56 cases of primary and post-traumatic Sudeck's disease, treated with Sandoz synthetic salmon calcitonine are reported. The results obtained suggest that this drug should be considered of choice in this type of pathology provided it is administered with the right, highish doses. 2 completely cured cases of stemming of bone cyst using the same product are also reported.

Giant unilamellar vesicles (GUVs) are versatile cell models in biomedical and environmental research. Of the various GUV production methods, hydrogel-assisted GUV production is most easily implemented in a typical biological laboratory. To date, agarose, polyvinyl alcohol, cross-linked dextran-PEG, polyacrylamide, and starch hydrogels have been used to produce GUVs.

In Chile, Atlantic salmon and rainbow trout face significant production challenges due to the presence of Flavobacterium psychrophilum, which generates severe disease issues and economic losses. To address this, the salmon industry relies on vaccines and antibiotics, the latter raising concerns about bacterial resistance. For that reason, our study explores an alternative strategy for controlling F.

We are interested in studying the catalytic activity of the spin crossover (SCO) complex ([Fe(NHtrz)](NO)). In this work, we demonstrate that, by adapting the experimental conditions, we can switch from a quantitative post-synthetic modification (PSM) reaction to the use of this complex as a catalyst for the formation of imine from 4-amino-1,2,4-triazole. During the catalytic reaction, the iron complex undergoes two different PSM reactions: the first is the action of the aldehyde on the NH groups present on the complex, whereas the second PSM reaction occurs between the imine complex and aminotriazole, leading back to the starting complex.

In this paper, we report the synthesis of six novel triazole-based heteroscorpionate ligands based on heterocycle metathesis reactions and their iron(II) complexes. Single crystal structure analyses were performed, the spectroscopic and magnetic properties of the obtained complexes were studied and their spin crossover-structural relationships were compared to those obtained for their pyrazole-based analogues reported in the literature. In particular, the amino derivative complex bis[hydrobis(pyrazol-1-yl)(3-amino-1,2,4-triazol-1-yl)]iron(II) obtained by post-synthetic catalytic nitro-group reduction under pressure of hydrogen in an autoclave presents a scarce gradual spin crossover behavior at room temperature.

The demand for novel tissue grafting and regenerative wound care biomaterials is growing as traditional options often fall short in biocompatibility, functional integration with human tissue, associated cost(s), and sustainability. Salmon aquaculture generates significant volumes of waste, offering a sustainable opportunity for biomaterial production, particularly in osteo-conduction/-induction, and de novo clinical/surgical bone regeneration. Henceforth, this study explores re-purposing salmon waste through a standardized pre-treatment process that minimizes the biological content, followed by a treatment stage to remove proteins, lipids, and other compounds, resulting in a mineral-rich substrate.
