  • Fish are aquatic vertebrates with fins for appendages. They "breathe" by means of gills. Fish make up the largest of the vertebrate groups with over 20,000 species. They can be found in a great variety of lakes, streams, oceans and estuaries. Fish are divided into two groups based on the composition of their skeletons. The sharks, skates and rays are cartilaginous fish. Their skeletons are made of cartilage, the same flexible material in your ear lobes and nose. The majority of fish have skeletons made of bone and are called bony fish....

  • Nowadays it is difficult to imagine an area of knowledge that can continue developing without the use of computers and informatics. It is not different with biology, that has seen an unpredictable growth in recent decades, with the rise of a new discipline, bioinformatics, bringing together molecular biology, biotechnology and information technology.

  • Diabetes Mellitus The success of islet cell and pancreas transplantation provides proof of concept for a cell-based approach for type I diabetes. However, the demand for donor pancreata far exceeds the number available, and maintenance of long-term graft survival remains a problem. The search for a renewable source of stem cells capable of regenerating pancreatic islets has therefore been intensive. Pancreatic βcell turnover occurs in the normal pancreas, although the source of the new βcells is controversial.

  • Harrison's Internal Medicine Chapter 107. Transfusion Biology and Therapy Blood Group Antigens and Antibodies The study of red blood cell (RBC) antigens and antibodies forms the foundation of transfusion medicine. Serologic studies initially characterized these antigens, but now the molecular composition and structure of many are known. Antigens, either carbohydrate or protein, are assigned to a blood group system based on the structure and similarity of the determinant epitopes.

  • Petroleum-based industrial products have gradually replaced products derived from biological materials. However, biologically based products are making a comeback--because of a threefold increase in farm productivity and new technologies. Biobased Industrial Products envisions a biobased industrial future, where starch will be used to make biopolymers and vegetable oils will become a routine component in lubricants and detergents.

  • Competing geophysical/geochemical hypotheses for how Earth’s surface became oxygenated – organic carbon burial, hydrogen escape to space, and changes in the redox state of volcanic gases – are examined and a more biologically-based hypothesis is offered in response. It is argued that compared to the modern oxygenated world, organic carbon burial is of minor importance to the accumulation of oxygen in a mainly anoxic world where aerobic respiration is not globally significant. Thus, for the Paleoproterozoic Great Oxidation Event (GOE) ~ 2.

  • In 2007, the National Research Council (NRC) released a report titled Toxicity Testing in the 21st Century: A Vision and a Strategy. That report pro- posed a new paradigm for toxicity testing that envisioned evaluation of biologi- cally significant perturbations in key toxicity pathways by using new methods in molecular biology, bioinformatics, and computational toxicology and a compre- hensive array of in vitro tests based primarily on human biology. The revolution in toxicity testing is under way, and a large influx of new data is anticipated. The U.S.

  • In this paper, we demonstrate three NLP applications of the BioLexicon, which is a lexical resource tailored to the biology domain. The applications consist of a dictionary-based POS tagger, a syntactic parser, and query processing for biomedical information retrieval. Biological terminology is a major barrier to the accurate processing of literature within biology domain. In order to address this problem, we have constructed the BioLexicon using both manual and semiautomatic methods. We demonstrate the utility of the biology-oriented lexicon within three separate NLP applications. ...

  • A simple and sensitive spectrophotometric method has been developed for the determination of arsenic using variamine blue as a chromogenic reagent. The method is based on the reaction of arsenic(III) with potassium iodate in acid medium to liberate iodine, which oxidizes variamine blue to form a violet coloured species having an absorption maximum at 556 nm.

  • Gossypol, a yellow pigment, isolated from cotton seeds, exhibits many interesting biological activities: antitumor, antimalarial, anti-HIV [1]. But gossypol is toxic and this toxicity may be related to the two-functional aldehyde groups [2]. Many authors prepared the Schiff’s’ base adducts of gossypol from 1985 to 2002, but these authors did not pay attention to the factor that these adducts may present under or the imine form or the enamine one.
