Bacillus subtilis Mobilizes Phosphorus by Reshaping P Pools, Sorption, and Enzyme Activities

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Low phosphorus (P) availability constrains crop production in saline‐alkaline soils of Xinjiang, China. We tested whether Bacillus subtilis (B. subtilis) mobilizes soil P by altering P fractions, sorption–desorption, and P‐cycling enzymes in a saline‐alkaline cotton soil. Under conventional fertilization, B. subtilis was applied at 0 (B0), 15 (

Information disclosure and questionnaires in public tenders

open access: yesThe Scandinavian Journal of Economics, EarlyView.
Abstract Public tenders typically involve uncertainty and unforeseen costs, which might not be fully known to the bidders themselves. This uncertainty may also concern adaptation costs to the procurer after the delivery, and information about such adaptation costs may influence the bidding strategies, even though the cost is paid by the procurer ...

Compartment‐Specific Functional and Taxonomic Responses of Plant Growth‐Promoting Microbiomes Following Oxytetracycline Trunk Injection in Citrus

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 3, September 2026.
ABSTRACT Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus, is the most destructive disease affecting citrus production worldwide. Trunk injection of oxytetracycline (OTC) is increasingly used to suppress the pathogen and improve tree performance, yet its ecological consequences for plant‐associated microbiomes remain poorly understood ...

Effects of pyrroloquinoline quinone and imidazole pyrroloquinoline on biological activities and neural functions

open access: yesHeliyon, 2020
Pyrroloquinoline quinone (PQQ) is contained in fruits and vegetables and in human breast milk. It has been reported that PQQ has high reactivity and changes to an imidazole structure (imidazole pyrroloquinoline) by a reaction with an amino acid at a high

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 24: Suitability of taxonomic units notified to EFSA until March 2026

open access: yesEFSA Journal, Volume 24, Issue 7, July 2026.
Abstract The Qualified Presumption of Safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of knowledge and safety of microorganisms intentionally added to the food and feed chain.

Nacre-inspired magnetically oriented micro-cellulose fibres/nano-hydroxyapatite/chitosan layered scaffold enhances pro-osteogenesis and angiogenesis

open access: yesMaterials Today Bio, 2022
In situ regeneration of large-segment bone defects is a difficult clinical problem. Here, we innovatively developed magnetically oriented micro-cellulose fibres using nano-hydroxyapatite/chitosan (CEF/Fe3O4/HA/CS) and loaded an NFκB pathway inhibitor on ...

Substrate‐Affinitive P‐Type Azapolycyclic Photosensitizer for Chemoselective Nitrilization Under Mild Conditions

open access: yesAdvanced Science, Volume 13, Issue 36, 29 June 2026.
We developed a series of quinoxalinoquinoxaline (QQ) photosensitizers featuring high and tunable excited‐state reduction potentials (E(PC•+/PC*) = –1.76 to –2.05 V vs. SCE). Their hydrogen‐bonding interaction with carbonyl substrates enables selective single‐electron transfer events for selective nitrilization of 1° amides, offering a tunable ...

Red blood cell membrane proteome as a reporter of disease severity, transfusion impact and genetic background in transfusion‐dependent β‐thalassaemia

open access: yesBritish Journal of Haematology, Volume 208, Issue 6, Page 1980-1992, June 2026.
Summary Omics technologies have transformed research in haemoglobinopathies, yet the proteome of RBCs remains largely unexplored in transfusion‐dependent thalassaemia (TDT). In this proteomic analysis, Red blood cell (RBC) membranes from 48 adults with TDT were compared with healthy controls.
