We consider the nonlocal Hénon-Gelfand–Liouville problem $$\begin{aligned} (-\Delta )^s u = |x|^a e^u\quad \mathrm {in}\quad \mathbb {R}^n, \end{aligned}$$ for every $$s\in (0,1)$$ , $$a>0$$ and $$n>2s$$ . prove a monotonicity formula solutions of above equation using rescaling arguments. apply this together with blow-down analysis arguments technical integral estimates to establish non-existen...

Three stereoisomeric inhibitors of Pin1: (2R,5S)-, (2S,5R)- and (2S,5S)-Ac-pSer-Ψ[(Z)CH = C]-pipecolyl(Pip)-2-(2-naphthyl)ethylamine 1, that mimic L-pSer-D-Pro, D-pSer-L-Pro, and D-pSer-D-Pro amides respectively, were synthesized by a 13-step route. The newly formed stereogenic centers in the pipecolyl ring were introduced by Luche reduction, followed by stereospecific [2,3]-Still-Wittig rearra...

The NMR solution structures at different levels of refinement of three different 2 S albumin seed proteins, the recombinant pronapin precursor from Brassica napus, the recombinant RicC3 from Ricinus communis and the methionine-rich protein from sunflower ( Helianthus annuus ), are described. The resulting common structure consists of a bundle of five alpha-helices, folded in a right-handed supe...

BACKGROUND (2S)-Pinocembrin is a chiral flavanone with versatile pharmacological and biological activities. Its health-promoting effects have spurred on research effects on the microbial production of (2S)-pinocembrin. However, an often-overlooked salient feature in the analysis of microbial (2S)-pinocembrin is its chirality. RESULTS Here, we presented a full characterization of absolute conf...

The contribution of proteases in the central vacuole of Chara corallina internodal cells to overall cellular protein degradation was examined. I measured the decrease in the trichloroacetic acid (TCA)-precipitable radioactivity in the cell for a 6-d chase period after labeling cellular proteins with [3H]leucine. The kinetics of [3H]leucine-labeled protein disappearance showed that the half-life...

To gain a better understanding of molecular and biochemical events involved in light intensity adaptations of Dunaliella salina, we studied the expression of phytoen synthase (psy) gene; pigments, carbohydrates, proteins and lipids accumulation under two light intensities. The cells were pre-cultured under 50 µmol photon m-2s-1 light intensity and then transferred to two different light intensi...

The potencies of kainate, glutamate and diastereomers of 4-methylglutamate were determined for activation and steady-state desensitization of GluR6 and dorsal root ganglion-type kainate receptors using whole-cell voltage clamp. In HEK293 cells expressing GluR6, all four diastereomers induced desensitizing inward currents at relatively high concentrations (> 50 microM), however, the 2S,4R diaste...

The distribution, clearance, and bioavailability of (2S,6S)-hydroxynorketamine has been studied in the Wistar rat. The plasma and brain tissue concentrations over time of (2S,6S)-hydroxynorketamine were determined after intravenous (20 mg/kg) and oral (20 mg/kg) administration of (2S,6S)-hydroxynorketamine (n = 3). After intravenous administration, the pharmacokinetic parameters were estimated ...
