Coexistence Patterns Between Ants And Spiders In Grassland Habitats

Sociobiology, 2014
The ecological importance of both ants and spiders is well known, as well as the relationship between certain spiders and ants. The two main strategies ˗ myrmecomorphy (ant-mimicking) and myrmecophagy (ant-eating) ˗ that connect spiders to ants have been

Biologically‐Inspired Melt Electrowriting for the Generation of Highly Biomimetic Functional Myocardium

Advanced Functional Materials, EarlyView.
In this work, melt electrowriting is used to fabricate a 3D printed scaffold design that generates engineered cardiac tissues with in‐plane contraction, mimicking natural myocardium. It is shown that these tissues display advanced maturation and functionality.

Ploidy differences represent an impassable barrier for hybridization. Is there an exception among botiid loaches (Cypriniformes: Botiidae)?

Frontiers in Marine Science, 2015
One of the most efficient mechanisms to keep animal lineages separate is a difference in ploidy level, since hybrid offspring from parents with different ploidy level are generally sterile.

Integration of Perovskite/Low‐Dimensional Material Heterostructures for Optoelectronics and Artificial Visual Systems

Advanced Functional Materials, EarlyView.
Heterojunctions combining halide perovskites with low‐dimensional materials enhance optoelectronic devices by enabling precise charge control and improving efficiency, stability, and speed. These synergies advance flexible electronics, wearable sensors, and neuromorphic computing, mimicking biological vision for real‐time image analysis and intelligent

“Therapies Through Gut:” Targeted Drug Delivery for Non‐Gastrointestinal Diseases by Oral Administration

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the mechanism of targeted delivery of nanoparticles including 1) paracellular, 2) endolysosomal escape, 3) receptor mediated endocytosis, and 4) M cell mediated transport for non‐GI diseases by oral administration such as atherosclerosis, cancer, diabetes, and brain diseases. Abstract Oral drug delivery is a promising approach

Neural networks for action representation underlying automatic mimicry: A functional magnetic-resonance imaging and dynamic causal modeling study

Frontiers in Human Neuroscience, 2012
Automatic mimicry is based on the tight linkage between motor and perception action representations in which internal models play a key role. Based on the anatomical connection, we hypothesized that the direct effective connectivity from the posterior ...

Neural measures of the causal role of observers' facial mimicry on visual working memory for facial expressions [PDF]

arXiv, 2018
Simulation models of facial expressions propose that sensorimotor regions may increase the clarity of facial expressions representations in extrastriate areas. We monitored the event-related potential marker of visual working memory (VWM) representations, namely the sustained posterior contralateral negativity (SPCN), also termed contralateral delay ...

Short‐Chain Fatty Acids Modulate Anti‐ROR1 CAR T‐Cell Function and Exhaustion in an Intestinal Adenocarcinoma‐on‐Chip Model

Advanced Healthcare Materials, EarlyView.
Short‐chain fatty acids modulate anti‐ROR1 chimeric antigen receptor (CAR) T‐cell function in an intestinal adenocarcinoma‐on‐chip model. Butyrate and propionate reduce cytotoxicity, cytokine release, and infiltration by inducing a regulatory T‐cell phenotype and T‐cell exhaustion via histone deacetylase inhibition.

Hybridization constrains the evolution of mimicry complexes in woodpeckers

Journal of Avian Biology
The evolution of interspecific mimicry does not always result in perfect resemblance between mimics and models. Differences between members of a mimicry complex can be explained by genetic or developmental constraints.

Functionalized Cerium Oxide Nanoparticles Enhance Penetration into Melanoma Spheroids In Vivo through Angiogenesis

Advanced Healthcare Materials, EarlyView.
Melanoma cell spheroid engraftment is optimized in the chicken chorioallantoic membrane overcoming the complexity of other in vivo models. Using this model, greater penetration of cerium oxide nanoparticles (nanoceria) functionalized with heparin in spheroids is observed via enhancement of vascularization than nanoceria alone.
