the present experiment was undertaken to study the effect of different dosages of β-glucan on the growth, survival and physiological responses in juvenile striped catfish ( pangasianodon hypophthalmus ). over nine weeks of feeding fish with a diet containing 0, 0.5, 1 and 2% β-glucan (as control, g1, g2 and g3 group, respectively), some blood parameters such as serum lysozyme activity, total pr...

Background: Numerous evidences indicate that in some HIV-1 positive patients, the humoral and cellular immune responses are induced against HIV-1 proteins and this is inversely related to the progress of infection. Objective: The aim of this study was the evaluation of the Adenovectors containing HIV genes in induction of immune responses in mice. Methods: The HIV-1 genes including gag p24, rev...

Simultaneous suppression of multiple oncogenes is an attractive strategy to treat cancers. Herein we present a series of long double-stranded multiplex small interfering RNAs (multi-siRNAs) that is suitable for dual genes silencing through a sequence-specific RNA interference process without inducing significant immune responses. A gap feature structurally designed in either of the nucleotide s...

different medicinal plants have been used in animal and poultry nutrition in last decade. it seems that there are some potential to these medicinal plants to replace with common antibiotics. licorice root (glycyrrhiza glabra) is a medicinal plant that extensively was used in different studies. in the present study, the effect of dietary addition of licorice root on performance and blood energy ...

background: premature infants are among high-risk groups in community who need to be hospitalized at intensive care units for survival and receiving basic or special care. hospitalization at neonatal intensive care units (nicus) unsettles the family and leads to the separation of parents from their infants. this study aimed to determine the effects of maternal attachment behaviors on the behavi...

cortical spreading depression (csd) are associated with dramatic failure of brain ion homeostasis, efflux of excitatory amino acids from nerve cells, increased energy metabolism and changes in cerebral blood flow. there is strong clinical and experimental evidence to suggest that csd is involved in the mechanism of migraine, stroke, subarachnoid hemorrhage and traumatic brain injury. therefore,...

Cells in the rat barrel cortex exhibit stimulus-specific response properties. To understand the network mechanism of direction selectivity in response to facial whisker deflection, we examined direction selectivity of neuronal responses to single- and multi-whisker stimulations. In the case of regular-spiking units, i.e., putative excitatory cells, direction preferences were quite similar betwe...

Although many studies in neuroscience are based on comparing neuronal responses to single, isolated sensory or motor events, multiple events frequently occur in close temporal proximity in freely moving animals. This often obscures the precise temporal correlation between each event and the relevant brain activity. By simulating neuronal responses in multi-event tasks, we show that perievent ti...

Multi-biomarker approaches are used to assess ecosystem health and identify impacts of environmental stress on organisms. However, exploration of large datasets by environmental managers represents a major challenge for regulatory application of this tool. Several integrative tools were developed to summarize biomarker responses. The aim of the present paper is to update calculation of the "Int...
