When electroactive nanomaterials are fully incorporated into an electrode structure, characterization of the crystallite sizes, agglomerate sizes, and dispersion of the electroactive materials can lend insight into the complex electrochemistry associated with composite electrodes. In this study, composite magnetite...

Risk-sensitive foraging in rats: the effects of response-effort and reward-amount manipulations on choice behavior.

Behavioural processes

Kirshenbaum AP, Szalda-Petree AD, Haddad NF.

Behav Processes. 2000 Jul 07;50(1):9-17. doi: 10.1016/s0376-6357(00)00088-7.

The literature on risk-sensitive foraging theory provides several accounts of species that fluctuate between risk-averse and risk-prone strategies. The daily energy budget rule suggests that shifts in foraging strategy are precipitated by changes in the forager's energy budget. Researchers...

The LNCaP human prostate cancer cell line is androgenand stromal-dependent for in vivo growth. We co-inoculated LNCaP cells with human fetal fibroblasts, isolated from prostate, bone (male), and lung (male and female) derived from 18- to 22-week-old human fetal...

Heterocyclic amines for the construction of peptoid oligomers bearing multi-dentate ligands.

Tetrahedron letters

Tetrahedron Lett. 2008 Jan 07;49(2):335-338. doi: 10.1016/j.tetlet.2007.11.047.

Peptoids are oligomers of N-substituted glycine that can be readily assembled using haloacetic acids and primary amines as synthons. Here, we report the synthesis and characterization of three new heterocyclic amines, 2-(2,2':6',2''-terpyridine-4'-yloxy) ethylamine, 2-(1,10-phenanthroline-5-yloxy) ethylamine and 8-hydroxy-2-quinolinemethylamine, and their...

Innovations (Phila). 2010 Sep;5(5):381-5. doi: 10.1097/IMI.0b013e3181f64a8e.

Large vessels recanalization is a challenge for mechanical atherectomy devices, where the lumen debulked is close in diameter to the device crossing profile, which may be only 25% to 30% of the original lumen size; so, the procedure can...

In situ profiling of lithium/Ag₂VP₂O₈ primary batteries using energy dispersive X-ray diffraction.

Physical chemistry chemical physics : PCCP

Kirshenbaum KC, Bock DC, Zhong Z, Marschilok AC, Takeuchi KJ, Takeuchi ES.
PMID: 24705594
Phys Chem Chem Phys. 2014 May 21;16(19):9138-47. doi: 10.1039/c4cp01220h.

In situ, in operando characterization of electrochemical cells can provide insight into the complex discharge chemistries of batteries which may not be available with destructive methods. In this study, in situ energy-dispersive X-ray spectroscopy (EDXRD) measurements are conducted for...

Mechanisms of Osteoblastic Bone Metastasis in Prostate Cancer: Role of Prostatic Acid Phosphatase.

Journal of the Endocrine Society

J Endocr Soc. 2019 Feb 01;3(3):655-664. doi: 10.1210/js.2018-00425. eCollection 2019 Mar 01.

Prostate cancer (PCa) preferentially metastasizes to bone, leading to complications including severe pain, fractures, spinal cord compression, bone marrow suppression, and a mortality of ∼70%. In spite of recent advances in chemo-, hormonal, and radiation therapies, bone-metastatic, castrate-resistant PCa...
