Nephrocalcinosis is a widespread challenge in intensive production of salmon smolt. There is however no consensus on its aetiology, which makes it problematic to implement proper measures to limit its development. We performed a survey of nephrocalcinosis prevalence and environmental factors in 11 different hatcheries in Mid-Norway as well as a 6-month monitoring in one of the hatcheries.

- Nephrocalcinosis is a prevalent issue in farmed Atlantic salmon that affects their kidney function, but its effects on overall fish health are not fully understood.
- A transcriptome study showed that salmon with severe nephrocalcinosis exhibited significant changes in gene expression, including reduced metabolism and energy production, along with increased activation of tissue repair and inflammatory responses.
- These gene regulation changes, combined with tissue damage, could severely impact the survival of infected salmon.
Assimilation and turnover rates of lipid compounds in dominant Antarctic copepods fed with C-enriched diatoms.
Philos Trans R Soc Lond B Biol Sci
August 2020
The study revealed species- and stage-specific differences in lipid accumulation of the dominant Antarctic copepods, the primarily herbivorous (copepodite stage V (CV), females) and the more omnivorous (females) storing wax esters and triacylglycerols, respectively, which were collected in summer (end of December). Feeding carbon-labelled diatoms to these copepods, C elucidated assimilation and turnover rates of copepod total lipids as well as specific fatty acids and alcohols. The C incorporation was monitored by compound-specific stable isotope analysis (CSIA).

Methods: In a multicentric regional study (Poitou-Charentes area) during the first trimester 2010, we measured the 25-OH vitamin D serum level in 170 consecutive MS patients, and in 170 controls matched for age (±4 years), sex and date of blood sample analysis. We searched for correlations between 25-OH vitamin D serum levels and the MS form, the disability (EDSS), the relapse rate during the previous year and the presence and number of enhancing lesions on T1-weighted MRI dating less than 12 months in relapsing MS.
