  • Immune-Mediated Reactions Acute Hemolytic Transfusion Reactions Immune-mediated hemolysis occurs when the recipient has preformed antibodies that lyse donor erythrocytes. The ABO isoagglutinins are responsible for the majority of these reactions, although alloantibodies directed against other RBC antigens, i.e., Rh, Kell, and Duffy, may result in hemolysis. Acute hemolytic reactions may present with hypotension, tachypnea, tachycardia, fever, chills, hemoglobinemia, hemoglobinuria, chest and/or flank pain, and discomfort at the infusion site.

  • 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 sequencing of the genome ofRalstonia solanacearum[Salanoubat M, Genin S, Artiguenave F,et al.(2002) Nature415, 497–502] revealed several genes that putatively code for polyphenol oxidases (PPOs). This soil-borne pathogenic bacterium withers a wide range of plants. We detected the expression of two PPO genes (accession numbers NP_518458 and NP_519622) with high similarity to tyrosinases, both containing the six conserved histidines required to bind the pair of type-3 copper ions at the active site....

  • The very latest research is uncovering a stream of evidence revealing evolution in action - from the actual observation of a species splitting into two, to new fossil discoveries, to the deciphering of the evidence stored in our genome. Why Evolution is True weaves together the many threads of modern work in genetics, palaeontology,geology, molecular biology, anatomy, and development to demonstrate the 'indelible stamp' of the processes first proposed by Darwin. It is a crisp, lucid, and accessible statement that will leave no one with an open mind in any doubt about the truth of evolution....

  • During development, cells and tissues undergo dynamic changes in pattern and form that employ a wider range of physical mechanisms than at any other time during an organism’s life. Biological Physics of the Developing Embryo presents a framework within which physics can be used to analyze these biological phenomena. Written to be accessible to both biologists and physicists, major stages and components of biological development are introduced and then analyzed from the viewpoint of physics. The presentation of physical models requires no mathematics beyond basic calculus.

  • Having private health insurance obviously also improves access to needed care at the right time if no other form of health coverage is available and “safety-net” providers (who provide services irrespective of ability to pay) are in the minority. In the United States, there is evidence suggesting that uninsured individuals wait to receive treatment until they need emergency care – for which hospitals are under an obligation to provide services to those in need – but obtain less primary and preventative services (Docteur et al., 2003).

  • It would have been much easier for me to write this ACKNOWLEDGEMENT if I were a well established scientist of international fame. I could then write in a pastoral manner about sweet recollections of the past, starting with a certain scientist, also internationally famous of course, who came to visit my lab and suggested that I should write such a book. Knowing that the whole world was watching and waiting, I had set aside all the other very important works and devoted most of my time to the writing of this path-blazing masterpiece.

  • Socioeconomic status, poverty, and race have been found to be correlated with ACSC rates [8-10]. Several studies have examined the associations between ACSCs and demographics using small areas of analysis (typically ZIP code) and have found that ACSCs are higher in lowincome areas and areas with higher concentrations of racial and ethnic minorities [11,12]. The elderly population has not been studied much in this context, because they are thought to be relatively well-insured.

  • In the international geographic information community one of the contemporary challenges is to develop and deploy distributed technology solutions that provide means for accessing, exploring, and utilizing distributed geographic information and geoprocessing resources over a communication network like the Internet; anywhere, anytime, and with any device. Today, the scientific research and industry development put special emphasis on interoperable geographic information services; henceforth referred to as GI services.

  • Developments in, and availability of, new production technologies which have reduced the cost and time necessary to make illegal copies of goods have played a part in this growth. This has contributed to growth in markets for counterfeit goods as the amount and range of products create increased profits for those involved in this activity (Savona and Mignone, 2004).

  • Community Action Items: The general systems com- munity should think more about building tools to help users estimate their resource needs. Perhaps users in a shared environment will have access to a best-effort staging ground where they will be able to gauge their re- source usage. One can imagine future research tools (ei- ther modeling or analysis) that attempt to capture the re- source profile of a wide-area application. Such tools are an open area for ongoing and future research [10].

  • The Oracle Internet Directory (OID) was introduced with Oracle8i. OID serves the same function as Oracle Names in that it gives users a way to connect to an Oracle Server without having a client-side configuration file. However, OID differs from Oracle Names in that it is an LDAP (Lightweight Directory Access Protocol) direc- tory; it does not merely support the Oracle-only Oracle Net protocol. Oracle Connection Manager Each connection to the database takes up valuable network resources, which can impact the overall performance of a database application.
