Light mainly affects animal reproductive performance through the hypothalamus- pituitary-gonadal axis, but the specific regulating mechanism is not yet clear in duck. To reveal the effects of light on the laying performance of ducks and its possible regulatory mechanisms, Shanma ducks at 52 weeks age were divided into three group treated with different photoperiods of 16 hr (control group), 24 hr (long-photoperiod group, LP), and 8 hr (short-photoperiod group, SP). Laying performance, endocrine-related hormones and gene expression of three groups were compared.

Leydig cells were collected from 200-day-old mallard ducks and divided into five treatment groups (0, 50, 100, 200, and 400 ng/mL LPS). After treatment with LPS for 6, 12, 24, and 48 h, testosterone, activin, and inhibin levels in the cell supernatants were determined using enzyme-linked immunosorbent assay (ELISA) kits.

- Portal vein tumor thrombus is a common and complex issue in hepatocellular carcinoma, leading to poorer liver function and prognosis compared to those without it.
- Western and some Asian guidelines suggest that such patients receive only palliative care, like sorafenib, due to the severity of their condition.
- Recent studies highlight new treatment options and an evidence-based approach for managing these patients, though there is still no consensus on the best management policies.
