TY - JOUR A1 - Mahsberg, Dieter T1 - Contact chemoreception of prey in hunting scorpions N2 - Scorpions commonly are assumed to hunt on living prey. But under laboratory conditions they also respond very sensitively to dead insects lying on the substrate. In many cases the motionless prey is seized and consumed. It was investigated how this behavior can be elicited. The buthid scorpions Androctonus australis (L.) and Buthus occitanus (Am.) not only find motionless prey again which was stung but managed to escape before dying: They also respond to extracts of the cuticle of prey insects. After touching prey marks' either with the tips of the chelae fingers or the tarsi of the walking legs or the pectine organs specific responses (searching, seizing, feeding) are released at a high rate. Behavioral experiments demonstrate for the first time the chemosensitivity of the pectine organs for which only mechanosensitivity had been proofed formerly. Mechanical as well as contact chemical stimulation of these organs cause scorpions to orient towards the stimulus source which is grasped, retained and consumed or rejected depending on its quality. The probably responsible chemosensitive receptors are already described in the literature. The possible adaptive value and the biological significance of contact chemoreception in prey catching and in other aspects of the life of scorpions is discussed.

Studies on groups of psychiatric patients and control subjects are reported in which nonverbal behavior is analyzed from videotaped dialogues. Using a quantitative approach, results on facial behavior, speech, and gaze are described, which shed light on the expressive and communicative functions of nonverbal behavior. From longitudinal observations on depressed patients it emerged that individualspecific associations have to be taken into account for the relationship between expressive behavior and mood changes. The predominance of facial behavior in the speaker role of an individual found in patients and control groups points to the integrated communicative function of the verbal and nonverbal elements. However, recovered schizophrenic patients exhibited a dissociation of these elements. Implications for our understanding of nonverbal communications are discussed.

A1 - Christen, A. A1 - Hacker, Jörg T1 - Comparative therapeutic activities of Ciprofloxacin, Amoxicillin, Ceftriaxone and Cotrimoxazole in a new model of experimental infection with Escherichia coli N2 - A new mouse model for systemic infection with Escherichia coli is presented. Whereas in other models 107_108 bacteria have to be injected into an animal to induce toxic effects resulting in death within 24 hours, now, only 103_104 bacteria of an appropriate strain are required to produce a genuine infection characterized by an increase in the bacterial load over several days. The quantitative determination of bacterial counts per liver allows a more sensitive measurement than recording death rates. Furthermore, few animals are required for a definite result in contrast to the LDso determination of other models. The salient point regarding this new model is that conditioning of animals has to be achieved by incorporating the inoculum into agar which is injected subcutaneously. The resulting infection is completely dependent on the E. colicondistrain used. Whereas a hemolytic, uropathogenic strain is so virulent that an overwhelming infection develops within 48 hours after the injection of 103 bacterial cells, a non-hemolytic variant of this strain is completely avirulent, being unable to multiply in spite of the potentiating agar. The hemolytic E. coli strain ATCC 25922 is intermediate in virulence. The bacterial counts per liver increase steadily until death occurs five to seven days after the injection of 104 bacteria. This bacterial infection can be therapeutically influenced by daily treatment with various drugs. Ciprofloxacin, ceftriaxone and co-trimoxazole are able to cure the infection, whereas amoxicillin given orally is only moderately active against this ATCC strain, which is relatively resistant to amoxicillin. N2 - Vergleichende therapeutische Aktivitiiten von Ciprof/oxacin, Amoxicillin, Ceftriaxon und Co-trimoxazol in einem neuen Versuchsmodell fur die experimentelle Infektion mit Escherichia coli. Ein neues Mausmodell fur eine systemische Infektion mit Escherichia coli wird vorgestellt. In anderen Infektionsmodellen mussen 107_108 E. coli pro Maus injiziert werden, was zu einer Intoxikation fUhrt, so daB die Tiere innerhalb von 24 Stunden sterben. In diesem neuen Modell wird eine echte Infektion mit nur 103-104 Bakterien gesetzt, und es folgt dann uber mehrere Tage hinweg eine deutliche Vermehrung der Erreger. Diese kann exakt quantitativ durch die Bestimmung der Keimzahlen in der Leber kontrolliert werden, was eine viel empfindlichere Methode darstellt als die Feststellung von Mortalitatsraten. Weiterhin werden dabei weitaus weniger Mause benotigt, urn eine stichhaltige Aussage zu machen, als fUr eine Bestimmung der LDso erforderlich sind. Der entscheidende Punkt dieses neuen Modells ist, daB die Infektion mit den niedrigen Keimzahlen gebahnt werden muB. Diesgeschieht dadurch, daB das Inokulum in verflussigtem Agar suspendiert wird, bevor es subkutan injiziert wird. Der Infektionsverlauf ist wesentlich abhiingig von der Natur des verwendeten E. coli-Stammes. Wahrend z. B. ein hamolytischer, uropathogener Stamm so virulent ist, daB die Tiere einer fulminanten Infektion nach Injektion von nur 103 Keimen erliegen, ist eine nicht-hamolytische Mutante dieses Stammes vollig avirulent und kann sich selbst trotz der Beigabe von Agar nicht vermehren. Der hamolytische Stamm E. coli A TCC 25922 ist bezuglich seiner Virulenz intermediar, d. h. nach Injektion von 104 Bakterien nimmt die Keimzahl pro Leber standig zu und die Tiere sterben nach funf bis sieben Tagen an dieser Infektion. Gerade dieser Infektionsverlauf kann durch tagliche Verabreichung von Chemotherapeutika beeinfluBt weT-den. Ciprofloxacin, Ceftriaxon und Co-trimoxazol sind in der Lage, eine Ausheilung zu erzielen. Amoxicillin hat nach oraler Gabe nur eine maBige Wirkung aut die Infektion mit diesem ATCC-Stamm, der auch gegen Amoxicillin relativ resistent ist.

