Most herbivores eat more and survive better when they have access to a variety of foods. One explanation involves the detoxification of plant secondary metabolites (PSMs). By feeding from a variety of plants that contain different classes of PSMs, animals can use multiple detoxification pathways and presumably consume more food. Although popular, this theory is difficult to test because it requ...

Methylated forms of arsenic (As), monomethylarsenate (MMA), and dimethylarsenate (DMA) have historically been used as herbicides and pesticides. Because of their large application to agriculture fields and the toxicity of MMA and DMA, the persistency of these compounds in the environment is of great concern. MMA and DMA sorption and desorption were investigated in soils, varying in mineralogica...

This work demonstrates an alternative method to prepare allylated arenes and aryl-substituted allylic esters via catalytic decarboxylative C-C bond formation using aromatic carboxylic acids and allylic halides and esters.

Nickel hydrides supported by a terphenyl diphosphine were synthesized and found to undergo nickel-to-arene H-transfers. Some of the resulting complexes also undergo the reverse (C-to-Ni) H-migration, indicating the potential for storing H-equivalents in this type of pincer ligand. NMR spectroscopy, single crystal X-ray diffraction, and isotopic labeling studies investigating the mechanism of th...

DETOXIFICATION: A GENERAL OVERVIEW James L. Wilson D.C., N.D., Ph.D. From the late 1800s until recently, the value and use of detoxification have been championed mainly by the naturopathic profession and those interested in natural health. However, with the emergence of increasingly sophisticated laboratory tests and the growing influence of natural medicine, detoxification is gaining recogniti...

The anti-neoplastic prodrug, cyclophosphamide, requires biotransformation to phosphoramide mustard (PM), which partitions to volatile chloroethylaziridine (CEZ). PM and CEZ are ovotoxicants, however their ovarian biotransformation remains ill-defined. This study investigated PM and CEZ metabolism mechanisms through the utilization of cultured postnatal day 4 (PND4) Fisher 344 (F344) rat ovaries...

CD4(+)CD25(+)Foxp3(+) regulatory T (Treg) cells have been shown to play important roles in mediating cancer development. Although cyclophosphamide (CY) has shown promise as a drug to selectively target Treg cells with low-dose in vivo, the underlying molecular mechanism remains unclear. In this report, we provide evidence that ATP, the energy molecule and signal element, accounts for the select...

Background: Cyclophosphamide use is often limited by associated hematotoxicity. This study investigated the effects of melatonin on haematological indices in cyclophosphamide-induced hematotoxicity mice. Methods: Ninety mice weighing between 20-25 gm were randomly divided equally into nine groups (A-I). Group A (saline control) received 2 ml/kg intraperitoneal (i.p.) normal saline with 10 disti...

BACKGROUND AND PURPOSE Cyclophosphamide induces urotoxicity characterized by the development of cystitis, which involves bladder overactivity and inflammation. Here, we investigated the roles of chemokine receptor 2 (CXCR2) and transient receptor potential vanilloid 1 (TRPV1) channels in a rat model of cyclophosphamide-induced cystitis. EXPERIMENTAL APPROACH Cystitis induced by cyclophosphami...
