  abstract  = {The gene encoding the human homologue of the guinea pig uterine bombesm receptor [( 1992) Eur. J. Biochem. 208,405] was isolated from a genomic lambda library by the PCR/homology screening approach. The gene spans more than 4 kb and consists of 3 exons and 2 introns. The deduced amino acid sequence shows about 86\% identity to that of guinea pig bombesin receptor. This subtype of bombesin receptor is expressed in the pregnant uterus and in two human tumour cell lines, T47D (ductal breast carcinoma) and A431 (epidermal carcinoma). PCR analysis of genomic DNA from human-mouse cell hybrids allows the cloned gene to be localized to the region q26q28 on chromosome X.},

  abstract  = {The parotid gland is one of the major salivary glands producing a serous secretion, and it plays an essential role in the digestive and immune systems. Knowledge of peroxisomes in the human parotid gland is minimal; furthermore, the peroxisomal compartment and its enzyme composition in the different cell types of the human parotid gland have never been subjected to a detailed investigation. Therefore, we performed a comprehensive analysis of peroxisomes in the human parotid gland's striated duct and acinar cells. We combined biochemical techniques with various light and electron microscopy techniques to determine the localization of parotid secretory proteins and different peroxisomal marker proteins in parotid gland tissue. Moreover, we analyzed the mRNA of numerous gene encoding proteins localized in peroxisomes using real-time quantitative PCR. The results confirm the presence of peroxisomes in all striated duct and acinar cells of the human parotid gland. Immunofluorescence analyses for various peroxisomal proteins showed a higher abundance and more intense staining in striated duct cells compared to acinar cells. Moreover, human parotid glands comprise high quantities of catalase and other antioxidative enzymes in discrete subcellular regions, suggesting their role in protection against oxidative stress. This study provides the first thorough description of parotid peroxisomes in different parotid cell types of healthy human tissue.},

We identified a heterogeneous subset of low-density neutrophils (LDNs) that appear transiently in self-resolving inflammation but accumulate continuously with cancer progression. LDNs display impaired neutrophil function and immunosuppressive properties, characteristics that are in stark contrast to those of mature, high-density neutrophils (HDNs). LDNs consist of both immature myeloid-derived suppressor cells (MDSCs) and mature cells that are derived from HDNs in a TGF-beta-dependent mechanism. Our findings identify three distinct populations of circulating neutrophils and challenge the concept that mature neutrophils have limited plasticity. Furthermore, our findings provide a mechanistic explanation to mitigate the controversy surrounding neutrophil function in cancer.},

  abstract  = {We demonstrated previously that phosphocholine and phosphocholine-modified macromolecules efficiently inhibit ATP-dependent release of interleukin-1β from human and murine monocytes by a mechanism involving nicotinic acetylcholine receptors (nAChR). Interleukin-1β is a potent pro-inflammatory cytokine of innate immunity that plays pivotal roles in host defence. Control of interleukin-1β release is vital as excessively high systemic levels cause life threatening inflammatory diseases. In spite of its structural similarity to acetylcholine, there are no other reports on interactions of phosphocholine with nAChR. In this study, we demonstrate that phosphocholine inhibits ion-channel function of ATP receptor P2X7 in monocytic cells via nAChR containing α9 and α10 subunits. In stark contrast to choline, phosphocholine does not evoke ion current responses in Xenopus laevis oocytes, which heterologously express functional homomeric nAChR composed of α9 subunits or heteromeric receptors containing α9 and α10 subunits. Preincubation of these oocytes with phosphocholine, however, attenuated choline-induced ion current changes, suggesting that phosphocholine may act as a silent agonist. We conclude that phophocholine activates immuno-modulatory nAChR expressed by monocytes but does not stimulate canonical ionotropic receptor functions.},

