Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Liquid Phase Transmission Electron Microscopy: A Window into the Early Stages of Complex Material Formation

Advanced Functional Materials, EarlyView.
Liquid‐phase transmission electron microscopy enables direct observation of nucleation and growth processes in solution. This review is dedicated to the remembrance of Helmut Cölfen and highlights recent studies on complex materials—oxides, biominerals, organic–inorganic crystals—which were central to his research activity. It summarizes key milestones,

Human Gut Bacteria and Lipidic Nanoparticles: Particle Composition Predicts Structural Transformation and Bacterial Biocompatibility

Advanced Functional Materials, EarlyView.
Lipidic nanoparticles (LNPs) were incubated with 21 gut bacteria frequently associated with the human microbiome. SAXS revealed that ∼75% of tested species induced structural transformations in monoolein LNPs, whereas phytantriol and phospholipid formulations remained unaffected.

Species specificity of streptokinase

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1983
Streptokinase, a bacterial protein, forms a complex with human plasminogen which results in a conformational change in the plasminogen molecule and the exposure of an active center. The plasminogen-streptokinase complex is an activator of plasminogen and is rapidly converted to a plasmin-streptokinase complex which, in the human, is also an activator ...

Species Specificity of Prolactin

Nature, 1966
HUMAN parathormone1,2, ACTH3,4, insulin and glucagon5 are comparatively easy to determine immunologically because antisera with high activity against the corresponding mammalian hormone preparations also give a definite immune reaction with the human hormones.

Studies on Species Specificity

The Journal of Immunology, 1964
Summary Species-specific antigens were described which are present in fractions of mammalian tissues prepared by extraction at 100°C. followed by precipitation by ethanol (BE fractions). Interspecies cross-reactions were rather weak; they were more pronounced in closely related species, e.g., man and Rhesus monkey, than in distant ...

Species specificity of informatin

Molecular Biology Reports, 1977
Informatin, the protein moiety of nuclear pre-mRNA containing particles, exhibits species specific antigenic properties but shows also some interspecies cross-reactivities.

Species specificity in protein synthesis

Journal of Molecular Biology, 1967
The phenomenon of species specificity in poly U-directed cell-free protein synthesis (whereby combinations of ribosomes of one organism with supernatant enzymes from a different one are sometimes inactive) was studied in the case of the amino acid-incorporating systems prepared from Escherichia coli, Bacillus subtilis, Saccharomyces cerevisiae ...

Species Specificity of Tissue Thromboplastin

Haemostasis, 2009
The species specificity of thromboplastin (tissue factor) is an important fact to take into consideration when clotting assays or experiments are planned. We have (re)investigated all possible combinations of thromboplastin and plasma from several of the most commonly used species of experimental animals.

Species-specific and Non-species-specific Elemental Trends in Tree Rings

Doklady Earth Sciences, 2021
The goal was to find out how consistent the elemental distributions in tree rings are. The dataset was received for a long-term afforestation experiment that included even soil conditions and a variety of conifers (Scots pine, Norway spruce, Siberian pine, and Siberian larch) growing in pure stands.
