    Description / Table of Contents: Hintergrund: Zahlreiche Hautveränderungen, die von Patienten als kosmetisch störend empfunden werden, manifestieren sich in periokulären Hautarealen. Während konventionelle Methoden wie die Exzision, die Elektrokauterisierung und die Kryotherapie oft nur unbefriedigende Ergebnisse bei der Behandlung solcher Hautveränderungen erbrachten, stehen zur Zeit vor allem Lasersysteme im Mittelpunkt des Interesses. Patienten und Methoden: 104 Patienten mit periokulären Hautveränderungen (Falten, Xanthelasmen, Syringome) wurden mit dem Erbium:YAG-Laser behandelt. Dieser arbeitet mit einer Wellenlänge von 2940 nm, einer Pulsbreite von 0,350 ms und einer Pulsenergie von 0,1–1,7 Joules. Ergebnisse: Der Erbium:YAG-Laser gewährleistet durch seine extrem kurze Impulsdauer eine narbenfreie, athermische Feinstablation sehr dünner Hautschichten mit Minimierung der Schäden in der Umgebung der behandelten Hautareale. Bei allen behandelten Patienten konnte ein ansprechendes kosmetisches Ergebnis erzielt werden. Schlußfolgerung: Wir sehen in der Anwendung des Erbium:YAG-Laser bei richtiger Vorgehensweise eine schonende und effektive neue Methode zur Behandlung verschiedener periokulärer Gesichtshautveränderungen.
    Notes: Introduction: A great number of cosmetically disturbing, cutaneous lesions are localized in the periocular region. While various approaches for treatment such as excision, electrocauterization or cryosurgery often show unsatisfactory results, the use of laser technology is of increasing interest. Material and methods: A total of 104 patients with different cutaneous periorbital lesions (wrinkles, xanthelasma, syringoma) were treated with a new erbium:YAG laser system (wavelength 2940 nm, pulse duration 0,350 ms and pulse energy 0,1–1,7 Joules), which works on the principle of vaporization. Results: The erbium:YAG laser allows athermic ablation of very thin skin layers without scarring and with minimal lateral thermal injury due an extremely short pulse duration. Periorbital lesions can be treated effectively by erbium:YAG laser, and good to excellent cosmetic results can be obtained. Conclusions: The use of pulsed erbium: YAG laser is an effective and promising new method for treatment of different superficial periorbital cutaneous lesions.

    Description / Table of Contents: Summary The erbium:YAG laser (wavelength 2940 nm; pulse duration 0.350 ms; pulse energy 0.1–1.7 J) allows vaporization of very thin skin layers without scarring and minimal lateral thermal injury due to an extremely short pulse duration. It permits exact ablation of relatively large areas of facial skin. We report our results with 216 patients following treatment for different facial lesions (facial wrinkles, acne scars, syringomas, and circumscribed sebaceous gland hyperplasia) using a new erbium:YAG laser system. Good-to-excellent cosmetic results were obtained in these patients. Our findings show that the erbium:YAG laser is an elegant and promising new method for the treatment of facial lesions.
    Notes: Zusammenfassung Der Erbium:YAG-Laser (2940 nm Wellenlänge; 0,350 ms Pulsbreite; 0,1-1,7 J Pulsenergie) gewährleistet durch seine extrem kurze Impulsdauer eine narbenfreie Ablation sehr dünner Hautschichten mit Minimierung thermisch bedingter Schäden in der Umgebung der behandelten Hautareale. Er erlaubt ein kontolliertes, exaktes Arbeiten und ermöglicht eine großflächige Behandlung der Haut im Gesichtsbereich. Wir berichten über unsere Ergebnisse an 216 Patienten, die wegen verschiedener störender Hautveränderungen im Gesichtsbereich (Hautfältchen, Aknenarben, Syringome, Talgdrüsenhyperplasien) mit dem Erbium:YAG-Laser behandelt wurden und gute bis sehr gute kosmetische Ergebnisse nach der Laserbehandlung zeigten. Wir sehen in der Anwendung des Erbium:YAG-Laser eine elegante und vielversprechende neue Methode zur Behandlung verschiedener Gesichtshautveränderungen.

    Notes: Summary A quadrilateral continuum-basedC 0 shell element is presented, which relies on extensible director kinematics and incorporates unmodified three-dimensional constitutive models. The shell element is developed from the nonlinear enhanced assumed strain (EAS) method advocated by Sino & Armero [1] and formulated in curvilinear coordinates. Here, the EAS-expansion of the material displacement gradient leads to the local interpretation of enhanced covariant base vectors that are superposed on the compatible covariant base vectors. Two expansions of the enhanced covariant base vectors are given: first an extension of the underlying single extensible shell kinematic and second an improvement of the membrane part of the bilinear element. Furthermore, two assumed strain modifications of the compatible covariant strains are introduced such that the element performs well even in the case of very thin shells.

    Notes: Summary A sarcoplasmic calcium-binding protein (SCP) has been purified from the muscle of the protochordate Amphioxus and shown to be more similar to invertebrate SCP's than to their counterpart found in vertebrates, i.e. parvalbumins. The Amphioxus protein has a pI of 4.9, is rich in tyrosine and tryptophan, has a molecular weight of 22,000 and binds strongly 2Ca2+ with a pK of 7.88. Magnesium competes with calcium for only one of the two metal-binding sites and induces positive cooperativity in Ca2+ binding. In cyclostome muscle (lamprey and hagfish), no protein with high affinity for Ca2+ or Mg2+ could be found, irrespective of molecular weight. Instead, a protein with moderate affinity for Ca2+ (⩽105 m −1) was detected: it has a molecular weight of 60,000 and might be quite ubiquitous, as the presence of a similar protein has been reported both in red and white muscle of vertebrates such as chicken and rabbit.

    Notes: Summary Coelomocytes of the earthworm, Lumbricus terrestris, were studied by transmission electron microscopy. Four morphological cell types are distinguishable: lymphocytic coelomocytes, granulocytic coelomocytes, eleocytes (chloragogen cells), and inclusion-containing coelomocytes. Within these major categories, several distinct cell types differ and may represent developmental stages. The two types of lymphocytic coelomocytes are small with central nuclei and scanty cytoplasms. Two types of granulocytic coelomocytes differ greatly in shape and content; both have small dark-staining granules that resemble lysosomes. Electrocytes, derived from chloragogen tissue, contain a variety of granules, inclusions and vacuoles. Inclusion-containing coelomocytes appear as two types which may be immature and mature forms. Although these cells resemble those that have been referred to as erythroid cells in other invertebrates, the large inclusion bodies are apparently unrelated to hemoglobin; they can undergo morphologic transformation and be extruded by exocytosis. This information on lymphocytic, granulocytic and inclusion-containing coelomocytes is crucial to understanding more about cellular immunity in the earthworm.
