Scientific reports

Gamaletsos PN, Godelitsas A, Kasama T, Kuzmin A, Lagos M, Mertzimekis TJ, Göttlicher J, Steininger R, Xanthos S, Pontikes Y, Angelopoulos GN, Zarkadas C, Komelkov A, Tzamos E, Filippidis A.
PMID: 26899139
Sci Rep. 2016 Feb 22;6:21737. doi: 10.1038/srep21737.

We present new data about the chemical and structural characteristics of bauxite residue (BR) from Greek Al industry, using a combination of microscopic, analytical, and spectroscopic techniques. SEM-EDS indicated a homogeneous dominant "Al-Fe-Ca-Ti-Si-Na-Cr matrix", appearing at the microscale. The...

Substorms generally inject tens to hundreds of keV electrons, but intense substorm electric fields have been shown to inject MeV electrons as well. An intriguing question is whether such MeVelectron injections can populate the outer radiation belt. Here we...

SENSORIMOTOR DEVELOPMENT IN COCAINE-EXPOSED INFANTS.

The prolactin, cortisol and growth hormone (GH) responses to intravenous administration of 25 mg clomipramine (CMI) were studied in young male psychotic patients who had never received neuroleptics and suffered from schizophrenia (13 patients), delusional disorder (three patients) or...

The prognostic value of electroencephalography in epilepsy: a long-term follow-up study.

Neurology international

Gatzonis S, Triantafyllou N, Kateri M, Siatouni A, Angelopoulos E, Kimiskidis VK.
PMID: 21577332
Neurol Int. 2010 Nov 26;2(2):e18. doi: 10.4081/ni.2010.e18.

Predicting the evolution of epilepsy is of obvious importance for patients and their families. Value of electroencephalography (EEG) is extensively used in the diagnosis of epilepsy yet its role as a prognostication method remains unclear. The aim of the...

Artifacts in the assay of maize leaf phosphoenolpyruvate carboxylase activity due to its instability.

Photosynthesis research

Angelopoulos K, Stamatakis K, Manetas Y, Gavalas NA.
PMID: 24425242
Photosynth Res. 1988 Nov;18(3):317-25. doi: 10.1007/BF00034836.

When the assay of maize leaf phosphoenolpyruvate carboxylase (EC 4.1.1.31) activity is started with phosphoenolpyruvate, much lower reaction rates are obtained as compared to the enzyme-initiated reaction. The difference is due to the lability of the dilute enzyme in...
