Am 27. Februar 2021 war die 193 825 von Retrack vor dem Kesselwagenzug DGS 69615 von Köln Eifeltor nach Passau Gbf im Einsatz. Mit dieser Verbindung wird Anilin von Antwerpen nach Ungarn transportiert. Bei Edlhausen gelang ein Photo der Leistung.

Thyroïde de requin. L'image pointe sur un follicule thyroïdien, unité fonctionnelle de cette glande endocrine. Les follicules, à l'instar de ceux des poissons osseux, sont arrondis et présentent une cavité centrale remplie de colloïde (bleu métallique), forme de stockage des hormones thyroïdiennes. Ils sont séparés par des travées conjonctives (bleu foncé) en continuité avec la capsule de collagène qui délimite distinctement la glande chez les Chondrichtyens. Les cellules épithéliales, ou thyréocytes, entourant chaque follicule sont cubiques ou prismatiques, à cytoplasme clair (en rose) et noyau basal (en rouge). Elles sont dotées de microvillosités (à peine visibles ici) baignant dans la colloïde. Elles sont dotées de microvillosités (à peine visibles ici) baignant dans la colloïde. En comparant avec P12d_004, on remarque un épithélium plus haut et de petites vacuoles périphériques (incolores), signes d’une activité glandulaire plus importante. Les striations dans la colloïde = artéfact !

This magnification exhibits a thyroid follicle that represents
the functional unit of this endocrine gland. The follicles are spherical or ovoidal structures which cavities filled with colloid (ice blue). The thyroid follicles are surrounded and bound together by connective tissue (collagen in deep blue). All cartilaginous fishes have a thyroid contained within a connective tissue capsule. The follicular cells form a tight epithelium (in pink with red nuclei) and have microvilli (slightly discernible here) projecting into the follicular lumen. As compared to P12d_004 the height of the epithelium is taller and there are some reabsorption vacuoles (unstained) : these two observations indicate a more active thyroid gland. Striations in the colloid are artefacts.

Agfa factory in Rummelsburg near Berlin/Germany in 1877. In the background: the river Spree and the fishing village of Stralau on an peninsula.
The company was founded ten years earlier, in 1867, by Paul Mendelssohn Bartholdy, a son of the famous composer Felix Mendelssohn Bartholdy, and his distant relativ Carl Alexander (von) Martius. In 1872 it took over Dr. Jordan's Chemische Fabrik in Treptow, just a couple of kilometres further west. During the following decades, Agfa became one of the leading German chemical companies, dominating especially in the fields of chemical colours and photographic material.
Agfa factory at Wiesenufer, Treptow near Berlin/Germany, in 1877. In the foreground: Flutgraben, in the background: Görlitzer Eisenbahn.
This factory was founded in 1850 under the name of Dr. Jordan's Chemische Fabrik and taken over by Agfa in 1872, which was lead by Paul Mendelssohn Bartholdy and had its seat just a few kilometres further east, in Rummelsburg.
