-The disease dynamics and progression of HIV-MTCT over a period of time and disease transmission and susceptible simulation model (DTSM-MODEL) were computed by different reproduction numbers for each time interval with set of fixed values of the parameters. As per the model, study found that placental absorption ,prolonged breast feeding and absence of ARV at the onset of birth or delivery, aft...

The seasonal and interannual variability of feeding in 15 species benthic marine suspension feeder was studied over 8 yr at Ryder Bay, Antarctica. Feeding strongly bryozoans, gorgonians, polychaetes, dendrochirote holothurians. winter non-feeding period longest the holothurians shortest bryozoans. Bryozoans started late very low chlorophyll concentrations, often when surface fast-ice still pres...

We examined the effects of oral glucosamine hydrochloride (GlcN), N-acetyl-D-glucosamine (GlcNAc) and d-glucose (Glc) administration on plasma total free amino acid (PFAA) concentrations in dogs. The PFAA concentrations increased in the control group and the GlcNAc group at one hour after feeding, and each amino acid concentration increased. On the other hand, in the GlcN group and the Glc grou...

the purposes of this study were to evaluate of ovarian and insulin dynamics in dairy cows fed omega-3 fatty acid source. ten holstein multiparous cows were selected and after adaptation period given diets containing palm oil (control) and fish oil (treatment) from day -40 to 60 after calving. the study carried to show the effect of omega-3 fatty acids on insulin resistance. glucose tolerance te...

Concentrations of HIV-1 RNA and DNA in mucosal compartments influence the risk of sexual transmission and mother-to-child transmission of HIV-1. Breast milk production is physiologically regulated such that supply is a function of infant demand, but whether demand also influences HIV-1 dynamics in breast milk is unknown. We tested whether minor and major changes in feeding frequency influence b...

this paper works on the concept of flatness and its practical application for the design of an optimal transient controller in a synchronous machine. the feedback linearization scheme of interest requires the generation of a flat output from which the feedback control law can easily be designed. thus the computation of the flat output for reduced order model of the synchronous machine with simp...

BACKGROUND Vertebrate bloodfeeding is a critical component of a mosquito's ability to transmit pathogens that cause diseases such as malaria, dengue fever and viral encephalitis. Due to degradation by the digestive process, current methods to identify mosquito bloodmeal sources are only useful for approximately 36 hours post-feeding. A critical need exists for technologies to extend this window...

The article presents the results of studying dependence fattening qualities pigs on type feeding during rearing and its change these two periods. It is proved that dynamics pig growth depended changes. In first third experiment, live weight piglets with liquid was added more intensively. second experiment (70–120 days) animals same were characterized by intensive compared to analogues in which ...

BACKGROUND Hypernatremic dehydration in neonates is a potentially devastating condition. Recent reports have identified breast-feeding malnutrition as a key factor in its pathophysiology. METHODS Using a theoretical framework for breast-feeding kinetics, a retrospective chart review of all neonates less than 28 days of age who were seen at either British Columbia's Children's Hospital or the ...
