In the UK, the Norway lobster (Nephrops norvegicus) supports its most important shellfish fishery. Nephrops are sold either whole, or as "tails-only" for the scampi trade. In the "tailing" process, the "head" (cephalothorax) is discarded as waste. A smaller crustacean species, the Antarctic krill Euphasia superba, represents an economically valuable industry, as its extractable oil is sold as a...

Achillea millefolium L. is a member of the Asteraceae family and has been used in folk medicine in many countries. In this study, 19 compounds in A. millefolium essential oil (AM-EO) have been identified; the major components are artemisia ketone (14.92%), camphor (11.64%), linalyl acetate (11.51%) and 1,8-cineole (10.15%). AM-EO can suppress the inflammatory responses of lipopolysaccharides (L...

The mitogen-activated protein kinase (MAPK) family, including extracellular signal-regulated kinase (ERK)1/2, c-Jun N-terminal kinase (JNK)1/2 and p38 MAPK, is known to be activated by ultraviolet (UV) radiation in melanocytes to regulate melanin production. Reactive oxygen species (ROS) play important roles in the pathway of ERK and JNK activation. It has been established that the essential oi...

Liver disease is a worldwide problem. It represents one of the main causes of morbidity and mortality in humans. Achillea biebersteinii is used as herbal remedy for various ailments including liver diseases. But the scientific basis for its medicinal use remains unknown. Thus, this research was undertaken to evaluate the efficiency of A. biebersteinii essential oil (ABEO) (0.2 mL/kg) in the ame...

abstract essential oils (eos) of achillea eriophora, extracted by hydrodistillation and their constituents were analyzed by gas chromatograph (gc) and gc/mass spectrometry using retention indices and fragmentation patterns. the antibacterial effects of the eo was assessed on several food-borne pathogens, namely staphylococcus aureus, bacillus cereus, escherichia coli o157:h7, salmonella enterit...

BACKGROUND & OBJECTIVES Leishmaniasis is a parasitic disease transmitted by sand flies. Many investigations are performed to find an effective and safe treatment for leishmaniasis. In this study, we evaluated the efficacy of herbal extracts of Thymus vulgaris (Thyme) and Achillea millefolium (Yarrow), propolis hydroalcoholic extract and systemic glucantime against cutaneous leishmaniasis in Bal...

The species of genus Achillea, particularly those belonging to the Achillea millefolium group have received a lot of attention so far, due to their use in traditional medicine. Among the numerous chemical compounds isolated from the A. millefolium species, the sesquiterpene lactones are usually one of the major constituents (Seaman, 1982). Continuing our chemotaxonomic examination of Bulgarian ...

Yarrow (Achillea spp.) belonging to the family of Asteraceae with useful properties, such as anti-diaphoretic, anti-hemorrhagic, anti-inflammation, anti-biotic, anti-fungal, anti-bacterial, Carminative and anti-oxidant effects. The present investigation assessed the morphological diversity of Achillea aucheri, which is indigenous plant from Damavand mountain of Iran. The samples were collected ...

Background and objectives: The majority of the Achillea spp. are used as medicinal plants with therapeutic applications worldwide. Achillea aucheri was selected in our study to assess its essential oil chemical composition along with antimicrobial evaluation. Methods: The essential oil of A. aucheri achieved ...

Techniques for the enumeration and the determination of the potential activity of disturbed sediment mixed populations at control sites and sites within the Athabasca oil sands formation were applied to August and December samples. These techniques included the determination of general heterotrophic potential for the assimilation and respiration of glutamate, which indicated no oil sand-related...
