A High-Precision Identification Method for Maize Leaf Diseases and Pests Based on LFMNet under Complex Backgrounds.

Maize, as one of the most important crops in the world, faces severe challenges from various diseases and pests. The timely and accurate identification of maize leaf diseases and pests is of great significance for ensuring agricultural production. Currently, the identification of maize leaf diseases and pests faces two key challenges: (1) In the actual process of identifying leaf diseases and pests, complex backgrounds can interfere with the identification effect.

[Electroacupuncture Intervention Improves Cartilage Degeneration and Subchondral Bone Osteoporosis of Knee-joint Possibly by Adjusting OPG/RANK/RANKL Signaling in Ovariectomized Rats].

Objective: To observe the effect of electroacupuncture (EA) on histopathological changes of cartilage and subchondral bone and osteoprotegerin (OPG)，receptor activator of nuclear factor-κB (RANK), and RANK ligand (RANKL) (OPG/RANK/RANKL) signaling and the expression of matrix metalloproteinase-13 (MMP-13) in ovariectomized(OVX)rats, so as to explore its mechanism underlying improvement of osteoporosis.

Methods: Three-month female SD rats were randomly divided into sham operation, model and EA groups (＝8 in each group). The ovoariectomy model was established by resection of bilateral ovaries.
