HPLC columns packed with 3 microm particle size HPLC Technology Techsphere SCX (propylsulfonic acid-modified) silica offer considerable advantages over 5 microm SCX packings in the analysis of basic drugs using 100% methanol eluents containing an ionic modifier such as ammonium
The U.S. EPA Endocrine Disruptor Screening Program (EDSP) Tier 1 male pubertal protocol was designed as a screen to detect endocrine-disrupting chemicals which may alter reproductive development or thyroid function. One purpose of this in vivo screening protocol is to

Perchlorate, a known thyroid disruptor, is deposited in eggs of exposed female birds, raising concerns that the embryos from these eggs may become hypothyroid, which may in turn affect the development and function of thyroid-dependent organs. We hypothesized that exposure

An energetic coordination compound Cu(Mtta)(2)(NO(3))(2) has been synthesized by using 1-methyltetrazole (Mtta) as ligand and its structure has been characterized by X-ray single crystal diffraction. The central copper (II) cation was coordinated by four O atoms from two Mtta ligands

A recent study further investigated the potential effects of maternal thyroid function and morphology on fetal development upon maternal exposure to ammonium perchlorate during gestation and lactation. Female Sprague-Dawley rats (25/group) were given continual access to 0 (carrier), 0.01, 0.1
