Blood pressure, heart rate, rate pressure product, heart rate variability, stroke volume, cardiac output, peripheral resistance, and cardiac contractility derived from impedance cardiography were obtained from 15 young and 15 old males during and after the Stroop task. The old group demonstrated significantly higher absolute heart rate, systolic and mean arterial pressure, peripheral resistance...
mara activates two membrane dependent mechanisms of resistance to different antibiotics, such as ciprofloxacin and tetracycline, including promotion of outflux and inhibition of influx of antibiotics. thus, mara causes multiple antibiotic resistance phenotype. the activation of these mechanisms needs overexpression of mara. this could happen through mutation in marr. thus, the aim of this study...
background: antimicrobial peptides with relative length (2-100 amino acids) and positive charge (pure charge (+9)-(+2)) are amphiphilic that isolated from a wide range of animals. recently, these peptides have been known as a part of innate immune response. nowadays, more than 500 antimicrobial peptides from animals have been reported. objectives: the aim of this study was to evaluate the anti-...
To determine the relative salt tolerance and/or resistance in seedlings of pistachio genotypes, four pot experimentswere conducted. In experiments 1 and 2, the effects of salinity on growth indices were studid. Experiments were donein the form of split plot based on RCBD. In each experiment, mainplots consisted of different electrical conductivitiesof irrigation water (ECiws). In experiment 1, ...
Salinity is one of the main obstacles to the successful production of agricultural products. Hormonal compounds such as salicylic acid (SA) as plant growth regulators can have different physiological and biochemical effects in plants under salt stress. In present research, the effects of different concentrations of sodium chloride (2, 6 and 10 dS/m) and foliar application of SA (0, 0.25 and ...
Drought as the most important abiotic stress has deleterious effects on plants. Developing drought tolerant varieties can help produce plants in a sustainable way. This study was conducted to identify drought tolerant and drought sensitive thyme species including Thymus vulgaris, T. vulgaris (origin: Spain), T. carmanicus, T. daenensis and T. kotschyanus and to study the mechanism used by them ...
In recent decade, establish and maintenance of turf grasses is faced with serious doubts due to reduction of precipitation and water resources. So, identification of drought-resistant native and rangeland species, and introducing them as turf grass not only is effective in reducing water consumption, but also help to preserve the genetic resources of the country. In order to evaluate the usabil...
BACKGROUND AND OBJECTIVES Fasting insulin concentrations are increasingly being used as a surrogate for insulin resistance and risk for type 2 diabetes (T2DM), although associations with adult outcomes are unclear. Our objective was to determine whether fasting insulin concentrations in childhood associate with later T2DM. METHODS Fasting insulin values were available from 2478 participants i...
background: the purpose of present study was to investigate whether sphingosine 1-phosphate (s1p) levels and its receptors gene expressions are correlated with myod and myogenin following resistance training. materials and methods: 24 eight-week-old male wistar rats (190-250 gr) were assigned randomly to a control (n = 12) or training (n = 12) group. rats climbed a resistance training ladder wi...
