Current health strategy has usually concentrated on the treatment of diseases after its start within a general health-care system. The way is harsh for the people. The trend of expenditures in health care will nearly undoubtedly lead to massive rises in medical expenses, likely failing the national health insurance system. The flow of healthcare would be set to change, with more critical rank involved in preventive medicine. Thus, with its focus on aging, anti-aging medicine might play a vital character in preventive medicine. For example, there are two antiaging drugs (USA) and one antiaging nutraceutical (Japan) for the human clinical trials under the approvals by Food and Drug Administration (FDA), and these tests are ongoing. The term for anti-aging clinical trials is the first time to be used approved by FDA for the clinical trial using metformin. The first example of this standard change is approval by FDA of the clinical trial for deciding the efficacy of metformin, in reducing the risk for aging-associated diseases. This book is intended to introduce these messages to ordinary people. Hopefully, people will have a better future.

The current class of amorphous Fe-based alloys, also referred to as amorphous steels, possess some outstanding physical properties, including high specific strength, elastic modulus, and excellent corrosion resistance, as well as maintaining fairly low cost. However, thermally-induced embrittlement and insufficient overall ductility are detrimental factors that prohibit amorphous steels from being widely used as structural materials for civilian and military applications. Also, the desire to continuously enlarge the physical size of amorphous alloys, which requires significant improvement of the glass formability, is another hurdle that requires more scientific understanding in order to promote their future application. Consequently, obtaining systematic and detailed characterizations of amorphous alloys from structural and electronic aspects are important for future improvements in their development. In this research, two directions are focused on in characterizing these effects. First, studying the crystallization processes can help gain insight as to the alloy''s overall stability. Measuring formation kinetics of crystalline phases that result and the atomic segregation mechanisms associated with devitrification can be employed to interpret the factors contributing to the glass formability. Second, examining the electronic and atomic structures in the vitrified state can assist in determining effects associated with bonding strength and electronic interactions among the various elements, which can be correlated with glass formability and the alloy''s fracture behavior when key elements are added to bring the alloy through the ductile-to-brittle transition. The characterization methods utilized in this research involve the complementary studies of crystallization sequences, phase identification, growth kinetics, chemical and structural analyses, as well as the atomic and electronic structure examination in the vitrified state of the alloys. Differential thermal analysis (DTA), X-ray diffraction (XRD), three-dimensional atom probe (3DAP), and conventional and analytical transmission electron microscopy (TEM) are employed to carry out these studies. Detailed investigation on the atomic and electronic structure in the undercooled amorphous region of the alloys is implemented with XRD, and electron energy loss spectroscopy (EELS).

Abstract: In 1984, Patterson and Piatetski-Shapiro constructed cuspidal distinguished representations on the three-fold covers of GL(3). Their construction is based on the work of Kazhdan and Patterson on metaplectic forms and the method of the converse theorems given by Jacquet, Piatetski-Shapiro, and Shalika. These distinguished representations can be viewed as generalizations of classical theta functions. This dissertation consists of two parts. In the first part, we apply the approach of Patterson and Piatetski-Shapiro to the case of the two fold cover of GL(2). We show that each Hecke character corresponds to a distinguished representation on the two-fold cover of GL(2). If the Hecke character is odd, then the corresponding distinguished representation is cuspidal. The same result has been obtained by Gelbart and Piatetski-Shapiro with a different approach using Weil representations. In the second part, we make progress toward generalizing the work of Patterson and Piatetski-Shapiro to the case of the four-fold cover of GL(4). The goal is to develop the relevant local Rankin-Selberg theory, adapt the converse theorem of Cogdell and Piatetski-Shapiro to the metaplectic setting and verify the analytic information needed to construct cuspidal distinguished representations by the converse theorem.

"The influences of ZnO nanoparticles on cellular responses to activation of muscarinic receptors were studied in Chinese hamster ovary cells expressing the human M3 muscarinic acetylcholine receptor. ZnO particles (20 nm) induced cytotoxicity in a time and concentration-dependent manner: following a 24 h exposure, toxicity was minimal at concentrations below 20 [mu]g/ml but virtually complete at concentrations above 28 [mu]g/ml. ZnO particles did not affect antagonist binding to M3 receptors or allosteric ligand effects, but increased agonist binding affinity while eliminating guanine nucleotide sensitivity. At a noncytotoxic concentration (10 [mu]g/ml), ZnO increased resting [Ca2+]i from 40 to 130 nM without compromising calcium homeostatic mechanisms. ZnO particles had minimal effects on inositol 1,4,5-trisphosphate (IP3)- or thapsigargin-mediated release of intracellular calcium from the endoplasmic reticulum, but strongly inhibited store operated calcium entry (capacitive calcium entry). The latter effect was seen as 1) a decrease in the plateau phase of the response and 2) a decrease in Ca2+ entry upon introduction of calcium to the extracellular medium following thapsigargin-induced depletion of calcium from the endoplasmic reticulum (EC50''s [approximately] 2 [mu]g/ml). Thus, ZnO nanoparticles interfere with two specific aspects of the M3 signaling pathway, agonist binding and store operated calcium entry"--Abstract, leaf iii.
