- - The study aimed to identify ultrasound characteristics that indicate submucosal fat deposition (the fat halo sign, FHS) in the intestinal walls of Crohn's disease patients using CT imaging data from 68 patients over 10 years.
- - Results showed that 31% of patients had FHS on CT, with a significant difference in submucosal thickness between those with (4.19 mm) and without FHS (2.41 mm), establishing a threshold of 3.1 mm for ultrasound detection.
- - The findings suggest that marked thickening of the submucosal layer on ultrasound can indicate FHS in Crohn's patients, emphasizing the need for additional methods, like color Doppler, to assess
Bariatric surgery (BS) has several benefits, including resolution of non-alcoholic fatty liver disease (NAFLD) in many patients. However, a significant percentage of patients do not experience improvement in fatty liver after BS, and more than 10% develop new or worsening NAFLD features. Therefore, a question that remains unanswered is why some patients experience resolved NAFLD after BS and others do not.

We carefully measured the individual sensation threshold of a pure tone and recorded immediately after the brain's frequency-following response (FFR) at this intensity using the same stimulator. In contrast to 87-Hz tones, 8-Hz tones elicit an FFR already at sensation threshold.

- The study analyzed liver, kidney, and adipose tissue samples from Yellow-legged Gulls to investigate the relationships between heavy metals/persistent organic pollutants and oxidative stress biomarkers.
- Statistically significant differences in pollutant levels were primarily observed based on the sampling area rather than age or sex of the gulls.
- Positive correlations were found in some cases between specific heavy metals and oxidative stress indicators, although overall, the low levels of pollutants did not appear to significantly impact oxidative stress.
