Controlling the microstructure of biomass-derived carbon is of essential importance for directing its use. Herein, a hollow spherical carbon (HSC) was prepared from corncob lignin through spray drying and the subsequent heat treatment. The HSC, which is characterized by the hierarchically porous structure, delivers high rate capability when it is directly used as the electrode material for supercapacitors. This strategy that uses lignin as the precursor avoids the intrinsic difficulty in tuning the micro-structure of the biomass-derived carbons and is suitable for mass production for practical use...

Ripostatin is a promising antibiotic that inhibits RNA polymerase by binding to a novel binding site. In this study, the characterization of the biosynthetic gene cluster of ripostatin, which is a peculiar polyketide synthase (PKS) hybrid cluster encoding cis- and trans-acyltransferase PKS genes, is reported. Moreover, an unprecedented mechanism for phenyl acetic acid formation and loading as a starter unit was discovered. This phenyl-C2 unit is derived from phenylpyruvate (phenyl-C3) and the mechanism described herein explains the mysterious loss of one carbon atom in ripostatin biosynthesis from the phenyl-C3 precursor...

Liver fibrosis is a chronic liver disease characterized by the proliferation and activation of hepatic stellate cells (HSCs) and excessive deposition of extracellular matrix (ECM). Research suggests that microRNAs (miRNAs) are a new type of regulator of liver fibrosis. In the present study, we investigated the role of microRNA-9 (miR-9) in the process of liver fibrosis, as well as the underlying mechanism of action. Downregulated levels of miR-9 were found in fibrotic liver tissues and activated HSCs as detected by qRT-PCR; whereas, expression of multidrug resistance‑associated protein 1 (MRP1/ABCC1) was upregulated in the fibrotic liver tissues and activated HSCs...

Diabetes mellitus (DM) is a chronic metabolic disease, where the predominant pathogenesis is pancreatic β‑cells dysfunction or injury. It has been well established that inflammation leads to a gradual exhaustion of pancreatic β‑cell function with decreased β‑cell mass likely resulting from pancreatic β‑cells apoptosis or death. Vitexin, a major bioactive flavonoid compound in plants has numerous pharmacological properties, including antioxidant, anti‑inflammatory and antimyeloperoxidase. Whether vitexin can protect pancreatic β‑cells against lipopolysaccharide (LPS)‑induced pro‑inflammatory cytokine production and apoptosis has received little attention...

Downregulation of miR-133b has been reported in multiple types of malignancies including colorectal cancer (CRC). We previously confirmed that TAp63 actively translates microRNA-133b (miR-133b) transcripts. While the presence of miRNA mutations have frequently been described in CRC, most CRCs do not show any variation in the miR‑133b coding sequence. Therefore, it is important to elucidate the relationship between TAp63 and miR-133b, and identify other mediators of miR-133b downregulation in CRC. The expression of TAp63 was detected by RT-qPCR, western blotting, immunohistochemistry (IHC) and densitometric analysis using Image-Pro Plus 6...

Primary dysmenorrhea (PD) is a common gynecological disorder which, while not life‑threatening, severely affects the quality of life of women. Most patients with PD suffer ovarian hormone imbalances caused by uterine contraction, which results in dysmenorrhea. PD patients may also suffer from increases in estrogen levels caused by increased levels of prostaglandin synthesis and release during luteal regression and early menstruation. Although PD pathogenesis has been previously reported on, these studies only examined the menstrual period and neglected the importance of the luteal regression stage...
