  • Stereopsis is a vision process whose geometrical foundation has been known for a long time, ever since the experiments by Wheatstone, in the 19th century. Nevertheless, its inner workings in biological organisms, as well as its emulation by computer systems, have proven elusive, and stereo vision remains a very active and challenging area of research nowadays. In this volume we have attempted to present a limited but relevant sample of the work being carried out in stereo vision by researchers from around the world.

  • This volume has two first authors because it is a result of very intensive teamwork between the two authors. We have had three brainstorm meetings, each of approximately one week’s duration. There have been numerous pingpong games (questions–answers–new proposals etc.) on the Internet. All the chapters have major contributions from both of us. We hope that the volume therefore demonstrates a synergistic effect, reflecting the positive teamwork that is behind the volume.

  • 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).

  • The crisis has shown that securitization is heavily dependent on markets’ perceptions and could be subject to sudden bouts of illiquidity generated from investors’ concerns. Namely the consequences of the increased participation in bank funding by financial markets’ investors and the large increases in securitized assets, can led to acute liquidity crises.

  • A cellulase [endo-b-1,4-D-glucanase (EC] was iso-lated from the hepatopancreas of abalone Haliotis discus hannaiby successive chromatographies on TOYOPEARL CM-650M, hydroxyapatite and Sephacryl S-200 HR. The molecular mass of the cellulase was estimated to be 66 000 Da by SDS/PAGE, thus the enzyme was named HdEG66. The hydrolytic activity of HdEG66 toward carb-oxymethylcellulose showed optimal temperature and pH at 38Cand 6.3, respectively.

  • During cell intoxication by diphtheria toxin, endosome acidification trig-gers the translocation of the catalytic (C) domain into the cytoplasm. This event is mediated by the translocation (T) domain of the toxin. Previous work suggested that the T domain acts as a chaperone for the C domain during membrane penetration of the toxin.

  • The prokaryotic ATP-citrate lyase is considered to be a key enzyme of the carbon dioxide-fixing reductive tricarboxylic acid (RTCA) cycle. Kinetic examination of the ATP-citrate lyase from the green sulfur bacterium Chlorobium limicola (Cl-ACL), an a4b4 heteromeric enzyme, revealed that the enzyme displayed typical Michaelis-Menten kinetics toward ATP with an apparent Km value of 0.21 ± 0.04 mM. However, strong negative cooperativity was observed with respect to citrate binding, with a Hill coefficient (nH) of 0.45. ...

  • The K103N substitution is a frequently observed HIV-1 RT mutation in patients who do not respond to combinationtherapy. The drugs Efavirenz, MSC194 and PNU142721 belong to the recent generation of NNRTIs characterized by an improved resistance profile to the most common single point mutations within HIV-1 RT, including the K103N mutation. In the present study we present structural observations from Efavirenz in complex with wild-type protein and the K103N mutant and PNU142721 and MSC194 in complex with the K103N mutant.

  • We previously reported the construction and activity of a humanized, bispecific diabody (hEx3) that recruited T cells towards an epidermal growth factor receptor (EGFR) positive tumor. Herein, we describe the construction of a second functional, fully humanized, anti-EGFR bispecific diabody that recruits another subset of lymphocyte effectors, the natural killer cells, to EGFR-expressing tumor cells.

  • Human development has different meanings depending on the area we will focus on. It is the ontogenetic process of individual development for psychologists. It considers systematic psychological changes in several areas, such as motor, cognitive, emotional, social, that occur in human beings over the course of their life span. To sociologists and economists, among others, human development is the consideration of the macrolevel countries or regions and their development conditions related to human needs.

  • First and foremost, it is a book geared towards fish aquarists. And it is a heavy read with alot of chemistry and biology. To sum up the book: the author wrote the book to bring it to the reader's attention that an aquarium is a sort of (semi)closed ecosystem, and it needs to be thought of as this in order to be successful in raising the plants and animals inside the aquarium. she then describes the biological principles behind her methods of setting up and maintaining "low-tech" planted aquariums (as opposed to hi-tech, like those of takashi amano). She uses...
