  • Publication number: 20240088291
    Abstract: A transistor includes an insulating layer, a source region, a drain region, a channel layer, a ferroelectric layer, and a gate electrode. The source region and the drain region are respectively disposed on and in physical contact with two opposite sidewalls of the insulating layer. A thickness of the source region, a thickness of the drain region, and a thickness of the insulating layer are substantially the same. The channel layer is disposed on the insulating layer, the source region, and the drain region. The ferroelectric layer is disposed over the channel layer. The gate electrode is disposed on the ferroelectric layer.

  • Patent number: 9125635
    Abstract: A sampling device for vaginal specimens is revealed. The sampling device for vaginal specimens includes a tubular unit whose one end is disposed with a sampling unit, and at least one hole arranged on side walls of the same end of the tubular unit. The other end of the tubular unit is disposed with a saclike body or is inserted with an injection unit so as to send solution through the tubular unit to the hole for flushing vagina. By the sampling unit, a flushed vaginal specimen is collected. Thus the collection procedures of the specimen are easy and convenient to be performed and users have no uncomfortable feelings due to the lubricant solution.

  • Publication number: 20150072947
    Abstract: The present invention uses methylomic analysis and discovers DNA methylation biomarkers for prediction of ovarian cancer prognosis and detection of malignant ovarian cancer. In addition to being independent prognostic factors for patients with current treatment protocols, these DNA methylations are important biomarkers for individualized medicine for future chemotherapy (especially the demethylation agents or other epigenetic drugs).

  • Patent number: 7820386
    Abstract: A method for screening cancer comprises the following steps: (1) providing a test specimen; (2) detecting the methylation state of the CpG sequence in at least one target gene within the genomic DNA of the test specimen, wherein the target genes is consisted of SOX1, PAX1, LMX1A, NKX6-1, WT1 and ONECUT1; and (3) determining whether there is cancer or cancerous pathological change in the specimen based on the presence or absence of the methylation state in the target gene; wherein method for detecting methylation state is methylation-specific PCR (MSP), quantitative methylation-specific PCR (QMSP), bisulfite sequencing (BS), microarrays, mass spectrometer, denaturing high-performance liquid chromatography (DHPLC), and pyrosequencing.
