Exploring the Allelic Diversity of the Self-Incompatibility Gene Across Natural Populations in Petunia (Solanaceae).

Self-incompatibility (SI) is a genetic mechanism to prevent self-fertilization and thereby promote outcrossing in hermaphroditic plant species through discrimination of self and nonself-pollen by pistils. In many SI systems, recognition between pollen and pistils is controlled by a single multiallelic locus (called the S-locus), in which multiple alleles (called S-alleles) are segregating. Because of the extreme level of polymorphism of the S-locus, identification of S-alleles has been a major issue in many SI studies for decades.

Right Posterior Segment Graft in Adult Living-Donor Liver Transplantation: A Report of 17 Years of Experience at a Single Institution.

Objectives: The right posterior segment graft can be selected in cases where neither the right nor left lobe graft satisfies the selection criteria for adult living donor liver transplant. However, vascular and biliary anatomy may cause technical difficulties in procurement of posterior segments in donors of living donor liver transplant and may require specific attention in vascular and biliary reconstruction in the recipient. In this study, we examined the feasibility of right posterior segment grafts in adult living donor liver transplants through donor safety and recipient outcomes and clarified the anatomic points of the surgical technique.

Neural Crest-Derived Mesenchymal Cells Support Thymic Reconstitution After Lethal Irradiation.

Reconstitution of the thymus is essential for assessing thymic function following injury. However, the currently employed cytoreductive regimes unvaryingly affect the thymic microenvironment, thereby impeding the recovery of T lymphopoiesis. The thymic stroma is composed of epithelial and mesenchymal cells.

The intron binding protein EMB-4 is an opposite regulator of cold and high temperature tolerance in .

Adaptation and tolerance to changes in heat and cold temperature are essential for survival and proliferation in plants and animals. However, there is no clear information regarding the common molecules between animals and plants. In this study, we found that heat, and cold tolerance of the nematode is oppositely regulated by the RNA-binding protein EMB-4, whose plant homolog contains polymorphism causing heat tolerance diversity.

Donor Complications Following Living Donor Hepatectomy: 17-Year Experience of a Single Team in One Institution of Japan.

Objectives: Donor safety is paramount in living donor liver transplantation. However, there remains a risk of postoperative complications for some donors. Here, we provide a comprehensive assessment of donor morbidity by a single team with 17 years of experience at a single center.
