The anti‐prion RNA aptamer R12 disrupts the Alzheimer's disease‐related complex between prion and amyloid β

open access: yesThe FEBS Journal, 2019
The neurodegenerative disorder Alzheimer's disease (AD) is associated with the accumulation of misfolded proteins. Some recent studies suggested that amyloid beta (Aβ) forms soluble oligomers, protofibrils, and fibrils; the Aβ oligomers being more toxic ...

Quark Mass Hierarchies, Flavor Mixing and Maximal CP-Violation [PDF]

open access: yes, 1998
Flavor mixing and the quark mass spectrum are intimately related. In view of the observed strong hierarchy of the quark and lepton masses and of the flavor mixing angles it is argued that the description of flavor mixing must take this into account.

Physiological and biochemical changes and storage potential of chickpea (Cicer arietinum L.) seeds harvested at different maturation stages [PDF]

open access: yesJournal of Seed Science
: Chickpea (Cicer arietinum L.) cultivation in Brazil has expanded as a winter or second-crop option, increasing demand for superior quality seeds. This study evaluated physiological performance, biochemical parameters and storability of BRS Aleppo seeds

Vacuum vertices and the ghost-dilaton [PDF]

open access: yes, 1995
We complete the proof of the ghost-dilaton theorem in string theory by showing that the coupling constant dependence of the vacuum vertices appearing in the closed string action is given correctly by one-point functions of the ghost-dilaton.

“Disruptor” residues in the regulator of G protein signaling (RGS) R12 subfamily attenuate the inactivation of Gα subunits

open access: yesScience Signaling, 2018
Specific amino acids within RGS proteins may encode specificity toward G protein α subunits. Designing specificity Once an agonist binds to its G protein–coupled receptor, GTP replaces GDP on the α subunit of an associated G protein, which then ...

Hypernetted-chain study of broken rotational symmetry states for the $\bm{\nu}$ = 1/3 fractional quantum Hall effect and other fractionally filled Landau levels [PDF]

open access: yes, 2001
We investigate broken rotational symmetry (BRS) states for the fractional quantum Hall effect (FQHE) at 1/3-filling of the valence Landau level (LL). Recent Monte Carlo calculations by Musaelian and Joynt [J. Phys.: Condens.\ Matter {\bf 8}, L105 (1996)]

Equation of motion for relativistic compact binaries with the strong field point particle limit : the second and half post-Newtonian order [PDF]

open access: yes, 2001
We study the equation of motion appropriate to an inspiralling binary star system whose constituent stars have strong internal gravity. We use the post-Newtonian approximation with the strong field point particle limit by which we can introduce into ...

Transduction of Recombinant M3-p53-R12 Protein Enhances Human Leukemia Cell Apoptosis

open access: yesJournal of Cancer, 2016
Tumor suppressor protein p53 plays important roles in initiating cell cycle arrest and promoting tumor cell apoptosis. Previous studies have shown that p53 is either mutated or defective in approximately 50% of human cancers; therefore restoring normal ...

A Study of Evaporation Heat Transfer Coefficient Correlations at Low Heat and Mass Fluxes for Pure Refrigerants and Refrigerant Mixtures [PDF]

open access: yes, 1993
An average R12 refrigerant correlation has been developed for the mass flux range of 25-100 kg/m2-s and the heat flux range of 2-10 kW/m2. Refrigerant mixtures of 80% R22/lO% R141b and 65% R22/35% R123 have also been tested over asjrniJar range of ...