  abstract  = {On the basis of four relev{\´e}es of hedges around Straiton en Dailly in South Ayrshire, Scotland, some features of hedges are discussed. On the basis of the brambles, the vegetation of these hedges can be assigned to the Pruno-Rubion sprengelii, which comprises the bramble scrubs of circumneutral and nutrient rich soils in West Europe (Haveman et al. 2017, Haveman \& de Ronde 2019). Until now, this alliance was thought to be restricted to the northwestern edge of the European continent, but based on these relev{\´e}es and the known distribution area of Rubus nemoralis and Rubus polyanthemus, both characteristic for the Pruno-Rubion sprengelii, large parts of North England and Scotland have to be included in the distribution area of the alliance. The Pruno-Rubion sprengelii is optimally developed in rather narrow structures, like hedges, which are pruned every year. Here, brambles and herbs alike can grow with and under the shrubs, facilitated by the light that reaches large parts of the ground. Where the economic base of hedges perishes, they are not longer maintained, and the shrubs can grow out to their natural proportions. This changes the amount of light reaching the surface in the inner parts of the thicket, changing the competition between the species. The brambles as well as the herbs are displaced to the outer edges of the scrub, and the vegetation "dissociates" in a high-growing scrub, a fore-mantle ("cuff") with brambles, and a fringe with perennial herbs. These elements can hardly ever be assigned to the Pruno-Rubion anymore. The Pruno-Rubion sprengelii in optima forma is a scrub in which the three elements (shrubs, brambles, and herbs) grow closely intertwined. This is rarely found in natural landscapes, and thus the alliance is a typical element of the old farmer landscape. What is more: the typical species of the alliance, like Rubus nemoralis and R. polyanthemus, could only evolve after the landscape was opened by farmers in the last six millennia (Matzke-Hajek 1997), giving way to Rubus ulmifolius to expand its distribution area. This caused an explosion of hybrids which stabilised through apomixis into the wealth of Rubus species inhibiting the West European landscape nowadays (Sochor et al. 2015). Many of these species have their original home in a man-made landscape. Therefore, the Pruno-Rubion sprengelii can be characterised as a "farmers alliance" pur sang.},

  abstract  = {Das Synaptonemalkomplexprotein SYCP1 ist eine Strukturkomponente des Synaptonemalkomplexes (SC) von Saeugern, einer meiosespezifischen Struktur, die wesentlich fuer die Synapse, Rekombination und Segregation homologer Chromosomen ist. Der SC besteht aus zwei lateralen Elementen (LEs) und einer zentralen Region (CR), in deren Mitte das zentrale Element (CE) liegt. Dabei sind die LEs den Achsen der homologen Chromosomen aufgelagert und werden in der CR durch Transversalfilamente (TFs) mit dem CE verbunden. Im Protein SYCP1 (125 kDa) flankieren zwei nicht-helikale terminale Domaenen eine ausgedehnte zentrale „Coiled-Coil"-Domaene. Fuer diese Domaene wird angenommen, dass sie die die Kluft zwischen LEs und CE ueberbrueckt, wobei die C-Termini in den LEs verankert sind und die N-Termini im CE lokalisiert wurden. Um die molekulare Architektur des SC besser zu verstehen und die Bedeutung von SYCP1 f\&\#252;r die Zusammenlagerung des SC aufzudecken, wurden die Polymerisationseigenschaften von SYCP1 erforscht. Dazu wurde das Protein in somatischen Zellen exprimiert. In diesem experimentellem Ansatz polymerisierte SYCP1 autonom zu filamentoesen Strukturen, welche sich auf ultrastruktureller Ebene als alternierende elektronendichte Balken offenbarten, die ueber TFs verbunden waren. Dieser Aufbau glich parallel aneinander gereihten Stapeln von SCs, so genannten Polykomplexen (PCs). Die Analyse der Orientierung der SYCP1 Molekuele innerhalb der PCs erwies, dass diese hochorganisiert vorliegen und die Organisation von SYCP1 innerhalb von PCs und SCs identisch ist. Folglich kann sich SYCP1 sogar in Abwesenheit anderer SC-Proteine zu Strukturen zusammenlagern, die der CR entsprechen und muss dementsprechend beim Aufbau der CR des SC den grundlegenden Faktor darstellen. F\&\#252;r eine genauere Analyse wurden ausgewaehlte Mutanten von SYCP1 exprimiert. Molek\&\#252;le mit modifizierter Laenge der zentralen alpha-helikalen Domaene resultierten in der Bildung von PCs mit ver\&\#228;nderter Weite der CR. Dies beweist, dass die „Coiled-Coil"-Domaene den Abstand der CR eines PC bestimmt und impliziert dieselbe Funktion in der SC-Bildung. Darueber hinaus wurde gezeigt, dass SYCP1 Molekuele mit Deletion des nicht-helikalen N-Terminus immer noch in der Lage sind, PCs zu bilden, diese Eigenschaft aber stark eingeschraenkt ist. Das bezeugt die Bedeutung des N-Terminus sowohl in der PC-Bildung als auch im Aufbau des CE von SCs, weist aber dabei auch dem vorderen Teil der „Coiled-Coil"-Domaene eine wichtige Rolle zu. Im Gegensatz dazu war bei Mutanten mit Deletion des nicht-helikalen C-Terminus die PC-Bildung vollstaendig blockiert, was auf eine gro\&\#223;e Bedeutung dieser Domaene fuer die Polymerisation hinweist. Ein weiterer Hauptgegenstand der Arbeit war die Charakterisierung von Bindungspartnern von SYCP1. \&\#220;ber Immungoldlokalisation auf Maushoden konnten die Proteine Syce1 und Cesc1 als erste ausschliessliche Komponenten des CE des SC bestimmt werden. Zusaetzlich wurde die Interaktion dieser Proteine mit dem N-Terminus von SYCP1 verifiziert. SYCP1 bildet also die Grundstruktur des CE aus und rekrutiert Syce1 und Cesc1.},

