    Notes: We show that small in-plane magnetization components in magnetic garnet films with perpendicular anisotropy can be imaged using nonlinear magneto-optical proximal probe microscopy, i.e., magnetization-induced second harmonic generation together with a scanning near-field optical microscope. A relationship exists between the in-plane magnetization domains we observed and the typical maze-like out-of-plane magnetization domains that are simultaneously imaged recording the linear Faraday effect. © 2000 American Institute of Physics.

    Notes: Reelin is an extracellular matrix protein secreted by a variety of cell types throughout the developing brain. The target cells for reelin express the cytoplasmic adapter protein Dab1, which binds to the reelin receptors VLDLR and ApoER2. In the present work, we have studied the localization of both receptors in developing mouse and human cortex, olfactory bulb and cerebellum. In mouse, some Cajal–Retzius cells express reelin and VLDLR; in humans, all the components of the signalling pathway (Reelin, Dab1, VLDLR and ApoER2) are present in subsets of Cajal–Retzius cells. In the mouse cortical plate, VLDLR and ApoER2 are present from E15 to postnatal stages; in human cortical plate they are most prominent at ≈ 20 gestational weeks. In mice, cerebellar Purkinje cells only express VLDLR whereas in humans they express both VLDLR and ApoER2. Mitral cells of the mouse olfactory bulb are ApoER2-positive and VLDLR-negative. In sum, the receptor expression patterns are similar in the human and mouse cortical plate but differ in Cajal–Retzius and Purkinje cells, which in humans express additional components of the reelin–Dab1 pathway.

    Notes: This paper reports the outcome evaluation of a gun safety video intervention. Guided largely by the extended parallel process model, the video, Bullet ‘Proof’ - The Case for Gun Safety' focuses primarily on (a) knowledge of 6 gun safety practices, (b) susceptibility to accidental gunshot injuries and death, severity of gunshot injuries, (d) response efficacy, and (e) self-efficacy. The video was shown to 175 individuals in 7 hunter safety classes and evaluated in a field experiment using a posttest-only control-group design with random assignment. Compared to the control group, the experimental group listed significantly more gun safety practices, perceived greater susceptibility to accidental gun injuries, perceived gun injuries to be more severe, and perceived greater response efficacy toward some of the recommended gun safety practices. Further, all of the recommended gun safety practices received high self-efficacy and behavioral intention ratings. Finally, the video itself scored high on all measured positive attributes, and low on all measured negative attributes.

    Notes: summary  The literature has documented a controversial discussion on the possible relationship of otogenous symptoms and craniomandibular dysfunction since the 1920s. Therefore, an investigation was conducted which consisted of two parts: a case study with population-based controls and a cross-sectional study. The aim of the first study was to screen a group of patients suffering from acute or chronic tinnitus for temporomandibular disorders (TMD) in comparison with a population-based group of volunteers without tinnitus. To this end, 30 patients (13 females and 17 males, age 18–71 years) suffering from acute hearing loss associated with tinnitus, isolated acute tinnitus, and chronically transient tinnitus were examined for symptoms of craniomandibular dysfunction. The results were compared with those of clinical functional analysis from 1907 subjects selected representatively and according to age distribution from the epidemiological ‘Study of Health in Pomerania’ (SHIP); the occurrence of tinnitus was ruled out in these control subjects. Statistical analysis was performed with Chi-square and Mann–Whitney U-tests. Sixty per cent of the tinnitus patients and 36·5% of the control subjects exhibited more than two symptoms of TMD (P = 0·004). Tinnitus patients had significantly more muscle palpation pain (P 〈 0·001), temporomandibular joint (TMJ) palpation pain (P 〈 0·001), and pain upon mouth opening (P 〈 0·001) than the general population group. No statistical differences were found in TMJ sounds, limitation of mandibular movement, or hypermobility of the TMJ. Furthermore, 4228 subjects of the population group examined in the epidemiological study were screened for co-factors of tinnitus with the help of a multivariate logistic regression model which was adjusted for gender, age, and a variety of anamnestic and examined data. Increased odds ratios (OR) were found for tenderness of the masticatory muscles (OR = 1·6 for one to three painful muscles and OR = 2·53 for four or more painful muscles), TMJ tenderness to dorsal cranial compression (OR = 2·99), listlessness (OR = 2·0) and frequent headache (OR = 1·84) A relationship between tinnitus and TMD was established in both examinations. Tinnitus patients seem to suffer especially from myofascial and TMJ pain. A screening for TMD should be included in the diagnostic survey for tinnitus patients.

