Analysis of births occurring in Australia during 1976-9 showed that they followed a seven-day cycle, being concentrated on Tuesdays to Fridays and least numerous on Sundays, which had 26% fewer births than expected. Stillbirth and neonatal death rates were 17% and 29% higher respectively among babies born at weekends than among those born on weekdays. The incidence of low birth weight was also ...

abstract in order to investigate the freezing tolerance of field grown fennel (fueniculum vulgare mill) under controlled conditions, a factorial experiment based on completely randomized design was conducted with three replications in agricultural college, ferdowsi university of mashhad in 2004. treatments were two fennel ecotypes (khorasan and kerman), two planting dates (oct 8th and 29th ) an...

the life table parameters of macrosiphum rosae l. (hemiptera: aphididae) on five vermicompost-tea (tea-compost) concentrations (20, 40, 60, 80 and 100%) and control treatment (0%) on rosa hybrida l. were determined under laboratory conditions. there were significant differences among pre-imaginal period and adult longevity of the aphid on the five teacompost concentrations. the highest mortalit...

Growth rate was 35, 32 and 29 g/d, food consumption was 87, 99 and 69 g/d, FCR was 2.54, 3.18 and 2.38, total body fat was 12.7, 16.2 and 11.3%, abdominal fat was 2.91, 3.91 and 2.06%,-metabolisability of dietary energy was 75.4, 73.8 and 77.0%, and daily maintenance energy requirement was 860, 937 and 796 kJ/kg W' in lines W, F and E respectively. Average reproductive performance in terms of d...

The physiological and biomechanical changes that occur during pregnancy make accurate measurement of physical activity (PA) a challenge during this unique period. The Global Physical Activity Questionnaire (GPAQ) has been used extensively in low-to-middle income countries, but has never been validated in a pregnant population. In this longitudinal study, 95 pregnant women (mean age: 29.5±5.7 ye...

The effects of different patterns of alcohol administration on hepatocarcinogenesis induced by diethylnitrosamine (DEN) in male Wistar rats were assessed using a modified Ito's medium-term bioassay system. Carcinogenic potential was scored by comparing numbers and areas of glutathione S transferase placental form (GST-P)-positive foci. The activity of ornithine decarboxylase (ODC), the rate-lim...

BACKGROUND Among survivors of acute myocardial infarction, frequent and repetitive ventricular premature depolarizations (VPDs) detected on ambulatory monitoring contribute independently to the risk of all-cause mortality and sudden death. Apart from the beta-blockers, no antiarrhythmic drug has been reliably demonstrated to reduce mortality among patients with VPDs. A pilot study was undertake...

BACKGROUND We investigated the ergogenic effects of betaine (B) supplementation on strength and power performance. METHODS Twelve men (mean +/- SD age, 21 +/- 3 yr; mass, 79.1 +/- 10.7 kg) with a minimum of 3 months resistance training completed two 14-day experimental trials separated by a 14-day washout period, in a balanced, randomized, double-blind, repeated measures, crossover design. Pr...
