A broiler study was performed to determine the pre-cecal phosphorus (P) digestibility of 5 P sources, 3 from animal (Delfos, Calfos, and porcine bone meal) and 2 of inorganic (monocalcium phosphate [MCP] and dicalcium phosphate [DCP]) origin. Delfos is processed from bones resulting in a dicalcium phosphate product, and Calfos is processed from bones in which part of the gelatin is removed but in which the hydroxy-apatite matrix is preserved. During the first 14 d, birds were housed in floor pens bedded with wood shavings and received a commercial starter diet...

Bhishma P Patel, Arvind Kumar
In the present study, a defined mixed microbial consortium was investigated for their ability to utilize three different monochlorophenols (MCPs) and 2,4-DCP individually and in the mixture. None of the individual strains were able to utilize 3-CP and 4-CP, but when they were mixed to form defined consortium, they have shown great potential and degradation of high concentration of 3-CP and 4-CP. Spectrophotometric analysis of metabolites during MCPs degradation establishes the presence of 2-chloromaleylacetate...

The present investigation was undertaken to determine the distribution of 1,2-dichloropropane (DCP) in the blood, liver, kidney, lung, and abdominal fat of rats after oral administration. Male rats were orally administered 62 or 125 mg/kg body weight doses of DCP dissolved in corn oil by gavage, and the concentrations in the blood and tissues were measured. The DCP concentration in the abdominal fat was much greater than in the blood and other tissues. Twenty-four-hr after oral administration, DCP could still be detected in the blood and abdominal fat in the 62-mg/kg group, and in the blood, liver, kidney, lung, and abdominal fat in the 125-mg/kg group...

The aim of this study was to investigate lithium and 2,4-dichlorophenol (2,4-DCP)-induced circadian rhythm disorder and their genome-wide effects in zebrafish. Zebrafish larvae were exposed to 250 ppm LiCl (n = 40) or 20 ppm 2,4-DCP. RNA was subsequently extracted and determined quantitatively. The mRNA levels of circadian clock-related genes, including clock1a, bmal1b, per2, and per1b, were determined. Microarray datasets were generated and the differentially expressed genes (DEGs) were identified. The mRNA levels of some upregulated and downregulated DEGs were examined by quantitative real-time polymerase chain reaction (RT-PCR)...

1,2-dichloropropane (1,2-DCP), a synthetic chlorinated solvent, was recently classified as carcinogenic. Genotoxic events are known as a crucial step in the initiation of cancer. However, studies on the genotoxicity of 1,2-DCP are very limited, particularly studies investigating the mechanism behind DNA damage by 1,2-DCP. In this study, we examined the genotoxicity of 1,2-DCP using phosphorylated histone H2AX (γ-H2AX), a sensitive DNA damage marker. 1,2-DCP showed dose- (1-10 mM: 4 h) and time-dependent (1-24 h: 5 mM) γ-H2AX generation in cultured human hepatocytes (WRL-68) and cholangiocytes (MMNK-1)...

Benzalkonium chlorides (BACs), as typical cationic surfactants and biocides widely applied in household and industrial products, have been frequently detected as micropollutants in many aquatic environments. In this study, the combination of UV irradiation and chlorine (UV/chlorine), a newly interested advanced oxidation process, was used to degrade dodecylbenzyldimethylammonium chloride (DDBAC). UV/chlorine showed synergistic effects on DDBAC degradation comparing to UV irradiation or chlorination alone. Radical quenching experiments indicated that degradation of DDBAC by UV/chlorine involved both UV photolysis and radical species oxidation, which accounted for 48...

OBJECTIVES: Diabetic cystopathy (DCP), characterized by peripheral neuropathy-associated bladder dysfunction, is a common urinary complication in patients with diabetes (~80%). Bone marrow mesenchymal stem cell (BMMSC) transplantation, a new and emerging regenerative therapy, provides a curative option for DCP. However, the application of this therapy is limited by the low survival rate and engraftment of transplanted stem cells. This study was undertaken to determine whether integrin-linked kinase (ILK) overexpression would improve stem cell survival and engraftment after BMMSC transplantation...

The reaction between persulfate (PS) and carbon nanotubes (CNTs) for the degradation of 2,4-dichlorophenol (2,4-DCP) was investigated. It was demonstrated that CNTs could efficiently activate PS for the degradation of 2,4-DCP. Results suggested that the neither hydroxyl radical (OH) nor sulfate radical (SO4(-)) was produced therein. For the first time, the generation of singlet oxygen ((1)O2) was proved by several methods including electron paramagnetic resonance spectrometry (EPR) and liquid chromatography mass spectrometry measurements...

Pseudokirchneriella subcapitata is a sickle-shaped freshwater green microalga that is normally found in unicellular form. Currently, it is the best known and most frequently used species of ecotoxicological bioindicator because of its high growth rate and sensitivity to toxicants. However, despite this organism's, our knowledge of its cell biology-for example, the patterns of nuclear and cytoplasmic division in the mitotic stage-is limited. Although it has been reported that P. subcapitata proliferates by popularity forming four daughter cells (autospores) through multiple fission after two nuclear divisions, here, we report two additional reproductive patterns by which two autospores are formed by binary fission ("two-autospore type") and eight autospores are formed by multiple fission ("eight-autospore type")...
