The disclosed stent is formed of an elongate, flexible duct having a very thin wall and a preformed diameter, length, and shape. The stent is constructed of a woven tubular structure of multiple strands or elements. The woven tubular structure is thermally set to a predetermined diameter and length, so that the "at rest" or natural condition of the tubular structure is predictable. A retention or holding member can be formed at one or both of the ends of the stent. This retention member can be reduced in diameter for insertion into the body passage. The woven tubular structure provides a path for fluids to flow in and around the stent, while a patent lumen is being developed. The woven tubular structure allows the stent to be extended or stretched over a guidewire or other noncompressive member, to thereby reduce the diameter of the stent for insertion of the stent into a body passage.

Elucidating the function of proteins in mammalian cells is particularly challenging due to the inherent complexity of these systems. Methods to study protein function in living cells ideally perturb the activity of only the protein of interest but otherwise maintain the natural state of the host cell or organism. Ligand-dependent inteins offer single-protein specificity and other desirable features as an approach to control protein function in cells post-translationally. Some aspects of this invention provide second-generation ligand-dependent inteins that splice to substantially higher yields and with faster kinetics in the presence of the cell-permeable small molecule 4-HT, especially at 37° C., while exhibiting comparable or improved low levels of background splicing in the absence of 4-HT, as compared to the parental inteins. These improvements were observed in four protein contexts tested in mammalian cells at 37° C., as well as in yeast cells assayed at 30° C. or 37° C. The newly evolved inteins described herein are therefore promising tools as conditional modulators of protein structure and function in yeast and mammalian cells.

Automatic detection and switching between computer-enabled input modes is provided. An automatic switching input mode may be selected that allows input modes to be automatically switched from one mode to another based on user behavior. If a user's computer system is in selection mode (keyboard or mousing device), the user may enter and manipulate data via mouse movement or keyboard selection. If the user moves an electronic pen to the user's computer display screen, her computer system automatically switches to pen input mode without the requirement that the user manually switch to pen mode. Subsequently, if the user moves her mousing device or selects a key on her keyboard, her system automatically switches back to selection mode. Additionally, one input mode may be readily latched for operation as a different input mode. For example, a user may latch a pen input mode for operation as a mouse input mode. Conversely, a mouse input mode may be latched for operation as a pen input mode. Each input mode may be easily switched back to its natural state based on user behavior.
