About 3,000 reports on oxidized cholesterols were published until 2011. Oxidized cholesterols are related to development of several diseases. Their physiological significance is as following; (1) interference of synthesis and/or action of steroid hormones, (2) intermediates in bile acids synthesis, (3) promotion or suppression of development of atherosclerosis, (4) ligands for LXR, (5) suppression of de novo cholesterol synthesis, (6) intermediates of cholesterol metabolism in the brain, and (7) disrupters of lipid metabolism by dietar y oxidized cholesterols. In order to grasp these phenomena, there has to be a better way to analyze oxidized cholesterols in vivo with accuracy.

: Based upon the wide q -range X-ray scattering study on stratum corneum, I will introduce that not only the structure of the intercellular lipid matrix but also the structure of soft keratin in the corneocytes plays an important role in function of the stratum corneum.

Polyunsaturated-fatty-acids have different physiological effects depending on the number and position of a double bond exists within the representative molecule, and the difference of acyl-chain length. According to the anti-obesity effects of polyunsaturated-fatty-acids, there are many researches with conjugated-fatty-acids (particularly conjugated-linoleic-acid) and n-3 polyunsaturated-fatty-acids (particularly eicosapentaenoic-acid, docosahexaenoic-acid, or fish oil which contains these fatty acids), which are conducted about the anti-obesity potentials and the mechanisms, possible effects on energy expenditure, lipid metabolism and so on, in cells, animals, and humans. In this review, we focus on conjugated-fatty-acids and n-3 polyunsaturated-fatty-acids in anti-obesity effects, and summarize of the potential of efficacy and possible mechanisms with recent reports.

Arachidonic acid, retinol and taurine are known to the cat : felis catus of the genuine flesh-eating animal as nutrient necessity. The required nature of the arachidonic acid depends on deficit of A6-desaturase. Therefore arachidonic acid cannot metabolize even if cat take in linoleic acid. Because the required nature of the retinol (vitamin A) deletes dioxygenase in the bowels, cat cannot resolve /3-carotene into retinol. Because cat do not have an enzyme composing taurine, it is necessary to take in the taurine which there is only to animal protein. It mean that EPA and DHA cannot metabolize even if the deficit of A6-desaturase takes in the linolenic acid of the n-3 fatty acid. It is necessary to take in the mammalian meat which contains them because it cannot metabolize even if the cat of the genuine flesh-eating animal takes in linoleic acid and the linolenic acid of the plant to get arachidonic acid, EPA and DHA. The fish contains arachidonic acid, retinol, and taurine other than EPA and DHA. The photoreceptor of the retina of the cat which a thing looks like in darkness, DHA, retinol and taurine are that is to say necessary for construction and the maintenance of the photoreceptor. The writer suggests a hypothesis that "the cat eats a fish when it cannot take in meat" from the above-mentioned reason.

The field of soft nanocapsules prepared via precision polymerization is briefly reviewed. The recent development of precision polymerization has provided us with versatile tools for synthesis of wide range of functional block copolymers with well-defined structure. The molecular dimensions influence the self-assembly and dictate their products such as nanoparticles and nanocapsules. In this review, general nanoparticles, which are classified 3 types such as homogeneous, core-shell, and hybridtype, were first described briefly. In the next place, the recent development of shell cross-linked micelles, namely SCK micelles, including in our results are focused on as a typical example of the coreshell typed nanoparticles. This shell cross-linked design leads to numerous potential applications in encapsulation, drug delivery, templating, nanoreacter, and many other.
