Therapeutic Effects of Tea Polyphenols on Renal Damage Induced by High Uric Acid.

Background: Hyperuricemia (HUA) is a condition characterized by excessive uric acid production and/or inadequate uric acid excretion due to abnormal purine metabolism in the human body. Uric acid deposits resulting from HUA can lead to complications such as renal damage. Currently, drugs used to treat HUA lack specificity and often come with specific toxic side effects.

Sustainable aviation fuel (SAF) from lignin: Pathways, catalysts, and challenges.

The aviation industry plays a crucial role in global trade and cultural exchange, but it faces significant challenges due to high production cost and environmental impacts. To achieve carbon neutrality, promoting the development of sustainable aviation fuel (SAF) is essential, with projections indicating that 65% of emissions reductions in the aviation industry by 2050 will come from the use of SAF. Lignin, as an abundant renewable resource, has great potential for conversion into aviation fuel components.

Transcranial alternating current stimulation inhibits ferroptosis and promotes functional recovery in spinal cord injury via the cGMP-PKG signalling pathway.

Aims: This study explores the potential of neuromodulation, specifically transcranial alternating current stimulation (tACS), as a promising rehabilitative therapy in spinal cord injury (SCI).

Main Methods: By meticulously optimizing treatment parameters and durations, our objective was to enhance nerve regeneration and facilitate functional recovery. To assess the efficacy of tACS, our experiments used the rat T10 SCI model.

Capture of Totipotency in Mouse Embryonic Stem Cells in the Absence of Pdzk1.

Totipotent cells can differentiate into three lineages: the epiblast, primitive endoderm, and trophectoderm. Naturally, only early fertilized embryos possess totipotency, and they lose this ability as they develop. The expansion of stem cell differentiation potential has been a hot topic in developmental biology for years, particularly with respect to the generation totipotent-like stem cells.
