Gallbladder bile of the bullfrog, R a m catesbezana was found to contain a number of minor bile acids and bile alcohols in unconjugated forms. The following bile acids and bile alcohols were identified by combined gas-liquid chromatography-mass spectrometry: cholic acid, allocholic acid, 3a,7a, 12a-trihydroxy-5a-cholestan-26-oic acid, 3a,7a, 12atrihydroxy-24-methyl-5~-cholestan-26-oic acid, 3a,...

Ethanol enhancement of 5-hydroxytryptamine (5-HT)(3A) receptor-mediated responses may have important consequences in the intoxicating and addictive properties of ethanol. Although the exact mechanism is unknown, ethanol-mediated enhancement of 5-HT(3) receptor current has been proposed to occur due to stabilization of the open-channel state. It has not been possible to directly measure the open...

In this study, hMex-3A was selected from TCGA database as a research object to observe the effects of small interfering RNA (siRNA) targeting hMex-3A on the biological activities of human bladder cancer and explore its mechanism for the first time. In this study, there were 2 groups including negative control group and hMex-3A-siRNA-transfected cells group for 5637 and T24 cell lines, respectiv...

The Brn-3a transcription factor stimulates the expression of the anti-apoptotic Bcl-2 and Bcl-x proteins and protects neuronal cells from apoptosis. Here we show that a minimal Bcl-x promoter is activated by Brn-3a and that this stimulation is prevented by the pro-apoptotic p53 protein. Both these effects are mediated via Bcl-x promoter sequences, which are indistinguishable from those required...

RNA-binding proteins (RBPs) play essential roles in RNA metabolism, regulating RNA splicing, transport, surveillance, decay and translation. The aberrant expression of RBPs leads to gene expression alteration and frequently causes various diseases, such as cancer. In this study, we are the first to provide evidence that hMex-3A, a RBP that belongs...

Nanodisks (ND) are ternary complexes of phospholipid, one or more hydrophobic bioactive agents and an apolipoprotein scaffold. These nanoscale assemblies are organized as a disk-shaped lipid bilayer whose perimeter is stabilized by an apolipoprotein scaffold. Solubilization of hydrophobic bioactive agents is achieved by their integration into the ND lipid milieu. When the cis-imidazoline, nutli...

The detailed organization of somatosensory area 3a was examined in macaque monkeys using multiunit electrophysiological recording techniques. By examining topographic relationships, changes in receptive field size, and the type of stimulus that neurons responded to, functional boundaries of area 3a were determined and related to architectonic boundaries. One striking observation was that the lo...

The 3A non-structural protein of foot-and-mouth disease viruses is a relatively conserved protein comprising 153 amino acids. Recent studies have demonstrated correlation between mutations in the 3A non-structural-protein-coding region, including a 10-amino acid deletion, and attenuation of the viruses in cattle. Although the 3A coding region of several type A, O and C isolates has previously b...

Phthaloylimidoalkyl derivatives (1a, 1b) were treated with isopropylamine to give 3-benzamido-1-(4-(2-methoxyphenyl)piperazin-1-yl)]propyl-2-isopropyl carboxamide (3a) and 4-benzamido-1-(4-(2-methoxyphenyl)piperazin-1-yl)butyl-2-isopropyl carboxamide (3b). The compounds were unequivocally characterized by IR, NMR and MS spectra and elemental analysis. Carrageenan-induced rat paw assay was used ...

There are few systematic comparisons of Etymotic ER-3A insert earphones versus supra-aural earphones in auditory brainstem response (ABR) measurement. We compared ER-3A insert earphones and two types of supra-aural earphones (TDH-39P and TDH-49P) in a group of normal hearing adults. Acoustic analyses revealed spectral and temporal differences among earphones. Behavioral and ABR thresholds to cl...
