Article Synopsis
  • The study focused on optimizing the extraction of polysaccharides from the stem barks and flowers of Magnolia officinalis, achieving maximum yields of 4.12% and 5.5%, respectively.
  • Three specific polysaccharides, MOBP-I, MOBP-II, and MOFP-I, were purified and characterized, revealing different molecular weights and sugar compositions through gas chromatography analysis.
  • The polysaccharides exhibited varying biological activities, with MOBP-I showing significant hypoglycemic effects, while MOBP-II and MOFP-I were more effective in reversing damage from UV radiation, highlighting the connection between their composition and bioactivity.

This study was sought to investigate the chemical composition and antibacterial and antiulcerative colitis (UC) effects of essential oil from Pruni Semen (PSEO). A GC-MS assay showed that the major compounds in PSEO were products of amygdalin hydrolysis, which possessed great antibacterial and anti-inflammatory potential. antibacterial experiments demonstrated that PSEO treatment inhibited activity of four kinds of intestinal pathogens probably by disrupting the cell wall.

Obesity is a significant public health problem worldwide that is characterized by abnormal or excessive fat accumulation. Unfortunately, the application of available weight-loss drugs has been restricted because of their serious adverse effects. Browning of white adipose tissue (WAT), which refers to the transformation of white adipocytes to beige adipocytes under certain stimulations, is regarded as a new strategy to solve the obesity problem.

Acne vulgaris is one of the most common inflammatory dermatoses in dermatological practice and can affect any gender or ethnic group. Although in previous studies, we had found that licorice flavonoids (LCF) play an anti-acne role by inhibiting PI3K-Akt signaling pathways and mitochondrial activity, the mechanism of LCF regulating skin metabolism, serum metabolism and skin microbes is still unclear. Here, we performed a full spectrum analysis of metabolites in the skin and serum using UHPLC-Triple TOF-MS.

Article Synopsis
  • - Neuroblastoma (NB) is the most common solid tumor in children and originates from neural-crest-derived cells, but its developmental origins are still not well understood.
  • - The study utilizes single-cell RNA sequencing to analyze the gene expression of nearly 161,000 NB tumor cells from 16 patients and 12,103 developmental cells from human embryos and fetal adrenal glands.
  • - The results reveal that adrenal NB tumor cells largely resemble noradrenergic chromaffin cells, suggesting that the progression of NB reflects the growth and differentiation patterns of these normal cells during development.

Depression is a widespread psychological disorder that affects up to 20% of the world's population. Traditional Chinese medicine (TCM), with its unique curative effect in depression treatment, is gaining increasing attention as the discovery of novel antidepressant drug has become the pursuit of pharmaceutical. This article summarizes the work done on the natural products from TCM that have been reported to conceive antidepressant effects in the past two decades, which can be classified according to various mechanisms including increasing synaptic concentrations of monoamines, alleviating the hypothalamic-pituitary-adrenal (HPA) axis dysfunctions, lightening the impairment of neuroplasticity, fighting towards immune and inflammatory dysregulation.
