The objective of the present study was to determine whether Fyn kinase participated in signaling events during sperm-egg interactions, sperm incorporation, and meiosis II. The functional requirement of Fyn kinase activity in these events was tested through the use of the protein kinase inhibitor SKI-606 (Bosutinib) and by analysis of Fyn-null oocytes.(More)
Mitochondrial diseases include a group of maternally inherited genetic disorders caused by mutations in mtDNA. In most of these patients, mutated mtDNA coexists with wild-type mtDNA, a situation known as mtDNA heteroplasmy. Here, we report on a strategy toward preventing germline transmission of mitochondrial diseases by inducing mtDNA heteroplasmy shift(More)
It is difficult to determine dopamine (DA) and 5-hydroxytryptamine (5-HT) accurately because of the interference of ascorbic acid (AA) in vitro, which has a high concentration and can be oxidized at a potential close to DA and 5-HT at a conventional electrode, combined with the overlapping voltammetric signal of DA and 5-HT at a bare electrode. Herein,(More)
Carcinoembryonic antigen (CEA) has been an extensively used tumor marker responsible for clinical early diagnosis of cervical carcinomas, and pancreatic, colorectal, gastric and lung cancer. Combined with micro-electro mechanical system (MEMS) technology, it is important to develop a novel immune microelectrode array (MEA) not only for rapid analysis of(More)
association with the Czech Academy of Sciences. This meeting assembled more participants than any of the past TT meetings with a total of more than 700 researchers, students and technicians from close to 40 countries around the world. The venue for the meeting was the very modern Clarion Congress Hotel Prague and was organized by Guarant International who(More)
Vesicular exocytosis is ubiquitous, but it is difficult to detect within the cells' communication mechanism. For this purpose, a 2 µm ultramicrodic carbon fiber electrode was fabricated in this work based on electrodeposition with over-oxidized polypyrrole nanoparticle (PPyox-CFE), which was applied successfully for real-time monitoring of quantal(More)
Detection of tumor marker is an effective and low cost means in the early diagnosis of lung cancer, especially multiple tumor markers combined can improve the diagnostic value. In this paper, a chemiluminescence immunoassay using bio-functionlized magnetic nanocomposites (BFMNs) was proposed for simultaneous detection of multiple tumor markers.(More)
