BACKGROUND The evaluation of infant meconium as a cumulative matrix of prenatal toxicant exposure requires comparison to established biomarkers of prenatal exposure. METHODS We calculated the frequency of detection and concentration of tobacco smoke metabolites measured in meconium (nicotine, cotinine, and trans-3'-hydroxycotinine concentrations) and three serial serum cotinine concentrations...
Determination of iodine in biological material presents technical problems because of the large amounts of organic material present and because the concentration of iodine is often low. Many workers have used a chloric acid-digestion procedure (1), but this is tedious, and Richmond (2) found it less satisfactory for accurate measurement of fecal iodine than for determining iodine in serum or ur...
In this paper, we investigate the relation between two variables where the one is measured with the ratio or interval scale and the other with the nominal. In this cases, we use from serial correlation coefficient. Computation of some serial coefficient such as biserial and point-biserial coefficient is carried out with some examples and R program.
Elevated concentrations of progesterone receptor, a sensitive indicator of estrogen responsiveness, have been measured in this study during early serial transplan tation of estrogen-induced renal adenocarcinoma tissue in hamsters. A new approach of tumor transplantation beneath the renal capsule has been used. Fragments of primary tumor tissue transplanted subpannicularly in es trogen-treated h...

the aim of the present study was to determine the in?uence of presence or absence of corpus luteum (cl) on hormonal and metabolites composition of follicular ?uid (ff) harvested from different sized follicles and its relationship with blood serum concentrations in sanjabi ewes. ovaries and blood samples were collected from 60 clinically healthy adult ewes (sanjabi breed) 1–3 years of age in dio...