  abstract  = {Objectives: This study investigated the feasibility and image quality of ultra-low-dose unenhanced abdominal CT using photon-counting detector technology and tin prefiltration. Materials and Methods: Employing a first-generation photon-counting CT scanner, eight cadaveric specimens were examined both with tin prefiltration (Sn 100 kVp) and polychromatic (120 kVp) scan protocols matched for radiation dose at three different levels: standard-dose (3 mGy), low-dose (1 mGy) and ultra-low-dose (0.5 mGy). Image quality was evaluated quantitatively by means of contrast-to-noise-ratios (CNR) with regions of interest placed in the renal cortex and subcutaneous fat. Additionally, three independent radiologists performed subjective evaluation of image quality. The intraclass correlation coefficient was calculated as a measure of interrater reliability. Results: Irrespective of scan mode, CNR in the renal cortex decreased with lower radiation dose. Despite similar mean energy of the applied x-ray spectrum, CNR was superior for Sn 100 kVp over 120 kVp at standard-dose (17.75 ± 3.51 vs. 14.13 ± 4.02), low-dose (13.99 ± 2.6 vs. 10.68 ± 2.17) and ultra-low-dose levels (8.88 ± 2.01 vs. 11.06 ± 1.74) (all p ≤ 0.05). Subjective image quality was highest for both standard-dose protocols (score 5; interquartile range 5-5). While no difference was ascertained between Sn 100 kVp and 120 kVp examinations at standard and low-dose levels, the subjective image quality of tin-filtered scans was superior to 120 kVp with ultra-low radiation dose (p < 0.05). An intraclass correlation coefficient of 0.844 (95\% confidence interval 0.763-0.906; p < 0.001) indicated good interrater reliability. Conclusions: Photon-counting detector CT permits excellent image quality in unenhanced abdominal CT with very low radiation dose. Employment of tin prefiltration at 100 kVp instead of polychromatic imaging at 120 kVp increases the image quality even further in the ultra-low-dose range of 0.5 mGy.},
