BACKGROUND To evaluate the relationship between endometrial thickness on day of human chorionic gonadotrophin administration (hCG) and pregnancy outcome in a large number of consecutive in vitro fertilization and embryo transfer (IVF-ET) cycles. METHODS A retrospective cohort study including all patients who had IVF-ET from January 2003-December 2005 conducted at a tertiary center. RESULTS ...

the main objective of this study was to determine the effects of biofertilizers on quantity and quality of essential oil of basil essential oil content, geranial, caryophyllene, caryophyllene oxide and methyl chavicol in essential oil. the experiment was carried out as randomized complete blocks design with eight treatments and three replications at research field of agriculture company of ran ...

The concentration and the chemical composition of the essential oils obtained from different samples of Cymbopogon citratus were evaluated. Among the 12 samples investigated (11 dried leaf samples and fresh plant leaves), seven presented essential oil concentrations within the threshold established by the Brazilian legislation. The moisture content was also determined and the majority of the sa...

Background & Aim: The world production and consumption of essential oils and perfumes are increasing very fast. Lippia citriodora H.B.K. is an herbal species mainly used as a spice and medicinal plant. Endogenous levels as well exogenous application of plant growth regulators (PGR) could affect essential oil production and chemical compositions. Experimental: To study the effect of ex...

Lemon balm (Melissa officinalis L.), a member of Lamiaceae family, is an important medicinal plant that has many useful properties. Micronutrients are necessary in low dose for the growth and the development of plants. Present research was conducted to study the effects of micronutrients including manganese (Mn) and copper (Cu) on morpho-physiological traits and essential oil of lemon balm. Fie...
