Background: Given the concerns about the use of chemical preservatives in food, the consumers and producers have been interested in natural alternatives, such as plant essential oils and extracts. Since there are limited studies about the effect of saffron (Crocus sativus L.) on the behavior of foodborne pathogens in food models, this study aimed to determine the inhibitory effect of aqueous ex...

objective(s) ziziphora clinopodioides lam. is a plant widely used in iranian traditional medicine for gastrointestinal disorders. several reports have demonstrated antibacterial (helicobacteria pylori), antioxidant and anti­inflammatory properties of z. clinopodioides. the aim of this study was to investigate the effects of aqueous- ethanol extract of z. clinopodioides on rat’s gastric acid out...

In 1932 Kettle1 reported that where quartz particles are coated with iron their fibrogenic action is inhibited. Although initially unsuccessful, Gardner was able to confirm this inhibitory action in 1938. More recently Vorwald4 also described the inhibitory action of iron on experimental silicosis in guinea pigs. Finely divided metallic aluminum powder according to Denny et al.,#{176} and alumi...

Aspirin and other non-steroidal anti-inflammatory drugs reduce the risk of cancer due to their anti-proliferative and apoptotic effects, which are the important mechanisms for their anti-tumor activity. Here, the effect of aspirin on human cholangiocarcinoma cells (KKU-214) and the underlying mechanisms of its action were explored. Cell proliferation was measured by sulforhodamine B (SRB) assay...

The ability to inhibit the processing of irrelevant information declines as adults age (Hasher & Zacks, 1988; Lustig, Hasher and Tonev, 2006; Mayr, 2001). However, previous research investigating inhibitory control in older adults has not evaluated the extent to which irrelevant information is processed and later recognized. Using a dual task paradigm with young adults, Dewald, Sinnett, and Dou...

recently, the effects of antimicrobial activity of silver nanoparticles was considered by researcher because of bacterial resistance to antimicrobial agents in chemical.the aim of this study was to evaluate the antimicrobial activity of the gold nanoparticles on escherichia coli. gold nanoparticles are chemically synthesized. standard strain of e. coli was cultured in a nutrient broth. minimum ...

A series of experiments were conducted to examine the inhibitory effect of a visual distracter on saccadic eye movements. Participants were presented with a sequence of two critical displays. In one display a red target was presented together with a green distracter. This was followed by a display with a new red target presented in isolation at one of three locations with respect to the previou...

In two experiments, f3-carotene applied to mice initiated with 7,12-dimethylbenz[a]anthracene (DMBA), concomitantly with croton resin and croton oil, increased tumor incidence by 58 and 29%. In the same experiments, retinyl acetate reduced tumor incidence by 76 and 29%. Retinol in one experiment reduced the number of papillomas by 75%. f3-lonone, squalene, and isoprene had little or no effect o...

We investigated the mechanism for isolated agranulocytosis and marrow pure white cell aplasia in an elderly man receiving 0.5 to 1 .0 g per day of chlorpropamide (Chl) without other toxic drug exposure or overt systemic illness. Patient marrow revealed an absence of recognizable granulocytic precursors; megakaryocytes and erythroid precursors were normal. The WBC count was 1800/ mm3 on admissio...
