Published 1983Staff ViewISSN: 1365-2044Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: The purpose of the study was to investigate the role of flexible bronchoscopy in the management of patients admitted to a busy Regional burns unit, with particular reference to possible smoke inhalation injury. The basic procedure employed was that used in routine bronchoscopy for the diagnosis of bronchial carcinoma, with modification of the premedication required in view of the shorter duration of the technique and the lack of a requirement for bronchial biopsy. We have found the procedure easy to perform, well tolerated by the patients and not associated with any complications. It provides additional information not otherwise available, which can influence the subsequent management of the patient. An experienced bronchoscopist and additional personnel skilled in resuscitation techniques are required. It should be performed in patients with clear evidence of smoke inhalation injury and in particular with facial burns in order to visualise the extent of airway injury, remove debris and give some indication of the likelihood of subsequent complications such as acute upper airways obstruction.Type of Medium: Electronic ResourceURL: -

ISSN: 1365-3040Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyNotes: Previous reports suggest that in some plant species the refilling of embolized xylem vessels can occur while negative pressure exists in the xylem. The aim of this experiment was to use non-destructive nuclear magnetic resonance imaging (MRI) to study the dynamics of xylem cavitation and embolism repair in-vivo. Serial 1H-MRI was used to monitor the contents of xylem vessels in stems of two dicotyledonous (Actinidia deliciosa and Actinidia chinensis, kiwifruit) and one monocotyledonous (Ripogonum scandens, supplejack) species of woody liana. The configuration of the horizontal wide bore magnet and probe allowed the imaging of woody stems up to 20 mm in diameter. Tests using excised stems confirmed that the image resolution of 78 µm and digital image subtraction could be used to detect the emptying and refilling of individual vessels. Imaging was conducted on both intact plants and excised shoots connected to a water supply. In the case of Ripogonum the excised shoots were long enough to allow the distal end of the shoot, including all leaves, to be exposed to ambient conditions outside the building while the proximal end was inside the MRI magnet. In total, six stems were monitored for 240 h while the shoots were subjected to treatments that included light and dark periods, water stress followed by re-watering, and the covering of all leaves to prevent transpiration. The sudden emptying of water-filled vessels occurred frequently while xylem water potential was low (below −0.5 MPa for Actinidia, −1.0 MPa for Ripogonum), and less frequently after xylem water potential approached zero at the end of water-stress treatments. No refilling of empty vessels was observed at any time in any of the species examined. It is concluded that embolism repair under negative pressure does not occur in the species examined here. Embolism repair may be more likely in species with narrower xylem vessels, but further experiments are required with other species before it can be concluded that repair during transpiration is a widespread phenomenon.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-5036Keywords: Actinidia deliciosa ; foliar analysis ; kiwifruit ; magnesium deficiency ; mineral nutrition ; postharvest fruit storageSource: Springer Online Journal Archives 1860-2000Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: Abstract Magnesium deficiency was associated with large yield reductions in a five-year-old commercial kiwifruit (Actinidia deliciosa) orchard. The effect on yield resulted primarily from a reduction in fruit numbers, there being no difference in mean fruit weight between fruit harvested from affected and unaffected vines. Magnesium deficiency had no deleterious effect on postharvest storage characteristics of fruit stored at 0.5–1°C for 18 weeks; fruit from deficient vines were firmer but had slightly lower soluble solids than fruit from control vines. Although deficiency symptoms were first observed on the basal leaves of the non-fruiting shoots mid season, indications of the impending deficiency could be established very early in the season using foliar analysis. Magnesium concentrations in youngest fully expanded leaves (YFEL) on the affected vines were less than 2.0 g kg−1 DM four weeks after budbreak and remained below this value for the rest of the season; concentrations in YFEL on unaffected vines did not decrease below this value and gradually increased after fruitset to 4.5 g kg−1 DM at harvest. To avert potential production losses, it is suggested that soluble magnesium fertilizers (containing at least 200 kg ha−1 Mg) should be broadcast early in the season if foliar magnesium concentrations less than 2.0 gkg−1 DM are measured four–six weeks after budbreak.Type of Medium: Electronic ResourceURL:
