Six previously unreported papulacandins, namely pestiorosins A-F (1-6), were isolated from the fermentation products of the fungus Pestalotiopsis rosea YNJ21 isolated from the fruitbody of Amanita exitialis. The structures of these compounds, along with a known compound called pestiocandin (7), were determined using MS, NMR data, and modified Mosher's method. All compounds exhibited significant antifungal activity against Candida albicans, with MIC values ranging from 0.

The circadian clock is an endogenous oscillator that is involved in controlling photoperiodic flowering. The rice LATE ELONGATED HYPOCOTYL (OsLHY), the core oscillator component of circadian clock, is a homolog of the LHY/CCA1 in Arabidopsis.

However, only a few have been discovered in rice up to now, and their activities are mostly induced by artificial treatments (e.g.

AsO was loaded via vapor deposition (As(vap)) and the wet impregnation (As(imp)) method, respectively. Results demonstrated that the poisoning extent of vapor arsenic was much stronger than in the liquid state.

Circular RNAs (circRNAs) are a new type of intracellular regulator that have been widely identified in animals and plants by high-throughput sequencing. However, there are still few functional studies on circRNAs in plants. To better understand maize circRNAs and their potential functions, we identified 1199 circRNAs in maize from RiboMinus RNA-Seq transcriptome data, and found distinct features of splicing site selection bias, longer flanking introns, and miniature inverted-repeat transposable element (MITE) insertions in flanking introns in maize circRNAs compared to other plant circRNAs.

Here, RNA-Seq was performed to investigate the expression profiles of young panicle from rice TGMS line at the microspore mother cell and meiosis stages under sterile and fertile conditions. A total of 1070 differentially expressed genes (DEGs) were identified, which were enriched in protein folding, protein binding, regulation of transcription, transcription factor activity and metabolic related processes.

In the present study, the effects of Scue on amyloid β (Aβ)-induced AD-like pathology were investigated. An model of inflammation and an aged rat model were used to confirm the effects of Scue.

It exhibits various therapeutic effects including neuroprotective, anti-oxidant, anti-inflammatory, and immunomodulatory activities. Angelica polysaccharides (APs), bioactive constituents of Angelica have been shown to be responsible for these effects; however, the utility of APs for the treatment of glioma and their mechanism of action remain to be elucidated.

Background/aims: Deoxyschizandrin as one of the most important component of Schisandra chinensis (Turcz.) Baill plays an immunomodulatory role in a variety of diseases, yet its role in ulcerative colitis remains to be elucidated. We aimed to investigate the role of deoxyschizandrin in DSS-induced ulcerative colitis in mice.

Oviductus Ranae is the dry oviducts of Rana temporaria chensinensis, and it has been reported to have a range of biological activities. This study aimed to investigate the effects of Oviductus Ranae protein hydrolysate (ORPH) on human glioma C6 cell proliferation and apoptosis in vitro and in vivo. Following in vitro treatment, cell viability and colony formation assays showed that ORPH inhibited C6 cell proliferation.

Long-acting BLM A(2)-PLGA microspheres were prepared using multiple emulsion solvent evaporation, and the related characteristics of the microspheres were investigated. The prepared microspheres were administered to dogs via intramuscular injection.
