. To remain competitive and to expand the ability to train veterinary pathologists with research skills, programs must support strong faculty members, provide appropriate infrastructure support, and seek active partnerships with private industry to expand program opportunities. Shortages of trained faculty may be partially resolved by regional cooperation to share faculty expertise or through the use of communications technology to bridge distances between programs. To foster continued interest in academic careers, training programs will need to continue to evolve and respond to trainees' needs while maintaining strong allegiances to high-quality pathology training.

This article describes the ECVP/ESVP Summer School in Veterinary Pathology, a new annual two-week European training facility established by the European College of Veterinary Pathologists (ECVP) in collaboration with the European Society of Veterinary Pathology (ESVP). The aim of the Summer Schools is to provide Europe-wide, harmonized, top-standard theoretical and practical post-graduate training for veterinarians specializing in veterinary pathology. In particular, it aims to support trainees in veterinary pathology in their individual preparation for the ECVP certifying examination. Ultimately, it aims to provide young pathologists with the skills and knowledge necessary to participate in international, high-quality research and the tools for applying international standards to their own research and for independent study for the ECVP certifying examination, even if they do not work in comparable academic environments and do not have the same level of local support and training. The ECVP/ESVP Summer Schools take place in European countries, with local organization from a university department of veterinary pathology. Each event comprises modules provided by internationally recognized specialists in their specific fields of expertise on different organ systems, diseases of specific species, specific techniques, and specific topics relevant to pathology, forming a cycle of four events to cover all major topics. Every two years a mock exam is organized as a tool to monitor individual progress in preparing for the ECVP certifying examination.

In pursuit of effective veterinary service delivery, the objectives of this study were threefold: (i) reduce the shortage of technical personnel in veterinary universities (VUs) and animal husbandry departments (AHDs), (ii) identify collaborative areas between VUs and AHDs, and (iii) build the capacity of the veterinary and animal husbandry sector. Primary data were collected from all the 16 veterinary colleges and AHDs in five south Indian states on: (i) student intake and the out-turn of veterinary graduates, (ii) technical personnel--existing and required at various levels, (iii) specific areas of collaboration where VUs and AHDs need each other and can extend support to each other, and (iv) areas in which university faculty and field veterinarians would benefit from further training. Two focus group discussions were held with top administrators of VUs and AHDs to collect qualitative data. The results revealed that there are not enough veterinary graduates to meet the needs of the system and that there is a shortage of faculty, field veterinarians and para-veterinarians. Both focus groups identified areas for collaboration and capacity building to improve veterinary service delivery. The results conclusively demonstrated that India's veterinary service delivery is constrained, not due to a lack of organisations or programmes, but due to the inability of the organisations to collaborate with each other. To improve the effectiveness of veterinary service delivery it will be necessary to: admit more graduate students, support the establishment of new colleges; recruit faculty, field veterinarians and para-veterinarians; remandate the Directorates of Extension at VUs to develop linkages with AHDs; allocate funds ('special central grants') for infrastructure development to all AHDs and veterinary colleges; establish one model veterinary college that follows international standards on veterinary education and create four regional academic staff training colleges

Veterinary School Applicants: Financial Literacy and Behaviors.

Each year the Association of American Veterinary Medical Colleges (AAVMC) conducts a survey after the close of the Veterinary Medical College Application Service (VMCAS) application. The survey provides a glimpse into applicant behavior surrounding the veterinary school application process. Additional survey questions probe into applicant financial behaviors, use of financial products and services, and pet ownership. This article examines the 2013 survey data from applicants who successfully completed the application, with a focus on applicant financial literacy and behaviors. Data from the study revealed a disconnect between applicants' perception of their ability to deal with day-to-day finances and their actual financial behaviors, particularly for first-generation college student applicants and applicants who are racially/ethnically underrepresented in veterinary medicine (URVM). Many applicants were not able to accurately report the average veterinary school graduate's student debt level, which suggests the potential need for better education about the costs associated with attending veterinary school.

Air sacs are thought to be the bellows for insect respiration. However, their exact mechanism of action as a bellows remains unclear. A direct way to investigate this problem is in vivo observation of the changes in their three-dimensional structures. Therefore, four-dimensional X-ray phase contrast microtomography is employed to solve this puzzle. Quantitative analysis of three-dimensional image series reveals that the compression of the air sac during respiration in bell crickets exhibits obvious anisotropic characteristics both longitudinally and transversely. Volumetric changes of the tracheal trunks in the prothorax further strengthen the evidence of this finding. As a result, we conclude that the shrinkage and expansion of the insect air sac is anisotropic, contrary to the hypothesis of isotropy, thereby providing new knowledge for further research on the insect respiratory system.

sAC as a model for understanding the impact of endosymbiosis on cell signaling.

PubMed

Blackstone, Neil W

2014-12-01

As signaling pathways evolve, selection for new functions guides the co-option of existing material. Major transitions in the history of life, including the evolution of eukaryotes and multicellularity, exemplify this process. These transitions provided both strong selection and a plenitude of available material for the evolution of signaling pathways. Mechanisms that evolved to mediate conflict during the evolution of eukaryotes may subsequently have been co-opted during the many independent derivations of multicellularity. The soluble adenylyl cyclase (sAC) signaling pathway illustrates this hypothesis. Class III adenylyl cyclases, which include sAC, are found in bacteria, including the α-proteobacteria. These adenylyl cyclases are the only ones present in eukaryotes but appear to be absent in archaeans. This pattern suggests that the mitochondrial endosymbiosis brought sAC signaling to eukaryotes as part of an intact module. After transfer to the proto-nuclear genome, this module was then co-opted into numerous new functions. In the evolution of eukaryotes, sAC signaling may have mediated conflicts by maintaining metabolic homeostasis. In the evolution of multicellularity, in different lineages sAC may have been co-opted into parallel tasks originally related to conflict mediation. Elucidating the history of the sAC pathway may be relatively straightforward because it is ubiquitous and linked to near universal metabolic by-products (CO₂/HCO(3)(-)). Other signaling pathways (e.g., those involving STAT and VEGF) present a greater challenge but may suggest a complementary pattern. The impact of the mitochondrial endosymbiosis on cell signaling may thus have been profound.

Veterinary Forensic Pathology: The Search for Truth.

PubMed

McDonough, S P; McEwen, B J

2016-09-01

Veterinary forensic pathology is emerging as a distinct discipline, and this special issue is a major step forward in establishing the scientific basis of the discipline. A forensic necropsy uses the same skill set needed for investigations of natural disease, but the analytical framework and purpose of forensic pathology differ significantly. The requirement of legal credibility and all that it entails distinguishes the forensic from routine diagnostic cases. Despite the extraordinary depth and breadth of knowledge afforded by their training, almost 75% of veterinary pathologists report that their training has not adequately prepared them to handle forensic cases. Many veterinary pathologists, however, are interested and willing to develop expertise in the discipline. Lessons learned from tragic examples of wrongful convictions in medical forensic pathology indicate that a solid foundation for the evolving discipline of veterinary forensic pathology requires a commitment to education, training, and certification. The overarching theme of this issue is that the forensic necropsy is just one aspect in the investigation of a case of suspected animal abuse or neglect. As veterinary pathologists, we must be aware of the roles filled by other veterinary forensic experts involved in these cases and how our findings are an integral part of an investigation. We hope that the outcome of this special issue of the journal is that veterinary pathologists begin to familiarize themselves with not only forensic pathology but also all aspects of veterinary forensic science. © The Author(s) 2016.

Considerable evidence suggests that veterinary surgeons' mental health is often poorer than comparable populations and that the incidence of suicide is higher among veterinary surgeons than the general public. Veterinary students also appear to suffer from high levels of anxiety and stress, and may possess inadequate coping strategies when faced with adversity. Veterinary students may find it difficult to access central university support systems due to their heavy workload and geographical isolation on some veterinary campuses. A previous study of University of Edinburgh fourth-year veterinary students found that support services located several miles from the main veterinary campus was a barrier to students accessing counselling services. Consequently, a pilot project was initiated, which provided a counselling service at the University of Edinburgh's rural Easter Bush veterinary campus one afternoon a week during 2010. As part of the evaluation of this service, web-based questionnaires were delivered via e-mail to all veterinary staff and students towards the end of the 12-month pilot period to evaluate perceptions of barriers to student counselling and to investigate student-valued support services. Questionnaire responses were received from 35 per cent of veterinary students and 52 per cent of staff. Stigmatisation of being unable to cope was a potent inhibitor of seeking support within the veterinary environment, but counselling was perceived as valuable by the majority of staff and students. Provision of an on-site counselling service was considered important for increasing ease of access; however, students viewed friends and family as their most important support mechanism. Workload was cited as the main cause of veterinary student stress. The majority of staff and student respondents perceived veterinary students as having an increased need for counselling support compared with other students.

Good veterinary governance: definition, measurement and challenges.

Good veterinary governance assumes the provision of veterinary services that are sustainably financed, universally available, and provided efficiently without waste or duplication, in a manner that is transparent and free of fraud or corruption. Good veterinary governance is a necessary condition for sustainable economic development insomuch as it promotes the effective delivery of services and improves the overall performance of animal health systems. This article defines governance in Veterinary Services and proposes a framework for its measurement. It also discusses the role of Veterinary Services and analyses the governance dimensions of the performance-assessment tools developed by the World Organisation for Animal Health (OIE). These tools (OIE PVS Tool and PVS Gap Analysis) track the performance of Veterinary Services across countries (a harmonised tool) and over time (the PVS Pathway). The article shows the usefulness of the OIE PVS Tool for measuring governance, but also points to two shortcomings, namely (i) the lack of clear outcome indicators, which is an impediment to a comprehensive assessment of the performance of Veterinary Services, and (ii) the lack of specific measures for assessing the extent of corruption within Veterinary Services and the extent to which demand for better governance is being strengthened within the animal health system. A discussion follows on the drivers of corruption and instruments for perception-based assessments of country governance and corruption. Similarly, the article introduces the concept of social accountability, which is an approach to enhancing government transparency and accountability, and shows how supply-side and demand-side mechanisms complement each other in improving the governance of service delivery. It further elaborates on two instruments--citizen report card surveys and grievance redress mechanisms--because of their wider relevance and their possible applications in many settings, including Veterinary

Veterinary medicines in the environment.

PubMed

Boxall, A B A; Fogg, L A; Blackwell, P A; Kay, P; Pemberton, E J; Croxford, A

The impact of veterinary medicines on the environment will depend on a number of factors including physicochemical properties, amount used and method of administration, treatment type and dose, animal husbandry practices, manure storage and handling practices, metabolism within the animal, and degradation rates in manure and slurry. Once released to the environment, other factors such as soil type, climate, and ecotoxicity also determine the environmental impact of the compound. The importance of individual routes into the environment for different types of veterinary medicines varies according to the type of treatment and livestock category. Treatments used in aquaculture have a high potential to reach the aquatic environment. The main routes of entry to the terrestrial environment are from the use of veterinary medicines in intensively reared livestock, via the application of slurry and manure to land, and by the use of veterinary medicines in pasture-reared animals where pharmaceutical residues are excreted directly into the environment. Veterinary medicines applied to land via spreading of slurry may also enter the aquatic environment indirectly via surface runoff or leaching to groundwater. It is likely that topical treatments have greater potential to be released to the environment than treatments administered orally or by injection. Inputs from the manufacturing process, companion animal treatments, and disposal are likely to be minimal in comparison. Monitoring studies demonstrate that veterinary medicines do enter the environment, with sheep dip chemicals, antibiotics, sealice treatments, and anthelmintics being measured in soils, groundwater, surface waters, sediment, or biota. Maximum concentrations vary across chemical classes, with very high concentrations being reported for the sheep dip chemicals. The degree to which veterinary medicines may adsorb to particulates varies widely. Partition coefficients (K(d)) range from low (0.61 L kg(-1)) to high

To determine the role of veterinary team effectiveness regarding job satisfaction and burnout in companion animal veterinary practice. Cross-sectional observational study. 48 companion animal veterinary health-care teams. 274 team members participated in an online survey. Overall job satisfaction was evaluated with a 1-item measure, and the 3 dimensions of burnout (exhaustion, cynicism, and professional efficacy) were measured with the Maslach Burnout Inventory-General Survey. Team effectiveness was assessed with a survey developed for this study. Demographic and team effectiveness factors (coordinated team environment, toxic team environment, team engagement, and individual engagement) associated with job satisfaction and burnout were evaluated. Overall mean job satisfaction score was 5.46 of 7 (median, 6.00); veterinary technicians and kennel attendants had the lowest scores. According to the Maslach survey results, 22.4% of participants were in the high-risk category for exhaustion, 23.2% were in the high-risk category for cynicism, and 9.3% were in the high-risk category for professional efficacy. A coordinated team environment was associated with increased professional efficacy and decreased cynicism. A toxic team environment was negatively associated with job satisfaction and positively associated with exhaustion and cynicism. Individual engagement was positively associated with job satisfaction and professional efficacy and negatively associated with exhaustion and cynicism. Results suggested the effectiveness of a veterinary team can significantly influence individual team members' job satisfaction and burnout. Practices should pay specific attention to the effectiveness with which their veterinary team operates.

Guinea pig related rodents possess numerous derived placental characters. We attempt to identify diversity within the visceral yolk sac and its association with the chorioallantoic placenta in three species of caviids, two of them possessing a capsule formed by the decidua that covers the chorioallantoic placenta. The results verify that in early pregnancy all three species have an inverted yolk sac placenta. In advanced pregnancy the species differ: Galea spixii, as representative without a capsule, bear a yolk sac in apposition to the chorioallantoic placenta with signs of exchange activity until term. Galea is similar to other caviomorphs in this respect. In Dasyprocta leporina and Cuniculus paca, the representatives possessing a capsule, the yolk sac endoderm lacks signs of substance exchange. Evidently, the presence of a capsule prevents such an interaction. The variations established here must be considered if animal models for human placentation are required which have restricted access to the chorioallantoic placenta from the outside.

Factors Associated with Veterinary Clinical Faculty Attrition.

PubMed

Furr, Martin

Faculty attrition and recruitment for veterinary clinical faculty positions have been reported as significant problems in veterinary medical education. To investigate the factors that may be important in veterinary clinical faculty retention, the perceptions and views of veterinary clinical academic faculty were determined using a web-distributed electronic survey. Responses were dichotomized by whether the respondent had or had not left an academic position and were analyzed for their association with faculty attrition. A total of 1,226 responses were recorded, and results demonstrated that factors other than compensation were associated with veterinary clinical faculty attrition, including departmental culture, work-life balance, and recognition and support of clinical medicine by the administration. Forty-four percent of respondents who had held a faculty appointment reported leaving academia either voluntarily or for non-voluntary reasons such as failure to achieve tenure, retirement, or having their position closed. Attention to correcting deficiencies in workplace culture and professional rewards could be a beneficial means by which to decrease the faculty attrition rates currently observed in clinical academic veterinary medicine.

FORENSIC RADIOLOGY AND IMAGING FOR VETERINARY RADIOLOGISTS.

PubMed

Watson, Elizabeth; Heng, Hock Gan

2017-05-01

Imaging studies are often of evidentiary value in medicolegal investigations involving animals and the role of the veterinary radiologist is to interpret those images for courts as an expert or opinion witness. With progressing interest in prosecuting animal crimes and strengthening of penalties for crimes against animals, the participation of veterinary radiologists in medicolegal investigations is expected to increase. Veterinary radiologists who are aware of radiographic and imaging signs that result in animal suffering, abuse, or neglect; knowledgeable in ways radiology and imaging may support cause of death determinations; conversant in postmortem imaging; comfortable discussing mechanisms and timing of blunt or sharp force and projectile trauma in imaging; and prepared to identify mimics of abuse can assist court participants in understanding imaging evidence. The goal of this commentary review is to familiarize veterinary radiologists with the forensic radiology and imaging literature and with the advantages and disadvantages of various imaging modalities utilized in forensic investigations. Another goal is to provide background information for future research studies in veterinary forensic radiology and imaging. © 2017 American College of Veterinary Radiology.

Penguin lungs and air sacs: implications for baroprotection, oxygen stores and buoyancy.

Ponganis, P J; St Leger, J; Scadeng, M

2015-03-01

The anatomy and volume of the penguin respiratory system contribute significantly to pulmonary baroprotection, the body O2 store, buoyancy and hence the overall diving physiology of penguins. Therefore, three-dimensional reconstructions from computerized tomographic (CT) scans of live penguins were utilized to measure lung volumes, air sac volumes, tracheobronchial volumes and total body volumes at different inflation pressures in three species with different dive capacities [Adélie (Pygoscelis adeliae), king (Aptenodytes patagonicus) and emperor (A. forsteri) penguins]. Lung volumes scaled to body mass according to published avian allometrics. Air sac volumes at 30 cm H2O (2.94 kPa) inflation pressure, the assumed maximum volume possible prior to deep dives, were two to three times allometric air sac predictions and also two to three times previously determined end-of-dive total air volumes. Although it is unknown whether penguins inhale to such high volumes prior to dives, these values were supported by (a) body density/buoyancy calculations, (b) prior air volume measurements in free-diving ducks and (c) previous suggestions that penguins may exhale air prior to the final portions of deep dives. Based upon air capillary volumes, parabronchial volumes and tracheobronchial volumes estimated from the measured lung/airway volumes and the only available morphometry study of a penguin lung, the presumed maximum air sac volumes resulted in air sac volume to air capillary/parabronchial/tracheobronchial volume ratios that were not large enough to prevent barotrauma to the non-collapsing, rigid air capillaries during the deepest dives of all three species, and during many routine dives of king and emperor penguins. We conclude that volume reduction of airways and lung air spaces, via compression, constriction or blood engorgement, must occur to provide pulmonary baroprotection at depth. It is also possible that relative air capillary and parabronchial volumes are

Laparoscopic repair of hernia in children: Comparison between ligation and nonligation of sac.

PubMed

Pant, Nitin; Aggarwal, Satish Kumar; Ratan, Simmi K

2014-04-01

The essence of the current techniques of laparoscopic hernia repair in children is suture ligation of the neck of the hernia sac at the deep ring with or without its transection. Some studies show that during open hernia repair, after transection at the neck it can be left unsutured without any consequence. This study was aimed to see if the same holds true for laparoscopic hernia repair. Sixty patients (52 boys and eight girls, 12-144 months) with indirect inguinal hernia were randomized for laparoscopic repair either by transection of the sac alone (Group I) or transection plus suture ligation of sac at the neck (Group II). Outcome was assessed in terms of time taken for surgery, recurrence, and other complications. Thirty-eight hernia units in 28 patients were repaired by transection alone (Group I) and 34 hernia units in 29 patients were repaired by transection and suture ligation (Group II). Three patients were found to have no hernia on laparoscopy. Recurrence rate and other complications were not significantly different in the two groups. All recurrences occurred in hernias with ring size more than 10 mm. Laparoscopic repair of hernia by circumferential incision of the peritoneum at the deep ring is as effective as incision plus ligation of the sac.

Rural veterinary services in Western Australia: Part B. Rural practice.

To determine the current status of rural veterinary services in Western Australia. A questionnaire was sent to all eligible rural practitioners registered in 2006 and the replies were transferred to Microsoft Excel for analysis. Of the rural practitioners invited to participate in the survey replies were received from 67%. There were equal numbers of females and males. Their mean age was 44 years. Ninety per cent of respondents considered knowledge gained as an undergraduate was sufficient to equip them for practice, but only 60% considered their practical skills adequate. Thirteen per cent of those in rural practices in 2005 had left by 2006. Eighty-nine per cent of respondents were in mixed practice, the balance in specific species practice, such as equine, large animal and production animal consultancy. The majority of rural practitioners relied on servicing companion animals for their viability; 7% earned their income from servicing production animals only. Seventy per cent utilised merchandising and the sale of pet foods to supplement the income received from the traditional veterinary services and 34% found it necessary to earn an independent income. A quarter considered that rural practice did not have a future. The majority of rural practitioners in Western Australia depend on companion animals, not production animals, to remain viable, with very few operating production animal services. Poor remuneration is a major reason why veterinarians leave rural practice, and many find it necessary to supplement their income or develop an independent income.

This study was initiated to determine the recovery of Escherichia coli and selected veterinary and zoonotic pathogens from the environments of 101 community veterinary hospitals. The proportion of hospitals with positive environmental swabs were: E. coli--92%, Clostridium difficile--58%, methicillin-resistant Staphylococcus aureus (MRSA)--9%, CMY-2 producing E. coli--9%, methicillin-resistant Staphylococcus pseudintermedius--7%, and Salmonella--2%. Vancomycin-resistant Enterococcus spp., canine parvovirus, and feline calicivirus were not isolated. Prevalence of antimicrobial resistance in E. coli isolates was low. Important potential veterinary and human pathogens were recovered including Canadian epidemic strains MRSA-2 and MRSA-5, and C. difficile ribotype 027. There is an environmental reservoir of pathogens in veterinary hospitals; therefore, additional studies are required to characterize risk factors associated with HAI in companion animals, including the role of the environment.

