Background: Ferulago angulata is an important medicinal plant and endemic to Iran which is an endangered Plant. Objective: The aim of this study was to achieve an efficient method for propagation of this plant and evaluation of essential oil content and composition in habitat. Metthods: Essential oils were extracted by hydrodistillation using Clevenger-type apparatus and its composition was ...

Narcissus is one of the very popular flowers among Iranians. This flower has a short life. To investigate the increasing of vase life of cut Narcissus, sour orange fruit extract in concentrations of 2.5, 4, 5.5 and 7 ml L-1 and sucrose in concentrations of 3, 4, 5 and 6% were used. In addition, distilled water was used as a control treatment. In this experiment, characters of vase life and perc...

Adverse early life experience is a known risk factor for psychiatric disorders. It is also known that stress influences food preference. We were interested in exploring whether the choice of diet following early life stress exerts long-lasting molecular changes in the brain, particularly the hippocampus, a region critically involved in stress regulation and behavioral outcomes. Here, we examine...

The heat inactivation of Lactococcus lactis was studied by determination of cell counts, and by FT-IR spectroscopy recording the average structure of cell proteins. Cell counts were measured after incubation milk buffer or milk buffer with 1. 5 M sucrose, and FT-IR spectra were recorded in (2)H(2)O or (2)H(2)O with 1. 5 M sucrose in the range of 6-75 degrees Celsius. Sucrose protected L. lactis...

Phosphorus (P) is considered an elementary mineral nutrient for plants. Nevertheless, excessive or deficit supply to the crop may cause negative changes at physiological level. Plants were cultivated in pots a growth chamber under increasing P concentration (P1 (0.5 mmol/L (control treatment)), P2 (1 mmol/L); P3 (2 P4 (4 P5 (6 mmol/L), and P6 (8 mmol/L)) solution 40 days. At end of experimental...

T cell dysfunction that occurs after surgery or trauma is associated with a poor clinical outcome. We describe that myeloid suppressor cells expressing CD11b(+)/Gr-1(+) markers invade the spleen after traumatic stress and suppress T cell function through the production of arginase 1. We created a consistent model of traumatic stress in C57BL/6 mice to perform this work. A significant number of ...

The most important quality for muskmelon (Cucumis melo L.) is their sweetness which is closely related to the soluble sugars content. Leaves are the main photosynthetic organs in plants and thus the source of sugar accumulation in fruits since sugars are translocated from leaves to fruits. The effects of grafting muskmelon on two different inter-specific (Cucurbita maxima×C. moschata) rootstock...

Summer fruit drop (June drop) is one of the main reasons for low yield in some citrus varieties in northern Iran. Recognition of physiological changes in fruit abscission zone (calyx) and application of suitable treatments would reduce or control abscission. Hence, the changes of auxin, cellulose, and polygalacturonase in calyx of Thomson navel fruitlets were measured and their relations with a...
