The phase behavior of aqueous mixtures of the "clouding" polymer ethyl(hydroxyethyl)cellulose (EHEC) mixed with colloidal particles and surfactants has been studied. These types of mixtures are important in many technical formulations. Two types of particles, polystyrene latex and silica, and two types of EHEC, nonmodified EHEC (N-EHEC) and hydrophobically modified EHEC (HM-EHEC), were studied. Th
We suggest a method that can be used for analysing an emergency response system. Both the literature and empirical findings indicate that response operations sometimes diverge from existing plans when adapting to an event and its consequences. The method, which aims at achieving a better understanding of emergency response management, adopts a systems perspective using various relationships that e
Insulin NPH (neutral protamine hagedorn) has for long been one of the most important therapeutic formulations for the treatment of diabetes. The protracted action profile of NPH formulations is gained from crystallizing insulin with zinc in the presence of the basic poly-arginine peptide protamine. In spite of its long history and successful use, the binding mode of the insulin-protamine complex i
The proper use and exchange of the right packaging-related information in a grocery supply chain is critical to achieve an efficient and responsive packaging logistics system. The use of well-defined packaging-related information that is available for all actors in the supply chain also facilitates an integrated and supply chain-orientated packaging development. The objective of this paper is to d
Recent results concerning the short-term growth response to salinity of the developing barley leaf are reviewed. Plants were grown hydroponically and the growth response of leaf 3 was studied between 10 min and 5 d following addition of 100 mM NaCl to the root medium. The aim of the experiments was to relate changes in variables that are likely to affect cell elongation to changes in leaf growth.
Objective To describe the effect of vaginal delivery with no clinically recognized sphincter tear on endosonographic anal sphincter morphology and sphincter pressure and to relate endosonographic results to anal sphincter pressure and anal incontinence score. Study design Thirty-two nullipara underwent anal endosonography and anal manometry in the third trimester of pregnancy, 2 weeks and 6 mon
MreB forms a cytoskeleton in many rod-shaped bacteria which is involved in cell shape determination and chromosome segregation. PCR-based and Southern analysis of various actinomycetes, supported by analysis of genome sequences, revealed mreB homologues only in genera that form an aerial mycelium and sporulate. We analysed MreB in one such organism, Streptomyces coelicolor. Ectopic overexpression
Objective - ADP plays an important role in platelet aggregation by activating P2Y(12) receptors. We assessed the hypothesis that P2Y(12) receptors are expressed in vascular smooth muscle cells (VSMC). Methods and Results - P2Y(12) receptor mRNA was found to have a high expression among the P2 receptors in human VSMC, significantly higher than the other 2 ADP receptors (P2Y(1) and P2Y(13), real-tim

The effect of some environmentally relevant factors including salinity, pH, and humic acids on the availability of bisphenol A (BPA) was evaluated by using the negligible-depletion solid-phase microextraction (nd-SPME) biomimetic method. With the variation of salinity (0-500 mM NaCl) and pH (5.0-8.5) of aqueous solutions, the partition coefficients of BPA between the nd-SPME fiber and the aqueous
The implementation of the Rio protocol and the preservation of biodiversity at national and regional level is an important step in achieving a sustainable forestry. This is indeed a challenging task since our knowledge of the ecology and habitat demands for but a few species is severely restricted. Research in the last years show that forest species have very different qualitative and spatial dema
As computational Grids move away from the prototyping state, reliability, performance and ease of use and maintenance become focus areas of their adoption. In this paper, we describe ARC (Advanced Resource Connector) Grid middleware, where these issues have been given special consideration. We present an in-depth view of the existing components of ARC, and discuss some of the new components, funct
The synthesis of two galabioside (Golalpha1-4Gal) collections based on diversification at the O-1 and O-3' atoms is reported. The galabiosides were evaluated as inhibitors of hemagglutination of human erythrocytes by two strains of Escherichia coli that expressed the class I and class II PapG adhesins, respectively. The class I adhesin. was found to prefer aromatic substituents both at the O-1 and
Clinical trials of pharmaceuticals have been running in Russia for more than ten years and while it is an attractive location for research, it remains a largely untapped resource as researchers look to expand patient recruitment outside the Western world. While academic sites like Moscow, St Petersburg and Novosibirsk have all gained experience in clinical trials, smaller hospitals in peripheral
Most literature on international cooperation focuses on the phase leading up to the signing of a treaty, while neglecting the dynamics of bargaining in the aftermath of an international agreement. Reviewing existing literature, we find that bargaining theory deals almost exclusively with the pre-agreement phase and that the enforcement and management schools in the study of compliance are predomin
In this first clinical trial liposome-encapsulated iodixanol, CT particles (CTP) were studied. The aims of the present trial were to assess the efficacy of CTP in CT and to determine the safety of different doses of CTP. A total of 47 healthy volunteers were enrolled in the present study. The CTP was administered at doses 10, 30, 70 and 100 mg encapsulated I/kg bw. Efficacy was assessed using sing