Physical ergonomics in veterinary dentistry.

DeForge, Donald H

2002-12-01

Ergonomics is the application of a body of knowledge addressing the interactions between man and the total working environment, such as atmosphere, heat, light and sound, as well as all tools and equipment of the workplace. Work related musculoskeletal injuries, caused by poor posture, have been discussed in human dentistry for several years. Veterinary dentistry, as a relatively new specialty within veterinary medicine, should address the ergonomics of poor posture without further delay to prevent work-related injuries. The generalist, as well as the specialist and their technicians, are subject to various neck and back disorders if proper ergonomic recommendations are not followed. This review article highlights basic ergonomic design principles for illumination and posture in veterinary dentistry.

To evaluate the effects of type II endoleaks and sac pressurization on stent-graft displacement following endovascular aneurysm repair (EVAR). Experimental silicone infrarenal aneurysm (6-cm) models were "treated" with a Talent stent-graft deployed with 20-mm proximal and distal landing zones. Inflow and outflow vessels were created as part of the silicone model to control flow into the aneurysm sac. All aneurysm models were uniform, with a diameter neck of 31 mm, a neck length of 20 mm, and iliac artery diameters of 16 mm. The aortic model was secured in a water bath to a pulsatile pump under physiological conditions; the output phase ratio (%systole/%diastole) was set at 65/35 with a pump rate of 80 beats per minute. Commercially available bifurcated stent-grafts were then displaced in vitro utilizing a linear motion apparatus attached to a force gauge. The mean arterial pressure (MAP) and pulse pressure (PP) at the aortic inflow were 60.1 ± 3.1 and 38.3 ± 7.8 mmHg, respectively. Peak force to cause initial stent-graft migration with and without a type II endoleak was recorded and compared. In aneurysm sacs with no endoleak, the MAP and sac PP were 32 ± 6.4 and 6 ± 1.3 mmHg, respectively (p<0.01). In aneurysm sacs with a type II endoleak, the MAP and sac PP were 54.1 ± 9.7 and 16.1 ± 4.1 mmHg, respectively (p<0.02). Peak force to initiate migration was 16.0 ± 1.41 N (range 15-18) with no endoleak vs. 23.2 ± 2.2 N (range 20-25) in those with a type IIa endoleak and 23.5 ± 2.5 N (range 20-26) in those with a type IIb endoleak (p<0.001). Type II endoleaks are associated with a significantly increased sac pressure. Increased sac pressurization from type II endoleaks results in a significantly greater force to displace a stent-graft longitudinally. Type II endoleaks may therefore inhibit migration and offer a benefit following EVAR; however, clinical correlation of these results is required.

Ethics teaching in European veterinary schools: a qualitative case study.

Magalhães-Sant'Ana, M

2014-12-13

Veterinary ethics is recognised as a relevant topic in the undergraduate veterinary curriculum. However, there appears to be no widely agreed view on which contents are best suited for veterinary ethics teaching and there is limited information on the teaching approaches adopted by veterinary schools. This paper provides an inside perspective on the diversity of veterinary ethics teaching topics, based on an in-depth analysis of three European veterinary schools: Copenhagen, Lisbon and Nottingham. The case study approach integrated information from the analysis of syllabi contents and interviews with educators (curricular year 2010-2011). These results show that the curriculum of veterinary ethics is multidimensional and can combine a wide range of scientific, regulatory, professional and philosophical subjects, some of which may not be explicitly set out in the course descriptors. A conceptual model for veterinary ethics teaching is proposed comprising prominent topics included within four overarching concepts: animal welfare science, laws/regulations, professionalism, and theories/concepts. It is intended that this work should inform future curriculum development of veterinary ethics in European schools and assist ethical deliberation in veterinary practice.

Veterinary Compounding: Regulation, Challenges, and Resources

PubMed Central

Davidson, Gigi

2017-01-01

The spectrum of therapeutic need in veterinary medicine is large, and the availability of approved drug products for all veterinary species and indications is relatively small. For this reason, extemporaneous preparation, or compounding, of drugs is commonly employed to provide veterinary medical therapies. The scope of veterinary compounding is broad and focused primarily on meeting the therapeutic needs of companion animals and not food-producing animals in order to avoid human exposure to drug residues. As beneficial as compounded medical therapies may be to animal patients, these therapies are not without risks, and serious adverse events may occur from poor quality compounds or excipients that are uniquely toxic when administered to a given species. Other challenges in extemporaneous compounding for animals include significant regulatory variation across the global veterinary community, a relative lack of validated compounding formulas for use in animals, and poor adherence by compounders to established compounding standards. The information presented in this article is intended to provide an overview of the current landscape of compounding for animals; a discussion on associated benefits, risks, and challenges; and resources to aid compounders in preparing animal compounds of the highest possible quality.

We investigated the effects of granulation on organic acid metabolism and its relation to mineral elements in 'Guanximiyou' pummelo (Citrus grandis) juice sacs. Granulated juice sacs had decreased concentrations of citrate and isocitrate, thus lowering juice sac acidity. By contrast, malate concentration was higher in granulated juice sacs than in normal ones. The reduction in citrate concentration might be caused by increased degradation, as indicated by enhanced aconitase activity, whilst the increase in malate concentration might be caused by increased biosynthesis, as indicated by enhanced phosphoenolpyruvate carboxylase (PEPC). Real time quantitative reverse transcription PCR (qRT-PCR) analysis showed that the activities of most acid-metabolizing enzymes were regulated at the transcriptional level, whilst post-translational modifications might influence the PEPC activity. Granulation led to increased accumulation of mineral elements (especially phosphorus, magnesium, sulphur, zinc and copper) in juice sacs, which might be involved in the incidence of granulation in pummelo fruits.

To assess whether Boiler Vet Camp, a 7-day residential summer camp for students entering eighth or ninth grade in the fall, would increase participants' understanding of career options in the veterinary profession, increase understanding of the science of veterinary medicine, or increase the number of students stating that they intended to apply to the Purdue University School of Veterinary Medicine. Survey. 48 individuals attending the 2009 Boiler Vet Camp. Information on participant demographics was obtained from camp applications. A questionnaire was administered on the first and sixth days of camp, and results were analyzed to identify changes in responses over time. More campers correctly answered questions designed to evaluate knowledge of the veterinary profession and 10 of 12 questions designed to evaluate specific knowledge of the science of veterinary medicine on day 6, compared with day 1. Remarkable differences were not observed among gender or race-ethnicity groups for these questions. There was no significant difference between percentages of campers who stated that they would apply to Purdue before and after camp. Significantly more Caucasian campers stated they would apply to Purdue on both day 1 and day 6, compared with campers from under-represented minority groups. Results indicated that the Boiler Vet Camp accomplished 2 of its 3 planned objectives, suggesting that such camps can be successfully used to increase knowledge of the veterinary profession among middle school students. Reasons for the low percentage of participants from underrepresented minorities who indicated they would apply to the Purdue University School of Veterinary Medicine require further exploration.

1998-01-01

The ultrastructure of the endolymphatic sac (ES) of the late stage larva of the Japanese red-bellied newt, Cynops pyrrhogaster (stage 57), was examined by light and transmission electron microscopy. The two endolymphatic sacs are located at the dorsal-medial side of the otic vesicle on the dorsal-lateral side of the midbrain in the cranial cavity. The wall of the sac is composed of a layer of cubical epithelial cells with loose, interposed intercellular spaces. The sac contains a large luminal cavity, in which endolymph and numerous otoconia are present. The epithelial cells of different portions of the sac have a similar structure. These cells contain an abundance of cytoplasmic organelles, including ribosomes, Golgi complexes, and numerous vesicles. Two types of vesicles are found in the epithelial cells: the "floccular" vesicle and the "granular" vesicle. The floccular vesicles are located in the supra- and lateral-nuclear cytoplasm and contain floccular material. The granular vesicles have a fine granular substance and are usually situated apposed to the apical cell membrane. The granular vesicles are suggested to be secreted into the lumen, while the floccular vesicles are thought to be absorbed from the lumen and conveyed to the intercellular spaces by the epithelial cells. The apical surfaces of the epithelial cells bear numerous microvilli. Apparently floating cells, which bear long microvilli on the free surfaces, are observed in the lumen of the ES. Based on the fine structure, the function of the endolymphatic sac of the newt Cynops pyrrhogaster is discussed.

Altered callose deposition during embryo sac formation of multi-pistil mutant (mp1) in Medicago sativa.

Zhou, H C; Jin, L; Li, J; Wang, X J

2016-06-03

Whether callose deposition is the cause or result of ovule sterility in Medicago sativa remains controversial, because it is unclear when and where changes in callose deposition and dissolution occur during fertile and sterile embryo sac formation. Here, alfalfa spontaneous multi-pistil mutant (mp1) and wild-type plants were used to compare the dynamics of callose deposition during embryo sac formation using microscopy. The results showed that both mutant and wild-type plants experienced megasporogenesis and megagametogenesis, and there was no significant difference during megasporogenesis. In contrast to the wild-type plants, in which the mature embryo sac was observed after three continuous cycles of mitosis, functional megaspores of mutant plants developed abnormally after the second round of mitosis, leading to degeneration of synergid, central, and antipodal cells. Callose deposition in both mutant and wild-type plants was first observed in the walls of megasporocytes, and then in the megaspore tetrad walls. After meiosis, the callose wall began to degrade as the functional megaspore underwent mitosis, and almost no callose was observed in the mature embryo sac in wild-type plants. However, callose deposition was observed in mp1 plants around the synergid, and increased with the development of the embryo sac, and was mainly deposited at the micropylar end. Our results indicate that synergid, central, and antipodal cells, which are surrounded by callose, may degrade owing to lack of nutrition. Callose accumulation around the synergid and at the micropylar end may hinder signals required for the pollen tube to enter the embryo sac, leading to abortion.

One of the new features of this receiver is its ability to sense the lower troposphere closer to the surface than the proof-of-concept GPS Meteorology experiment (GPS/MET). Since their launch, CHAMP and SAC-C have collected thousands of GPS radio occultations, representing a wealth of measurements available for data assimilation and Numerical Weather Prediction (NWP). In order to evaluate the refractivity data derived by the Jet Propulsion Laboratory (JPL) from raw radio occultation measurements, we use Data Assimilation Office (DAO) 6-hour forecasts as an independent state of the atmosphere. We compare CHAMP and SAC-C refractivity (processed by JPL) with refractivity calculated from the DAO global fields of temperature, water vapor content and humidity. We show statistics of the differences as well as histograms of the differences.

2000-01-01

In the course of the last two centuries veterinarians succeeded in gaining a monopoly with respect to a number of specific tasks within society under the motto "to the benefit of man and animal alike". Today, a veterinary infrastructure exists in the western world, which is usually taken for granted by society. Before the responsibility for maintaining animal resources and protecting both animal and human health were entrusted to veterinarians, both the process of scientific progress and professionalization of veterinary medicine were necessary. In this paper the regulation of the market for veterinary services in The Netherlands is decribed. Until World War II, the military and the colonies represented a major demand for veterinary services. A healthly livestock has always been considered as a main concern by the Dutch government with respect to the domestic food supply as well as exports. State intervention concerning veterinary medicine therefore focused on the organized campaigns against livestock diseases. Early national veterinary legislation originated from this concern, as is still the case today within the EU framework. The protection of human health only became part of the veterinary professional domain at a relatively late stage. Due to a strong economic growth from the 1960s onwards, veterinary practice was extended with the care for an increasing number of companion animals. The veterinary profession and its employment are subject to changes in society, such as the number of animals and the significance that is paid to the different species. In 1900 there were 4 million production animals in The Netherlands, while the human population counted 5 million. One century later, not less than approximately 130 million farm animals and 30 million companion animals are living in this country, which now has about 16 million inhabitants. Consquently, the total number of active vets increased from about 250 to 4,000 in the same period, while the number of group

Simple Summary First initiated in 1995 to provide veterinary students with spay/neuter experience, the shelter program at the Mississippi State University College of Veterinary Medicine has grown to be comprehensive in nature incorporating spay/neuter, basic wellness care, diagnostics, medical management, disease control, shelter management and biosecurity. Junior veterinary students spend five days in shelters; senior veterinary students spend 2-weeks visiting shelters in mobile veterinary units. The program has three primary components: spay/neuter, shelter medical days and Animals in Focus. Student gain significant hands-on experience and evaluations of the program by students are overwhelmingly positive. Abstract The shelter program at the Mississippi State University College of Veterinary Medicine provides veterinary students with extensive experience in shelter animal care including spay/neuter, basic wellness care, diagnostics, medical management, disease control, shelter management and biosecurity. Students spend five days at shelters in the junior year of the curriculum and two weeks working on mobile veterinary units in their senior year. The program helps meet accreditation standards of the American Veterinary Medical Association’s Council on Education that require students to have hands-on experience and is in keeping with recommendations from the North American Veterinary Medical Education Consortium. The program responds, in part, to the challenge from the Pew Study on Future Directions for Veterinary Medicine that argued that veterinary students do not graduate with the level of knowledge and skills that is commensurate with the number of years of professional education.

Veterinary parasitology has always been considered to be relevant and interesting by the Danish veterinary students. Students have to acquaint themselves with many new, small creatures with complicated and varied life cycles and with intricate Latin names that are difficult to pronounce, as only a few parasites have Danish names. In our veterinary curriculum, zoology has disappeared as a discipline, and parasitology has gradually moved from the third year to the beginning of the second year, which implies that, for example, pathology and pharmacology are "unknown fields". The number of contact hours in veterinary parasitology has been gradually cut to 24 lectures (35 min each) and practical exercises (24 h), including 9 h on coprology. The course is taught and examined jointly with bacteriology and virology in a 8-week course. As a comprehensive course, it has become increasingly difficult to get students to acquire enough active knowledge of the most common parasites and an understanding of the basic principles in relation to, for example, transmission and control. Even though information is readily accessible through books and on-line resources, we still believe that a competent clinician should know a range of parasites by heart as an active resource for their work. The dilemma has been tackled (partly) by introducing a veterinary paraclinical refresher course of 18 h (half practicals and half lectures) in the fourth study year. The focus here is on host(herd)-oriented clinical and diagnostic parasitology. The students can also now select a One Health track for six months in which zoonotic parasites are obviously a relevant topic. Copyright © 2018. Published by Elsevier B.V.

β-Globin-Expressing Definitive Erythroid Progenitor Cells Generated from Embryonic and Induced Pluripotent Stem Cell-Derived Sacs.

Human embryonic stem (ES) cells and induced pluripotent stem (iPS) cells represent a potential alternative source for red blood cell transfusion. However, when using traditional methods with embryoid bodies, ES cell-derived erythroid cells predominantly express embryonic type ɛ-globin, with lesser fetal type γ-globin and very little adult type β-globin. Furthermore, no β-globin expression is detected in iPS cell-derived erythroid cells. ES cell-derived sacs (ES sacs) have been recently used to generate functional platelets. Due to its unique structure, we hypothesized that ES sacs serve as hemangioblast-like progenitors capable to generate definitive erythroid cells that express β-globin. With our ES sac-derived erythroid differentiation protocol, we obtained ∼120 erythroid cells per single ES cell. Both primitive (ɛ-globin expressing) and definitive (γ- and β-globin expressing) erythroid cells were generated from not only ES cells but also iPS cells. Primitive erythropoiesis is gradually switched to definitive erythropoiesis during prolonged ES sac maturation, concurrent with the emergence of hematopoietic progenitor cells. Primitive and definitive erythroid progenitor cells were selected on the basis of glycophorin A or CD34 expression from cells within the ES sacs before erythroid differentiation. This selection and differentiation strategy represents an important step toward the development of in vitro erythroid cell production systems from pluripotent stem cells. Further optimization to improve expansion should be required for clinical application. Stem Cells 2016;34:1541-1552. © 2016 AlphaMed Press.

Correlation of two bioadhesion assays: the everted sac technique and the CAHN microbalance.

This contribution correlates two in vitro methods utilized to determine bioadhesion. One method, the everted intestinal sac technique, is a passive test for bioadhesion involving several polymer microspheres and a section of everted intestinal tissue. The other method, the CAHN microbalance, employs a CAHN dynamic contact angle analyzer with modified software to record the tensile forces measured as a single polymer microsphere is pulled from intestinal tissue. This study demonstrates that CAHN and everted sac experiments yield similar results when used to quantify the bioadhesive nature of polymer microsphere systems. A polymer showing high adhesion in one method also demonstrates high bioadhesion in the other method; polymers that exhibit high fracture strength and tensile work measurements with the CAHN microbalance also yield high binding percentages with the everted sac method. The polymers tested and reported here are poly(caprolactone) and different copolymer ratios of poly(fumaric-co-sebacic anhydride). The results of this correlation demonstrate that each method alone is a valuable indicator of bioadhesion.

This article describes the results of a whisker formation study on SAC305 assemblies, evaluating the effects of lead-frame materials and cleanliness in different environments: low-stress simulated power cycling (50-85°C thermal cycling), thermal shock (-55°C to 85°C), and high temperature/high humidity (85°C/85% RH). Cleaned and contaminated small outline transistors, large leaded quad flat packs (QFP), plastic leaded chip carrier packages, and solder balls with and without rare earth elements (REE) were soldered to custom designed test boards with Sn3Ag0.5Cu (SAC305) solder. After assembly, all the boards were cleaned, and half of them were recontaminated (1.56 µg/cm2 Cl-). Whisker length, diameter, and density were measured. Detailed metallurgical analysis on components before assembly and on solder joints before and after testing was performed. It was found that whiskers grow from solder joint fillets, where the thickness is less than 25 µm, unless REE was present. The influence of lead-frame and solder ball material, microstructure, cleanliness, and environment on whisker characteristics is discussed. This article provides detailed metallurgical observations and select whisker length data obtained during this multiyear testing program.

Acceptance rate and reasons for rejection of manuscripts submitted to Veterinary Radiology & Ultrasound during 2012.

PubMed

Lamb, Christopher R; Mai, Wilfried

2015-01-01

Better understanding of the reasons why manuscripts are rejected, and recognition of the most frequent manuscript flaws identified by reviewers, should help submitting authors to avoid these pitfalls. Of 219 manuscripts submitted to Veterinary Radiology & Ultrasound in 2012, none (0%) was accepted without revision, four (2%) were withdrawn by the authors, 99 (45%) were accepted after revision, and 116 (53%) were rejected. All manuscripts for which minor revision was requested, and 73/86 (85%) manuscripts for which major revision was requested, were ultimately accepted. Acceptance rate was greater for retrospective studies and for manuscripts submitted from countries in which English was the primary language. The prevalences of flaws in manuscripts were poor writing (62%), deficiencies in data (60%), logical or methodological errors (28%), content not suitable for Veterinary Radiology & Ultrasound (26%), and lack of new or useful knowledge (25%). Likelihood of manuscript rejection was greater for lack of new or useful knowledge and content not suitable than for other manuscript flaws. The lower acceptance rate for manuscripts from countries in which English was not the primary language was associated with content not suitable and not poor writing. Submitting authors are encouraged to do more to recognize and address manuscript flaws before submission, for example by internal review. Specifically, submitting authors should express clearly the potential added value of their study in the introduction section of their manuscript, describe completely their methods and results, and consult the Editor-in-Chief if they are uncertain whether their subject matter would be suitable for the journal. © 2014 American College of Veterinary Radiology.

Career identity in the veterinary profession.

Page-Jones, S; Abbey, G

2015-04-25

This research investigates vet and vet nurse career identity through the qualitative methodology of narrative enquiry. It derives learning and understanding from these empirical data to assist the veterinary profession to adjust to the changing industry landscape. Through a case series of 20 vets and vet nurses' career stories, this paper seeks understanding about career identity and its impact on individuals and organisations in the light of industry consolidation. Findings suggest that career is central to identity for many veterinary professionals who tend to have a strong sense of self; this is particularly evident around self as learner and technically competent, teacher and educator, ethical and moral and dedicated and resilient. Consequently, mismatches between 'who I am' and 'what I do' tend not to lead to identity customisation (to fit self into role or organisation) but to the search for alternative, more identity-compatible employment. This study offers a valuable insight for employers, veterinary professionals and universities. It suggests that businesses can gain competitive advantage and employees achieve validation and enrichment by working towards organisational and individual identity congruence and that teaching veterinary professionals with contemporary business in mind may develop graduates with a more sustainable identity.

