Hyperuricemia (HUA) is a globally prevalent metabolic disease characterized by excessive production or insufficient excretion of uric acid in the serum. Although several drugs are available for the treatment of HUA, they have been associated with undesirable side effects. Therefore, this study aims to evaluate the therapeutic effects of sunflower head extract (KHE) on HUA in a mouse model and explore its potential mechanisms. All mice were randomly divided into three groups: Normal control (NC, 0.5% CMC-Na), HUA model (MD, yeast extract paste 20 g/kg), and KHE treatment group (KHE, 1 g/kg). Biochemical indicators, the oxidative stress state, and metabolomics were analyzed. KHE reduced the levels of 5-aminoimidazole ribonucleotide, xanthine, hypoxanthine, and uric acid in the serum of mice with HUA but increased the levels of adenine and taurine. KHE decreased the activities of superoxide dismutase (SOD) enzymes, the hepatic hydrogen peroxide (HO) and malondialdehyde (MDA) levels, and the serum levels of betaine aldehyde and beta-D-glucosamine. KHE improved oxidative stress levels and mitigated potential damage to the kidneys and joints caused by urate deposition. These findings provide comprehensive evidence supporting the anti-HUA effects and underlying mechanisms of KHE in HUA mice.

Prediction of crop yield is essential for decision-makers to ensure food security and provides valuable information to farmers about factors affecting high yields. This research aimed to predict sunflower grain yield under normal and salinity stress conditions using three modeling techniques: artificial neural networks (ANN), adaptive neuro-fuzzy inference system (ANFIS), and gene expression programming (GEP). A pot experiment was conducted with 96 inbred sunflower lines (generation six) derived from crossing two parent lines, over a single growing season.

Background: Several cancer therapies are being developed, and given the variability of different cancer types, the goal of these therapies is to remove the invasive tumor from the body, kill the cancer cells, or else retard the growth. These include chemotherapeutic agents and targeted therapy using small molecules and antibodies. However, antibodies can generate an immune response upon repeated administration, and producing antibodies could be expensive.

Nanoparticles play a significant role in enhancing crop yield and reducing nutrient loss through precise nutrient delivery mechanisms. However, it is imperative to ascertain the specific plant physiology altered by these nanoparticles. This study investigates the effects of green-synthesized nanoparticles, specifically boron nitride and sulphur, on sunflower yield, seed quality, and physiological activities.

Insects provide important pollination services for cops. While land use intensification has resulted in steep declines of wild pollinator diversity across agricultural landscapes, releasing managed honeybees has been proposed as a countermeasure. However, it remains uncertain whether managed honeybees can close the pollination gap of sunflower (Helianthus annuus L.