    Notes: Zusammenfassung Für Myonen beiderlei Vorzeichens wird die Streuverteilung bei Quecksilberkernen im Energiebereich von etwa 30 MeV angegeben. Die Berechnung geschieht mit Hilfe eines auf dieDirac-Gleichungen zugeschnittenen WKB-Verfahrens, wobei dessen Anwendbarkeit jedoch nicht auf den hier interessierenden schwach relativistischen Energiebereich beschränkt ist. Die für die beiden Kernradien 1,2 · 10−13 ·A 1/3 cm und 1,4 · 1013 ·A 1/3 cm gefundenen Ergebnisse lassen es sinnvoll erscheinen die zum Problem der Größe des Kernradius ausgeführten Experimente durch Streuversuche mit Myonen zu ergänzen, falls es möglich wird in dem genannten Energiebereich mit ausreichender Teilchenstromdichte und Energiehomogenität zu experimentieren.

    Description / Table of Contents: Abstract Purpose. To compare the efficacy of trabeculotomy (TO) and that of goniotomy (GO) as a primary surgical procedure in congenital glaucoma. Patients and methods. We retrospectively analyzed 39 eyes of 22 children with congenital glaucoma who underwent TO with or without a small trabeculectomy. The results were compared to data on 34 eyes of 21 children who underwent GO for congenital glaucoma. Results. The mean preoperative intraocular pressure (IOP) was 28.2±6.7 mmHg in TO eyes and 31.0±7.9 mmHg in GO eyes. Mean IOP at the end of follow-up was 17.7±6.0 mHg in TO eyes and 18.9±9.1 mmHg in GO eyes. In 31 of 39 TO eyes (79.5%) and in 26 of 34 (76.5%) GO eyes the IOP was 21 mmHg or lower at the end of follow-up. Combining the criteria of an IOP greater than 21 and an IOP drop of at least 20%, the success rate was 71.8% (28/39) in TO eyes and 70.6% (24/34) in GO eyes. Conclusion. In this study the value of TO in controlling IOP was comparable to that of GO.
    Notes: Zusammenfassung Fragestellung. Die Wirksamkeit der Trabekulotomie (TO) als primäre operative Therapie bei kongenitalem Glaukom wurde mit der Wirksamkeit der Goniotomie (GO) verglichen. Patienten und Methoden. Retrospektiv wurden 39 Augen von 22 Kindern mit kongenitalem Glaukom untersucht, bei denen eine TO mit oder ohne kleine Trabekulektomie durchgeführt worden war. Die Ergebnisse wurden verglichen mit den Daten von 34 Augen von 21 Kindern mit kongenitalem Glaukom, bei denen eine GO durchgeführt worden war. Ergebnisse. Der mittlere präoperative intraokulare Druck (IOD) betrug 28,2±6,7 mmHG bei den TO-Augen und 31,0±7,9 mmHG bei den GO-Augen. Am Ende der Nachbeobachtungszeit (NBZ) betrug der mittlere IOD 17,7±6,0 mmHG bei den TO-Augen und 18,9±9,1 mmHG bei den GO-Augen. Bei 31/39 (79,5%) TO-Augen und bei 26/34 (76,5%) GO-Augen lag der IOD am Ende der NBZ≤21 mmHg. Verwendet man als Erfolgskriterium die Kombination aus IOD≤21 mmHg und IOD-Senkung≥20%, lag die Erfolgsquote bei 71,8% (28/39 TO-Augen) bzw. bei 70,6% (24/34 GO-Augen). Schlussfolgerung. Die Wirksamkeit der Trabekulotomie bezüglich der IOD-Senkung ist in dieser Studie vergleichbar mit der Wirksamkeit der Goniotomie.