In the present study, the effects of red and blue LED lights on the accumulation of ascorbic acid (AsA) were investigated in the juice sacs of three citrus varieties, Satsuma mandarin, Valencia orange, and Lisbon lemon. The results showed that the blue LED light treatment effectively increased the AsA content in the juice sacs of the three citrus varieties, whereas the red LED light treatment did not. By increasing the blue LED light intensity, the juice sacs of the three citrus varieties accumulated more AsA. Moreover, continuous irradiation with blue LED light was more effective than pulsed irradiation for increasing the AsA content in the juice sacs of the three citrus varieties. Gene expression results showed that the modulation of AsA accumulation by blue LED light was highly regulated at the transcription level. The up-regulation of AsA biosynthetic genes (CitVTC1, CitVTC2, CitVTC4, and CitGLDH), AsA regeneration genes (CitMDAR1, CitMDAR2, and CitDHAR) and two GSH-producing genes (CitGR and CitchGR) contributed to these increases in the AsA content in the three citrus varieties.

2016-11-01

Apocrine gland adenocarcinoma of the anal sac (AGAAS) is associated with high rates of iliosacral lymph node metastasis, which may influence treatment and prognosis. Magnetic resonance imaging (MRI) recently has been shown to be more sensitive than abdominal ultrasound examination (AUS) in affected patients. To compare the rate of detection of iliosacral lymphadenomegaly between AUS and computed tomography (CT) in dogs with AGAAS. Cohort A: A total of 30 presumed normal dogs. Cohort B: A total of 20 dogs with AGAAS that underwent AUS and CT. Using cohort A, mean normalized lymph node : aorta (LN : AO) ratios were established for medial iliac, internal iliac, and sacral lymph nodes. The CT images in cohort B then were reviewed retrospectively and considered enlarged if their LN : AO ratio measured 2 standard deviations above the mean normalized ratio for that particular node in cohort A. Classification and visibility of lymph nodes identified on AUS were compared to corresponding measurements obtained on CT. Computed tomography identified lymphadenomegaly in 13 of 20 AGAAS dogs. Of these 13 dogs, AUS correctly identified and detected all enlarged nodes in only 30.8%, and either misidentified or failed to detect additional enlarged nodes in the remaining dogs. Despite limitations in identifying enlargement in all affected lymph nodes, AUS identified at least 1 enlarged node in 100% of affected dogs. Abdominal ultrasound examination is an effective screening test for lymphadenomegaly in dogs with AGAAS, but CT should be considered in any patient in which an additional metastatic site would impact therapeutic planning.

Cancer treatments in veterinary medicine continue to evolve beyond the established standard therapies of surgery, chemotherapy and radiation therapy. New technologies in cancer therapy include a targeted mechanism to open the cell membrane based on electroporation, driving therapeutic agents, such as chemotherapy (electro-chemotherapy), for local control of cancer, or delivery of gene-based products (electro-gene therapy), directly into the cancer cell to achieve systemic control. This review examines electrochemotherapy and electro-gene therapy in veterinary medicine and considers future directions and applications. Copyright © 2016 Elsevier Ltd. All rights reserved.

Veterinary pharmacology: history, current status and future prospects.

Veterinary therapeutics, based on the art of Materia Medica, has been practised for countless centuries, but the science of veterinary pharmacology is of very recent origin. This review traces the contribution of Materia Medica to veterinary therapeutics from the Egyptian period through to the Age of Enlightenment. The first tentative steps in the development of the science of veterinary pharmacology were taken in the 18th century, but it was not until the mid 20th century that the science replaced the art of Materia Medica. This review traces the 20th century developments in veterinary pharmacology, with emphasis on the explosion of knowledge in the 35 year period to 2010. The range of factors which have influenced the current status of the discipline are reviewed. Future developments are considered from the perspectives of what might be regarded as desirable and those innovations that might be anticipated. We end with words of encouragement for young colleagues intent upon pursuing a career in veterinary pharmacology. © 2013 Blackwell Publishing Ltd.

A Decade of Counseling Services in One College of Veterinary Medicine: Veterinary Medical Students' Psychological Distress and Help-Seeking Trends.

PubMed

Drake, Adryanna A S; Hafen, McArthur; Rush, Bonnie R

Much has been discussed about the high prevalence of psychological distress among veterinary medical students. Studies investigating general samples of veterinary medical students indicate that, on average, depression and anxiety symptoms are present at higher rates than in comparison samples. However, little is known about veterinary medical students who seek counseling. This study intends to expand the literature on veterinary student well-being, as the first to examine a sample of veterinary medical students seeking counseling services. It offers an overview of student distress and help-seeking trends from a decade of counseling services provided in one College of Veterinary Medicine (CVM) in the US. The sample includes data from 279 participants. Results indicate a steady increase in students seeking counseling over the last decade. First-year students sought services at higher rates but second-year students experienced the greatest distress when compared to other cohorts. Students seeking counseling services experienced levels of overall distress, symptoms of anxiety and depression, and social role concerns that were, on average, above cut-off scores. Physical health was significantly associated with student distress, suggesting opportunities for intervention.

2002-01-01

The Little Sac River, north of Springfield, Missouri, flows through mainly agricultural and forest land. However, the quality of the river water is a concern because the river flows into Stockton Lake, which is a supplemental drinking water source for Springfield. Large bacterial densities and nutrient concentrations are primary concerns to the water quality of the river.A 29-river mile reach of the Little Sac River is on the 1998 list of waters of Missouri designated under section 303(d) of the Federal Clean Water Act because of fecal coliform densities larger than the Missouri Department of Natural Resources standard (hereinafter referred to as Missouri standard) of 200 colonies per 100 milliliters for whole-body contact recreation. During an investigation of the water quality in the Little Sac River by the U.S. Geological Survey, in cooperation with the Watershed Committee of the Ozarks, fecal coliform bacteria densities exceeded the Missouri standard (the standard applies from April 1 through October 31) in one sample from a site near Walnut Grove. At other sites on the Little Sac River, the Missouri standard was exceeded in two samples and equalled in one sample upstream from the Northwest Wastewater Treatment Plant (NW WTP) and in one sample immediately downstream from the NW WTP.Effluent from the NW WTP flows into the Little Sac River. Annually from April 1 through October 31, the effluent is disinfected to meet the Missouri standard for whole-body contact recreation. Fecal coliform bacteria densities in samples collected during this period generally were less than 100 colonies per 100 milliliters. For the rest of the year when the effluent was not disinfected, the bacteria densities in samples ranged from 50 (sample collected on November 1, 2000) to 10,100 colonies per 100 milliliters (both counts were non-ideal). When the effluent was disinfected and the fecal coliform bacteria density was small, samples from sites upstream and downstream from the NW WTP

2017-07-26

Globally pharmacists are becoming increasingly involved in veterinary medicine; however, little is known about the level of interest for pharmacists playing a larger role in animal treatment in New Zealand. A key stakeholder in any progression of pharmacists becoming more involved in the practice of veterinary pharmacy is the veterinary profession. The aim of this study was to investigate views of veterinarians and veterinary students on the role of pharmacists supporting veterinarians with advice on animal medicines. Open interviews were conducted with veterinarians in Dunedin, New Zealand. Veterinary students at Massey University completed an online survey. Most veterinarians do not have regular communication with pharmacists regarding animal care, but believe it may be beneficial. In order to support veterinarians, pharmacists would need further education in veterinary medicine. Veterinary students believe there is opportunity for collaboration between professions provided that pharmacists have a better working knowledge of animal treatment. Most of the veterinary students surveyed perceive a gap in their knowledge concerning animal medicines, specifically pharmacology and compounding. While there is support for pharmacists contributing to veterinary medicine, particularly in the area of pharmaceutics, this is currently limited in New Zealand due to a lack of specialized education opportunities.

Current Status of Veterinary Vaccines

Meeusen, Els N. T.; Walker, John; Peters, Andrew; Pastoret, Paul-Pierre; Jungersen, Gregers

2007-01-01

The major goals of veterinary vaccines are to improve the health and welfare of companion animals, increase production of livestock in a cost-effective manner, and prevent animal-to-human transmission from both domestic animals and wildlife. These diverse aims have led to different approaches to the development of veterinary vaccines from crude but effective whole-pathogen preparations to molecularly defined subunit vaccines, genetically engineered organisms or chimeras, vectored antigen formulations, and naked DNA injections. The final successful outcome of vaccine research and development is the generation of a product that will be available in the marketplace or that will be used in the field to achieve desired outcomes. As detailed in this review, successful veterinary vaccines have been produced against viral, bacterial, protozoal, and multicellular pathogens, which in many ways have led the field in the application and adaptation of novel technologies. These veterinary vaccines have had, and continue to have, a major impact not only on animal health and production but also on human health through increasing safe food supplies and preventing animal-to-human transmission of infectious diseases. The continued interaction between animals and human researchers and health professionals will be of major importance for adapting new technologies, providing animal models of disease, and confronting new and emerging infectious diseases.

Veterinary school consortia as a means of promoting the food-supply veterinary medicine pipeline.

PubMed

Moore, Dale A

2006-01-01

Ideas about centers of emphasis and veterinary medical teaching consortia have resurfaced to attract students into food-supply veterinary medicine (FSVM). From 1988 to 2000 a multiple veterinary school consortium approach to food-animal production medicine (FAPM) teaching was conducted to handle regional differences in case load, faculty strengths, and student interests. Six universities developed a memorandum of understanding to provide a wide variety of in-depth, species-specific clinical experiences in FAPM to balance their individual strengths and weakness in addressing food-animal agriculture, to provide for student exchange and faculty development, and to conduct research in food safety. Changes in leadership, redirection of funds, failure to publicize the program to faculty and students, and a focus on research as opposed to teaching led to dissolution of the consortium. However, this approach could work to improve recruitment and retention of students in FSVM if it focused on student exchange, fostered a more integrated curriculum across schools, encouraged faculty involvement, garnered institutional support, and used modern technology in teaching. Private veterinary practices as well as public/corporate practices could be integrated into a broader food-animal curriculum directed at building competency among FSVM students by providing the in-depth training they require. Requirements for the success of this type of program will include funding, marketing, leadership, communication, coordination, integration, and dedicated people with the time to make it work.

Crystal plasticity finite element analysis of deformation behaviour in SAC305 solder joint

NASA Astrophysics Data System (ADS)

Darbandi, Payam

Due to the awareness of the potential health hazards associated with the toxicity of lead (Pb), actions have been taken to eliminate or reduce the use of Pb in consumer products. Among those, tin (Sn) solders have been used for the assembly of electronic systems. Anisotropy is of significant importance in all structural metals, but this characteristic is unusually strong in Sn, making Sn based solder joints one of the best examples of the influence of anisotropy. The effect of anisotropy arising from the crystal structure of tin and large grain microstructure on the microstructure and the evolution of constitutive responses of microscale SAC305 solder joints is investigated. Insights into the effects of key microstructural features and dominant plastic deformation mechanisms influencing the measured relative activity of slip systems in SAC305 are obtained from a combination of optical microscopy, orientation imaging microscopy (OIM), slip plane trace analysis and crystal plasticity finite element (CPFE) modeling. Package level SAC305 specimens were subjected to shear deformation in sequential steps and characterized using optical microscopy and OIM to identify the activity of slip systems. X-ray micro Laue diffraction and high energy monochromatic X-ray beam were employed to characterize the joint scale tensile samples to provide necessary information to be able to compare and validate the CPFE model. A CPFE model was developed that can account for relative ease of activating slip systems in SAC305 solder based upon the statistical estimation based on correlation between the critical resolved shear stress and the probability of activating various slip systems. The results from simulations show that the CPFE model developed using the statistical analysis of activity of slip system not only can satisfy the requirements associated with kinematic of plastic deformation in crystal coordinate systems (activity of slip systems) and global coordinate system (shape changes

To determine the rabies vaccination status of Queensland veterinarians and veterinary students and their perception of zoonotic risk from Australian bat lyssavirus (ABLV). Cross-sectional questionnaire surveys. Questionnaires were sent by post in 2011 to veterinary surgeons registered in Queensland, to final-year veterinary students at James Cook University via SurveyMonkey® in 2013 and to final-year veterinary students at James Cook University and University of Queensland via SurveyMonkey® in 2014. The response rate for registered veterinarians was 33.5% and for veterinary students 33.3% and 30% in 2013 and 2014, respectively. Of the 466 registered veterinary surgeons, 147 (31.5%) had been vaccinated, with 72 (15.5%) currently vaccinated. For veterinary students the rabies vaccination rate was 20.0% (4/20) and 13.0% (6/46) in the 2013 and 2014 surveys, respectively. More than 95% of veterinary students had received the mandatory Q fever vaccine. Both veterinarians and students regarded bats and horses as high-risk species for zoonoses. Queensland veterinarians and veterinary students have low levels of protection against ABLV. Although incidents of ABLV spilling over from a bat to a domestic mammal are likely to remain rare, they pose a significant human health and occupational risk given the outcome of infection in humans is high consequence. Principals of veterinary practices and veterinary authorities in Australia should implement a policy of rabies vaccination for clinical staff and veterinary students. © 2018 Australian Veterinary Association.

The establishment of coral sperm repositories which retain good post-rewarming viability and fertility play a vital role in species conservation. This study aimed at obtaining baseline information regarding the effects of cryoprotectant agents (CPAs) on gorgonian coral (Junceella juncea and J. fragilis) sperm sacs. The adenosine triphosphate assay was used to determine the energy level of the gorgonian sperm sacs as an indicator of sperm viability after exposure to cryoprotectants. The 'no observed effect concentrations' (NOECs) of methanol, dimethyl sulfoxide (DMSO), polypropylene glycol (PG), ethylene glycol (EG) and glycerol for J. juncea sperm sacs were 3 M, 3 M, 1 M, 2 M and 1 M respectively after 20 min exposure; whilst the NOECs for J. fragilis oocytes were 2 M, 3 M, 1 M, 2 M and 2 M, respectively. Methanol and DMSO had the least impact. PG was the most toxic CPA after 10 min exposure. ATP content of J. juncea and J. fragilis sperm sacs did not differ significantly from the control with incubation times of 10-20 min with 2 M EG. However, ATP content dropped significantly after exposing sperm sacs to 2 M EG for 40 min with average values of 2.34 +/- 0.12 and 1.97 +/- 0.48 microg/ml respectively. ATP content for J. juncea and J. fragilis sperm sacs was significantly decreased to 1.79 +/- 0.31 and 2.40 +/- 0.36 microg/ml after 20 min incubation in 2 M PG when compared to the control with 2.98 +/- 0.16 and 4.14 +/- 0.42 microg/ml respectively. Normalized ATP content for sperm sacs of two different gorgonian coral after incubation in methanol, DMSO, PG, EG and glycerol showed that J. juncea sperm sacs were slightly less tolerant to CPAs compared to J. fragilis sperm sacs. DMSO or methanol can be considered as efficient CPAs for gorgonian sperm sacs cryopreservation. The ATP luminescence assay provided sensitive and rapid quantification of mitochondrial activity in gorgonian coral sperm sacs. The study on the impact of CPA will contribute to the development of a

Distal Regeneration Involves the Age Dependent Activity of Branchial Sac Stem Cells in the Ascidian Ciona intestinalis.

PubMed

Jeffery, William R

2015-02-01

Tunicates have high capacities for regeneration but the underlying mechanisms and their relationship to life cycle progression are not well understood. Here we investigate the regeneration of distal structures in the ascidian tunicate Ciona intestinalis . Analysis of regenerative potential along the proximal-distal body axis indicated that distal organs, such as the siphons, their pigmented sensory organs, and the neural complex, could only be replaced from body fragments containing the branchial sac. Distal regeneration involves the formation of a blastema composed of cells that undergo cell proliferation prior to differentiation and cells that differentiate without cell proliferation. Both cell types originate in the branchial sac and appear in the blastema at different times after distal injury. Whereas the branchial sac stem cells are present in young animals, they are depleted in old animals that have lost their regeneration capacity. Thus Ciona adults contain a population of age-related stem cells located in the branchial sac that are a source of precursors for distal body regeneration.

Many open source software packages have been recently developed to expand the usability of eye tracking systems to study oculomotor behavior, but none of these is specifically designed to encompass all the main functions required for creating eye tracking tests and for providing the automatic analysis of saccadic eye movements. The aim of this study is to introduce SacLab, an intuitive, freely-available MATLAB toolbox based on Graphical User Interfaces (GUIs) that we have developed to increase the usability of the ViewPoint EyeTracker (Arrington Research, Scottsdale, AZ, USA) in clinical ophthalmology practice. SacLab consists of four processing modules that enable the user to easily create visual stimuli tests (Test Designer), record saccadic eye movements (Data Recorder), analyze the recorded data to automatically extract saccadic parameters of clinical interest (Data Analyzer) and provide an aggregate analysis from multiple eye movements recordings (Saccade Analyzer), without requiring any programming effort by the user. A demo application of SacLab to carry out eye tracking tests for the analysis of horizontal saccades was reported. We tested the usability of SacLab toolbox with three ophthalmologists who had no programming experience; the ophthalmologists were briefly trained in the use of SacLab GUIs and were asked to perform the demo application. The toolbox gained an enthusiastic feedback from all the clinicians in terms of intuitiveness, ease of use and flexibility. Test creation and data processing were accomplished in 52±21s and 46±19s, respectively, using the SacLab GUIs. SacLab may represent a useful tool to ease the application of the ViewPoint EyeTracker system in clinical routine in ophthalmology. Copyright © 2016 Elsevier Ltd. All rights reserved.

Stretch induced endothelin-1 secretion by adult rat astrocytes involves calcium influx via stretch-activated ion channels (SACs)

Highlights: {yields} Endothelin-1 expression by adult rat astrocytes correlates with cell proliferation. {yields} Stretch-induced ET-1 is inhibited by GsMtx-4, a specific inhibitor of Ca{sup 2+} permeant SACs. {yields} The less specific SAC inhibitor streptomycin also inhibits ET-1 secretion. {yields} Stretch-induced ET-1 production depends on a calcium influx. {yields} SAC pharmacology may provide a new class of therapeutic agents for CNS pathology. -- Abstract: The expression of endothelins (ETs) and ET-receptors is often upregulated in brain pathology. ET-1, a potent vasoconstrictor, also inhibits the expression of astrocyte glutamate transporters and is mitogenic for astrocytes, glioma cells, neurons, and brain capillary endothelia.more » We have previously shown that mechanical stress stimulates ET-1 production by adult rat astrocytes. We now show in adult astrocytes that ET-1 production is driven by calcium influx through stretch-activated ion channels (SACs) and the ET-1 production correlates with cell proliferation. Mechanical stimulation using biaxial stretch (<20%) of a rubber substrate increased ET-1 secretion, and 4 {mu}M GsMTx-4 (a specific inhibitor of SACs) inhibited secretion by 30%. GsMTx-4 did not alter basal ET-1 levels in the absence of stretch. Decreasing the calcium influx by lowering extracellular calcium also inhibited stretch-induced ET-1 secretion without effecting ET-1 secretion in unstretched controls. Furthermore, inhibiting SACs with the less specific inhibitor streptomycin also inhibited stretch-induced ET-1 secretion. The data can be explained with a simple model in which ET-1 secretion depends on an internal Ca{sup 2+} threshold. This coupling of mechanical stress to the astrocyte endothelin system through SACs has treatment implications, since all pathology deforms the surrounding parenchyma.« less

2014-09-01

Integrative medicine is the combined use of complementary and alternative medicine with conventional or traditional Western medicine systems. The demand for integrative veterinary medicine is growing, but evidence-based research on its efficacy is limited. In veterinary clinical oncology, such research could be translated to human medicine, because veterinary patients with spontaneous tumors are valuable translational models for human cancers. An overview of specific herbs, botanics, dietary supplements, and acupuncture evaluated in dogs, in vitro canine cells, and other relevant species both in vivo and in vitro is presented for their potential use as integrative therapies in veterinary clinical oncology.

Bone histological correlates for air sacs and their implications for understanding the origin of the dinosaurian respiratory system.

Lambertz, Markus; Bertozzo, Filippo; Sander, P Martin

2018-01-01

Air sacs are an important component of the avian respiratory system, and corresponding structures also were crucial for the evolution of sauropod dinosaur gigantism. Inferring the presence of air sacs in fossils so far is restricted to bones preserving internal pneumatic cavities and foramina as osteological correlates. We here present bone histological correlates for air sacs as a new potential identification tool for these elements of the respiratory system. The analysis of several avian and non-avian dinosaur samples revealed delicate fibres in secondary trabecular and secondary endosteal bone that in the former case (birds) is known or in the latter (non-avian dinosaurs) assumed to have been in contact with air sacs, respectively. The bone histology of this 'pneumosteal tissue' is markedly different from those regions where muscles attached presenting classical Sharpey's fibres. The pneumatized bones of several non-dinosaurian taxa do not exhibit the characteristics of this 'pneumosteum'. Our new histology-based approach thus can be instrumental in reconstructing the origin of air sacs among dinosaurs and hence for our understanding of this remarkable evolutionary novelty of the respiratory system. © 2018 The Author(s).

