Background: In China, mosquito-borne diseases are most common in the sub-tropical area of Yunnan province. The objective of this study was to examine behaviors related to mosquito-borne diseases in different ethnic minority groups and different socioeconomic groups of people living in this region. Methods: A stratified two-stage cluster sampling technique with probability proportional to size w...
PURPOSE This study was conducted to compare the paternal rearing behavior and rearing stress level between fathers with a preschooler and fathers with school children so that it can be utilized as a basic source for developing parental rearing education programs. METHODS A descriptive comparative method was conducted to identify the paternal rearing behavior and paternal rearing stress. Respo...
The objective of this study was to investigate the effect of the rearing conditions during the fattening period of Iberian pigs on the acceptance of the dry-cured hams, and to research into the relationship between acceptance and sensory characteristics, chemical composition and physical-chemical parameters. The duration of the fattening period in Montanera (outdoor system based on acorns and g...
Embryos of Xenopus laevis reared in media with various low (less than or equal to 10(-5) M) magnesium ion concentrations will exhibit differing degrees of a potentially lethal magnesium starvation syndrome depending on the ion concentration and rearing temperature. The higher the rearing temperature or the lower the magnesium ion content of the medium the more severely the syndrome will be expr...
OBJECTIVE To assess the influence of infant rearing on the behavior of depressed adult female Macaca fascicularis and the influence of depressed infant-rearing adult female Macaca fascicularis on their infants in a free enclosure environment. METHODS Here, 20 depressed subjects and then 20 healthy subjects were randomly selected from a total population of 1007 adult female Macaca fascicularis...
Neonatal cholera is a extremely rare in neonate. Colostrum may offer potent protection among breast fed neonates mediated by specific immunoglobulin IgA. Occurrence of cholera in a new born reflects the poor hygienic condition of the family and bad child rearing practice. As rehydration therapy and antibiotics is the main stay of treatment of this particular condition, the broader perspective i...
Thus far, the developmental plasticity of the visual system has been studied by altering or reducing visual experience. Here, we investigated whether a complex sensory-motor stimulation, provided by rearing animals in an enriched environment, affects visual system development. We found that raising mice in this condition causes an earlier eye opening, a precocious development of visual acuity, ...
1. The effect of biotin supplementation of low-biotin practical diets during rearing and laying stages on performance was studied in White Leghorn-type laying hens. 2. Biotin supplementation during rearing did not have any apparent effect on the condition of the bird at point-of-lay or on subsequent laying performance. 3. Biotin supplementation during lay did not have any beneficial effect upon...
Previous investigations have shown that REM sleep deprived (REM SD) rats display an enhanced response to dopamine agonists. This action seems to be mediated through a supersensitivity of dopamine post-synaptic receptors. Accordingly, REM SD was performed on rats with an experimental model of Parkinson's disease. The animals were bilaterally lesioned in the nigrostriatal pathway through a stereo...
Significance of stocking density in broiler production i.e. production performance, vitality and health condition of chickens, was established at the beginning of development of industrial poultry production. However, considering intensive development of selection work and creation of more productive genotypes which, at the same time, were more demanding in regard to rearing conditions, the cur...
