Impact of time-limited feeding and dietary carbohydrate content on weight loss in group-housed cats     

Michel KE  Bader A  Shofer FS  Barbera C  Oakley DA  Giger U 《Journal of Feline Medicine and Surgery》2005,7(6):349-355

Twenty-four adult cats were transitioned to time-limited feeding and randomized to either a dry low carbohydrate diet (LC) or a dry reduced energy diet (HC). In Trial 1 the LC and HC groups received equal amounts of food (by weight) for 13 weeks. Both groups consumed all food offered, hence the LC group received more energy/day than the HC group. In Trial 2 all cats were fed the LC diet for 12 weeks, but each group received the energy that the opposite group had received in Trial 1. In Trial 1 only the overweight HC cats (body condition score> 6/9) experienced a significant change in body weight (-0.52 +/- 0.08 kg). In Trial 2, LC/Low Calorie overweight cats lost 0.62 +/- 0.10 kg, whereas, the LC/High Calorie normal weight cats gained 0.68 +/- 0.05 kg. In conclusion, body condition and energy intake but not type of diet influenced weight in this cohort of group-housed cats.  相似文献   

Immunohistochemical characterization of a malignant intraocular teratoid medulloepithelioma in a cockatiel     

Bras ID  Gemensky-Metzler AJ  Kusewitt DF  Colitz CM  Wilkie DA 《Veterinary ophthalmology》2005,8(1):59-65

A 3-year-old cockatiel was presented for evaluation of a buphthalmic right eye (OD). The history included a traumatic event 5 months prior to presentation, and the referring veterinarian diagnosed cataract and secondary glaucoma. Computed tomography of the bird's orbital region revealed a large right orbital soft tissue mass that extended lateral to the orbital rim with obliteration of the globe without bone involvement. There was also no evidence of metastatic disease within the lungs or any abnormalities within the celomic cavity, therefore enucleation was recommended to achieve a histopathologic diagnosis and prognosis, and to palliate the clinical signs. Final diagnosis was malignant intraocular teratoid medulloepithelioma.  相似文献   

A comparison of knot security of commonly used hand-tied laparoscopic slipknots     

Shettko DL  Frisbie DD  Hendrickson DA 《Veterinary surgery : VS》2004,33(5):521-524

OBJECTIVE: To compare the peak force required for failure of hand-tied laparoscopic slipknot ligatures. STUDY DESIGN: In vitro mechanical evaluation of suture material/knot combinations. Sample POPULATION: Four hand-tied laparoscopic slipknots were studied. Three suture materials and 2 suture sizes were evaluated. Twenty samples of each group were tested, for a total of 400 samples. METHODS: The 4S modified Roeder, modified Roeder, and Weston and Brooks laparoscopic slipknots using 0 polyglyconate, 0 polyglycolic acid, 1 polyglyconate, and 1 polydioxanone (PDS) were tested. A vertical distracting force (5 mm/s) was applied until failure. Mean peak force to failure was obtained for each suture material, size, and knot combination. RESULTS: Mean (+/-SEM) peak force to failure of hand-tied ligatures ranged from 156.8+/-9.1 N to 4.8+/-.4 N. The 4S-modified Roeder had the highest mean peak force to failure. Ligatures tied with polyglyconate and size 1 suture had the highest mean peak force to failure. CONCLUSIONS: The 4S-modified Roeder was significantly and consistently stronger than the other slipknots. Polyglyconate was superior to other suture materials. The 1 polyglyconate had the highest mean peak force to failure followed by 0 polyglyconate that exceeded the 1PDS. CLINICAL RELEVANCE: The 4S-modified Roeder slipknot using 1 polyglyconate has the greatest breaking strength of sutures tested and should be considered when performing laparoscopic ligatures.  相似文献   

Hospital management principles applicable to the veterinary teaching hospital     

Harris DL  Lloyd JW  Marrinan M 《Journal of veterinary medical education》2004,31(3):273-280

The Skills, Knowledge, Aptitude, and Attitude (SKA) Subcommittee of the National Commission on Veterinary Economic Issues (NCVEI) has identified the need for veterinary teaching hospitals (VTH) to be at the forefront of progressive business management to serve as a model for both students and practitioners to emulate. To provide a foundation for developing a model, this study reviewed pertinent literature applicable to the management of a VTH. Much of the literature relevant to VTH management relates to work completed for the human side of medicine (academic health centers, or AHCs) or to the private sector. This review explores management practices in strategic planning, financial management, human resource management, marketing, pricing, operations, and legal issues. It is concluded that strategic management is important to provide the foundation for success in the VTH. In addition, periodic financial reports are recommended, as are the development and use of benchmarks for financial management. Establishing positive, motivating human resource practices is also suggested, along with development of a marketing plan based on a clear understanding of VTH core competencies and the market's specific needs.  相似文献

Race, ethnicity, and NIH research awards     

Ginther DK  Schaffer WT  Schnell J  Masimore B  Liu F  Haak LL  Kington R 《Science (New York, N.Y.)》2011,333(6045):1015-1019

We investigated the association between a U.S. National Institutes of Health (NIH) R01 applicant's self-identified race or ethnicity and the probability of receiving an award by using data from the NIH IMPAC II grant database, the Thomson Reuters Web of Science, and other sources. Although proposals with strong priority scores were equally likely to be funded regardless of race, we find that Asians are 4 percentage points and black or African-American applicants are 13 percentage points less likely to receive NIH investigator-initiated research funding compared with whites. After controlling for the applicant's educational background, country of origin, training, previous research awards, publication record, and employer characteristics, we find that black applicants remain 10 percentage points less likely than whites to be awarded NIH research funding. Our results suggest some leverage points for policy intervention.  相似文献

Interspecific differences in dead plant buffering capacity alter the impact of acid rain on decomposition rates in tidal marshes     

John L. Gallagher  Lisa A. Donovan  Donna M. Grant  Debra M. Decker 《Water, air, and soil pollution》1987,34(4):339-346

Simulated acid rain did not alter respiration rates of microbial associations on dead Spartina alterniora from Delaware salt marshes or on dead Carex lyngbyei from Oregon brackish marshes. Since these dead plant-microbe associations have a strong buffering capacity for acid rain, the microbial associations did not experience a low pH. In contrast, Phragmites australis has a low buffering capacity and microbial respiration was reduced at least 25 % by acid rain. When dead plant-microbe associations from freshwater marshes and various terrestrial plant populations were immersed in simulated acid rain, the rain water equilibrated at pH's from 3.9 to 5.0 and were characteristic of the various species. The different buffering capacities of such dead plant-microbe associations may explain the inconsistent results published from decomposition studies and may serve as a quick and easy method of assessing the probable impact of acidic deposition on decomposition processes.  相似文献