For many vertebrates the lung is the largest and lightest organ in the body cavity and for these reasons can greatly affect an organism's shape, density, and its distribution of mass; characters that are important to locomotion. In this paper non-respiratory functions of the lung are considered along with data on the respiratory capacities and gas exchange abilities of birds and crocodilians to infer the evolutionary history of the respiratory systems of dinosaurs, including birds. From a quadrupedal ancestry theropod dinosaurs evolved a bipedal posture. Bipedalism is an impressive balancing act, especially for tall animals with massive heads. During this transition selection for good balance and agility may have helped shape pulmonary morphology. Respiratory adaptations arising for bipedalism are suggested to include a reduction in costal ventilation and the use of cuirassal ventilation with a caudad expansion of the lung into the dorsal abdominal cavity. The evolution of volant animals from bipeds required yet again a major reorganization in body form. With this transition avian air sacs may have been favored because they enhanced balance and agility in flight. Finally, I propose that these hypotheses can be tested by examining the importance of the air sacs to balance and agility in extant animals and that these data will enhance our understanding of the evolution of the respiratory system in archosaurs.

Objectives: To explore and gain an understanding of what “clinical communication skills” mean to veterinarians working in private practice and what implications this might have for veterinary medical education. Methods: Qualitative research methods were used to purposefully sample a range of veterinary practitioners from a pool of South Australian veterinary practices who were interviewed to determine their understanding of what communication skills mean in the context of veterinary practice. Interviews were conducted with fourteen veterinary practitioners. Participants were sampled from a range of ages, veterinary schools of graduation plus urban and rural locations. Interview transcripts were analysed for themes, definitions and contexts. Results: Participants’ accounts included a number of skills which they considered to be “communication”. Some of the definitions of these skills parallel communication skills and competencies for human medicine on which communication skills training incorporated into veterinary curricula to date have largely been based. However, the veterinarians in this study also raised interesting contextual differences unique to the veterinary profession, such as communication with the animal, selling service, discussing money in relation to decisions for care, and communicating about euthanasia. Conclusions: Veterinary practitioners require high level communication skills. Education and training in veterinary medicine may be better tailored to reflect the unique context of the veterinary profession. PMID:25341230

Research data services in veterinary medicine libraries.

Kerby, Erin E

2016-10-01

The study investigated veterinary medicine librarians' experience with and perceptions of research data services. Many academic libraries have begun to offer research data services in response to researchers' increased need for data management support. To date, such services have typically been generic, rather than discipline-specific, to appeal to a wide variety of researchers. An online survey was deployed to identify trends regarding research data services in veterinary medicine libraries. Participants were identified from a list of contacts from the MLA Veterinary Medical Libraries Section. Although many respondents indicated that they have a professional interest in research data services, the majority of veterinary medicine librarians only rarely or occasionally provide data management support as part of their regular job responsibilities. There was little consensus as to whether research data services should be core to a library's mission despite their perceived importance to the advancement of veterinary research. Furthermore, most respondents stated that research data services are just as or somewhat less important than the other services that they provide and feel only slightly or somewhat prepared to offer such services. Lacking a standard definition of "research data" and a common understanding of precisely what research data services encompass, it is difficult for veterinary medicine librarians and libraries to define and understand their roles in research data services. Nonetheless, they appear to have an interest in learning more about and providing research data services.

Antimicrobial susceptibility testing by Australian veterinary diagnostic laboratories.

The national strategy for tackling antimicrobial resistance highlights the need for antimicrobial stewardship in veterinary practice and for surveillance of antimicrobial susceptibility in veterinary pathogens. Diagnostic laboratories have an important role in facilitating both of these processes, but it is unclear whether data from veterinary diagnostic laboratories are similar enough to allow for compilation and if there is consistent promotion of appropriate antimicrobial use embedded in the approaches of different laboratories to susceptibility testing. A cross-sectional study of antimicrobial susceptibility testing and reporting procedures by Australian veterinary diagnostic laboratories was conducted in 2017 using an online questionnaire. All 18 veterinary diagnostic laboratories in Australia completed the questionnaire. Kirby-Bauer disc diffusion was the method predominantly used for antimicrobial susceptibility testing and was used to evaluate 86% of all isolates, although two different protocols were used across the 18 laboratories (CLSI 15/18, CDS 3/18). Minimum inhibitory concentrations were never reported by 61% of laboratories. Common isolates were consistently reported on across all species, except for gram-negative isolates in pigs, for which there was some variation in the approach to reporting. There was considerable diversity in the panels of antimicrobials used for susceptibility testing on common isolates and no consistency was apparent between laboratories for any bacterial species. We recommend that nationally agreed and consistent antimicrobial panels for routine susceptibility testing should be developed and a uniform set of guidelines should be adopted by veterinary diagnostic laboratories in Australia. © 2018 Australian Veterinary Association.

Low-lying π∗ resonances associated with cyano groups: A CAP/SAC-CI study

Ehara, Masahiro; Kanazawa, Yuki; Sommerfeld, Thomas

2017-01-01

The complex absorbing potential (CAP)/symmetry-adapted cluster-configuration interaction (SAC-CI) method is applied to low-lying π∗ resonance states of molecules containing one or two cyano (CN) groups. Benchmark calculations are carried out comparing the non-variational and approximate variational approach of SAC-CI and studying the selection threshold of operators. Experimental resonance positions from electron transmission spectroscopy (ETS) are reproduced provided the anticipated deviations due to vibronic effects are taken into account. Moreover, the calculated positions and widths agree well with those obtained in previous electron scattering calculations for HCN, CH3CN and their isonitriles. Based on our results, we suggest a reassignment of the experimental ETS of fumaronitrile and malononitrile. Our present results demonstrate again that the CAP/SAC-CI method reliably predicts low-lying π∗ resonances, and regarding the total numbers of molecules and resonances investigated, it is fair to say that it is presently the most extensively used high-level method in the temporary anion field.

Torsion of a hernia sac is an extremely rare condition that presents as acute scrotum in children. We report a case of a 6-year-old boy who presented with an acute scrotum and was found during surgical exploration to have torsion of an indirect hernia sac associated with hydrocele. Upon scrotal exploration, deterioration of the scrotum due to inflammatory changes was found. A necrotic cyst was recognized within a communicating hydrocele of the scrotum and was twisted at an angle of about 360°. All urologists should be aware of this special condition in the differential diagnosis of acute scrotum. PMID:23596604

Antimicrobial use in farm animals might contribute to the development of antimicrobial resistance in humans and animals, and there is an urgent need to reduce antimicrobial use in farm animals. Veterinarians are typically responsible for prescribing and overseeing antimicrobial use in animals. A thorough understanding of veterinarians' current prescribing practices and their reasons to prescribe antimicrobials might offer leads for interventions to reduce antimicrobial use in farm animals. This paper presents the results of a qualitative study of factors that influence prescribing behaviour of farm animal veterinarians. Semi-structured interviews with eleven farm animal veterinarians were conducted, which were taped, transcribed and iteratively analysed. This preliminary analysis was further discussed and refined in an expert meeting. A final conceptual model was derived from the analysis and sent to all the respondents for validation. Many conflicting interests are identifiable when it comes to antimicrobial prescribing by farm animal veterinarians. Belief in the professional obligation to alleviate animal suffering, financial dependency on clients, risk avoidance, shortcomings in advisory skills, financial barriers for structural veterinary herd health advisory services, lack of farmers' compliance to veterinary recommendations, public health interests, personal beliefs regarding the veterinary contribution to antimicrobial resistance and major economic powers are all influential determinants in antimicrobial prescribing behaviour of farm animal veterinarians. Interventions to change prescribing behaviour of farm animal veterinarians could address attitudes and advisory skills of veterinarians, as well as provide tools to deal with (perceived) pressure from farmers and advisors to prescribe antimicrobials. Additional (policy) measures could probably support farm animal veterinarians in acting as a more independent animal health consultant. © 2014 Blackwell

Understanding veterinary leadership in practice.

The Vet Futures Report has identified 'exceptional leadership' as a key ambition for the long-term sustainability of the industry. This research investigates what it is like to be a veterinary surgeon in an in-practice leadership position, applying the qualitative methodology of interpretative phenomenological analysis. Through the researchers' interpretation of the seven participants' stories of their leadership experiences, the study advances understanding of the work environment, underlying motivations and the perceived responsibilities of veterinary leaders. Findings suggest, for many, a struggle in transition to leader positions, improving with time. The increase in pace of work is relayed by participants, with an ongoing, and unchallenged, work-life imbalance. The vets involved are highly motivated, driven by enjoyment of their jobs, a desire for self-determination and a need to make a difference. Relationships form the core of the perceived responsibilities, and yet are identified as the greatest day-to-day challenge of leadership. This study offers a valuable insight for veterinary surgeons, suggesting the industry could benefit from pausing and reflecting on behaviours. With a greater understanding of the complexity of leadership and followership, progress can be made to enact positive changes for the future. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

Clinical and molecular epidemiology of veterinary blastomycosis in Wisconsin.

PubMed

Anderson, Jennifer L; Sloss, Brian L; Meece, Jennifer K

2013-04-22

Several studies have shown that Blastomyces dermatitidis, the etiologic agent of blastomycosis, is a genetically diverse pathogen. Blastomycosis is a significant health issue in humans and other mammals. Veterinary and human isolates matched with epidemiological case data from the same geographic area and time period were used to determine: (i) if differences in genetic diversity and structure exist between clinical veterinary and human isolates of B. dermatitidis and (ii) if comparable epidemiologic features differ among veterinary and human blastomycosis cases. Genetic typing of 301 clinical B. dermatitidis isolates produced 196 haplotypes (59 unique to veterinary isolates, 134 unique to human isolates, and 3 shared between canine and human isolates). Private allelic richness was higher in veterinary (median 2.27) compared to human isolates (median 1.14) (p = 0.005). Concordant with previous studies, two distinct genetic groups were identified among all isolates. Genetic group assignment was different between human and veterinary isolates (p < 0.001), with more veterinary isolates assigned to Group 2. The mean age of dogs diagnosed with blastomycosis was 6 years. Thirty cases were in male dogs (52%) and 24 were females (41%). The breed of dog was able to be retrieved in 38 of 58 cases with 19 (50%) being sporting breeds. Three of four felines infected with blastomycosis were domestic shorthair males between ages 6-12, and presented with disseminated disease. The other was a lynx with pulmonary disease. The equine isolate was from an 11-year-old male Halflinger with disseminated disease. Disseminated disease was reported more often in veterinary (62%) than human cases (19%) (p < 0.001). Isolates from all hosts clustered largely into previously identified genetic groups, with 3 haplotypes being shared between human and canine isolates confirming that B. dermatitidis isolates capable of infecting both species occur in nature.

We studied changes in mean gestational sac diameter (MSD) and embryonic crown-rump length (CRL) in intrauterine pregnancies of uncertain viability (IPUVs). We aimed to establish cut-off values for MSD and CRL growth that could be definitively associated with either viability or miscarriage, and to establish the relationship between growth in MSD and appearance of embryonic structures in the gestational sac. One thousand and sixty consecutive IPUVs were recruited prospectively from four London University hospitals: 462 with no yolk sac or embryo, 419 with a yolk sac but no embryo, and 179 with an embryo but no heartbeat visible. IPUV was defined as an empty gestational sac with or without a yolk sac but no embryo seen with MSD < 20 or < 30 mm (depending on center) or an embryo with no heartbeat and CRL < 6 mm or < 8 mm (depending on center). Scans were repeated 7-14 days later. The endpoint was viability at first-trimester screening ultrasonography between 11 and 14 weeks. Change in MSD and CRL between the first and second scans of each pregnancy was compared with respect to viability and appearance of embryonic structures using the two-sample t-test. The study included 359 pregnancies in which a gestational sac with or without embryo was identified at the follow-up scan 7-14 days later. Of these, 192 were viable and 167 non-viable at the 11-14-week scan. MSD growth was significantly higher in viable than non-viable pregnancies (mean 1.003 vs. 0.503 mm/day; P < 0.001, 95% CI of difference 0.403-0.596).

SacIp dysfunction results in bypass of the requirement for phosphatidylinositol transfer protein (Sec14p) function in yeast Golgi processes. This effect is accompanied by alterations in inositol phospholipid metabolism and inositol auxotrophy. Elucidation of how sac1 mutants effect “bypass Sec14p” will provide insights into Sec14p function in vivo. We now report that, in addition to a dramatic accumulation of phosphatidylinositol-4-phosphate, sac1 mutants also exhibit a specific acceleration of phosphatidylcholine biosynthesis via the CDP-choline pathway. This phosphatidylcholine metabolic phenotype is sensitive to the two physiological challenges that abolish bypass Sec14p in sac1 strains; i.e. phospholipase D inactivation and expression of bacterial diacylglycerol (DAG) kinase. Moreover, we demonstrate that accumulation of phosphatidylinositol-4-phosphate in sac1 mutants is insufficient to effect bypass Sec14p. These data support a model in which phospholipase D activity contributes to generation of DAG that, in turn, effects bypass Sec14p. A significant fate for this DAG is consumption by the CDP-choline pathway. Finally, we determine that CDP-choline pathway activity contributes to the inositol auxotrophy of sac1 strains in a novel manner that does not involve obvious defects in transcriptional expression of the INO1 gene.

Nicol, J

1983-03-01

Questionnaires were sent out to 68 registered female veterinary surgeons in South Africa to obtain career information essential to vocational guidance. The 46 respondents represent 51,7% of the 89 female BVSc graduates up to 1981; their average age was 33,3 years, 63% were married, 30,4% were from the Pretoria area, 60,9% were living in the Transvaal, 52,2% had had 6 and more years of veterinary experience. All the comparisons done indicated that the response group was representative of the women who had obtained the BVSc degree from the University of Pretoria. Some of the more important findings were the following: No less than 97,8% of the response group are at present actively engaged in veterinary work--73,9% on a full-time basis. Asked what they would choose now, 84,8% of the respondents declared that they would choose veterinary science once again; 67,4% would like to see their daughters enter the profession. The most important reason for this positive attraction towards veterinary practice was given as "job satisfaction experienced". Respondents indicated the things that they liked about veterinary practice: factors intrinsic to the job like surgery, pathology and research topped the list followed by the opportunity to work with and help animals and also the variety experienced in their work. The most important grievances were firstly the general attitude and actions of the public--callousness of animal-owners and inconsiderate behaviour towards practitioners. Long and irregular hours, administrative red tape and insufficient technical help were also complaints.(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of the study was to observe changes in endolymphatic hydrops by using intratympanic injection of gadolinium and magnetic resonance imaging (MRI) before and after endolymphatic sac surgery in patients with unilateral Meniere's disease. Thirteen patients with unilateral Meniere's disease undergoing endolymphatic sac surgery were retrospectively and prospectively analyzed. Three-dimensional fluid-attenuated inversion recovery or three-dimensional real inversion recovery MRI was performed 24 h after an intratympanic injection of gadolinium to grade the presence of endolymphatic hydrops. Among the 13 patients with hydrops confirmed by preoperative MRI, vestibular hydrops had no significant change in all patients; cochlear hydrops became negative in 2 patients, and remained unchanged in the other 11 patients after surgery. Definite vertigo attacks were substantially controlled in one patient and completely controlled in 12 patients during a follow-up period of 8-34 months after surgery. The hearing levels were improved in 3 patients, remained unchanged in 7 patients, and decreased in 3 patients. In conclusion, endolymphatic sac surgery does not always alleviate endolymphatic hydrops in patients with Meniere's disease. Relief from vertigo cannot always be attributed to the remission of hydrops. A change in hearing levels cannot be explained by hydrops status alone.

Antibiotic prophylaxis in veterinary cancer chemotherapy: A review and recommendations.

PubMed

Bisson, J L; Argyle, D J; Argyle, S A

2018-06-12

Bacterial infection following cancer chemotherapy-induced neutropenia is a serious cause of morbidity and mortality in human and veterinary patients. Antimicrobial prophylaxis is controversial in the human oncology field, as any decreased incidence in bacterial infections is countered by patient adverse effects and increased antimicrobial resistance. Comprehensive guidelines exist to aid human oncologists in prescribing antimicrobial prophylaxis but similar recommendations are not available in veterinary literature. As the veterinarian's role in antimicrobial stewardship is increasingly emphasized, it is vital that veterinary oncologists implement appropriate antimicrobial use. By considering the available human and veterinary literature we present an overview of current clinical practices and are able to suggest recommendations for prophylactic antimicrobial use in veterinary cancer chemotherapy patients. © 2018 The Authors.

Oncology pain in veterinary patients.

Looney, Andrea

2010-02-01

Cancer, cancer pain, and the undertreatment of cancer pain are epidemic in both the human and veterinary medical field. Concerns over recognition, assessment, and treatment of oncologic pain in our veterinary patients are multiplied when one realizes the interaction of the primary tumor, the pain itself, and even cancer treatments with fatigue, disability, dyspnea, weakness, impaired gastrointestinal motility, cognition, and urinary/defecation issues. The patient's overall health status, as well as owner psychological and spiritual distress, plays a large part in quality-of-life decisions. We will discuss classification and assessment of cancer pain, quality-of-life issues, and therapies for managing cancer pain, including pharmacologic, nonpharmacologic, and interventional techniques. The goal will be establishment of a new oncologic treatment pyramid or scale for veterinary patients, one that will guide clinicians mechanistically into thinking through the anamnesis, physical examination, and assessment of the whole patient, and on toward diagnostics and treatments available for companion animals with cancer.

DNA vaccines in veterinary use

PubMed Central

Redding, Laurel; Werner, David B

2015-01-01

DNA vaccines represent a new frontier in vaccine technology. One important application of this technology is in the veterinary arena. DNA vaccines have already gained a foothold in certain fields of veterinary medicine. However, several important questions must be addressed when developing DNA vaccines for animals, including whether or not the vaccine is efficacious and cost effective compared with currently available options. Another important question to consider is how to apply this developing technology in a wide range of different situations, from the domestic pet to individual fish in fisheries with several thousand animals, to wildlife programs for disease control. In some cases, DNA vaccines represent an interesting option for vaccination, while in others, currently available options are sufficient. This review will examine a number of diseases of veterinary importance and the progress being made in DNA vaccine technology relevant to these diseases, and we compare these with the conventional treatment options available.

2003-01-01

The Australian Pesticides and Veterinary Medicines Authority (APVMA)* registers veterinary antibiotic products before they can be supplied, distributed or sold in Australia. Extensive scientific assessment on all new veterinary antibiotic products is undertaken for the APVMA by experts in other government agencies including the Therapeutic Goods Administration (toxicology), the National Occupational Health and Safety Commission (occupational health and safety), Environment Australia (environmental hazards) and state departments of agriculture or primary industry (efficacy and safety) as well as APVMA assessments on food residues, trade and manufacturing. The National Health and Medical Research Council Expert Advisory Group on Antimicrobial Resistance provides advice to the APVMA on the potential transfer of antibiotic resistance from the use of antibiotics in animals to humans, and the impact transfer may have on public health. Food Standards Australia New Zealand (previously Australia New Zealand Food Authority) set maximum residue levels for human foods. The APVMA monitors registered product use through compliance activities and an adverse experience reporting program, and reviews registered products as necessary. The import, manufacture, supply and use of veterinary antibiotics are regulated by Commonwealth and State governments in Australia.

Distal regeneration involves the age dependent activity of branchial sac stem cells in the ascidian Ciona intestinalis

PubMed Central

2014-01-01

Abstract Tunicates have high capacities for regeneration but the underlying mechanisms and their relationship to life cycle progression are not well understood. Here we investigate the regeneration of distal structures in the ascidian tunicate Ciona intestinalis. Analysis of regenerative potential along the proximal−distal body axis indicated that distal organs, such as the siphons, their pigmented sensory organs, and the neural complex, could only be replaced from body fragments containing the branchial sac. Distal regeneration involves the formation of a blastema composed of cells that undergo cell proliferation prior to differentiation and cells that differentiate without cell proliferation. Both cell types originate in the branchial sac and appear in the blastema at different times after distal injury. Whereas the branchial sac stem cells are present in young animals, they are depleted in old animals that have lost their regeneration capacity. Thus Ciona adults contain a population of age‐related stem cells located in the branchial sac that are a source of precursors for distal body regeneration. PMID:25893097

Reflections on the future of veterinary medical education.

