Conservation of the nucleotide excision repair pathway: characterization of hydra Xeroderma Pigmentosum group F homolog. [PDF]

open access: yesPLoS ONE, 2013
Hydra, one of the earliest metazoans with tissue grade organization and nervous system, is an animal with a remarkable regeneration capacity and shows no signs of organismal aging.

Evolution of hydra, a recently evolved testis-expressed gene with nine alternative first exons in Drosophila melanogaster. [PDF]

open access: yesPLoS Genetics, 2007
We describe here the Drosophila gene hydra that appears to have originated de novo in the melanogaster subgroup and subsequently evolved in both structure and expression level in Drosophila melanogaster and its sibling species. D.

Identification of Components of the Hippo Pathway in Hydra and Potential Role of YAP in Cell Division and Differentiation

open access: yesFrontiers in Genetics, 2021
The Hippo signaling pathway has been shown to be involved in regulating cellular identity, cell/tissue size maintenance and mechanotransduction. The Hippo pathway consists of a kinase cascade which determines the nucleo-cytoplasmic localization of YAP in

Exploring the HYDRAtion method for loading siRNA on liposomes : the interplay between stability and biological activity in human undiluted ascites fluid [PDF]

open access: yes, 2016
Delivery of small interfering RNA (siRNA) is recently gaining tremendous attention for the treatment of ovarian cancer. The present study investigated the potential of different liposomal formulations composed of (2,3-dioleoyloxy-propyl)trimethylammonium

Spectroscopic Confirmation of the Dwarf Galaxies Hydra II and Pisces II and the Globular Cluster Laevens 1 [PDF]

open access: yes, 2015
We present Keck/DEIMOS spectroscopy of stars in the recently discovered Milky Way satellites Hydra II, Pisces II, and Laevens 1. We measured a velocity dispersion of 5.4 (+3.6 -2.4) km/s for Pisces II, but we did not resolve the velocity dispersions of ...

Laboratory test methods to determine the degradation of plastics in marine environmental conditions

open access: yesFrontiers in Microbiology, 2012
In this technology report, three test methods were developed to characterize the degradation of plastic in marine environment. The aim was to outline a test methodology to measure the physical and biological degradation in different habitats where ...

Nerve cell differentiation in hydra requires two signals [PDF]

open access: yes, 1986
Endogenous signals controlling nerve cell commitment in hydra were investigated using an assay for committed nerve precursors. Extracts of hydra tissue were prepared and tested for their ability to induce nerve cell commitment.

The Involvement of Cell-Type-Specific Glycans in Hydra Temporary Adhesion Revealed by a Lectin Screen

open access: yesBiomimetics, 2022
Hydra is a freshwater solitary polyp, capable of temporary adhesion to underwater surfaces. The reversible attachment is based on an adhesive material that is secreted from its basal disc cells and left behind on the substrate as a footprint.
