Article Synopsis
  • The study aimed to assess how replacing fish meal or chicken meal with yeast culture affects bullfrog growth, serum biochemistry, and intestinal health.
  • The results showed that the FM50 group had poorer growth performance and altered serum biochemistry compared to the control group, while the other experimental groups did not differ significantly from the control.
  • Some groups exhibited enhanced digestive enzyme activities and liver antioxidant capacity, but the FM50 group had reduced intestinal villi height, suggesting that complete replacement of fish or chicken meal might negatively impact some health indicators.

Article Synopsis
  • This study explored the potential link between radiotherapy (RT) given for esophageal cancer (EC) and the risk of developing secondary head and neck cancer (SHNC).
  • Using data from the SEER database, researchers found that EC patients who received RT had a higher incidence of SHNC compared to those who did not receive radiation, with significantly lower overall survival rates for RT patients who developed SHNC.
  • The findings suggest that radiation oncologists should consider strategies to reduce the long-term risk of SHNC in EC patients treated with RT.

Special Chinese propolis sourced from the Changbai Mountains (CBMP) in Northeast China is rich in specific flavonoids and phenolic acids and its bioactivity has not been reported. This study aimed to investigate the antiproliferative effect of CBMP on cancer cells and its molecular mechanisms. Different cancer cell lines were treated with the ethanol extracts of CBMP for 24 hours before the cell viability and mechanism measurements.

Propolis has been shown to reduce the level of blood glucose and suppress the histopathological changes in diabetics. However, it still remains unknown if propolis has a similar effect on diabetic retinopathy (DR). Our study aimed to evaluate the effect of the ethanol extract of Chinese propolis (EECP) on early DR in streptozotocin (STZ)-induced diabetic rats.

Secretions from mandibular glands (MGs) have important caste-specific functions that are associated with the social evolution of honey bees. To gain insights into the molecular architecture underlying these caste differences, we compared the gene expression patterns of MGs from queens, queenright workers (WQRs) and queenless workers (WQLs) using high-throughput RNA-sequencing technology. In total, we identified 46 candidate genes associated with caste-specific biosynthesis of fatty acid pheromones in the MG, including members of cytochrome P450 (CYP450) family and genes involved in fatty acid β-oxidation and ω-oxidation.

-10-hydroxy-2-decenoic acid (10-H2DA), 10-hydroxydecanoic acid (10-HDAA), and sebacic acid (SEA) are the three major fatty acids in royal jelly (RJ). Previous studies have revealed several pharmacological activities of 10-H2DA and 10-HDAA, although the anti-inflammatory effects and underlying mechanisms by which SEA acts are poorly understood. In the present study, we evaluated and compared the anti-inflammatory effects of these RJ fatty acids in lipopolysaccharide-stimulated RAW 264.

The aim of the present study was to investigate the clinical, pathological and molecular genetic characteristics of a pedigree with myotonic dystrophy type 1 (DM1). A series of clinical data from a pedigree with DM1 were collected. Muscle biopsy revealed a typical nuclear ingression within numerous muscle fibers following hematoxylin and eosin staining.

Article Synopsis
  • This study evaluates the efficacy and safety of sublingual immunotherapy (SLIT) in children aged 3-13 with allergies, specifically focusing on those as young as 3 years old.
  • The results showed that SLIT led to significant improvements in allergy symptoms, reduced asthma medication usage, and increased specific IgG4 levels, with no severe adverse events reported.
  • Both younger (under 5) and older children did not show differences in treatment outcomes, indicating SLIT is equally effective across this age range.

Objective: To determine the impact of passive smoking and the protective effect of antioxidants such as vitamin E and quercetin on learning and memory ability of mouse offsprings.

Methods: A passive smoking model of pregnant mice was established. Learning and memory ability was evaluated by the water maze test and long term potentiation (LTP).