Prasse, Keith W

2009-01-01

Dr. Keith Prasse is a very distinguished leader in veterinary education. He started his career achieving his BS and DVM degrees from Iowa State University (ISU). He returned to ISU after a brief period in private practice in Illinois. His well-recognized career in veterinary pathology began with his MS and PhD degrees, followed by a five-year period of teaching at ISU. Dr. Prasse joined the faculty of the University of Georgia in 1972, and thus began a long-term partnership with Dr. Bob Duncan that is arguably the foundation of veterinary clinical pathology. The textbook they authored, Veterinary Laboratory Medicine: Clinical Pathology, or "Duncan and Prasse" as it is known, remains the standard today, with later participation from Dr. Ed Mahaffey and most recently Dr. Ken Latimer. Dr. Prasse has mentored numerous graduate students and received many awards over his 23-year career in teaching, including the Norden Distinguished Teaching award twice, once at ISU and once at Georgia. His leadership as President of the American College of Veterinary Pathologists was greatly acknowledged and appreciated. Dr. Prasse's administrative service at the University of Georgia spanned 14 years, first as Associate Dean for Public Service and Outreach and later as Dean for eight years, during which time he served as President of the Association of American Veterinary Medical Colleges (AAVMC). The growth of the College of Veterinary Medicine under Dean Prasse's visionary leadership was extraordinary. He led through difficult economic and political times, yet the college and its community continued to prosper. His legacy at the University of Georgia is indelible and perpetual. His outstanding leadership of the college was recognized by the Georgia Veterinary Medical Association in 2004, when he was given the Georgia Veterinarian of the Year award. Since his retirement from Georgia, Dr. Prasse has contributed greatly to the profession and to the AAVMC by leading the Foresight project

Lessons of history in veterinary medicine.

PubMed

Smith, Donald F

2013-01-01

The future of veterinary medicine is best understood in the context of history. What began as a profession rooted in urban centers in proximity to horses, physicians, and medical schools, was transformed into a land grant-based agricultural profession with the arrival of the internal combustion engine in the early twentieth century. Most of the United States' current veterinary colleges are still located in towns or small cities in the middle section of the country, outside the largest metropolitan areas where most veterinarians practice companion-animal medicine. Throughout veterinarian history, substantial numbers of US students have been educated in foreign colleges and this continues today, creating an even greater geographic imbalance between the veterinary educational process and US population centers and major medical schools. Three themes deserve special attention as we celebrate the profession's 150th anniversary. We must first move beyond the land-grant culture and develop a more geographically balanced approach to establishing new veterinary colleges that are also in closer association with schools of medicine and public health. We must also facilitate more opportunities for women leadership in organized veterinary medicine, in practice ownership, in academia, and in the corporate structures that educate, hire, and interface with veterinarians. Finally, we need to expand our understanding of One Health to include the concept of zooeyia (the role of animals in promoting human health), as well as continue to emphasize veterinarians' special roles in the control and management of zoonotic diseases and in advancing comparative medicine in the age of the genome.

Veterinary Fusarioses within the United States

Sutton, Deanna A.; Wiederhold, Nathan; Robert, Vincent A. R. G.; Crous, Pedro W.; Geiser, David M.

2016-01-01

Multilocus DNA sequence data were used to assess the genetic diversity and evolutionary relationships of 67 Fusarium strains from veterinary sources, most of which were from the United States. Molecular phylogenetic analyses revealed that the strains comprised 23 phylogenetically distinct species, all but two of which were previously known to infect humans, distributed among eight species complexes. The majority of the veterinary isolates (47/67 = 70.1%) were nested within the Fusarium solani species complex (FSSC), and these included 8 phylospecies and 33 unique 3-locus sequence types (STs). Three of the FSSC species (Fusarium falciforme, Fusarium keratoplasticum, and Fusarium sp. FSSC 12) accounted for four-fifths of the veterinary strains (38/47) and STs (27/33) within this clade. Most of the F. falciforme strains (12/15) were recovered from equine keratitis infections; however, strains of F. keratoplasticum and Fusarium sp. FSSC 12 were mostly (25/27) isolated from marine vertebrates and invertebrates. Our sampling suggests that the Fusarium incarnatum-equiseti species complex (FIESC), with eight mycoses-associated species, may represent the second most important clade of veterinary relevance within Fusarium. Six of the multilocus STs within the FSSC (3+4-eee, 1-b, 12-a, 12-b, 12-f, and 12-h) and one each within the FIESC (1-a) and the Fusarium oxysporum species complex (ST-33) were widespread geographically, including three STs with transoceanic disjunctions. In conclusion, fusaria associated with veterinary mycoses are phylogenetically diverse and typically can only be identified to the species level using DNA sequence data from portions of one or more informative genes.

Dinkelman, Andrea L; Viera, Ann R; Bickett-Weddle, Danelle A

2011-01-01

This qualitative study seeks to determine the nature of the instruction librarians provide to veterinary medical students at all 28 United States veterinary colleges. A secondary goal of the study was to determine in what ways and to what extent librarians participated in other instructional activities at their colleges. Over half of the librarians formally taught in one or more courses, predominantly in the first two years of the veterinary curriculum. One presentation per course was most common. Over half of the librarians interviewed stated that evidence-based veterinary medicine was taught at their colleges, and about half of these librarians collaborated with veterinary faculty in this instruction. Many librarians participated in orientation for first-year veterinary students. The librarians also taught instructional sessions for residents, interns, faculty, graduate students, and practicing veterinarians. This study found that librarians teach information literacy skills both formally and informally, but, in general, instruction by librarians was not well integrated into the curriculum. This study advances several recommendations to help veterinary students develop information literacy skills. These include: encourage veterinary faculty and administrators to collaborate more closely with librarians, incorporate a broader array of information literacy skills into assignments, and add a literature evaluation course to the curriculum.

Comparing Tolerance of Ambiguity in Veterinary and Medical Students.

PubMed

Hancock, Jason; Hammond, Jennifer A; Roberts, Martin; Mattick, Karen

Current guidelines suggest that educators in both medical and veterinary professions should do more to ensure that students can tolerate ambiguity. Designing curricula to achieve this requires the ability to measure and understand differences in ambiguity tolerance among and within professional groups. Although scales have been developed to measure tolerance of ambiguity in both medical and veterinary professions, no comparative studies have been reported. We compared the tolerance of ambiguity of medical and veterinary students, hypothesizing that veterinary students would have higher tolerance of ambiguity, given the greater patient diversity and less well-established evidence base underpinning practice. We conducted a secondary analysis of questionnaire data from first- to fourth-year medical and veterinary students. Tolerance of ambiguity scores were calculated and compared using the TAMSAD scale (29 items validated for the medical student population), the TAVS scale (27 items validated for the veterinary student population), and a scale comprising the 22 items common to both scales. Using the TAMSAD and TAVS scales, medical students had a significantly higher mean tolerance of ambiguity score than veterinary students (56.1 vs. 54.1, p<.001 and 60.4 vs. 58.5, p=.002, respectively) but no difference was seen when only the 22 shared items were compared (56.1 vs. 57.2, p=.513). The results do not support our hypothesis and highlight that different findings can result when different tools are used. Medical students may have slightly higher tolerance of ambiguity than veterinary students, although this depends on the scale used.

Lion anal sac secretion were found to be richer in lipids and to contain more complex less uniform mixtures of lower moleculas weight lipids then the anal sac of the red fox. In the lion, homologous series of 1-alkylglycerols and 2-hydroxy-fatty acids were identified. Phenylacetic, 3-phenylpropionic, and related hydroxylated acids were also observed. Gas-liquid chromatography profiles of fox anal sac secretion lower molecular weight lipids were found to be less variable in their major constituents and to be dominated by relatively few large peaks, mainly (derivatized) fatty acids. Indole was also identified. Free cholesterol, and occasionally, stanols were observed in fox and lion secretions. In the red fox, total cholesterol levels averaged 0.93 mg/g (% free, 56.4), n = 5. Findings are discussed in relation to histological and anatomical similarities and differences between the anal sacs of the lion and the fox and in the context of the role of these secretions in chemical communication.

Exposure assessment of veterinary medicines in aquatic systems

The release of veterinary medicines into the aquatic environment may occur through direct or indirect pathways. An example of direct release is the use of medicines in aquaculture (Armstrong et al. 2005; Davies et al. 1998), where chemicals used to treat fish are added directly to water. Indirect releases, in which medicines make their way to water through transport from other matrices, include the application of animal manure to land or direct excretion of residues onto pasture land, from which the therapeutic chemicals may be transported into the aquatic environment (Jørgensen and Halling-Sørensen 2000; Boxall et al. 2003, 2004). Veterinary medicines used to treat companion animals may also be transported into the aquatic environment through disposal of unused medicines, veterinary waste, or animal carcasses (Daughton and Ternes 1999, Boxall et al. 2004). The potential for a veterinary medicine to be released to the aquatic environment will be determined by several different criteria, including the method of treatment, agriculture or aquaculture practices, environmental conditions, and the properties of the veterinary medicine.

A total of 292 adverse reactions to veterinary medicinal products were reported during the year 2015. This represents an increase of 9% compared to the previous year (268 reports). Similar to previous years, most of the reactions reported were linked to the use of antiparasitics (55.1%), non-steroidal anti-inflammatory products (8.9%) or antiinfectives (9.3%). The affected animal species were primarily dogs (198 reports) and cats (42 reports), followed by cattle (31 reports) and horses (8 reports). Additional 42 reports were provided within the frame of consultations with Tox Info Suisse in Zürich and involved mainly the excessive intake of flavored tablets. Eight signals were identified from the reports received or the periodic safety update reports. They resulted in revisions of the product information in sections addressing contraindications, adverse reactions or withdrawal times.

Internationally, forensic medicine and pathology are increasingly recognized as an important aspect of work done by veterinary clinicians and veterinary pathologists. In this article, a forensic veterinary clinician, a forensic veterinary pathologist in private practice, and a forensic veterinary pathologist at a veterinary school discuss the interactions among veterinary clinicians, veterinary pathologists, and law enforcement agencies and how future interactions can be improved. The focus is on the United Kingdom, but many of the principles, challenges, and suggestions are applicable to other jurisdictions. Clinicians and pathologists require forensic training to enable them to apply their veterinary knowledge to suspected cases of animal abuse and to subsequently present their findings and conclusions to a court of law in a concise, professional, and unbiased manner, and some opportunities for such advanced training in the United Kingdom are indicated. It is important that forensic veterinary clinicians and pathologists interact in an unbiased and collegial manner to answer the questions posed by courts of law. Opportunities for improved training, communication, and interaction among forensic veterinarians, forensic scientists, and law enforcement are discussed. © The Author(s) 2016.

Deficiencies of effectiveness of intervention studies in veterinary medicine: a cross-sectional survey of ten leading veterinary and medical journals

2016-01-01

The validity of studies that assess the effectiveness of an intervention (EoI) depends on variables such as the type of study design, the quality of their methodology, and the participants enrolled. Five leading veterinary journals and 5 leading human medical journals were hand-searched for EoI studies for the year 2013. We assessed (1) the prevalence of randomized controlled trials (RCTs) among EoI studies, (2) the type of participants enrolled, and (3) the methodological quality of the selected studies. Of 1707 eligible articles, 590 were EoI articles and 435 RCTs. Random allocation to the intervention was performed in 52% (114/219; 95%CI:45.2–58.8%) of veterinary EoI articles, against 87% (321/371; 82.5–89.7%) of human EoI articles (adjusted OR:9.2; 3.4–24.8). Veterinary RCTs were smaller (median: 26 animals versus 465 humans) and less likely to enroll real patients, compared with human RCTs (OR:331; 45–2441). Only 2% of the veterinary RCTs, versus 77% of the human RCTs, reported power calculations, primary outcomes, random sequence generation, allocation concealment and estimation methods. Currently, internal and external validity of veterinary EoI studies is limited compared to human medical ones. To address these issues, veterinary interventional research needs to improve its methodology, increase the number of published RCTs and enroll real clinical patients. PMID:26835187

2010-07-01

To explore perceptions of faculty educators regarding the importance of nontechnical competencies in veterinary graduates and the placement of nontechnical competency development in veterinary education. Survey. All faculty members at 5 North American veterinary medical institutions. Participants rated the importance of 14 nontechnical competencies and indicated in which phase or phases of veterinary education such competencies should be developed (ie, curriculum placement). Differences in mean ratings were statistically evaluated, as were associations between ratings or curriculum placement and respondent institution, gender, experience, and discipline. Mean ratings of importance were above neutral for all competencies and were highest for ethical, critical thinking, and interpersonal and intrapersonal competencies; development of these competencies was favored in preveterinary and veterinary training. Ratings were lower for management and business competencies; development of these and other competencies was placed primarily in the clinical phase of the veterinary curriculum. Basic science, nonveterinarian, and junior faculty appeared to more strongly appreciate the importance of nontechnical skills, whereas large animal and midcareer faculty reported a more reserved degree of support. Female faculty were more likely to place nontechnical competency development throughout the educational process. Participants agreed nontechnical competencies are important for veterinary graduates; however, faculty perceptions differed from previously published findings regarding the relative importance of business and management skills. Those involved in faculty hiring, faculty development, and curricular planning should also be aware of disciplinary and career stage differences affecting faculty perspectives.

Cell-Based Veterinary Pharmaceuticals - Basic Legal Parameters Set by the Veterinary Pharmaceutical Law and the Genetic Engineering Law of the European Union.

PubMed

Faltus, Timo; Brehm, Walter

2016-01-01

Cell-based therapies have been in use in veterinary medicine for years. However, the legal requirement of manufacturing, placing on the market and use of cell-based veterinary pharmaceuticals are not as well developed as the respective requirements of chemical pharmaceuticals. Cell-based veterinary pharmaceuticals are medicinal products in the sense of the pharmaceutical law of the European Union (EU). For that reason, such medicinal products principally require official approval for their manufacture and an official marketing authorization for their placement on the market before being used by the veterinarian. The manufacture, placing on the market, and use of cell-based veterinary pharmaceuticals without manufacturing approval and marketing authorization is permitted only in certain exceptional cases determined by EU and individual Member State law. Violations of this requirement may have consequences for the respective veterinarian under criminal law and under the code of professional conduct in the respective Member State. The regular use of cell-based veterinary pharmaceuticals within the scope of a therapeutic emergency as well as the import of such veterinary pharmaceuticals from non-European countries for use in the EU are currently out of the question in the EU because of a lack of legal bases. Here, we review the general legal requirement of manufacturing, placing on the market, and use of cell-based veterinary pharmaceuticals within the EU and point out different implementations of EU law within the different Member States.

The Student Actions Coding Sheet (SACS): An instrument for illuminating the shifts toward student-centered science classrooms

Erdogan, Ibrahim; Campbell, Todd; Hashidah Abd-Hamid, Nor

2011-07-01

This study describes the development of an instrument to investigate the extent to which student-centered actions are occurring in science classrooms. The instrument was developed through the following five stages: (1) student action identification, (2) use of both national and international content experts to establish content validity, (3) refinement of the item pool based on reviewer comments, (4) pilot testing of the instrument, and (5) statistical reliability and item analysis leading to additional refinement and finalization of the instrument. In the field test, the instrument consisted of 26 items separated into four categories originally derived from student-centered instruction literature and used by the authors to sort student actions in previous research. The SACS was administered across 22 Grade 6-8 classrooms by 22 groups of observers, with a total of 67 SACS ratings completed. The finalized instrument was found to be internally consistent, with acceptable estimates from inter-rater intraclass correlation reliability coefficients at the p < 0.01 level. After the final stage of development, the SACS instrument consisted of 24 items separated into three categories, which aligned with the factor analysis clustering of the items. Additionally, concurrent validity of the SACS was established with the Reformed Teaching Observation Protocol. Based on the analyses completed, the SACS appears to be a useful instrument for inclusion in comprehensive assessment packages for illuminating the extent to which student-centered actions are occurring in science classrooms.

2010-12-01

The identification and early development of novel antimicrobial agents for use in veterinary medicine is subject to many of the same business and technical challenges as those found in antimicrobial agent use for human infectious disease. However, as awareness that some of the antimicrobial classes used in veterinary medicine are the same as used in human medicine, concern by multiple stakeholders has increased that this nonhuman use might be contributing to the problem of antimicrobial resistance to pathogens in humans, particularly with regard to food-borne diseases, such as salmonellosis and campylobacteriosis. Consequently, the interface between veterinary and human antibiotic use and resistance, especially with respect to human microbial food safety, has begun to redirect the industry pipeline of novel antimicrobial agents to be commercialized for use in veterinary medicine.

The history of the veterinary profession and education in Indonesia.

PubMed

Priosoeryanto, Bambang Pontjo; Arifiantini, Iis

2014-01-01

The beginning of the veterinary profession in Indonesia dates back to the middle of the 19th century. During the Dutch colonization period a development program for large ruminants was started by the 'Nederlandsch-Indië' government. In 1907 this government established a veterinary laboratory, planned by Dr. J.K.F. de Does. The laboratory was then merged with a veterinary training course for Indonesian (bumiputera) 'veterinarians' named 'Cursus tot Opleiding van Inlandsche Veeartsen'. In 1910 the name of the training course was changed to 'Inlandsche Veeartsenschool', and in 1914 the school was named 'Nederlandsch-Indische Veeartsenijschool' (NIVS). During the Japanese occupation (1942-1945) the veterinary school was named 'Bogor Semon Zui Gakko'. After the declaration of independence by Indonesia in August 1945, it became the High School of Veterinary Education. In 1946 the curriculum was extended from 4 to 5 years. Thereafter the school was closed and re-opened a few times due to the changing political circumstances. In 1947 the first Faculty of Veterinary Medicine ('Diergeneeskundige Faculteit') of the University of Indonesia was established in the former building of NIVS at Taman Kencana Campus in Bogor. Between 1948 and 1963, four more veterinary faculties were established in Indonesia: Gajah Mada, Syiahkuala, Airlangga and Udayana. The Indonesian Veterinary Medical Association (IVMA) was established on January 9, 1953. The membership now exceeds 20,000 veterinarians and the association has 15 special interest groups. Since 2008, five new faculties of veterinary medicine have been established, bringing the total to 10.

[Research reveals a market for a veterinary behaviour clinic].

Jonckheer-Sheehy, Valerie; Endenburg, Nienke

2009-11-01

An enquiry into the requirement of a university veterinary behaviour clinic in The Netherlands revealed that there is a clear call for such a service. The specific demands and wishes of first line practicing veterinarians and companion animal owners were investigated. The research revealed that veterinarians are regular confronted with behaviour problems in companion animals and that they are willing to refer these cases to the University. They also expressed their need for access to continuing professional development opportunities in the field of veterinary behavioural medicine (which is something that most veterinary behaviour clinics associated with veterinary faculties provide). The demand from companion animal owners was also examined. It can be concluded that a large number of them had animals with behaviour problems and that they were willing to seek veterinary advice on these matters. In response to the above mentioned demands the University of Utrecht will open a veterinary behaviour clinic, providing high quality service for animals, their owners and the referring veterinarians. This service will be based on sound scientific practice and delivered by both veterinarians specialised in this field and recognised animal behaviour therapists.

Expression of thyroid hormone regulator genes in the yolk sac membrane of the developing chicken embryo

Thyroid hormones (THs) are essential for the correct development of nearly every structure in the body from the very early stages of development, yet the embryonic thyroid gland is not functional at these stages. To clarify the roles of the egg yolk as a source of THs, the TH content in the yolk and the expression of TH regulator genes in the yolk sac membrane were evaluated throughout the 21-day incubation period of chicken embryos. The yolk TH content (22.3 ng triiodothyronine and 654.7 ng thyroxine per total yolk on day 4 of incubation) decreased almost linearly along with development. Real-time PCR revealed gene expression of transthyretin, a principal TH distributor in the chicken, and of a TH-inactivating iodothyronine deiodinase (DIO3), until the second week of incubation when the embryonic pituitary-thyroid axis is generally thought to start functioning. The TH-activating deiodinase (DIO2) and transmembrane transporter of thyroxine (SLCO1C1) genes were expressed in the last week of incubation, which coincided with a marked increase of circulating thyroxine and a reduction in the yolk sac weight. DIO1, which can remove iodine from inactive THs, was expressed throughout the incubation period. It is assumed that the chicken yolk sac inactivates THs contained abundantly in the yolk and supplies the hormones to the developing embryo in appropriate concentrations until the second week of incubation, while THs may be activated in the yolk sac membrane in the last week of incubation. Additionally, the yolk sac could serve as a source of iodine for the embryo. PMID:28652559

Evaluating veterinary practitioner perceptions of communication skills and training.

2017-03-25

A survey was conducted among veterinary practitioners in the UK and the USA in 2012/2013. Thematic analysis was used to identify underlying reasons behind answers to questions about the importance of communication skills and the desire to participate in postgraduate communication skills training. Lack of training among more experienced veterinary surgeons, incomplete preparation of younger practitioners and differences in ability to communicate all contribute to gaps in communication competency. Barriers to participating in further communication training include time, cost and doubts in the ability of training to provide value. To help enhance communication ability, communication skills should be assessed in veterinary school applicants, and communication skills training should be more thoroughly integrated into veterinary curricula. Continuing education/professional development in communication should be part of all postgraduate education and should be targeted to learning style preferences and communication needs and challenges through an entire career in practice.

Harrysson, Ola L. A.; Marcellin-Little, Denis J.; Horn, Timothy J.

