  • genital
  • At Visit 2 (cycle days 20-25), after it has been confirmed that the participant meets all of the inclusion criteria and none of the exclusion criteria, genital samples will be taken and she will be given 2 applicators of tenofovir 1% gel to insert two hours apart. (clinicaltrials.gov)
  • At Visit 3 (cycle days 20-25), blood and genital samples will be collected. (clinicaltrials.gov)
  • She will be instructed to return approximately 3 or 11 hours after insertion of the second gel for Visit 4 (cycle days 5-10) and blood and genital samples will be taken. (clinicaltrials.gov)
  • Measures
  • Using a repeated-measures design on a large study sample, our purpose was to determine whether ovarian cycle-phase affects maximal exercise performance (V̇ O 2 max ) in women who had lived at an altitude of 3600 m since birth or early childhood. (biologists.org)
  • process
  • The cell-division cycle is a vital process by which a single-celled fertilized egg develops into a mature organism, as well as the process by which hair, skin, blood cells, and some internal organs are renewed. (wikipedia.org)
  • Heat recovered from the anode-side process can be used by a power-generating bottoming cycle consisting of a heat recovery steam generator and steam turbine. (wikipedia.org)
  • The process is basically similar to the atmospheric-pressure cycle, but it would run the SOFC module at elevated pressure, achieving an SOFC voltage boost, and would replace the cathode-side process-air blower with an air compressor. (wikipedia.org)
  • high
  • During this phase, the biosynthetic activities of the cell, which are considerably slowed down during M phase, resume at a high rate. (wikipedia.org)
  • However, fuels cells operating at high temperature such as the solid oxide fuel cell (SOFC) are not poisoned by carbon monoxide and carbon dioxide, and in fact can accept hydrogen, carbon monoxide, carbon dioxide, steam, and methane mixtures as fuel directly, because of their internal shift and reforming capabilities. (wikipedia.org)
  • the IGFC power plant is analogous to an integrated gasification combined cycle power plant, but with the gas turbine power generation unit replaced with a fuel cell (high temperature type such as SOFC) power generation unit. (wikipedia.org)
  • Due to the inherently efficient SOFC, and to using recovered SOFC exhaust heat to generate additional electric power, an IGFC system is capable of operating at a high electric efficiency that significantly exceeds those associated with conventional pulverized coal and integrated gasification combined cycle power systems. (wikipedia.org)
  • Positive feedback loops play a role by switching cells from low to high Cdk-activity. (wikipedia.org)
  • major
  • Typical major components of the IGFC system, this one centered on a SOFC module running at atmospheric pressure, are identified in the simplified cycle diagram. (wikipedia.org)
  • known
  • Within the cell cycle, there is a stringent set of regulations known as the cell cycle control system that controls the timing and coordination of the phases to ensure a correct order of events. (wikipedia.org)
  • Biochemical triggers known as cyclin-dependent kinases (Cdks) switch on cell cycles events at the corrected time and in the correct order to prevent any mistakes. (wikipedia.org)
  • Between the beginning of the G1 phase (which is also after mitosis has occurred) and R, the cell is known as being in the G1-pm subphase, or the post-mitotic phase. (wikipedia.org)
  • After R and before S, the cell is known as being in G1-ps, or the pre S phase interval of the G1 phase. (wikipedia.org)
  • For example, the set of carboxylic acids that are best known as the intermediates in the citric acid cycle are present in all known organisms, being found in species as diverse as the unicellular bacterium Escherichia coli and huge multicellular organisms like elephants. (wikipedia.org)
  • typically
  • To replicate their genomes in cells and generate new progeny, viruses typically require factors provided by the cells that they have infected. (springer.com)
  • Previously it was called resting stage because there is no apparent activity related to cell division.Typically interphase lasts for at least 90% of the total time required for the cell cycle. (wikipedia.org)
  • Lower-temperature fuel cell types such as the proton exchange membrane fuel cell, phosphoric acid fuel cell, and alkaline fuel cell require pure hydrogen as fuel, typically produced from external reforming of natural gas. (wikipedia.org)
  • early
  • Unfortunately, several difficulties have prevented realiza- tion of the early promise of cell cycle analysis: Proliferative patterns of the normal and malignant tissues have been found to be substantially more complex than originally an- ticipated, and synchronization of human tumors has proved remarkably difficult. (springer.com)
  • cancer
  • Quantification of the proliferative characteristics of normal and malignant cells has been of interest to oncolo- gists and cancer biologists for almost three decades. (springer.com)
  • I experienced a sense of wholeness that the extraordinary diversity of life was built on common principles, and that this advance in understanding of how the cell-cycle was regulated would have many implications for the reproduction, growth and development of all living organisms, and for diseases like cancer. (springer.com)
  • human
  • Human tumors of the same type have proved highly variable, and the cytokinetic tools available for cell cycle analysis have been labor intensive, as well as somewhat subjective and in many cases inapplicable to humans. (springer.com)
  • specific
  • for example, by allowing identi- fication of rapidly proliferating tumors against which cell cycle-specific agents could be used with maximum effec- tiveness and by allowing rational scheduling of cell cyc- specific therapeutic agents to maximize the therapeutic ratio. (springer.com)
