Disclosed herein are example embodiments of a transformative sensor apparatus that is capable of detecting and quantifying the presence of a substance of interest such as a specified bacteria within a sample via changes in impedance exhibited by a detection electrode array. In an example embodiment, sensitivity is improved by including a focusing electrode array in a rampdown channel to focus a concentration of the substance of interest into a detection region. The focusing electrodes include an opposing pair of electrodes in a rampdown orientation. The focusing electrode may also include tilted thin film finger electrodes extending from the rampdown electrodes. In another example embodiment, trapping electrodes are positioned to trap a concentration of the substance of interest onto the detection electrode array.

The present invention includes a novel method and system for identification of microorganisms in samples that proteins and other biological material from non-microorganism sources (e.g., proteins of mammalian origin) that can interfere with identification of the microorganisms. The methods and systems described herein include use of a single-use chromatography medium to purify intact proteins prior to mass spectrometry analysis. The chromatography medium and the methods described herein can rapidly and efficiently remove of a substantial portion of interfering biological material (e.g., mammalian proteins) from a crude cell lysate while preserving high signal strength and removing enough of the interfering protein(s) to allow for identification of the microorganism(s) by mass spectrometry analysis.

The present invention relates to a kit for predicting or diagnosing the degree of risk of disease, a method for providing information for predicting or diagnosing the degree of risk of disease, a method for screening a therapeutic agent of disease, and a pharmaceutical composition for prevention or treatment of disease, for nonalcoholic fatty liver disease. Specifically, through the kit for predicting or diagnosing of the present invention, the degree of risk of nonalcoholic fatty liver disease can be effectively predicted or diagnosed, and in particular, the predictive value and significance of information provision in non-obese subjects are excellent. Therefore, by providing effective information on nonalcoholic fatty liver disease through this, it can be effectively used to prevent or treat the corresponding disease. In addition, the pharmaceutical composition for prevention or treatment of the present invention may be effectively used for treatment of nonalcoholic fatty liver disease.

The present invention relates to a composition for preventing, alleviating or treating liver injury, for example, nonalcoholic fatty liver, and more specifically, it relates to a composition for preventing or treating liver injury comprising a Ruminococcus spp. strain.

Coliform detection is provided via the alpha (“α”) form of enzyme substrates. The α form can be mixed with a dry growth media suitable for target Coliforms and then applied as needed to a test card format, or then mixed with water and sterilized for use a broth applied to a membrane filter detection device, for example.

Every year, approximately 94 million cases of Salmonella gastroenteritis, with 155000 deaths, are reported each year and 85% of them reported to be food-borne. Investigation of the foods whether they are clean for Salmonella and sensitivity, easy applicability, absence of false positivity and negativity and the speed are the features sought in the analysis method for this investigation. It is not desirable for analysis to detect the presence of dead bacteria in food. Although the final product does not contain microbiologically harmful live bacteria during the food process, the detection of dead bacteria transmitted before the process causes the food product to be unfairly diagnosed as harmful. To prevent this situation, the analysis kits depending on molecular methods, increase their microorganism detection levels up to to 10.sup.4 while reducing their sensitivity. Since the molecular methods cannot discriminate dead and live organisms, a confirmation test is required to prove that the positive result of the analysis belongs to the live bacteria in the food, which results in additional cost and time loss. In the same way, it is necessary to verify whether the colonies that grow in the gold standard culture method, belong to Salmonella bacteria. In the developed system; 10.sup.5 dead bacterial DNA is eliminated in the food to prevent false positive results and the minimum detection limit is 10 bacteria. Also, in developed system, 4 primers specific to 6 regions of DNA are used. Therefore, the specificity of the method is very high (99.9%) and no verification test is needed. Since PCR systems require a device with complex temperature control units, they can make analysis in a laboratory-dependent manner. In the proposed system, DNA is amplified at constant temperature; no temperature cycle is required, therefore no complex instrument and laboratory infrastructure are required. All the procedures can be easily performed outside the laboratory on a portable mini-heater where pre-enrichment, DNA isolation from the sample and PCR steps are performed. For molecular analyses, the device is required to display the result of imaging or analysis. In the developed method, DNAs amplified by the loop-mediated isothermal DNA amplification method, are hybridized and combined with the labeled probe and then can be read by lateral flow method with the naked eye. As the results are visible by eye, no additional device is required. The classical culture method is accepted as the gold standard, but the duration of analysis is 7 days for positive samples, 3 days with verification test, for the molecular methods, and 5.5 hours including pre-enrichment time
