Characterization of mycosporine-serine-glycine methyl ester, a major mycosporine-like amino acid from dinoflagellates: a mass spectrometry study.

Journal of phycology

Carignan MO, Carreto JI.
PMID: 27007200
J Phycol. 2013 Aug;49(4):680-8. doi: 10.1111/jpy.12076. Epub 2013 May 23.

Several unknown mycosporine-like amino acids (MAAs) have been previously isolated from some cultured species of toxic dinoflagellates of the Alexandrium genus (Dinophyceae). One of them, originally called M-333, was tentatively identified as a shinorine methyl ester, but the precise...

BACKGROUND AND OBJECTIVES: Impaired fetal growth is associated with increased cardiovascular morbidity and mortality in adulthood. We sought to determine whether adults born with intrauterine growth restriction have primary maladaptive changes in cardiac structure.METHODS: Study participants were adults (34-49...

Cancer Stem Cells in the Thyroid.

Front Endocrinol (Lausanne). 2016 Feb 29;7:20. doi: 10.3389/fendo.2016.00020. eCollection 2016.

The cancer stem cell (CSC) model posits that CSCs are a small, biologically distinct subpopulation of cancer cells in each tumor that have self-renewal and multi-lineage potential, and are critical for cancer initiation, metastasis, recurrence, and therapy-resistance. Numerous studies...

Simulation in training questionnaire design.

Nurse researcher

Mick C, Donna M.
PMID: 27702020
Nurse Res. 1994 Jan 01;1(2):52-61. doi: 10.7748/nr.1.2.52.s7.

Teaching students about the practicalities of questionnaire design and application can raise serious ethical problems if patients are involved in their research. The authors describe how the skills can be effectively taught without recourse to involving patients at all.

Glycine N-Methyltransferase Deficiency: A Member of Dysmethylating Liver Disorders?.

JIMD reports

Barić I, Erdol S, Saglam H, Lovrić M, Belužić R, Vugrek O, Blom HJ, Fumić K.
PMID: 27207470
JIMD Rep. 2017;31:101-106. doi: 10.1007/8904_2016_543. Epub 2016 May 21.

Glycine N-methyltransferase deficiency is an inherited disorder of methionine metabolism, reported so far in only four patients and characterised by permanent hypermethioninemia. This disorder has been considered as probably benign because moderate hepatomegaly in two patients was the only...

Electrochemically Induced Nanobubbles between Graphene and Mica.

Langmuir : the ACS journal of surfaces and colloids

Langmuir. 2016 Jul 05;32(26):6582-90. doi: 10.1021/acs.langmuir.6b00777. Epub 2016 Jun 21.

We present a new method to create dynamic nanobubbles. The nanobubbles are created between graphene and mica by reducing intercalated water to hydrogen. The nanobubbles have a typical radius of several hundred nanometers, a height of a few tens...

van der Waals epitaxial ultrathin two-dimensional nonlayered semiconductor for highly efficient flexible optoelectronic devices.

Nano letters

Wang Q, Xu K, Wang Z, Wang F, Huang Y, Safdar M, Zhan X, Wang F, Cheng Z, He J.

Nano Lett. 2015 Feb 11;15(2):1183-9. doi: 10.1021/nl504258m. Epub 2015 Jan 23.

Despite great progress in synthesis and application of graphene-like materials, it remains a considerable challenge to prepare two-dimensional (2D) nanostructures of nonlayered materials that may bring us surprising physical and chemical properties. Here, we propose a general strategy for...

Modeling the surface photovoltage of silicon slabs with varying thickness.

Journal of physics. Condensed matter : an Institute of Physics journal

Vazhappilly T, Kilin DS, Micha DA.
PMID: 25767101
J Phys Condens Matter. 2015 Apr 10;27(13):134204. doi: 10.1088/0953-8984/27/13/134204. Epub 2015 Mar 13.

The variation with thickness of the energy band gap and photovoltage at the surface of a thin semiconductor film are of great interest in connection with their surface electronic structure and optical properties. In this work, the change of...

Analytic model for the electrowetting properties of oil-water-solid systems.

Physical review. E

The competitive wetting of oil and aqueous electrolytes on solid surfaces depends strongly on the surface charge of the solid-water and the water-oil interface. This charge density is generally not known a priori but changes as ions adsorb or...
