We have obtained deep images in the near-infrared J and K filters of four fields in the Sculptor Group spiral galaxy NGC 55 with the ESO VLT and ISAAC camera. For 40 long-period Cepheid variables in these fields which were Based on observations obtained with the ESO VLT for Large Programme 171.D-0004

During the study on rust mycobiota of Central Alborz, several rust infected specimens belonging to Salicaceae family including Populus and Salix species were investigated. Populus nigra, P. euphratica, Saix alba and S. excelsa were infected by various Melampsora species. Uredinial (II) and telial (III) stages of rust were present on infected plants. According to morphological characters, five f...

Male and female leaves and fruits of eleven different taxons of Iranian conifers (Cupressus sempervirens var. horizontalis, C. sempervirens var. sempervirens, C. sempervirens cv. Cereifeormis, Juniperus communis subsp. hemisphaerica, J. excelsa subsp. excelsa, J. excelsa subsp. polycarpos, J. foetidissima, J. oblonga, J. sabina, Platycladus orientalis and Taxus baccata) were collected from diff...

The essential oils of branchlets and fruits of Juniperus excelsa subsp. excelsa and Juniperus excelsa subsp. polycarpos were examined for their antioxidant activity. The compositions of the essential oils were studied by GC and GC-MS. To evaluation the antioxidants activity of the volatile oils, pure components and positive controls at different concentrations, thin-layer chromatography (TLC) s...

There is growing interest in flavonoids for their wide array of biological actions. In neurodegenerative disorders these naturally occurring polyphenolic compounds, are known to inhibit proinflammatory mediators such as in TNF–? and IL-6 in lipopolysaccharide (LPS) stimulated neuronal degeneration, which are associated with Alzheimer’s and Parkinson’s disease. Recent studies on flavonoids have ...
