Cryopreservation of Hazelnut (Corylus avellana L.) Axillary Buds from In Vitro Shoots Using the Droplet Vitrification Method
2021
Cryopreservation by droplet vitrification was applied to hazelnut (Corylus avellana L.). axillary buds of the Italian cultivated variety Tonda Gentile Romana, which were collected from in vitro growing shoots, immersed in ice cooled PVS2 or PVS3 for 60 or 90 min, then transferred to a droplet of vitrification solution, placed on a strip of aluminium foil, and plunged into liquid nitrogen (LN). Additionally, the effect on the recovery of the mother plant after cryopreservation was evaluated, following a cold pre-treatment at 4 °C for 3 months. The highest regrowth percentage (56.7%) was obtained after applying PVS3 for 60 min, while the application of PVS2 for the same amount of time reduced…
Basilar Invagination, Bone Regrowth, Chiari malformation, Clivus, Odontoid Process, Transoral Odontoidectomy
2014
Purpose: Transoral odontoidectomy followed by occipito-cervical fixation is a widely used approach to relieve ventral compressions at the craniovertebral junction (CVJ). Despite the large amount of literature on this approach and its complications, no previous reports of odontoid process and clival regeneration following transoral odontoidectomy are present in the English literature. Methods: We report the case of odontoid process and clival regeneration following transoral odontoidectomy. Results: A 7 year-old boy presented with symptoms of brainstem and upper cervical spinal cord compression due to a complex malformation at the CVJ including a basilar invagination with Chiari malformation…
Effects of biomass, age and functional traits on regrowth of arable weeds after cutting
2008
Conference: 24th German Conference on Weed Biology and Weed ControlLocation: Stuttgart Hohenheim, GERMANYDate: MAR 04-06, 2008; International audience; In sown field margin stripes or pluriannual forage crops, arable weeds are exposed to high competition and regular mowing or hay cutting, to which they may react very differently. A greenhouse experiment permitted to understand some key factors shaping the ability of common arable weeds and forage crops to grow after such cuttings. Even without competition, cutting shoots at 5cm height reduced biomass production of all 10 species studied, but 6 annual broadleaf weeds were much more affected than 2 perennial forage crops (Dactylis, Medicago) …
Cryopreservation of Italian cultivars of hazelnut
2021
The present study was performed to optimise the cryopreservation protocol in Italian cultivars of Corylus avellana L. Lateral buds excised from in vitro grown plantlets of ‘Tonda Gentile Romana’ (TGR) and ‘Montebello’ (MB) were cryopreserved by the encapsulation-dehydration technique. The effect of dehydration of beads with sucrose (0.5, 0.75 or 1 M) for 1 or 3 days, of desiccation with silica gel for 6 or 8 h and of application of two cytokinins (N6-benzyladenine or meta-Topolin) in the regrowth phase was evaluated. The highest regrowth was obtained dehydrating alginate beads with 0.75 M sucrose applied for 1 day and with desiccation for 8 h with silica gel in both cultivars. On the other …

Effects of two essential oil mouthrinses on 4-day supragingival plaque regrowth: A randomized cross-over study
2013
Purpose: To investigate the plaque inhibiting effects of two commercially available mouthrinses containing essential oils (EO). Both products contained the same concentration of EO, but one of them did not contain ethanol. Methods: The study was an observer-masked, randomized, 4 × 4 Latin square cross-over design, balanced for carryover effects, involving 12 participants in a 4-day plaque regrowth model. A 0.12% chlorhexidine (CHX) rinse and a saline solution served as positive and negative controls, respectively. On Day 1, subjects received professional prophylaxis, suspended oral hygiene measures, and commenced rinsing with their allocated rinses. On Day 5, subjects were scored for disclo…

Diversifying crop rotations with temporary grasslands: potentials for weed management and farmland biodiversity
2010
Fruchtfolgen können dazu dienen, die kontinuierliche Selektion von Unkrautarten zu verhindern, die an eine bestimmte Kultur angepasst sind. Dies könnte dem Unkrautmanagement, der Einsparung von Herbiziden, und der Biodiversität dienen. Heutige, sehr einfache Furchtfolgen könnten durch mehrjährige Futterkulturen diversifiziert werden. Die Einflüsse solcher mehrjähriger Kulturen auf Unkräuter wurden in vier Ansätzen untersucht : 1) Vegetationsaufnahmen auf 632 Feldern in Westfrankreich zeigten, dass die Unkrautzusammensetzung zwischen mehrjährigen Futterkulturen und einjährigen Kulturen stark variiert. Der Vergleich von Feldern vor, während und nach mehrjährigen Futterkulturen legte nahe, das…
