Abstract: A method and a kit for detecting mycobacterium are provided. The method includes steps of: providing a sample; providing a pair of primers, which is selected from a group consisting of a sequence having about 45% to 100% similar to SEQ ID NO. 1, a sequence having about 60% to 100% similar to SEQ ID NO. 2, a sequence complementary thereof; performing a polymerase chain reaction by using the set of primers and the sample to obtain a product; and analyzing the product to detect the presence of the mycobacterium.

Abstract: A test sheet for occult blood includes a permeable substrate layer, a test layer, and an outer layer. The permeable substrate layer and the test layer are jointed side by side or stacked from top to bottom on the outer layer. The permeable substrate layer is configured to carry biologic sample, and the test layer includes test agent. The outer layer protects the user from the biologic sample. At least one fold line is formed on the front surface of the connection of the permeable substrate layer and the test layer, or alternatively, on the front surface of the permeable substrate layer. When the test sheet is folded along the fold line, the biologic sample permeates the permeable substrate layer and reacts with the test agent. If the reaction causes color change, the biologic sample is determined to contain occult blood.

Abstract: A first-aid device for detecting myocardial infarction, including a wearable textile, a first alarm detection unit, a second detection alarm unit, and a charging first-aid unit for actively detecting and alerting to myocardial infarction, instantly supplying crucial medicine, and providing a charging function. In particular, the wearable textile put on a patient carries the first alarm detection unit actively detecting myocardial infarction, the charging first-aid unit instantly provides the user medicine to alleviate painful symptom, and at the same time, the second detection alarm unit serves as a spare part while the first alarm detection unit is charged by the charging first-aid unit. As a result, the first alarm detection unit and the second detection alarm unit are alternatively used for actively and ceaselessly detecting myocardial infarction assuring first-aid for the patient.

Abstract: A method of screening, isolating and purifying rare cells includes obtaining cell groups with rare cells from a sample, removing cells not to be screened from the cell groups, and drawing the remaining cells as a cell suspension sample. An introduction device is activated to load the cell suspension sample onto an optically-induced dielectrophoresis chip including a cell isolation zone having a division arrangement wherein at least one optical pattern is configured on the cell isolation zone for screening, isolating and purifying the rare cells. The at least one optical pattern is configured to migrate, rotate or both. The at least one optical pattern is activated to attract the rare cells into a collection tank on the chip, and a liquid drawing device is activated to draw the rare cells out of the collection tank, thereby obtaining purified rare cells from the sample.

Abstract: The present invention provides a method and apparatus for amplifying a nucleic acid sequence by polymerase chain reaction (PCR). The method comprises placing a PCR sample in a container which is heated by only a single heat source that provides a high temperature for denaturation in the bottom of the PCR sample, while annealing and extension automatically occur in different regions of the PCR sample due to the convection induced by a temperature gradient descending from the bottom of the PCR sample to the surface of the PCR sample.
