Rapid Identification of Alien Chromosome Fragments and Tracing of Bioactive Compound Genes in Intergeneric Hybrid Offspring Between and Based on AMAC Method.

Distant hybridization between and related genera serves as an effective approach for rapeseed germplasm innovation. , a wild relative of , has emerged as a valuable genetic resource for rapeseed improvement due to its medicinal properties. This study employed anchor mapping of alien chromosomal fragment localization (AMAC) method to efficiently identify alien chromosomal fragments in the progeny derived from distant hybridization between and , 'Songyou No.

Case report: Ultrasound-guided intrauterine biopsy and RF ablation therapy for fetal posterior neck solid tumor: first successful report.

Large fetal head and neck tumors are being increasingly identified during prenatal examination and tend to have a poor prognosis. Nevertheless, appropriate intrauterine interventions at suitable periods can improve pregnancy outcome. Ultrasound-guided puncture biopsy of the solid fetal head and neck mass and radiofrequency ablation of a portion of the tissue can clarify the tumor pathology and reduce the tumor size, respectively.
