  Furthermore, low-affinity sites that share no structural homology with the aforementioned sites have been described in the transmembrane domain. It has been discovered that, in α1βγ2 receptors, potentiation of GABA-activated currents by high concentrations of diazepam is biphasic, with a high- and a

  Based on its kinetic parameters and quaternary structure, R. pycnus arginase is a typical ureotelic L-arginase [2]. The Km value of the enzyme was lower than other arginases from other organisms (Table 2), including S. cerevisiae (15.7mM), B. anthracis (10mM), B. caldovelox (3.4mM), human liver (2.3

  Acknowledgments and Disclosures Introduction Over the last decade, the most visible strategy for the treatment of Alzheimer's disease (AD) has been amyloid β peptide (Aβ) immunotherapy (reviewed in [1]). Although the first efforts with Aβ immunotherapy failed to complete clinical trials [1], A

  It has been known for a while that oxygenation (the addition of oxygen) of Aβ can inhibit the formation of amyloids and diminish their cytotoxicity. Photo-oxygenation of Aβ started with fullerenes almost a decade ago by Toshima and co-workers. Later, porphyrins and polyoxometalates were used as well

  Introduction A defining feature of cancer cells is disruption of the normal controls of the cell cycle; a tumor suppressor or inhibitor may act by restricting progression of the cell cycle. P27 (also known as cyclin-dependent kinase inhibitor 1B, P27, or Kip1) is a putative cell-cycle inhibitor pro

  Results Discussion Today, enzymes play important roles in various fields. A good assay for enzyme activity is of great value, especially when it has good specificity, sensitivity, reproducibility and economy. ADK is the first identified enzyme in the metabolic pathway of adenosine salvage [15,

  Oxidative stress has recently been reported as one of the important mechanisms of toxic effect of Cd2+[43]. The mechanism of Cd2+-induced oxidative stress involves an imbalance between generation and removal of ROS in tissues and cellular components, causing damage to membranes, DNA, and proteins [4

  Introduction Mammalian Bestatin hydrochloride express the seven STAT family members STAT1, −2, −3, −4, −5A, −5B, and −6 [1], [2]. All STATs exert physiologically important roles as homo- and heterodimers [2], [3], [4]. Cytokines and growth factors activate STATs through the activation of kinases t

  Additional evidence for a putative role of COXs and 5-LOX in AD derives from pharmacological studies using inhibitors of these enzymes (for review, see Firuzi and Praticò, 2006). In addition to helping delineate the pathobiological mechanisms of AD, these results raise hope for discovering novel the

  Many reports have well documented that signaling pathways play a pivotal role in controlling longevity. The most studied of these pathways is the IGF-1 pathway [11,12]. A disruption of this pathway has been found to extend longevity in different groups of species starting from Caenorhabditis elegans
