In this paper we introduce the concept of Wiener–Luxemburg amalgam spaces which are a modification more classical Wiener intended to address some shortcomings latter face in context rearrangement-invariant Banach function spaces. We and study their properties, including (but not limited to) normability, embeddings between them associate also amalgams quasi-Banach necessary generalisation then a...
Inexpensive protic ionic liquids, synthesized from di- or triamines and excess sulfuric acid, were used as solvents catalysts for the Beckmann rearrangement. The use of liquids in place oleum acid allowed base neutralization step, which is required conventional rearrangement, to be entirely avoided, thereby dramatically improving atom economy. Using a biphasic water/organic solvent extraction s...
T cell rearranging gene gamma (TRG gamma) and T cell antigen receptor beta (TCR beta) chain gene rearrangement and transcription were studied in a series of patients with B-lineage acute lymphoblastic leukemia (ALL), in which the Ig H chain genes are rearranged and the surface phenotype reproduces the stages of normal pre-B maturation. For comparison, polyclonal T cells from peripheral blood of...
INTRODUCTION Accurate determination of ALK rearrangement is important in lung cancer patients, especially in determining their eligibility for crizotinib therapy. Fluorescence in situ hybridization (FISH) has been regarded as the gold standard method for detecting ALK rearrangement. However, FISH requires a fluorescence microscope, and the signals are labile and rapidly fade over time. This stu...
Here we describe a full structural elucidation of the diethyl (2-(4-phenyl-1H-1,2,3-triazol-1-yl)benzyl) phosphate. This compound is common by-product present in synthetic protocols to access α-hydroxy phosphonate compounds through Phospha-Brook rearrangement. Thus, complete NMR characterization this rearrangement was performed by 1H, 13C{1H}, 31P{1H}, COSY, HSQC, and HMBC experiments. Addition...
