Recent astronomical observations of high redshift quasars, dark matter-dominated galaxies, mergers neutron stars, glitch phenomena in pulsars, cosmic microwave background and experimental data from hadronic colliders do not rule out, but they even support the hypothesis that energy-density our universe most likely is upper-limited by $\rho^{uni}_{max},$ which predicted to lie between $2$ $3$ nu...

Adenosine 5'-phosphate was synthesized with 3H or 14C label specifically located as [1'-3H]AMP, [1'-14C] AMP, [5'-3H]AMP, and [5'-14C]AMP. The synthesis was accomplished from adenine and glucose or adenine and ribose using enzymes from the pentose pathway and/or from the purine salvage pathways. Structural analysis of the compounds confirmed the locations of the radiolabels. The methods provide...

Abstract. Variations in precipitation and atmospheric N deposition affect water availability desert thus may have significant effects on ecosystems. Haloxylon ammodendron is a dominant plant Asian desert, addressing its physiological acclimatization to the changes can provide insight into how plants adapt extreme environments by adjustment. Carbon isotope ratio (δ13C) has been suggested as sens...

Abstract. Variations in precipitation and atmospheric N deposition affect water availability desert thus may have significant effects on ecosystems. Haloxylon ammodendron is a dominant plant Asian desert, addressing its physiological acclimatization to the changes can provide insight into how plants adapt extreme environments by adjustment. Carbon isotope ratio (?13C) has been suggested as sens...

Management of sugar beet damping off and root rot diseases caused by Sclerotium rolfsii is urgently needed. Therefore, antifungal activities 13 materials including 2 bio agents, seaweeds, 3 chemical inducers 6 fungicides were evaluated. Required inoculum potential either fungal mass or sclerotia to reach more than 50% disease incidence was firstly investigated. Fungal inoculation (40-500...

Abstract. Multidimensional, heteronuclear NMR relaxation methods are used extensively to characterize the dynamics of biological macromolecules. Acquisition datasets on proteins typically requires significant measurement time, often several days. Accordion spectroscopy offers a powerful means shorten rate measurements by encoding “relaxation dimension” into indirect evolution period in multidim...

Amphetamine (AMP), an indirectly acting psychostimulant approved for the treatment of attention-deficit/hyperactivity disorder (ADHD) in children, adolescents, and adults, is among the most long-standing therapeutic agents in all of clinical psychopharmacology. This review focuses on AMP absorption, metabolism, and elimination brought to bear on comparative pharmacokinetics in its various formu...

Initial rate kinetics, product inhibition patterns, and equilibrium kinetics all indicate that cleavage of adenylosuccinate (AMP-S) by yeast adenylosuccinate lyase proceeds primarily by a reaction in which fumarate leaves the enzyme before AMP and cannot bind to free enzyme at kinetically significant concentrations. The alternate path, in which AMP leaves first, could be detected at equilibrium...
