Nanostructures of metal sulfides are conventionally prepared via chemical techniques and patterned using self-assembly. This poses a considerable amount of challenge when arbitrary shapes and sizes of nanostructures are desired to be placed at precise locations. Here we describe an alternative approach of nanoscale patterning of zinc sulfide (ZnS) directly using a spin-coatable and electron beam-sensitive zinc butylxanthate resist without the lift-off or etching step. Time-resolved electron beam damage studies using micro-Raman and micro-FTIR spectroscopies suggest that exposure to a beam of electrons lead to quick disappearance of xanthate moieties most likely via the Chugaev elimination, and further increase of electron dose results in the appearance of ZnS, thereby making the exposed resist insoluble in organic solvents...

Ocular and oral dryness are the hallmark of Sjögren's syndrome (SS). However, SS can be associated with a variety of complications, affecting organs such as the liver, kidneys, lungs, muscle, and nervous system. Renal involvement has been usually in the form of tubulointerstitial nephritis. However, glomerulonephritis is rare in primary SS. We report three clinical cases of SS with anti-neutrophil cytoplasmic antibody-mediated crescentic glomerulo-nephritis treated with prednisone and cyclophosphamide, with favorable outcome...

Various immunomodulating agents have been tried for the treatment of steroid-resistant focal segmental glomerulosclerosis (FSGS) in the native kidney. A few case series and small studies have reported mixed results with the use of Rituximab for this indication. We report on the case of a 76-year-old male with steroid-resistant FSGS successfully treated with rituximab and remained in remission at the end of six months. A review of the literature highlights the paucity of data on this subject. We conclude that rituximab is a potentially useful treatment for steroid resistant FSGS and larger controlled studies are needed to further define its role in this setting...
