BACKGROUND In myeloid blasts, the expression and release of the multifunctional chemokine IL-8 could be expected to be differentiation-associated. METHODS We investigated the profile of interleukin-8 (IL-8) expression and release by leukemic cells obtained at diagnosis from 42 untreated adult patients with acute myeloid leukemia of various FAB subtypes (2 M0, 7 M1, 6 M2, 6 M3, 10 M4 and 11 M5...

The biotransformation of taxol by human liver was investigated in vitro with microsomes isolated from adult and developing human tissues. In vitro, no metabolism was detected with kidney microsomes, whereas two metabolites were generated by liver microsomes. The most prominent metabolite, termed M5, corresponded to an hydroxylation at the C6 position on the taxane ring, while the other metaboli...

CONTEXT Flow cytometric immunophenotyping is a useful ancillary tool in the diagnosis and subclassification of acute myeloid leukemias (AMLs). A recent study concluded that CD64 is sensitive and specific for distinguishing AMLs with a monocytic component (ie, AML M4 and AML M5) from other AML subtypes. However, in that study, the intensity of CD64 was not well defined and the number of non-M4/n...

The primary alcohol/aldehyde dehydrogenase (coded by the aad gene) is responsible for butanol formation in Clostridium acetobutylicum. We complemented the non-sporulating, non-solvent-producing C. acetobutylicum M5 strain (which has lost the pSOL1 megaplasmid containing aad and the acetone-formation genes) with aad expressed from the phosphotransbutyrylase promoter and restored butanol producti...

3-n-Butylphthalide (NBP) is a cardiovascular drug currently used for the treatment of cerebral ischemia. The present study aims to investigate the metabolism, pharmacokinetics, and excretion of NBP in humans and identify the enzymes responsible for the formation of major metabolites. NBP underwent extensive metabolism after an oral administration of 200 mg NBP and 23 metabolites were identified...

The French-American and British (FAB) classification of 62 consecutive cases of acute myeloid leukemia was undertaken. AML-M2 was the commonest FAB type (32.26%), followed by M1 and M4 (22.58% each), M5 (8.6%) and M6 and M7 (1.61% each), respectively. One of the patients was diagnosed as AML-MO (not a FAB type). The mean age of M1, M2, M3 and M5 cases was between 25 and 29 years, whereas in M4 ...

M5-branes wrapping a holomorphic curve in a Calabi-Yau manifold can be used to construct four-dimensional N = 1 gauge theories. In this paper we will consider M5-brane configurations corresponding to N = 2 theories broken to N = 1 by a superpotential for the adjoint scalar field. These M5-brane configurations can be obtained by lifting suitable intersecting brane configurations in type IIA, or ...
