A stereotactic device for rabbits based on mandibular and cranial landmarks
2008
✓ The authors have developed a stereotactic device for use in rabbits that uses the plane at the base of the mandible combined with cranial sutures as an anatomical reference. The device was developed for a study designed to evaluate catheters for infection prophylaxis, and this required the implantation of silicone catheters along a reproducible trajectory through the lateral ventricle. Cadaver and atlas studies demonstrated consistent spatial relationships between intracranial structures and the surface plane on which the animals were resting during the surgery. This plane is formed by the 2 mandibular angles and the mandibular tip. The authors developed a stainless steel stereotactic dev…
Density and biomass of smelt (Osmerus eperlanus) in five Finnish lakes
2005
Abstract Hydro-acoustic stock assessment and exploratory sampling with small mesh-sized trawls and seines have sometimes suggested that the importance of smelt (Osmerus eperlanus) in pelagic fish communities might be greater than sampling from commercial fishery and gillnetting indicate. We studied the proportion of smelt in the total fish density (fish ha−1) and biomass (kg ha−1) of pelagic fish with echo sounding and trawling in five southern boreal lakes. Fish density varied between 460 and 2000 fish ha−1 in the study lakes. Smelt and vendace (Coregonus albula) accounted for more than 95% of the exploratory trawl-catches. The total fish biomass in the study areas varied between 3 and 13 …
Etude expérimentale de l'incorporation du strontium et du magnésium dans les valves d'un ostracode d'eau douce, Herpetocypris brevicaudata (Crustacea…
1997
Resume L'etude geochimique des valves adultes et juveniles (stade 8) d'Herpetocypris brevicaudata, calcifiees en laboratoire, dans une eau portee a quatre temperatures maintenues constantes (12,4; 14,6; 19,8; 23,3 °C), a mis en evidence l'influence du processus de calcification sur l'incorporation du strontium et du magnesium, et a montre que la temperature de l'eau ne modifie pas la teneur en Mg des valves d'H. brevicaudata. Les coefficients de partition D(Sr) et D(Mg) sont determines pour la premiere fois pour cette espece: adulte: D(Sr) = 0,195 ± 0,013 et D(Mg) = 0,0171 ± 0,0018; juvenile: D(Sr) = 0,198 ± 0,009 et D(Mg) = 0,0208 ± 0,0008.
Comparative Analysis of Periodontal Pain According to the Type of Precision Orthodontic Appliances: Vestibular, Lingual and Aligners. A Prospective C…
2021
The objective of this prospective clinical study was to analyze the pain (intensity, location and type) that patients presented after the placement of different types of orthodontic appliances: conventional, low friction, lingual and aligners. The sample consisted of 120 patients divided into four groups: conventional (CON), low friction (LF), lingual (LO) and aligners (INV). The participants were given the Short-Form McGill Pain Questionnaire (Ortho-SF-MPQ), where they had to record the pain intensity (no pain, mild, moderate or intense) and the periodontal location at different time points, from the first 4 h to 7 days after the start of treatment. In all the study groups, the most freque…
Fossil representatives of the family Greenideidae (Hemiptera, Aphidoidea) from the Miocene of Europe
2002
Abstract Four new aphid species (Hemiptera, Aphidoidea, Greenideidae) are described on the basis of imprints in oil-shales from the Miocene of Europe (Rubielos de Mora, Spain; Vishnevaya Balka 〚Stavropol〛, Russia): Eutrichosiphum europaeum nov. sp., Greenidea hispanica nov. sp., Greenideoida (Pentatrichosiphum) turolensis nov. sp. and Mollitrichosiphum rubusensis nov. sp. All the taxa are placed within recent genera of the subfamily Greenideinae. Miocene representatives of this subfamily have been found in the south of Europe. Later changes of climatic conditions limited its geographic range to south-eastern Asia, where it is now represented by over 130 species of seven genera.
Lifelong exposure to low dose xeno-hormones in rats : multi-generational effects of xeno-hormone mixtures on taste preferences, maternal behavior, an…
2012
During the last decade, the issue of health-related endocrine disruptors (ED) has been extended to the toxicity of mixtures. The objective of this study was to define the effects of lifelong exposure to ED mixtures, at low doses defined as "non-harmful" by the authorities. In this aim, the effects of mixtures combining genistein, vinclozolin and bisphenol A, have been investigated in the rat by using an integrative and multi-generational experimental approach which takes into account maternal behavior, feeding behavior and development. Our results show that these mixtures could: a) reduce maternal behavior, b) change taste preferences (sweet, salty), c) affect the development from the in ut…
Gingival and submandibular lymph node metastasis of sigmoid colon adenocarcinoma
2010
Introduction: Metastatic tumors of oral and maxillofacial region compromise 1% of all malignant oral neoplasms. Most commonly affect the jaw bone and less commonly intraoral soft tissues. They originate mainly from primary tumors of lung, breast, colon-rectum, prostate and kidney. Case report: a 77 years old man with history of sigmoid colon adenocarcinoma and liver metastasis. Two years later of being free of disease, he presented with submandi- bular lymphadenopathy and a gingival mass in right upper jaw. Fine needle aspiration of the node and biopsy of the gingival mass were performed. The cytological smears showed cohesive cell groups on a necrotic background. Biopsy examination showed …
Results of isolated posterolateral corner reconstruction
2010
Abstract Background Isolated posterolateral corner (PLC) tears are relatively rare events. Various surgical techniques to treat posterolateral knee instability have been described; because surgical results are linked to cruciate reconstructions it has been difficult to date to define whether one surgical procedure has better prognosis than another. The goal of this study is to determine the clinical outcome of PLC reconstruction following fibular-based technique. Materials and methods We retrospectively evaluated a case series of patients who received isolated PLC reconstruction between March 2005 and January 2007. Ten patients were surgically treated for isolated injuries and were availabl…
What a New Model of Skeletal Homologies Tells Us About Asteroid Evolution1
2000
The Extraxial-Axial Theory (EAT) is applied to the body wall homologies of asteroids. Attempts to characterize major plate systems of asteroids as axial or extraxial, particularly those that are highly organized into series, can be problematic. However, the Optical Plate Rule (OPR) is instrumental in establishing that ambulacrals and terminals are axial. It is equally clear that the region aboral to the marginal frame is a part of the perforate extraxial body wall (with the possible exception of the centrodorsal, which is likely imperforate extraxial). Previously established EAT criteria, particularly those strongly rooted in the embryologically expressed boundary between axial and extraxia…
A new species of Tococladidae CARPENTER, 1966 from the Permian of France (Insecta: Archaeorthoptera)
2003
Abstract A new forewing venation pattern of the Tococladidae is proposed and the phylogenetic affinities of this family are discussed, based on Tococladus garrici nov. sp. This fossil comes from the Salagou Formation (Permian, Saxonian Group, Lodeve basin, France). The Tococladidae is assigned to the Archaeorthoptera BETHOUX and NEL, 2002 . The biostratigraphic implications of this discovery are briefly discussed, but it is still not possible to infer any definite conclusion about the age of this formation.
