macromolecular crowding fails to fold a globular protein in cells.proteins perform their functions in cells where macromolecular solutes reach concentrations of >300 g/l and occupy >30% of the volume. the volume excluded by these macromolecules stabilizes globular proteins because the native state occupies less space than the denatured state. theory predicts that crowding can increase the ratio of folded to unfolded protein by a factor of 100, amounting to 3 kcal/mol of stabilization at room temperature. we tested the idea that volume exclusion dominates the c ...201121534566
appendicitis: when there is more than meets the eye.acute appendicitis is the most frequent emergency in gastrointestinal surgery. obstruction of the appendiceal lumen appears to be one of the most common physiologic mechanisms for the development of acute appendicitis. once obstructed, the dilatation of the lumen causes ischemia and necrosis of the wall. the most common organisms involved in appendicitis are escherichia coli, peptostreptococcus, bacillus fragilis and pseudomonas. rarely, actinomyces is involved in this process. in this case repo ...201121763232
microbiology of sinusitis.most sinus infections are viral, and only a small proportion develops a secondary bacterial infection. rhinoviruses, influenza viruses, and parainfluenza viruses are the most common causes of sinusitis. the most common bacteria isolated from pediatric and adult patients with community-acquired acute purulent sinusitis are streptococcus pneumoniae, haemophilus influenzae, moraxella catarrhalis, and streptococcus pyogenes. staphylococcus aureus and anaerobic bacteria (prevotella and porphyromonas, ...201121364226

fluorescence correlation spectroscopy of fast chain dynamics within denatured protein l.intramolecular dynamics in the denatured state of a protein are of importance for protein folding. native-like contact formation within the ensemble of denatured conformations of a protein may guide its transformation towards the native conformation. the efficiency of folding is thus dependent on the diffusion of chain fragments, which facilitates contact formation. herein we investigate intramolecular diffusion of denatured molecules of the small two-state-folding protein l with fluorescence co ...201121271633
