Developmental changes in the repertoire of activating Ly-49 family members have not been examined previously. In the present study, we have examined the expression and function of the activating Ly-49s (D and H) from birth through 8 weeks of age. We demonstrate that 1) activating Ly-49s are expressed early, 2) their expression intensity is not different from adult NK cells, and 3) activating re...

The dermatoglyphs of 28 Japanese with Klinefelter's syndrome [24 XXY; 2 XXYY; 1 XXXY; 1 XXXXY] were compared with 544 male and 129 female controls. These patients showed high frequencies of fingertip arches pattern, right third interdigital loops, right hypothenar patterns (Lr) and line C terminating 0 in the right hand. The mean summed a-b ridge count of Klinefelter's syndrome patients was si...

In the title compound, [Fe(C(5)H(5))(C(15)H(16)NO)], the two cyclo-penta-dienyl (Cp) rings are nearly parallel to each other, forming a dihedral angle of 3.7 (1)°, and adopt a staggered conformation. The amide group is almost perpendicular to the plane of the substituted Cp ring, with a C-N-C-C torsion angle of 101.3 (2)°, and the N and O atoms in the ethanoyl group are coplanar, with a C-N-C-O...

In the crystal structure of the title compound, [Fe(C(5)H(5))(C(21)H(22)OP)], the cyclo-penta-dienyl (Cp) rings are almost parallel and are essentially eclipsed. The absolute configuration was determined as S for the planar and R for the central chirality.

The crystal structure of [3]ferrocenophan-1-one, [Fe(C(13)H(12)O)], has been redetermined at 150 K. The tethered cyclo-penta-dienyl (Cp) rings are tilted by 9.39 (18)° and assume an eclipsed conformation. The 1-oxopropane-1,3-diyl bridge has a pseudo-envelope conformation with the C=O group deviating by as much as 22.5 (2)° from coplanarity with its attached Cp ring.