2015-03-01

Veterinary medicine has undergone a rapid increase in specialization over the last three decades. Veterinarians now routinely perform joint replacement, neurosurgery, limb-sparing surgery, interventional radiology, radiation therapy, and other complex medical procedures. Many procedures involve advanced imaging and surgical planning. Evidence-based medicine has also become part of the modus operandi of veterinary clinicians. Modeling and additive manufacturing can provide individualized or customized therapeutic solutions to support the management of companion animals with complex medical problems. The use of metal additive manufacturing is increasing in veterinary orthopedic surgery. This review describes and discusses current and potential applications of metal additive manufacturing in veterinary orthopedic surgery.

Total laparorobotic repair of abdominal aortic aneurysm with sac exclusion obliteration and aortobifemoral bypass.

2009-01-01

A 65-year-old man with coronary artery disease, hypertension, and peripheral vascular disease was found to have an asymptomatic abdominal aortic aneurysm (AAA) of 5.5 cm on surveillance for his peripheral vascular disease. Cardiac stress testing demonstrated no evidence of myocardial ischemia, and he opted to undergo open repair of his aneurysm. Laparorobotic repair of the infrarenal AAA using the da Vinci robotic system was performed with an aortobifemoral bypass. We describe a novel technique for AAA exclusion using a cerclage method, which greatly facilitates repair of infrarenal AAAs using laparorobotic techniques. Laparorobotic repair of infrarenal AAA can be greatly facilitated by AAA sac exclusion and obliteration without the need to ligate all lumbar arteries or to open the aneurysm. This virtually avoids blood loss from the sac and minimizes the possibility for open conversion as a result of poor visualization. Minimally invasive aortic intervention for aneurysmal disease using laparascopic methods has been reported in the literature. Problems associated with this technique include a prolonged learning curve and difficulty completing intracorporeal anastomoses. Robotic surgery provides an advantage over laparoscopic surgery in its ability to provide greater degrees of freedom in a relatively small field of view along with superior high-definition, three-dimensional visualization. To date, there have been no known reports of using robotic surgery in the United States as a sole method for repair of AAA. We report our technique of combining robotic surgery with a novel procedure for sac exclusion and obliteration to successfully repair AAA without the need for opening the aneurysm sac and endoaneurysmorrhaphy.

Veterinary Fusarioses within the United States.

O'Donnell, Kerry; Sutton, Deanna A; Wiederhold, Nathan; Robert, Vincent A R G; Crous, Pedro W; Geiser, David M

2016-11-01

Multilocus DNA sequence data were used to assess the genetic diversity and evolutionary relationships of 67 Fusarium strains from veterinary sources, most of which were from the United States. Molecular phylogenetic analyses revealed that the strains comprised 23 phylogenetically distinct species, all but two of which were previously known to infect humans, distributed among eight species complexes. The majority of the veterinary isolates (47/67 = 70.1%) were nested within the Fusarium solani species complex (FSSC), and these included 8 phylospecies and 33 unique 3-locus sequence types (STs). Three of the FSSC species (Fusarium falciforme, Fusarium keratoplasticum, and Fusarium sp. FSSC 12) accounted for four-fifths of the veterinary strains (38/47) and STs (27/33) within this clade. Most of the F. falciforme strains (12/15) were recovered from equine keratitis infections; however, strains of F. keratoplasticum and Fusarium sp. FSSC 12 were mostly (25/27) isolated from marine vertebrates and invertebrates. Our sampling suggests that the Fusarium incarnatum-equiseti species complex (FIESC), with eight mycoses-associated species, may represent the second most important clade of veterinary relevance within Fusarium Six of the multilocus STs within the FSSC (3+4-eee, 1-b, 12-a, 12-b, 12-f, and 12-h) and one each within the FIESC (1-a) and the Fusarium oxysporum species complex (ST-33) were widespread geographically, including three STs with transoceanic disjunctions. In conclusion, fusaria associated with veterinary mycoses are phylogenetically diverse and typically can only be identified to the species level using DNA sequence data from portions of one or more informative genes.

Zoonotic disease risk perceptions in the British veterinary profession.

PubMed

Robin, Charlotte; Bettridge, Judy; McMaster, Fiona

2017-01-01

In human and veterinary medicine, reducing the risk of occupationally-acquired infections relies on effective infection prevention and control practices (IPCs). In veterinary medicine, zoonoses present a risk to practitioners, yet little is known about how these risks are understood and how this translates into health protective behaviour. This study aimed to explore risk perceptions within the British veterinary profession and identify motivators and barriers to compliance with IPCs. A cross-sectional study was conducted using veterinary practices registered with the Royal College of Veterinary Surgeons. Here we demonstrate that compliance with IPCs is influenced by more than just knowledge and experience, and understanding of risk is complex and multifactorial. Out of 252 respondents, the majority were not concerned about the risk of zoonoses (57.5%); however, a considerable proportion (34.9%) was. Overall, 44.0% of respondents reported contracting a confirmed or suspected zoonoses, most frequently dermatophytosis (58.6%). In veterinary professionals who had previous experience of managing zoonotic cases, time or financial constraints and a concern for adverse animal reactions were not perceived as barriers to use of personal protective equipment (PPE). For those working in large animal practice, the most significant motivator for using PPE was concerns over liability. When assessing responses to a range of different "infection control attitudes", veterinary nurses tended to have a more positive perspective, compared with veterinary surgeons. Our results demonstrate that IPCs are not always adhered to, and factors influencing motivators and barriers to compliance are not simply based on knowledge and experience. Educating veterinary professionals may help improve compliance to a certain extent, however increased knowledge does not necessarily equate to an increase in risk-mitigating behaviour. This highlights that the construction of risk is complex and

Macrofauna community inside and outside of the Darwin Mounds SAC, NE Atlantic

NASA Astrophysics Data System (ADS)

2012-11-01

Over the past two decades, growing concerns have been raised regarding the effects of towed fishing gears, such as trawls and dredges, on deep-sea biodiversity and ecosystem functioning. Trawling disturbs the benthic communities both physically and biologically, and can eliminate the most vulnerable organisms and modify habitat structure; chronically disturbed communities are often dominated by opportunistic species. The European Union is under obligation to designate a network of offshore Special Areas of Conservation (SACs) and Marine Protected Areas (MPAs) by the end of 2012 based on the perceived expectation that these networks will help protect marine biodiversity and that within these areas, faunal abundance and diversity will be higher than the surrounding fished areas. The Darwin Mounds, only discovered in 1998, are located in the Rockall Trough, NE Atlantic at a depth of ~ 1000 m. Deep-water trawling regularly took place in the region of the Darwin Mounds; however in 2004 the mounds were designated as the first offshore SAC in UK and the area is now closed to bottom trawling. As part of the HERMIONE programme the influence of human impact on the Oceans was one of the key themes and in June 2011, an investigation of the macrofaunal community structure at comparable sites both inside and outside of the Darwin Mound SAC was undertaken. Macrofaunal communities were found to differ significantly, with the difference mostly driven by changes in the abundance of polychaetes, crustaceans and nematodes whilst no significant differences were seen for the other phyla. Whereas overall macrofaunal abundance was higher outside the SAC compared to within, this pattern varies considerably between phyla. Diversity indices showed no significant differences between protected and unprotected sites. This could indicate that a few years of preservation are not enough time to determine a recovery by the macrofaunal community of cold-water ecosystems and that a continued

Veterinary medical manpower: supply-demand projections to 2020.

A supply projection model to estimate the number of veterinarians available through the year 2020 was developed. When projected available manpower was compared with the need for veterinary medical services, as estimated in a National Academy of Science study, a net shortage was indicated in each year between 1976 and 2020. The manpower supply available if 3 additional veterinary colleges were developed in the United States was also estimated. It was concluded that, even with the additional output of these colleges, the supply of veterinarians will not keep pace with future needs for veterinary services.

A large number of duplication monstrosities have been observed in cattle, sheep, pigs, horses, goats, cats and dogs, ever since the publication of the famous woodcut of a swine double monster by J. S. Brant in Basel in 1496, better known as the "wunderbare Sau von Landser im Elsass". Albrecht Dürer also made a woodcut of this double monster in front of the village Landser in 1496. A picture of a deer double monster was published in 1603 by Heinrich Ulrich in Germany. In the monograph De monstrorum causis, natura et differentiis ..., published by the Italian Fortunius Licetus in 1616 pictures of double monsters being half man half dog are found. These fantasy figures have been popular for a long time and were supposed to be really in existence. Apart from these fantasy figures many pictures are known from real veterinary double monsters. U. Aldrovandus described in 1642 in his Monstrorum historia, besides many fantasy figures, also real human and veterinary double monsters and he gave also good pictures of them. In the 19th century examples of veterinary duplication monstrosities were published by I. Geoffroy Saint-Hilaire (1832-37), E. F. Gurlt (1832), W. Vrolik (1840) and C. Taruffi (1881); they proposed also concepts concerning the etiology. In the second volume of his famous handbook of teratology (1907), E. Schwalbe described many veterinary double monsters and discussed the theories of the genesis of congenital malformations. Various theories concerning the genesis of double monsters have been given since Aristotle (384-322 B.C.). ...

Cell-Based Veterinary Pharmaceuticals – Basic Legal Parameters Set by the Veterinary Pharmaceutical Law and the Genetic Engineering Law of the European Union

PubMed Central

Faltus, Timo; Brehm, Walter

2016-01-01

Cell-based therapies have been in use in veterinary medicine for years. However, the legal requirement of manufacturing, placing on the market and use of cell-based veterinary pharmaceuticals are not as well developed as the respective requirements of chemical pharmaceuticals. Cell-based veterinary pharmaceuticals are medicinal products in the sense of the pharmaceutical law of the European Union (EU). For that reason, such medicinal products principally require official approval for their manufacture and an official marketing authorization for their placement on the market before being used by the veterinarian. The manufacture, placing on the market, and use of cell-based veterinary pharmaceuticals without manufacturing approval and marketing authorization is permitted only in certain exceptional cases determined by EU and individual Member State law. Violations of this requirement may have consequences for the respective veterinarian under criminal law and under the code of professional conduct in the respective Member State. The regular use of cell-based veterinary pharmaceuticals within the scope of a therapeutic emergency as well as the import of such veterinary pharmaceuticals from non-European countries for use in the EU are currently out of the question in the EU because of a lack of legal bases. Here, we review the general legal requirement of manufacturing, placing on the market, and use of cell-based veterinary pharmaceuticals within the EU and point out different implementations of EU law within the different Member States.

Allergic diseases in animals are increasingly gaining importance in veterinary practice and as research models. For intradermal testing and allergen immunotherapy, a good knowledge of relevant allergens for the individual species is of great importance. Currently, the knowledge about relevant veterinary allergens is based on sensitization rates identified by intradermal testing or serum testing for allergen-specific IgE; crude extracts are the basis for most evaluations. Only a few studies provide evidence about the molecular structure of (particularly) dust mite, insect and mould allergens in dogs and horses, respectively. In those species, some major allergens differ from those in humans. This position paper summarizes the current knowledge about relevant allergens in dogs, cats and horses. © 2015 The Authors Allergy Published by John Wiley & Sons Ltd.

Fine structures of the ejaculatory sac and sperm pump of the scorpionfly Panorpa liui Hua (Mecoptera: Panorpidae).

PubMed

Shen, Jian; Hua, Baozhen

2013-08-01

Male adults of Panorpidae possess a special sperm pump, through which the males transfer liquid sperm to the females. However, the structures of the sperm pump and the transfer mechanism have not been satisfactorily elucidated hitherto. In this paper the structures of the ejaculatory sac and sperm pump of the scorpionfly Panorpa liui Hua were investigated using light microscopy and scanning electron microscopy. The ejaculatory sac is located between the basal end of the paired vasa deferentia and the aedeagus, comprising a small anterior part and a large posterior part. The anterior part is simple and functions only as a channel for sperm transfer. The epithelial cells of the large posterior part likely have secretory functions. The sperm pump is formed by the posterior region of the ejaculatory sac and derivates of the genital field, which enclose the pumping chamber, a piston and the associated muscles. The orifice of the ejaculatory duct lies ventrad of the piston. The piston of the sperm pump is heavily sclerotized and controlled by two antagonistic muscle pairs. A pair of simple tubular accessory glands opens to the pumping chamber. Two well-developed sex pheromone glands are located on the ventral side of the ejaculatory sac, and are composed of two fan-shaped lamellae. The epithelium of the sex pheromone glands is single-layered, and forms densely filamentous processes. The ejaculation mechanism is briefly discussed based on the morphology of ejaculatory sac and sperm pump. Copyright © 2013 Elsevier Ltd. All rights reserved.

OBJECTIVE To identify the scope of occupational hazards encountered by veterinary personnel and compare hazard exposures between veterinarians and technicians working in small and large animal practices. DESIGN Cross-sectional survey. POPULATION Licensed veterinarians and veterinary staff in Minnesota. PROCEDURES A survey of Minnesota veterinary personnel was conducted between February 1 and December 1, 2012. Adult veterinary personnel working in clinical practice for > 12 months were eligible to participate. Information was collected on various workplace hazards as well as on workplace safety culture. RESULTS 831 eligible people responded, representing approximately 10% of Minnesota veterinary personnel. A greater proportion of veterinarians (93%; 368/394) reported having received preexposure rabies vaccinations than did veterinary technicians (54%; 198/365). During their career, 226 (27%) respondents had acquired at least 1 zoonotic infection and 636 (77%) had been injured by a needle or other sharps. Recapping of needles was reported by 87% of respondents; the most common reason reported by veterinarians (41%; 142/345) and veterinary technicians (71%; 238/333) was being trained to do so at school or work. Recent feelings of depression were reported by 204 (25%) respondents. A greater proportion of technicians (42%; 155/365) than veterinarians (21%; 81/394) indicated working in an environment in which employees experienced some form of workplace abuse. CONCLUSIONS AND CLINICAL RELEVANCE Veterinary personnel in Minnesota were exposed to several work-related hazards. Practice staff should assess workplace hazards, implement controls, and incorporate instruction on occupational health into employee training. PMID:26720089

Fecal sacs attract insects to the nest and provoke an activation of the immune system of nestlings.

2016-01-01

Nest sanitation is a widespread but rarely studied behavior in birds. The most common form of nest sanitation behavior, the removal of nestling feces, has focused the discussion about which selective pressures determine this behavior. The parasitism hypothesis, which states that nestling fecal sacs attract parasites that negatively affect breeding birds, was proposed 40 years ago and is frequently cited as a demonstrated fact. But, to our knowledge, there is no previous experimental test of this hypothesis. We carried out three different experiments to investigate the parasitism hypothesis. First, we used commercial McPhail traps to test for the potential attraction effect of nestling feces alone on flying insects. We found that traps with fecal sacs attracted significantly more flies (Order Diptera), but not ectoparasites, than the two control situations. Second, we used artificial blackbird (Turdus merula) nests to investigate the combined attraction effect of feces and nest materials on arthropods (not only flying insects). Flies, again, were the only group of arthropods significantly attracted by fecal sacs. We did not detect an effect on ectoparasites. Third, we used active blackbird nests to investigate the potential effect of nestling feces in ecto- and endoparasite loads in real nestlings. The presence of fecal sacs near blackbird nestlings did not increase the number of louse flies or chewing lice, and unexpectedly reduced the number of nests infested with mites. The endoparasite prevalence was also not affected. In contrast, feces provoked an activation of the immune system as the H/L ratio of nestlings living near excrements was significantly higher than those kept under the two control treatments. Surprisingly, our findings do not support the parasitism hypothesis, which suggests that parasites are not the main reason for fecal sac removal. In contrast, the attraction of flies to nestling feces, the elevation of the immune response of chicks, and the

The study also aimed to identify sociodemographic and course-related factors associated with increased financial stress. Students from seven Australian veterinary schools were surveyed using an online questionnaire. A total of 443 students participated (response rate 17%). Responses to survey items relating to finances, employment and course-related costs were compared with sociodemographic factors and prior research in the area of student financial stress. Respondents reported spending a median of A$300 per week on living costs and a median of A$2,000 per year on course-related expenses. Over half of respondents received the majority of their income from their parents or Youth Allowance (56%). A similar proportion (55%) reported that they needed to work to meet basic living expenses. Circumstances and sociodemographic factors linked to perceived financial stress included requiring additional finances to meet unexpected costs during the course; sourcing additional finances from external loans; an expected tuition debt at graduation over A$40,000; being 22 years or older; working more than 12 hours per week; living costs above A$300 per week; and being female. The costs involved in obtaining a veterinary education in Australia are high and over half of respondents are reliant on parental or Government income support. Respondents with certain sociodemographic profiles are more prone to financial stress. These findings may have implications for the psychological health, diversity and career plans of veterinary students in Australia. © 2017 Australian Veterinary Association.

The amendments introduced to the current Veterinary Licensing Ordinance (TAppV) by the Veterinary Licensing Regulation (TAppO) have brought a high degree of skills orientation to fill the gap between academic study and preparing for a wide range of professional skills. In order to improve the veterinary skills of students while conveying fundamental methods in a structured and reproducible way, the University of Veterinary Medicine Hannover, Foundation, has set up the first central veterinary skills lab in Germany. Practical training is provided by means of a three-tier delivery approach. This involves around 40 simulators on an area of approx. 800 m² under the guidance of 6-8 staff members, along with supplementary resources such as posters, text instructions and YouTube videos. Since it opened in March 2013, there have been 769 visits to the skills lab and 30,734 hits on YouTube. Initial results show that the skills lab helps to maintain student motivation by teaching them practical skills at an early stage of the basic study-based acquisition of knowledge, whilst reinforcing skills acquisition per se in competence-based teaching. It enables veterinary students to prepare for their first examinations and treatments of live patients in a manner compliant with animal welfare. PMID:24872855

Veterinary drugs in the environment and their toxicity to plants.

PubMed

Bártíková, Hana; Podlipná, Radka; Skálová, Lenka

2016-02-01

Veterinary drugs used for treatment and prevention of diseases in animals represent important source of environmental pollution due to intensive agri- and aquaculture production. The drugs can reach environment through the treatment processes, inappropriate disposal of used containers, unused medicine or livestock feed, and manufacturing processes. Wide scale of veterinary pharmaceuticals e.g. antibiotics, antiparasitic and antifungal drugs, hormones, anti-inflammatory drugs, anaesthetics, sedatives etc. enter the environment and may affect non-target organisms including plants. This review characterizes the commonly used drugs in veterinary practice, outlines their behaviour in the environment and summarizes available information about their toxic effect on plants. Significant influence of many antibiotics and hormones on plant developmental and physiological processes have been proved. However, potential phytotoxicity of other veterinary drugs has been studied rarely, although knowledge of phytotoxicity of veterinary drugs may help predict their influence on biodiversity and improve phytoremediation strategies. Moreover, additional topics such as long term effect of low doses of drugs and their metabolites, behaviour of mixture of veterinary drugs and other chemicals in ecosystems should be more thoroughly investigated to obtain complex information on the impact of veterinary drugs in the environment.

A Novel Technique to Detect Code for SAC-OCDMA System

NASA Astrophysics Data System (ADS)

Bharti, Manisha; Kumar, Manoj; Sharma, Ajay K.

2018-04-01

The main task of optical code division multiple access (OCDMA) system is the detection of code used by a user in presence of multiple access interference (MAI). In this paper, new method of detection known as XOR subtraction detection for spectral amplitude coding OCDMA (SAC-OCDMA) based on double weight codes has been proposed and presented. As MAI is the main source of performance deterioration in OCDMA system, therefore, SAC technique is used in this paper to eliminate the effect of MAI up to a large extent. A comparative analysis is then made between the proposed scheme and other conventional detection schemes used like complimentary subtraction detection, AND subtraction detection and NAND subtraction detection. The system performance is characterized by Q-factor, BER and received optical power (ROP) with respect to input laser power and fiber length. The theoretical and simulation investigations reveal that the proposed detection technique provides better quality factor, security and received power in comparison to other conventional techniques. The wide opening of eye in case of proposed technique also proves its robustness.

Veterinary practitioners have extensive knowledge of animal health from their day-to-day observations of clinical patients. There have been several recent initiatives to capture these data from electronic medical records for use in national surveillance systems and clinical research. In response, an approach to surveillance has been evolving that leverages existing computerized veterinary practice management systems to capture animal health data recorded by veterinarians. Work in the United Kingdom within the VetCompass program utilizes routinely recorded clinical data with the addition of further standardized fields. The current study describes a prototype system that was developed based on this approach. In a 4-week pilot study in New Zealand, clinical data on presentation reasons and diagnoses from a total of 344 patient consults were extracted from two veterinary clinics into a dedicated database and analyzed at the population level. New Zealand companion animal and equine veterinary practitioners were engaged to test the feasibility of this national practice-based health information and data system. Strategies to ensure continued engagement and submission of quality data by participating veterinarians were identified, as were important considerations for transitioning the pilot program to a sustainable large-scale and multi-species surveillance system that has the capacity to securely manage big data. The results further emphasized the need for a high degree of usability and smart interface design to make such a system work effectively in practice. The geospatial integration of data from multiple clinical practices into a common operating picture can be used to establish the baseline incidence of disease in New Zealand companion animal and equine populations, detect unusual trends that may indicate an emerging disease threat or welfare issue, improve the management of endemic and exotic infectious diseases, and support research activities.

