A chimeric lambda DNA molecule containing the myosin alkali light-chain gene of Drosophila melanogaster was isolated. The encoded amino acid sequence was determined from the nucleic acid sequence of a cDNA homologous to the genomic clone. The identity of the encoded protein was established by two criteria: (i) sequence homology with the chicken alkali light-chain proteins and (ii) comparison of...

We show that alkali metals function as effective modifiers of calcium oxalate monohydrate (COM) crystallization wherein alkali-oxalate ion parings reduce the rate of crystal growth by as much as 60%. Our findings reveal a distinct trend in alkali metal efficacy that cannot be explained by colloidal theories or simple descriptors, such as ion size, but is consistent with a theoretical model that...

Calcium-alkali syndrome is characterized by hypercalcemia, renal injury and metabolic alkalosis. Calcium-alkali syndrome caused by calcium carbonate and vitamin D has been increasing in association with their growing use for the treatment and prevention of osteoporosis. Renal injury is the most critical factor determining the severity and prognosis of this syndrome. This review focuses on the m...

So far, it has been suggested that phosphoenolpyruvate carboxylases (PEPCs) and PEPC kinases (PPCKs) fulfill several important non-photosynthetic functions. However, the biological functions of soybean PPCKs, especially in alkali stress response, are not yet well known. In previous studies, we constructed a Glycine soja transcriptional profile, and identified three PPCK genes (GsPPCK1, GsPPCK2 ...

Alkali-treated lipopolysaccharide from Brucella abortus S1119.3 coupled to agarose beads by cyanogen bromide activation resulted in an immunoadsorbent with which a large amount of B. abortus-specific antibodies could be purified. The method described gave alkali-treated lipopolysaccharide binding efficiencies of up to 98%. There was little loss of alkali-treated lipopolysaccharide from the colu...

The alkali preparation of the root and fresh leaf juice of Moringa oleifera possessed significant dose -depen-dent anti-ulcer activity in experimentally induced acute gastric ulcers with aspirin, the anti-ulcer effect of the alkali preparation of the root seems to be more pronounced than that of the fresh leaf juice. Te anti-ulcer activity of the alkali preparation of the root could be due to i...

Collective surface excitations in alkali-metal overlayers are observed using photoyield spectroscopy. Spectra for Na and K on Al~111! reveal a multipole surface plasmon and bulklike overlayer plasmon. In contrast, Li on Al exhibits only the multipole mode. In the submonolayer regime, all three alkali metals provide evidence for the threshold excitation. Time-dependent density-functional calcula...

We investigate the measurement of alkali number densities using the Faraday rotation of linearly polarized light. We "nd that the alkali number density may be reliably extracted even in regimes of very high bu!er gas pressure, and very high alkali number density. We have directly veri"ed our results in potassium using absorption spectroscopy on the second resonance (4 SP5 P). 2001 Published by ...

Present study showed synthesis of novel type porous alkali niobate piezoelectric ceramics, and the formation domains photocatalytic activity for ceramics were investigated while comparing with dense to confirm enhancement domain orientation around pores. Porous Li0.06Na0.47K0.47NbO3 synthesized by a template method using polymethylmethacrylate as pore former agent. Uniform pores 6 µm in diamete...

A stability analysis of metal nanowires shows that a Jahn-Teller deformation breaking cylindrical symmetry can be energetically favorable, leading to stable nanowires with elliptic cross sections. The sequence of stable cylindrical and elliptical nanowires allows for a consistent interpretation of experimental conductance histograms for alkali metals, including both the electronic shell and sup...
