The reaction conditions for the synthesis of Cu-BTC (BTC = benzene-1,3,5-tricarboxylic acid) were elucidated using a continuous-flow microreactor-assisted solvothermal system to achieve crystal size and phase control. A high-rate synthesis of Cu-BTC metal-organic frameworks with BET surface area of more than 1600 m²/g (Langmuir surface area of more than 2000...

Four new elaiophylin macrolides (1–4), together with five known elaiophylins (5–9), have been isolated from cultures of the Indonesian soil bacterium Streptomyces sp. ICBB 9297. The new compounds have macrocyclic skeletons distinct from those of the known dimeric elaiophylins in that one or both of the polyketide chains contain(s) an...
A new method was developed for the analysis of natural and synthetic androgenic steroids and their selected metabolites in aquatic environmental matrices using direct large-volume injection (LVI) high performance liquid chromatography (HPLC) tandem mass spectrometry (MS/MS). Method accuracy ranged from 88 to 108% for analytes with well-matched internal standards. Precision,...

Fungal hyphae are among the most highly polarized cells. Hyphal polarized
growth is supported by tip-directed transport of secretory vesicles, which accumulate temporarily
in a stratified manner in an apical vesicle cluster, the Spitzenkörper. The exocyst complex
is required for tethering of secretory vesicles to the apical plasma membrane. We...

Bodies are often made of repeated units, or serial homologs, that develop using the same core gene regulatory network. Local inputs and modifications to this network allow serial homologs to evolve different morphologies, but currently we do not understand which modifications allow these repeated traits to evolve different levels of...
CodY is known to regulate various virulence properties in several Gram-positive bacteria but has not yet been studied
in the important histotoxic and intestinal pathogen Clostridium perfringens. The present study prepared an isogenic codY-null
mutant in C. perfringens type D strain CN3718 by insertional mutagenesis using the Targetron system. Western...
The origin of the late pre-industrial Holocene (LPIH) increase in atmospheric methane concentrations has been much debated. Hypotheses invoking changes in solely anthropogenic sources or solely natural sources have been proposed to explain the increase in concentrations. Here two high-resolution, high-precision ice core methane concentration records from Greenland and Antarctica...
