    • Powered drivers and methods are disclosed, the drivers including a head housing a motor driven drive transfer assembly for operating a rotatable socket engageable at a threaded connector. A reaction unit having a fitting engagement attached to rail guides is movably maintained through the head. A biasing unit is maintained at the head and is operatively associated with the rail guides of the reaction unit to bias the fitting engagement of the reaction unit toward the rotatable socket during tightening rotation of the engaged threaded connector. A probe and switch are associated with different ones of the reaction unit and the head, and are brought into operative association at selected relative locations of the reaction unit and the head during connector rotation to cause motor cessation.

    • Oxygen levels in biological tissue or systems can be measured by the phosphorescence quenching method using phosphorescent porphyrin probes, also referred to as a dendritic oxygen probes, with controllable quenching parameters and defined biodistributions. Provided are a "next generation" of oxygen sensors with substantially improved phosphorescence emission for better imaging capabilities, ease of use, increasing the quantum efficiency (phosphorescence intensity) and extending their range of applicability including constructing a class of oxygen sensors for making measurements in organic media. In addition, provided are methods for synthesizing new porphyrin constructs in which the porphyrin is made less flexible and more planar, changing with decrease internal quenching, and thereby increasing the phosphorescence emission used for oxygen sensing. Additional methods are provided for structurally modifying the dendrimer used to encapsulate the porphyrin phosphor to provide internal quenching of singlet oxygen molecules formed during oxygen measurements.
    • 生物组织或系统中的氧水平可以通过使用磷光卟啉探针(也称为树枝状氧探针)的磷光猝灭法测量,具有可控的淬灭参数和定义的生物分布。 提供了一种“下一代”氧传感器,具有显着改善的磷光发射,以获得更好的成像能力,易于使用,增加量子效率(磷光强度)并扩展其适用范围,包括构建一类氧传感器,用于在有机 媒体。 此外,提供了合成新的卟啉构建体的方法,其中卟啉被制成较少的柔性和更平面,随着内部淬灭的减少而改变,从而增加用于氧气感测的磷光发射。 提供了另外的方法用于结构修饰用于包封卟啉磷光体的树状聚合物,以提供在氧测量期间形成的单线态氧分子的内部猝灭。
