Gender-specific function of melatonin receptor (MTRI) in gonads of red swamp crayfish, Procambarus clarkii

Scientific Reports
Melatonin receptor (MTR) plays a crucial role in mediating melatonin signaling. Therefore, it is necessary to study functions and characteristics of MTR. In this study, full length cDNA of MTRI in Procambarus clarkii was cloned.

Therapeutic Effects of Psoralea corylifolia and Morus alba Aqueous Extracts on Tetrahymena pyriformis-Infected Guppies (Poecilia reticulata) and Underlying Transcriptomic Mechanisms: Implications for Ciliate Parasite Control

Animals
Tetrahymena pyriformis is biologically similar to Ichthyophthirius multifiliis, the parasite that causes “white spot disease” in fish. Because it has immune evasion genes and grows quickly, T. pyriformis serves as an ideal model for developing treatments

High Center‐of‐Mass, Multi‐Legged Soft Robots Powered by Geometrically Encoded Liquid Crystal Elastomer Arc Appendages

Advanced Materials, EarlyView.
Inspired by the octopus and the golden wheel spider, soft robots with liquid crystal elastomer arc fibers as appendages are fabricated to transcend surface constraints through an elevated center of mass and minimal contact footprints. By leveraging curvature‐encoded deformation‐recovery cycles, these robots exhibit contractile, torsional, and flexural ...

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

Advanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Body size and dispersal mode as key traits determining metacommunity structure of aquatic organisms

, 2012
Relationships between traits of organisms and the structure of their metacommunities have so far mainly been explored with meta-analyses. We compared metacommunities of a wide variety of aquatic organism groups (12 groups, ranging from bacteria to fish ...
