Photosensitivity of the Central Nervous System of Limulus polyphemus [PDF]

Zoological Science, 2004
The photosensitivity of the central nervous system (CNS) of the horseshoe crab, Limulus polyphemus, was investigated by analyzing changes in motor nerve activity in the segmental nerves of prosomal and opisthosomal ganglia. Spontaneous efferent impulses were recorded in the dark from all the investigated segmental nerves.

Evaluation for endotoxin in intraocular materials used during phacoemulsification surgery using a recombinant factor C assay

Veterinary Ophthalmology, Volume 28, Issue 2, Page 481-485, March 2025.
Abstract Objective Cataract surgery remains the sole method to resolve blindness secondary to cataract formation. One complication includes fibrin web formation post‐operatively. This study aimed to investigate the presence of endotoxin within materials used during cataract surgery as a possible cause of fibrin web phenomenon. Methods Preservative‐free

Atlantic Horseshoe Crabs and Endotoxin Testing: Perspectives on Alternatives, Sustainable Methods, and the 3Rs (Replacement, Reduction, and Refinement)

Frontiers in Marine Science, 2020
Endotoxin testing is a vital part of quality and safety control in pharmaceutical production. The primary method for this testing in North America and Europe is the limulus amebocyte lysate (LAL) test, a critical component of which is the blood of ...

Transition From Land to Sea: Comparative Genomics Illuminates the Adaptive Evolution of the Intertidal Spider

Molecular Ecology Resources, Volume 26, Issue 4, May 2026.
ABSTRACT Spiders are renowned for their ecological versatility and silk‐based innovations in materials science, yet marine environments remain virtually uncolonized by this predominantly terrestrial lineage. A striking exception is the obligate intertidal spider genus Desis, whose members have evolved extraordinary physiological and behavioural ...

Human α2‐Macroglobulin: Architecture, Mechanisms, and Functional Implications

The FASEB Journal, Volume 40, Issue 8, 30 April 2026.
Visual representation of human α2‐macroglobulin in its native and induced conformations. General functions associated with the native form (green), the induced form (white), and both conformations (light red) are indicated. ABSTRACT α2‐Macroglobulin (α2M) is a large glycoprotein and one of the most abundant proteins found in the plasma of vertebrates ...

A UAV‐based deep learning pipeline for intertidal macrobenthos monitoring: Behavioral and age classification in Tachypleus tridentatus

Remote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 242-259, April 2026.
The endangered tri‐spine horseshoe crab (Tachypleus tridentatus), a “living fossil” crucial to coastal ecology and biomedical research, is experiencing severe population declines. Effective conservation requires efficient monitoring, which traditional methods cannot deliver at scale. We develop an integrated UAV deep learning framework tailored to this

A Field‐Friendly, Non‐Toxic Fixative for Integrated Morphological and Molecular Research in Non‐Model Invertebrates

Ecology and Evolution, Volume 16, Issue 2, February 2026.
Formalin, ethanol, and RNAlater are commonly used fixatives for morphological and molecular studies, but each has limitations when specimen availability is low, as is often the case with field‐collected non‐model organisms. Here, we evaluate KINFix, a non‐toxic alcohol‐based fixative, in four invertebrate taxa and show that it effectively preserves ...