Expression of PDGFR-β and Kit in canine anal sac apocrine gland adenocarcinoma using tissue immunohistochemistry.

PubMed

Brown, R J; Newman, S J; Durtschi, D C; Leblanc, A K

2012-03-01

Canine anal sac apocrine gland adenocarcinoma (ASAGAC) is an uncommon but highly invasive and metastatic malignancy. Toceranib phosphate (Palladia) is a receptor tyrosine kinase (RTK) inhibitor that targets several members of the split kinase RTK family. These membrane receptors are important for cell cycling, apoptosis and angiogenesis, all of which can contribute to carcinogenesis. The objective of this study was to evaluate archived, paraffin-embedded canine ASAGAC and normal canine anal sacs for immunohistochemical detection of Kit and platelet-derived growth factor receptor beta (PDGFR-β). Two of 77 neoplasms (2.6%) expressed Kit. Fifteen of the neoplasms (19.5%) were positive for PDGFR-β expression. None of the normal canine anal sac epithelium expressed Kit or PDGFR-β. Because of these results, further investigation should be considered to determine the role of RTKs in the clinical course and treatment of canine ASAGAC. © 2011 Blackwell Publishing Ltd.

Veterinary and Equine Science Students’ Interpretation of Horse Behaviour

2017-01-01

Simple summary We assessed first-year veterinary science and veterinary technology and undergraduate equine science students interpretation of expressive horse behaviours. Previous experience with horses appeared to influence the students’ perception of the horses’ behaviour. Qualitative assessments of horse behaviour may be a useful tool for assessing students’ knowledge of horse behaviour. Abstract Many veterinary and undergraduate equine science students have little previous horse handling experience and a poor understanding of horse behaviour; yet horses are one of the most unsafe animals with which veterinary students must work. It is essential for veterinary and equine students to learn how to interpret horse behaviour in order to understand demeanour and levels of arousal, and to optimise their own safety and the horses’ welfare. The study utilised a qualitative research approach to investigate veterinary science and veterinary technology and undergraduate equine science students’ interpretation of expressive behaviours shown by horses. The students (N = 127) were shown six short video clips and asked to select the most applicable terms, from a pre-determined list, to describe the behavioural expression of each individual horse. A wide variation of terms were selected by students and in some situations of distress, or situations that may be dangerous or lead to compromised welfare, apparently contradictory terms were also selected (happy or playful) by students with less experience with horses. Future studies should consider the use of Qualitative Behavioural Analysis (QBA) and free-choice profiling to investigate the range of terms used by students to describe the expressive demeanour and arousal levels of horses.

The objective of this study was to compare doctor-patient communications in clinical consultations via telemedicine technology to doctor-patient communications in face-to-face clinical consultations. Five doctors who had been practicing internal medicine for 8 to 18 years, and twenty patients were enrolled in this study; neither doctors nor patients had previous experience of telemedicine. The patients received both a telemedicine consultation and a face-to-face consultation. Three measures--video observation, medical record volume, and participants' satisfaction--were used for the assessment. It was found that the time spent on the telemedicine consultation was substantially longer than the time spent on the face-to-face consultation. No statistically significant differences were found in the number of either closed or open-ended questions asked by doctors between both types of consultation. Empathy-utterances, praise-utterances, and facilitation-utterances were, however, seen less in the telemedicine consultations than in the face-to-face consultations. The volume of the medical records was statistically smaller in the telemedicine consultations than in the face-to-face consultations. Patients were satisfied with the telemedicine consultation, but doctors were dissatisfied with it and felt hampered by the communication barriers. This study suggests that new training programs are needed for doctors to develop improved communication skills and the ability to express empathy in telemedicine consultations.

The role of veterinary epidemiology and veterinary services in complying with the World Trade Organization SPS agreement.

2005-02-01

The agreement on the application of sanitary and phytosanitary measures (SPS agreement) was one of the major products of the GATT's Uruguay round of multilateral trade negotiations, signed in Marrakesh on 15 April 1994. This agreement and others are part of the treaty that established the World Trade Organization (WTO). The WTO superseded the GATT as the umbrella organization for international trade (WTO, 1998a). The SPS agreement's main intent is to provide guidelines and provisions to member countries to facilitate trade while taking measures to protect human, animal or plant life or health. The agreement dictates that all sanitary measures must be scientifically based and not more restrictive than required to avoid the risk identified. The agreement recommends the use of international standards from the World Organization for Animal Health (OIE), Codex Alimentarius (CAC) and the International Plant Protection Convention (IPPC) as the basis for import requirements. If a country chooses to apply more restrictive measures than those in the international standards, it has to justify its position through a risk analysis, thus avoiding the use of sanitary and phytosanitary measures as unjustified barriers to trade. More than ever, veterinary services worldwide are faced with having to fulfill a crucial role in protecting their country's animal health status, provide sound surveillance information on the occurrence of diseases within their territories, and conduct scientifically valid risk analyses to establish justified import requirements. During the past two decades, most countries have experienced resource reduction in their veterinary services. The effect of these policies has been severe, in many cases leading to an inability of veterinary services to conduct their disease prevention and control duties. There is a clear inconsistency between the demands placed on veterinary services and the current level of funding and support they are receiving, particularly in

The effectiveness of marketing concepts in veterinary practices.

What makes pet owners chose one veterinary practice and not another? This survey was performed to gain insight into what factors influence new clients' choice of veterinary practice, and consequently the most effective way to promote veterinary practices. To this end, a questionnaire was completed by 129 pet owners who became new clients of one of eight selected veterinary practices in January 2005 or later. All selected practices are members of the Dierenartsen Dienstgroep Domstad, Utrecht, The Netherlands. This survey showed word-of-mouth referral to be the most effective way to increase a practice client base: 32.8% of all respondents first heard of their practice of choice through a fellow pet owner. Other pet owners first 'heard' of their practice by passing the practice (17.2%), seeing an advertisement in the Yellow Pages (14.1%), visiting the veterinary practice website (13.3%), and looking in the phone book (10.9%). These information sources should be considered for promotional activities. However this is not the case for advertisements in newspapers or magazines: none of the respondents became acquainted with the practice through these media. Respondents primarily based their choice on personnel and product (the total package of services and its quality) and less on location, but many prospective clients also based their choice on promotional activities and prices. Because pet owners apparently take so many aspects into consideration when choosing a veterinary practice, the marketing orientation (focusing on the client with her/his wishes and problems) is crucial.

Double sac sign and intradecidual sign in early pregnancy: interobserver reliability and frequency of occurrence.

PubMed

Doubilet, Peter M; Benson, Carol B

2013-07-01

To assess the interobserver agreement, frequency of occurrence, and prognostic importance of the double sac sign (DSS), intradecidual sign (IDS), and other sonographic findings in early intrauterine pregnancies. We retrospectively identified all sonograms obtained between January 1, 2006, and December 31, 2011, in which: (1) the scan demonstrated an intrauterine fluid collection without a yolk sac or embryo; (2) a follow-up scan confirmed an intrauterine pregnancy; and (3) the first-trimester outcome was known. Each coinvestigator characterized the 199 study sonograms as demonstrating or not demonstrating a DSS or an IDS, based on judgment about whether the scan met published criteria defining these signs. Interobserver agreement was poor for the DSS (κ= 0.24) and IDS (κ= 0.23). Scans frequently demonstrated neither sign: 150 cases (75.4%) if we considered a sign to be present when both investigators graded it as present and 69 cases (34.7%) using the looser criterion that either graded it as present. The presence of a DSS or an IDS was unrelated to the β-human chorionic gonadotropin (β-hCG) value (P > .05, t test, all comparisons). An inner echogenic ring was present in 158 cases (79.4%), and the decidua was brighter peripherally than centrally in 102 (51.3%). The first-trimester outcome was unrelated to the presence of a DSS or an IDS, presence of an inner echogenic ring, or decidual appearance (P > .05, χ(2), all comparisons). The sonographic appearance of early gestational sacs, before visualization of a yolk sac or embryo, is highly variable. The DSS and IDS are often absent; there is poor interobserver agreement regarding these signs; and the prognosis is unrelated to their presence or absence. A round or oval intrauterine fluid collection in a woman with positive β-hCG should be treated as a gestational sac until proven otherwise, regardless of whether it demonstrates a DSS or an IDS.

Comparison of anaesthesia 'Day 1 skills' expectations between veterinary anaesthetists and general practitioners.

Day One Skills (DOS) were introduced by the Royal College of Veterinary Surgeons (RCVS) in 2006 as a guideline for minimum skills required by a veterinary graduate. However, the RCVS anaesthesia DOS are broad and do not specify differences in skills required for different species. The aims of this study were: (1) to determine which anaesthesia skills were considered essential for day one practice by UK-based veterinary practitioners (GPs) and anaesthetists; and (2) to explore current opinions on veterinary undergraduate anaesthesia training. Questionnaires for veterinary GPs (QGPs) and veterinary anaesthetists (QVAs) were developed which asked general information on expectations of anaesthesia skills as well as specific expectations for the common veterinary species. Fifty-five UK-based members of the Association of Veterinary Anaesthetists responded, with a random sample of veterinary practices stratified by UK county generating 234 responses and a convenience sample targeted at more specialist veterinary specialities in the UK generating 161 responses. There was close overall agreement between the two groups of GPs and anaesthetists on essential anaesthesia DOS. However, expectations varied with species-greatest in cats and dogs, lowest in exotics. Many respondents commented that new veterinary graduates lack practical skills and should not be expected to be omnicompetent across all species. In conclusion, anaesthesia undergraduate training should prioritise essential practical DOS. British Veterinary Association.

Differential gene expression profiles in the venom gland/sac of Eumenes pomiformis (Hymenoptera: Eumenidae).

PubMed

Baek, Ji Hyeong; Lee, Si Hyeock

2010-06-01

To search for novel transcripts encoding biologically active venom components, a subtractive cDNA library specific to the venom gland and sac (gland/sac) of a solitary hunting wasp species, Eumenes pomiformis Fabricius (1781), was constructed by suppression subtractive hybridization. A total of 541 expressed sequence tags (ESTs) were clustered and assembled into 102 contigs (31 multiple sequences and 71 singletons). In total, 37 cDNAs were found in the library via BLASTx searching and manual annotation. Eight contigs (337 ESTs) encoding short venom peptides (10 to 16 amino acids) occupied 62% of the library. The deduced amino acid sequence (78 amino acids) of a novel venom peptide transcript shared sequence similarity with trypsin inhibitors and dendrotoxin-like venom peptides known to be K(+) channel blockers, implying that this novel peptide may play a role in the paralysis of prey. In addition to phospholipase A2 and hyaluronidase, which are known to be the main components of wasp venoms, several transcripts encoding enzymes, including three metallopeptidases and a decarboxylase likely involved in the processing and activation of venomous proteins, peptides, amines, and neurotransmitters, were also isolated from the library. The presence of a transcript encoding a putative insulin/insulin-like peptide binding protein suggests that solitary hunting wasps use their venom to control their prey, leading to larval growth cessation. The abundance of these venom components in the venom gland/sac and in the alimentary canal was confirmed by quantitative real-time PCR. Discovery of venom gland/sac-specific transcripts should promote further studies on biologically active components in the venom of solitary hunting wasps. Copyright 2010 Elsevier Ltd.

The women described in this paper were the early pioneers in veterinary medicine; they studied in some of the best veterinary colleges in the world at that time. They paved the way for other women who studied veterinary medicine in later years. According to Drum and Whitely,25 by 1936, there were only 30 female veterinarians in the United States; this was an era when admission to veterinary college for women was nearly impossible. In 1963, there were 277 female veterinarians in the United States, but by 1987 women made up 17% of the veterinary profession. The February 15, 2010 issue of the JAVMA reported that male enrollment in U.S. veterinary colleges decreased from 89% for the 1969-70 school year to 22.4% for 2008-09. During the same period female enrollment increased from 11.0% to 77.6%.

Clear cell carcinoma (CCC) of the ovary is uncommon. In young patients, this tumor may simulate a yolk sac tumor. In this case, the morphologic distinction between these tumors is often difficult but the immunohistochemical staining for CA125 and alpha foeto protein (AFP) and the response to chemotherapy are particularly helpful to resolve this problem of differential diagnosis. We report a case of a 17 year old patient who was operated for a tumor of the right ovary. The diagnosis of a yolk sac tumor was first suggested. However, because of the non response to chemotherapy, a second laparotomy was performed; the definitive pathologic examination concluded to the diagnosis of a CCC of the ovary. The young age and the immunohistochemical staining for AFP are unusual and misleading features for a CCC. Our objective about this particular case is to discuss the anatomoclinical aspects of the CCC of the ovary and to prove the role of immunohistochemistry in the differential diagnosis.

A recent survey of European Colleges (European College of Equine Internal Medicine [ECEIM] and European College of Veterinary Surgeons [ECVS]) revealed the different strategies implemented by, and some of the challenges facing, European clinicians presented with cases of post operative ileus (POI). It was concluded that further comparative analysis of opinions, canvassed from additional colleges of equine veterinary specialism worldwide, would provide valuable additional insight into current POI knowledge on a more global scale. To report and compare the current strategies favoured by American veterinary specialists when managing POI in horses that underwent emergency colic surgery. Cross-sectional survey. Electronic invitations were sent to 814 Large Animal specialists, including 3 colleges: the American College of Veterinary Internal Medicine (ACVIM), American College of Veterinary Surgeons (ACVS) and the American College of Veterinary Emergency and Critical Care (ACVECC). The response rate was 14% (115/814). The majority of respondents (68%) reported an estimated prevalence range of POI of 0-20%. The presence of reflux on nasogastric intubation was the main criterion used to define POI. A lesion involving the small intestine was considered the main risk factor for POI. Anti-inflammatory drugs, intravenous (i.v.) fluids and antimicrobial drugs were the primary strategies used when managing POI. Flunixin meglumine and i.v. lidocaine were the drugs most commonly used in the treatment of horses with POI. Supplementary management strategies targeted mainly the prevention of post operative adhesions, infection and inflammation. There is a lack of consensus on the clinical definition of POI. Prospective and objective clinical assessment of the effectiveness of the different strategies contained within this and the European survey is necessary in order to identify a standardised approach to the management of equine POI. © 2015 EVJ Ltd.

Improving Student Engagement in Veterinary Business StudiesIn a densely packed veterinary curriculum, students may find it particularly challenging to engage in the less overtly clinical subjects, yet pressure from industry and an increasingly competitive employment market necessitate improved veterinary student education in business and management skills. We describe a curriculum intervention (formative reflective assignment) that optimizes workplace learning opportunities and aims to provide better student scaffolding for their in-context business learning. Students were asked to analyze a business practice they experienced during a period of extra-mural studies (external work placement). Following return to the college, they were then instructed to discuss their findings in their study group, and produce a group reflection on their learning. To better understand student engagement in this area, we analyzed individual and group components of the assignment. Thematic analysis revealed evidence of various depths of student engagement, and provided indications of the behaviors they used when engaging at different levels. Interactive and social practices (discussing business strategies with veterinary employees and student peers) appeared to facilitate student engagement, assist the perception of relevance of these skills, and encourage integration with other curriculum elements such as communication skills and clinical problem solving.

Treatment with thiamine hydrochloride and astaxanthine for the prevention of yolk-sac mortality in Baltic salmon fry (M74 syndrome).

Two practical methods are reported for treating feral Baltic salmon with thiamine hydrochloride against M74 syndrome (abnormally high yolk-sac fry mortality of the Baltic salmon). Both bathing of the yolk-sac fry in thiamine hydrochloride (1000 mg l-1, 1 h) and a single intraperitoneal injection given to the female brood fish (100 mg kg-1 fish) during the summer 3 mo before stripping were shown to elevate the whole body total thiamine concentration in the fry. Both treatments were also shown to be effective in preventing mortality due to M74 syndrome. The effect of bathing the yolk-sac fry was shown to be dose-dependent. The results support the view that there is a causal relationship between the thiamine status of the yolk-sac fry and M74 mortality. An intraperitoneal injection of astaxanthine suspension administered to the female brood fish (11 mg kg-1 fish) in the summer 3 mo before stripping elevated the astaxanthine concentration in the eggs but did not affect mortality due to M74 syndrome. An interaction between astaxanthine and thiamine may occur in the developing embryo or yolk-sac fry, however. No association could be demonstrated between the various thiamine hydrochloride treatment practices and hepatic cytochrome P450 dependent 7-ethoxyresorufin-O-deethylase (EROD) activity in the yolk-sac fry. An injection of thiamine hydrochloride into the peritoneal cavity of wild Baltic salmon females could be used to raise thiamine concentrations in their offspring in the rivers. The effect on smolt production in Finnish Baltic salmon rivers needs to be investigated further, however.

Pharmaceutical residues may have serious impacts on nontarget biological organisms in aquatic ecosystems, and have therefore precipitated numerous investigations worldwide. Many pharmaceutical compounds available on the market need to be prioritized based on their potential ecological and human health risks in order to develop sound management decisions. We prioritized veterinary pharmaceuticals in Korea by their usage, potential to enter the environment, and toxicological hazard. Twenty compounds were identified in the top priority class, most of which were antibiotics. Among these compounds, 8 were identified as deserving more immediate attention: amoxicillin, enramycin, fenbendazole, florfenicol, ivermectin, oxytetracycline, tylosin, and virginiamycin. A limitation of this study is that we initially screened veterinary pharmaceuticals by sales tonnage for veterinary use only. However, this is the first attempt to prioritize veterinary pharmaceuticals in Korea, and it provides important concepts for developing environmental risk management plans for such contaminants in aquatic systems.

This special issue of Veterinary Immunology and Immunopathology summarizes the Proceedings of the 9th International Veterinary Immunology Symposium (9th IVIS) held August 2010, in Tokyo, Japan. Over 340 delegates from 30 countries discussed research progress analyzing the immune systems of numerous food animals and wildlife, probing basic immunity and the influence of stress, genetics, nutrition, endocrinology and reproduction. Major presentations addressed defense against pathogens and alternative control and prevention strategies including vaccines, adjuvants and novel biotherapeutics. A special Organisation for Economic Co-operation and Development (OECD) Co-operative Research Programme Sponsored Conference on "Vaccination and Diagnosis for Food Safety in Agriculture" highlighted the particular issue of "Immunology in Bovine Paratuberculosis". In April 2010 there was an outbreak of foot-and-mouth disease (FMD) in the southern part of Japan. This stimulated a special 9th IVIS session on FMD, sponsored by the World Organization for Animal Health (OIE) and the Ministry of Agriculture, Forestry and Fisheries (MAFF) of Japan, to discuss improvements of FMD vaccines, their use in FMD control, and risk assessment for decision management. The 9th IVIS was supported by the Veterinary Immunology Committee (VIC) of the International Union of Immunological Societies (IUIS) and included workshops for its MHC and Toolkit Committees. Finally VIC IUIS presented its 2010 Distinguished Service Award to Dr. Kazuya Yamanouchi for "outstanding contributions to the veterinary immunology community" and its 2010 Distinguished Veterinary Immunologist Award to Dr. Douglas F. Antczak for "outstanding research on equine immunology". Published by Elsevier B.V.

Owing to lack of governmental regulation of veterinary laboratory performance, veterinarians ideally should demonstrate a commitment to self-monitoring and regulation of laboratory performance from within the profession. In response to member concerns about quality management in veterinary laboratories, the American Society for Veterinary Clinical Pathology (ASVCP) formed a Quality Assurance and Laboratory Standards (QAS) committee in 1996. This committee recently published updated and peer-reviewed Quality Assurance Guidelines on the ASVCP website. The Quality Assurance Guidelines are intended for use by veterinary diagnostic laboratories and veterinary research laboratories that are not covered by the US Food and Drug Administration Good Laboratory Practice standards (Code of Federal Regulations Title 21, Chapter 58). The guidelines have been divided into 3 reports on 1) general analytic factors for veterinary laboratory performance and comparisons, 2) hematology and hemostasis, and 3) clinical chemistry, endocrine assessment, and urinalysis. This report documents recommendations for control of general analytical factors within veterinary clinical laboratories and is based on section 2.1 (Analytical Factors Important In Veterinary Clinical Pathology, General) of the newly revised ASVCP QAS Guidelines. These guidelines are not intended to be all-inclusive; rather, they provide minimum guidelines for quality assurance and quality control for veterinary laboratory testing. It is hoped that these guidelines will provide a basis for laboratories to assess their current practices, determine areas for improvement, and guide continuing professional development and education efforts. ©2010 American Society for Veterinary Clinical Pathology.

From Osler to Olafson. The evolution of veterinary pathology in North America.

