Treatment of a pulmonary granular cell tumour by repeated transendoscopic diode laser photoablation          下载免费PDF全文

N. Van Heesewijk  E. J. Knowles  C. J. Palgrave  T. S. Mair 《Equine Veterinary Education》2015,27(6):302-305

A 27‐year‐old Shetland mare was examined for persistent coughing, increased respiratory rate and mild exercise intolerance. Over the previous 5 months, the mare had experienced a persistent cough nonresponsive to medical and environmental management. Upon endoscopic examination of the lower airways, a mass was seen within the left mainstem bronchus; biopsy identified a granular cell tumour. The tumour was successfully reduced by repeated transendoscopic diode laser photoablation over a period of 4 months with no evidence of recurrence at 10 months post treatment.  相似文献   

Huckleberry Gold: A Specialty Market Potato Cultivar with Purple-Skin,Yellow-Flesh,High Tuber Antioxidants,and Resistance to Potato Cyst Nematode (H1) and Potato virus X (Nb and Rx1)     

Jonathan L. Whitworth  Richard G. Novy  Jeffrey C. Stark  Stephen L. Love  Michael K. Thornton  Brian A. Charlton  Solomon Yilma  N. Richard Knowles  Mark J. Pavek  Xiaohong Wang  Joseph J. Pavek 《American Journal of Potato Research》2014,91(5):447-458

Huckleberry Gold is a purple-skin, yellow-flesh fresh market cultivar with similar culinary qualities to the market standard Yukon Gold. It has lower specific gravity, sucrose and vitamin C content, but a significantly higher level of tuber antioxidants than Yukon Gold. Notable disease resistant characteristics are Potato virus X resistance based on the presence of molecular markers for the PVX resistance genes, Nb and Rx1. In addition it also has the H1 gene present which confers resistance to the potato cyst nematode, Globodera rostochiensis, which has been confirmed by bioassay to pathotype Ro1. The size profile of Huckleberry Gold is smaller than Yukon Gold, allowing a better fit into specialty markets that are geared to smaller size for fresh use. Huckleberry Gold represents the first purple-skin, yellow-flesh cultivar to come from the Northwest (Tri-State) Potato Variety Development program.  相似文献   

Real-time, very-long-baseline interferometry based on the use of a communications satellite     

Yen JL  Kellermann KI  Rayhrer B  Broten NW  Fort DN  Knowles SH  Waltman WB  Swenson GW 《Science (New York, N.Y.)》1977,198(4314):289-291

The Hermes satellite, a joint Canadian-American program, has been used to provide a communication channel between radio telescopes in West Virginia and Ontario, for very-long-baseline interferometry (VLBI). This system makes possible instantaneous correlation of the data as well as a sensitivity substantially better than that of earlier VLBI systems, by virtue of a broader observational bandwidth. With the use of a geostationary communications satellite it is possible to eliminate the tape recorders and the most troublesome part of the postobservational data processing. A further possibility is the development of a phase-coherent interferometer.  相似文献   

Summit Russet: A new russet potato variety with good fresh market and frozen processing qualities     

S. L. Love  R. Novy  J. Whitworth  D. L. Corsini  J. J. Pavek  A. R. Mosley  R. E. Thornton  N. R. Knowles  S. R. James  D. C. Hane 《American Journal of Potato Research》2005,82(6):425-432

Summit Russet (A84118-3), the result of the cross A77236-6 x TND329-1Russ, was released in 2003 by the USDA/ARS and the Agricultural Experiment Stations of Idaho, Oregon, and Washington. The vines of Summit Russet are erect, with very thick stems, large yellowish-green leaves and abundant white flowers. The tubers are tan, with medium russet skin, long-flattened shape, a slightly prominent eyebrow, white flesh, and moderately prominent pith. Tuber dormancy is very long. Summit Russet was compared with Russet Burbank in trials across the Pacific Northwest for yield, quality, and disease response. In general, Summit Russet produced similar or lower total yields than did Russet Burbank, but higher U.S. No. 1 yields. In Idaho variety trials, Summit Russet exhibited resistance to second growth, growth cracks, blackspot bruise, and stem-end discoloration, and moderate susceptibility to hollow heart and shatter bruise. In comprehensive product quality evaluations, Summit Russet was rated superior to Russet Burbank for french fry quality and similar for baked potato quality. French fry quality was retained after long-term storage. In replicated disease trials, Summit Russet was found to have good resistance to common scab, early blight tuber rot, and Verticillium wilt, and moderate resistance to Fusarium dry rot and tuber net necrosis caused by PLRV. It demonstrated susceptibility to late blight, foliar PLRV, PVX, PVY^o, and bacterial soft rot. Biochemical analysis of Summit Russet tubers showed them to be higher in total solids and sucrose, and lower in dextrose than those of Russet Burbank. Tuber glycoalkaloid concentration as measured from tubers produced in 1994–1996 trials was 6.7 mg 100 g¹.  相似文献   

Factors influencing incidence of internal brown spot in Russet Burbank potatoes     

W. M. Iritani  L. D. Weller  N. R. Knowles 《American Journal of Potato Research》1984,61(6):335-343

Studies were conducted to determine factors influencing incidence of internal brown spot (IBS) in Russet Burbank potatoes. A significant decrease in the incidence of IBS occurred as planting date was delayed from March 31 to May 12. IBS increased during storage particularly at the higher storage temperature and in larger tubers. Foliar application of maleic hydrazide (MH) significantly reduced IBS from a high of 33% of tubers to less than 10%. The incidence of IBS in tubers was lower in the field as well as in storage from plants sprayed with MH. Tubers with high specific gravity had greater incidence of IBS than low gravity tubers. Results indicate that IBS is a physiological disorder influenced by factors affecting growth of tubers.  相似文献   

Achieving consensus on current and future priorities for farmed fish welfare: a case study from the UK     

I. K. Berrill  T. Cooper  C. M. MacIntyre  T. Ellis  T. G. Knowles  E. K. M. Jones  J. F. Turnbull 《Fish physiology and biochemistry》2012,38(1):219-229

The welfare of farmed fish has attracted attention in recent years, which has resulted in notable changes within the aquaculture industry. However, a lack of communication between stakeholders and opposing ethical views are perceived as barriers to achieving consensus on how to improve farmed fish welfare. To address these issues, we developed an interactive approach that could be used during stakeholder meetings to (1) improve communication between different stakeholder groups, (2) build consensus on priorities for farmed fish welfare and (3) establish mechanisms to address welfare priorities. We then applied this approach during a meeting of stakeholders to identify current and future priorities for farmed fish welfare in the UK. During the meeting in the UK, stakeholders initially identified 32 areas that they felt were in need of development for future improvements in farmed fish welfare. These were further refined via peer review and discussion to the seven most important “priority” areas. Establishing a “better understanding of what good fish welfare is” emerged as the highest priority area for farmed fish welfare. The second highest priority area was “the need for welfare monitoring and documentation systems”, with mortality recording proposed as an example. The other five priority areas were “[improved understanding of] the role of genetic selection in producing fish suited to the farming environment”, “a need for integration and application of behavioural and physiological measures”, “the need for a more liberal regime in Europe for introducing new medicines”, “a need to address the issues of training existing and new workers within the industry”, and “ensuring best practise in aquaculture is followed by individual businesses”. Feedback from attendees, and the meeting outputs, indicated that the approach had been successful in improving communication between stakeholders and in achieving consensus on the priorities for farmed fish welfare. The approach therefore proved highly beneficial for future improvements in fish welfare in the UK.  相似文献
