Quantitative analysis of cell types during growth and morphogenesis in Hydra [PDF]

, 1973
Tissue maceration was used to determine the absolute number and the distribution of cell types in Hydra. It was shown that the total number of cells per animal as well as the distribution of cells vary depending on temperature, feeding conditions, and ...

Evidence of the Possible Interaction between Ultrasound and Thiol Precursors

Foods, 2020
The effect of ultrasound (20 kHz, 153 μm) on the prefermentation extraction mechanisms in Sauvignon Blanc grapes was studied, focusing on 3-mercaptohexan-1-ol (3MH) and 4-mercapto-4-methyl-pentan-2-one (4MMP) precursors linked to glutathione (GSH ...

Distribution of Interstitial Cells and Differentiating Nematocytes in Nests in Hydra attenuata [PDF]

, 1974
We have used tissue maceration to quantitate interstitial cell nests in Hydra attenuata and thiolacetic acid-lead nitrate staining to quantitate differentiating nematocytes. Most I-cell nests have 2, 4, 8, or 16 cells.

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...
