Dechlorination of hexachlorobenzene (HCB) was achieved by a mixture of commercial CaO and alpha-Fe2O3 (CaO/alpha-Fe2O3) in closed systems at temperatures of 300 degrees C and 350 degrees C, which exhibited a synergic effect compared to CaO or alpha-Fe2O3 alone, and the dechlorination efficiency was dramatically enhanced. When CaO and alpha-Fe2O3 coexisted, HCB was dechlorinated by about 98% aft...

Cimicifugoside is a triterpenoid originating from the rhizomes of Cimicifuga simplex, and acts to inhibit the subcellular transport of nucleosides. Cimicifugoside, when used in combination with methotrexate, showed a cellspecific synergic effect on the promonocytic leukemia cell line U937, but not on the chronic myelogenetic leukemia cell line K562. Thymidine uptake was more severely inhibited ...

BACKGROUND According to the development of resistant strains of pathogenic bacteria following treatment with antimicrobial chemotherapeutic agents, alternative approaches such as lethal photosensitization are being used. The aim of this study was to evaluate the effect of visible light and laser beam radiation in conjugation with three different photosensitizers on the survival of two main peri...

The hypophyseal substance-the synergic factor-which gives increased gonadotropic effects when combined with prolan has been shown to itself possess a definite though slight gonadotropic activity. It produces transitory follicular enlargement within 24-48 hours, which, however, regresses at once on cessation of treatment so that by the end of the 4th day the ovary again approximates its infantil...

several factors effect on sorption of polycyclic aromatic hydrocarbons (pahs) in soil. co-existence of metals and organic matter of soil are among important affecting factors on sorptive behavior of pahs. this research investigated the effect of organic matter content and heavy metals (lead, nickel and zinc), on sorption of phenanthrene onto kaolinite. for this purpose, sorption of the organic ...

Combining with the synergic effect of carbon nanotubes and ionic liquids for enhancing electrochemiluminescence (ECL) response of CdSe QDs, a universal strategy for highly sensitive biosensing was designed. Using alpha-fetoprotein as a model and monitoring the variation of ECL intensity before and after immunoreaction, a label-free ECL biosensor was developed.

Simultaneously surface fluorinated and platinized TiO2 (F-TiO2/Pt) exhibits a novel photocatalytic activity for the anoxic degradation of organic compounds, which is attributed to the unique synergic effect of surface fluorination and platinization on the photo-induced charge transfer process.
