abstract        background and objective: peroxidases catalyze protein oxidation and lipid peroxidation. the activity of these enzymes in nerve cells is involved in causing disorders such as alzheimer's and parkinson's disease. this study investigated the effect of citrus aurantium, foeniculum vulgare and rosmarinus officinalis essential oils on activity of peroxidase enzyme.       me...

background: alternaria alternata (aa) is a fungus that has wide range of plant host and can cause diseases in humans and produces a number of mycotoxins. exposure to high numbers of aa spores can trigger severe asthma exacerbations. resistance to antifungal drug has been shown in this species. trachyspermum copticum (ajowan) is an annual herbaceous essential oil )eo) bearing plant . the ripenin...

objective(s):various species of genus trigonella are important from medical and culinary points of view. the essential oil of trigonella torbatejamensis ranjbar as an endemic plant in iran has not been studied previously. the essential oil of this plant was analyzed by different methods for identification of its components. materials and methods: the essential oil composition of aerial parts of...

background: essential oils, as secondary plant compounds, present a safer alternative to conventional insecticides in insect control programs. so five essential oils including eucalyptus, mint, yarrow, oregano and rosemary oils were evaluated against the brown-banded cockroach supella longipalpa . methods : evaluation was done against the 3 rd and 4 th instar nymphs using three bioassay methods...

conclusions based on these observations, wide variation is detected in the chemical composition of the oil obtained from the same plant in different seasons. materials and methods the oil was extracted by hydro-distillation from two samples collected in different seasons, and analyzed by gc-fid and gc-ms. results in total, 18 and 20 components were identified and quantified in the oil of summer...

the chemical composition of the essential oil obtained from the aerial parts of laurus nobilis l. has been examined by gas chromatography (gc) and gc- mass spectrometery (ms). the main components of the oil were identified. 1,8-cineole was the major component in the oil together with b-terpinyl acetate, terpinene-4-ol, a-pinene, b-pinene, p-cymene, linalool and terpinene-4-ylacetate. the essent...

Hypothesis Implication for health policy/practice/research/medical education: The combination of metformin and ginger extract may be more effective for the control of diabetes and may have additive protective efficacy on diabetic nephropathy. N ephropathy of the diabetes is one of the most important complications of this illness. Recently, much attention has been made toward the possible kidney...

UNLABELLED Ginger has been shown to exert anti-inflammatory effects in rodents, but its effect on human muscle pain is uncertain. Heat treatment of ginger has been suggested to enhance its hypoalgesic effects. The purpose of this study was to examine the effects of 11 days of raw (study 1) and heat-treated (study 2) ginger supplementation on muscle pain. Study 1 and 2 were identical double-blin...

ABSTRACT The genetic diversity of Ralstonia solanacearum strains isolated from ginger (Zingiber officinale) growing on the island of Hawaii was determined by analysis of amplified fragment length polymorphisms (AFLPs). Initially 28 strains of R. solanacearum collected from five host plant species worldwide were analyzed by AFLP. A second analysis was conducted on 55 R. solanacearum strains coll...
