Towards the standardization of Hydra vulgaris bioassay for toxicity assessments of liquid samples
Ecotoxicology and Environmental SafetyThe Hydra vulgaris bioassay is recognized as sensitive invertebrate test species for toxicity assessment of real-life environmental mixtures for enforcement and monitoring investigations. The purpose of this study was to characterize the intra-laboratory

Hydra regeneration and epitheliopeptides [PDF]
Developmental Dynamics, 2003 AbstractHydra has been well known for over 200 years for its remarkable regenerative capacity. In addition to small pieces excised from the body, reaggregates of dissociated single cells can also regenerate. Although the cellular events involved in the regeneration process have been well characterized, the underlying molecular mechanisms are yet to be ...

Development, Growth &Differentiation, Volume 68, Issue 7, September 2026.In the stony coral, Acropora tenuis, embryos and larvae have progenitor/undifferentiated cells. Undifferentiated‐like cells differentiate into the pharyngeal stomodeum at an early larval stage, and nerve progenitors possess the dual potential to differentiate into nerve cells and vacuolated hyaline cells, depending on the oral‐aboral position ...

Linalool acts as a fast and reversible anesthetic in Hydra.
PLoS ONE, 2019 The ability to make transgenic Hydra lines has allowed for quantitative in vivo studies of Hydra regeneration and physiology. These studies commonly include excision, grafting and transplantation experiments along with high-resolution imaging of live ...

Aluminium Deposition in Hydras
Folia Biologica, 2009 The aim of this research was to explore, compare and explain the appearance, purpose and possible distribution of aluminium depositions in symbiotic and aposymbiotic hydra species. Al deposition in treated hydras appeared pink as single and multiple aluminium depositions or as clusters in the shape of globular or spot-like structures inside the ...

A MiSeq-HyDRA platform for enhanced HIV drug resistance genotyping and surveillance
Scientific Reports, 2019 Conventional HIV drug resistance (HIVDR) genotyping utilizes Sanger sequencing (SS) methods, which are limited by low data throughput and the inability of detecting low abundant drug resistant variants (LADRVs).

Cell proliferation and differentiation kinetics during spermatogenesis in Hydra carnea [PDF]
, 1985 Spermatogenesis inHydra carnea was investigated. The cell proliferation and differentiation kinetics of intermediates in the spermatogenesis pathway were determined, using quantitative determinations of cell abundance, pulse and continuous labelling ...
