  • Most integral membrane proteins are targeted, inserted and assembled in the endoplasmic reticulum membrane. The sequential and potentially over-lapping events necessary for membrane protein integration take place at sites termed translocons, which comprise a specific set of membrane pro-teins acting in concert with ribosomes and, probably, molecular chaperones to ensure the success of the whole process.

  • PA-TM-RING proteins have an N-terminal protease-associated domain, a structure found in numerous proteases and implicated in protein binding, and C-terminal RING finger and PEST domains. Homologous proteins include GRAIL (gene related to anergy in leukocytes), which controls T-cell anergy, and AtRMR1 (receptor homology region-transmembrane domain-RING-H2 motif protein), a plant protein storage vacuole sorting receptor.

  • Important player for the regulation of gingival connective tissue homeostasis is the fibroblast, cell able to synthesize and breakdown the collagen fibers and other proteins from the ground substance. In vitro studies have shown that fibroblasts from human normal gingiva produce collagens type I and type III, while cells derived from gingiva of patients with chronic periodontitis failed to produce detectable amounts of type III collagen (Hammouda et al., 1980; Chavier et al., 1984, as cited in Bartold & Narayanan, 2006)....

  • Undergraduate biomedical engineering programs and curricula are being rapidly developed across the United States. We perceive a correspondingly increasing need for biomedical engineering textbooks specifically designed for undergraduate readers. Many educators have come to appreciate that physiology and biology are not narrow, specialized applications to be ‘‘tacked onto’’ an engineering curriculum, but are instead rich subjects that can naturally elicit and benefit from the kinds of creative problem-solving and quantitative analyses that are hallmarks of engineering.

  • They use geological and distribution data on the island’s 1,284 plant genera and more than 2,000 endemic plant taxa to identify 19 biomes there, and they describe complex conservation challenges. The next chapter by Benny Chan and Pei-Fen Lee explores the biogeography of the barnacles of Taiwan, relating taxon distributions to coastal geomorphology and the complex array of oceanic currents around the island. Global climate changes in ocean water temperature may permit southerly, warmwater taxa to expand northward, invading habitat presently occupied by coldwater taxa....

  • Telomeres, located at the ends of linear chromosomes, are essential for genome stability and integrity. Advances in telomere researches have linked telomere dysfunction with cellular aging and a number of age-related human diseases. Recent studies further expanded our knowledge of telomere functions - telomeres are shown to be important for microbial pathogen virulence and telomere proteins have important non-telomeric cellular functions.

  • Homologous recombination (HR) serves to eliminate deleterious lesions, such as double-stranded breaks and interstrand crosslinks, from chromosomes. HR is also critical for the preservation of replication forks, for telomere maintenance, and chromosome segregation in meiosis I. As such, HR is indispensable for the maintenance of genome integrity and the avoidance of cancers in humans. The HR reaction is mediated by a conserved class of enzymes termed recombinases.

  • The main objective of the Citizen's Charter is to improve the quality of public services. This is done by letting people know the mandate of the Corporation, how one can get in touch with its officials, what to expect by way of services and how to seek a remedy if something goes wrong. The Citizen’s Charter does not by itself create new legal rights, but it surely helps in enforcing existing rights.

  • Since the discovery of hepatitis C virus (HCV) in 1989, there has been an explosion of research and information on the virus. This is evidenced by the more than 20 000 papers onHCV(as of December, 2000), as well as the numerous reviews in journals and edited books. The purpose of this book is to present an overview of the diVerent disciplines that have contributed to an understanding of the virus, its diseases, current and proposed treatments, and much more.

  • Heterogeneity of information sources: Data may originate at a few authoritative sources, or alternatively, every participant might be allowed (or expected) to contribute data to the community. The level of heterogeneity of the data influences the degree to which a system can ensure uniform, global semantics for the data. A P2P system might impose a single schema on all participants to enforce uniform, global semantics, but for some applications this will be too restrictive.
