The relationship between epithelial cell production and growth rate was investigated in Hydra attenuata under different feeding regimes. The increase of epithelial cell number was compared to the duration of the epithelial cell cycle using standard methods of cell cycle analysis. The results indicate that cell cycle changes accompanying changes in feeding regime are not sufficient to explain th...
Abstract Background & Aims : Optimal entral feeding methods in preterm infants have not been well defined. Controversy exists regarding when feedings should be started, whether minimal entral feedings should be used routinely in small preterm infants, and how fast to advance entral feedings. Preterm infants can exhibit delayed gastric emptying and often have feeding residuals. So, entral fe...
Effect of different feeding levels on water quality, growth performance, survival rate and body composition of Pacific white shrimp Litopenaeus vannamei post larvae were studied in zero water exchange system. Shrimp post larvae with mean weight of 74.46± 6.17 mg were fed for 32 days in 300L fiberglass tanks containing 130L water at density of 1 post larvae L-1. There were five treatments includ...
employees always concern about losing their job , or in other word , losing their income resources. for this purpose, every government requires strong system for covering these concerns. the unemployment insurance (ui) program’s can be used for achieving this goal. in this thesis, we price ui based on the insurance history of employee and the duration of being unemployed. we use the weibull dis...
the study of air infiltration into the buildings is important from several perspectives that may be noted to energy and design of hvac systems, indoor air quality and thermal comfort and design of smoke control systems. given the importance of this issue, an experimental and numerical study of air infiltration through conventional doors and windows has been explored in iran. to this end, at fir...
Effect of Iron Oxide Feeding Rate and Hot Metal Temperature on Dephosphorization Rate in Torpedo Car
Dense beds of the suspension-feeding brittlestar Ophiothrix fragilis are common in European waters. Their potential importance in benthic±pelagic coupling has been highlighted, but little is known about the feeding dynamics of this species. Encounter-rate models provide a potential mechanism for the estimation of feeding rates on suspended material of varying sizes. This work investigates facto...
BACKGROUND In traumatic brain injury (TBI), the appropriate timing and route of feeding, and the efficacy of immune-enhancing formulae have not been well established. We performed this meta-analysis aiming to compare the effects of different nutritional support modalities on clinical outcomes of TBI patients. METHODS We systematically searched Pubmed, Embase, and the Cochrane Library until Oc...
1. The rate of [C]leucine incorporation into the protein of frog pepsinogenic cells was measured in both fasted and fed animals. The incorporation rate increases after feeding, becoming maximal after z h. 2. In the oesophagi of fasted frogs, only monoribosomes and dimers are present. The absence of polyribosomes is not due to autolysis in the homogenate. After feeding, heavy polyriboaomal aggre...
Background and Aim: Use of pacifiers by young infants has been recognized as one of the factors that interfere with the establishment of successful breast-feeding. Our aim was to find out if pacifier-use results in early termination of breast-feeding. Materials and Methods: A historical cohort study was done on mother-infant pairs visiting health centers for check-ups, routine vaccinations or ...
