Gastrointestinal (GI) involvement in Lewy body diseases (LBDs) has been observed since the initial descriptions of patients by James Parkinson. Recent experimental and human observational studies raise the possibility that pathogenic alpha-synuclein (⍺-syn) might develop in the GI tract and subsequently spread to susceptible brain regions. The cellular and mechanistic origins of ⍺-syn propagation in disease are under intense investigation.

Lung progenitor (LP) cells identified by the expression of transcription factor NK2 homeobox 1 (NKX2.1) are essential for development of all lung epithelial cell types and hold tremendous potential for pulmonary research and translational regenerative medicine applications. Here we present engineered hydrogels as a promising alternative to the naturally derived materials that are often used to differentiate human induced pluripotent stem cells (iPSCs) into LP cells.

Mesenchymal stem cell (MSC) therapy has emerged as a promising approach for addressing various eye-related conditions. Yet, its clinical application faces challenges due to issues such as limited biocompatibility and difficulties in effectively delivering treatment to specific ocular tissues. Recent studies have shifted attention towards MSC-derived exosomes, which share similar regenerative, reparative, and immunomodulatory capabilities with their origin cells.

Background And Objectives: Accurate intraoperative assessment of coronal alignment is critical to achieving favorable clinical outcomes in adult spinal deformity surgery. However, surgical positioning creates challenges in predicting standing coronal alignment. Gravity-based plumblines require an upright posture and are not possible intraoperatively.

Seed color is a critical quality trait in numerous plant species. In oilseed crops, including rapeseed and mustard, yellow seeds are distinguished by their significantly higher oil content and faster germination rates compared to black or brown counterparts. Despite the agronomic significance of the yellow seeds being a prime breeding target, the mechanisms underlying elevated oil content remain obscure.
