We present a new approach for determining the strength of the dipolar solute-induced reaction field, along with the ground- and excited-state electrostatic dipole moments and polarizability of a solvated chromophore, using exclusively one-photon and two-photon absorption measurements. We verify the approach on two benchmark chromophores N,N-dimethyl-6-propionyl-2-naphthylamine (prodan) and coum...

Recently, the effect of exposure to persistent organic pollutants (POPs) on sperm concentration was only seen in men with a short androgen receptor (AR) gene CAG repeat. In order to investigate whether these effects could be observed also in vitro, we tested the impact of 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153) and 1,1-bis-(4-chlorophenyl)-2,2-dichloroethene (4,4'-DDE) on 5α-dihydrotestoster...

As a surface functional material, super-hydrophobic coating has great application potential in wind turbine blade anti-icing, self-cleaning and drag reduction. In this study, ZnO SiO2 multi-scale superhydrophobic coatings with mechanical flexibility were prepared by embedding modified nanoparticles PDMS. The higher static water contact angle (CA is 153°) lower rolling (SA 3.3°), showing excelle...

This study evaluates and quantifies the interactive hepatic tumor promoting effects of two PCBs, the Ah receptor agonist PCB 126 (3,3',4,4',5-pentachlorobiphenyl) and the constitutive androstane receptor (CAR) agonist PCB 153 (2,2',4,4',5,5'-hexachlorobiphenyl). Promotion of altered hepatic foci was evaluated utilizing a medium-term 8-week bioassay for promoters of hepatocarcinogenesis. The ass...

Multilingual generation is becoming an increasingly important aspect of implemented systems that showcase the abilities of generation systems. Most such systems require multiple grammars, one for each language which must be deployed. Yet little is known about the development costs for additional languages which are developed not from scratch, but by adapting existing resources. We ported a stan...

PURPOSE Exposing human tumor cells to sublethal doses of external beam radiation up-regulates expression of tumor antigen and accessory molecules, rendering tumor cells more susceptible to killing by antigen-specific CTLs. This study explored the possibility that exposure to palliative doses of a radiopharmaceutical agent could alter the phenotype of tumor cells to render them more susceptible ...

aim : this study evaluated the results and efficacy of serum ca 19-9 in determining the nature of a pancreatic solid mass in patients referred for investigation of possible malignancy. background : a wide variety of tumor markers have been proposed for pancreatic cancer but currently the only one with any practical usefulness for diagnosis, prognosis, and monitoring of treatment is “ca 19-9 ”. ...
