Relaxin-like Gonad-Stimulating Peptides in Asteroidea

Biomolecules, 2023
Starfish relaxin-like gonad-stimulating peptide (RGP) is the first identified peptide hormone with gonadotropin-like activity in invertebrates. RGP is a heterodimeric peptide, comprising A and B chains with disulfide cross-linkages. Although RGP had been

Crown-of-thorns starfish [PDF]

Current Biology, 2013
Why ‘crown-of-thorns’? The crown-of-thorns starfish is nearly the largest species of starfish (Asteroidea). It may be 50 cm or more in diameter and can have more than 15 arms. Its ‘crown-of-thorns’ are the long sharp spines that cover its upper surface. What is more, the spines are coated with a saponin toxin, which causes irritation to puncture wounds

Smart Bioinks for 4D Bioprinting: Requirements, Design, and Applications

Advanced Science, EarlyView.
Smart bioinks empower 4D‐bioprinted constructs to dynamically adapt and remodel in response to stimuli, effectively biomimicking native tissues. Artificial Intelligence (AI) and Machine Learning (ML) play a guiding role in their rational design by optimizing relevant properties.

Balancing Exploration and Exploitation Through a Sequential Hybrid of Roach Infestation and Mayfly Algorithms for Constrained Engineering Design Optimization

AI &Innovation, EarlyView.
ABSTRACT Maintaining an effective balance between exploration and exploitation is essential during optimization processes, from mathematical functions to more complex problems such as constrained engineering design optimization, particularly when addressing highly nonlinear issues with numerous local optima and strict feasibility requirements.

Laminar Fluid Ejection for Olfactory Drug Delivery: A Proof of Concept Study

IEEE Journal of Translational Engineering in Health and Medicine
Focal intranasal drug delivery to the olfactory cleft is a promising avenue for pharmaceuticals targeting the brain. However, traditional nasal sprays often fail to deliver enough medication to this specific area. We present a laminar fluid ejection (LFE)

Starfish vesicles

, 2002
We report on an experimental and theoretical study of phospholipid vesicles at small reduced volume. In this regime, vesicle shapes are non-axisymmetric and resemble starfish.

The Distribution of Asterosaponins, Polyhydroxysteroids and Related Glycosides in Different Body Components of the Far Eastern Starfish Lethasterias fusca

Marine Drugs, 2019
Glycoconjugated and other polar steroids of starfish have unique chemical structures and show a broad spectrum of biological activities. However, their biological functions remain not well established. Possible biological roles of these metabolites might

From liquid learning to weaving learning: Negotiating meanings of Children's learning in family travel

British Educational Research Journal, EarlyView.
Abstract Children's learning increasingly extends into everyday informal settings, but what counts as learning in these contexts remains insufficiently understood. Focusing on family travel as a mobile and socioculturally situated informal learning context, this study adopts a sociocultural perspective and uses liquid learning as a sensitising concept ...
