Purpose: To assess clinical outcomes after using IG-IMRT for palliation among patients with advanced cancers. Methods: Patients with advanced and/or metastatic cancers were treated on our Tomo-PAL (Tomotherapy-Planning and Administration Linked) protocol using helical TomoTherapy and evaluated to assess clinical efficacy of treatment as well as to assess side effects. Results: A total of 40 pat...

Axial transcranial sonogram (mesencephalic level): Butterfly-shaped midbrain was encircled for better visualization (solid lines). Arrows indicate the coiled distal ICA aneurysm. He was monitored via daily transcranial sonography (TCS) for the potential develo...

N2O emission in the anaerobic ammonium oxidation (anammox) process is of growing concern. In this study, effects of substrate concentrations on N2O emissions were investigated in an anammox reactor. Extremely high N2O emissions of 1.67 % were led by high NH4-N concentrations. Results showed that N2O emissions have a positive correlation with NH4-N concentrations in the anammox reactor. Reducing...

The most abundant transition metal in biological systems is iron. It is incorporated into protein cofactors and serves either catalytic, redox or regulatory purposes. Anaerobic ammonium oxidizing (anammox) bacteria rely heavily on iron-containing proteins - especially cytochromes - for their energy conservation, which occurs within a unique organelle, the anammoxosome. Both their anaerobic life...

The purpose of this work was to evaluate differences in dose resulting from the use of copper aperture inserts compared to lead-alloy (Cerrobend) aperture inserts for electron beam therapy. Specifically, this study examines if copper aperture inserts can be used clinically with the same commissioning data measured using lead-alloy aperture inserts. The copper inserts were acquired from .decimal...

Nitrogen fixation is an essential process that biologically transforms atmospheric dinitrogen gas to ammonia, therefore compensating for nitrogen losses occurring via denitrification and anammox. Currently, inputs and losses of nitrogen to the ocean resulting from these processes are thought to be spatially separated: nitrogen fixation takes place primarily in open ocean environments (mainly th...

ABSTRACT The experiments carried out proved possibility for implementation of deamonification process in membrane-assisted bioreactor. At the temperature above 30°C, dissolved oxygen concentration below 0.8 mg O2/L and at the very low contents of biodegradable organic compounds within 1 month of process operation stable nitrite and ammonia nitrogen concentrations were reached at the levels resp...

BACKGROUND Polyamines have various biological functions including marked effects on the structure and function of genomic DNA molecules. Changes in the higher-order structure of DNA caused by polyamines are expected to be closely related to genetic activity. To clarify this issue, we examined the relationship between gene expression and the higher-order structure of DNA under different polyamin...

The polyamines spermidine and spermine and their diamine precursor putrescine are essential for mammalian cell growth and viability, and strategies are sought for reducing polyamine levels in order to inhibit cancer growth. Several structural analogues of the polyamines have been found to decrease natural polyamine levels and inhibit cell growth, probably by stimulating normal feedback mechanis...
