Background & aim: Recent researches have been done on effects of plant growth regulators (PGR) on growth and production of different crops whose results indicate the effectiveness of most of these hormones on qualitative and quantitative growth of herbs. The application of regulators and inhibitors of growth on herbs may, in addition to growth, also lead to secondary metabolites stimulation. Ja...

Secondary growth from vascular cambia results in radial, woody growth of stems. The innovation of secondary vascular development during plant evolution allowed the production of novel plant forms ranging from massive forest trees to flexible, woody lianas. We present examples of the extensive phylogenetic variation in secondary vascular growth and discuss current knowledge of genes that regulat...

Salinity is considered as one of the main limiting factors for growth and production of several agricultural crops all over the world. Also, salinity influences the growth and also synthesis of secondary metabolites of medicinal plants. Salvia viridis and Salvia spinosa are two aromatic species which belong to Salvia genus from Lamiaceae family. As the mechanisms of salt stress tolerance and al...

We have used both a rat orthotopic hepatocellular carcinoma model and a mouse allograft tumor model to study liver tumor ablation with nanosecond pulsed electric fields (nsPEF). We confirm that nsPEF treatment triggers apoptosis in rat liver tumor cells as indicated by the appearance of cleaved caspase 3 and 9 within two hours after treatment. Furthermore we provide evidence that nsPEF treatmen...

The growth of Salmonella typhimurium (ATCC 14028) on the surface of autoclaved ground chicken breast and thigh burgers incubated at constant temperatures from 8 to 48 degrees C in 2 degrees C increments was investigated and modeled. Growth curves at each temperature were fit to a two-phase linear primary model to determine lag time (lambda) and specific growth rate (mu). Growth of S. typhimuriu...

Secondary metabolites with low molecular weight and high economic, pharmaceutical and industrial values play an important role in protecting plants against biotic and abiotic stresses. Astragalus is a medicinal herb, rich in secondary metabolites. Selenium (Se) is an essential element for humans, animals, many bacteria, and a beneficial element for plants. The plants response to selenium is dep...

This paper looks beneath the surface of British sub-regional aggregate GVA growth over the period 1995-2004, by examining how the differing growth dynamics of the secondary and services sectors have influenced the overall regional growth process. A spatial econometric analysis is undertaken which tests regional secondary, services and aggregate real GVA per capita for absolute and conditional c...

Thickening of tree stems is the result of secondary growth, accomplished by the meristematic activity of the vascular cambium. Secondary growth of the stem entails developmental cascades resulting in the formation of secondary phloem outwards and secondary xylem (i.e., wood) inwards of the stem. Signaling and transcriptional reprogramming by the phytohormone ethylene modifies cambial growth and...
