Cerebral ischemia-reperfusion (I-R) is a complex pathological process. Although autophagy can be evoked by ischemia, its involvement in the reperfusion phase after ischemia and its contribution to the fate of neurons remains largely unknown. In the present investigation, we found that autophagy was activated in the reperfusion phase, as revealed in both(More)
The inner ear, which contains sensory organs specialized for hearing and balance, develops from an ectodermal placode that invaginates lateral to hindbrain rhombomeres (r) 5-6 to form the otic vesicle. Under the influence of signals from intra- and extraotic sources, the vesicle is molecularly patterned and undergoes morphogenesis and cell-type(More)
The inner ear epithelium, with its complex array of sensory, non-sensory, and neuronal cell types necessary for hearing and balance, is derived from a thickened patch of head ectoderm called the otic placode. Mouse embryos lacking both Fgf3 and Fgf10 fail to initiate inner ear development because appropriate patterns of gene expression fail to be specified(More)
To efficiently utilize rice straw and lessen its disposal problem on the environment, a lactic acid bacteria community, SFC-2 was developed from natural fermentation products of rice straw by continuous enrichment with the MRS-S broth (MRS broth with sucrose), and used to accelerate the fermentation of air-dried straws. The SFC-2 could rapidly lower the pH(More)
The levels of fibroblast growth factor (FGF) signaling play important roles in coordinating development of the mouse inner, middle, and outer ears. Extracellular signal-regulated kinases (ERKs) are among the effectors that transduce the FGF signal to the nucleus and other cellular compartments. Attenuation of ERK activity by dephosphorylation is necessary(More)
The effects of sulfuric acid, acetic acid, aqueous ammonia, sodium hydroxide, and steam explosion pretreatments of corn stalk on organic acid production by a microbial consortium, MC1, were determined. Steam explosion resulted in a substrate that was most favorable for microbial growth and organic acid productions. The total amounts of organic acids(More)
Subtle genetic variants in ion-channel genes might be at the origin of less rare forms of hypertension in the general population. To test this hypothesis, we observed the role of several important polymorphisms (T1155547C at exon7, G1155942T at exon8, G1156666A at intron10, and C1163527T at intron14) of WNK4 (with-no-kinase) gene on the prevalence of(More)
The role of the histamine H3 receptor (H3R) in cerebral ischaemia/reperfusion (I/R) injury remains unknown. Here we show that H3R expression is upregulated after I/R in two mouse models. H3R antagonists and H3R knockout attenuate I/R injury, which is reversed by an H3R-selective agonist. Interestingly, H1R and H2R antagonists, a histidine decarboxylase(More)
Alfalfa is a kind of forage that is difficult to ensile for good quality. Therefore, inoculants are always used to enhance the preservation of alfalfa silage. Through continuous restricted subcultivation, a lactic acid bacteria community (Al2) was selected from well-fermented alfalfa silage, which sharply decreased the pH level and produced a large amount(More)
Artemisinin (ART) and its analogues, such as dihydroartesunate (DHA) and artesunate (ATS), are sesquiterpene lactones with anticancer activities. Transferrin (Tf) receptor is frequently overexpressed in cancer cells. In order to improve the delivery and the anticancer activity of ART and its analogues, adducts of Tf with ART, DHA or ATS were fabricated by(More)
