. Chan, Winnie Kwai Yu; Hui, Wun Fung 2016-10-01 High-dose methotrexate therapy (HDMTX) is a common form of chemotherapy used in children with high-grade malignancy such as osteosarcoma. Treatment with HDMTX requires careful monitoring of drug levels with folinic acid ( leucovorin) rescue therapy. Toxicity from methotrexate is not uncommon and sometimes causes significant morbidity and mortality.

We report an 11-year-old child whose 24-h post-HDMTX serum level was 651.8 μmol/L (recommended level. Damonte, Kathleen 2004-01-01 The term acid rain describes rain, snow, or fog that is more acidic than normal precipitation. To understand what acid rain is, it is first necessary to know what an acid is. Acids can be defined as substances that produce hydrogen ions (H+), when dissolved in water. Scientists indicate how acidic a substance is by a set of numbers called the pH.

Boyle, R.H.; Boyle, R.A. 1983-01-01 Acid rain, says Boyle is a chemical leprosy eating into the face of North America and Europe, perhaps the major ecological problem of our time.

Boyle describes the causes and scope of the phenomenon; the effects on man, wildlife, water, and our cultural heritage. He probes the delays of politicians and the frequent self-serving arguments advanced by industry in the face of what scientists have proved. The solutions he offers are to strengthen the Clean Air Act and require emission reductions that can be accomplished by establishing emission standards on a regional or bubble basis, burn low-sulfur coal, install scrubbersmore » at critical plants, and invest in alternative energy sources. 73 references, 1 figure.« less.

Sharma, Meenakshi; Li, Liya; Celver, Jeremy; Killian, Caroline; Kovoor, Abraham; Seeram, Navindra P. 2010-01-01 Recent data suggest that ellagitannins (ETs), a class of hydrolyzable tannins found in some fruits and nuts, may have beneficial effects against colon cancer.

In the stomach and gut, ETs hydrolyze to release ellagic acid (EA) and are converted by gut microbiota to urolithin-A (UA; 3,8-dihydroxy-6H-dibenzopyran-6-one) type metabolites which may persist in the colon through enterohepatic circulation. However, little is known about the mechanisms of action of either the native compounds or their metabolites on colon carcinogenesis.

Components of Wnt signaling pathways are known to play a pivotal role in human colon carcinogenesis and inappropriate activation of the signaling cascade is observed in 90% of colorectal cancers. Here we investigated the effects of UA, EA, and ET rich fruit extracts on Wnt signaling in a human 293T cell line using a luciferase reporter of canonical Wnt pathway-mediated transcriptional activation. The ET extracts were obtained from strawberry (Fragaria annassa), Jamun berry (Eugenia jambolana), and pomegranate (Punica granatum) fruit and were all standardized to phenolic content (as gallic acid equivalents, GAEs, by the Folin Ciocalteau method) and to EA content (by high performance liquid chromatography methods): strawberry=20.5% GAE, 5.0% EA; Jamun berry= 20.5% GAE, 4.2% EA; pomegranate= 55% GAE, 3.5% EA. The ET-extracts (IC50=28.0-30.0 μg/mL), EA (IC50=19.0 μg/mL; 63 μM) and UA (IC50=9.0 μg/mL; 39 μM) inhibited Wnt signaling suggesting that ET-rich foods have potential against colon carcinogenesis and that urolithins are relevant bioactive constituents in the colon.

Panthong, S; Boonsathorn, N; Chuchawankul, S 2016-10-17 Biological activities of various mushrooms have recently been discovered, particularly, immunomodulatory and antitumor activities. Herein, three edible mushrooms, Auricularia auricula-judae (AA), Pleurotus abalonus (PA) and Pleurotus sajor-caju (PS) extracted using Soxhlet ethanol extraction were evaluated for their antioxidative, anti-proliferative effects on leukemia cells.

Using the Folin-Ciocalteau method and Trolox equivalent antioxidant capacity assay, phenolics and antioxidant activity were found in all sample mushrooms. Additionally, anti-proliferative activity of mushroom extracts against U937 leukemia cells was determined using a viability assay based on mitochondrial activity.

PA (0.5 mg/mL) and AA (0.25-0.5 mg/mL) significantly reduced cell viability. Interestingly, PS caused a hormetic-like biphasic dose-response. Low doses (0-0.25 mg/L) of PS promoted cell proliferation up to 140% relative to control, whereas higher doses (0.50 mg/mL) inhibited cell proliferation.

Against U937 cells, AA IC 50 was 0.28 ± 0.04 mg/mL, which was lower than PS or PA IC 50 (0.45 ± 0.01 and 0.49 ± 0.001 mg/mL, respectively). Furthermore, lactate dehydrogenase (LDH) leakage conferred cytotoxicity.

PS and PA were not toxic to U937 cells at any tested concentration; AA (0.50 mg/mL) showed high LDH levels and caused 50% cytotoxicity. Additionally, UPLC-HRMS data indicated several phytochemicals known to support functional activities as either antioxidant or anti-proliferative. Glutamic acid was uniquely found in ethanolic extracts of AA, and was considered an anti-cancer amino acid with potent anti-proliferative effects on U937 cells. Collectively, all mushroom extracts exhibited antioxidant effects, but their anti-proliferative effects were dose-dependent.
