OBJECTIVE We examined the interrelationships of pituitary thyrotropin (TSH) with circulating thyroid hormones to determine whether they were expressed either invariably or conditionally and distinctively related to influences such as levothyroxine (L-T4) treatment. DESIGN AND METHODS This prospective study employing 1912 consecutive patients analyses the interacting equilibria of TSH and free...
Background: Optic neuritis is an inflammation of the optic nerve. Because of importance of vision for human, management of optic neuritis is an important issue in neurology. Objectives: This study aimed at assessing the effect of oral steroid treatment after intravenous (IV) methylprednisolone therapy on demyelinating optic neuritis. Materials & Methods: 60 Patients with first episode of acut...
BACKGROUND The optimal ways of using aromatase inhibitors or tamoxifen as endocrine treatment for early breast cancer remains uncertain. METHODS We undertook meta-analyses of individual data on 31,920 postmenopausal women with oestrogen-receptor-positive early breast cancer in the randomised trials of 5 years of aromatase inhibitor versus 5 years of tamoxifen; of 5 years of aromatase inhibito...
The objective of this study was to determine the effects of supplementing fish oil (FO) in the drinking water of dairy cows on production performance and milk fatty acid composition. Sixteen multiparous Holstein dairy cows (741 +/- 84 kg of BW; 60 +/- 2.3 d in milk, mean +/- SD) housed in a tie-stall facility were used in the study. The study was conducted as a completely randomized design with...
OBJECTIVE To assess the impact of women's breast cancer risk factors (use of hormone therapy, family history of breast cancer, previous breast biopsy) on radiologists' mammographic interpretive performance and whether the influence of risk factors varies according to radiologist characteristics. STUDY DESIGN AND SETTING Screening mammograms (n=638,947) performed from 1996 to 2005 by 134 radio...

The relationship between barometric pressure (BARO) and maximum (MAX_T) and minimum (MIN_T) environmental temperatures with the incidence of parturition in beef cows was examined through exploratory data analysis. Spring- and fall-calving records from a 5-yr period (2005 through 2009) collected at the University of Arkansas, Livestock and Forestry Research Station (Batesville) and the Departmen...
BACKGROUND Cisplatin and gemcitabine is the standard first-line chemotherapy regimen for patients with advanced biliary tract cancer; expression of VEGF and its receptors is associated with adverse outcomes. We aimed to assess the effect of the addition of cediranib (an oral inhibitor of VEGF receptor 1, 2, and 3) to cisplatin and gemcitabine on progression-free survival. METHODS In this mult...
BACKGROUND/AIM Research has shown that chemoprevention may be effective against the development of lung cancer. The purpose of the present study was to evaluate the effect of oral chemoprevention in a mouse model of tobacco carcinogen-induced lung tumor. MATERIALS AND METHODS A total of 60 A/J mice were randomized to a normal diet, a diet with low calcium, or a chemoprevention diet with acety...
