Background: YouTube (YouTube, LLC, San Bruno, CA, USA) is an easily accessible and increasingly popular source of information on health-related issues. This study evaluated the scientific content and quality of English-language echocardiography videos posted to this Internet platform.
Methods: For this study, 583 videos were identified and evaluated following a YouTube search using the keyword 'echocardiography' in July 2020. A total of 92 videos were included in this study following the application of the study exclusion criteria. Both video quality and scientific content were evaluated based on the DISCERN score, global quality score, content score, and total quality score (TQS), which was calculated by adding the scores of the three aforementioned scoring systems.
Results: The median duration of the included videos was 315 seconds (interquartile range: 173-852 seconds). The median number of views was 33046 (interquartile range: 7445-89012). Twenty-four (26.08%), 43 (46.73%) and 25 (27.17%) videos, respectively, were stratified into the following three groups based on TQS values: group 1 (5-7 points), group 2 (8-11 points) and group 3 (12-14 points). The values of views (median: 45072), video duration (median: 474), power index (median: 80250) and popularity (median: 34) were significantly higher in group 3 than in the other groups. The duration that a video was online was statistically significantly higher in group 1.
Conclusions: The results suggest that YouTube is an important tool for easily sharing health-related information and disseminating it to large audiences. It can be concluded from the growing interest in videos with scientific content and the high quality scores recorded that YouTube offers accurate and quality information about echocardiography.

Inhibition of the polyol pathway by extract: plausible implications for diabetic retinopathy treatment.

Introduction: Diabetic retinopathy is a significant microvascular disorder and the leading cause of vision impairment in working-age individuals. Hyperglycemia triggers retinal damage through mechanisms such as the polyol pathway and the accumulation of advanced glycation end products (AGEs). Inhibiting key enzymes in this pathway, aldose reductase (AR) and sorbitol dehydrogenase (SD), alongside preventing AGE formation, may offer therapeutic strategies for diabetic retinopathy and other vascular complications.

Introduction: Rumen-protected fat (RPF) is a vital dietary energy source for dairy cows. However, the influences of RPF on rumen volatile fatty acid (VFA) content and bacterial communities in goats are poorly documented.
Methods: In this study, 12 castrated male goats (body weight [BW]: 13.
Organic trace elements enhance growth performance, antioxidant capacity, and gut microbiota in finishing pigs.

Excessive inorganic trace elements are added to livestock and poultry feed to meet the needs of animals, accompanied by frequent occurrence of excretion and gastrointestinal stress. Replacing inorganic trace elements with organic trace elements provides a promising solution to alleviate these problems. Therefore, this study aimed to assess the impact of replacing all inorganic trace elements (ITMs) in feed on the growth performance, meat quality, serum parameters, trace element metabolism, and gut microbiota of finishing pigs.

Vertical Farming Systems (VFS) emerge as an approach to optimize plant growth in urban and controlled environments, by enabling sustainable and intensive production in reduced spaces. VFS allow for greater control over growing conditions, such as light, temperature and humidity, resulting in higher quality crops and with less use of resources, such as water and fertilizers. This research investigates the effects of different lighting regimes (Constant and Gaussian) and spectral qualities (white, RBW, blue and red) on the growth, photosynthesis, and biomass accumulation of lentil microgreens () in VFS.
