Several programs exist to control their numbers through lethal removal, using tools such as baiting with toxins. Adult male cats are especially difficult to control. We hypothesized that one way to capture these male cats is to lure them using female cats. As female cats are seasonal breeders, a method is needed to artificially induce reproductive (estrous) behavior so that they could be used for this purpose year-round (i.e., regardless of season). -
Exposure to Female Hormone Drugs During Pregnancy
British Journal of Cancer (1999) 80(7), 1092–1097 © 1999 Cancer Research Campaign Article no. bjoc.1998.0469 Exposure to female hormone drugs during pregnancy: effect on malformations and cancer E Hemminki, M Gissler and H Toukomaa National Research and Development Centre for Welfare and Health, Health Services Research Unit, PO Box 220, 00531 Helsinki, Finland Summary This study aimed to investigate whether the use of female sex hormone drugs during pregnancy is a risk factor for subsequent breast and other oestrogen-dependent cancers among mothers and their children and for genital malformations in the children. A retrospective cohort of 2052 hormone-drug exposed mothers, 2038 control mothers and their 4130 infants was collected from maternity centres in Helsinki from 1954 to 1963. Cancer cases were searched for in national registers through record linkage. Exposures were examined by the type of the drug (oestrogen, progestin only) and by timing (early in pregnancy, only late in pregnancy). There were no statistically significant differences between the groups with regard to mothers’ cancer, either in total or in specified hormone-dependent cancers. The total number of malformations recorded, as well as malformations of the genitals in male infants, were higher among exposed children. The number of cancers among the offspring was small and none of the differences between groups were statistically significant. The study supports the hypothesis that oestrogen or progestin drug therapy during pregnancy causes malformations among children who were exposed in utero but does not support the hypothesis that it causes cancer later in life in the mother; the power to study cancers in offspring, however, was very low. -
Determination of 17 Hormone Residues in Milk by Ultra-High-Performance Liquid Chromatography and Triple Quadrupole Mass Spectrom
No. LCMSMS-065E Liquid Chromatography Mass Spectrometry Determination of 17 Hormone Residues in Milk by Ultra-High-Performance Liquid Chromatography and Triple Quadrupole No. LCMSMS-65E Mass Spectrometry This application news presents a method for the determination of 17 hormone residues in milk using Shimadzu Ultra-High-Performance Liquid Chromatograph (UHPLC) LC-30A and Triple Quadrupole Mass Spectrometer LCMS- 8040. After sample pretreatment, the compounds in the milk matrix were separated using UPLC LC-30A and analyzed via Triple Quadrupole Mass Spectrometer LCMS-8040. All 17 hormones displayed good linearity within their respective concentration range, with correlation coefficient in the range of 0.9974 and 0.9999. The RSD% of retention time and peak area of 17 hormones at the low-, mid- and high- concentrations were in the range of 0.0102-0.161% and 0.563-6.55% respectively, indicating good instrument precision. Method validation was conducted and the matrix spike recovery of milk ranged between 61.00-110.9%. The limit of quantitation was 0.14-0.975 g/kg, and it meets the requirement for detection of hormones in milk.

Raloxifene Hydrochloride
NEW ZEALAND DATASHEET 1. EVISTA® EVISTA 60 mg tablet 2. QUALITATIVE AND QUANTITATIVE COMPOSITION The active ingredient in Evista tablets is raloxifene hydrochloride. Each film coated tablet contains 60-mg raloxifene hydrochloride, which is equivalent to 56-mg raloxifene free base. For the full list of excipients, see 6.1 List of excipients. 3. PHARMACEUTICAL FORM Film coated tablet. 4. CLINICAL PARTICULARS 4.1 Therapeutic indications EVISTA is indicated for the prevention and treatment of osteoporosis in post-menopausal women. EVISTA is indicated for the reduction in the risk of invasive breast cancer in postmenopausal women with osteoporosis. EVISTA is indicated for the reduction in the risk of invasive breast cancer in postmenopausal women at high risk of invasive breast cancer. High risk of breast cancer is defined as at least one breast biopsy showing lobular carcinoma in situ (LCIS) or atypical hyperplasia, one or more first-degree relatives with breast cancer, or a 5-year predicted risk of breast cancer >1.66% (based on the modified Gail model). Among the factors included in the modified Gail model are the following: current age, number of first-degree relatives with breast cancer, number of breast biopsies, age at menarche, nulliparity or age of first live birth. Currently, no single clinical finding or test result can quantify risk of breast cancer with certainty. 4.2 Dose and method of administration The recommended dosage is one 60-mg EVISTA tablet per day orally, which may be taken at any time of day without regard to meals. No dose adjustment is necessary for the elderly. -

Background: There has recently been renewed corticosteroids, estrogens, sipuleucel T and, more recently, interest in the use of estrogens as a treatment strategy for CYP17 inhibitor (abirateron acetate) and androgen castration-resistant prostate cancer (CRPC). The purpose of receptor antagonist (enzaltamide) (2-7). Treatment with this study was to evaluate the feasibility and efficacy of estrogens was used as a palliative therapy for advanced ethinylestradiol re-challenge (re-EE) in the management of prostate cancer, however, the discovery of luteinizing CRPC. Patients and Methods: Patients with metastatic CRPC hormone-releasing hormone (LH-RH) agonists led them to who received re-EE after disease progression on prior EE become less common and they stopped being used in most and other therapy were retrospectively reviewed for prostate- countries in the 1980s (8). One of the reasons for reduction specific antigen (PSA) response, PSA progression-free in their use is the risk of cardiovascular and survival (P-PFS) and adverse events. Results: Thirty-six re- thromboembolic events during therapy. However, several EE treatments were performed for 20 patients. PSA response reports demonstrated the positive oncological results of to the initial EE treatment was observed in 14 (70%) patients. therapy with estrogens, such as diethylstilbestrol (DES) PSA response to re-EE was 33.3% in 36 re-EE treatments. -
