Pausing for thought: Disrupting the early transcription elongation checkpoint leads to developmental defects and tumourigenesis
Authors: Jennings Barbara H. 
Published: April 2013

AbstractFactors affecting transcriptional elongation have been characterized extensively in in vitro, single cell (yeast) and cell culture systems; however, data from the context of multicellular organisms has been relatively scarce. While studies in homogeneous cell populations have been highly informative about the underlying molecular mechanisms and prevalence of polymerase pausing, they do not reveal the biological impact of perturbing this regulation in an animal. The core components regulating pausing are expressed in all animal cells and are recruited to the majority of genes, however, disrupting their function often results in discrete phenotypic effects. Mutations in genes encoding key regulators of transcriptional pausing have been recovered from several genetic screens for specific phenotypes or interactions with specific factors in mice, zebrafish and flies. Analysis of these mutations has revealed that control of transcriptional pausing is critical for a diverse range of biological pathways essential for animal development and survival.
Preparation of water‐soluble CdSe quantum dots and its application for nitrite detection in the anodic electrochemiluminescence
Authors: Yao Xun , Yan Panpan , Zhang Kai , Li Jianguo 
Published: April 2013

ABSTRACTWater‐soluble CdSe quantum dots (QDs) have been prepared by using L‐cysteine as the stabilizer in an aqueous phase under the optimized conditions. The characteristics and shapes of CdSe QDs have been proposed on the basis of UV‐Vis and fluorescence spectra. A rapid analytical method for electrochemiluminescence (ECL) determination of nitrite has been developed on the basis of the quenching effect on anodic ECL emission of CdSe QDs under the optimum experimental conditions. In a neutral system and at a relatively low potential (+0.960 V), the ECL emission of CdSe QDs could be greatly enhanced by sulfite and could be gradually quenched by nitrite at an indium tin oxide (ITO) electrode. The proposed method may allow the measurement of nitrite ranging from 1 μM to 0.5 mM with a correlation coefficient of 0.9956 (n = 10) and a detection limit of 0.2 μM (3σ), and the relative standard deviation for 10 μM nitrite (n = 9) is 1.72 %. The proposed method could be adopted for the sensitive detection of ECL quenchers by using nitrite as a model molecule. Copyright © 2013 John Wiley & Sons, Ltd.
Transgastric appendicectomy
Authors: Kaehler G , Schoenberg M B , Kienle P , Post S , Magdeburg R 
Published: April 2013

Abstract

Background
Experimental studies and small anecdotal reports have documented the potential and feasibility of transgastric appendicectomy. This paper reports the results of the new technique in a selected group of patients.

Methods
From April 2010 transgastric appendicectomy was offered to all patients with acute appendicitis, but without generalized peritonitis or local contraindications.

Results
Of 111 eligible patients 15 agreed to undergo the transgastric operation. After conversion of the first case to laparoscopy because of severe inflammation and adhesions, the following 14 consecutive transgastric procedures were completed. Two patients with initial peritonitis required laparoscopic lavage 4 days after transgastric appendicectomy, but no leaks were detected at the appendiceal stump or stomach.

Conclusion
These preliminary results have shown the feasibility of this innovative procedure. Additional studies, however, are required to demonstrate the specific advantages and disadvantages of this approach, and define its role in clinical surgery.
Simultaneous quantification of paeoniflorin, nobiletin, tangeretin, liquiritigenin, isoliquiritigenin, liquiritin and formononetin from Si‐Ni‐San extract in rat plasma and tissues by liquid chromatography–tandem mass spectrometry
Authors: Li Tianxue , Yan Zhixiang , Zhou Chen , Sun Jian , Jiang Chuan , Yang Xinghao 
Published: April 2013

ABSTRACTIn this study, a sensitive and reliable liquid chromatography–tandem mass spectrometry (LC‐MS/MS) method was developed and validated for the determination of seven bioactive components including paeoniflorin, nobiletin, tangeretin, liquiritigenin, isoliquiritigenin, liquiritin and formononetin in rat plasma and tissues after oral administration of Si‐Ni‐San extract using astragaloside IV as internal standard (IS). The plasma and tissue samples were extracted by solid‐phase extraction. Chromatographic separation was accomplished on a C18 column with a multiple‐step gradient elution. The quantification was obtained by scanning with multiple reaction monitoring via an electrospray ionization source that was operated by switching between the positive and negative modes in two MS/MS scan segments. Full validation of the assay was implemented. In conclusion, this method demonstrated good linearity and specificity. The lower limits of quantification for the analytes were <7.5 ng/mL. Intra‐ and inter‐day precisions (RSD) were <12.5% and accuracy (RE) ranged from −10.2 to 7.3%. The average recoveries of the analytes from rat plasma and tissues were >65.2% and 58.6%, respectively. The validated method was further applied to the determination of actual rat plasma and tissues after oral administration of Si‐Ni‐San extract. The results provided a meaningful basis for the clinical application of this prescription. Copyright © 2013 John Wiley & Sons, Ltd.
Chemotaxonomic Importance of the Essential‐Oil Composition in Two Subspecies of Teucrium stocksianumBoiss. from Iran

Published: April 2013

AbstractThe hydrodistilled essential oils obtained from aerial flowering parts of Teucrium stocksianum ssp. stocksianum (TSS) and T. stocksianum ssp. gabrielae (TSG) from Iran were analyzed by capillary GC and GC/MS. The oil analysis of two subspecies led to the identification of 65 compounds that accounted for 93.3 and 95.1% of the total oil compositions, respectively. Sesquiterpenoids (52.9%) constituted the main compounds in the essential oil of TSS represented mainly by cis‐sesquisabinene hydrate (12.0%), followed by epi‐β‐bisabolol (6.6%), guaiol (5.4%), and β‐eudesmol (4.4%), whilst monoterpenoids (61.2%) were found to be the major components of the oil of TSG, represented by α‐pinene (23.0%), β‐pinene (13.0%), myrcene (6.3%), and sabinene (6.3%). The principal component in both subspecies, TSS and TSG, was α‐pinene (22.0 and 23.0%, resp.) and β‐pinene (6.5 and 13.0%, resp.). epi‐α‐Cadinol, myrcene, and sabinene, which were detected as principal compounds of TSG, were characterized in lower amounts (<1.5%) in the oil of TSS. Seven components were identified in the oil of TSS corresponding to 25.9% of total oil, which were totally absent in the oil of TSG, of which cis‐sesquisabinene hydrate (12.0%), guaiol (5.4%), and β‐eudesmol (4.4%) were in considerable amounts. Taxonomic position of the subspecies is discussed on the basis of phytochemical data.
Kolbe‐Schmitt Flow Synthesis in Aqueous Solution – From Lab Capillary Reactor to Pilot Plant
Authors: Krtschil U. , Hessel V. , Kost H.‐J. , Reinhard D. 
Published: April 2013

AbstractSignificant process intensification was achieved for the continuously operated Kolbe‐Schmitt synthesis of 2,4‐dihydroxybenzoic acid (β‐resorcylic acid) on laboratory scale by using different approaches opening novel process windows. The results of the optimal process variant, both from the economic and ecological view, were scaled up to the pilot scale. In a first step, the synthesis from resorcinol in aqueous potassium hydrogen carbonate solution was transferred from the capillary reactor to a tailor‐made electrically heated microstructured reactor comprising 40 microchannels and enabling a 25‐fold increase of the capacity. In a second step, a pilot plant comprising three of such reactors operated in parallel was built and successfully tested with the same reaction.
