Exploring Research Trends and Mechanisms: Maternal Diabetes and Neural Tube Defects (1991-2023).

Background: Neural tube defect (NTD) is the second most common congenital neuropathy in the world. Maternal diabetes is an important factor leading to the occurrence of NTD in offspring. However, existing studies lack a systematic analysis of the correlation between maternal diabetes and NTDs, as well as an exploration of NTD pathogenesis and associated preventive strategies.

However, as many tumors are resistant to current immune checkpoint inhibitors, the discovery of novel immune checkpoints could facilitate the development of additional immunotherapeutic strategies to improve patient responses. Here, we identified increased expression of the adhesion molecule immunoglobulin superfamily member 9 (IGSF9) in tumor cells and tumor-infiltrating immune cells across multiple cancer types.

Flying squirrels use a mortise-tenon structure to fix nuts on understory twigs.

Squirrels of temperate zones commonly store nuts or seeds under leaf litter, in hollow logs, or even in holes in the ground; however, in the humid rainforests of Jianfengling in Hainan, South China, we show that some flying squirrels cache elliptical or oblate nuts by hanging them securely in vegetation. These small flying squirrels were identified as (G. M.
