Development of pollinated and unpollinated ovules in Ginkgo biloba: unravelling the role of pollen in ovule tissue maturation.

In gymnosperms such as Ginkgo biloba, the arrival of pollen plays a key role in ovule development, before fertilization occurs. Accordingly, G. biloba female plants geographically isolated from male plants abort all their ovules after the pollination drop emission, which is the event that allows the ovule to capture pollen grains.

Isolated axial lateropulsion caused by an acute lateral medullary infarction involving the dorsal spinocerebellar tract: A case report.

Lateral medullary syndrome encompasses a broad spectrum of symptoms and signs depending on the bulbar localization of the lesion. Body lateropulsion (BL) can occur without vestibular and cerebellar symptoms, as a unique manifestation of a lateral medullary infarction. However, it is relatively rare and challenging to diagnose.

Identification of key regulatory genes involved in the sporophyte and gametophyte development in Ginkgo biloba ovules revealed by in situ expression analyses.

Premise: In Arabidopsis thaliana, the role of the most important key genes that regulate ovule development is widely known. In nonmodel species, and especially in gymnosperms, the ovule developmental processes are still quite obscure. In this study, we describe the putative roles of Ginkgo biloba orthologs of regulatory genes during ovule development.

The role of pollination in controlling Ginkgo biloba ovule development.

Generally, in gymnosperms, pollination and fertilization events are temporally separated and the developmental processes leading the switch from ovule integument into seed coat are still unknown. The single ovule integument of Ginkgo biloba acquires the typical characteristics of the seed coat long before the fertilization event. In this study, we investigated whether pollination triggers the transformation of the ovule integument into the seed coat.

Crosstalk between Macrophages and Myxoid Liposarcoma Cells Increases Spreading and Invasiveness of Tumor Cells.

Myxoid liposarcoma (MLPS) is the second most common subtype of liposarcoma and has tendency to metastasize to soft tissues. To date, the mechanisms of invasion and metastasis of MLPS remain unclear, and new therapeutic strategies that improve patients' outcomes are expected. In this study, we analyzed by immunohistochemistry the immune cellular components and microvessel density in tumor tissues from patients affected by MLPS.
