Identifier les Clausilies de France
Olivier Gargominy,Eike Neubert
MalaCo , 2011,
Abstract: To go beyond the reference collection for French continental molluscs available in Muséum national d'Histoire naturelle, we present here a close-up on the family Clausiliidae based on the same material. Identification keys are proposed in the form of decision tree and illustrations show shell details that are necessary to correctly identify species and subspecies in this complex and diversified land snail family.
New taxa of terrestrial molluscs from Turkey (Gastropoda, Pristilomatidae, Enidae, Hygromiidae, Helicidae)
Bur?in Gümüs,Eike Neubert
ZooKeys , 2012, DOI: 10.3897/zookeys.171.2273
Abstract: This paper reports on results of several collecting trips of the authors in Turkey. In the course of this research, a long-lasting question was addressed. It could be proven that the nominal species Bulimus frivaldskyi L. Pfeiffer, 1847 is closely related to Meijeriella canaliculata Bank, 1985, and thus this species is shifted from the genus Ena Turton, 1831, to the genus Meijeriella Bank, 1985. Meijeriella canaliculata Bank, 1985, could be recorded from Turkey for the first time. The nomenclatural situation of the species Euchondrus septemdentatus (Roth, 1839) vs. its replacement name Euchondrus borealis (Mousson, 1874) is discussed. A new arrangement of the species formely comprised in the genus Zebrina Held, 1837 is presented, and the genera Rhabdoena Kobelt & Moellendorff, 1902, and Leucomastus A. Wagner, 1927 are re-established. The following species and subspecies new to science could be described: Vitrea gostelii sp. n. (Pristilomatidae), Turanena demirsoyi sp. n., Euchondrus paucidentatus sp. n., Rhabdoena gostelii sp. n. (all Enidae), Metafruticicola kizildagensis sp. n. (Hygromiidae), and Assyriella thospitis menkhorsti ssp. n. (Helicidae). For several other species, new distribution records are listed.
The biodiversity of the terrestrial malacofauna of Turkey – status and perspectives
Bur?in Gümüs,Eike Neubert
ZooKeys , 2009, DOI: 10.3897/zookeys.31.169
Abstract: The status of knowledge of the terrestrial malacofauna of Turkey is briefly reviewed, and the perspectives for studies on the malacofauna of the country are discussed.
Sphincterochilidae from Tunisia, with a note on the subgenus Rima Pallary, 1910 (Gastropoda, Pulmonata)
Intidhar Abbes,Said Nouira,Eike Neubert
ZooKeys , 2011, DOI: 10.3897/zookeys.151.2264
Abstract: In order to establish an updated checklist of terrestrial gastropod from Tunisia, a revision of the species of Sphincterochilidae is presented, using bibliographic and museum records and the results of our own field work. As a result, only two species, Sphincterochila candidissima and S. tunetana, are accepted to occur in Tunisia, and their type specimens are illustrated. The study of the morphological characters of the genital organs of both species clarified their subgeneric affiliation. Comparison of S. tunetana with S. cariosa from Lebanon showed that the first has to be classified within the subgenus Albea, and the latter within Sphincterochila s. str.; the subgenus Rima Pallary, 1910 remains in the synonymy of Sphincterochila s. str. Bibliographic records of S. baetica and S. otthiana from Tunisia could not be confirmed, the latter probably lives close to the border with Algeria.
Sexual dimorphism in shells of Cochlostoma septemspirale (Caenogastropoda, Cyclophoroidea, Diplommatinidae, Cochlostomatinae)
Fabian Reichenbach,Hannes Baur,Eike Neubert
ZooKeys , 2012, DOI: 10.3897/zookeys.208.2869
Abstract: Sexual dimorphisms in shell-bearing snails expressed by characteristic traits of their respective shells would offer the possibility for a lot of studies about gender distribution in populations, species, etc. In this study, the seven main shell characters of the snail Cochlostoma septemspirale were measured in both sexes: (1) height and (2) width of the shell, (3) height and (4) width of the aperture, (5) width of the last whorl, (6) rib density on the last whorl, and (7) intensity of the reddish or brown pigments forming three bands over the shell. The variation of size and shape was explored with statistical methods adapted to principal components analysis (PCA) and linear discriminant analysis (LDA). In particular, we applied some multivariate morphometric tools for the analysis of ratios that have been developed only recently, that is, the PCA ratio spectrum, allometry ratio spectrum, and LDA ratio extractor. The overall separation of the two sexes was tested with LDA cross validation.The results show that there is a sexual dimorphism in the size and shape of shells. Females are more slender than males and are characterised by larger size, a slightly reduced aperture height but larger shell height and whorl width. Therefore they have a considerable larger shell volume (about one fifth) in the part above the aperture. Furthermore, the last whorl of females is slightly less strongly pigmented and mean rib density slightly higher. All characters overlap quite considerably between sexes. However, by using cross validation based on the 5 continuous shell characters more than 90% of the shells can be correctly assigned to each sex.
