A systems biology approach reveals major metabolic changes in the thermoacidophilic archaeon Sulfolobus solfataricus in response to the carbon source L-fucose versus D-glucose [PDF]

open access: yes, 2016
Archaea are characterised by a complex metabolism with many unique enzymes that differ from their bacterial and eukaryotic counterparts. The thermoacidophilic archaeon Sulfolobus solfataricus is known for its metabolic versatility and is able to utilize ...

Akkermansia muciniphila‐derived hypoacylated rough‐type lipopolysaccharides alleviate diet‐induced obesity via activation of TLR4−IL‐23−IL‐22 immune axis

open access: yesiMeta, EarlyView.
This study demonstrates that hypoacylated, rough‐type lipopolysaccharides (LPS) derived from Akkermansia muciniphila strain HW07 (ALPS) alleviates diet‐induced obesity. ALPS acts as a weak TLR4 agonist and significantly reduces weight gain, improves metabolic parameters, and restores gut barrier integrity in obese mice.

Characterization of a monoclonal antibody that induces the acrosome reaction of sea urchin sperm. [PDF]

open access: yes, 1987
A monoclonal antibody, J18/29, induces the acrosome reaction (AR) in spermatozoa of the sea urchin Strongylocentrotus purpuratus. J18/29 induces increases in both intracellular Ca2+ and intracellular pH similar to those occurring upon induction of the AR

p53 directly regulates the glycosidase FUCA1 to promote chemotherapy-induced cell death [PDF]

open access: yes, 2016
p53 is a central factor in tumor suppression as exemplified by its frequent loss in human cancer. p53 exerts its tumor suppressive effects in multiple ways, but the ability to invoke the eradication of damaged cells by programmed cell death is considered

Characterization of Newly Discovered Polyester Polyurethane‐Degrading Methylobacterium aquaticum Strain A1

open access: yesJournal of Basic Microbiology, EarlyView.
ABSTRACT In this study, we present Methylobacterium aquaticum A1, a novel strain capable of degrading polyester polyurethane (PE‐PUR). The attachment of M. aquaticum A1 to PE‐PUR and its degradation capabilities were verified using Scanning Electron Microscopy (SEM) and Fourier‐Transform Infrared Spectroscopy (FT‐IR).

Novel expression of Haemonchus contortus vaccine candidate aminopeptidase H11 using the free-living nematode Caenorhabditis elegans [PDF]

open access: yes, 2013
With the problem of parasitic nematode drug resistance increasing, vaccine development offers an alternative sustainable control approach. For some parasitic nematodes, native extracts enriched for specific proteins are highly protective.

Production and fate of macroalgal carbon in the ocean: How much do macroalgal organics matter?

open access: yesLimnology and Oceanography Letters, EarlyView.
Abstract Global carbon sequestration by macroalgae is hypothesized to rival rates in other blue carbon ecosystems. However, quantifying macroalgal carbon sequestration is challenging as it is hypothesized to occur outside macroalgal ecosystems, with 73% of sequestration occurring when dissolved organic carbon (DOC) is exported to deep ocean waters.

Protein glycosylation in lung cancer from a mass spectrometry perspective

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Lung cancer is a severe disease for which better diagnostic and therapeutic approaches are urgently needed. Increasing evidence implies that aberrant protein glycosylation plays a crucial role in the pathogenesis and progression of lung cancer.

Characterization of the Lipopolysaccharide from a \u3cem\u3eRhizobium phaseoli\u3c/em\u3e Mutant that is Defective in Infection Thread Development [PDF]

open access: yes, 1987
The lipopolysaccharide (LPS) from a Rhizobium phaseoli mutant, CE109, was isolated and compared with that of its wild-type parent, CE3. A previous report has shown that the mutant is defective in infection thread development, and sodium dodecyl sulfate ...
