BACKGROUND Sporadic Alzheimer's Disease (SAD) is caused by genetic risk factors, aging and oxidative stresses. The herbal extract of Rosa canina (R. canina), Tanacetum vulgare (T. vulgare) and Urtica dioica (U. dioica) has a beneficial role in aging, as an anti-inflammatory and anti-oxidative agent. In this study, the neuroprotective effects of this herbal extract in the rat model of SAD was in...
Non-symbiotic (nsHb) and truncated (tHb) hemoglobins (Hbs) have been detected in a variety of land plants. The evolution of land plant nsHbs and tHbs at the protein level is well documented; however, little is known about the evolution of genes coding for these proteins. For example, the variability of the land plant nshb and thb genes is not known. Here, we report the variability of the nshb a...
The potential antisenescence effect of eight synthetic urea compounds was investigated in excised barley (Hordeum vulgare L.) leaves which were induced to senesce by incubation in complete darkness. The compounds having uncyclic ureido group showed higher chlorophyll retention activity than those with cyclic ureido group. Compounds 1, 6 and 4PU had long-term protecting effects on chlorophyll de...
مطالعات کاریولوژیک، به منظور اصلاح گیاهان و بررسی روابط تکاملی آن ها از اهمیت ویژه ای برخودار است. تغییرات کروموزومی نقش مهمی در سازش گیاهان به شرایط مختلف محیطی و گونه زایی دارد. زیره سبز (cuminum cyminum) و رازیانهfoeniculum vulgare) ) از مهم ترین گیاهان دارویی تیره ی چتریان (apiaceae) به شمار می روند. در این پژوهش، مریستم نوک ریشه، حاصل از بذرهای جوانه دار شده جمعیت-های زیره سبز (c. cyminum)...
Marrubium vulgare L. is a spont aneous plant of great medicinal value due to the presence secondary metabolites. Our work aims study physicochemical and phytochemical profile this species. The results analyzes showed that has sug ar content 5.91%, lipid 4.12%, total fiber o f 6.42%, water 42. 42%, an ash 17.76%, solids 2.5 degrees Brix, electrical conductivity 4.06 mS/cm 2 pH 4.8. Regarding var...
Nitrate reductase activity in barley (Hordeum vulgare L. cv. Himalaya) aleurone layers has been determined in the intact tissue, using two different methods. The first method measures the rate of appearance of H(2) (18)O produced during the reduction of KN(18)O(3). The second assay measures excreted nitrite resulting from nitrate reduction under anaerobic conditions. Nitrite production in this ...
Background and purpose: There are few treatment options available for treatment of toxoplasmosis and effective drugs have serious toxic effects. In this study, the in vivo and in vitro anti-toxoplasma activities of Heracleum persicum and Foeniculum vulgare fruits essential oils were investigated. Materials and methods: In vitro, Vero cells were incubated with different concentrations of essent...
Background and Objective: Apoptosis plays a key role in the pathogenesis of a variety of cardiovascular diseases, especially cardiac failure. Therefore, the purpose of this study was investigating the effect of Origanum vulgare extract supplementation with and without exercise training on p53 and cytochrome c gene expression in myocardium of male rats. Materials and Methods: Nineteen three-...
W hat can go wrong after an egg is fertilized by sperm from a different species? One of the most intriguing outcomes to the chromosome biologist is uniparental genome elimination. In this phenomenon, one of the parental chromosome sets is completely lost during embryonic cell divisions, creating sterile haploid offspring (1). Uniparental genome elimination occurs in diverse taxa, including seve...
