The tuna keel is a mechanosensory structure.

Tunas are high-performance pelagic fishes of considerable economic importance and have a suite of biological adaptations for high-speed locomotion. In contrast to our understanding of tuna body and muscle function, mechanosensory systems of tuna are poorly understood. Here we present the discovery of a remarkable sensory lateral line canal within the bilateral tuna keels with tubules that extend to the upper and lower keel surfaces.

The fungal microbiota modulate neonatal oxygen-induced lung injury.

Background: The immature lungs of very preterm infants are exposed to supraphysiologic oxygen, contributing to bronchopulmonary dysplasia (BPD), a chronic lung disease that is the most common morbidity of prematurity. While the microbiota significantly influences neonatal health, the relationship between the intestinal microbiome, particularly micro-eukaryotic members such as fungi and yeast, and lung injury severity in newborns remains unknown.

Results: Here, we show that the fungal microbiota modulates hyperoxia-induced lung injury severity in very low birth weight premature infants and preclinical pseudohumanized and altered fungal colonization mouse models.

Functional classification of tauopathy strains reveals the role of protofilament core residues.

Distinct tau amyloid assemblies underlie diverse tauopathies but defy rapid classification. Cell and animal experiments indicate tau functions as a prion, as different strains propagated in cells cause unique, transmissible neuropathology after inoculation. Strain amplification requires compatibility of the monomer and amyloid template.

Exoskeleton Training for Spinal Cord Injury Neuropathic Pain (ExSCIP): Protocol for a Phase 2 Feasibility Randomised Trial.

Background: Following Spinal Cord Injury (SCI), 53% of people develop neuropathic pain (NP). NP can be more debilitating than other consequences of SCI, and a persistent health issue. Pharmacotherapies are commonly recommended for NP management in SCI, although severe pain often remains refractory to these treatments in many sufferers.

A Novel Fibrinolysis Resistance Capacity Assay Can Detect Fibrinolytic Phenotypes in Trauma Patients.

Background:  To evaluate residual fibrinolysis resistance activity (FRA) in plasma, a detergent-modified plasma clot lysis assay time (dPCLT) was established in which α2-antiplasmin (A2AP) and plasminogen activator inhibitor type 1 (PAI-1) are inactivated without impacting protease activity. We applied this novel assay to severely injured trauma patients' plasma.

Material And Methods:  Tissue-type plasminogen activator (tPA)-induced plasma clot lysis assays were conducted after detergents- (dPCLT) or vehicle- (sPCLT) treatment, and time to 50% clot lysis was measured ("transition midpoint", T ).
