OBJECTIVE: To investigate the expression of N-cadherin in bone marrow leukemic cells derived from acute leukemia patients and its clinical significances. METHODS: A total of 113 patients with acute leukemia were enrolled in this study. Flow cytometry was employed to detect the expression of N-Cadherin in bone marrow leukemic cells from acute leukemia patients and the relationships between the N-cadherin expression and the clinical characteristics of patients with acute leukemia were analyzed...

A photo-responsive liposome was developed by loading 7-acetoxy coumarin (ATC) in egg phosphatidylcholine (EPC) liposome. ATC was derivetized from 7-hydroxy coumarin using sodium acetate. The ATC-loaded liposomes were prepared by suspending the dry mixture film of ATC/EPC in distilled water and sonicating the suspension. When the ATC to EPC ratio was less than 1:8, homogeneous liposomal suspensions were obtained without any precipitate. On 1H NMR spectra, the unsaturated chains of liposomal EPCs were somewhat deteriorated by a subsequent irradiation, the irradiation of lambda = 365 nm and then the irradiation of lambda = 254 nm...

Fullerenes are chemical structures made of carbon atoms. The stable form is molecule composed of 60 carbon atoms arranged in a soccer ball-shaped structure. With respect to its electron donor and acceptor capability and photochemical behavior fullerenes can be effective antioxidants and radical scavengers or prooxidants and photosensitizers. These properties of fullerenes have paid attention on their possible biological applications. Results of previous studies point to the great dependance of fullerenes activity upon quality, quantity and geometry of substituents in fullerene derivatives...

Forty-five samples from 1988-1995 of naturally contaminated grain, barley, wheat and oats, three samples of mixed feed, and 16 samples of grain artificially inoculated with Fusarium culmorum during the flowering stage were analysed for deoxynivalenol (DON), 3-acetyldeoxynivalenol (3-acetyl-DON), culmorin and hydroxy-culmorins. These compounds are secondary metabolites produced by the fungal species F. culmorum and F. graminearum. Acetonitrile-water extract of the samples was purified on a Mycosep #225 column, derivetized using penta-fluoropropionic anhydride (PFPA) and analysed by gas chromatography-mass spectrometry (GC-MS)...

The neutral lipids of nine species of methanogenic bacteria including five methanobacilli, two methanococci, a methanospirillum, one methanosarcina as well as two thermoacidophilic bacteria, Thermoplasma and Sulfolobus, were analyzed. The major components were C30, C25 and/or C20 acylic isoprenoid hydrocarbons with a continuous range of hydroisoprenoid homologues. The range of acyclic isoprenoids detected were from C14 to C30. Apart from Methanosarcina barkeri, squalene and/or hydrosqualene derivetives were the predominant components in all species studied...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
