Entanglement preparation using symmetric multiports

open access: yes, 2010
We investigate the entanglement produced by a multi-path interferometer that is composed of two symmetric multiports, with phase shifts applied to the output of the first multiport.

4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

open access: yesFEBS Letters, EarlyView.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...

The effect of distance on reaction time in aiming movements [PDF]

open access: yes, 2007
Target distance affects movement duration in aiming tasks but its effect on reaction time (RT) is poorly documented. RT is a function of both preparation and initiation.

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

open access: yesFEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

Simultaneous Determination of Three Effective Components in Different Compatibility Proportion of the Couple of Sophora flavescens-Fructus Ligustri lucidi by HPLC

open access: yesMATEC Web of Conferences, 2018
Sophora flavescens - Ligustrum lucidum has the effect of increasing the anti-cancer effect of white blood cells and treating liver fibrosis. In order to determine the optimal compatibility ratio of this drug pair, the rationality of the drug pairs in ...

The role of fibroblast growth factors in cell and cancer metabolism

open access: yesFEBS Letters, EarlyView.
Fibroblast growth factor (FGF) signaling regulates crucial signaling cascades that promote cell proliferation, survival, and metabolism. Therefore, FGFs and their receptors are often dysregulated in human diseases, including cancer, to sustain proliferation and rewire metabolism.

Modeling Instructional Best Practices: Pedagogy of College of Education Professors [PDF]

open access: yes, 2018
In light of increased accountability for K-12 student achievement, critics have questioned the quality of teachers and school principals as well as the university programs that prepare them for these roles (Lambert, 1996; Levine, 2005; Murphy, 1992 ...

Effects of motor preparation and spatial attention on corticospinal excitability in a delayed-response paradigm [PDF]

open access: yes, 2007
The preparation of motor responses during the delay period of an instructed delay task is associated with sustained neural firing in the primate premotor cortex.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

open access: yesFEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
