In closed aquatic environments like ponds or lakes, water bloom caused by eutrophication has severely damaged aquatic ecosystems. Some previous studies suggested that submerged macrophytes contribute to the development of aquatic ecosystems and water purification. Although water purification and lake ecosystem restoration using submerged macrophytes have been greatly studied, their specific mec...

Y75N mutant Mucor pusillus pepsin has been overexpressed in yeast, purified and cocrystallized with the iodine-containing human renin inhibitor CP-113972 [(2R,3S]-isopropyl 3-[(L-prolyl-p-iodo-L-phenylalanyl-S-methyl-cysteinyl)amino-4]-cyclohexyl-2-hydroxybutanoate] for X-ray crystallography. Tetragonal complex crystals with space group P4(3)2(1)2 were produced by the hanging-drop vapour-diffus...

We describe an unusual presentation of fatal infection due to Rhizomucor pusillus bloodstream infection in a 12-year old pediatric patient recently diagnosed with hemophagocytic lymphohistiocytosis. R. pusillus was isolated from one blood culture drawn on Day 11 of hospitalization.

were typical of lymphangitis-associated rickettsiosis, and most cases of rickettsioses in southern France in the spring are caused by R. sibirica mongolitimonae. Clustered cases of SFG rickettsiae infection have been reported in Europe, including southern France (3,6). In 2007, R. conorii and R. massiliae infections in humans were reported (3). In 2010, cases for which we were unable to discrim...

Ten species of fungi were obtained from poultry droppings in Nigeria. Six of these are true thermophiles while the other four are thermotolerant. Aspergillus fumigatus Fresenius, Mucor pusillus Lindt and Thermoascus aurantiacus Stolk are known human pathogens. Except for M. pusillus, all the thermotolerant species had a higher occurrence at 45 degrees C while the thermophilic varieties were rea...

Potamogeton is one of the most difficult groups to clarify in aquatic plants, which has an extensive range of interspecific morphological and ecological diversity. Internal transcribed spacer (ITS) is prevalent for phylogenetic analysis in plants. However, most researches demonstrate that ITS has a high percentage of homoplasy in phylogenetic datasets. In this study, eighteen materials were col...

Differences in relative strengths and weaknesses between predators and prey under tactical contexts result in complex and dynamic contests between them. These contests are often brief and difficult to observe in marine systems. Here, we employ basic principles of underwater optics and physics to provide a conceptual understanding of mechanisms underlying predator prey interactions between white...

SummaryThe Near Eastern species of Leptodirini (from Armenia, Georgia, Iran, Israel, Lebanon, Southwestern Russia, Syria and Turkey) are reviewed. The new monospecific genus Mixanigia n. gen. is described for faillei sp. Huetheriella pinargozu described. Catopsinus (Motschulsky, 1868) resurrected four previously placed in Bathysciola Jeannel, 1910: cavazzutii (Giachino, 1996) comb., C. lindberg...
