摘要： A rapid, non-invasive breath-test method and device for diagnosing the presence or absence of H. pylori in a subject without administration of isotopic tracers is described. The device consists of a highly sensitive colorimetric ammonia sensor placed in contact with sampled subject breath. The sensor is measured using appropriate reflection spectroscopy instrumentation. The breath-test method consists of measuring a basal ammonia level with the device, administering non-isotopic urea and continuing measurement of the ammonia content in a plurality of consecutive breaths. Diagnostic differences in breath ammonia are identified between H. pylori infected and uninfected individuals.

摘要： A method and device is provided for collecting filterable material to perform assays on a filtration apparatus by applying negative-pressure to the inlet chamber of the filtration apparatus which is independent of negative or positive pressure applied to its fluid path. The negative-pressure applied to the inlet chamber serves to actively aspirate fluid and promote flow into the inlet chamber via the fluid pathway. The negative-pressure applied to the inlet chamber facilitates the use of either negative or positive-pressure based fluid-filtration approaches. Use of the invention improves the functionality and scope of applications that can be performed with enclosed filtration apparatuses.
摘要翻译：提供了一种方法和装置，用于收集可过滤材料，以通过向过滤装置的入口室施加负压而对过滤装置进行测定，该过滤装置独立于施加到其流体路径的负压或正压。施加到入口室的负压用于主动地吸入流体并促进经由流体通路流入入口室。施加到入口室的负压有利于使用负压或基于正压的流体过滤方法。本发明的使用改进了可以用封闭的过滤装置执行的应用的功能和范围。

摘要： A method and apparatus for detecting dental plaque or calculus deposits on a tooth site using a pulse of broad band light to illuminate a tooth site thereby exciting the deposit to luminescence. A time-related characteristic of the luminescence, such as its decay rate, is then analyzed to detect the presence of plaque or calculus at the tooth site. The excitation radiation preferably encompasses a range of wavelengths between about 375 nm to 575 nm, and the time-related characteristic of the luminescence that is analyzed preferably has a wavelength above about 600 nm.
