Mucocele in atypical localization – a case report

The article describes a case of an oral mucocele of the palatoglossal arch in 5 y.o. patient, treated by conventional surgical excision of the lesion in general anesthesia

Removal of necrotic alveolar part of mandible with CGF (Concentrated Growth Factors) application into a post-operative bone defect – a case report

Usage of platelet concentrate is an interesting clinical option for enhancement of healing tissue. One of them – Concentrated Growth Factors (CGF) is produced by processing blood samples with a special centrifuge device. It is proven that this material contains high concentration of growth factors and CD34+ cells which have anti-inflammatory properties and ability to stimulate proliferation and differentiation of connective tissue cells and angiogenesis. The following article presents a case of 70-year-old-patient who underwent the augmentation of the post-operative bone defect with CGF after removal of necrotic alveolar part of the mandible

Preparation and dental surgical procedure in patients with osteogenesis imperfecta on the example of a 15-year-old patient with difficult tooth 38 eruption

The article presents a case of surgical extraction of a completely impacted tooth 38 under general anesthesia in a 15-year-old female patient with osteogenesis imperfecta, type III A

Extraction of totally impacted lower third molar with CGF (concentrated growth factors) application into a post-extraction bone defect – a case report

Concentrated Growth Factors (CGF) are obtained after blood collecting and its centrifuging. As an autogenic material it gains an advantage over xenogeneic materials used in regenerative procedures. Due to high concentration of growth factors and CD34+ cells in such a small volume, CGF promotes tissue regeneration. The following the article presents a case of 32-year-old-patient who underwent the augmentation of the post-extraction bone defect with CGF after the extraction of totally impacted lower third molar. Reduction of post-operative complications was observed

EB Ford revisited: assessing the long-term stability of wing-spot patterns and population genetic structure of the meadow brown butterfly on the Isles of Scilly

This is the author accepted manuscript. The final version is available from the publisher via the DOI in this record.Data files of wing spot sizes and AFLP genotypes available from the Dryad Digital Repository: http://dx.doi.org/10.5061/dryad.j7v42.Understanding selection in the wild remains a major aim of evolutionary ecology and work by Ford and colleagues on the meadow brown butterfly Maniola jurtina did much to ignite this agenda. A great deal of their work was conducted during the 1950s on the Isles of Scilly. They documented island-specific wing-spot patterns that remained consistent over about a decade, but patterns on some islands changed after environmental perturbation. It was suggested that these wing-spot patterns reflected island-specific selection and that there was little migration between islands. However, genetic studies to test the underlying assumption of restricted migration are lacking and it is also unknown whether the originally described wing-spot patterns have persisted over time. We therefore collected female butterflies from five of Ford's original study locations, including three large islands (St Mary's, St Martin's and Tresco) and two small islands (Tean and St Helen's). Wing-spot patterns had not changed appreciably over time on three of the islands (two large and one small), but were significantly different on the other two. Furthermore, analysis of 176 amplified fragment length polymorphisms revealed significant genome-wide differentiation among the five islands. Our findings are consistent with Ford's conclusions that despite the close proximity of these islands, there is restricted gene flow among them.Heredity advance online publication, 2 November 2016; doi:10.1038/hdy.2016.94.We thank the Genetics Society for a fieldwork grant (to DJH) that funded the collection trip and DJH thanks Mike Johnson for sparking interest in this area.

Consequences of frugivore‐mediated seed dispersal for the spatial and genetic structures of a neotropical palm

The idiosyncratic behaviours of seed dispersers are important contributors to plant spatial associations and genetic structures. In this study, we used a combination of field, molecular and spatial studies to examine the connections between seed dispersal and the spatial and genetic structures of a dominant neotropical palm Attalea phalerata. Field observation and genetic parentage analysis both indicated that the majority of A. phalerata seeds were dispersed locally over short distances (10 m) from maternal palms. Seedlings were also spatially aggregated with juveniles. These patterns are probably associated with the dispersal of seeds by rodents and the survival of recruits at specific microsites or neighbourhoods over successive fruiting periods. Our cross‐cohort analyses found palms in older cohorts and cohort pairs were associated with a lower proportion of offspring and sibling neighbours and exhibited weaker spatial and genetic structures. Such patterns are consistent with increased distance‐ and density‐dependent mortality over time among palms dispersed near maternal palms or siblings. The integrative approaches used for this study allowed us to infer the importance of seed dispersal activities in maintaining the aggregated distribution and significant genetic structures among A. phalerata palms. We further conclude that distance‐ and density‐dependent mortality is a key postdispersal process regulating this palm population.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/90113/1/j.1365-294X.2011.05425.x.pd
