Summary: This study found that in CKD patients, those on dialysis had lower CortBMD and cortical mineral content Z-scores, and DXA measurements were not predictive of bone density. Biomarkers PTH, ALP, and Ca were moderate predictors of CortBMD, with DXA not improving the predictive model.

Summary: Studies in animal science show that DXA measurements may not perfectly match dissections or chemical analyses, requiring calibration equations. Predictions related to body composition and single nutrient content in pigs show promising results, with potential for creating generic regression equations that yield reliable estimates. DXA could be a useful tool for high-throughput phenotyping in genetic studies, efficiently measuring body composition in a wide range of animals.

Summary: The study investigated the feasibility of slot-scan dual-energy bone densitometry on motorized radiographic equipment for fast quantitative measurements of areal bone mineral density. Results showed accurate and reproducible aBMD measurements across different body sizes and positioning with small errors. Empirical evaluations confirmed the reduction in aBMD errors with proposed procedures on robotic x-ray systems.

Summary: This study examines the unique measurement and quality-control strategies in dual-energy X-ray absorptiometry (DXA) and analyzes the dependence of measured entrance-air-kerma (EAK) on dose sensor type and scan length. The feasibility of using EAK to compare scanner output and the congruence between measured and vendor-reported EAK were also established. The results suggest that DXA scanner stability can be quantified using EAK as a quality-control metric with a variety of solid-state and ion chamber (IC) dose sensors. Measured EAK may vary significantly between different scanners, indicating that measured and reported EAK may not always be comparable.

Summary: DXA is the most common modality for quantitative measurements of bone mineral density, but errors related to this exam are still very common and may impact the final diagnosis and therapy. Operator-related errors, such as wrong patient positioning, error in the acquisition process, or in the scan analysis, can occur during each step of DXA. It is important to recognize and avoid such errors to ensure accurate results.

Summary: This study is the first to assess muscle mass in cancer patients using the D3-creatine dilution method. Regardless of the method used for muscle or lean mass assessment, we observed stronger correlations, greater myopenia agreement, and more significant associations with physical function in male colon cancer patients. However, none of the measures of muscle or lean mass were significantly associated with physical function in female colon cancer patients.

Summary: In recent years, there has been an increase in the occurrence of fowl adenovirus 2 (FAdV-2) in China, posing a significant threat to the poultry industry. This study investigated the epidemiology, phylogenetic relationship, genomic characteristics, and pathogenicity of FAdV-2. The results showed that FAdV-2 was the most commonly detected serotype among various FAdV serotypes. Genetic analysis revealed that these FAdV-2 strains formed a distinct branch within the FAdV-D group and had a high nucleotide similarity with reference strains. Recombination analysis identified recombination events between FAdV-2 and FAdV-11 in some strains. Pathogenicity experiments demonstrated that a recombinant FAdV-2 strain caused a high mortality rate and more severe disease in chickens. These findings contribute to our understanding of FAdV-2 and provide a basis for vaccine development.

Summary: The study investigates the effect of Eimeria infection on gastrointestinal physiology, growth performance, and egg production of Hy-Line W-36 laying hens during peak production. Results show that Eimeria infection negatively affects body weight, feed intake, immune response, and nutrient transporter gene expression. Egg production temporarily ceases in hens infected with high and medium-high dosages of Eimeria.

Summary: This study evaluated the effects of CP and ME on the performance and nutritional value of Japanese quail lay chicken. The results showed that protein and energy levels significantly influenced all productive outcomes except feed conversion ratio. The combination of dietary energy and protein levels had a substantial effect on all egg quality trials evaluated. It is recommended to feed layer Japanese quail between the ages of 8 and 20 weeks during the summer with a dietary energy content of 2,900 kcal ME/kg and 20% CP.

Summary: The study investigates the functional variants associated with chicken eggshell color in the SLCO1B3 gene by measuring the eggshell color of Lueyang black-boned chickens and analyzing the genetic data. It identifies 15 variants in SLCO1B3 that are significantly associated with eggshell color. However, the functional analysis shows that one specific variant, 1B3_SNP108, does not have a significant effect on promoter activity. This study highlights the importance of SLCO1B3 and its variants in breeding eggshell color.

Summary: This study investigated the welfare and health of laying hens in a multitier system. The results showed that the spatial distribution of hens changed with increasing age, and lower-ranking hens preferred to stay in lower tiers to avoid competition but still had access to resources. This improved the welfare and health of the hens near the end of the laying cycle.

Summary: This study examined the effect of risk perceptions on preventive behavior among vendors in the live poultry wholesale market and the live poultry retail market in Guangdong Province using the health belief model and structural equation modeling. The results showed that perceived severity and perceived benefits positively influenced vendors' self-efficacy in the wholesale market, while perceived barriers negatively affected self-efficacy in both the wholesale and retail markets. Moreover, cues to action mediated the relationship between perceived severity, perceived benefits, and self-efficacy, and also mediated the effect of perceived susceptibility among wholesale market vendors.

Summary: The study investigates the impact of exposing chick embryos to antigens via in ovo delivery of poultry-specific lactobacilli on the expression of genes associated with early bursal development and maturation. Results indicate that the supplementation of poultry-specific lactobacilli to chick embryos can accelerate the development and immunological maturation of the bursa of Fabricius.
