Steroidal glycoalkaloids (SGAs) are specialized metabolites primarily produced by Solanaceae plants such as potatoes and tomatoes. Notably, α-solanine and α-chaconine are recognized as toxic substances in potatoes. While the biosynthetic pathways of SGAs are largely understood, the final steps of α-solanine and α-chaconine biosynthesis remained elusive.

Introduction: The manufacture of cell-based products requires assuring sterility through all processes, with aseptic processing in a cleanroom. The environment consists of a critical processing zone (CPZ) that can ensure a level of cleanliness that allows cell culture containers to be opened, and a support zone (SZ) adjacent to it and accessed by an operator. In this study, an environment for cell manufacturing was proposed by designing an air mass balance in an aseptic processing area (APA).

Background: Although anaplastic lymphoma kinase inhibitors (ALKis) are the effective initial treatment for patients with anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC), most patients experience resistance to ALKis, leading to the need for alternative therapies. Immune checkpoint inhibitors (ICIs) are a standard NSCLC treatment. On the other hand, their efficacy remains unclear for ALK-positive NSCLC.

The awn is a bristle-like appendage that protrudes from the seed tip and plays a critical role in preventing feed damage and spreading habitats in many grass species, including rice. While all wild species in the genus have awns, this trait has been eliminated in domesticated species due to its obstructive nature to agricultural processes. To date, several genes involved in awn development have been identified in wild rice, and which are ancestral species of cultivated rice in Asia and Africa, respectively.
