the hawthorn fruits have been used as food and medicine for centuries. in the present study, pulp and seed extract of crataegus elbursensis rech. f. fruits belonging to the family rosaceae and native of northern part of iran were evaluated for the polyphenol contents, antiradical, antioxidant, and antibacterial activities. the total phenolic, flavonoid, and anthocyanin contents of methanolic pu...

sumac (rhus coriaria l.) is used as an herbal remedy in traditional medicine. the aim of this study was to determine the effects of sumac (rhus coriaria l.) on serum glycemic status, apolipoprotein (apo) b, apoa-i and total antioxidant capacity (tac) in type 2 diabetic patients. this double blind randomized controlled clinical trial was conducted on 41 type 2 diabetic volunteers randomly assign...

screening of microorganisms for the production of novel antibiotics has been intensivelypursued for many years by scientists. actinomycetes have the capability to synthesize manydifferent antibiotics. a total of 69 actinomycete isolates were recovered from soil samplescollected from alborz province. selected colonies (rough, chalky) of actinomycetes werepurified. all screened isolates were iden...

We previously demonstrated that the tergotrochanteral muscle (TTM) of Drosophila is innervated by unique synapses that possess a small readily releasable/recycling vesicle population (active zone population), but not the larger reserve vesicle population observed at other neuromuscular junctions in this animal. Using light and electron microscopic techniques and intracellular recording from the...

The cellular mechanisms involved in the formation of the glutamatergic postsynaptic density (PSD) are mainly unknown. Previous studies have indicated that PSD assembly may occur in situ by a gradual recruitment of postsynaptic molecules, whereas others have suggested that the PSD may be assembled from modular transport packets assembled elsewhere. Here we used cultured hippocampal neurons and l...

Background: Dental caries is one of the most common oral diseases in pre-school children. Several factors can affect caries process. Aim of this study was comparison of some of the chemical properties of saliva such as total antioxidant capacity, total protein, pH, nitric oxide level in caries free (CF), and caries active (CA) children.<...

objective: the inoculation of substrates with arbuscular mycorrhizal fungi (amf) is one of the most important effective strategies applied and one of the aims of sustainable agriculture. methods: this experiment was conducted to evaluate the effects of amf inoculation (0, 2.5, and 5 w/w) on morpho-physiological traits such as flower and root dry weight, water-use efficiency and antioxidant capa...

background &amp; aim: fruits from the jujube plant (ziziphus jujuba) possess health-promoting effects and medicinal properties. jujube has a long history of usage as a remedy in iranian traditional medicine and is recommended for the treatment of some diseases. this study investigated the variations in antioxidant capacities (aox), total phenol (tph), total flavonoid (tf) and total anthocyanin ...

background and objectives: periodontal disease is a chronic disorder with a high prevalence. there are few studies about the role of diet in prevention and treatment of periodontal disease. the aim of this study was to evaluate the effect of consumption of chicory leaf extract in adjunct with non-surgical periodontal therapies on serum antioxidant and lipid status. materials and methods: this s...
