AI Article Synopsis
- The study aimed to explore how a specific dietary supplement affects intramuscular fat deposition in heat-stressed beef cattle, using 32 Jinjiang bulls divided into four groups based on supplement dosage.
- Results indicated that the treatment increased crude fat and certain fatty acids, while reducing blood leptin levels, suggesting improved fat deposition.
- High-throughput RNA sequencing revealed significant changes in gene expression related to lipid metabolism, highlighting the supplement's role in enhancing fat deposition under heat stress conditions.
Article Abstract
To investigate the effect of on intramuscular fat deposition in heat-stressed beef cattle and its underlying mechanism. Thirty-two healthy Jinjiang bulls were randomly divided into four groups and dietary with 0 (Control), 200 (Pue200), 400 (Pue400), and 800 (Pue800) mg/kg in the feed concentrate. The results showed that treatment enhanced the concentration of crude fat, fatty acid (C14:1 and C17:1), and the activity of fatty acid synthase in (LT), but decreased the levels of blood leptin ( < 0.05). High-throughput sequencing of mRNA technology (RNA-Seq) was used and the analysis showed that 492 genes were down-regulated and 341 genes were up-regulated in LT, and these genes were significantly enriched to the pathways related to lipid metabolism. These results indicated that dietary supplemental with enhanced intramuscular fat deposition by regulating lipid metabolism of heat-stressed beef cattle.

Central body fat distribution affects kidney function. Abdominal fat measurements using computed tomography (CT) may prove superior in assessing body composition-related kidney risk in living kidney donors. This retrospective cohort study including 550 kidney donors aimed to determine the association between CT-measured abdominal fat areas and kidney function before and after donor nephrectomy.

Background: INTER- and INTRAmuscular fat (IMF) is elevated in high metabolic states and can promote inflammation. While magnetic resonance imaging (MRI) excels in depicting IMF, the lack of reproducible tools prevents the ability to measure change and track intervention success.
Methods: We detail an open-source fully-automated iterative threshold-seeking algorithm (ITSA) for segmenting IMF from T1-weighted MRI of the calf and thigh within three cohorts (CaMos Hamilton (N = 54), AMBERS (N = 280), OAI (N = 105)) selecting adults 45-85 years of age.

This study aimed to evaluate the intake, performance, quality, and fatty acids (FA) composition of the meat of three Nigerian sheep breeds (Balami, Uda, and Yankasa) fed two different hays, Brachiaria decumbens or Digitaria smutsii. A total of sixty sheep, twenty from each breed, Balami, Uda, and Yankasa, were used, with average body weights of 24.7 ± 3.

Article Synopsis
- High-dose testosterone replacement therapy (TRT) combined with finasteride offers benefits such as improved body composition, muscle strength, and bone density in older men, while mitigating the risk of prostate enlargement.
- A pilot study involved 12 men with spinal cord injuries, demonstrating that TRT with finasteride significantly increased lean body mass and muscle size, alongside enhancing bone mineral density compared to a placebo.
- Results suggest TRT + finasteride reduced fat mass and improved muscular strength, with measurable benefits observed as early as 6 months into the treatment, indicating its potential effectiveness for men with low testosterone post-injury.

Previously, animal breeding prioritized enhancing key economic traits to improve production efficiency, leading to a gradual difference in meat quality. However, the genetic factors influencing meat quality remain unclear. To identify key genetic pathways contributing to meat quality, native Chinese yellow-feathered chicken (Qingyuan Partridge Chicken, QPC; female, n=10), and commercial chicken broiler (Cobb broiler, CB; female, n=10) were used for meat quality assessment through metabolomics, proteomics, and phosphoproteomics sequencing.