    Description / Table of Contents: Summary 1. The male ofAnergates shows a reduction of some parts of the digestive system and the musculature of the skeleton. The volume of the brain is reduced by reduction of association centres. The anatomy of the female corresponds to a free-living species, only the stinging apparatus cannot be found. 2. During the reproductive phase a remarkable enlargement of all somatic cells takes place due to polyploidy with exception of the nervous system. To strengthen the exoskeleton the intersegmantal membranes are hardening. 3. As result of isolation ofAnergates certain analogies to regressive evolution of some cave animals are noted.
    Abstract: Résumé 1o Le mâle d'Anergates présente une réduction de la musculature squelettique et de quelques parties du tractus digestif. Le volume des ganglions cérébroïdes est diminué par suite de la réduction des centres d'association. L'anatomie de la femelle rappelle celle des femelles sauvages, à ceci près que l'aiguillon et ses annexes sont absents. 2o A part les cellules nerveuses, toutes les cellules somatiques de l'image subissent une croissance remarquable à cause de leur polyploïdie. Les membranes intersegmentales se durcissent et renforcent l'exosquelette. 3o Eu égard à l'isolement d'Anergates, on peut constater certaines analogies entre les phénomènes régressifs qu'il présente et ceux rencontrés chez des animaux cavernicoles.
    Notes: Zusammenfassung 1. Beim ♂ vonAnergates ist neben Teilen des Darmtraktes besonders die Skelettmuskulatur zurückgebildet. Das Gehirnvolumen wurde auf Kosten der assoziativen Zentren herabgesetzt. Der Bau des ♀ entspricht dem einer freilebenden Art, lediglich der Stachelapparat ist nicht mehr nachweisbar. 2. Postimaginal findet beim ♀ eine auffallende Vergrößerung aller Somazellen statt, für die — mit Ausnahme des Nervensystems — Polyploidisierungsvorgänge verantwortlich sind. Zur Festigung des Exoskeletts verhärten die Intersegmentalhäute. 3. Als Folge der Isolierung vonAnergates sind gewisse Analogien zur regressiven Evolution mancher Höhlentiere festzustellen.

    Notes: Summary.  Bovine herpesvirus type 1 (BHV-1) causes respiratory and genital diseases in cattle, whereas the closely related BHV-5 can induce severe meningoencephalitis in calves. To characterize BHV-5 glycoprotein C (gC5) within the backbone of BHV-1, three consecutive recombinant viruses were constructed: A deletion mutant (rBHV-1ΔgC blue) with gC1 replaced by the lacZ gene, an exchange mutant (rBHV-1gC5) with the lacZ of BHV-1ΔgC blue exchanged by gC5, and a rescue mutant (rescue BHV-1) from rBHV-1gC5 with an additional XbaI site in gC1. The recombinant and wildtype viruses were characterized on MDBK cells. Although no significant differences were observed in growth behaviour and entry kinetics, rBHV-1gC5 showed a distinct phenotype in a heparin blocking assay. The gC5 was able to transfer the heparin binding phenotype of BHV-5 to BHV-1. This indicates that gC1 and gC5 differ in their receptor binding qualities, which might modulate the ability of the viruses to spread within the central nervous system.

    Notes: Abstract Background: Traumatic diaphragmatic hernias are serious complications of blunt abdominal or thoracic trauma. In the early posttraumatic period, they are often missed, and they may be followed by a variety of subacute or chronic symptoms due to pulmonary or intestinal obstruction. Methods: We present three cases of traumatic diaphragmatic hernias. Two of them were successfully treated by laparoscopy and direct suturing during the early posttraumatic period; the other was treated 10 years after the trauma. Results: We found that laparoscopy is a safe, successful, and gentle procedure not only for diagnosis but for treatment as well. The postoperative course was uneventful in all cases. All patients remained asymptomatic during long-term follow-up (42–60 months). These results are promising. We expect the same good long-term results after laparoscopic repair as after open conventional surgery. Conclusion: We recommend that surgeons with sufficient experience in laparoscopy use a minimally invasive approach to treat chronic as well as acute traumatic diaphragmatic hernias in hemodynamically stable patients.
