Dedicated to Professor Heinrich Nöth on the occasion of his 85th birthday The rare-earth fluoride borates RE4B4O11F2 (RE = Pr, Nd) were obtained in a Walkertype multianvil device from the corresponding rare-earth oxides and fluorides, and boron oxide. Pr4B4O11F2 was obtained under high-pressure/high-temperature conditions of 8.5 GPa/1150 ◦C, and Nd4B4O11F2 at 8 GPa and 1300 ◦C. The single-cryst...

Three forms of the amino terminal half (variable region) of human pathological lambda light chains of immunolglobulins were identified antigenically. By study of all completely sequenced Bence Jones proteins hitherto analyzed and a greater number of proteins subjected to automated sequence determination as well as normal light chains three distinct isotypic basic sequences were identified. The ...

La(21)Ru(9+x)In(5-x) (Pearson symbol tI140) is isotypic to the filled Y(3)Rh(2)-type structure, from which it can be derived through an ordered substitution at two sites. One of the square-prismatic sites (site symmetry ..m) is occupied by a mixture of Ru and In atoms and one of the square-antiprismatic sites (4/m..) is fully occupied by In atoms.

The crystal structures of CuTe;Br and CuTe2I have been refined on the basis of single crystal data. Both compounds crystallize monoclinically in space group P2,/c. The structures are isotypic with that of CuTe2Cl. The lattice param eters of CuTe2Br are a — 834.5(8) pm. b = 492.8(4) pm, c = 1573.3(5) pm and ß = 135.3(2)°. The unit cell dimensions of C uT eJ are a = 866.5(8) pm, b — 491.4(4) pm, ...

both zoonotic and anthroponotic cutaneous leishmaniasis (cl) caused by l. major and l. tropica, respectively, are endemic in different parts of iran. this study was performed to investigate the new changes in epidemiological pattern of cl, and to identify the species of leishmania and the strains of l. major isolated from different endemic areas of iran. seventy-two isolates from 245 samples co...

to determine the presence of anticardiolipin (acl) antibodies in patients with ischemic events, we designed a case-control study. we studied 33 patients with unstable angina, 33 male patients with myocardial infarction and 34 control subjects with no evidence of ischemic heart disease. plasma samples were assessed for igg anticardiolipin antibodies by enzyme-linked immunosorbent assay (elisa). ...

conclusions thyroid dysfunction was not higher in sle patients compared to healthy individuals. however, anti-tg antibodies were higher in sle patients. it has not yet been established that thyroid function tests should be performed routinely in sle patients. results the mean age of sle patients and controls were 32.16 ± 9.19 and 32.48 ± 9.47 years, respectively (p = 0.821). patients had signif...

despite the major advances in conventional forms of treatment (i.e. surgical techniques, radiotherapy and chemotherapy) and improved survival rates, cancer is still the second leading cause of death in developing countries. one major limitation of cytotoxic drugs and radiation in the treatment of cancer patients is their inability to discriminate between malignant and normal tissues. this in tu...