Due to the unusual mild conditions of aggregation the intermediate formation of the double bonded species Cp(CO)\(_2\)M = AsMe\(_2\) (2a, b) is postulated.

This technique proved to be very sensitive and entirely specific. DNA could be demonstrated in four different compartments (nucleus, nucleomorph, plastid, and mitochondrion). Within the plastid, DNA is concentrated in stroma regions that are localized preferentially around the center of the organelle. The mitochondrion contains several isolated DNA-containing regions (nucleoids). Within the nucleus, most of the DNA is localized in the 'condensed' chromatin. DNA was also detectable in small areas of the nucleolus, whereas the interchromatin space of the nucleus appeared almost devoid of DNA. Within the nucleomorph, DNA is distributed inhomogeneously in the matrix. DNA could furthermore be detected in restricted areas of the 'fibrillogranular body' of the nucleomorph, resembling the situation encountered in the nucleol us. The presence of DNA and its characteristic distribution in the nucleomorph provide additional, strong evidence in favour of the interpretation of that organelle as the residual nucleus of a eukaryotic endosymbiont in Cryptomonas.

T1 - Immunolocalization and partial characterization of a nucleolar autoantigen (PM-Scl) associated with polymyositis / scleroderma overlap syndromes. N2 - Precipitating anti-PM-Sel antibodies are present in sera from patients with polymyositis. scleroderma. and polymyositis/scleroderma overlap syndromes. By indirect immunofluorescence microscopy. anti-PM-Scl antibodies stained the nucleolus in cells of different tissues and species. suggesting that the antigen is highly conserved. By electron microscopy, anti-PM-Scl antibodies reacted primarily with the granular component of the nuc1eolus. Drugs that inhibit rRNA synthesis had a marked effect on the expression of PM-Scl antigen. In actinomycin D-treated cells, immunofluorescence staining by anti-PM-Scl was signüicantly reduced with residual staining restricted to the granular regions of nuc1eoli. Treatment with 5,6-dichloro-beta-D- ribofuranosylbenzimidazole (DRB) also selectively reduced nuc1eolar staining. On a molecular level, anti-PM-Sel antibodies precipitated 11 polypeptides with molecular weights (Mr) ranging from 110,000 to 20,000. The Mr 80,000 and 20.000 polypeptides were phosphorylated. Evidence suggests that the PM-Scl antigen complex may be related to a prerlbosomal particle.
