A novel LKB1 isoform enhances AMPK metabolic activity and displays oncogenic properties
The LKB1 tumor suppressor gene encodes a master kinase that coordinates the regulation of energetic metabolism and cell polarity. We now report the identification of a novel isoform of LKB1 (named ΔN-LKB1) that i...

MGMT promoter methylation and correlation with protein expression in primary central nervous system lymphoma
The O 6-methylguanine-DNA-methyltransferase (MGMT) gene encodes for a DNA repairing enzyme of which silencing by promoter methylation is involved in brain tumorigenesis. MGMT promoter methylation ...

Cutoff behaviour of graded-index slab waveguides
The cutoff behaviour of graded-index planar waveguides is analysed in terms of the normalized waveguide parameters by using the multilayer technique and the WKB approach. The results show a very high degree of...

Non reciprocal single mode conversion in multilayer magnetooptical waveguides
Multilayer structures are of great interest in the fabrication of single mode devices for Integrated Optics. this work it is shown that a multilayer structure allows not only single-mode behaviour but it enhac...

Influence of Phase Separation on the Thermal Conductivity of Potassium Borosilicate Glasses Between 1 K and 10 K
Phase separation has long been recognized in glasses and often develops as a result of thermal treatment (1). Since Kapitza’s first report, thermal resistance has also been observed in boundaries between diffe...
