Persistence, Effectiveness, and Safety of Upadacitinib in Crohn's Disease and Ulcerative Colitis in Real Life: Results From a Spanish Nationwide Study (Ureal Study).

Introduction: Real-world data on the effectiveness of upadacitinib for inflammatory bowel disease (IBD) are limited. To assess upadacitinib persistence, effectiveness, and safety in a real-world scenario.

Methods: Retrospective multicenter study of patients with IBD who received upadacitinib before 31st December 2022 and at least 12 weeks before the recruitment date.

Successful treatment with durvalumab: A case report and review.

Stage III non-small-cell lung cancer (NSCLC) represents a heterogeneous group of disease entities with multimodality treatments. For most patients, platinum-based doublet with concurrent chemoradiotherapy (CRT) has become the first-choice treatment over the past decade. Immune checkpoint inhibition has revolutionized the management of metastatic NSCLC; however, no major advances in systemic therapy for Stage III NSCLC have been made.

Can Bacterial Endophytes Be Used as a Promising Bio-Inoculant for the Mitigation of Salinity Stress in Crop Plants?-A Global Meta-Analysis of the Last Decade (2011-2020).

Soil salinity is a major problem affecting crop production worldwide. Lately, there have been great research efforts in increasing the salt tolerance of plants through the inoculation of plant growth-promoting endophytic bacteria. However, their ability to promote plant growth under no-stress and salinity-stress conditions remains largely uncertain.

The Perception of Rhizosphere Bacterial Communication Signals Leads to Transcriptome Reprogramming in AZ78, a Plant Beneficial Bacterium.

The rhizosphere is a dynamic region governed by complex microbial interactions where diffusible communication signals produced by bacteria continuously shape the gene expression patterns of individual species and regulate fundamental traits for adaptation to the rhizosphere environment. spp. are common bacterial inhabitants of the rhizosphere and have been frequently associated with soil disease suppressiveness.

Characterisation of the Antibiotic Profile of AZ78, an Effective Biological Control Agent of Plant Pathogenic Microorganisms.

Determining the mode of action of microbial biocontrol agents plays a key role in their development and registration as commercial biopesticides. The biocontrol rhizobacterium AZ78 (AZ78) is able to inhibit a vast array of plant pathogenic oomycetes and Gram-positive bacteria due to the release of antimicrobial secondary metabolites. A combination of MALDI-qTOF-MSI and UHPLC-HRMS/M was applied to finely dissect the AZ78 metabolome and identify the main secondary metabolites involved in the inhibition of plant pathogenic microorganisms.

Isolation of 2,5-diketopiperazines from AZ78 with activity against .

Inhibitory activity of the biocontrol bacterial strain AZ78 is related to the production of cyclo(l-Pro-l-Tyr), a 2,5-diketopiperazine with and toxic activity against and Further investigation of culture filtrate organic extracts showed its ability to produce other 2,5-diketopiperazines. They were isolated and identified by spectroscopic (H NMR and ESIMS) and physic (specific optical rotation) methods as cyclo(l-Pro-l-Val), cyclo(d-Pro-d-Phe), cyclo(l-Pro-l-Leu), and cyclo(d-Pro-l-Tyr). When tested against the phytopathogenic Gram-positive bacterium LMG 3605, cyclo(l-Pro-l-Val) showed a toxic activity similar to chloramphenicol at a comparable concentration.

Concepts and applications of foliar spray for microbial inoculants.

Damages of the (agro)ecosystem by extensive use of chemical fertilizers and pesticides, the global dying of bee populations possibly linked to pesticide spraying, and stricter regulations for pesticide use together with successful use of microbials in IPM programs are pushing on the development and commercialization of new microbial products and a large and growing biostimulants and biocontrol market. This review focuses on microbial inoculants including bacteria, fungi, and viruses used as biostimulant or biocontrol agent for foliar application and covers all important steps from inoculant development to successful field application. Topics presented comprise typical spraying equipment including the importance of the spraying process and relating effects, furthermore formulation development including classification and adjuvants, and thirdly regulatory aspects as currently applied or under discussion.

Maintenance and assessment of cell viability in formulation of non-sporulating bacterial inoculants.

The application of beneficial, plant-associated microorganisms is a sustainable approach to improving crop performance in agriculture. However, microbial inoculants are often susceptible to prolonged periods of storage and deleterious environmental factors, which negatively impact their viability and ultimately limit efficacy in the field. This particularly concerns non-sporulating bacteria.

Design and development of a workflow for microbial spray formulations including decision criteria.

Herein, we present a workflow for the development of talc-based microbial inoculants for foliar spray consisting of four steps. These include together with decision-making criteria (1) the selection of additives based on their capability to wet juvenile maize leaves, (2) their adhesion on the plant, (3) their interaction with the biological systems, and (4) the choice of thickener for good dispersion stability. In total, 29 additives including polysaccharides and proteins, polyols, glycosides, oils, waxes, and surfactants (e.

Vigna unguiculata is nodulated in Spain by endosymbionts of Genisteae legumes and by a new symbiovar (vignae) of the genus Bradyrhizobium.

Vigna unguiculata was introduced into Europe from its distribution centre in Africa, and it is currently being cultivated in Mediterranean regions with adequate edapho-climatic conditions where the slow growing rhizobia nodulating this legume have not yet been studied. Previous studies based on rrs gene and ITS region analyses have shown that Bradyrhizobium yuanmingense and B. elkanii nodulated V.
