FLZ attenuates Parkinson's disease pathological damage by increasing glycoursodeoxycholic acid production via down-regulating Clostridium innocuum

open access: yesActa Pharmaceutica Sinica B
Increasing evidence shows that the early lesions of Parkinson's disease (PD) originate from gut, and correction of microbiota dysbiosis is a promising therapy for PD.

Effects of Repeated Sand Replenishment Projects on Runs of a Beach-Spawning Fish, the California Grunion

open access: yesJournal of Marine Science and Engineering, 2020
Beach habitats are diminishing globally, particularly in urban areas, as sea-level rise, erosion, and shoreline hardening, along with reduced sediment inputs, combine to squeeze the coast. In California, USA an endemic marine fish, the California grunion,

Substrate-Assisted Catalysis in Sialic Acid Aldolase [PDF]

open access: yes, 2016
Sialic acid aldolase catalyses the reversible aldol condensation of pyruvate and N-acetylmannosamine with an apparent lack of stereospecificity. Consistent with this, modeling of Schiff base and enamine intermediates in the active site of this enzyme ...

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Millimeter Wave Substrate Integrated Waveguide Antennas: Design and Fabrication Analysis [PDF]

open access: yes, 2009
The paper presents a new concept in antenna design, whereby a photo-imageable thick-film process is used to integrate a waveguide antenna within a multilayer structure. This has yielded a very compact, high performance antenna working at high millimeter-

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Numerical study of substrate assimilation by a microorganism exposed to fluctuating concentration [PDF]

open access: yes, 2012
In most modelling works on bioreactors, the substrate assimilation is computed from the volume average concentration. The possible occurrence of a competition between the transport of substrate towards the cell and the assimilation at the cell level is ...
