Cis‐unsaturated sphingolipids support growth of sphingoid base‐deficient yeast but impair plasma membrane integrity

open access: yesFEBS Open Bio, EarlyView.
Sphingoid base structures, the sphingolipid backbones, vary among species. We established yeast cells in which the native sphingoid base was replaced with plant‐type bases containing cis or trans double bonds. This is, to our knowledge, the first eukaryotic model mostly composed of sphingolipids containing cis‐unsaturated sphingoid base, providing a ...

Exploring the Use of High-Resolution Satellite Images to Estimate Corn Silage Yield Within Field

open access: yesRemote Sensing
Corn (Zea mays L.) silage yield monitor data offer crucial insights into spatial and temporal yield variability. However, equipment’s sensor malfunctioning can result in data loss, and yield sensor systems are expensive to purchase and maintain.

Urban nutrient balance for Bankok [PDF]

open access: yes, 2001
To enhance agricultural sustainability, former linkages between agriculture and urban waste production should be reintroduced. Therefore, to explore the options for recycling of nutrients from mega-cities, a nutrient balance model was developed.

The effects of arbuscular mycorrhizal fungi (AMF) and Rhizophagus irregularis on soil microorganisms assessed by metatranscriptomics and metaproteomics

open access: yes, 2019
Arbuscular mycorrhizal fungi (AMF) form symbioses with approximately 80% of plant species and potentially benefit their hosts (e.g. nutrient acquisition) and the soil environment (e.g. soil aggregation).

Most autophagic cell death studies lack evidence of causality

open access: yesFEBS Open Bio, EarlyView.
Of 104 studies claiming autophagic cell death (ACD), only 13 demonstrated both causality and exclusion of apoptosis to confirm true ACD. Most studies relied on correlation‐level data or measured autophagy in isolation, revealing pervasive methodological shortcomings.

Microbial profile of the appendix niche in acute appendicitis: a novel sampling approach

open access: yesFEBS Open Bio, EarlyView.
This study utilized a novel sampling method, ERAT (i.e. endoscopic retrograde appendicitis treatment)‐guided lumen aspiration, to obtain samples from the appendix, and shotgun metagenomic sequencing was performed for in situ characterization of the appendix microbiome in patients with acute appendicitis.

A Fungi-Driven Sustainable Circular Model Restores Saline Coastal Soils and Boosts Farm Returns

open access: yesHorticulturae
Agricultural production in the saline–alkaline soils of the Yellow River Delta faces persistent challenges in waste recycling and soil improvement. We developed a three-stage circular agriculture model integrating “crop straw–edible mushrooms–vegetables,”

Transcriptional regulation of neuropeptide receptors underlies context‐dependent adaptation in Drosophila melanogaster

open access: yesFEBS Open Bio, EarlyView.
Under environmental changes, the expression level of neuropeptide (NP) and neuropeptide receptor (NPR) genes changes to confer context‐dependent adaptation to the model organism Drosophila melanogaster. Through finding more regulatory elements in the NPR genes in comparison with their ligands (NPs), we found that NPR‐biased transcriptional regulation ...

Properties of Random Complex Chemical Reaction Networks and Their Relevance to Biological Toy Models

open access: yes, 2013
We investigate the properties of large random conservative chemical reaction networks composed of elementary reactions endowed with either mass-action or saturating kinetics, assigning kinetic parameters in a thermodynamically-consistent manner.

Ion Exchange for Nutrient Recovery Coupled with Biosolids-Derived Biochar Pretreatment to Remove Micropollutants [PDF]

open access: yes, 2018
Wastewater, especially anaerobic treatment effluent, contains high ammonia nitrogen (NH4-N) and inorganic orthophosphate (PO4-P), which necessitate additional treatment to meet stringent discharge regulations.
