Experiment 1 was repeated for 5 consecutive days and Exp. 2 was repeated for 4 consecutive days. Data on reaction time, number of mounts, semen volume, semen concentration, sperm wave motion, and progressive linear motion (Exp. 1 only) were collected and analyzed as a randomized complete block design, where rams were initially blocked for breed and age. In Exp. 1, there was an effect of day (P < 0.05) and a treatment x day interaction (P < 0.05) on semen volume, whereas there was also an effect of treatment (P < 0.05) and day (P < 0.01) on semen concentration,

which was most evident on d 1. In Exp. 2, there was an effect of treatment on reaction time (P < 0.05) and semen volume (P = 0.08), which was most evident on d 1. This study demonstrates an acute effect on d 1 on semen concentration Bafilomycin A1 mechanism of action when rams were exposed to the sight and smell of a ewe

in estrus. Alternatively, when rams were stimulated with physical contact of a ewe in estrus, an acute increase in semen volume was evident on d 1. These effects were not evident on subsequent days and thus the overall benefits on ram libido and semen quality of exposing rams to ewes in estrus are minimal.”
“Objectives To estimate the interval cancer incidence, its determinants and the episode sensitivity in the Norrbotten Mammography Screening Programme (NMSP).\n\nSetting Since 1989, women

aged 40-74 years (n = 55,000) have been invited to biennial screening by the NMSP, Norrbotten county, CA4P Sweden.\n\nMethods Data on 1047 invasive breast cancers from six screening rounds of the NMSP (1989-2002) were collected. We estimated the invasive interval cancer rates, rate ratios and the episode sensitivity using the detection and incidence methods. A linear Poisson-model was used to analyse association between interval cancer incidence and sensitivity.\n\nResults 768 screen-detected and 279 interval cancer cases were identified. The rate ratio of interval cancer decreased with age. The 50-59 year age group showed the highest rate buy AZD6738 ratio (RR 0,52, 95% CI 0.41-0.65) and the 70-74 year age group the lowest (RR = 0.23, 95% Cl 0.15-0.36). The rate ratios for the early (0-12 months) and late (13-24 months) interval cancers were similar (RR = 0.18, 95% Cl 0.15-0.22 and 0.20, 95% CI 0.17-0.24). There was a significantly lower interval cancer incidence in the prevalence round as compared with the incidence rounds. According to the detection method the episode sensitivity increased with age from 57% in the age group 40-49 years to 84% in the age group 70-74 years. The corresponding figures for the incidence method were 50% and 77%, respectively.
