The systematic position of the Middle Jurassic sauropod Lapparentosaurus madagascariensis is not fully understood due to a lack of useful anatomical detail. Despite many new bone fragments from the axial skeleton, post-cranial skeleton, and a hind limb having been previously unearthed, its systematic position has not yet been satisfactorily established. Although this Malagasy taxon is only recognised by two autapomorphies located in the scapula and coracoid, two features of the neural spine, which are reported here, provide additional information on the common autapomorphies shared with the British genus Cetiosaurus. A full description of the femur and neural spine helps to determine some aspects of its relationship to other similar taxa. Remains of Lapparentosaurus madagascariensis have been recovered from mixed facies that may have been deposited in a shallow water lagoon during a transgressive period in the Isallo IIIb subunit in the Majunga Basin.

We present some additional information to Acritagasyllis longichaetosus Lucas, San Martín & Sikorski 2010, the only representative of an enigmatic genus of Syllidae from subpolar areas off Norway, based on two newly found specimens and one male and another female stolons. The armature of the pharynx was incorrectly interpreted in the original description, having in fact a trepan instead of a single pharyngeal tooth as originally described. The reproductive stolons are herein described for the first time. With this new information we performed a maximum parsimony phylogenetic analysis that placed this genus within the subfamily Autolytinae, despite its peculiar morphological characteristics. For this reason, we propose a new diagnosis to the genus Acritagasyllis as well as a modified diagnosis of the subfamily Autolytinae.

The title of this talk is really just a different phrasing from one I have used at several IAU meetings on the subject of numbers and kinds of variables in globular clusters. To furnish this material, I have finished the Third Catalogue of Variables in Globular Clusters. Since many of you are coming to this Colloquium with new information, the Catalogue is in draft form with a request that corrections and additions be given me by October 2, after which the draft will go to the printer.The First Catalogue of Variables in Globular Clusters was published at this observatory in 1939 and the Second Catalogue in 1955. In 1966 appeared the excellent Catalogue of Variables South of Declination—29° by Fourcade, Laborde and Albarracin, with splendid large prints of identification charts.

Linguistic Influences

Hand gestures in face-to-face dialogue are symbolic acts, integrated with speech. Little is known about the factors that determine the physical form of these gestures. When the gesture depicts a previous nonsymbolic action, it obviously resembles this action; however, such gestures are not only noticeably different from the original action but, when they occur in a series, are different from each other. This paper presents an experiment with two separate analyses (one quantitative, one qualitative) testing the hypothesis that the immediate communicative function is a determinant of the symbolic form of the gesture. First, we manipulated whether the speaker was describing the previous action to an addressee who had done the same actions and therefore shared common ground or to one who had done different actions and therefore did not share common ground. The common ground gestures were judged to be significantly less complex, precise, or informative than the latter, a finding similar to the effects of common ground on words. In the qualitative analysis, we used the given versus new principle to analyze a series of gestures about the same actions by the same speaker. The speaker emphasized the new information in each gesture by making it larger, clearer, etc. When this information became given, a gesture for the same action became smaller or less precise, which is similar to findings for given versus new information in words. Thus the immediate communicative function (e.g., to convey information that is common ground or that is new) played a major role in determining the physical form of the gestures.

New Material

Abstract Xinjiangchelys oshanensis (Ye, 1973) was originally described as Plesiochelys oshanensisYe, 1973 from the Jurassic Upper Lufeng series of Eshan, Yunnan Province, China. The species was based on a single specimen (IVPP V4444), a damaged shell with articulated carapace and plastron. This species was later referred to as Xinjiangchelys? oshanensis and X. oshanensis respectively, but has never been revised and often overlooked in the studies of Asian Mesozoic turtles. In this paper, we provide the systematic revision of X. oshanensis (Ye, 1973) after new restoration of the specimen. Five additional shells from the Middle Jurassic Chuanjie Formation of Lufeng, Yunnan Province, China are referred to this species. Our study confirms the validity of the species and its assignment to the genus Xinjiangchelys. The study of the new material completes the shell morphology of X. oshanensis and provides additional information about its age.

