A 67 year-old male with poorly controlled diabetes and persistent leukocytosis despite appropriate antibiotic treatment for pneumonia underwent computer-tomography (CT) scanning to evaluate for additional sources of infection. He was noted to have a 3.5 centimeter rim enhancing fluid collection at the level of his bulbar urethra (Figure-1, Panel A, B, C). Upon questioning, the patient recalled ...
A retro-inverso peptide is made up of d-amino acids in a reversed sequence and, when extended, assumes a side chain topology similar to that of its parent molecule but with inverted amide peptide bonds. Despite their limited success as antigenic mimicry, retro-inverso isomers generally fail to emulate the protein-binding activities of their parent peptides of an alpha-helical nature. In studyin...
Retro-auricular cellulitis associated with otitis externa is now the great mimicker of mastoiditis. It may be the most common cause of this specific cellulitis/auricular protrusion when it is associated with otitis externa. This column presents six cases of children who presented with peri-auricular redness, four of whom had protuberant ear and retro-auricular cellulitis.
A girl developed progressive weakness of bulbar and ocular muscles starting before the age of two years. Electromyography revealed a widespread subclinical myopathy. An intercostal muscle biopsy showed complex abnormalities including occasional neurofilamentous accumulations and honeycomb-like membranous material in terminal axons. Endplates were small and some secondary synaptic clefts were ab...
[reaction: see text] The scope and generality of a new reaction of indoles with MTAD is discussed. In most cases the ene-type reaction proceeds within seconds or minutes at 0 degrees C to provide the urazole adducts in high yield. This reaction provides the first method for protecting the indole 2,3-double bond since the urazole adducts can be reconverted to the starting indole (retro-ene) simp...
A novel pyrrolidine-based chiral phosphoproline is an effective bifunctional organocatalyst for the asymmetric Michael addition of ketones to nitroolefins giving high levels of diastereo- and enantio-selectivities (up to > 99 : 1 dr and 96% ee). anti-SR Transition state has the lowest barrier which controls the stereoselectivity, in agreement with experimental results.
