The cytosolic phospholipase A2α(cPLA2α) is one of the potential targets for anti-inflammatory drugs, since this enzyme plays a key role in the inflammation processes seen in health disorders, like asthma, allergic reactions, arthritis and neuronal diseases. In this study, cPLA2α inhibition by 43 methanol extracts from medicinal plants rich in polyphenols was determined. The eight most active ex...

The principal objective of this study was to investigate the effect of household processing, including washing and cooking on pesticide residue levels in various food samples. For this study, 31 food materials were selected and 44 pesticide residues were monitored using the “quick, easy, cheap, effective, rugged, and safe” QuEChERS extraction-based and liquid chromatographyetandem mass spectrom...

The aim of this investigation was to determine the content of total phenolics, antioxidant activity and cytotoxicity of methanol extracts from the aerial parts of 11 Korean medicinal salad plants. The highest total phenolic content of the methanol extracts was found in Aster scaber (17.1 mg 100 g(-1)), followed by Ixeris dentate (16.4 mg 100 g(-1)), Aster yomena (12.0 mg 100 g(-1)) and Sedum sa...

Prophylactic treatment constitutes an important aspect of migraine management and includes avoidance of trigger factors and life style advice followed by consideration of medications. The drugs of first choice are beta-blockers, flunarizine, topiramate, valproate and amitriptyline. Drugs of second choice with less efficacy and evidence are venlafaxine, gabapentin, naproxen, butterbur root, ribo...

In early dental plaque formation, oral primary colonizers such as Streptococcus mutans, Streptococcus sanguis and Actinomyces viscosus are initially attached to the pellicle-coated tooth surface to form a biofilm. The study aimed to determine the efficacy of macelignan, isolated from nutmeg (Myristica fragrans Houtt.), in removing each single oral primary biofilm in vitro on a polystyrene 96-we...

The Alaskan swallowtail butterfly, Papilio machaon aliaska (Lepidoptera: Papilionidae), uses three plant species as host plants. Cnidium cnidiifolium (Turcz.) Schischk. belongs to the family Apiaceae, the ancestral host-plant family of the P. machaon group. Artemisia arctica Less. and Petasites frigidus (L.) Franch, in contrast, belong to the distantly related Asteraceae family and were coloniz...
