Adulteration of meat products with murine meat poses a huge threat to consumer health and leads to serious disruption in food markets. Species authentication of murine meat is still technically challenging. We, therefore, developed a species-specific PCR kit consisting of murine meat DNA extraction, PCR reaction and identifying systems. GSK2830371 datasheet We designed novel universal primers targeting highly conserved region on mitochondrial cytochrome b gene (cyt b) from four murines (lab rats, lab mice, wild rat and wild mice), as well as specific primers for meat from four widely consumed animal species, cattle, sheep, duck and donkey. Simultaneously, pasmid inserted specific cyt b fragment was cloned and used as the internal positve control in the kit. The kit parameters of specificity, sensitivity, stability and validity were determined using mimic counterfeiting meatball. The specificity of the DNA detection kit was 100% in authentication of the four fraudulent meats of cattle, sheep, duck and donkey mixed murine meat. The minimum detection limit of the sample DNA was 0.1 μg. The kit, which had freeze-thawed up to 20 times and stored for 1 year, also was powerful in detecting an amount of 0.1 mg in artificial counterfeited cattle, sheep, duck and donkey meat products. The murine-species DNA detection kit proposed in this study has proved to be a simple, accurate and effective assay, and can be applied to the identification of murine meat traces in common edible meat, to ensure the realisable implementation of meat product market supervision.in English, German Zusammenfassung. Fragestellung Das Beratungsangebot [U25] Deutschland bietet Hilfe für Jugendliche und junge Erwachsene in Krisensituationen oder bei Suizidgefahr. Die Ratsuchenden bleiben anonym, die Beratung wird durch ehrenamtlich tätige Gleichaltrige (Peers) durchgeführt. Durch den Online-Zugang ist das Angebot besonders niederschwellig. Die vorliegende Untersuchung befasst sich mit der Frage, ob junge Menschen in Krisensituationen und bei Suizidgefahr durch die Online-Peerberatung [U25] erreicht werden und welche Merkmale die erreichte Klientel auszeichnen. Methodik Datengrundlage bietet die Auswertung der Dokumentation von 1062 Beratungsprozessen aus dem Jahr 2017 sowie eine Interviewstudie mit Peerberaterinnen und -beratern des [U25]-Standortes Nürnberg (n = 13). Ergebnisse Die Daten deuten darauf hin, dass das Ziel, junge Menschen in (suizidalen) Krisen zu erreichen, durch [U25] gut erfüllt wird. Dies spiegelt sich auch in der hohen Inanspruchnahme des Angebots wider. Allerdings nehmen junge Männer das Angebot weniger häufig wahr. Es liegen auch erste Hinweise darauf vor, dass junge Menschen aus bildungsfernen Familien weniger gut erreicht werden. Schlussfolgerungen [U25] bietet einen vielversprechenden Ansatz, um junge Menschen in Krisensituationen niederschwellig zu erreichen und bei Bedarf zur Inanspruchnahme von Präsenzangeboten hinzuführen. Konzepte zur gezielten Ansprache von jungen Männern und Personen aus bildungsfernen Schichten müssen erarbeitet und evaluiert werden.The modular structure of bacterial ribonuclease P (RNase P) ribozymes, which recognize tertiary structures of precursor tRNAs (pre-tRNAs) to cleave their 5' leader sequence, can be dissected physically into the two structured domain RNAs (S-domain and C-domain). Separately prepared S-domain RNA and C-domain RNA assemble to form bimolecular forms of RNase P ribozymes. We analyzed the effects of polyethylene glycols (PEGs) on pre-tRNA cleavage catalyzed by bimolecular RNase P ribozymes to examine the effects of molecular crowding on the reaction. PEG molecular crowders significantly enhanced the activities of bimolecular RNase P ribozymes, some of which were hardly active without PEGs.Purpose Stereotactic body radiation therapy (SBRT) is emerging as a new noninvasive treatment in patients with primary liver carcinoma or liver-confined metastatic cancer. However, the radiobiological targets remain a subject of debate. Here, we investigated the potential biological effects of the radiation on the human hepatocellular carcinoma HepG2 cells.Materials and methods Firstly, HepG2 cells were divided into three groups control group, 3.5 Gy*8f group (L group), and 15 Gy*1f group (H group). After treatment, cell proliferation was examined using 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide and plate colony formation assays. Cell cycle and apoptosis were assessed using propidium iodide and Hoechst 33258 staining, respectively. Furthermore, the mechanisms underlying irradiation-induced cell cycle arrest and cell apoptosis were investigated by Western blot assay.Results Irradiation could effectively inhibit the proliferation and colony formation of HepG2 cells, and the single high dose irradiation showed stronger inhibitory effects. Irradiation-induced cell cycle arrest at G2/M phase in HepG2 cell, during which the expression levels of cyclin B1, CDK1, and p-CDK1 proteins were downregulated, whereas expression of p21 was upregulated in the irradiated HepG2 cells. After irradiation, typical morphological changes of apoptosis in HepG2 cells were observed; the number of cell apoptosis and the expression of apoptosis associated proteins were significantly increased in HepG2 cells by high dose irradiation compared with low dose irradiation. Additionally, compared with low dose irradiation, high dose irradiation significantly downregulated the phosphorylated proteins in the Ras/Raf/MEK/ERK signaling pathway.Conclusions Our results suggest that irradiation applied in SBRT, particularly single high dose irradiation, mediates its anti-tumor effects by inducing cell cycle arrest and apoptosis via modulation of the Ras/Raf/MEK/ERK signaling pathway.Introduction Theory of mind (ToM) has been established as one of the most investigated and pronounced social cognitive deficits in schizophrenia. Yet, knowledge on whether measures of ToM can be used and compared across cultures is sparse. In this study, we used two simple, non-verbal ToM tests in patients with schizophrenia and non-clinical controls from China and Denmark to investigate whether culture has an impact on ToM performance.Methods Sixty-six patients with schizophrenia (35 Chinese) and 67 matched non-clinical controls (38 Chinese) from China and Denmark were tested with Brünés Picture Sequencing Task and Animated Triangles Task. We compared three models for each outcome variable in order to investigate which model best fitted the data the first model included group (controls, patients) as a predictor variable, the second included group and nationality (Chinese, Danish), and the third included both predictors and their interaction.Results On most ToM subtests, culture seemed to play a role. Only performance on Brüne's 1st order ToM were best described as similar in both countries.
