    • Skin sealants are usually applied over skin preps to seal the skin and hold any remaining bacteria in place prior to surgical incisions. This sealant is generally left on the skin after surgery. A skin coating is provided that has an indicator that gives a visible color change upon contact with microbes or microbial by-products and so provides an early warning of infection. The coating is a curable coating composition that may also be used without skin preps and may be used to protect other disruptions in the skin like wounds, bruises, abrasions, burns, acne, blisters, bites, stings, punctures and cuts. It may also be used to close wounds or provide an additional barrier to other parts of the skin, such as the nails and mucosa.
    • 皮肤密封剂通常用于皮肤制服上以密封皮肤,并且在手术切口之前将任何残留的细菌保持在适当位置。 这种密封剂通常在手术后留在皮肤上。 提供皮肤涂层,其具有指示剂,其在与微生物或微生物副产物接触时产生可见的颜色变化,因此提供感染的早期预警。 该涂层是可固化的涂料组合物,其也可以不使用皮肤制剂使用,并且可以用于保护皮肤中的其它中断,例如伤口,瘀伤,擦伤,烧伤,痤疮,水疱,叮咬,叮咬,刺穿和切口。 它还可以用于闭合伤口或提供对皮肤其他部分(例如指甲和粘膜)的额外屏障。

    • A method for semi-quantitatively or quantitatively detecting the presence of a microbe in a sample is provided. The method utilizes a test dye that undergoes a detectable color change in the presence of one or more microbes. For example, in one embodiment, the test dye is a solvatochromic dye (e.g., Reichardt's dye) that responds to differences in polarity between microbe components (e.g., cell membrane, cytoplasm, etc.) and the environment outside the cell. Alternatively, other mechanisms may be wholly or partially responsible for the interaction between the dye and the microbe, such as acid-base reactions, redox reactions, and so forth. Regardless, the color of the test dye may be compared to the color of a control dye, wherein the color of the control dye corresponds to a known microbe concentration.
    • 提供了一种半定量或定量检测样品中微生物存在的方法。 该方法利用在一种或多种微生物存在下经历可检测的颜色变化的测试染料。 例如,在一个实施方案中,测试染料是响应于微生物组分(例如细胞膜,细胞质等)与细胞外的环境的极性差异的溶剂化色素染料(例如,Reichardt's染料)。 或者,其它机理可以完全或部分地负责染料和微生物之间的相互作用,例如酸碱反应,氧化还原反应等。 无论如何,可以将测试染料的颜色与对照染料的颜色进行比较,其中对照染料的颜色对应于已知的微生物浓度。

    • A method and system for rapidly detecting Candida on the skin of a host, such as an infant with diaper rash, is provided. The method includes contacting a dermal sample with a colorant that exhibits a certain spectral response (e.g., color change) in the presence of Candida. For example, the colorant may change from a first color to a second color, from colorless to a color, or from a color to colorless. The colorant is typically capable of differentiating between Candida (e.g., Candida albicans) and other microorganisms commonly associated with diaper rash, such as S. aureus and E. coli. Thus, when a dermal sample is placed into contact with the colorant, the color change may simply be observed to determine whether the infection is caused by Candida. If the color change occurs to a certain extent (e.g., from yellow to bright red), it may be determined that the test sample contains Candida. Likewise, if a color change occurs to a lesser extent (e.g., from yellow to faint orange) or not at all, it may be determined that the dermal sample contains other microorganisms (e.g., S. aureus or E. coli), no infection is present, or that the infection is simply due to other causes. Regardless, it will become readily apparent whether or not treatment for Candida is needed.
    • 提供了用于快速检测宿主皮肤上的假丝酵母的方法和系统,例如具有尿布疹的婴儿。 该方法包括使真皮样品与在假丝酵母存在下显示特定光谱响应(例如颜色变化)的着色剂接触。 例如,着色剂可以从第一颜色变为第二颜色,从无色到颜色,或从颜色变为无色。 着色剂通常能够区分假丝酵母(例如白色念珠菌)和通常与尿布疹相关的其它微生物,例如金黄色葡萄球菌和大肠杆菌。 因此,当真皮样品与着色剂接触时,可以简单地观察颜色变化以确定感染是否由念珠菌引起。 如果颜色变化发生一定程度(例如,从黄色到鲜红色),则可以确定测试样品含有念珠菌。 同样地,如果在较小程度上发生颜色变化(例如,从黄色到微弱橙色),或根本不发生变色,则可以确定真皮样品含有其他微生物(例如金黄色葡萄球菌或大肠杆菌),无感染 存在,或感染仅仅是由于其他原因。 无论是否需要对念珠菌的治疗,将变得显而易见。

    • A tablet that is capable of reducing odor when added to a liquid is provided. The deodorizing tablet may be used in a wide variety of applications in which odor control is desired, such as in toilets, water treatment/sewage systems, well water, bedpans, and so forth. In addition to providing odor control, the tablet is generally soluble in the liquid so that its components are better able to contact malodorous compounds contained within the liquid. In this regard, the present inventors have discovered that certain quinone compounds are both odor inhibiting and also soluble in liquids (e.g., urine), and thus particularly useful in forming the deodorizing tablet of the present invention.
    • 提供了当添加到液体中时能够减少气味的片剂。 除臭片剂可用于需要气味控制的各种应用中,例如在厕所,水处理/污水系统,井水,卧床等中。 除了提供气味控制之外,片剂通常可溶于液体,使得其组分更好地接触包含在液体中的恶臭化合物。 在这方面,本发明人已经发现某些醌化合物既气味抑制又可溶于液体(例如尿液),因此特别可用于形成本发明的除臭片剂。
