British Journal of Pharmacology, EarlyView.Background and Purpose Hypoxic pulmonary hypertension (HPH) is a chronic disorder marked by irreversible pulmonary vascular remodelling (PVR) and pulmonary artery smooth muscle cell (PASMC) dysfunction. Astragaloside IV (AS‐IV), a natural saponin from Astragalus, shows potential in HPH management. This study explores AS‐IV's protective effect on PVR in

The Contractile Vacuole and Related Structures in Tetrahymena pyriformis* [PDF]
The Journal of Protozoology, 1964 SYNOPSIS. The nephridial system of T. pyriformis consists of a contractile vacuole with its two pores and an elaborate network of tubules. Both the vacuole and its tubules constitute a continuous system of single membranes of approximately 70 Å in thickness. Tubular fibrils of about 250 Å extend from the pore wall to the vacuole membrane and appear to

Journal of Eukaryotic Microbiology, Volume 72, Issue 6, November/December 2025.ABSTRACT While oxygen is essential for metabolic processes, many ciliate species thrive in low‐oxygen or even oxygen‐free environments. Anaerobic ciliates have adapted to a broad range of such habitats, yet have long remained understudied compared to their aerobic counterparts.

Fluid mechanics within mycorrhizal networks: exploring concepts, traits, and methodologies
New Phytologist, Volume 248, Issue 3, Page 1180-1191, November 2025.Summary Mycorrhizal fungi form hyphal networks for water and solute transport between soil and plant roots. Trait‐based research on these organisms typically focuses on spores and resource exchange structures within plant roots, but researchers have explored extraradical networks, the larger part of these organisms, much less.
