• Insecticidal activity of 47 macroalgae mostly from Mediterranean Sea was examined. Cholinesterase and tyrosinase inhibitory effect the alga extracts investigated. D. dichotoma var. intricata only one exhibiting BChE inhibition over 50%. by four diterpenes in DDI investigated silico . The their metabolites might be new sources novel insecticides. Ethanolic prepared forty-seven species collecte...

Microscopic algae are tougher than you might think. Some can even survive the extreme cold. In this article, we describe one of coolest all, Antarctic green alga called Chlamydomonas sp. UWO241. This one-celled super-organism lives deep in frigid waters a remote and permanently ice-covered lake Antarctica. How does little thrive such barren unwelcoming place? Well, dive into article to learn ho...

Prokaryotic autotrophs have a key role in maintaining the sustainability of nature. Their secondary metabolites and stored chemicals wide utility human life. Cyanophytes, primitive producers, can become necessity modern world as they enormous unexplored features. Candida albicans, an opportunistic pathogen having multidrug resistance, fallout health concerns animal hosts. This study focused on ...

BACKGROUND Spirulina is a commercial alga well known to contain various antioxidants, especially phycocyanin. Apart from being sold as a nutraceutical, Spirulina is incorporated as a functional ingredient in food products and beverages. Most of the previous reports on antioxidant activity of Spirulina were based on chemical rather than cell-based assays. The primary objective of this study was ...

Biofilms of the bacterium Pseudoalteromonas induce metamorphosis of acroporid coral larvae. The bacterial metabolite tetrabromopyrrole (TBP), isolated from an extract of Pseudoalteromonas sp. associated with the crustose coralline alga (CCA) Neogoniolithon fosliei, induced coral larval metamorphosis (100%) with little or no attachment (0-2%). To better understand the molecular events and mechan...

OBJECTIVES To investigate the antihypertensive activity of aqueous extracts obtained from Malaysian coastal seaweeds and to determine the pharmacological mechanisms of the extracts on rat aorta in vitro. MATERIALS AND METHODS The antihypertensive activity of 11 species of seaweeds (5 brown, 1 red and 5 green algae) were tested by cumulative addition of the extracts to phenylephrine (PE)-preco...

Very few studies have analysed the niches of pelagic protist in details. This is because for most protists, both an accurate species definition and methods for routine detection and quantification of cells are lacking. The morphospecies Micromonas pusilla, a marine unicellular green alga, is the most ubiquitous and cosmopolitan picoeukaryote described to date. This species comprises several ind...

The application of molecular systematics to the parasitic Platyhelminthes (Cestoda, Digenea and Monogenea) over the last decade has advanced our understanding of their interrelationships and evolution substantially. Here we review the current state of play and the early works that led to the molecular-based hypotheses that now predominate in the field; advances in their systematics, taxonomy, c...

The high incidence of vulvo-vaginal candidiasis, combined with the growing problems about azole resistance and toxicity of antifungal drugs, highlights the need for the development of new effective strategies for the treatment of this condition. In this context, natural compounds represent promising alternatives. The cyanobacterium Spirulina platensis, a blue-green alga, exhibits antimicrobial ...

The prevalence of larval stages of Dicrocoeliidae in the land snail, Chondrus tournefortianus (Férussac, 1821), found in Kastamonu, Turkey, was investigated and some of its morphological and histological features were determined. The snail samples were collected in spring and autumn. C. tournefortianus has been reported for the first time as being an intermediate host in the life cycle of Dicro...
