Multi‐Targeting Carnosic Acid Kills Drug‐Resistant Helicobacter pylori With Narrow‐Spectrum Activity

Advanced Science, EarlyView.
Carnosic acid selectively eradicates drug‐resistant Helicobacter pylori through a multi‐targeted mechanism involving urease inhibition, membrane disruption, and biofilm eradication. It exhibits no detectable resistance, potent in vivo efficacy, and minimal impact on gut microbiota, positioning it as a promising narrow‐spectrum lead compound against ...

Inside‐Outside ROS Therapeutic Strategy Based on Piezoelectric Nano‐Urchin for Drug‐Resistant Bacteria Biofilm Infections

Advanced Science, EarlyView.
The contribution of this study lies not only in enabling effective treatment of drug‐resistant biofilm infections, but also in establishing a transferable therapeutic paradigm: Ultrasound‐triggered mechanical forces synergistically enhance piezoelectric polarization and nanozyme activity, driving functional ROS generation inside and outside biofilms ...

Biological processing of organics: the fate of leaf litter in the natural environment

, 2003
This paper addresses litter decomposition in the terrestrial catchment of a wetland, and the consequent release of phosphorus (P). Microbial activity and P dynamics were monitored before and after the onset of winter rain along a transect from the bed of

Denitrification and availability of carbon and nitrogen in a well-drained pasture soil amended with particulate organic carbon

, 2011
A well-drained soil in N-fertilized dairy pasture was amended with particulate organic carbon (POC), either sawdust or coarse woody mulch, and sampled every 4 wk for a year to test the hypothesis that the addition of POC would increase denitrification ...

A Single‐Cell Transcriptomic Atlas of the Ovine Rumen Microbiome Characterizes Lineage‐Specific Metabolic Shifts Associated with Host Heat Tolerance

Advanced Science, EarlyView.
An optimized single‐cell transcriptomic framework profiles over 60 000 cells to map the ovine rumen microbiome, partitioning the ecosystem into seven cross‐species functional clusters. In heat‐resistant hosts, a lineage‐specific metabolic shift in Anaerovibrio lipolyticus toward a highly glycolytic phenotype contributes to a “nutritional sparing ...

Simulated litter input drives shifts in carbon allocation strategies within alpine meadows of the three rivers source region

Frontiers in Plant Science
To reveal the transformation in carbon allocation strategies of alpine meadows in the Three Rivers Source Region under litter input.MethodsWe conducted an experimental study on litter input in alpine meadow in Chengduo County, Qinghai Province, with the ...

Differences in soil biological activity by terrain types at the sub-field scale in central Iowa US.

PLoS ONE, 2017
Soil microbial communities are structured by biogeochemical processes that occur at many different spatial scales, which makes soil sampling difficult.

Increased microbial growth, biomass, and turnover drive soil organic carbon accumulation at higher plant diversity

Global Change Biology, 2019
Species‐rich plant communities have been shown to be more productive and to exhibit increased long‐term soil organic carbon (SOC) storage. Soil microorganisms are central to the conversion of plant organic matter into SOC, yet the relationship between ...

Measuring soil microbial biomass using an automated procedure

, 2011
Here we outline the development of the first automated procedure for measuring soil microbial biomass carbon (biomass C) by Fumigation–Extraction (FE) and on which this Citation Classic is based. The method (and its later variations) has been used widely
