Background: The separation of runoff components within a model simulation is of great importance for a successful implementation of management measures. Diatoms could be a promising indicator for tile drainage flow due to their diverse preferences to different aquatic habitats. In this study, we collected diatom samples of 9 sites (4 tile drainage, TD, and 5 river sites, Ri) in a German lowland catchment at a weekly or biweekly time step from March to July 2013 with the aim of testing the suitability of diatoms for tile drainage flow, which is typical for lowland catchment...

The development of the mouth in animals has fascinated researchers for decades, and a recent study proposed the modern view of recurrent evolution of protostomy and deuterostomy. Here we expanded our knowledge about conserved traits of mouth formation in chordates, testing the hypothesis that nitric oxide (NO) is a potential regulator of this process. In the present work we show for the first time that NO is an essential cell signaling molecule for cephalochordate mouth formation, as previously shown for vertebrates, indicating its conserved ancestral role in chordates...

Hepatoprotective and reno-potective effect of Sargassum species was investigated in rats against carbon tetrachloride (CCl4) and acetaminophen (AAP) intoxication. The rats were given ethanol extracts of Sargassum ilicifolium, S. lanceolatum and S.swartzii orally at dose of 200mg/kg b.w. (body weight) daily for 14 days. These seaweed treated rats were then intoxicated with single intra-peritoneal dose of CCl4 or AAP on14th day. The administration of CCl4 and AAP caused significant (p<0.05) elevation in liver enzymes; alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH) and other biochemical parameters, bilirubin, glucose, triglyceride and kidney function markers: urea and creatinine...

In 2016, Kaji et al. concluded that the amphioxus mouth has the quality of a coelomoduct and is, therefore, not homologous to the oral opening of any other animal. They studied a Japanese population of Branchiostoma japonicum and based their conclusion, in part, on the larval expression of BMP2/4 in cells that reportedly joined the rim of the forming mouth. They did not detect transcription of that gene in any other tissues in the anterior region of the larva. Their results were almost the inverse of findings for B...

Biological communities in aquatic environments most commonly face multiple stress, where natural and anthropogenic stressors often act jointly. Their interactions are most easily assessed using short cycle organisms such as periphytic diatoms. In this experiment, we analyzed the combined effects of copper exposure and warming on diatom successions over 6 weeks. Natural biofilm collected in winter was left to grow in mesocosms exposed or unexposed to realistic Cu concentrations at four different temperatures...

BACKGROUND: During embryogenesis, tight regulation of retinoic acid (RA) availability is fundamental for normal development. In parallel to RA synthesis, a negative feedback loop controlled by RA catabolizing enzymes of the cytochrome P450 subfamily 26 (CYP26) is crucial. In vertebrates, the functions of the three CYP26 enzymes (CYP26A1, CYP26B1, and CYP26C1) have been well characterized. By contrast, outside vertebrates, little is known about CYP26 complements and their biological roles...

Essential oils (EOs) from plants may be alternative sources of molecules toxic against mosquito vectors of public health relevance. Most of researches in this field focused on EOs as larvicides or ovicides, while limited efforts focused on the exploitation of EOs as oviposition deterrents. In the present study, the larvicidal and oviposition deterrent activity of Syzygium lanceolatum leaf EO was evaluated against six mosquito species, Anopheles stephensi, An. subpictus, Aedes aegypti, Ae. albopictus, Culex quinquefasciatus, and Cx...

Until recently, genes coding for homologues of the autofluorescent protein GFP had only been identified in marine organisms from the phyla Cnidaria and Arthropoda. New fluorescent-protein genes have now been found in the phylum Chordata, coding for particularly bright oligomeric fluorescent proteins such as the tetrameric yellow fluorescent protein lanYFP from Branchiostoma lanceolatum. A successful monomerization attempt led to the development of the bright yellow-green fluorescent protein mNeonGreen. The structures of lanYFP and mNeonGreen have been determined and compared in order to rationalize the directed evolution process leading from a bright, tetrameric to a still bright, monomeric fluorescent protein...

The genus Enghoffosoma is recorded from Vietnam for the first time, altogether with six species involved. Two species, E. lanceolatum Likhitrakarn et al., 2014 and E. anchoriforme Likhitrakarn et al., 2014, were previously known only from the western part of Laos, thus being new to the fauna of Vietnam. One more species, Sundanina fedorenkoi Golovatch, 2016, very recently described from Dak Lak Province, southern Vietnam, is formally transferred to Enghoffosoma, comb. nov., based both on a strict topotype and a sample from Lam Dong Province, southern Vietnam...

The developmental time and survival to eclosion of Anopheles hermsi Barr & Guptavanij fed monotypic and mixed diets of ten food types were examined in laboratory studies. Larvae fed monotypic diets containing animal detritus (freeze-dried rotifers, freeze-dried Daphnia pulicaria, and TetraMin® fish food flakes) and the mixotrophic protistan Cryptomonas ovata developed faster and survived better than larvae that were fed other monotypic diets. Survival to adulthood of larvae fed several concentrations of the diatom Planothidium (=Achnanthes) lanceolatum was poor (<13%) and larval development time was approximately twice that of larvae fed TetraMin® fish food flakes, the standard laboratory diet...

Recent field inventories and taxonomic research in Central Africa have resulted in the discovery of many new orchid species. Five specimens of an apparently new Angraecum species were collected in Gabon and Cameroon. They stand out for their hanging habit and short zig-zag stem. Morphology of leaves and habit is somewhat comparable to Angraecum cultriforme and Angraecum stolzii, two species from East Africa. Flowers of the novelty share the general morphology of Angraecum pyriforme from which the new species is distinguished by being smaller and with a different lip-spur ratio...

BACKGROUND AND AIMS: The genus Limonium (Plumbaginaceae) has long been recognized to have sexual and apomictic (asexual seed formation) modes of reproduction. This study aimed to elucidate phylogeographical patterns and modes of reproduction in diploid and tetraploid Limonium species, namely three putative sexual diploid species with morphological affinities (L. nydeggeri, L. ovalifolium, L. lanceolatum) and three related, probably apomict tetraploid species (L. binervosum, L. dodartii, L...

Cephalochordates, commonly known as amphioxus or lancelets, are the most basal subphylum of chordates. Cephalochordates are thus key to understanding the origin of vertebrates and molecular mechanisms underlying vertebrate evolution. The evolution of developmental control mechanisms during invertebrate-to-vertebrate transition involved not only gene duplication events, but also specific changes in spatial and temporal expression of many genes. To get insight into the spatiotemporal regulation of gene expression during invertebrate-to-vertebrate transition, functional studies of amphioxus gene regulatory elements are highly warranted...

The methanol extract of the leaves of Illicium lanceolatum, indigenous to Fujian Province, People's Republic of China, was found to exhibit antimicrobial activity against the periodontal pathogen Porphyromonas gingivalis, and a bioassay-guided fractionation led to the isolation of two new compounds, 1 and 2, along with two known santalane-type sesquiterpenoids, 3 and 4. The structures of lanceolactone A (1) and lanceolactone B (2) were elucidated by analyzing their 2D NMR spectroscopic data. Compounds 1 and 2 were assigned as new tetranorsesquiterpenoids with a spiroacetal ring and tricyclic structure, respectively...
