Diffusion and sorption behaviors of NaCl in surimis prepared from Pacific cod (Gadus morhua), red sea bream (Pagrus major) and big-eye tuna (Thunnus obesus) were studied. The variations of Fick's diffusion coefficients, D, of NaCl with respective maxima and of almost linear sorption isotherms were consistently interpreted with the dual mode diffusion and sorption theory. Good linear correlations were found between the concentrations of Langmuir mode sorption site, Sa, of NaCl (R2 = 0.993) and also thermodynamic diffusion coefficient of the Langmuir species, DT(L), of NaCl (R2 = 0.950), with charged amino acid contents in the surimis. The facts that Sa and DT(L) are related to the concentration of charged site suggest that the sites gather in a certain region, the water content of which becomes high with the site concentration. © 2014 Elsevier Ltd.

The effects of agar gel sample size on chewing and swallowing muscle properties were investigatedby electromyography and sensory evaluation. Crushedagar gel and cubic agar gels of 3.5mm (3.5mm cubic gel) and 15 mm (15mm cubic gel) were usedas samples. With the crushedagar gel, the change in activity of the masseter muscle was small, and the strength during mastication did not show a significant difference on sensory evaluation with higher chewing cycles. The activity time of the masseter muscle decreased slowly as the chewing frequency increased. The maximum voltage at 5 to 20 chewing cycles of the masseter muscle was the highest with the 3.5 mm cubic gel comparedto that with the other samples: however, the strength during mastication was comparable to that with the 15mm cubic gel on sensory evaluation. The time from the end of mastication to swallowing at 10 to 20 chewing cycles was the longest with the 15mm cubic gel comparedto the other samples. The section area of the masseter muscle at 5 chewing cycles was the largest with the 15mm cubic gel than with the other samples, but that and the time from the end of mastication to swallowing decreased remarkably. These results showedthat the activity of the masseter muscle was affectedby sample size. Copyright © 2014, Japanese Society for Food Science and Technology.

Novel pentacyclic ladder oligomethylsilsesquioxane was synthesized using cis,trans,cis-[MeSi(NCO)O] 4 as a building block. This compound was isolated in 13% yield by reprecipitation from the reaction mixture. X-ray crystallography revealed that pentacyclic rings assume a syn,anti,syn- configuration, resulting in the tube-like structure. © 2011 The Chemical Society of Japan.

Polyhedral oligomeric silsesquioxane (POSS) polymers were synthesized by the dehydrogenative condensation of (HSiO 3/2) 8 with water in the presence of diethylhydroxylamine followed by trimethylsilylation. Coating films were prepared by spin-coating of the coating solution prepared by the dehydrogenative condensation of POSS. The hardness of the coating films was evaluated using a pencil-hardness test and was found to increase up to 8H with increases in the curing temperature. Free-standing film and silica gel powder were prepared by aging the coating solution at room temperature. The silica gel powder was subjected to heat treatment under air atmosphere to show a specific surface area of 440 m 2 g -1 at 100 °C, which showed a maximum at 400 °C as 550 m 2 g -1.

All siloxane-type siloxane-polyhedral oligomeric silsesquioxane [(HSiO 3/2)8, T8 H] copolymers were synthesized by the dehydrogenative condensation of T8 H with diphenylsilanediol, tetraphenyldisiloxane-1,3-diol or silanol-terminated polydimethylsiloxanes in the presence of diethylhydroxylamine followed by trimethylsilylation. Coating films were prepared by spin-coating of the coating solutions prepared from the dehydrogenative condensation products. The hardness of the coating films was evaluated by a pencil hardness test and was found to increase up to 6H with increases in the curing temperature. Silica gels were prepared by concentrating the coating solution following by pyrolysis. These silica gels showed a specific surface area 449m2/g at 650 °C corresponding to the formation of a silica network in response to combustion of the phenyl groups.

