Postoperative delirium after cardiac surgery associated with perioperative gut microbiota dysbiosis: Evidence from human and antibiotic-treated mouse model.

Background: Research links gut microbiota to postoperative delirium (POD) through the gut-brain axis. However, changes in gut microbiota and fecal short-chain fatty acids (SCFAs) in POD patients during the perioperative period and their association with POD are unclear.

Methods: We conducted a nested case-control study among patients undergoing off-pump coronary artery bypass grafting, focusing on POD as the main outcome.

Computed tomography-based nomogram for estimating progression-free survival probability in bladder cancer patients undergoing partial cystectomy.

Purpose: To establish a prognostic model to estimate progression-free survival (PFS) probability in bladder cancer (BCa) patients undergoing partial cystectomy.

Material And Methods: Consecutive patients who underwent partial cystectomy between August 2012 and April 2021 were enrolled. The primary endpoint was PFS during the follow-up.

Anti-Neuroinflammatory Effects of Prenylated Indole Alkaloids from the Antarctic Fungus sp. Strain SF-7367.

Inflammation has always been considered a trigger or consequence of neurodegenerative diseases, and the inhibition of inflammation in the central nervous system can effectively protect nerve cells. Several studies have indicated that various natural products inhibit neuroinflammation. Among these, Antarctic fungal metabolites have pharmacological activities and a developmental value.

Regulatory and retrograde signaling networks in the chlorophyll biosynthetic pathway.

Plants, algae and photosynthetic bacteria convert light into chemical energy by means of photosynthesis, thus providing food and energy for most organisms on Earth. Photosynthetic pigments, including chlorophylls (Chls) and carotenoids, are essential components that absorb the light energy necessary to drive electron transport in photosynthesis. The biosynthesis of Chl shares several steps in common with the biosynthesis of other tetrapyrroles, including siroheme, heme and phycobilins.

Inhibitory Effects of Compounds Isolated from L. (Noni) Seeds against Particulate Matter-Induced Injury.

L. (noni) is native to the tropical and semitropical areas and has been commercially available in health food stores and chain grocery stores specializing in natural foods, recently. Noni seeds are discarded as waste products through the industrial production of noni juice even though their bioactivity components might be a potential source of functional foods.
