Background: Agile techniques recently have received attention from the developers of safety-critical systems. However, a lack of empirical knowledge of performing safety assurance techniques, especially safety analysis in a real agile project hampers further steps. Aims: In this article, we aim at (1) understanding and optimizing the S-Scrum development process, a Scrum extension with the integ...

RcsB is the response regulator of the complex Rcs two-component system, which senses perturbations in the outer membrane and peptidoglycan layer. BglJ is a transcriptional regulator whose constitutive expression causes activation of the H-NS- and StpA-repressed bgl (aryl-β,D-glucoside) operon in Escherichia coli. RcsB and BglJ both belong to the LuxR-type family of transcriptional regulators wi...

Introduction: Lower level of estrogen hormone is considered as an important factor for loss of learning and memory in postmenopausal women. Although estrogen replacement therapy is used for compensation, but long-term usage of estrogen is associated with a higher risk of hormonedependent cancers. Phytoestrogens, due to fewer side effects, have been proposed to prevent menopause-related co...

Background: Cerebral ischemia is a common and serious neurological disease. Ephedra-cinnamomi composed of Ephedra and cinnamomi is a famous herb-pair in Traditional Chinese Medicine. The aim of present study was to investigate the effect of Ephedra-cinnamomi on cerebral ischemia injury in rats. Material and methods: Four-Vessel Occlusion (4-VO) method was applied to induce global cerebral ische...

In Escherichia coli, the H-NS protein plays an important role in the structure and the functioning of bacterial chromosome. A homologous protein has also been identified in several enteric bacteria and in closely related organisms such as Haemophilus influenzae. To get information on their structure and their function, we identified H-NS-like proteins in various microorganisms by different proc...

A novel population of cells is described, located in the anterior part of the superior temporal sulcus (STSa, sometimes called STPa) of the temporal lobe in the macaque monkey. These cells respond selectively to the sight of reaching but only when the agent performing the action is seen to be attending to the target position of the reaching. We describe how such conditional selectivity can be g...

This document gives a short introduction into Spatial Equilibrium modeling with GAMS. 1. Intertemporal-Spatial Price Equilibrium Solving spatial equilibrium models by mathematical programming is pioneered by [9],[12], [11], and [13]. One of the most basic forms is the transportation problem, also known as the “Koopmans-Hitchcock” model. An example is found in the GAMS model library in trnsport....

During the last decade, the hns gene and its product, the H-NS protein, have been extensively studied in Escherichia coli. H-NS-like proteins seem to be widespread in gram-negative bacteria. However, unlike in E. coli and in Salmonella enterica serovar Typhimurium, little is known about their role in the physiology of those organisms. In this report, we describe the isolation of vicH, an hns-li...
