Authors: Park Min‐Jung , Lee Sung‐Hee , Kim Eun‐Kyung , Lee Eun‐Jung , Park Sung‐Hwan , Kwok Seung‐Ki , Cho Mi‐La
Published: May 2016

Objective

This study was undertaken to assess the effect of myeloid‐derived suppressor cells (MDSCs) on various B cell subsets, including regulatory B cells, as well as to assess the potential therapeutic effects of MDSC infusion in an animal model of systemic lupus erythematosus (SLE).

Methods

Splenocytes were cultured with MDSCs, and the populations of various B cells and effector T cell subsets were analyzed by flow cytometry. Lupus mice (roquinsan/san mice) were treated intravenously with MDSCs obtained from C57BL/6 mice, and the levels of serum autoantibodies, degree of proteinuria, histologic changes in the kidney, and populations of various B cell and T cell subsets in the spleen were analyzed.

Results

Coculture of MDSCs with splenocytes from C57BL/6 mice resulted in an expansion of the population of interleukin‐10–producing B cells. The expansion of regulatory B cells was completely blocked by the addition of NG‐monomethyl‐l‐arginine, an inhibitor of inducible nitric oxide synthase (iNOS). Infusion of MDSCs resulted in a reduction of serum anti–double‐stranded DNA antibody levels and degree of proteinuria and an improvement in renal pathology in the roquinsan/san mice. MDSC coculture also resulted in a decrease in the population of effector B cells, such as germinal center B cells and plasma cells. Moreover, infusion of MDSCs resulted in an expansion of the regulatory B cell population as well as a decrease in follicular helper T cells, Th1 cells, and Th17 cells in the spleens of roquinsan/san mice.

Conclusion

Our results indicate the MDSCs induce expansion of regulatory B cells via iNOS and ameliorate autoimmunity in a murine model of SLE. These findings indicate that MDSCs may be a promising therapeutic strategy for targeting B cell–mediated autoimmune diseases.

Ein pharmakologischer Prozeß und seine stochastische Beschreibung
Authors: Herrmann H.
Published: May 2016

Die vorliegende Erörterung, sie greift zurück auf die Dissertation des Verfassers, widmet sich der quantitativen Beschreibung des sog. Reiz‐Antwort‐Prozesees der Pharmakon‐Rezeptor‐Theorie mit Hilfe von stochastischen Modellen. Zunächst wird der pharmakologische Prozeß erfaßt durch Hypothesen über Eigenschaften und Verhalten von Pharmakon‐Molekülen und Rezeptoren und über die Art und Entstehung von Antworten. In das zu konstruierende stochastische Modell für den pharmakologiechen Vorgang geht ein zweidimensionaler homogener Geburts‐ und Todesprozeß mit nichtlinearen Übergangsintensitäten ein. Die Existenz und Eindeutigkeit von Lösungen des zugehörigen Kolmogorov'schen Vorwärtsdifferentialgleichungssystems wird nachgewiesen. Ferner wird gezeigt, daß der stochastische Prozeß ergodisch ist und so die Beschreibung des pharmakologischen Gleichgewichtszustandes erlaubt. Bei nur geringfügig geändertem Modellansatz ist es trotz nichtlinearer Übergangsintensitäten möglich, die besonders interessierenden Erwartungswert‐ und Kovarianzfunktionen als Lösungen gewisser Differentialgleichungen explizit anzugeben. Dazu ein analytischer Vergleich mit den entsprechenden Funktionen eines analogen deterministischen Modells einschließlich graphischer Darstellung.
MiRNA expression profile of ionizing radiation‐induced liver injury in mouse using deep sequencing
Authors: Lu Jike , Chen Chen , Hao Limin , Zheng Zhiqiang , Zhang Naixun , Wang Zhenyu
Published: May 2016

In order to investigate the potential regulatory roles of microRNAs (miRNAs) in mouse response to ionizing radiation (IR), the small RNA libraries from liver tissues of mice with or without ionizing radiation (IR) were sequenced by high‐throughput deep sequencing technology. A total of 270 miRNAs including 212 known and 58 potentially novel miRNAs were identified. Within these miRNAs, there were 48 miRNAs that were differentially expressed, including 27 known and 21 novel miRNAs. The results of quantitative RT‐polymerase chain reaction (qRT‐PCR) were in consistent with the sequencing analysis. Target gene prediction, function annotation, and pathway of the identified miRNAs were analyzed using RNAhybrid, miRanda software and Swiss‐Prot, Gene Ontology (GO), Clusters of Orthologous Groups (COG), Kyoto Encyclopedia of Genes, and Genomes (KEGG) and non‐redundant (NR) databases. These results should be useful to investigate the biological function of miRNAs under IR‐induced liver injury.
Optimal Design of a Gas‐to‐Liquids Process with a Staged Fischer‐Tropsch Reactor
Authors: Rafiee Ahmad , Panahi Mehdi
Published: May 2016

The optimal design of a natural gas‐to‐liquid hydrocarbons (GTL) process with a multistage cobalt‐based Fischer‐Tropsch reactor and interstage product separation is considered. The objective function is to maximize the wax (C21+) production rate at the end of the reactor path. Sectioning of the Fischer‐Tropsch reactor increases the chain growth probability inside the reactor which results in a higher production of wax. The carbon efficiency of the two‐stage reactor is distinctly higher than that of the single‐stage reactor.

ω‐Phenyl‐ω‐(trimethylsilyl)alkyllithium compounds such as (I) show form out of five theoretically conceivable possibilities for intramolecular stabilization depending on the solvent and on the chain length n.

The main reaction, however for n = 3 and 4 only, is represented by the 1,n trimethyl silyl shift via a cyclic ate complex as an intermediate which partly splits off MeLi yielding the corresponding silacycloalkane derivatives.
