background essential oils (eos) possess antibacterial properties and represent a natural source to treat infections and prevent food spoilage. their chemical composition might be affected by the environmental condition and the developmental growth stages of the plant. objectives the current study aimed to determine the variations in chemical compositions and antimicrobial activities of the eos ...

chamomile (matricaria chamomilla l.) is one of the most important medicinal plants in iran. the main objective of this study was to determine the effects of organic nutrients on the yield and oil content of chamomile. the experiment was conducted in the spring of 2010. the treatment groups consisted of vermicompost (0, 5, 10, 15 and 20 tons/ha) and the aminol forte sprays (no spraying or contro...

to evaluate the effects of nitrogen management at yellow budding stage on seed yield with using nitrogen nutrition index (ratio of nitrogen concentration in the plant to optimum concentration), of rapeseed farms in gorgan, an experiment was conducted as a nested model arranged in a complete randomized design (crd) in 2010. fifteen rapeseed fields were classified at three levels of management (o...

The ts3 temperature-sensitive mutant of Moloney murine leukemia virus has been reported to have a morphogenetic block in a late stage of the budding process. As evidence, previously published electron micrographs of cells maintained at the nonpermissive temperature (39 degrees C) revealed numerous budding virions on the cell surface. However, it appears now that these micrographs reflected budd...

BACKGROUND There is limited data on sexual maturation among girls with intellectual, sensory, or physical disabilities. OBJECTIVES The present cross-sectional study was conducted to assess the sexual maturation of girls with these disabilities in special schools. METHODS In this cross-sectional study, we evaluated the onset and progression of sexual maturation in 642 six to 18-year-old girl...

Phenylalanine amonia-lyase (PAL) is one of the most important enzymes that plays a key role in regulationof phenylpropanoid production in plants. It catalyzes the first step of the phenylpropanoid pathway in whichL-phenylalanine is deaminated to trans-cinnamic acid. This step is significant for metabolic engineering andhyper-expression of the major phenylpropanoid, methyl chav...

Squamous cell carcinoma (SCC) of the external auditory canal (EAC) is rare, usually presents at an advanced stage, and is a more aggressive tumor with poor prognosis. The University of Pittsburgh TNM staging system commonly used in prognostication is not perfect, and more accurate biomarkers predicting prognosis are needed. Tumor budding is an established negative prognostic factor at the invas...
