In addition to imperiling an individual's daily life, spinal cord injury (SCI), a catastrophic medical damage, can permanently impair an individual's body function. Methylprednisolone (MP), a medically accepted therapeutic drug for SCI, is highly controversial for the lack of consensus on its true therapeutic effect. In recent years, curcumin has served as a potential and novel therapeutic drug in SCI. Our study was intended to investigate the precise effect of MP and curcumin in SCI. We examined the function of MP and curcumin in a SCI model rat, both in vivo and in vitro, and found that there was a momentous improvement in Basso-Beattie-Bresnahan (BBB) scores in the MP-treated group when compared to Cur-treated group within 14 days...

Genomic mosaicism in parental gametes and peripheral tissues is an important consideration for genetic counseling. We studied a Chinese cohort affected by a severe epileptic disorder, Dravet syndrome (DS). There were 56 fathers who donated semen and 15 parents who donated multiple peripheral tissue samples. We used an ultra-sensitive quantification method, micro-droplet digital PCR (mDDPCR), to detect parental mosaicism of the proband's pathogenic mutation in SCN1A, the causal gene of DS in 112 families. Ten of the 56 paternal sperm samples were found to exhibit mosaicism of the proband's mutations, with mutant allelic fractions (MAFs) ranging from 0...

Galloylated plant specialized metabolites play important roles in plant-environment interactions as well as the promotion of human and animal health. The galloylation reactions are mediated by the formation of galloylglucose esters from gallic acid and UDP-glucose, catalyzed by the plant UGT84 family glycosyltransferases. To explore and exploit the structural determinants of UGT84 activities, we performed homology modeling and substrate docking of PgUGT84A23, a galloylglucose ester-forming family 84 UGT, as well as sequence comparisons of PgUGT84A23 with other functionally characterized plant UGTs...

Animals rely on complex signaling network to mobilize its energy stores during starvation. We have previously shown that the sugar-responsive TGFβ/Activin pathway, activated through the TGFβ ligand Dawdle, plays a central role in shaping the post-prandial digestive competence in the Drosophila midgut. Nevertheless, little is known about the TGFβ/Activin signaling in sugar metabolism beyond the midgut. Here, we address the importance of Dawdle (Daw) after carbohydrate ingestion. We found that Daw expression is coupled to dietary glucose through the evolutionarily conserved Mio-Mlx transcriptional complex...

The histone deacetylase inhibitor (HDACi) and tumor suppressor play an important role in genome reorganization and epigenetic regulation. In this study, granulosa cells (GCs) isolated from sika deer ovaries were cultured and treated with different concentrations of trichostatin A (TSA) for 48 h. It was found that TSA inhibited GCs proliferation and induced GCs apoptosis by upregulating expression of BAX, meanwhile, downregulating expression of GLUT3, GLUT8, BCL-XL. In addition, TSA caused cell cycle arrest at the G1 and G2/M phase accompanied by reducing expression of Cyclin D2 and CDK4...

The vast majority of Hg(2+) can be removed while elemental mercury (Hg(0)) can hardly be removed due to its characteristic of high volatility and insolubility in water. Till now, how to oxidize Hg(0) to Hg(2+) is the key for the purification of Hg(0), especially when there are others pollutants, such as HCl, SO2, and NOx. In this review, the method and mechanism of Hg(0) purification from flue gas by H2O2, KMnO4, NaClO2, and O3 are reviewed comprehensively. It is concluded that the oxidation of Hg(0) mainly depends on the electronic supply efficiency from the solution...