PubMed Central

Saunders, L Z

1987-01-01

Most branches of biological science in North America developed first in the United States, and later were taught and practiced in Canada. An exception was veterinary pathology, which as a discipline taught in veterinary colleges and as a field of research, developed first in Canada, and from there crossed the border to the United States. Pathology was first taught at the Montreal Veterinary College, founded in 1866 by Duncan McEachran, a graduate of the Edinburgh Veterinary College. From the outset, he formed a close association with the medical faculty of McGill University, permitting his students to attend the same classes in the basic subjects with the medical students. Eventually, the Montreal Veterinary College became formally affiliated with McGill University, as the Faculty of Comparative Medicine and Veterinary Science. The McGill veterinary faculty was forced to close for economic reasons in 1903, but it left an enduring legacy, particularly in the field of veterinary pathology. The legacy, a novel concept in the 1870's, was that pathology was the cornerstone of a veterinary education; the place where anatomy, physiology, chemistry and botany met with the clinical subjects, and gave the latter meaning. This tradition was formed at the Montreal Veterinary College by the world renowned physician William Osler, North America's leading medical teacher, whom McEachran had invited to teach at the College in 1876 in addition to his duties in the faculty of medicine. Osler had studied with Virchow in Berlin and applied his methods of autopsy technique and of scientific inquiry to his teaching of both human and veterinary pathology at McGill. Osler also undertook investigations into various diseases of domestic animals, at the request of McEachran, who doubled as Chief Veterinary Inspector for the Dominion Department of Agriculture. Osler left McGill University in 1884. Only after that year did other North American veterinary schools adopt pathology as a discipline

This paper presents the results of Environmental and Personnel Dosimetry made in a radiology area of a veterinary hospital. Dosimetry was realized using thermoluminescent (TL) materials. Environmental Dosimetry results show that areas closer to the X-ray equipment are safe. Personnel Dosimetry shows important measurements of daily workday in some persons near to the limit established by ICRP. TL results of radiation measurement suggest TLDs are good candidates as a dosimeter to radiation dosimetry in veterinary radiology. Copyright © 2012 Elsevier Ltd. All rights reserved.

Acquired fistula of the lacrimal sac and laisser-faire approach. Description of the natural history of acquired fistulas between the lacrimal sac and the skin occurring before planned endonasal dacryocystorhinostomy (DCR) and without any treatment of the fistula.

The formation of a fistula between the lacrimal sac and the skin is a classic outcome of resistant lacrimal sac abscesses. There is currently no consensus about treatment in such cases. The goal of this study was to describe the natural history of acquired fistulas between the lacrimal sac and the skin, occurring before planned endonasal dacryocystorhinostomy (DCR) and without any treatment of the fistula. This prospective study was only descriptive and included patients between 1999 and 2012. The patients included were adults with a nasolacrimal duct (NLD) obstruction that was planned to be treated with endonasal DCR. A resistant lacrimal sac abscess appeared a few days before the planned surgery, and fistulized spontaneously despite medical treatment. The surgery was not delayed. The DCR was endoscopic. Nothing was done for the fistula. Its healing was spontaneous. The exclusion criteria were the following: congenital fistulas, post-traumatic and/or iatrogenic fistulas, fistulas which had regressed by the day of the surgery, postoperative follow-up less than 5 months, post-traumatic and/or iatrogenic fistulas, any history of previous DCR or any other lacrimal surgery, children. Twenty adults (25 cases) were included in the analysis. Mean age was 79 years old (from 41 to 90). The mean follow-up was 41 months (from 5 to 108 months). The fistula spontaneously disappeared in all cases, less than one month after it had appeared and in a permanent fashion. No unsightly scar developed. Spontaneously acquired fistulas between the lacrimal sac and the skin may occur in the natural course of abscessed acute dacryocystitis. Our study showed spontaneous healing of the fistula post-endoscopic DCR. Fistula excision in fistulous acute dacryocystitis does not seem essential to its healing. The laisser-faire approach appears adequate for aesthetic outcomes as well as for functional outcomes of DCR. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

This paper analyses how the changing governance of animal health has impacted upon veterinary expertise and its role in providing public health benefits. It argues that the social sciences can play an important role in understanding the nature of these changes, but also that their ideas and methods are, in part, responsible for them. The paper begins by examining how veterinary expertise came to be crucial to the regulation of the food chain in the twentieth century. The relationship between the veterinary profession and the state proved mutually beneficial, allowing the state to address the problems of animal health, and the veterinary profession to become identified as central to public health and food supply. However, this relationship has been gradually eroded by the application of neoliberal management techniques to the governance of animal health. This paper traces the impact of these techniques that have caused widespread unease within and beyond the veterinary profession about the consequences for its role in maintaining the public good of animal health. In conclusion, this paper suggests that the development of the social sciences in relation to animal health could contribute more helpfully to further changes in veterinary expertise. PMID:21624916

Veterinary pharmacovigilance (PV) is important for the Medicine which are used for treating disease in animals. It becomes more important when these animals are further used for producing food. Adverse drug reactions (ADRs) have a direct impact on animals and indirect impact on human beings, for example, through milk products, other animal producing food products. Currently, PV program of India is playing a vital role in assessing the safety of medicines in Indian Population. The safety of medicine in animals can be assessed by veterinary PV. The research institutes involved in animal research and veterinary hospitals can be considered as ADR monitoring centers to assess the safety of medicines on animals.

Three-dimensional morphological analysis of intracranial aneurysms: a fully automated method for aneurysm sac isolation and quantification.

Morphological descriptors are practical and essential biomarkers for diagnosis and treatment selection for intracranial aneurysm management according to the current guidelines in use. Nevertheless, relatively little work has been dedicated to improve the three-dimensional quantification of aneurysmal morphology, to automate the analysis, and hence to reduce the inherent intra and interobserver variability of manual analysis. In this paper we propose a methodology for the automated isolation and morphological quantification of saccular intracranial aneurysms based on a 3D representation of the vascular anatomy. This methodology is based on the analysis of the vasculature skeleton's topology and the subsequent application of concepts from deformable cylinders. These are expanded inside the parent vessel to identify different regions and discriminate the aneurysm sac from the parent vessel wall. The method renders as output the surface representation of the isolated aneurysm sac, which can then be quantified automatically. The proposed method provides the means for identifying the aneurysm neck in a deterministic way. The results obtained by the method were assessed in two ways: they were compared to manual measurements obtained by three independent clinicians as normally done during diagnosis and to automated measurements from manually isolated aneurysms by three independent operators, nonclinicians, experts in vascular image analysis. All the measurements were obtained using in-house tools. The results were qualitatively and quantitatively compared for a set of the saccular intracranial aneurysms (n = 26). Measurements performed on a synthetic phantom showed that the automated measurements obtained from manually isolated aneurysms where the most accurate. The differences between the measurements obtained by the clinicians and the manually isolated sacs were statistically significant (neck width: p <0.001, sac height: p = 0.002).

The objective of this study was to investigate the occurrence of veterinary drug residues in raw milk from Hebei, the second-largest dairy production province in the People's Republic of China. A total of 192 raw milk samples were collected from 64 milk stations in seven districts. Twenty-eight veterinary drug residues were analyzed by ultraperformance liquid chromatography with tandem mass spectrometry based on a China National Standard. Raw milk samples with multiple residues of veterinary drugs were not found in the present study. Residues of four veterinary drugs, penicillin G, sulfacetamide, trimethoprim, and lincomycin, were detected in 12 (6.25%) raw milk samples, with detection ratios of 1.04, 0.52, 3.13, and 1.56%, respectively. All veterinary drug residues detected were under the maximum residue levels as regulated by China, the European Union, the United States, and the Codex Alimentarius Commission. In general, raw milk from Hebei province was considered relatively safe for human consumption because of the low prevalence of veterinary drug residues. However, stringent control measurements for veterinary drug residues in raw milk are required because some veterinary drugs were detected in milk from some areas of Hebei province.

To assess veterinary extension in the United States as perceived by veterinary extension personnel. Cross-sectional survey. Extension veterinarians in the United States. 2 surveys were designed and mailed to extension veterinarians listed by the USDA and the American Association of Extension Veterinarians. 34 states had > or = 1 extension veterinarian. The majority (> 60%) of extension veterinarians did not commit time to resident education and were not involved in research activities. Paradoxically, 23% of responding extension veterinarians did not report extension work. Programs for food animal producers, horse owners, and companion animal owners were provided by 100, 63, and 37% of states, respectively. Continuing education (CE) programs were provided for food animal veterinarians, equine veterinarians, and companion animal veterinarians by 96, 63, and 52% of states, respectively. Challenges facing veterinary extension included limited recognition of veterinary extension activities by universities, lack of university personnel to support CE programs, and decreased support for companion animal extension programs. Extension veterinarians need to identify and clearly articulate the mission of veterinary extension, develop more collaborative programs across regions, and continue to serve as catalysts to bring diverse constituents together. Extension veterinarians must distinguish their mission not solely as information transfer, which can be accomplished in a variety of ways outside of extension, but as a coherent and consistent program of education and policy developed on a national level and distributed locally.

The Sports Concussion Assessment Tool 2 (SCAT2) and King-Devick (K-D) tests have both been proposed as sideline tools to detect sports-related concussion. We performed an exploratory analysis to determine the relation of SCAT2 components, particularly the Standardized Assessment of Concussion (SAC), to K-D test scores in a professional ice hockey team cohort during pre-season baseline testing. We also examined changes in scores for two athletes who developed concussion and had rinkside testing. A modified SCAT2 (no balance testing) and the K-D test, a brief measure of rapid number naming, were administered to 27 members of a professional ice hockey team during the 2011-2012 pre-season. Athletes with concussion also underwent rinkside testing. Lower (worse) scores for the SCAT2 SAC Immediate Memory Score and the overall SAC score were associated with greater (worse) times required to complete the K-D test at baseline. On average, for every 1-point reduction in SAC Immediate Memory Score, we found a corresponding increase (worsening) of K-D time score of 7.3s (95% CI 4.9, 9.7, p<0.001, R(2)=0.62, linear regression, accounting for age). For the overall SAC score, 1-point reductions were associated with K-D score worsening of 2.2s (95% CI 0.6, 3.8, p=0.01, R(2)=0.25, linear regression). In two players tested rinkside immediately following concussion, K-D test scores worsened from baseline by 4.2 and 6.4s. These athletes had no differences found for SCAT2 SAC components, but reported symptoms of concussion. In this study of professional athletes, scores for the K-D test, a measure for which saccadic (fast) eye movements are required for the task of rapid number naming, were associated with reductions in Immediate Memory at a pre-season baseline. Both working memory and saccadic eye movements share closely related anatomical structures, including the dorsolateral prefrontal cortex (DLPFC).

The aim was to evaluate long-term outcomes and sac volume shrinkage after endovascular popliteal artery aneurysm repair (EVPAR). This study was a retrospective review of all EVPAR cases between 1999 and 2012. Sac volume shrinkage, long-term patency, limb salvage, and survival were evaluated using Kaplan-Meier estimates. The association of anatomical and clinical characteristics with patency was evaluated using multivariate analysis. Forty-six EVPAR were carried out in 42 patients (mean age 78 years, 86% male; mean sac volume 45.5 ± 3.5 mL). In 93% of cases (n = 43) the procedure was elective, while in 7% of cases it was for rupture (n = 2) or acute thrombosis (n = 1). Of the 43 patients who underwent elective repair, 58% were asymptomatic and 42% symptomatic (14 claudication, 3 rest pain, and 1 compression symptoms). Technical success was 98%. Mean duration of follow-up was 56 ± 21 months. Primary patency at 1, 3, and 5 years was 82% (SE 2), 79% (SE 4), and 76% (SE 4), while secondary patency was 90% (SE 5), 85% (SE 4), and 82% (SE 1) respectively; at 5 years there was 98% limb salvage and an 84% survival rate. During follow-up 11 limbs had stent graft failure: six required conversion, one underwent amputation, and four continued with mild claudication. Of those with graft failure, 63% (7/11) occurred within the first year of follow-up. The mean aneurysm sac volume shrinkage between preoperative and 5-year post-procedure measurement was significant (45.5 ± 3.5 mL vs. 23.0 ± 5.0 mL; p < .001). Segment coverage >20 cm was a negative predictor for patency (HR 2.76; 95% CI 0.23; p = .032). EVPAR provides successful aneurysm exclusion with good long-term patency, excellent limb salvage, and survival rates. Close surveillance is nevertheless required, particularly during the first postoperative year. Patients requiring long segment coverage (>20 cm) may be at increased risk for failure.

To evaluate how the veterinary profession is represented in nonfiction children's books and determine whether representations reflect the current veterinary profession or the demographics of the United States. Survey. Covers of 46 nonfiction children's books and contents of 45 nonfiction children's books. Book covers and book contents (images and text) were evaluated for representations of veterinarians and to identify settings, clients, technology and equipment, and animals portrayed. Book contents were additionally evaluated to identify specialties and career opportunities specifically mentioned in the text. Book covers predominantly portrayed veterinarians as Caucasian women who wore examination coats, worked alone in veterinary clinics, and cared for dogs without a client present. Book contents predominantly portrayed veterinarians as a Caucasian man or woman who wore an examination coat, worked as part of a team in a veterinary clinic, and helped clients care for dogs, cats, and exotic animals. Specialties and career opportunities in the veterinary profession were mentioned in the text of 29 of 45 (64.4%) books. Nonfiction children's book covers that focused on the veterinary profession portrayed a greater percentage of women than is currently found in the profession. Similarly, books portrayed a greater percentage of Caucasians than in the current or predicted US population. With the exception of Asians, books collectively represented lower or similar percentages of underrepresented minorities, compared with the US population. Veterinarians are encouraged to select books for individual children that portray veterinarians with whom the children can identify.

Milestone Educational Planning Initiatives in Veterinary Medical Education: Progress and Pitfalls.

Three milestone educational planning initiatives engaged the veterinary medical profession in the United States and Canada between 1987 and 2011, namely the Pew National Veterinary Education Program, the Foresight Project, and the North American Veterinary Medical Education Consortium. In a quantitative study, we investigated the impact of these initiatives on veterinary medical education through a survey of academic leaders (deans, previous deans, and associate deans for academics from veterinary medical schools that are members of the Association of American Veterinary Medical Colleges) to assess their perspectives on the initiatives and eight recommendations that were common to all three initiatives. Two of the recommendations have in effect been implemented: enable students to elect in-depth instruction and experience within a practice theme or discipline area (tracking), and increase the number of graduating veterinarians. For three of the recommendations, awareness of the issues has increased but substantial progress has not been made: promote diversity in the veterinary profession, develop a plan to reduce student debt, and develop a North American strategic plan. Lastly, three recommendations have not been accomplished: emphasize use of information more than fact recall, share educational resources to enable a cost-effective education, and standardize core admissions requirements. The educational planning initiatives did provide collaborative opportunities to discuss and determine what needs to change within veterinary medical education. Future initiatives should explore how to avoid and overcome obstacles to successful implementation.

Antimicrobial drug use in veterinary medicine.

Morley, Paul S; Apley, Michael D; Besser, Thomas E; Burney, Derek P; Fedorka-Cray, Paula J; Papich, Mark G; Traub-Dargatz, Josie L; Weese, J Scott

Recognizing the importance of antimicrobial resistance and the need for veterinarians to aid in efforts for maintaining the usefulness of antimicrobial drugs in animals and humans, the Board of Regents of the American College of Veterinary Internal Medicine charged a special committee with responsibility for drafting this position statement regarding antimicrobial drug use in veterinary medicine. The Committee believes that veterinarians are obligated to balance the well-being of animals under their care with the protection of other animals and public health. Therefore, if an animal's medical condition can be reasonably expected to improve as a result of treatment with antimicrobial drugs, and the animal is under a veterinarian's care with an appropriate veterinarian-client-patient relationship, veterinarians have an obligation to offer antimicrobial treatment as a therapeutic option. Veterinarians also have an obligation to actively promote disease prevention efforts, to treat as conservatively as possible, and to explain the potential consequences associated with antimicrobial treatment to animal owners and managers, including the possibility of promoting selection of resistant bacteria. However, the consequences of losing usefulness of an antimicrobial drug that is used as a last resort in humans or animals with resistant bacterial infections might be unacceptable from a public or population health perspective. Veterinarians could therefore face the difficult choice of treating animals with a drug that is less likely to be successful, possibly resulting in prolonged or exacerbated morbidity, to protect the good of society. The Committee recommends that voluntary actions be taken by the veterinary profession to promote conservative use of antimicrobial drugs to minimize the potential adverse effects on animal or human health. The veterinary profession must work to educate all veterinarians about issues related to conservative antimicrobial drug use and

Effect of aluminum on bidirectional calcium flux in rat everted intestinal sacs.

PubMed

Adler, A J; Zara, C; Berlyne, G M

1989-09-01

The effect of aluminum on intestinal calcium absorption was determined in male Sprague-Dawley rats using an everted intestinal sac technique. Bidirectional calcium flux in the duodena and ilea of normal rats was assessed by means of dual calcium isotopes. Two micromolar aluminum significantly inhibited net calcium absorption (J net) in the duodenum through suppression of mucosato-serosa flux (J m----s). Jm----s was reduced from 2.21 +/- 0.50 mumol Ca.h-1.g wet wt-1 in controls to 0.93 +/- 0.35 mumol Ca.h-1.g-1 in aluminum exposed sacs, and Jnet was reduced from 1.88 +/- 0.14 mumol Ca.h-1.g-1 to 0.55 +/- 0.41 mumol Ca.h-1.g-1 (P less than 0.001). Serosa-to-mucosa calcium flux (Js----m) was not similarly influenced by aluminum. Inhibition of Jm----s occurred whether aluminum was initially present on the mucosal or serosal side of the duodenal sac and inhibition of Jnet calcium by 2 muM A1 occurred at all ambient concentrations of calcium studied. In the ileum, aluminum had no effect on any component of calcium flux. Aluminum did not induce any suppression of glucose transport in either the duodenum or ileum, suggesting that the effect on calcium transport is relatively specific. These results suggest that aluminum inhibits calcium absorption in the duodenum through an effect on active mucosa-to-serosa transport, but has no effect on ileal calcium absorption, which in the rat is not mediated by an active process.

Interest in the areas of food animals (FA) and veterinary public health (VPH) appears to be declining among prospective students of veterinary medicine. To address the expected shortage of veterinarians in these areas, the Utrecht Faculty of Veterinary Medicine has developed an admissions procedure to select undergraduates whose aptitude and interests are suited to these areas. A study using expert meetings, open interviews, and document analysis identified personal characteristics that distinguished veterinarians working in the areas of FA and VPH from their colleagues who specialized in companion animals (CA) and equine medicine (E). The outcomes were used to create a written selection tool. We validated this tool in a study among undergraduate veterinary students in their final (sixth) year before graduation. The applicability of the tool was verified in a study among first-year students who had opted to pursue either FA/VPH or CA/E. The tool revealed statistically significant differences with acceptable effect sizes between the two student groups. Because the written selection tool did not cover all of the differences between the veterinarians who specialized in FA/VPH and those who specialized in CA/E, we developed a prestructured panel interview and added it to the questionnaire. The evaluation of the written component showed that it was suitable for selecting those students who were most likely to succeed in the FA/VPH track.

Steatorrhoea in rats with an intestinal cul-de-sac is mainly due to malabsorption of alimentary fats but faecal lipids of endogenous origin are also increased. Steatorrhoea depends on the site of the blind loop in the small intestine and is mainly caused by bacterial proliferation in the lumen of the gut. The aetiological role of Gram-positive anaerobic microbes, especially Clostridium welchii, is suggested. ImagesFIG. 3FIG. 4FIG. 5FIG. 6 PMID:14209913

The sacB gene from Bacillus subtilis confers sucrose sensitivity upon gram-negative bacteria. The gene was investigated for use as a potential conditional suicide system for Escherichia coli released into soil. To ensure against the loss of the cell death function encoded under nonselective conditions, the nptI-sacR-B suicide cassette was inserted into the E. coli chromosome by using a circular nonreplicative integration vector. Stability studies yielded no loss of the suicide cassette in the integrated E. coli EL1026 strain. sacB induction in the absence of a selective pressure resulted in a lysis efficiency of up to 99.9%. The microcosm experiments confirmed the ability of the suicide cassette to limit the growth and reduce the survival of E. coli strains released into soil. Sucrose addition to sterile soil resulted in a 10(-3)-fold reduction of the final E. coli population density. sacB induction prevented the proliferation and triggered the rapid disappearance of E. coli from natural soil. Mutation to sucrose tolerance occurred at a frequency of 10(-5), making E. coli EL1026 a potential counterselectable donor strain for gene transfer studies. Specificity and potential adaptability to a wide range of gram-negative bacteria are additional conveniences of this conditional suicide system for the containment and counterselection of engineered microorganisms.
