Synthesis of stereochemically diverse cyclic analogs of tubulysins
, 2018 The synthesis of tubulysin analogs containing stereochemically diverse cyclic Tuv moieties is described. A tetrahydropyranyl moiety was incorporated into the Tuv unit by enantioselective hetero Diels-Alder reactions of Danishefsky's diene ...

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys
Advanced Engineering Materials, EarlyView.An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...

Actions of Cyclic AMP and Dibutyryl Cyclic AMP on the Electricl and Mechanical Activities of the Cat Small Intestine [PDF]
, 1975 Cyclic AMP and dibutyeyl cyclic AMP produced the inhibitory action on the spike activity and contraction of the cat small intestine Beta-stimulants also exhibited the inhibitory action.

Journal of Lipid Research, 1973 Isolated rat hepatocytes rapidly utilized [14C] palmitate and, in particular, synthesized large amounts of neutral lipids from palmitate. Incorporation into cellular lipids occurred at a linear rate proportional to the medium concentration of fatty acids.

Advanced Engineering Materials, EarlyView.Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

Cyclic AMP Phosphodiesterase and its Inhibitor in Slime Mould Development
, 1972 Cyclic adenosine-3′,5′-monophosphate (cyclic AMP) acts as a chemotactic factor causing cell aggregation in the slime mould, Dtctyosteltum discoideum1,2. Aggregation in this organism is the link between the growth phase and the second phase of development,

Advanced Engineering Materials, EarlyView.Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

Rabbit atrial histamine receptors and cyclic AMP
, 1982 The present study confirms the presence of H2 receptors in rabbit right and left atrium by measuring changes in cyclic AMP. Histamine produced significant increases in cyclic AMP in both atria although the increases were less in left atria.

Entropy‐Driven Design of Low‐Melting‐Point Alloys via Compositionally Complex Strategy
Advanced Engineering Materials, EarlyView.Conventional low‐melting‐point alloys (LMPAs) are limited by a narrow compositional space and inherent property trade‐offs. This review presents an entropy‐driven design strategy that overcomes these limitations, ushering in a new class of low‐melting‐point compositionally complex alloys (LMCCAs).

Advanced Engineering Materials, EarlyView.Despite benefits to storage stability and handleability of aluminum scrap, octadecyl phosphonic acid (ODPA) SAMs reduce the tensile strength of wires produced using friction‐induced recycling. Etching and methyl diphosphonic acid (MDPA) coatings, however, have little effect.