Biosimilar Epoetin Zeta in Nephrology: Effect of Injection Frequency on Weekly Dose  [PDF]
Gerhard Lonnemann, Eike Wrenger
International Journal of Clinical Medicine (IJCM) , 2012, DOI: 10.4236/ijcm.2012.37108
Abstract: Aim: This observational clinical study tested the effect of injection frequency of the biosimilar epoetin zeta on the weekly dose needed to maintain stable hemoglobin levels in chronic kidney diseases (CKD) patients on intermittent high-flux hemodialysis (HD). Patients and Methods: CKD patients (n = 33) on regular HD therapy 3 times a week were treated for 18 months with epoetin zeta i.v. The hemoglobin levels, the weekly dose as well as the injection frequency of epoetin zeta were monitored at least every two weeks. Patients were followed in three time periods: 1) extended follow-up (months 1 - 18); 2) intervention phase (months 19 - 21); and 3) post intervention observation phase (months 28 - 30). During extended follow-up the majority of patients (n = 21) received only one injection of epoetin zeta per week. During the intervention phase, injection frequency was increased to 3 injections per week in all patients accompanied by a reduction in weekly doses of approximately 20%

Abstract: I am happy to report on the latest activities from the SCMR Board of Trustees. We held our mid-year meeting in Philadelphia at the Airport Hotel. One of the key tasks of this Board meeting is to examine the 2011 scientific program to find and eliminate any weaknesses or risks. In addition, the work of the organization's committees is reported and reviewed, the platinum supporters and the Board have an open discussion, and the members of the Board review the management of the Society.2011 Program Chair Sven Plein MD and Abstract Chair Raymond Kwong MD have put a fantastic program together. There are a couple of new features this year. For PhDs there is a basic science preconference on pulse sequence design, a translational abstract track, extended poster viewing times and early morning sessions on basic cardiology. For Physicians there is a full parallel track with cases and how-to sessions as well as early morning sessions on basic physics. For congenital heart disease specialists there is a one-day preconference, and more cases and how-to sessions. Technologists will enjoy full access to the meeting and can join the cases and how-to sessions. All this, on top of the outstanding features of the previous conferences.We anticipate even more participants than the record meeting last year and believe that we have listened to and integrated the wishes of our membership and attendees. We are looking forward to a meeting in Europe with more European participants, speakers, and influence then ever. We also hope to strengthen our ties with France and welcome many French attendees. To improve the access to knowledge on CMR in France, a Wikipedia webpage has been developed in French (led by Mark Westwood MD and his French collaborators).The "Young Investigator Award" has been renamed to "Early Career Award" to clearly state that investigators who had a late start in CMR can also achieve this award.SCMR will again offer Regional Scholarships for the 2011 meeting.

Abstract: The year 2010 has started well for SCMR in many aspects. The 2010 Annual Scientific Sessions were a great success with 1138 participants, the highest ever for our Annual Meeting. Andrew Arai, MD as Programme Chair and Sven Plein, MD as Abstract Chair did a terrific job in putting together a sound scientific program with excellent posters, scientific presentations and invited talks. As a novelty, an additional track was introduced, featuring clinical cases for discussion, which was highly welcomed by the participants. We will try to strengthen these case-based sessions in our future meetings. We are looking forward to the next meeting February 3-6, 2011 in Nice, France and hope to be able to attract many known and unknown faces. SCMR has awarded five regional scholarships for the 2010 meeting. We will continue to do so for next year, further expand the scheme and also have an additional scholarship specifically for technologists starting in 2011. Please stay tuned to our web pages for details.I would like to highlight our award winners 2009/2010:Young Investigator Award Clinical: Tim Lockie - Division of Imaging Sciences, King's College London, UK for Detection of hemodynamically significant coronary stenoses with k-t SENSE-accelerated Myocardial Perfusion MR Imaging at 3.0 Tesla - a comparison with fractional flow reserveYoung Investigator Award Experimental: Andrew Flett - The Heart Hospital, London, UK for Equilibrium contrast MR for the measurement of diffuse myocardial fibrosis and Cameron Holloway - University of Oxford, UK for Normobaric hypoxia elevates free fatty acids and impairs cardiac energetics and diastolic function in normal human volunteers.Moderated Poster Clinical: Andreas Kumar - University of Calgary, Canada for Reperfusion hemorrhage is a marker for the severity of tissue injury in patients with acute ST-elevation myocardial infarctionModerated Poster Experimental: Ronald Beyers - University of Virginia, USA for Whole-heart T2-weighted (T2w) seq
