    Notes: Abstract Live reptant decapod crustaceans have never been collected on the Antarctic continental shelf, although shrimps occur locally in large quantities. Therefore, the collection of four male individuals of the anomuran decapod Lithodes murrayi off Peter I Island, close to the Antarctic Continent, between 180 and 260 m water depth in February 1994 is of particular relevance for further studies on the origin and adaptation of Antarctic decapods. Another five specimens were observed in situ by a remotely operated vehicle at the same location.

    Description / Table of Contents: Summary The vascular organization of human spermatic cord was analyzed by means of injection and by casting preparation of the testicular artery and veins of the pampiniform plexus after orchiectomy. After leaving the human testis, the testicular veins are organized in two main groups and form two vein plexus. One of these vein groups forms a tight plexus around the testicular artery. Computer-aided 3-D reconstructions based on the paraffin serial sections of the human spermatic cord allowed us to demonstrate the relation between the blood vessels and the other tissue structures of the spermatic cord. The results obtained allowed us to subdivide the human spermatic cord into three compartments. The dorsomedial compartment contains the vas deferens and its blood vessels. The middle compartment contains the testicular artery and the vein group which forms a tight plexus around this artery. The ventrolateral compartment contains a vein group which shows no topographic relation to the testicular artery. This vein group is embedded in a large, macroscopically visible volume of fatty tissue. To be sure of sparing the testicular artery during antegrade sclerotherapy this vein group should be prepared.
    Notes: Zusammenfassung Anhand von Gefäßausgußpräparaten (A. testicularis und Venen des Plexus pampiniformis) und der computergestützten 3D-Rekonstruktionen von Orchiektomiepräparaten wurde die vaskuläre Organisation des menschlichen Samenstrangs untersucht. Die testikulären Venen bilden beim Verlassen des Hodens 2 Venengruppen, welche jeweils ein Venennetz darstellen. Eines dieser Venennetze umgibt die A. testicularis. Venovenöse Anastomosen kommen zwischen beiden Venengruppen deutlich seltener vor, als innerhalb der jeweiligen Gruppe. Venenklappen wurden in beiden Venengruppen des Plexus pampiniformis im untersuchten Material selten und in großen Abständen beobachtet. Statt dessen sind in den Ausgußpräparaten in kurzen und regelmäßigen Abständen zirkuläre bis halbzirkuläre Verengungen der Gefäßlichtungen zu finden. Eine computergestützte 3D-Rekonstruktion von Paraffinserienschnitten veranschaulicht die Beziehung der Gefäße zu den anderen Gewebestrukturen des Samenstrangs. Aufgrund dieser Ergebnisse kann der Samenstrang in 3 Kompartments unterteilt werden: Im dorsomedialen Drittel befindet sich der Ductus deferens mit den den Ductus umgebenden Gefäßen. Im mittleren Drittel verläuft die Venengruppe, die um die A. testicularis ein dichtes Venennetz bildet. Im äußeren ventrolateralen Drittel ist die Venengruppe zu finden, die keine topographische Beziehung zur A. testicularis aufweist. Diese Venengruppe ist in ein gut entwickeltes, makroskopisch sichtbares Fettgewebe eingebettet. Bei der antegraden Sklerosierung der Varikozele testis sollten diese Venen aufgesucht werden, um die A. testicularis sicher zu schonen.

    Notes: [Auszug] Ectomycorrhizae are mutualistic associations between a vascular plant root and a fungus; they are the dominant nutrient-gathering organs in most temperate forest ecosystems3. These mutualisms vary from general to specific, but when specificity occurs it is one-sided: fungal species may be specific ...

    Notes: Abstract. Human spermatic cords were investigated by means of cast preparations, light-microscopic examination and computer-aided 3-dimensional reconstructions from serial sections of paraffin-embedded material. After leaving the testis, the testicular veins formed two principal groups co-existing side by side. Numerous veno-venous anastomoses could be observed within each individual group, whereas only a few mutual intergroup anastomoses were found. The testicular artery ran within one group but showed no close topographical relationship to the other group. Light microscopy of the serial sections revealed that the group of veins with no close topographical relationship to the testicular artery ran at a distance of several centimeters embedded within fatty tissue. With the help of computer-aided 3-dimensional reconstructions, a spatial picture of the vascular organization was obtained. These results allowed the following classification of the veins of the pampiniform plexus. Group-I veins formed a tight plexus around the testicular artery by means of veno-venous anastomoses. Group-II veins formed veno-venous anastomoses between each other and ran over at a sizeable distance embedded in fatty tissue but showed no close topographical relationship to the testicular artery. Group-III vessels formed veno-venous anastomoses between group-I and group-II. Group IV veins formed arterio-venous anastomoses with the testicular artery. Based on the differences in wall structure and diameter, a subclassification in group-I and group-II was undertaken. This organization of the veins of the human pampiniform plexus should further the understanding of physiological processes, such as the transfer of hormones and other substances from the veins to the testicular artery and vice versa. It should also facilitate the tracing of the veins during antegrade sclerosing.

    Description: Studies of convergent margin tectonics along the Japan Trench Transect are based on geophysical as well as on drill and conventional sampling data. The large number of geophysical and geological studies in the 1960's made this area an attractive target for convergent margin drill core sampling. Once the transect was scheduled for drilling by the Glomar Challenger, the earth science community in Japan intensified its efforts to collect geophysical and geological data within the transect area. Many of these data are published in Japanese and international journals. This chapter describes both the seismic reflection records along which Legs 56 and 57 drilling took place and the reflection records made after drilling. The seismic data are interpreted in light of the drilling results.

    Description: Human monocytic myeloid-derived suppressor cells (MO-MDSCs) within the hepatic compartment suppress inflammation and impair immune surveillance in liver cancer. It is currently not known whether recruitment of MO-MDSCs from blood via hepatic sinusoidal endothelium (HSEC) contributes to their enrichment within the hepatic compartment. We compared the transmigratory potential of MO-MDSCs and monocytes after adhesion to hepatic endothelial monolayers in flow-based assays that mimic in vivo shear stress in the sinusoids. Despite comparable binding to HSEC monolayers, proportionally fewer MO-MDSCs underwent transendothelial migration, indicating that the final steps of extravasation, where actin polymerization plays an important role, are impaired in MO-MDSCs. In this article, we found reduced levels of CD13 on MO-MDSCs, which has recently been reported to control cell motility in monocytes, alongside reduced VLA-4 expression, an integrin predominantly involved in adherence to the apical side of the endothelium. CD13 and VLA-4 blocking and activating Abs were used in flow-based adhesion assays, live-cell imaging of motility, and actin polymerization studies to confirm a role for CD13 in impaired MO-MDSC transmigration. These findings indicate that CD13 significantly contributes to tissue infiltration by MO-MDSCs and monocytes, thereby contributing to the pathogenesis of hepatic inflammation.
