Abstract

The renowned French composer and musician, Maurice Ravel (1875-1937) exhibited a perplexing case of progressive degenerative neurological symptoms, namely amnesia, aphasia, apraxia, amusia, and alexia. The symptoms started when Ravel was only fairly young, at 57, five years prior to his death in 1937. He was surgically intervened in what was known then as an exploratory craniotomy and passed away. There are a number of publications in which his life and known medical history were dissected and analyzed in an attempt to diagnose the ailment that Ravel suffered. Many diagnoses have been considered, among them Alzheimer’s disease, Pick Disease, primary progressive aphasia, corticobasal degeneration, and complications of head injury following a car crash in 1932. Since an autopsy was not performed, an exact diagnosis is rather unlikely, and no one has been able to confirm or deny any of the aforementioned hypotheses. The authors conducted an extensive revision of existent literature and propose some original ideas regarding Ravel’s neurological condition, mainly the psychological impact of Ravel’s life and experiences and the way they may have influenced his musical genius.

Abstract

Background: The number of children experiencing postnatal situations of neurological risk (such as psycho-motor developmental disorders and delays) after birth has increased in recent years. These infants often require multiple pediatric interventions to address functional problems that might generate stress, anxiety, and discomfort. The aim of the present study is to determine whether the level of salivary cortisol, as a stress marker, increases after hydrotherapy and land-based therapy in children at risk of or currently presenting delayed psycho-motor development. Methods: Saliva samples were collected from 25 children (aged 3–36 months) between June 2022 and January 2023 at the Rehabilitation and Physical Medicine Clinical Management Unit of the Virgen de las Nieves University Hospital, Granada, Spain. Three samples were collected from each child, representing baseline, post-hydrotherapy and post-land-based therapy. Result: All salivary cortisol levels were within the normal range. Resting values were the highest, and both modes of therapy decreased salivary cortisol levels. There were no statistically significant differences between the two therapies. Conclusions: Both therapies appear to be useful for treating children with psychomotor developmental disorders without increasing stress during physiotherapy sessions. Although cortisol levels were slightly higher with hydrotherapy than with land-based therapy, this may be due to the small sample size. [ABSTRACT FROM AUTHOR]

29. Valorization of Saithe (Pollachius virens) Residuals into Protein Hydrolysates—Silaging as Preservation Technology.

Abstract

Silaging can be used as preservation technology to valorize currently discarded raw material into protein hydrolysate on board deep-sea vessels. The aim of this study was to investigate the effect of sorting and raw material freshness on the quality and yield of protein hydrolysates obtained through silaging of saithe (Pollachius virens) viscera. Additionally, the effect of using acidcontaining antioxidants was tested. Out sorting of the liver prior to silaging resulted in slightly higher hydrolysate yields. The hydrolysates with the highest protein contents were obtained from silages made from fresh raw materials (day 0), and the content decreased significantly after longer storage of the raw material (2–3 days at 4 ◦C). Storage of the raw material for 1 day did not affect the quality. However, a significantly higher degree of hydrolysis (DH), content of free amino acids (FAA), and total volatile basic nitrogen (TVB-N) were obtained when raw materials were stored for 3 days. The FAA composition was influenced by the raw material’s freshness, with increases in free glutamic acid and lysine and a decrease in free glutamine after longer storage. None of the studied parameters were significantly affected by out sorting of liver or the addition of antioxidants. Overall, the results indicate that the whole fraction of the viscera can be utilized without reducing the quality of the hydrolysate and that the raw material should be stored for a maximum of 1 day prior to preservation to optimize the quality.

46. Inflammatory bowel disease induces pathological α‐synuclein aggregation in the human gut and brain.

Abstract

Aims: According to Braak's hypothesis, it is plausible that Parkinson's disease (PD) originates in the enteric nervous system (ENS) and spreads to the brain through the vagus nerve. In this work, we studied whether inflammatory bowel diseases (IBDs) in humans can progress with the emergence of pathogenic α‐synuclein (α‐syn) in the gastrointestinal tract and midbrain dopaminergic neurons. Methods: We have analysed the gut and the ventral midbrain from subjects previously diagnosed with IBD and form a DSS‐based rat model of gut inflammation in terms of α‐syn pathology. Results: Our data support the existence of pathogenic α‐syn in both the gut and the brain, thus reinforcing the potential role of the ENS as a contributing factor in PD aetiology. Additionally, we have analysed the effect of a DSS‐based rat model of gut inflammation to demonstrate (i) the appearance of P‐α‐syn inclusions in both Auerbach's and Meissner's plexuses (gut), (ii) an increase in α‐syn expression in the ventral mesencephalon (brain) and (iii) the degeneration of nigral dopaminergic neurons, which all are considered classical hallmarks in PD. Conclusion: These results strongly support the plausibility of Braak's hypothesis and emphasise the significance of peripheral inflammation and the gut‐brain axis in initiating α‐syn aggregation and transport to the substantia nigra, resulting in neurodegeneration.
