Changes in viscosity of cocoa butter and chocolate during crystallization processes were measured by a rotational viscometer which was newly equipped in the present study. This viscometer facilitates a computerized tempering with agitation of the sample, yielding a torque of sample. The tempering process was a simple cooling of melt (60°C) to several crystallization temperatures. It was confirmed that the torque was linearly proportional to viscosity values obtained by Brookfield type viscometer. The viscosity changed through three different stages : First, the constant viscosity was attained after the crystallization temperature was reached. Second, the viscosity gradually increased due to early nucleation and crystal growth of solid fats. Third, a sharp increase of viscosity was caused by accelerated crystallization. The amount of crystallized fats in chocolate during the industrial-used tempering machine (60-27-30°C) was estimated about 0.17%, based on the viscosity changes examined by the present method.

糖脂質GM3は細胞増殖の密度に応じて増加する。細胞膜のGM3は細胞増殖機能の重要なモジュレータである。一部分のGM3の代謝回転は末端に存在するシアル酸残基によって調節されている。GM3代謝酵素すなわちシアリターゼとシアル酸転移酵素の活性は細胞分裂している細胞において変化する。両酵素は, 上皮成長因子受容体のリン酸化のGM3が介在する阻害反応とともに, 細胞増殖制御において機能している。2-デオキシ-2, 3-デヒドロ-N-アセチルノイラミン酸 (NeuAc2en) はGM3シアリダーゼの有効な阻害剤であり, 細胞増殖阻害効果を示す。新しいインフルエンザウイルス感染の治療法の開発にNeuAc2enよりコンピューターを利用して分子設計された類縁体 (強力な阻害剤) が用いられた。CMP-シアル酸は生理的条件でNeuAc2enを非酵素的に生成する。生成したNeuAc2enは細胞のシアリダーゼ活性を調節している可能性が指摘できる。GM3シアリダーゼとシアル酸転移酵素の細胞内での機能を明らかにするためには, 細胞内の酵素存在部位にターゲッテングされるNeuAu2enおよびCMP-シアル酸の新タイプの類縁体が分子設計される必要がある。

A new breakthrough for zinc (II) enzyme models was achieved with the advent of macrocyclic polyamine zinc (II) complexes. These complexes serve as the best structural as well as functional model for the active centers of zinc (II) enzymes (e.g., carbonic anhydrase, alkaline phosphatase, and alcohol dehydrogenase) and have clearly answered mysteries surrounding the intrinsic properties of zinc (II) in the zinc (II) enzymes. The knowledge newly gained about the properties of zinc (II) has been developed into new supramolecular chemistry, where the zinc (II) enzyme model complexes can recognize thymine and its related derivatives among all the nucleobases in aqueous solution. Here new biochemical functions of the zinc complexes (i.e., inhibition of hybridization of polyribonucleic acids, inhibition of in vitro protein synthesis, inversion of DNA helicity, etc.) are also presented.

Alaska pollack protein (APP) was previously shown to reduce serum triacylglycerol and the atherogenic index and significantly increase gastrocnemius muscle mass in rats. To determine which myofibers are involved in this observed hypertrophy, we stained the gastrocnemius muscle with fast and slow fiber-specific antibodies and measured the muscle fiber diameter. We observed muscle hypertrophy in both the fast and slow fibers of APP-fed rats. Although muscle hypertrophy leads to drastic lipid changes, the amount of lipids did not differ significantly between casein-fed and APP-fed rats. To determine the lipid changes at the molecular species level and their localization, we performed matrix-assisted laser desorption/ionization mass spectrometry imaging to visualize lipids in the gastrocnemius muscles. We determined that lipid molecules were significantly changed due to APP feeding. Thus, APP feeding changes muscle lipid metabolism, and these metabolic changes might be related to hypertrophy.

A rapid method is described for the separation and determination of nonionic substances in detergents by use of a centrifugal chromatograph. The sample was placed on the center of a circular alumina disk and eluted with 300 ml of a mixed solvent, ethyl acetate/methanol (1 : 1, vol/vol), rotating the disk at 400 rpm. By this method nonionic substances such as alkyl poly (oxyethylene) ether and N, N-bis (2-hydroxyethyl) alkanamide in commercial detergents and shampoos were separated quantitatively within 10 min without the interference from coexisting anionic surfactants. The analytical results agreed with those obtained by the column chromatography on alumina.

We have developed an artificial skin that mimics the morphological and mechanical properties of human skin. The artificial skin comprises a polyurethane block possessing a microscopically rough surface. We evaluated the tactile sensations when skin-care cream was applied to the artificial skin. Many subjects perceived smooth, moist, and soft feels during the application process. Cluster analysis showed that these characteristic tactile feels are similar to those when skin-care cream is applied to real human skin. Contact angle analysis showed that an oil droplet spread smoothly on the artificial skin surface, which occurred because there were many grooves several hundred micrometers in width on the skin surface. In addition, when the skin-care cream was applied, the change in frictional force during the dynamic friction process increased. These wetting and frictional properties are important factors controlling the similarity of artificial skin to real human skin.

