Influence of cluster exposure on fruit composition and wine quality of Seyval blanc grapes

Experiments were conducted in 1981 and 1982 to investigate the influence of duster exposure on fruit composition, wine quality, and incidence of bunch rot (Botrytis cinerea PERS.) of the French-American hybrid grape cultivar Seyval blanc. Berry sampling from 4 exposure categories (western exposure, eastern exposure, partial shade, and full shade) indicated highest °Brix, pH and tartrate, and lowest titratable acidity (TA) and malate in the exposed fruit post veraison. Total acidity and malate were highest in exposed fruit between fruit set and veraison. Exposure of the fruit also reduced the incidence of bunch rot during the 1981 season. Wine quality differences were small and not statistically significant, although wines vinted from exposed fruit tended to score higher. Canopy management practices that optimize fruit exposure would be helpful in maximization of fruit and wine quality

Resveratrol and the viniferins, their application to screening for disease resistance in grape breeding programs

We have confirmed the findings of LANGCAKB and PRYCE and extended them to include species which have significant resistance to disease. Using these species we have observed differential production of resveratrol both within and among clones in relation to the incidence of disease. The techniques we have used fit the requirements of a screening technique. Unlike the analytic technique most recently used by LANGCAKE and McCARTHY (6) resveratrol and the viniferins are separated in our procedures. Minimal amounts of tissue are required, and TLC combined with either  UV or fluorescence spectrophotometry give rapid quantitative results. The use of UV to induce the production of these "stress metabolites" would free the breeder from the necessity of maintaining fungus cultures for inoculation tests. Further study must be done to elaborate the role of these compounds in disease resistance and the efficacy of their role in predicting resistance.Resveratrol und die Viniferine - ihre Verwendbarkeit bei der Bonitierung der Pilzresistenz im Rahmen von RebenzüchtungsprogrammenDie Ergebnisse von LANGCAKE und PRICE bezüglich der Phytoalexinbildung bei Reben wurden bestätigt; entsprechende Befunde ließen sich auch bei einer Ausdehnung der Untersuchungen auf Rebenarten, die eine hohe Pilzresistenz besitzen, aufzeigen. Bei diesen Species wurde sowohl innerhalb der Klone wie auch zwischen den Klonen eine abgestufte Resveratrolbildung beobachtet, die in Beziehung zum Auftreten von Pilzkrankheiten stand. Die angewandte Technik erfüllt die Anforderungen, die an eine Bonitierungsmethode zu stellen sind. Resveratrol und die Viniferine konnten nunmehr gesondert bestimmt werden. Hierzu sind nur geringe Mengen von Rebenmaterial erforderlich, und mittels Dünnschichtchromatographie in Verbindung mit UV- oder Fluoreszenzspektrophotometrie lassen sich rasch quantitative Ergebnisse erzielen. Die Verwendung von UV-Licht zur Induktion der „Streßmetabolite" würde den Züchter der Notwendigkeit entheben, Pilzkulturen für Inokulationstests zu halten. Zum besseren Verständnis der Rolle, die diese Verbindungen bei der Pilzresistenz spielen, sind ebenso wie bezüglich ihrer Verwendung zur Resistenzvorhersage weitere Untersuchungen erforderlich

Surgical management of chronic otitis secondary to craniomandibular osteopathy in three West Highland white terriers

Three West Highland white terriers were presented for investigation of left‐sided para‐aural abscessation. CT revealed chronic otitis media with extensive osseous proliferation surrounding the horizontal and vertical ear canals contiguous with the expanded temporal bone, consistent with a unilateral variant of craniomandibular osteopathy. A left total ear canal ablation with lateral bulla osteotomy was performed in all dogs. An ultrasonic bone curette (Sonopet; Stryker) proved useful when removing the osseous proliferation in two dogs. Histopathological examination of the ear canals was consistent with craniomandibular osteopathy and the treatment led to resolution of the presenting clinical signs in all dogs. To our knowledge, this is the first report of craniomandibular osteopathy engulfing the external ear canal, presumably leading to chronic otitis media and para‐aural abscess formation. This is also the first reported use of an ultrasonic bone curette in canine otic surgery

Spinal manipulation and mobilisation in paediatrics–an international evidence-based position statement for physiotherapists

Introduction: An international taskforce of clinician-scientists was formed by specialty groups of World Physiotherapy–International Federation of Orthopaedic Manipulative Physical Therapists (IFOMPT) &amp; International Organisation of Physiotherapists in Paediatrics (IOPTP)–to develop evidence-based practice position statements directing physiotherapists clinical reasoning for the safe and effective use of spinal manipulation and mobilisation for paediatric populations (&lt;18 years) with varied musculoskeletal or non-musculoskeletal conditions. Method: A three-stage guideline process using validated methodology was completed: 1. Literature review stage (one scoping review, two reviews exploring psychometric properties); 2. Delphi stage (one 3-Round expert Delphi survey); and 3. Refinement stage (evidence-to-decision summative analysis, position statement development, evidence gap map analyses, and multilayer review processes). Results: Evidence-based practice position statements were developed to guide the appropriate use of spinal manipulation and mobilisation for paediatric populations. All were predicated on clinicians using biopsychosocial clinical reasoning to determine when the intervention is appropriate. 1. It is not recommended to perform: • Spinal manipulation and mobilisation on infants. • Cervical and lumbar spine manipulation on children. •Spinal manipulation and mobilisation on infants, children, and adolescents for non-musculoskeletal paediatric conditions including asthma, attention deficit hyperactivity disorder, autism spectrum disorder, breastfeeding difficulties, cerebral palsy, infantile colic, nocturnal enuresis, and otitis media. 2. It may be appropriate to treat musculoskeletal conditions including spinal mobility impairments associated with neck-back pain and neck pain with headache utilising: • Spinal mobilisation and manipulation on adolescents; • Spinal mobilisation on children; or • Thoracic manipulation on children for neck-back pain only. 3. No high certainty evidence to recommend these interventions was available. Reports of mild to severe harms exist; however, risk rates could not be determined. Conclusion: Specific directives to guide physiotherapists’ clinical reasoning on the appropriate use of spinal manipulation or mobilisation were identified. Future research should focus on trials for priority conditions (neck-back pain) in children and adolescents, psychometric properties of key outcome measures, knowledge translation, and harms.</p

VIS: the visible imager for Euclid

Euclid-VIS is a large format visible imager for the ESA Euclid space mission in their Cosmic Vision program, scheduled for launch in 2019. Together with the near infrared imaging within the NISP instrument it forms the basis of the weak lensing measurements of Euclid. VIS will image in a single r+i+z band from 550-900 nm over a field of view of ~0.5 deg2. By combining 4 exposures with a total of 2240 sec, VIS will reach to V=24.5 (10{\sigma}) for sources with extent ~0.3 arcsec. The image sampling is 0.1 arcsec. VIS will provide deep imaging with a tightly controlled and stable point spread function (PSF) over a wide survey area of 15000 deg2 to measure the cosmic shear from nearly 1.5 billion galaxies to high levels of accuracy, from which the cosmological parameters will be measured. In addition, VIS will also provide a legacy imaging dataset with an unprecedented combination of spatial resolution, depth and area covering most of the extra-Galactic sky. Here we will present the results of the study carried out by the Euclid Consortium during the Euclid Definition phase.Comment: 10 pages, 6 figure
