  • The explosion of new technologies in the post-genomic era is allowing the study of biological systems on a genome-wide scale, at the main functional genomic levels: (epi)-genome, transcriptome, proteome, endo- and exometabolome, and their interactions. At the same time that these techniques are being applied and refined, the complexity of biological systems is being rediscovered (1) with thousands of components (e.g., genes, transcripts, proteins, metabolites) participating in finely tuned metabolic and regulatory networks.

  • These processes also were included in early fermentation of beer.[11] These processes were introduced in early Mesopotamia, Egypt, and India, and still use the same basic biological methods. In brewing, malted grains (containing enzymes) convert starch from grains into sugar and then adding specific yeasts to produce beer. In this process, carbohydrates in the grains were broken down into alcohols such as ethanol. Later other cultures produced the process of lactic acid fermentation which allowed the fermentation and preservation of other forms of food, such as soy sauce.

  • Fujishima and Honda (1972) demonstrated the potential of titanium dioxide (TiO2) semiconductor materials to split water into hydrogen and oxygen in a photo-electrochemical cell. Their work triggered the development of semiconductor photocatalysis for a wide range of environmental and energy applications. One of the most significant scientific and commercial advances to date has been the development of visible light active (VLA) TiO2 photocatalytic materials. In this review, a background on TiO2 structure, properties and electronic properties in photocatalysis is presented.

  • The environmental science of ecology is the study of the relationship of plants andanimals to their physical and biological environment. The physical environment includeslight and heat or solar radiation, moisture, wind, oxygen, carbon dioxide, nutrients in soil,water, and atmosphere. The biological environment includes organisms of the same kindas well as other plants and animals.

  • Biotechnology (sometimes shortened to "biotech") is generally accepted as the use of living systems and organisms to develop or make useful products, or "any technological application that uses biological systems, living organisms or derivatives thereof, to make or modify products or processes for specific use" (UN Convention on Biological Diversity)[1] . For thousands of years, humankind has used biotechnology in agriculture, food production and medicine.[2] The term itself is largely believed to have been coined in 1919 by Hungarian engineer Karl Ereky.

  • 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....

  • Figure 80-6 Oncogene signaling pathways are activated during tumor progression and promote metastatic potential. This figure shows a cancer cell that has undergone epithelial to mesenchymal transition (EMT) under the influence of several environmental signals. Critical components include activated transforming growth factor beta (TGF-β) and the hepatocyte growth factor (HGF)/c-Met pathways, as well as changes in the expression of adhesion molecules that mediate cell-cell and cellextracellular matrix interactions.

  • The relative biological effectiveness of radiations of different quality is examined in detail in this report. The analyses were performed by Scientific Committee 40 of the NCRP which is charged with the responsibility for analysis and evaluation of radiobiological data relevant to radiation protection recommendations. This report is a follow-on to the previous report of Scientific Committee 40 on its evaluation of the effects of dose rate which was published in 1980 as NCRP Report No.
