The interactions of the cell-surface carbohydrate, Lex (Gal-& 1+4-( Fuc-a1+3)-GlcNAc) and the Lexcontaining glycosphingolipid, Lex-LacCer, and their analogues were examined by ion spray mass spectrometry. Both Lex and Lex-LacCer complexed the divalent cations, Ca2+, Mn2+, and Mg2+, to form [nLex + cation2+]2+ and [nLexLacCer + cation2+J2+ ( n = 1, 2, or 3) with greater stability observed for th...

This paper describes the evaluation of precise point positioning (PPP) using the Quasi-Zenith Satellite System (QZSS) L-band Experiment (LEX) signal. The first QZSS, the Japanese regional satellite navigation system, was launched from Japan in September 2010. QZSS transmits augmentation signals to enhance the global navigation satellite system (GNSS) positioning accuracy. One of the QZSS augmen...

[Purpose] Lower-limb deep vein thrombosis is a complication of orthopedic surgery. A leg-exercise apparatus named "LEX" was developed as a novel active-exercise apparatus for deep vein thrombosis prevention. Muscle activity was evaluated to assess the effectiveness of exercise with LEX in the prevention. [Subjects] Eight healthy volunteers participated in this study. [Methods] Muscle activities...

The quantity of tumor-associated antigens carrying type 2 chain polylactosamines with four types of fucosyl determinants, LeX (X-hapten), poly-LeX, sialyl LeX, and LeY (Y-hapten), present in sera of patients with various malignant and non-malignant disorders, as well as the qualitative chemical properties of the carrier molecules in sera, have been investigated using four monoclonal antibodies,...

Carbohydrate antigens are useful markers for the serological detection of pancreatic cancer. However, data concerning the expression of structurally well-defined carbohydrate antigens in normal and malignant pancreatic tissue is quite limited. The Lex and Leg antigens are closely related carbohydrate antigens synthesized on type 2 blood group oligosaccharide side chains of glycolipids and glyco...

The Lewis X (LeX) determinant, a trisaccharide with the carbohydrate sequence Galbeta(1-->4)[Fucalpha(1-->3)]GlcNAcbeta, is believed to be responsible for Ca2+-mediated cell-cell interactions. In partly oriented phases composed of mixtures of penta(ethyleneglycol)monododecyl ether HO(CH2CH2O)5C12H25 and n-hexanol in the presence of Ca2+ ions, the variation of the residual dipolar couplings 1DCH...

where the subscript j on the right of a graded module denotes, throughout the paper, the degree j component of that module. There are two monomial ideals canonically attached to I: the generic initial ideal Gin(I) with respect to the revlex order and the lex-segment ideal Lex(I). They play a fundamental role in the investigation of many algebraic, homological, combinatorial and geometric proper...
