Acute cerebral infarction in a patient with nodular glomerulopathy—Atypical features and differential diagnosis

AbstractNodular glomerulopathy is a pattern of glomerular injury observed under light microscopy that could result from several diseases presented as nephrotic syndrome clinically. Compared with venous thrombosis, cerebral infarction resulting from arterial thrombosis is relatively rare in these patients. We report an interesting case of severe nephrotic syndrome complicated with acute cerebral infarction, and renal biopsy revealed nodular glomerulopathy under light microscopy. Immunofluorescent staining was positive for λ light chain (predominant) and κ light chain, mainly in mesangial areas, and electron microscopic study showed massive amorphous acellular deposits also in mesangial areas with some local extension to subendothelial space. Congo red stain gave negative results under polarized light. The case was concluded as an atypical presentation of light chain deposition disease both pathologically and clinically

Chlorofullerenes featuring triple sequentially fused pentagons

Xiamen Univ, Coll Chem & Chem Engn, Dept Chem, Xiamen 361005, Peoples R China 电子邮件地址: [email protected], [email protected] triple sequentially fused pentagons (TSFP) motif is one of the basic subunits that could be used for constructing fullerenes, but it violates the isolated pentagon rule (IPR) and has not been found in carbon cages to date. The properties of TSFP-incorporating fullerenes are thus poorly explored both theoretically and experimentally. Reported herein are four chlorinated derivatives of three different fullerene cages, all with the TSFP motif. X-ray crystallographic analyses indicate that the molecular strain inherent to the pentagon adjacency of a TSFP is significantly relieved upon exohedral chlorination, leaving one of the four pentagon fusion sites unsaturated and rendering the present derivatives chiral. This unique reactivity, in stark contrast to that of previously reported non-IPR fullerenes containing double fused pentagons or triple directly fused pentagons, can be rationalized by density functional theory calculations, and are expected to stimulate further studies of these new members of the fullerene family, both theoretically and experimentally.NNSF of China 20525103,20531050,20721001,20423002 20673088 973 Program 2007CB81530
