Shortened pull-string simplifies office-based ureteral stent removal.

A disadvantage of stent use after ureteroscopy is the need to remove the stent cystoscopically. We describe a modification that avoids the discomfort of a transurethral suture and allows easy cystoscopic extraction. This modification may also facilitate repositioning or removal of a migrated stent.

Axillary string phlebitis in pregnancy: a variant of Mondor's disease.

A 28-year-old pregnant woman had acute superficial thrombophlebitis in the right axilla. Aside from pregnancy, there were no risk factors for hypercoagulability. This case is presented as a variant of Mondor's disease. The pendulous breasts associated with her pregnancy and strenuous lifting may have predisposed the patient to the disease.

Is the optimal viewing position in reading influenced by familiarity of the letter string?

An optimal viewing position (OVP) for word recognition has been proposed by several authors. The location of this position would be located at the center of the word or just left of it. Several hypotheses ranging from perceptual to hemispheric factors have been proposed to explain this phenomenon. In the experiment presented here, the effect of the nature of the stimulus was tested: word, pseudo-word, or nonword on the existence and location of this position. Little research has investigated this issue. Five-letter words, pseudo-words, and non-words were presented, with the subject fixating initially on one of the five possible letter positions. The number of letters correctly identified and reading performance were recorded for each stimulus. Results show that an initial fixation on the third letter entails better letter identification for all kinds of stimuli. However, in terms of reading, only word reading benefit from a fixation on the third letter. These results are discussed in relation to the different hypotheses of OVP in reading. These are (1) hemispheric specialization, (2) reading habits, and (3) lexical constraints.

Membrane cytoskeleton: PIP(2) pulls the strings.

A recent application of optical tweezers has shown that plasma membrane phosphatidylinositol 4,5-bisphosphate (PIP(2)) levels control adhesion of the membrane bilayer to the underlying cytoskeleton, by regulated direct binding of PIP(2) to cytoskeletal proteins and/or indirect effects on cytoskeleton structure.

Molecular motors: Kinesin's string variable.

A recent model suggests that the walking action of kinesin is due to a 13 residue 'fundamental engine' called the neck linker domain, which cyclically zips and unzips to the main part of the heads. New experiments confirm one prediction of the model: that crosslinking the neck linker to the head should block motility.
