Article Abstract

Infertility affects a growing number of families worldwide. Male factors contribute to 20-50% of infertility cases, and their improvement can help reduce the rising infertility rates. Recent studies have increasingly shown that fatty acids (FAs) can modulate sperm quality and significantly impact male fertility. This review investigates recent studies on the role of FAs in infertility, including their impact on sperm quality, FA profiles in infertility-related conditions, and the therapeutic potential of dietary and supplemental FAs. Our review reveals that omega-3 polyunsaturated fatty acids (PUFAs) are crucial for spermatogenesis and sperm function, and their imbalance with omega-6 PUFAs is associated with oxidative stress. FA metabolism is a promising target for infertility management. Precision nutrition strategies may complement conventional therapies, but further RCTs are needed to standardize protocols.

Post-traumatic osteoarthritis (PTOA) is a degenerative joint disease triggered by trauma or intense mechanical stress, leading to joint cartilage degeneration and functional impairment. Prostaglandin E2 (PGE2) contributes significantly to cartilage degradation following mechanical injury by activating its receptor, Prostaglandin E receptor 4 (EP4), on chondrocyte membranes. The homeostasis of articular cartilage primarily relies on the dynamic balance between cartilage degradation and repair, a process finely regulated by chondrocytes.

The family , encompassing the genus and related taxa, comprises diverse Gram-negative, aerobic, rod-shaped bacteria found in varied habitats, including air, soil, water and glaciers. Recent genomic-based taxonomic revisions have reclassified some species into new genera, such as and , due to polyphyletic relationships within the family . Certain species are known for forming biofilms or functioning as aerobic anoxygenic phototrophic bacteria, traits that enhance resilience in extreme environments like the cryosphere.

Five bacterial strains, designated as RCAD1438, RCAD1439, RCAD1670, RCAD1671 and RCAD1672, were isolated from the upper respiratory tract of ducks in Anhui, Shaanxi and Sichuan, China. All strains are Gram-stain-negative, rod-shaped, non-motile, non-spore-forming, aerobic and capsulated. They grow optimally at 37 °C and pH 7.