Thousands of people worldwide suffer from injuries in the peripheral nerve and deal daily with the resulting physiological and functional deficits. Recent advances in this field are still insufficient to guarantee effective outcomes, and the development of new and effective therapeutic options requires the use of valid preclinical models that effectively replicate the characteristics and challenges associated with these injuries in humans. In this study, we established a sheep model for common peroneal nerve injuries that can be applied in preclinical research with the advantages associated with the use of large animal models. In an integrative way, this article includes a detailed description of the anatomy and functionality of the peripheral nerves of sheep’s hind limb, the surgical protocol for accessing the common peroneal nerve, the induction of different types of nerve damage and the application of possible therapeutic options. A neurological exam protocol directed to the common peroneal nerve was also established, allowing to identify the changes and deficits related with the nerve injury and to evaluate the functional progression over time. Finally, a preliminary stereological study was carried out to establish control values for the healthy peroneal common nerves of this model and to identify preliminary differences between therapeutic methods. The ultimate goal is to demonstrate that sheep is a valid model of peripheral nerve injury to be used in pre-clinical and translational works and to evaluate the efficacy and safety of nerve injury therapeutic options before its clinical application in human and veterinary patients.

This short (179 pages), well-composed text includes a presentation of the anatomy, hemodynamic characteristics, and surgical management of five congenital cardiovascular abnormalities. Although not much in the way of new information is offered, the material is easy to read and is followed by an excellent bibliography. Chapters dealing with patent ductus arteriosus, coarctation, atrial and ventricular septal defects, and tetralogy of Fallot comprise the materials covered by the text. With certain exceptions, for instance, the routine use of chloramphenicol as a postoperative antibiotic, the discussion of the surgical treatment and postoperative management of these anomalies is very well done.

The aim of this study was to investigate the variations as well as the length of A. cystica and its branches in pigs using corrosion casting method with the self-polymerising resin Duracryl® Plus. The method included several steps: hepatectomy, precasting treatment, injection of Duracryl, polymerisation of casting medium, corrosive treatment, cleaning of the corrosion casts, air-drying and preservation of casts. The livers were collected from 12 male 6-month-old pigs (crossbred Landrace×Danube White). With regards to the beginning of A. cystica, 4 variations were observed and grouped as follows: variation A  A. cystica detached from R. dexter medialis, together with R. quadratus (variation A1), or alone (variation A2); variation B1 – A. cystica originated from A. gastroduodenalis, or was a branch of the common trunk (R. dexter) (variation B2). The metric data were processed by GraphPad Prism 6 for Windows. Clinically relevant relations between А. сystica, Ductus cysticus, A. celiaca and R. sinister also were described. The new information re-ceived about the blood supply of the gallbladder would contribute to the understanding of the etiology of postoperative complications as a result of surgical interventions in this location and for their prevention.

AbstractFuture fully digital surgical visualization systems enable a wide range of new options. Caused by optomechanical limitations a main disadvantage of today’s surgical microscopes is their incapability of providing arbitrary perspectives to more than two observers. In a fully digital microscopic system, multiple arbitrary views can be generated from a 3D reconstruction. Modern surgical microscopes allow replacing the eyepieces by cameras in order to record stereoscopic videos. A reconstruction from these videos can only contain the amount of detail the recording camera system gathers from the scene. Therefore, covered surfaces can result in a faulty reconstruction for deviating stereoscopic perspectives. By adding cameras recording the object from different angles, additional information of the scene is acquired, allowing to improve the reconstruction. Our approach is to use a fixed four-camera setup as a front-end system to capture enhanced 3D topography of a pseudo-surgical scene. This experimental setup would provide images for the reconstruction algorithms and generation of multiple observing stereo perspectives. The concept of the designed setup is based on the common main objective (CMO) principle of current surgical microscopes. These systems are well established and optically mature. Furthermore, the CMO principle allows a more compact design and a lowered effort in calibration than cameras with separate optics. Behind the CMO four pupils separate the four channels which are recorded by one camera each. The designed system captures an area of approximately 28mm × 28mm with four cameras. Thus, allowing to process images of 6 different stereo perspectives. In order to verify the setup, it is modelled in silico. It can be used in further studies to test algorithms for 3D reconstruction from up to four perspectives and provide information about the impact of additionally recorded perspectives on the enhancement of a reconstruction.
