  • The metastable state of liquids which are supercooled has been the subject of interest for over 300 years. Supercooled water and aqueous solutions are found in the atmosphere, in cold-hardy organisms, and in many industrial applications. For example, freeze tolerance and the associated avoidance of supercooling, is the dominant cold-related strategy in Southern Hemisphere insects, being found in 77% of cold hardy insects. In industry, thermodynamic systems such as cool boxes have a significant financial driving force for supercooling to be controlled and this is also covered in this book....

  • Cushing’s disease is rare in children and adolescents. We report the clinical presenta- tions of three children with Cushing’s disease. All three exhibited the typical symptoms and signs of weight gain and growth retardation. Two also demonstrated personality changes, hypertension and hypokalemia, the last of these being rarely reported in patients with Cushing’s disease. Lack of diurnal changes in serum cortisol levels was the most common biochemical finding.

  • Previously, we demonstrated apoptotic cell death in the chorion laeve trophoblast layer of human fetal membrane tissues during the late stages of pregnancy, the progression of apoptosis during incubation in vitro, and its suppression by a low concentration of glucocorticoid hormones.

  • Digital Image Processing The electronic camera/frame grabber/computer combination has made it easy to digitize, store and manipulate images. These possibilities have made a great impact on optical metrology in recent years. Digital image processing has evolved as a specific scientific branch for many years. Many of the methods and techniques developed here are directly applicable to problems in optical metrology. In this chapter we go through some of the standard methods such as edge detection, contrast stretching, noise suppression, etc.

  • A∗ parsing makes 1-best search efficient by suppressing unlikely 1-best items. Existing kbest extraction methods can efficiently search for top derivations, but only after an exhaustive 1-best pass. We present a unified algorithm for k-best A∗ parsing which preserves the efficiency of k-best extraction while giving the speed-ups of A∗ methods. Our algorithm produces optimal k-best parses under the same conditions required for optimality in a 1-best A∗ parser.

  • Akt regulates various cellular processes, including cell growth, survival, and metabolism. Recently, Akt's role in neurite outgrowth has also emerged. We thus aimed to identify neuronal function-related genes that are regulated by Akt. Methods: We performed suppression subtractive hybridization on two previously established PC12 sublines, one of which overexpresses the wild-type (WT) form and the other, the dominant-negative (DN) form of Akt. These sublines respond differently to NGF's neuronal differentiation effect. Results: A...

  • Diffuse noxious inhibitory controls (DNIC) can be produced by different types of conditioning stimuli, but the analgesic properties and underlying mechanisms remain unclear. The aim of this study was to differentiate the induction of DNIC analgesia between noxious electrical and inflammatory conditioning stimuli. Methods: First, rats subjected to either a supramaximal electrical stimulation or an injection of high-dose formalin in the hind limb were identified to have pain responses with behavioral evidence and spinal Fos-immunoreactive profiles. Second, suppression of tail-flick...

  • The molecular response to hypoxia stress in aquatic invertebrates remains relatively unknown. In this study, we investigated the response of the Pacific oyster Crassostrea gigasto hypoxia under experimental conditions and focused on the analysis of the differential expression patterns of specific genes associated with hypoxia response. A suppression subtractive hybridiza-tion method was used to identify specific hypoxia up- and downregulated genes, in gills, mantle and digestive gland, after 7–10 days and 24 days of exposure....

  • The effects of pesticide contamination on the metabolism of marine mol-luscs are poorly documented. We investigated the response of a marine bivalve, the Pacific oyster,Crassostrea gigas, using a suppression subtrac-tive hybridization method to identify up- and down-regulated genes after a 30-day exposure period to herbicides (a cocktail of atrazine, diuron and isoproturon, and to the single herbicide glyphosate). A total of 137 unique differentially expressed gene sequences was identified, as well as their asso-ciated physiological process....
