  • Over the past decade the topic of energy and environment has been acknowledged among many people as a critical issue to be solved in 21st century since the Kyoto Protocol came into effect in 1997. Its political recognition was put forward especially at Heiligendamm in 2007, when the effect of carbon dioxide emission and its hazard in global climate were discussed and shared universally as common knowledge.

  • Encounters with Phagocytes Phagocytosis and Inflammation Phagocytosis of microbes is a major innate host defense that limits the growth and spread of pathogens. Phagocytes appear rapidly at sites of infection in conjunction with the initiation of inflammation. Ingestion of microbes by both tissue-fixed macrophages and migrating phagocytes probably accounts for the limited ability of most microbial agents to cause disease.

  • A novel class of molecular chaperones co-ordinates the assembly and targeting of complex metalloproteins by binding to an amino-terminal peptide of the cognate substrate. We have previously shown that the NarJ chaperone interacts with the N-terminus of the NarG subunit coming from the nitrate reductase complex, NarGHI.

  • The crystal structure ofPterocarpus angolensislectin is determined in its ligand-free state, in complex with the fucosylated biantennary complex type decasaccharide NA2F, and in complex with a series of smaller oligosaccha-ride constituents of NA2F. These results together with thermodynamic binding data indicate that the complete oligosaccharide binding site of the lectin consists of five subsites allowing the specific recognition of the penta-saccharide GlcNAcb(1–2)Mana(1–3)[GlcNAcb(1–2)Mana(1–6)]Man. ...

  • The cystine-knot motif, made up of three intertwined disulfide bridges, is a unique feature of several toxins, cyclotides and growth factors, and occurs in a variety of species, including fungi, insects, molluscs and mammals. Growth factor molecules containing the cystine-knot motif serve as ligands for a diverse range of receptors and play an important role in extracellular signalling.

  • Molecular mechanics calculations on conformers of Ac-HGly-NHMe, Ac-b 2 -HAla-NHMe and Ac-b 3 -HAla-NHMe indicate that low-energy conformations of the b-amino acids backbone, corresponding to gauche rotamers around the Ca–Cbbond, may overlap canonical backbone conformers observed for a-amino acids. Therefore, Sub-stance P (SP) was used as a model peptide to analyse the structural and biological consequences of the substitution of Phe7andPhe8by(R)-b 2 -HPheandofGly9byHGly (R)-b 2 -HAla or (S)-b 3 -HAla....

  • It is my privilege to contribute the foreword for this unique volume entitled: “Plant Tissue Culture Engineering,” edited by S. Dutta Gupta and Y. Ibaraki. While there have been a number of volumes published regarding the basic methods and applications of plant tissue and cell culture technologies, and even considerable attention provided to bioreactor design, relatively little attention has been afforded to the engineering principles that have emerged as critical contributions to the commercial applications of plant biotechnologies.

  • The potential value of artificial neural networks (ANNs) as a predictor of malignancy has now been widely recognised. The concept of ANNs dates back to the early part of the 20th century; however, their latest resurrection started in earnest in the 1980s when they were applied to many problems in the areas of pattern recognition, control, and optimisation.

  • Almost since their inception, the natural sciences, those fields that use the scientific method to study nature, have been divided into two branches: the biological sciences and the physical sciences. In part, this division can be viewed as a convenient social contrivance. However, over time it has also served more functional purposes. Physical scientists, when seeking the fundamental laws, have found it necessary to focus on the simplest of systems—elementary particles, atoms, and molecules—items clearly not alive.

  • Xylanase A from the phytopathogenic bacteriumErwinia chrysanthemiis classified as a glycoside hydrolase family 30 enzyme (previously in family 5) and is specialized for degradation of glucuronoxylan. The recombinant enzyme was crystallized with the aldotetraouronic acidb-D-xylopyranosyl-(1fi4)-[4-O-methyl-a-D-glucuronosyl-(1 fi2)]-b-D-xylopyranosyl-(1 fi4)-D-xylose as a ligand.

  • The level of intracellular proteins is mainly regulated through modifications by ubiquitin ligases that target them for degradation. Members of the NEDD4 family of E3 ubiquitin ligases, such as Itch (atrophin-1 interacting protein 4), possess up to four WW domains for specific association with PY motif-containing substrates.

  • Despite increasing international recognition of the threat posed by terrorists’ use of the Internet in recent years, there is currently no universal instrument specifically addressing this pervasive facet of terrorist activity. Moreover, there is limited specialized training available on the legal and practical aspects of the investigation and prosecution of terrorism cases involving the use of the Internet. The present publication complements the existing resources developed by UNODC in the areas of counter-terrorism, cybercrime and rule of law.

  • Many risks that we face on a daily basis may be unavoidable, so there is an expectation by individuals that the level of risk is being managed and reduced to safe levels through evidence-based risk assessments and public health interventions. There has been a growing recognition that risks need to be viewed in their public health context to ensure that the most important risks are prioritized and addressed. Under a broader public health imperative, risk assessments are used as an important process to quantify the probability of harmful effects to individuals, sub-populations (eg.
