Effects of water level on three wetlands soil seed banks on the Tibetan Plateau. [PDF]

PLoS ONE, 2014
BACKGROUND: Although the effect of water level on germination in soil seed banks has been documented in many ecosystems, the mechanism is not fully understood, and to date no empirical studies on this subject exist.

Comprehensive In Vitro Profiling Demonstrates Successful Immune Evasion of Bioengineered Immune‐Shielded Heart Valves

Advanced Healthcare Materials, EarlyView.
Living donor heart valves offer superior durability for pediatric patients but trigger immune rejection. Lentiviral delivery of viral immune‐evasion genes US2 and Serpin b9 into donor valve cells and valve tissue suppresses HLA expression, reduces PBMC clustering and cytotoxic killing, and induces transcriptional immune‐tolerance programs, paving the ...

How are seed banks and seed rain affected after 30 years of exotic grass cultivation?

Rodriguésia
The conversion of different forest formations into pastures with exotic grasses leads to irreversible damage over time. However, the dispersal of diaspores from adjacent areas and the formation of seed banks can influence regeneration processes.
