Abstract:
Methods, kits, and apparatus for locating, labelling, and accessing breast ducts are described. An orifice to one or more ductal networks is marked to enhance visibility. In a first embodiment, the orifice is labelled using a specific binding substance, typically an antibody, specific for a tissue marker present on the orifice. Exemplary tissue markers include those present on the ductal epithelium, such as cytokeratins, including cytokeratin 8 and cytokeratin 18; cadhedrins, such as E cadhedrin; and epithelial membrane antigens. In a second embodiment, a dye is injected into the base of the nipple and preferentially accumulates at at least some of the orifices. Other marking techniques are also described. Marking of the ductal orifices permits reliable identification and access to each of the multiple ductal networks which may be present in an individual breast.
Abstract:
Disclosed are methods for detecting demineralization of a surface of a tooth, comprising a) contacting the tooth of a subject with an orally acceptable, binding composition comprising a binding agent that binds to a demineralized surface of the tooth; b) removing unbound binding compound; c) contacting the tooth with an orally acceptable, detector composition comprising a probe compound that reacts with the binding agent to form a visually detectable reaction product; and d) detecting formation of the reaction product as an indication of the presence or extent of surface demineralization of the tooth. Systems, kits, and compositions for practicing the methods are also provided.
Abstract:
The present invention provides a novel liquid composition in the form of an emulsion or microemulsion for rectal administration comprising at least one dye, at least one emulsifier, and at least one physiologically acceptable excipient, and its use in a diagnostic endoscopic procedure of sigmoid colon and/or rectum. Preferably, said diagnostic endoscopic procedure of sigmoid colon and/or rectum is an anoscopy, a proctoscopy, a rectoscopy and/or a sigmoidoscopy.
Abstract:
Described herein are systems and corresponding methods to place and further monitor an implanted medical device. The implanted device includes a fluorescent material that is disposed on a portion of a tip of the device. The system also includes a skin patch having one or more infrared light detectors configured to detect light radiation from the fluorescent material on the implanted device located beneath a skin surface of living tissue. The system further includes an image processing module that is configured to construct an image of the implanted device and its surroundings. The processor further registers and analyzes the position of the implanted device and provides an appropriate feedback signal to a monitoring station.
Abstract:
본 발명은 암 조직에 대한 표적지향성이 향상된 특징을 가지는 항암나노입자 및 이의 제조방법에 관한 것으로서, 더욱 상세하게는 항암제, 나노입자 기저재로 혈청알부민 및 표적지향물질로 포르피린계 화합물이 비공유적으로 결합된 표적지향증폭형 항암나노입자 및 이의 제조방법에 관한 것이다. 본 발명에 따른 표적지향증폭형 항암나노입자는, 항암제, 기저재 혈청알부민, 표적지향물질 포르피린 이 3가지 성분들이 비공유결합적으로 구성되기 때문에, 항암나노입자에서 흔히 나타나는 독성 부작용, 항암제 약효 감소와 표적지향성 감소를 막을 수 있고, 나노입자가 더욱 안정화되고, 표적지향물질인 포르핀의 화학구조가 전혀 변형되지 않아 포르피린 고유기능인 활성산소 형성기능이 살아있어 전자기파 조사시 암 표적지향성이 증폭되는 효과를 가진다. 이상의 효과들이 복합적으로 작용하여 본 발명의 표적지향증폭형 나노입자는 항암제의 암 전달율/표적화율을 극대화시켜, 초기는 물론 말기 암에서도 효과적인 치료를 기대할 수 있다.
