Polyclonal antibodies to synthetic human pancreatic growth hormone-releasing factor [hpGRF(1-44)NH2] and rat hypothalamic growth hormone-releasing factor [rhGRF(1-43)OH] were produced in rabbits by injecting these weak immunogens, coupled to thyroglobulin and emulsified with complete Freund's adjuvant in the presence of activated charcoal, directly into the spleen. A subsequent booster injectio...

We have previously reported purification of three forms of histamine-releasing factors (HRFs) from mixtures of streptokinase-streptodornase stimulated human mononuclear cells and platelets with apparent molecular masses of 10-12, 15-17, and 40-41 kD (1989. J. Clin. Invest. 83:1204-1210). We have also prepared mouse MAbs against the 10-12-kD HRF (1989. J. Allergy Clin. Immunol. 83:281). Affinity...

In this work, the study of various substituted Kaempferol derivatives is presented. The bond dissociation energies (BDE) have been calculated using B3LYP level and different basis sets in gas-phase. Calculated results show that the BDE values of substituted Kaempferol range from about 77 to100 kcal/mol, demonstrating that Kaempferol is an effective chain-breaking antioxidant that prevents lipid...

Medially single hip joint knee-ankle-foot orthosis (MSH-KAFO) such as the Walkabout or Primewalk is effective in restoring a stable standing posture in paraplegia. To evaluate the energy consumption of during walking with the Walkabout and the Primewalk, both using the FES system, T12 level complete paraplegic subject participated in this study. We measured oxygen consumption during self-select...

The crystal structures of the monoclinic form of Ph2P(0)NH2 and of its cesium salt, [Cs{Ph2P(0)NH}l have been determined by X-ray methods. Ph2P(0)NH2: Space group P2,/c, Z = 16, lattice dimensions (-80°C): a = 2530.2(3), b = 858.9(2), c = 2135.5(3) pm, ß = 110.78(1)°, R , = 0.055. Diphenylphosphinic acid amide forms dimeric molecules via N-H• O hydrogen bonds, the dimeric units again are associ...

Catalytic aerobic oxidation of benzyl alcohol (BnOH) to benzaldehyde (PhCHO) over supported noble metal catalysts has grabbed the attention researchers due critical role PhCHO in numerous industrial syntheses. In present study, a novel catalyst, Pd-P alloy on aminopropyl-functionalized mesoporous silica (NH2-SiO2), was prepared through situ reduction and characterized by BET-BJH analysis, SEM, ...

A strategy is presented for identification of putative neurohormones that were predicted by sequence analysis of recombinant cDNa molecules. The nucleotide sequence of a cloned calcitonin cDNA insert predicts that the proteolytic excision of calcitonin from a 136-amino acid precursor should generate two additional peptides derived from regions flanking the calcitonin sequence on the NH2 and car...

The solution structures of two human growth hormone releasing factor analogues, 27Leu45Gly-hGHRF(1-45)OH and 27Nle-hGHRF(1-29)NH2, are investigated by means of circular dichroism and nuclear magnetic resonance spectroscopy. Using circular dichroism spectroscopy, it is shown that both peptides adopt ordered structures at low concentrations of trifluoroethanol (approximately 30%). Quantitative an...

Translation of mRNA encoding vesicular stomatitis virus envelope glycoprotein G by as membrane-free ribosomal extract obtained from HeLa cells yielded a nonglycosylated protein (G1 (Mr 63,000). In the presence of added microsomal membranes, G1 was converted to the glycosylated protein (G2 (Mr 67,000) which is inserted in the membrane vesicles as a transmembrane protein. Labeling with methionine...
