Saxonagrion minutus nov. gen. et sp., the oldest damselfly from the Upper Permian of France (Odonatoptera, Panodonata, Saxonagrionidae nov. fam.)
1999
Abstract Saxonagrion minutus nov. gen. et sp. was found in the Saxonian (Salagou Formation) of the Lodeve basin. It is the oldest and the first record of the modern infra-order Panodonata in the Palaezoic (Upper Permian of France). The present discovery supports the hypothesis concerning the persistance of many groups of Odonatoptera through the Permo-Triassic boundary.
Ichnocoenoses à Isopodichnus furcosus nov. ichnosp. dans le Permien du Bassin de Lodève (Massif Central, France)
1994
Resume Une nouvelle ichnoespece Isopodichnus furcosus est decrite. Elle represente des traces de repos faites probablement par des Branchiopodes notostraces. Frequente dans les formations de Rabejac et du Salagou du bassin de Lodeve, elle est caracterisee par l'existence de structures paires generalement bifides, parfois trifides. Celles-ci pourraient correspondre a l'empreinte des premiers appendices thoraciques, longs et ramifies chez les Triopsides ou Apodides a qui est attribuee Isopodichnus furcosus nov. ichnosp. La presence de niveaux a Isopodichnus furcosus nov. ichnosp. dans les formations rouges supraconglomeratiques de la serie permienne renforce la these du developpement de l'ari…
Endodontic management of single rooted immature mandibular second molar with single canal using MTA and platelet-rich fibrin membrane barrier: A case…
2011
An immature tooth with pulpal necrosis and periapical pathology imposes a great difficulty to the endodontists. Endodontic treatment options for such teeth consist of conventional apexification procedure with and without apical barriers. Various materials have been tried as apical matrix in the past. This article demonstrates the newer concept of using platelet rich fibrin membrane as an apical matrix barrier for stabilization of MTA in root end apexification procedure. Platelet Rich Fibrin is an autologous fibrin matrix containing a large quantity of platelet and leukocyte cytokines, which enhance healing by release of growth factors. This case report represents successful management of a …
The Effectiveness of LDOCE Definitions for Concrete and Abstract Nouns in Headword- and Picture-Identification Tasks
2021
Abstract LDOCE uses a defining vocabulary to make their definitions intelligible to the user. Critics claim this policy may result in imprecise definitions, something especially noticeable in certain concrete and abstract words that are difficult to define by a definition only. This paper examines to what extent LDOCE definitions of such words help learners identify the objects and words being defined. In our experiment on 381 learners of English as a foreign language, three groups of participants viewed different definition types: simplified definitions of LDOCE, unsimplified definitions of MWC, and definitions written in the learners’ mother tongue (UDPL/TR). The results show that the LDO…
Is the Erich arch bar the best intermaxillary fixation method in maxillofacial fractures? : a systematic review
2015
Background Intermaxillary fixation is used to achieve proper occlusion during and after oral and maxillofacial fracture surgery. The aim of this systematic review was to compare Erich arch bar fixation with other intermaxillary fixation methods in terms of the operating time, safety during installation, oral health maintenance and occlusal stability. Material and Methods An electronic online search was conducted of the Scirus, PubMed, Ovid, Cochrane Library and VHL databases. A clinical trial dating from the inception of the data bases until August 2013 was selected. Studies that compared Erich arch bars with other intermaxillary fixation methods in patients older than 18 years-old were inc…
Proximal Tibiofibular Joint Reconstruction With Autogenous Semitendinosus Tendon Graft
2013
Isolated and chronic anterolateral instability of the proximal tibiofibular joint (TFJ) is an uncommon condition, generally linked to an unrecognized or unhealed dislocation of the TFJ. Clinically, abnormal anterior movement of the head of the fibula is detected. In acute injuries conservative management should be preferred, whereas surgical treatment have been advocated in patients with chronic TFJ instability. Authors describe a new surgical reconstruction technique for chronic instability of the proximal TFJ using an autogenous semitendinosus tendon. The graft is passed through fibular and tibia tunnels and fixed with 2 interference screws. The tibial tunnel is reamed from the posterolat…
Immediate non-submerged implants with laser-microtextured collar placed in the inter-radicular septum of mandibular molar extraction sockets associat…
2019
Background The aim of the present study was to radiographically evaluate the vertical socket walls changes, and the peri-implant marginal bone remodelling, and clinicallly the soft tissues conditions around the non-submerged single implants placed into the inter radicular septum of mandibular molar sockets, associated with a collagen membrane, after 3 years of loading. Material and Methods Thirty patients underwent to placement of a non-submerged implants with a laser-microtextured collar into the inter radicular septum of mandibular molar fresh extraction sockets. A collagen membrane and the mucoperiosteal flap were adapted around the neck of the implants, leaving the laser-microtextured c…
Is work engagement related to healthy cardiac autonomic activity? Evidence from a field study among Finnish women workers
2012
The present study investigated whether work engagement is related to and can explain healthy cardiac autonomic activity as indicated by decreased heart rate (HR; i.e., sympathetic and parasympathetic activity) and increased high-frequency power (HFP) of heart rate variability (i.e., parasympathetic activity). A total of 30 healthy Finnish female cleaning workers underwent an ambulatory monitoring period of two nights and two regular workdays, and mean values of work period HR and HFP were utilized as dependent variables. Correlations revealed that work engagement was, as hypothesized, negatively related to HR and positively to HFP. Furthermore, in hierarchical linear regression analysis, wo…

Tomographic study of Jaw bone changes in patients with bisphosphonate-related osteonecrosis
2020
Background Bisphosphonates (BP) are synthetic pyrophosphate-like substances with antiresorptive properties and specifically affect osteoclastic activity. In 2007, the American Association of Oral and Maxillofacial Surgeons (AAOMS) defined diagnostic criteria for Osteonecrosis of the Jaws Associated with Bisphosponates (BRONJ). BRONJ is mainly diagnosed by clinical features, but the detection of early bone changes by imaging may help prevent and better understand the disease. The objective of this study was to evaluate maxillary changes in CBCT in patients using BP. Material and methods All included patients were diagnosed with osteonecrosis and received bisphosphonate drugs in the last ten …