Highly regulated ladder-structured polymethylsilsesquioxanes soluble in solvents with high molecular weight were synthesized from sila-functionalized tetramethylcyclotetrasiloxanes [MeSiXO]4 (X = H, OEt, NCO) by the dehydrogenative condensation of [MeSiHO]4 with water in the presence of N,N-diethylhydroxylamine or the hydrolytic polycondensation of [MeSiXO]4 (X = OEt, NCO). Formation of a siloxane-ladder structure was confirmed based on the appearance of two absorption bands and a signal due to Si-O-Si linkage in the infrared spectra and a silsesquioxane unit in 29Si nuclear magnetic resonance spectra, respectively. The narrow half-peak width of the 29Si nuclear magnetic resonance spectra suggested the formation of a highly regulated ladder structure for polymethylsilsesquioxanes. © 2010 Elsevier B.V.

Acid-catalyzed controlled hydrolytic polycondensation of tetraethoxysilane (TEOS) and tetramethoxysilane (TMOS) provided polyalkoxysiloxanes PEOS and PMOS, with high molecular weight of 1100-12 000 or 2700-31 000, respectively. They were stable to self-condensation, soluble in organic solvents, and especially characterized by high silica content of up to 62% (PEOS) and 72% (PMOS). Flexible and transparent free-standing films with tensile strength of 1.6-5.2 MPa (PEOS) or 3.6-11.8 MPa (PMOS) were prepared by heating polyalkoxysilanes at 80°C for one to several days. They are also regarded to be a potential precursor for coatings and binders. Copyright © 2012 John Wiley & Sons, Ltd.

All-cis-2,4,6,8-tetramethyl-2,4,6,8-tetrakis(triphenylsiloxy) cyclotetrasiloxane (4) and syn-1,3,9,11-tetramethyl-5,5,7,7,13,13,15,15- octaphenyltricyclo[9.5.1.1 3,9]octasiloxane (5) were synthesized by the reaction of cis,trans,cis-[MeSi(NCO)O] 4 (1) with Ph 3SiOH (2) and [Ph 2Si(OH)] 2O (3), respectively, in the presence of pyridine for the sake of investigating the synthesis of ladder polysilsesquioxanes with perfect siloxane frameworks. Their stereostructures were confirmed by nuclear magnetic resonance spectra and X-ray crystallography, which revealed that 4 and 5 did not retain the stereostructure of the precursor 1. This result was caused by the racemization of 1 with pyridine, and a subsequent nucleophilic substitution reaction of 1 with 2 or 3, including inversion and retention of the configuration at the silicon atoms. © 2010 Elsevier B.V.

3-Mercaptopropyl(trimethoxy)silane (MTMS)/1,2-bis(triethoxysilyl)ethane copolymer was synthesized by the hydrolytic polycondensation of the two alkoxysilanes in the presence of hydrochloric acid as a catalyst under nitrogen flow. Free-standing films were prepared by heating the copolymer at 80 °C for 4 days. The films were dipped in a 30% hydrogen peroxide solution at room temperature for 4 days. The sulfonated films were stable against hydrolysis and maintained their form at 150 °C. The sulfonyl group content of the film at 150 °C was 1.20 mmol g 1 when the composition of MTMS/1,2- bis(trimethoxysilyl)ethane was 1:2. © The Society of Polymer Science, Japan (SPSJ).

Energy metabolism and substrate oxidation during sleep correlate with sleep stage, suggesting that energy metabolism affects sleep architecture or vice versa. The aim of the present study was to examine whether changes in energy metabolism during sleep, induced by a high-carbohydrate or high-fat meal for dinner, affect sleep architecture. Ten healthy males participated in this study, sleeping 3 nonconsecutive nights in a whole-room calorimeter. The first night was scheduled as an adaptation to the experimental environment. The other 2 nights were experimental calorimetry in a balanced cross-over design with intrasubject comparisons. In each session, subjects comsumed a high carbohydrate (HCD: PFC=10 : 10 : 80) or high fat (HFD: PFC=10 : 78 : 12) meal at 2000 h and slept with a polysomnographic recording in a metabolic chamber for indirect calorimetry (0000 h to 0800 h). Slow wave sleep was decreased during the first sleep cycle and not changed during the second or third sleep cycle under HCD conditions compared with those of HFD. Energy expenditure was not affected by dietary condition but substrate oxidation reflected differences in dietary composition of the dinner during the first and second sleep cycle. The present study suggested the possibility that substrate availability during sleep affects substrate oxidation during sleep, and affects sleep architecture during the first sleep cycle.