During ancient times in China, bee pollen was used for skin whitening and beauty. Around 70% of substances in bee pollen are biologically active, such as proteins, carbohydrates, lipids and fatty acids, phenolic compounds, vitamins and bioelements.This review describes the cosmeceutical properties of bee pollen and the mechanism of its active components action, its beneficial influence on human skin. As a natural bee product, bee pollen may effectively enhance protective mechanisms against skin aging, skin dryness, ultraviolet B radiation, oxidative damage, inflammatory and melanogenesis, which are involved in a wide range of negative effects on human skin, thus they have attracted attention for health and cosmetic applications.

Triacylglycerols have specific properties which are useful for processing and/or modification of food systems according to their polymorphism, hydrophobic/hydrophilic balance, digestibility, and so on. These phenomena are mainly governed by the structure. Interfacial properties of 3-butyryl-1, 2-dipalmitoylglycerol at O/W emulsion, specific anti-bloom effect of 2-oleoy1-1, 3 dibehenylglycerol and restriction of absorption for 2-stearoyl-1, 3-dihexanoylglycerol are good examples. In the present study, we intend to summarize the relation between the structure and their specific properties.

We evaluated the friction properties of five cosmetic sponges on artificial skin using sinusoidal motion-friction evaluation system. No significant difference was observed in the pleasant score of the five sponges when these sponges were rubbed on the skin surface. The sponges were classified into three groups based on their tactile feel. Their characteristic tactile textures were moist-soft-slippery, moist-dry-rough, and moist feels. The slippery feel was found to depend on the thickness of the sponge’s cell wall, its surface tension, and the change in friction coefficient in the dynamic friction process. These findings are useful in the design of cosmetic sponges.

Foaming profile differs from one application to others due to the many variables relating to the foaming phenomena such as chemicals in the system, physical and mechnical conditions. Therefore, discussing defoaming or antifoaming exhibits much more complexity than the simple act of foaming. Due to the sheer complexity concerned, the actual technology seems to precede scientific understanding.In a wide range of industries, silicone antifoams are the most effective antifoams in both aqueous surfactant systems and nonaqueous systems. The efficiency can be explained by the surface chemical characteristics of the silicone polymer, which are derived from its unique structure such as backbone flexibility and low intermolecular forces, especially for polydimethylsiloxane.In this paper, defoaming by polysiloxane polymers is explained by the surface chemical nature of the polymer. As well, in aqueous systems, enhanced defoaming by compounding hydrophobic silica is explained by dewetting mechanisms based on previous theories.

Lung surfactant, besides alveolar stability, also provides defence against pathogens by surfactant proteins (SP), SP-A and SP-D. The hydrophobic proteins SP-B and SP-C enhance surface activity. An unusual and paradoxical effect of bovine LS and synthetic model LS with SP-B/-C was bactericidal to Staphylococcus aureus and Escherichia coli. Bacterial proliferation were investigated with bovine lung surfactant extract (BLES), dipalmitoylphosphatdylcholine, palmitooleylglycerol, in combination with SP-B/-C using standard microbiological colony forming unit (CFU) counts and structural imaging. BLES and other surfactant-SP-B/-C mixtures inhibit bacterial growth in the concentration range of 0 -7.5 mg/mL, at > 10 mg/mL paradoxical growth of both the bacterial species suggest antibiotic resistance. The lipid only LS have no effect on bacterial proliferation. Smaller peptide mimics of SP-B or SP-B1-25, were less efficient than SP-Cff. Ultra structural studies of the bacterial CFU using electron and atomic force microscopy suggest some membrane damage of S. aereus at inhibitory concentration of BLES, and some structural alteration of E. coli at dividing zones, suggesting utilization and incorporation of surfactant lipid species by both bacteria. The results depicted from in vitro studies are also in agreement with protein-protein interactions obtained from PatchDock, FireDock and ClasPro algorithm. The MD-simulation decipher a small range fluctuation of gyration radius of the LS proteins and their peptide mimics. The studies have alarming implications in using of high dosages (100 mg/mL/kg body weight) exogenous surfactant for treatment of respiratory distress syndrome, genetic knock-out abnormalities associated with these proteins, and the novel roles played by SP-B/C as bactericidal agents.

Volatile compounds and quality changes of bitter apricot (Armeniaca sibirica L.) kernel oil (AKO) with different roasting conditions were determined. Bitter apricot kernels were roasted at 120, 130, 140 and 150°C for 15 min. Unroasted bitter apricot kernel oil was used as the control. Quality indicators included color, acid value and peroxide value, fatty acids, total phenols and oxidative stability. Peroxide values of the tested oils were 0.46-0.82 meq/kg, acid values were 0.60-1.40 mg KOH/g, and total phenol contents were 54.1-71.5 μg GAE/g. Oleic acid was the major fatty acid, followed by linoleic, palmitic, stearic and palmitoleic acids. Roasting increased the oxidative stability of bitter AKO. Volatile compounds were tentatively identified and semi-quantified. Among the 53 volatiles identified, benzaldehyde and benzyl alcohol were the major components. These two aroma compounds increased significantly during roasting and contributed sweet and almond flavors. Pyrazines were also prevalent and significantly increased with roasting. Sensory evaluation showed that roasted, nutty, sweet and oily aromas increased as roasting temperature increased.Practical applications: Bitter apricot kernels cannot be consumed directly, thus it is potentially beneficial to find uses for them, especially in China where bitter apricot processing is a significant industry. Roasted bitter AKO with a pleasant aroma could be prepared and might find use as an edible oil. The roasting process gave the bitter AKO a pleasant flavor. This study provided preliminary information on production parameters and potential quality control parameters.
