The term “medicinal” as applied to a plant indicates that it contains a substance or substances which modulate beneficially the physiology of sick mammals. Thousands of species of higher plants have been used by man for that purpose. Modern techniques have revealed the enormous variety and complexity of so-called secondary plant chemicals, i.e., those which do not occur in all species, but whic...

objective: ageing of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. accelerated ageing has been recognized as a good predictor of the storability of seed lots. aged seeds show decreased vigor and produce weak seedlings that are unable to survive once reintroduced into a habitat. the characteristics of the chemical composition of...

the aim of the present study is to conduct a survey of the implementation of enterprise resource planning and customer relationship management systems in iranian manufacturing and service companies. the focus of this survey is on some aspects of implementation of these systems including motivations, obstacles and problems, results obtained from implementation of these systems, criteria for sele...

The Peroxisome Proliferator Activated Receptor alpha (PPARα) is a transcription factor that plays a major role in metabolic regulation. This review addresses the functional role of PPARα in intermediary metabolism and provides a detailed overview of metabolic genes targeted by PPARα, with a focus on liver. A distinction is made between the impact of PPARα on metabolism upon physiological, pharm...

Since the first identification of renin by Tigerstedt and Bergmann in 1898, the renin-angiotensin system (RAS) has been extensively studied. The current view of the system is characterized by an increased complexity, as evidenced by the discovery of new functional components and pathways of the RAS. In recent years, the pathophysiological implications of the system have been the main focus of a...
