This study was conducted to compare the impact of various organic amendments with different C/N ratios and chemical compositions on biological and chemical degradation of Atrazine in sterile and non-sterile soils. The experiment was carried out in a factorial arrangement (2×6×2) including two soil types (sterile and non sterile soils), six types of organic amendments (vermicompost, cow manure, ...
2,5-Diketopiperazines (2,5-DKPs) are an important category of structurally diverse cyclic dipeptides with prominent biological properties. These 2,5-DKPs have been obtained from a variety of natural resources, including marine organisms. Because of the increasing numbers and biological importance of these compounds, this review covers 90 marine originated 2,5-DKPs that were reported from 2009 t...
A drug's biological half-life is defined as the time required for the human body to metabolize or eliminate 50% of the initial drug dosage. Correctly measuring the half-life of a given drug is helpful for the safe and accurate usage of the drug. In this study, we investigated which gene ontology (GO) terms and biological pathways were highly related to the determination of drug half-life. The i...
Introduction: Thrombosis and the blockage of blood vessels with clots, can lead to acute myocardial infarction and some times even death. Aside from surgical interventions to remove the blockage, the only available treatment is the administration of thrombolytic agents to dissolve the blood clot. Streptokinase (SK) is the most commonly used fibrinolytic drug for this purpose. However, SK...
The importance of dispersal for the maintenance of biodiversity, while long-recognized, has remained unresolved. We used molecular markers to measure effective dispersal in a natural population of the vertebrate-dispersed Neotropical tree, Simarouba amara (Simaroubaceae) by comparing the distances between maternal parents and their offspring and comparing gene movement via seed and pollen in th...
This paper examines the rise of the ‘neoconservative’ thinkers and policymakers that have exerted such a powerful influence over the foreign policy of the administration of George W. Bush. The paper initially provides a theoretical context for thinking about American power, before detailing the activities and beliefs of some of the most prominent neocon thinkers. The key argument I make is that...
