Content analysis of textbooks (political knowledge, applied economics, organization and management) of Austria's high school course on the main and basic principles of social responsibility

In the last decade, social responsibility emerged as a field of study that was previously called "Urban Education and Citizenship". This new concept is much broader, in the sense that it means the development of social skills that enable a person to be a responsible and active member of the larger society and political community. In this regard, education has a key and essential role, and in fact, the main challenge in the education system is to match the society's culture with the patterns and goals. Social responsibility, as one of the main goals of educational planners in coding the textbooks, must be considered. To understand and investigate this issue, high school textbooks in Austria, due to having the most advanced and accepted educational systems in the world, were evaluated. This article aims to determine the components of social responsibility in the content of Austrian high school textbooks (teaching political knowledge, applied economics, organization and management), based on qualitative content analysis. It seeks to answer the question that to what extent the social responsibility has been considered in these textbooks? Results show that the economic dimension of social responsibility has been considered more than the social dimension in the mentioned books

In vitro activities of tetracyclines against different clones of multidrug-resistant Acinetobacter baumannii isolates from two Iranian hospitals.

Acinetobacter baumannii has emerged as one of the most challenging healthcare-related pathogens and its occurrence has increased worldwide, especially in patients admitted to intensive care units. A. baumannii isolates are frequently resistant to multiple antimicrobial agents and there are recent reports of isolates resistant to virtually all clinically relevant drugs. In the present study, the in vitro activities of tigecycline, minocycline and doxycycline against 67 MDR-AB isolates recovered from 29 burn and 38 non-burn Iranian patients hospitalised in Tehran and Tabriz, respectively, were studied. Tigecycline and minocycline may be still considered effective therapeutic options for MDR-AB infections. However, ongoing monitoring of A. baumannii susceptibility to these antibiotics is required

Anti-Cancer Effects of Probiotic Lactobacillus acidophilus for Colorectal Cancer Cell Line Caco-2 through Apoptosis Induction

Background: Colorectal cancer is one of the most common cancers worldwide. Probiotics are useful and non-pathogenic microorganisms in the gastrointestinal tract, which can show anticancer activity through the induction of apoptosis. This study aimed to evaluate the antiproliferative effects of Lactobacillus acidophilus probiotic on the Caco-2 colorectal cancer cell line. Methods: The supernatant (secreted metabolites) and bacterial extract of L. acidophilus probiotics were prepared and used as an anti-proliferative agent on the colorectal cancer cell line, Caco-2 in vitro. The effects of supernatant and extract of L. acidophilus were evaluated on the viability and proliferation of cancer cells using MTT assay. Moreover, morphological alterations of cancer cells treated with supernatant and extract of L. acidophilus were evaluated by an inverted phase contrast microscope. The mRNA expression levels of apoptosis-related genes (SURVIVIN and SMAC) in treated cancer cells and untreated controls were evaluated using the Real-Time PCR method. Results: The results showed that the supernatant and extract of L. acidophilus inhibited the viability and proliferation of cancer cells in a dose and time-dependent manner. Moreover, various morphological alterations were observed in the treated cancer cells, which are indicators of apoptosis induction. The mRNA expression of SURVIVIN and SMAC genes were significantly up-regulated and downregulated in the treated cancer cells, respectively. Conclusion: The results of the present study suggested that the supernatant and extract of L.acidophilus could inhibit the viability and proliferation of colorectal cancer cell line, Caco-2through induction of apoptosis, increase the survival rate of colon cancer patients

The SNARE Protein, Syntaxin1a, Plays an Essential Role in Biphasic Exocytosis of the Incretin Hormone, Glucagon-Like Peptide-1

Exocytosis of the hormone, glucagon-like peptide-1 (GLP-1), by the intestinal L-cell is essential for the incretin effect after nutrient ingestion, and is critical for the actions of dipeptidylpeptidase IV inhibitors that enhance GLP-1 levels in patients with type 2 diabetes. 2-Photon microscopy revealed that exocytosis of GLP-1 is biphasic, with a 1(st) peak at 1-6min and a 2(nd) peak at 7-12min after stimulation with forskolin. Approximately 75% of the exocytotic events were represented by compound granule fusion, and the remainder were accounted for by full fusion of single granules, under basal and stimulated conditions. The core SNARE protein, syntaxin-1a (syn1a), was expressed by murine ileal L-cells. At the single L-cell level, 1(st) phase forskolin-induced exocytosis was reduced to basal (p<0.05) and 2(nd) phase exocytosis was abolished (p<0.05) by syn1a knockout. L-cells from intestinal-epithelial syn1a-deficient mice demonstrated a 63% reduction in forskolin-induced GLP-1 release in vitro (p<0.001), and a 23% reduction in oral glucose-stimulated GLP-1 secretion (p<0.05) in association with impairments in glucose-stimulated insulin release (by 60%, p<0.01) and glucose tolerance (by 20%, p<0.01). Our findings therefore identify an exquisite mechanism of metered secretory output that precisely regulates release of the incretin hormone, GLP-1 and, hence, insulin secretion following a meal

Quantum Dot Reflective Semiconductor Optical Amplifiers: Optical Pumping Compared with Electrical Pumping

A comprehensive study has been conducted on quantum dot reflective semiconductor optical amplifiers (QD-RSOAs) with optical pumps (OPs). Moreover, few studies have been completed on OP-based QD-RSOAs. A comparison is made between them and QD-RSOAs with electrical pumps (EPs) in this study. It is shown that the dynamical properties of the device can significantly develop in the optical pumping version. The optical properties are studied for both methods. Moreover, by solving the coupled differential rate and signal propagation equations, the operation of the device in the pulse mode is investigated. Finally, it is proven that OP QD-RSOAs can perform significantly better in applications such as fast all-optical signal processing and wavelength division multiplexing in passive optical networks
