background and objectives: the magnetotactic bacterium magnetospirillum gryphiswaldense (msr-1) mineralizes the magnetite (fe3 o4) crystals and organizes a highly ordered intracellular structure, called the magnetosome. iron transport system supports the biogenesis of magnetite. although iron is an essential trace element for many metabolic pathways of the body, increase or decrease in iron wil...

OBJECTIVES Radon concentrations for 31 Polish underground tourist routes were analyzed. The equivalent dose to the lung, the effective dose and the relative risk were calculated for employees of the analyzed routes on the grounds of information on radon concentrations, work time, etc. MATERIAL AND METHODS The relative risk for lung cancers was calculated using the Biological Effects of Ionizi...

MOTIVATION Automated methods for biochemical pathway inference are becoming increasingly important for understanding biological processes in living and synthetic systems. With the availability of data on complete genomes and increasing information about enzyme-catalyzed biochemistry it is becoming feasible to approach this problem computationally. In this paper we present PathMiner, a system fo...

The underrepresentation of women in engineering is often explained by gender differences in interests or abilities, learning environments and learning styles, or the uncertainty of the job market. But young women in Norway have largely overcome many of the traditional gender differences, and the job market is favourable. However, female engineering students lack role models and networks. Many l...

People v. Simpson, dubbed by many as "the trial of the century," was an expensive court case that taxed Los Angeles County's coffers. Many creative, and occasionally unconstitutional, proposals were suggested to lessen the county's hardship, but none were implemented. While the Simpson case may have captured the nation's attention, it was a poor justification to radically alter how the courts' ...

Th e Impact of Spoilers on Peace Processes and Peacebuilding M ceasefires and peace agreements in civil wars are initially unsuccessful and give way to renewed violence. In other cases, peace processes have become interminably protracted: lengthy and circular negotiations in which concessions are rare and even if agreements are reached they falter at the implementation phase. State-building and...

Research on natural products containing hexahydropyrrolo[2,3-b]indole (HPI) has dramatically increased during the past few years. Newly discovered natural products with complex structures and important biological activities have recently been isolated and synthesized. This review summarizes the structures, biological activities, and synthetic routes for natural compounds containing HPI, emphasi...

The biological and medicinal properties of 5-aminopyrazoles have prompted enormous research aimed at developing synthetic routes to these heterocyles. This review focuses on the biological properties associated with this system. Various synthetic methods developed up to 2010 for these compounds are described, particularly those that involve the reactions of β-ketonitriles, malononitrile, alkyli...

The Aizenberg lab's research is aimed at understanding some of the basic principles of biological architectures and the economy with which biology solves complex problems in the design of multifunctional, adaptive materials. The goal is to use biological principles as guidance in developing new, bio-inspired synthetic routes and nanofabrication strategies that would lead to advanced materials a...

Background & aim: Acquired immune deficiency syndrome (AIDS) is an infectious disease caused by human immunodeficiency virus (HIV). The awareness of HIV preventive measures and its transmission routes have an important role in controlling the HIV infection in the society. Regarding this, the present study aimed to investigate the awareness and attitudes of the high school students regarding HIV...
