background: although heterotopic gestation is common in assisted reproductive techniques, it is very rare in natural conception and clomiphene induced pregnancy. diagnosis and appropriate intervention of heterotopic pregnancy requires a high index of suspicious. case: in this paper a case of heterotopic pregnancy in a 30-year old woman with hemoperitoneum from ruptured tubal pregnancy with live...

this prospective longitudinal study deals with the associations between digital disorders and reproduction indices in dairy cattle on a farm in the vicinity of tehran. it was carried out on 225 postparturient holstein heifers. the evaluation of lameness due to digital disorders on postpartum period of heifers were done and after diagnosis of lameness (based on a 5 points lameness scoring system...

OBJECTIVE Based on emerging preclinical findings suggesting that paternal smoking at conception may be a risk for ADHD in the offspring, we investigated whether a similar effect can be observed in humans. METHOD We analyzed data from an opportunistic dataset of girl probands with ( N = 140) and without ( N = 122) ADHD with available information on paternal smoking at conception. Data were ana...

OBJECTIVES To assess the risk of autism spectrum disorders (ASD) in children born after assisted conception compared with children born after natural conception. DESIGN Population-based follow-up study. SETTING All children born alive in Denmark 1995-2003. PARTICIPANTS 588,967 children born in Denmark from January 1995 to December 2003. Assisted conception was defined as in vitro fertilis...

The objective of this experiment was to test in vitro embryo production (IVP) as a tool to estimate fertility performance in zebu bulls using Bayesian inference statistics. Oocytes were matured and fertilized in vitro using sperm cells from three different Zebu bulls (V, T, and G). The three bulls presented similar results with regard to pronuclear formation and blastocyst formation rates. Howe...

The aim of this work was to evaluate the efficiency of the intrauterine insemination (IUI) in swine, considering the conception rate, farrowing rate, litter size (alive born pigs). For the IUI, the females had been insemination at 24 and 48 hours after the estrus detection, and the inseminating doses of 500 million, 1 billion, 1.5 billion and 2 billion spermatozoa in 20 mL extender had been use...

Body condition score (BCS), energy content (EC), cumulative effective energy balance (CEEB), and blood serum concentrations of glucose, beta-hydroxybutyrate (BHBA), and nonesterified fatty acids (NEFA) were measured throughout first lactation in 497 Holstein cows raised on a large commercial farm in northern Greece. All these traits are considered to be indicators of a cow's energy balance. An ...

the aim of this study was to compare the efficiency of five synchronization protocols, economically, in holstein cows during heat stress. this experiment was conducted at a commercial dairy farm in summer 2015 (temperature humidity index 73–81). five hundred holstein dairy cows with ˃25 kg/d milk yield were randomly assigned to five experimental groups: 1) ovsynch; 2) presynch-ovsynch; 3) doubl...

this experiment was conducted to evaluate reproductive indices and provide appropriate solutions to improve the reproductive efficiency of dairy cattle in kermanshah province. with reference to forty-eight dairy industrial herds available at different cities of the province, a questionnaire containing quantitative measures were completed to assessing the reproductive parameters of 5397 dairy co...
