The B. subtilis DhelD allele rendered cells proficient in transformational recombination and moderately sensitive to methyl methanesulfonate when present in an otherwise Rec strain. The DhelD allele was introduced into rec-deficient strains representative of the a (recF strain), b (addA addB), g (recH), « (DrecU), and z (DrecS) epistatic groups. The DhelD mutation increased the sensitivity to D...

Bacillus subtilis recombination-deficient mutants were constructed by inserting a selectable marker (cat gene) into the yppB and ypbC coding regions. The yppB:cat and ypbC:cat null alleles rendered cells sensitive to DNA-damaging agents, impaired plasmid transformation (25- and 100-fold), and moderately affected chromosomal transformation when present in an otherwise Rec+ B. subtilis strain. Th...

In [BPT] wurde ein informationstheoretischer Ansatz für Systeme zur Bilderkennung vorge-stellt. Es wird eine erste Implementierung dieses Ansatzes mit vernetzten SINIX-MX2-Rech-nern beschrieben. /

A competitive enzyme-linked immunosorbent assay (C-ELISA) which detects antibodies unique to rinderpest virus (RPV) has been developed. This test can differentiate antibodies against RPV and those against peste des petits ruminants virus. The recombinant RPV hemagglutinin (H)-protein C-ELISA (recH C-ELISA) is based on the ability of a well-characterized monoclonal antibody (MAb) produced with t...

“This book provides a comprehensive guide that will help researchers and practitioners in the model-driven software development area to avoid risks and project failures that are frequently encountered in traditional and agile software projects.” -Jörg Rech, Fraunhofer Institute for Experimental Software Engineering, Germany Edited by: Jorg Rech, Fraunhofer Institute for Experimental Software En...

This experiment was conducted in Ferdowsi University of Mashhad, in 2011 to investigate the allelopathic potential of 68 medicinal and wild plant species belong to 19 plant families grown in Iran. Results showed that among examined plants, stigma and style of Crocus sativus,leaves of Artemisia kopetdaghensis, Mentha piperita, Zhumeria majdae, Frulago subvelutina, flowers bud of Eugenia caryophy...

Objective Diabetes mellitus is manifested by hyperglycaemia. Different treatments such as diets and drugs are recommended for diabetes control. For various reasons in recent years traditional plant (herbal) therapies as prescribed by indigenous systems of medicine with different mechanisms have commonly been used. The digestive enzymes such as alpha glucosidase are among these herbal remedies....
