Raman spectroscopy using a hot stage indicates that the intercalation of hexacyanoferrate(II) and (III) in the interlayer space of a Mg, Al hydrotalcites leads to layered solids where the intercalated species is both hexacyanoferrate(II) and (III). Raman spectroscopy shows that depending on the ...

In the course of the last years hexacyanoferrates have been widely studied; even though, the adsorption properties of Zn (II) hexacyanoferrate(II) (labelled here Zn-HII) have not been thoroughly considered. In addition, soft porous crystals, i.e., adsorbents that display structural flexibility h...

Concerning decontamination of a radioactive liquid waste which includes seawater and nuclides from irradiated fuels and activated materials, the in-situ generation of metal hexacyanoferrates(II) by adding potassium hexacyanoferrate(II) and codecontamination of 134,137Cs and some activation produ...

In the ultrasonic wave from 20–70 kHz, nanosized copper hexacyanoferrate(II) materials were synthesized by the reaction of copper sulfate and potassium ferrocyanide(II) and at room temperature, respectively, and 323 K. The sensors based on nanosized copper hexacyanoferrate(II) were fabricated i...

The oxidation of kappa‑carrageenan (KCAR) as sulfated anionic polyelectrolyte by alkaline hexacyanoferrate(III) has been investigated spectrophotometrically. Pseudo-first-order plots showed complex kinetics where slightly upward curvatures at the initial absorbance changes were appeared, followe...

Electrical conductivities of tetramethylammonium hexacyanoferrate(III), tetraethylammonium hexacyanoferrate(III) and benzyltrimethylammonium hexacyanoferrate(III) in dilute aqueous solutions, in the 278.15 K to 313.15 K temperature range are reported. These conductivities are examined in terms o...

Administration of cholesterol-4-14C to Podocarpus macrophyllus seedlings resulted in the formation of the insect-metamorphosing substances ponasterone A and ecdysterone in radioactive form.

The apolar ecdysterold present in the developing embryo of the blue crab, Callinectes sapidus Rathbun, is tentatively identified as ponasterone A C 2β,3β,14α20,22-pentahydroxy-50-cholest-7-en-6-one) on the basis of Chromatographic, immunological and mass spectral evidence. The apolar ecdyster...

Ecdysone agonists, including dibenzoylhydrazines, significantly inhibited the binding of [3H]ponasterone A ([3H]PoA) in intact Sf-9 cells (Spodoptera frugiperda). The amount of [3H]PoA binding varied in a concentration-dependent manner. According to the IC50, concentration at which there is 50% ...

The association of ponasterone A (PNA) and 20-hydroxyecdysone with Kc cells is commensurate with their biological activity on this Kc cell line, the physiological activity ratio for PNA, 20-hydroxyecdysone and ecdysone is 1:50:2000, resp. Both association and release of [3H]-PNA are temperature-...

The goal of this study was to develop an inducible gene expression system to assess functions of specific proteins in differentiated cultured skeletal muscle. We utilized and modified the ecdysone inducible system because others have used this system to express exogenous genes in vitro and in tr...

Two stereoisomers of a castasterone/ponasterone A hybrid compound, the (20R,22R) and (20R,22S)-isomers of 2α,3α,20,22-tetrahydroxy-5α-cholestan-6-one, were synthesized stereoselectively and their binding activity to the ecdysteroid receptor was determined. From the concentration–response cur...

A series of ponasterone A (PNA) derivatives with various steroid moieties were synthesized to measure their binding activity to the ecdysone receptors of Drosophila Kc cells. The activity of compounds was evaluated by determining the concentration required to give the 50% inhibition (IC50 in M) ...

Organic phosphorus incorporated in calcite during laboratory precipitation experiments and in natural cave deposits was investigated by solid-state NMR spectroscopy. For calcite precipitated in the presence of organic phosphoesters of varying size and functionality, solid-state 31P{1H} CP/MAS NM...

In this study we demonstrate that chitosan solutions can be neutralised up to physiological pH (∼7.2) using β-glycerol phosphate without creating immediate gel-like precipitation and furthermore that subsequent heating of these solutions induces hydrogel formation. The addition of the particul...

Maintaining appropriate mechanical strength and tissue volume is important to provide for sufficient alveolar bone growth. Recently, synthetic bone graft materials (BGM) including hydroxyapatite (HA) and beta-tricalcium phosphate (β-TCP) have been widely studied for alveolar bone regeneration. ...

Over the last few years, increasing attention has been focused on the development of biomaterials that will be able to support axonal regeneration and will lead to successful recovery after spinal cord injuries. Especially hydrogels are being actively investigated due to their intrinsic properti...

SummaryNecroptosis is an inflammatory form of programmed cell death executed through plasma membrane rupture by the pseudokinase mixed lineage kinase domain-like (MLKL). We previously showed that MLKL activation requires metabolites of the inositol phosphate (IP) pathway. Here we reveal that I(1...

An injectable hydrogel for chondrocyte delivery was developed by blending chitosan and starch derived from various sources with β-glycerol phosphate (β-GP) in the expectation that it would retain a liquid state at room temperature and gel at raised temperatures. Rheological investigation indic...
