From a strain of Bacillus subtilis a new antifungal peptidolipid complex of the iturin group was isolated. This antibiotic complex contained six lipophilic beta-amino acids with 3-amino-14-methylpentanoic acid as the predominant component. Iturin AL contains: 2 D-Asp, 1 L-Asp, 1 L-Glu, 1 L-Pro, 1 L-Ser, 1 D-Tyr and a mixture of 2.9% iso-C14-beta-amino acid, 30.7% n-C14-beta-amino acid, 15% iso-...

With the shift towards sustainable business development, many companies implement function-specific management systems, which can be certified against the corresponding management system standards. The management of the different systems, in particular the management of their documentation, is a very time consuming and costly process. In this context, the paper addresses the issue of the integr...

Abstract The evaluation of measurement uncertainty is often perceived by laboratory staff as complex and quite distant from daily practice. Nevertheless, standards such ISO/IEC 17025, ISO 15189 17034 that specify requirements for laboratories to enable them demonstrate they operate competently, are able generate valid results, require evaluated reported. In response this need, a European projec...

صخلملا The aim of this study isto examine whether radiofrequency (RF) used in cellular phone communications at a specific absorption rate (SAR) less than 1.2 w/kg could increase the spontaneous rate of sister chromatid exchanges (SCE) or elicit alterations both in the cell replication index (CRI) and mitotic index (MI) in human peripheral blood lymphocytes. Whole blood samples were obtained fro...

This contribution addresses the questions:  Why International Standards?  What is ISO?  How does ISO develop standards? The focus are the Key principles in standard development: 1. ISO standards respond to a need in the market 2. ISO standards are based on global expert opinion 3. ISO standards are developed through a multi-stakeholder process 4. ISO standards are based on a consensus Finall...

Background: Myocardial infarction (MI) is one of the most important causes of death worldwide. The effect of flunixin meglumine (FM) on MI is unknown. We investigated the protective effect of FM on the serum biochemical profile, malondialdehyde (MDA), and heart histology changes induced by isoproterenol (ISO) in adult male rats. Methods: Rats were randomly divided into four groups of six eac...

Despite measures to reduce disease transmission, a risk can occur when blood glucose meters (BGMs) are used on multiple individuals or by caregivers assisting a patient. The laboratory and in-clinic performance of a BGM system before and after disinfection should be demonstrated to guarantee accurate readings and reliable control of blood glucose (BG) for patients. In this study, an effective d...
