We report a study of the quantum Hall effect and Shubnikov-dc Haas oscillations in semimctallic type II heterostructures of the strained layer system InAs/Ga1−xInxSb which are almost intrinsic. In high magnetic fields up to 50 T, ρxy has large pea

Ultra-high magnetic field (> 150 T) cyclotron resonance has been performed on type II InAs/Ga(In)Sb superlattices. The electron density data reveals a dramatic depopulation at a critical magnetic field corresponding to the uncrossing of the lowest el

Cyclotron resonance of the 2-Dimensional Electron System in GaAs/Ga 0.66 Al 0.34 As heterojunctions has been studied in very high (∼ 90 T) magnetic fields. The resonance is found to split into two components due to the energy dependence of the elec

We examined the involvement of sphingosine kinase-1 (SphK1), which governs the ceramide/sphingosine-1-phosphate balance, in susceptibility to imatinib of either sensitive or resistant chronic myeloid leukemia cells. Imatinib-sensitive LAMA84-s displa

Although imatinib mesylate has revolutionized the treatment of chronic myeloid leukaemia (CML), resistance to the drug, manifesting as relapse after an initial response or persistence of disease, remains a therapeutic challenge. In order to overcome

Monotherapy of chronic myeloid leukemia (CML) with imatinib mesylate has been cast into shadow by the evolution of clinical resistance during therapy. Resistance to imatinib can arise by multiple mechanisms including amplification or mutation of Bcr-

Measurement of the arterial partial pressure of oxygen (PaO2 ) while breathing air is an informative investigation in patients with hypoxaemia due to chronic respiratory disease, but there are a lack of published data on the time needed for blood oxy

Holes pushed into the surface of laboratory grade CaCO3 powder reproduced visible and measurable luminescence similar to that seen and measured in coral skeletons. Heating such powder to 450 °C for 2 h did not destroy the luminescence although it di

In most survival studies in NIDDM, microalbuminuria (urinary albumin excretion rate 20-200 microg/min) predicts early mortality; in cross-sectional studies, it is associated with coronary heart disease (CHD) morbidity. It is unclear, however, whether
