Microbiology and Molecular Biology Reviews, 2005 SUMMARYTo succeed, many cells must alternate between life-styles that permit rapid growth in the presence of abundant nutrients and ones that enhance survival in the absence of those nutrients. One such change in life-style, the “acetate switch,” occurs as cells deplete their environment of acetate-producing carbon sources and begin to rely on their ...

FEBS Open Bio, EarlyView.We report that some menthol‐like cooling compounds, including (R)‐(‐)‐carvone, act as inhibitors of TAS2R31 and TAS2R43, which are taste receptors responsible for the intrinsic bitter aftertastes of saccharin and acesulfame K. However, there was little correlation between the intensity of the cooling sensation and the potency of bitterness inhibition ...

Structural and functional characterization of chitinase from carnivorous plant Drosera adelae
FEBS Open Bio, EarlyView.A class I chitinase from the carnivorous plant Drosera adelae was expressed and purified using a yeast system, revealing high enzymatic activity. Structural analyses of the catalytic and chitin‐binding domains identified key tyrosine residues involved in substrate binding, offering insights into the enzyme's adaptation for insect digestion.

A student-led comparison of techniques for augmenting the field experience [PDF]
, 2009 We report a study in which 30 university geography students compared five techniques to enhance the experience of visiting outdoor locations. The techniques were: a pre-prepared acetate overlay of the visual scene; a custom-designed visitor guide running

NHC in Imidazolium Acetate Ionic Liquids: Actual or Potential Presence? [PDF]
, 2018 Ionic liquids (ILs) are considered in the majority of cases green solvents, due to their virtually null vapor pressure and to the easiness in recycling them.

FEBS Open Bio, EarlyView.Here, we introduced an intermittent electrical stimulation protocol mimicking the episodic nature of real‐life exercise in vitro by alternating low‐ and high‐frequency stimulation. In comparison with widely used continuous stimulation, it enhanced the rate of glucose and fatty acid oxidation, but not the myokine release.

Mode of attack of hydriodic acid on unsaturated glyceryl ethers
Journal of Lipid Research, 1965 The mode of action of hydriodic acid (HI) on a sample rich in selachyl alcohol [1-O-9(cis)-octadecenyl glycerol] has been studied. HI attacked the olefinic bonds as well as the ether bonds, with the formation of at least two diiodides as well as the ...

FEBS Open Bio, EarlyView.Epigallocatechin‐3‐gallate (EGCG) acutely inhibited gluconeogenesis and enhanced glycolysis, glycogenolysis, and fatty acid oxidation in perfused rat livers. Mechanistic assays revealed mitochondrial uncoupling, inhibition of pyruvate carboxylation and glucose‐6‐phosphatase, shift of NADH/NAD+ ratios toward oxidation, and loss of membrane integrity ...

Direct Observation of Early-stage Quantum Dot Growth Mechanisms with High-temperature Ab Initio Molecular Dynamics [PDF]
, 2015 Colloidal quantum dots (QDs) exhibit highly desirable size- and shape-dependent properties for applications from electronic devices to imaging. Indium phosphide QDs have emerged as a primary candidate to replace the more toxic CdSe QDs, but production of
