background : type 1 diabetes mellitus (t1dm) is an autoimmune disease characterized by selective destruction of pancreatic beta cells.   methods: the study included 80 children, 20 of them have t1dm, 40 children were selected from first degree relatives to the same child and 20 healthy children serve as control. body mass index (bmi) was calculated, random blood glucose and glycosylated hemoglo...

Dinickel(II) silicon bis-[diphosphate(4-)], Ni(2)Si(P(2)O(7))(2), is isotypic with other phosphates of the formula M(2)Si(P(2)O(7))(2) (M = Co, Cd). All atoms except Si (site symmetry 2) are found in general positions. Ni(2)O(10) dimers formed from edge-sharing NiO(6) octa-hedra are linked by corners and O-P-O bridges, forming slabs parallel to (100), which are in turn inter-connected by O-Si-O...

A new polymorph of lutetium polyphosphate, Lu(PO(3))(3), was found to be isotypic with the trigonal form of Yb(PO(3))(3). Two of the three Lu atoms occupy special positions (Wyckoff positions 3a and 3b, site symmetry ). The atomic arrangement consists of infinite helical polyphosphate chains running along the c axis, with a repeat period of 12 PO(4) tetra-hedra, joined with LuO(6) octa-hedra.

The title mononuclear Zn(II) complex, [ZnCl(2)(C(15)H(13)N(5))(2)], is isotypic with the previously reported Hg(II) complex. The Zn(II) atom is located on a twofold rotation axis and has a distorted tetra-hedral environment of two Cl atoms and two N atoms from two heterocyclic ligands. In the crystal, complex mol-ecules are extended by inter-molecular π-π inter-actions [centroid-centroid distan...

4 cell receptor (BCR) triggering and T cell help induced initial B cell proliferation but were not sufficient to sustain prolonged survival and accumulation of B cells. Extensive proliferation, isotypic switch and differentiation to Ig-secreting cells were promoted by microbial agents acting on TLRs expressed by naïve B cells upon BCR stimulation. This finding demonstrates that humoral immune r...

The crystal structure of the binary compound tetra-calcium triarsenide, Ca4As3, was investigated by single-crystal X-ray diffraction. Ca4As3 crystallizes in the Ba4P3 structure type and is thus a homologue of isotypic Sr4As3. The unit cell contains 32 Ca(2+) cations, 16 As(3-) isolated anions and four centrosymmetric [As2](4-) dumbbells. The As atoms in each of the dumbbells are connected by a ...

Colourless single crystals of the compounds CdXO4 · 2 HgO (X = S, Se) were obtained under hydrothermal conditions (250 ◦C, 5 d), starting from stoichiometric amounts of HgO, CdSO4 ·7H2O and CdSeO4 ·2H2O, respectively. The crystal structures were determined from X-ray diffraction data sets. The CdXO4 · 2HgO compounds crystallise isotypically with two formula units in space group P1̄ (# 2) [CdSO4 ...

Li3AlAs2, Li3GaAs2 and Li3InAs2 were obtained from the elements via high temperature synthesis. Li3AlAs2 crystallize in a distorted 2 ⋅ 1 superstructure of antifluorite structure type. The orthorhombic crystal is isotypic to Li3AlP2 Li3GaP2, space group Cmce (No. 64) showing layers condensed TrAs4-tetrahedra (Tr=Al, Ga). crystallizes Li3InP2 4 type superstructure. tetragonal, I41/acd 142), 3D-n...

Transplant arteriosclerosis is characterized by inflammation and intimal thickening caused by accumulation of smooth muscle cells (SMCs) both from donor and recipient. We assessed the relationship between clinical factors and the presence of host-derived SMCs in 124 myocardial biopsies from 26 consecutive patients who received hearts from opposite-sex donors. Clinical and demographic informatio...

A graded poset structure is defined for the sets of LittlewoodRichardson (LR) tableaux that count the multiplicity of an irreducible gl(n)module in the tensor product of irreducible gl(n)-modules corresponding to rectangular partitions. This poset generalizes the cyclage poset on columnstrict tableaux defined by Lascoux and Schützenberger, and its grading function generalizes the charge statist...
