  • Artificial Intelligence (AI) has been from its beginning the wave of evolution in computer science. It is in good health and a proof of it is the fact that many companies qualify its novelties as ‘smart’ or ‘intelligent’ independently of the features included in them; the term ‘society of knowledge’ has been imposed to draw society nearer to the future and a symbol of breakthrough.

  • Biological signal analysis1 encompasses several interdisciplinary topics that deal with analysing signals generated by various physiological processes in the human body. These signals could be electrical, chemical or acoustic in origin and an analysis of these signals are often useful in explaining and/or identifying pathological conditions of the human body. However, these signals in their rawest form do not provide much information and therefore, the motivation behind biological signal analysis is to extract (i.e. to reveal) the relevant information.

  • The pharmaceutical industry manufactures biological products, medicinal chemicals, botanical products, and the pharmaceutical products covered by Standard Industrial Classification Code Numbers 2831, 2833, and 2834, as well as other commodities. The industry is characterized by a diversity of products, processes, plant sizes, as well as wastewater quantity and quality. In fact, the pharmaceutical industry represents a range of industries with operations and processes as diverse as its products.

  • Although technical advances have resulted in marked improvements in the ability to diag‐ nose and surgically treat primary and metastatic brain tumors, the incidence and mortality rates of these tumors is increasing. Particularly affected are young adults and the elderly. The present standard treatment modalities following surgical resection including cranial irradia‐ tion and systemic or local chemotherapy each have limited efficacy and serious adverse side effects.

  • Antiangiogenic Therapy Understanding the molecular mechanisms that regulate tumor angiogenesis may provide unique opportunities for cancer treatment. Acquired drug resistance of tumor cells due to their high intrinsic mutation rate is a major cause of treatment failure in human cancers. ECs comprising the tumor vasculature are genetically stable and do not share genetic changes with tumor cells; the EC apoptosis pathways are therefore intact.

  • Cancer Cell Biology The treatment of most human cancers with conventional cytoreductive agents has been unsuccessful due to the Gompertzian-like growth kinetics of solid tumors (i.e., tumor growth is exponential in small tumors, with increasing doubling times as tumors expand; since conventional chemotherapeutic agents target proliferating cells, noncycling cells in large tumors are relatively resistant). Genetic instability is inherent in most cancer cells and predisposes to the development of intrinsic and acquired drug resistance. Thus, although tumors arise from a single cell (i.e.

  • The bevacizumab experience suggests that inhibition of the VEGF pathway will be most efficacious when combined with agents that directly target tumor cells. This also appears to be the case in the development of small-molecule inhibitors (SMI) that target VEGF receptor tyrosine kinase activity but are also inhibitory to other kinases that are expressed by tumor cells and important for their proliferation and survival.

  • For men with metastatic prostate cancer who are willing to accept the adverse impact on over- all survival and gynaecomastia in the hope of retaining sexual function, anti-androgen mono- therapy with bicalutamide (150 mg) 14 is appropriate. Healthcare professionals should begin androgen withdrawal and stop bicalutamide treatment in men with metastatic prostate cancer who are taking bicalutamide monotherapy and who do not maintain satisfactory sexual function.

  • Fresh-Frozen Plasma FFP contains stable coagulation factors and plasma proteins: fibrinogen, antithrombin, albumin, as well as proteins C and S. Indications for FFP include correction of coagulopathies, including the rapid reversal of warfarin; supplying deficient plasma proteins; and treatment of thrombotic thrombocytopenic purpura. FFP should not be routinely used to expand blood volume. FFP is an acellular component and does not transmit intracellular infections, e.g., CMV.

  • Anaphylactic Reaction This severe reaction presents after transfusion of only a few milliliters of the blood component. Symptoms and signs include difficulty breathing, coughing, nausea and vomiting, hypotension, bronchospasm, loss of consciousness, respiratory arrest, and shock. Treatment includes stopping the transfusion, maintaining vascular access, and administering epinephrine (0.5–1.0 mL of 1:1000 dilution subcutaneously). Glucocorticoids may be required in severe cases.

  • The population of Western countries is aging, and cancer in older aged persons is becoming increasingly common. The management of these neoplasms is a novel problem. Direct information on the outcome of cancer prevention and of cytotoxic chemotherapy in older individuals is scarce, especially for those aged 80 and over, and it is not clear whether the same process should direct medical decisions in younger and older persons. It is reasonable to assume that the benefits of cancer prevention and treatment diminish and the dangers increase with age.

  • The steady increase in industrialization, urbanization and enormous population growth are leading to production of huge quantities of wastewaters that may frequently cause environmental hazards. Raw or treated waste water is very oft en discharged to freshwaters and results in changing ecological performance and biological diversity of these systems. About 70% of water supplied ends up as wastewater and several natural water reservoirs are being contaminated by untreated sewage/industrial effl uents. This makes waste water treatment and waste water reduction very important issues....

  • The study of wetland plants has been of interest to botanists for many years, but the need to identify and understand these plants has expanded dramatically since the 1970s. At that time, ecologists began to make known the vital role that wetlands play in our landscapes. The image of wetlands has shifted from that of mosquito-ridden wastelands to natural areas of critical importance. Because the field of wetland ecology has expanded, so has the study of the plants that thrive there, and their role in ecosystem dynamics.

  • Before any water or wastewater can be treated, it must first be characterized. Thus, characterization needs to be addressed. Waters and wastewaters may be characterized according to their quantities and according to their constituent physical, chemical, and microbiological characteristics. Therefore, Part I is composed of two chapters: “Quantity of Water and Wastewater,” and “Constituents of Water and Wastewater.”

  • This book stems from the author’s experience with a variety of problems on the fate, distribution, and toxicity of organic compounds in the aquatic environment. It became increasingly clear that the procedures for investigating these problems crossed the traditional boundaries of organic and analytical chemistry, microbiology, and biology, and after many years this resulted in the idea of selecting the relevant aspects of these and writing the present book
