Effect of atmospheric organic complexation on iron-bearing dust solubility [PDF]

open access: yesAtmospheric Chemistry and Physics, 2013
Recent studies reported that the effect of organic complexation may be a potentially important process to be considered by models estimating atmospheric iron flux to the ocean. In this study, we investigated this process effect by a series of dissolution

Exploring the Impact of Polystyrene Microplastic Beads on Male Gonads of the Marine Mussel, Mytilus galloprovincialis

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Plastic, with its remarkable versatility and numerous applications, has greatly benefited humanity. However, its extreme resistance to natural degradation means it persists in the environment for long periods, causing global environmental problems.

Fat synthesis in cell-free preparations of the locust fat-body

open access: yesJournal of Lipid Research, 1961
It was shown that cell-free preparations of the fat-body of the migratory locust, Locusta migratoria, incorporated acetate into fatty acids in the presence of ATP, CoA, glutathione, Mg++, TPN, malonate, α-ketoglutarate, and KHCO3.

Enzymatic synthesis of bioactive quinolones and (thio)coumarins by fungal type III polyketide synthases

open access: yesThe FEBS Journal, EarlyView.
Quinolones are valuable scaffolds for drug discovery but are rare in nature. Here, we show that two fungal enzymes, AthePKS and FerePKS, can generate 2‐quinolones and two additional heteroaromatic scaffolds. Using AthePKS, we designed an artificial enzymatic cascade towards an antimicrobial quinolone from a simple precursor and implemented it in E ...

catena-Poly[[(2,9-dimethyl-1,10-phenanthroline-κ2N,N′)cobalt(II)]-μ-malonato-κ4O1,O1′:O3,O3′]

open access: yesActa Crystallographica Section E, 2010
In the title compound, [Co(C3H2O4)(C14H12N2)]n, the CoII ion is in a distorted octahedral coordination being chelated by a 2,9-dimethyl-1,10-phenanthroline molecule (dmphen) and two carboxylate groups of two malonate ligands The malonate ligand acts in a

Hydrogenative Cyclopropanation and Hydrogenative Metathesis

open access: yes, 2019
The unusual geminal hydrogenation of a propargyl alcohol derivative with [CpXRuCl] as the catalyst entails formation of pianostool ruthenium carbenes in the first place; these reactive intermediates can be intercepted with tethered alkenes to give either

Proteomic analysis of the zone of degeneration at the mitosis–meiosis transition stage in wild‐caught male catshark (Scyliorhinus canicula), correlated with an unusually high‐water temperature in the English Channel

open access: yesJournal of Fish Biology, EarlyView.
Abstract In the context of current global change, variations in water temperature are one of the environmental conditions with serious consequences for marine life, including reproductive processes. In the small spotted catshark Scyliorhinus canicula, spermatogenesis occurs in spermatocysts composed of synchronously developing germ cells associated ...

Multi‐Omics Signatures of Periodontitis and Periodontal Therapy on the Oral and Gut Microbiome

open access: yesJournal of Periodontal Research, EarlyView.
This multi‐omics study integrates shotgun metagenomics and NMR metabolomics to reveal coordinated microbial and metabolic signatures of periodontitis across the oral–gut axis. Non‐surgical periodontal therapy partially restored ecological and functional balance, supporting oral health as a modifiable driver of systemic microbial homeostasis.

Dimethyl 2-(2-quinolylmethyl)malonate

open access: yesActa Crystallographica Section E, 2010
In the title compound, C15H15NO4, the quinoline ring system and one of the malonate side chains are essentially coplanar (r.m.s. deviation = 0.0297 Å).
