Natural Products Exhibit Therapeutic Potential in Treating Rheumatoid Arthritis by Targeting the PI3K/Akt Signaling Pathway

Phytotherapy Research, EarlyView.
This review summarizes how natural products, mainly including flavonoids, terpenoids, alkaloids, and polyphenols alleviate RA via PI3K/Akt pathway, regulating inflammation, proliferation, apoptosis, angiogenesis, and osteoclast differentiation. The figure was created by Figdraw (https://www.figdraw.com/#/).

Deep learning‐based super‐resolution reconstruction and improved YOLOv9 for efficient benthos detection: a case study at Lake Hamana, Japan

Remote Sensing in Ecology and Conservation, EarlyView.
This study presents a UAV‐based framework that integrates deep learning‐based super‐resolution reconstruction and an enhanced YOLO detector to improve centimetre‐scale benthic organism monitoring. Using hermit crabs in Lake Hamana, a coastal lagoon in Japan, as a case study, the method substantially enhanced small‐object detection performance ...

Molecular tuning of sea anemone stinging

eLife, 2023
Abstract Jellyfish and sea anemones fire single-use, venom-covered barbs to immobilize prey or predators. We previously showed that the anemone Nematostella vectensis uses a specialized voltage-gated calcium (Ca V ) channel to trigger stinging in ...

Rapid loss, and slow recovery, of coral reef structural complexity resulting from a prolonged marine heatwave

Journal of Animal Ecology, EarlyView.
Using Structure‐from‐Motion photogrammetry in a longitudinal study, we show that although coral reef habitat complexity had declined significantly by the end of the most prolonged tropical marine heatwave on record, no further losses were detected and 3 years later the reef had begun to recover this critical ecosystem function.

Reproductive biology of the sea anemone shrimp Periclimenes rathbunae (Caridea, Palaemonidae, Pontoniinae), from the Caribbean coast of Costa Rica

ZooKeys, 2014
Caridean shrimps are a highly diverse group and many species form symbiotic relationships with different marine invertebrates. Periclimenes rathbunae is a brightly colored shrimp that lives predominantly in association with sea anemones.

Additions to the South African sea anemone (Cnidaria, Actiniaria) fauna, with expanded distributional ranges for known species [PDF]

African Invertebrates, 2016
The last monograph on South African sea anemones was published by Carlgren more than 75 years ago. Since that time, very little taxonomic research has been undertaken on this group and only seven additional species have been added to the regional fauna ...

Direct, but not indirect, predation‐risk cues deter larval settlement in a scyphozoan jellyfish

Journal of Animal Ecology, EarlyView.
Predators can shape population dynamics before consumption occurs, with prey using chemical information to guide larval settlement. We show that jellyfish larvae (Aurelia coerulea) respond selectively to predation‐risk cues, reducing settlement in response to predator presence and active predation cues, but not to residual cues from previously preyed ...

Isolation and cDNA cloning of four peptide toxins from the sea anemone Heteractis aurora [PDF]

Journal of Venomous Animals and Toxins including Tropical Diseases
Background: Sea anemones are well known to contain multiple peptide toxins. However, of more than 1100 species of sea anemones distributed worldwide, only a little over 50 have been studied for peptide toxins.
