Precision Psychobiotics for Gut-Brain Axis Health: Advancing the Discovery Pipelines to Deliver Mechanistic Pathways and Proven Health Efficacy.

Advancing microbiome-gut-brain axis science requires systematic, rational and translational approaches to bridge the critical knowledge gaps currently preventing full exploitation of the gut microbiome as a tractable therapeutic target for gastrointestinal, mental and brain health. Current research is still marked by many open questions that undermine widespread application to humans. For example, the lack of mechanistic understanding of probiotic effects means it remains unclear why even apparently closely related strains exhibit different effects in vivo.

IL-33-activated ILC2s induce tertiary lymphoid structures in pancreatic cancer.

Tertiary lymphoid structures (TLSs) are de novo ectopic lymphoid aggregates that regulate immunity in chronically inflamed tissues, including tumours. Although TLSs form due to inflammation-triggered activation of the lymphotoxin (LT)-LTβ receptor (LTβR) pathway, the inflammatory signals and cells that induce TLSs remain incompletely identified. Here we show that interleukin-33 (IL-33), the alarmin released by inflamed tissues, induces TLSs.

Inheritance and Resistance Mechanisms of Field-Evolved Resistance to Pyrethroids in a Fall Armyworm ( J.E. Smith) (Lepidoptera: Noctuidae) Strain from Puerto Rico.

This study examines resistance inheritance to the pyrethroid insecticides esfenvalerate and deltamethrin in a Puerto Rican strain of fall armyworm (FAW), , a major global pest of corn. The resistant strain (PPR) showed significantly higher resistance compared to a susceptible strain (SUS), with a 62-fold X-linked and 15-fold autosomal-linked resistance ratio (RR) for esfenvalerate and deltamethrin, respectively. Resistance was incompletely dominant for both insecticides.

Vessel strike encounter risk model informs mortality risk for endangered North Atlantic right whales along the United States east coast.

Vessel strikes are a critical threat to endangered North Atlantic right whales (Eubalaena glacialis), significantly contributing to their elevated mortality. Accurate estimates of these mortality rates are essential for developing effective management strategies to aid in the species' recovery. This study enhances existing vessel strike models by incorporating detailed regional data on vessel traffic characteristics as well as whale distribution and behavior.

Dietary sources of free, added, and total sugars in Swedish adolescents.

Purpose: Swedish adolescents' free and added sugars intake exceeds recommended levels. This poses potential health problems; however, little is known about dietary sources within the Swedish population. This study investigated dietary sources of sugars among Swedish adolescents, as well as timing and location of free sugars intake.
