Modular construction for the programmed assembly of molecular crystals and liquid crystals
(Wiley Periodicals, Inc.Hüthig & Wepf Verlag, 1994-01)
This research aims to develop schemes for the programmed assembly of molecular materials. The underlying premise guiding this work is that structural information stored in the molecular constituents dictates their condensed ...
[alpha]-(2 --> 3)- and [alpha]-(2 --> 6)-Sialyltransferase activities present in three variants of Ehrlich tumor cells: identification of the products derived from N-acetyllactosamine and [beta]--Gal-(1 --> 3)-[alpha] GalNAc-(1 --> O)-Bn
(Elsevier, 1994-11-01)
We compared several sialyltransferase activities related to synthesis of O-linked and N-linked sialylglycoproteins in Ehrlich ascites tumor cells that grow normally in murine ascites, but are not adherent nor grow in tissue ...
Nucleotide sequence of a cDNA for the [beta]2 subunit isoform of Na+, K+-ATPase from human retina
(Elsevier, 1994-01-03)
Using as probe the entire human liver cDNA clone coding for the the [beta]2 subunit isoform of the Na+,K+-ATPase, which lacks the initiation codon ATG, and the entire 5'-untranslated region (Martin-Vasallo, P., Dackowski, ...
Estimation and resolution of heat capacities: Lattice heat capacity morphology
(Elsevier, 1994-10-10)
To utilize heat capacity determinations in the chemical thermodynamic region effectively, it is essential to be able to resolve the "excess" contributions, be they electronic (e.g. Schottky), magnetic, order--disorder, or ...
Spectroscopic characterization of CP26, a chlorophyll a/b binding protein of the higher plant Photosystem II complex
(Elsevier, 1994-12-30)
A spectroscopic study is presented of the minor chlorophyll a / b binding protein CP26 isolated from spinach by means of a dodecylmaltoside/betaine washing procedure. The preparations are characterized by a chlorophyll a ...
Control of gene expression at the level of translation initiation
(Elsevier, 1994-10)
Protein synthesis is controlled at the level of translation initiation. Cells rapidly respond to environmental changes by disassembly of polysomes and recruitment of specific mRNAs from inactive ribonucleoprotein particles ...
Callitachykinin I and II, two novel myotropic peptides isolated from the blowfly, Calliphora vomitoria, that have resemblances to tachykinins
(Elsevier, 1994)
Two peptides, related to the locust myotropic peptides locustatachykinin I-IV, were isolated from the blowfly Calliphora vomitoria. Whole, frozen flies were used for extraction with acidified methanol. A cockroach hindgut ...
Fatigue craze initiation in polycarbonate: study by small-angle X-ray scattering
(Elsevier, 1994-09)
The structural changes that occur during the incubation stage of tensile fatigue failure of glassy polycarbonate are investigated by means of small-angle X-ray scattering. The results are interpreted as the formation of ...
Isolation and characterization of a Forssman antigen-binding lectin from velvet bean ( Mucuna derringiana ) seeds
(Kluwer Academic Publishers; Chapman & Hall ; Springer Science+Business Media, 1994-10)
A Forssman antigen (GalNAcα1-3GalNAcβ1-3Galα1-4Galβ1-4Glcβ1-1Cer)-binding lectin has been purified from velvet bean ( Mucuna derringiana ) seeds by a combination of affinity chromatography and reversed phase HPLC. This ...
Distribution and regulation of the candidate prohormone processing enzymes SPC2 and SPC3 in adult rat brain
(Elsevier, 1994-12)
A number of candidate mammalian prohormone processing enzymes related to the yeast Kex2 endoprotease have been cloned and demonstrated to cleave several prohormone precursors at single, pairs and tetra basic amino acid ...
