This study aimed to establish a liver cancer model of qi deficiency through the swimming exhaustion and xenograft of human hepatoma HepG2 cells.

Near-infrared target enhanced peripheral clearance of amyloid-β in Alzheimer's disease model.

Clearance of peripheral amyloid-β (Aβ) has been demonstrated particularly promising for overcoming the blood-brain barrier (BBB) hurdle to remove brain-derived Aβ associated with Alzheimer's disease (AD). However, currently used therapeutic agents targeting peripheral Aβ cannot simultaneously achieve plasma Aβ enrichment and enhanced clearance, which may result in poor bioavailability and rather low efficacy. Moreover, most of therapeutic agents usually promote the unfavorable aggregation of Aβ.

Poria cocos could ameliorate cognitive dysfunction in APP/PS1 mice by restoring imbalance of Aβ production and clearance and gut microbiota dysbiosis.

Alzheimer's disease (AD) is the most common neurodegenerative disorder. Amyloid beta-protein (Aβ) plaques, which are the hallmark of AD, are formed from the imbalance of Aβ production and clearance accompanied by neuroinflammation, gut dysbiosis, and metabolite dysfunction. All of these processes give rise to neurochemical deficiencies and synaptic dysfunction, which ultimately contribute to recognition dysfunction.

Stable isotope labeling derivatization combined with multiple-mass spectrometry technologies to monitor metabolites of tenuifoliside A incubated with intestinal bacteria incubation model.

Aromatic carboxylic acids (ACAs), play important roles in preventive and therapeutic effects for some diseases. However, complex matrix effect and poor detection sensitivity make it difficult and even rare to detect ACAs in complex bio-samples. Herein, a stable isotope labeling derivatization (SILD) method based on one-pot synthesis of carboxylic amides by aniline (AN) and aniline-d (AN-d) was firstly designed for quantitatively monitoring ACAs under mild conditions.
