In response to demands for reliable alternatives to collection of venous specimens for determination of whole blood lead levels in children, the Centers for Disease Control has called for increased research into capillary methodologies. In this study, a three tiered approach was developed to assess the adequacy of capillary specimens for determining whole blood lead. Patient blood lead results ...
Immunoassay is widely employed as a highly sensitive, specific analytical method for hormones and drugs in biological samples. A technique utilizing capillary electrophoresis with laser-induced fluorescence detection was examined based on the reaction process of these immunoassays in order to develop a protocol characterized by high sensitivity and high speed. The conditions of the antigen-anti...
For a TeV energy particle physics, R&D of electron/positron linear colliders has been conducted very hard at many laboratories. Development of high field gradient cavities is one of key issues to realize such a machine. Field emission loading is a dominant phenomenon limiting high field. Particulate contamination on the inner surface is a main source of field emission. In this paper, we report ...
background: recently different studies suggested that discontinuation of gonadotrophin releasing hormone analogue (gnrha) at beginning of ovarian stimulation (improvement of ovarian response to gonadotrophins) may have some benefit to poor responder patients in invitro fertilization (ivf) cycles. objective:the efficacy of gnrha stop protocol in poor responder patients in ivf cycles was assessed...
objective: this study was conducted to compare the results of fixed versus flexible gnrh antagonist protocols in controlled ovarian stimulation for intra cytoplasmic sperm injection (icsi) in patients with pcos. materials and methods: a randomized clinical trial was performed on 100 pcos women, who were admitted to a tertiary infertility clinic and were candidate for ivf/icsi. they were divided...
T he ban on chlorofluorocarbons (CFCs) hit users squarely in their degreasers. In the search for viable alternative cleaning processes, the first task was to determine evaluation criteria. When is a product sufficiently clean? How do we know when it’s properly rinsed? At what point is it adequately dry? After seeking out suitable non-CFC cleaning agents, we next sized up equipment best suited f...
In this report, we present a PCR protocol for rapid identification of enterohemorrhagic Escherichia coli on a LightCycler instrument. In a multiplex assay, the genes encoding Shiga toxin 1 and Shiga toxin 2 are detected in a single reaction capillary. A complete analysis of up to 32 samples takes about 45 min.
We describe the formation and structure of nucleolipid/dendrimer multilayer films controlled by non-covalent interactions to obtain biomaterials that exhibit molecular recognition of nucleic acids. Layers of cationic poly(amidoamine) (PAMAM) dendrimers of generation 4 and the anionic nucleolipids 1,2-dilauroyl-sn-glycero-3-phosphatidylnucleosides (DLPNs) based on uridine (DLPU) and adenosine (D...
