Novel materials based on DNA-CTMA and lanthanide (Ce(3+) , Pr(3+) ).

New, deoxyribonucleic acid (DNA) based compounds, functionalized with hexadecyltrimethylammonium chloride (CTMA) and lanthanide hydroxide nanoparticles were synthesized. The spectral measurements suggest that between the DNA-CTMA complex and the lanthanide (III) ions a chemical interaction takes place. The obtained materials exhibit an improved fluorescence efficiency, showing a potential interest for application in photonics, and more particularly, in light emitting devices. © 2016 Wiley Periodicals, Inc.

[Malignant non-Hodgkin conjunctival-orbital lymphoma in the years 1990-2005 at the Ophthalmology Clinic of Oradea]. / Limfoamele maligne non-hodgkiniene conjunctivo-orbitare internate în perioada 1990-2005 în clinica de oftalmologie oradea.

Non-Hodgkin conjunctival-orbital Malignant Lymphoma, there are rare tumors, difficult to be diagnosed. We've made a clinical and paraclinical retrospective study, along 15 years (1990-2005) period of time, analyzing from the point of view, clinical features and anatomo-pathological results, each of the 11 cases that we found.
