To assess functional importance of the residues in the amino- and carboxyl-termini of crustacean hyperglycemic hormone in the mud crab Scylla olivacea (Sco-CHH), both wild-type and point-mutated CHH peptides were produced with an amidated C-terminal end. Spectral analyses of circular dichroism, chromatographic retention time, and mass spectrometric analysis of the recombinant peptides indicate ...

Hexose sugars, such as glucose and fructose produced in plants, are ubiquitous in most organisms and are the origin of most of the organic matter found in nature. To be utilized, hexose sugars must first be phosphorylated. The central role of hexose-phosphorylating enzymes has attracted the attention of many researchers, leading to novel discoveries. Only two families of enzymes capable of phos...

The question, reported in the title of this editorial, has the purpose of being intentionally a little provocative. It is obvious the Ethical Committees (CE), founded and established to approve clinical trials of new drugs that the pharmaceutical industry intends to market and, in general, biomedical research such as pharmaceutical no profit controlled clinical trials and observational studies,...

Closed expressions for the Green function and amplitude of the scalar particle scattering in the external gravitational field gμν(x) are found in the form of functional integrals. It is shown that, as compared with the scattering on the vector potential, the tensor character of the gravitational field leads to a more rapid increase of the cross section with increasing energy. Discrete energy le...

The Asr gene family (named after abscisic acid, stress and ripening), currently classified as a novel group of the LEA superfamily, is exclusively present in the genomes of seed plants, except for the Brassicaceae family. It is associated with water-deficit stress and is involved in adaptation to dry climates. Motivated by separate reports depicting ASR proteins as either transcription factors ...

The inelasticity of the secondary muon. in high-energy neutrino interactions, defined in a manner appropriate for the deep-mine cosmic-ray experiments, is computed. On the basis of the hypothesis of locality of the Iepton current, < E,/EV> = 0 0 62 f 0.12. (Submitted to Nuovo Cimento.) * Work supported by the U. S. Atomic Energy CGmmission. In order to interpret underground cosmic-ray neutrino ...
