  • This book began as a collection of articles on neuropsychiatric disease, but with a clear focus on Schizophrenia, which is a poorly understood but very disabling group of brain disorders. We now recognize schizophrenia as a disorder of the brain, but despite advances in treatment options we are still a long way from having effective treatments, particularly for cognitive symptoms, and lack effective interventions and ways to prevent this disease.

  • Water pollution is the contamination of water resources by harmful wastes or toxins. This type of pollution can be dangerous to animals and plant populations in and around lakes, rivers, polluted groundwater areas or oceans, and can pose major problems for humans as well. Although natural phenomena, such as volcanoes and algae blooms, can create drastic changes in water quality, water is typically deemed polluted only when impaired by human contaminants.

  • An ecosystem is a group of animals and plants living in a specific region and interacting with one another and with their physical environment. Ecosystems include physical and chemical components, such as soils, water, and nutrients that support the organisms living there. These organisms may range from large animals to microscopic bacteria. Ecosystems also can be thought of as the interactions among all organisms in a given habitat; for instance, one species may serve as food for another. People are part of the ecosystems where they live and work.

  • Free radicals are constantly formed in living cells and removed by antioxidant defenses. Antioxidant enzymes are the main line of defense against free radicals in animal and plant cells. Uncontrolled generation ROS are involved in a number of human disease states, including diabetes and cancer due to disturbance in cellular and molecular processes including cell growth, differentiation and proliferation.

  • Introduction: Oleander (Nerium oleander and Nerium indicum) is a relatively small evergreen tree of an Indian origin, and growing in Honshu, Shikoku, Kyushu and Okinawa islands in Japan. The plant contains cardiac glycosides in its leaves, stems and flowers and is known as one of poisonous plants; poisoning and fatal cases for domestic animals and humans due to ingestion of this plant were reported [1–6]. The main toxin of oleander is oleandrin. Oleandrin can be measured using cross-reaction of an immunoassay kit for digoxin [1], TLC [2], HPLC [7, 8] and LC/MS [3, 6].

  • PLANT CELLS, UNLIKE ANIMAL CELLS, are surrounded by a relatively thin but mechanically strong cell wall. This wall consists of a complex mixture of polysaccharides and other polymers that are secreted by the cell and are assembled into an organized network linked together by both covalent and noncovalent bonds. Plant cell walls also contain structural proteins, enzymes, phenolic polymers, and other materials that modify the wall’s physical and chemical characteristics.

  • FC01 CELLS Cells are tiny building blocks that make up all living things. Cells are so small that you need a microscope to see them. ANIMAL CELL This is the control centre of the cell. It contains chromosomes with DNA instructions for all the cell’s activities, including instructions to make new cells. This is a jelly like substance, in which many of the cell’s activities, e.g. respiration and protein synthesis occur. This is a thin skin around the cell. It is selectivelt permeable, controlling what goes in and out of the cell....

  • The timing of the publication of this book couldn’t be better as we celebrate the 50th anniversary of Charles Elton’s seminal book, The Ecology of Invasions by Animals and Plants. Since this influential book was published in 1958, the study of bioinvasions has developed exponentially, alongside the exponential growth in the magnitude of the invasion problem itself. Today, bioinvasion, a highly complex ecological process and environmental concern, has become a specific branch in ecology and environmental studies, with many disciplines developing within it....

  • IN NATURAL HABITATS, plants are surrounded by an enormous number of potential enemies. Nearly all ecosystems contain a wide variety of bacteria, viruses, fungi, nematodes, mites, insects, mammals, and other herbivorous animals. By their nature, plants cannot avoid these herbivores and pathogens simply by moving away; they must protect themselves in other ways. The cuticle (a waxy outer layer) and the periderm (secondary protective tissue), besides retarding water loss, provide barriers to bacterial and fungal entry.

  • Over the past several years, scientists from the United States and around the world have been using a technique called DNA sequencing to unlock the genetic code of many different organisms. With code in hand, scientists can design sophisticated experiments that will inform our understanding of how an organism develops and functions. To date, they have carried out partial or complete DNA sequencing on human, mouse, rat, bacterial, and plant genomes. A major finding that was confirmed from these efforts is that most biologic functions are genetically conserved within and between species....

  • important regulators of biological processes in animals and plants. MiRNAs regulate gene expression at the posttranscriptional level by binding to mRNAs and either inhibit translation or modify the stability of the mRNA. Due to the important biological role of miRNAs it is of great interest to study their expression level in the cells. Furthermore, miRNAs have been associated with cancer and other diseases [1] and miRNA expression can help in the diagnosis and prognostic of human disease [2,3].

  • The major organic loading originates from human excreta, and is a complex mixture of fats, proteins, carbohydrates, lignin amino acids, sugars, celluloses, humic material and fatty acids. A large proportion of this organic material is in the form of both live and dead microorganisms which provide a large surface area (0.8-1.7 m2 g-1 ) for sorption of hydrophobic organic residues and it is within this fraction that most synthetic organic compounds are located (ROGERS 1996).
