HYpofractionated, dose-redistributed RAdiotherapy (HYDRA) versus conventional radiotherapy for head and neck cancer: planned interim analysis and dosimetric comparison from the phase I HYDRA trial [PDF]

open access: yesClinical and Translational Radiation Oncology
Purpose: (Chemo)radiotherapy for squamous cell carcinoma of the oropharynx, hypopharynx, and larynx results in significant treatment burden and may cause radiation-induced lymphopenia (RIL), which is associated with worse survival.

Wnt signaling restores evolutionary loss of robust foot regeneration rates in Hydra [PDF]

open access: yesNature Communications
The regenerative potential of animals varies widely, even among closely related species. In a comparative study of regeneration across the Hydra genus, we found that while most species exhibit robust whole-body regeneration, Hydra oligactis and other ...

Half-Life of Biodegradable Plastics in the Marine Environment Depends on Material, Habitat, and Climate Zone

open access: yesFrontiers in Marine Science, 2021
The performance of the biodegradable plastic materials polyhydroxybutyrate (PHB), polybutylene sebacate (PBSe) and polybutylene sebacate co-terephthalate (PBSeT), and of polyethylene (LDPE) was assessed under marine environmental conditions in a three ...

State of the Art Offshore In Situ Monitoring of Microplastic

open access: yesMicroplastics, 2022
Microplastics make up a significant amount of the overall quantity of plastic debris that is present in seawater. However, their detection and monitoring at sea is cost-inefficient and challenging; typically, it consists of water sampling with special ...

DNA Repair Repertoire of the Enigmatic Hydra

open access: yesFrontiers in Genetics, 2021
Since its discovery by Abraham Trembley in 1744, hydra has been a popular research organism. Features like spectacular regeneration capacity, peculiar tissue dynamics, continuous pattern formation, unique evolutionary position, and an apparent lack of ...

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.
