In Nicotiana suaveolens N. tabacum hybrid cells incubated with high levels (0.8, 4.0 or 20 mM) of BAP at 28°C, the percentage of dead cells and extent of nuclear fragmentation were suppressed and some cultured cells remained green compared with those incubated with a standard level (0.04 mM) of BAP. Though DNA ladders were detected in all hybrid cells incubated at 28°C, positive signals for TUN...

It is possible to increase the sampling resolution and the available information on zooplankton populations by applying acoustic sampling techniques. Knowledge of an organism’s acoustic target strength (TS) is critical for translating acoustic data into meaningful biological information, such as numerical abundance. We have taken several approaches to evaluate the acoustic TS of Mysis relicta, ...

the methylotrophic thermo tolerant actinomycete strain 381, was isolated from a compost sample, assimilated methanol during growth. methanol dehydrogenase could not be detected in cell extracts using dye-linked assays in the absence of nad+. dichlorophenol-indophenol-linked methanol oxidation was detected in broken cell suspensions in the presence of nad+ and the absence of cyanide. taxonomic s...

BACKGROUND We evaluated the impact of radiation, reconstruction, and timing of tracheoesophageal puncture (TEP) on complications and speech outcomes. METHODS Retrospective review identified 145 patients who underwent TEP between 2003 and 2007. RESULTS Ninety-nine patients (68%) had primary and 46 (32%) had secondary TEP, with complications occurring in 65% and 61%, respectively (p = .96). T...

There has been recent concern about the association between high dose methadone and prolongation of QTc in the electrocardiogram. QTc is the time from the beginning of the QRS complex to the end of the T have as measured on an electrocardiogram and corrected for heart rate. To date, no association has been made between methadone and buprenorphine in commonly used doses and prolonged QTc. Electr...

Neural stem cells are self-renewing, multipotent and undifferentiated precursors that retain the capacity for differentiation into both glial (astrocytes and oligodendrocytes) and neuronal lineages. Neural stem cells offer cell-based therapies for neurological disorders such as Alzheimer's disease, Parkinson's disease, Huntington's disease and spinal cord injuries. However, their cellular behav...
