Theory of the Flower Micelle Formation of Amphiphilic Random and Periodic Copolymers in Solution.

Authors:
Takahiro Sato

Polymers (Basel) 2018 Jan 14;10(1). Epub 2018 Jan 14.

Department of Macromolecular Science, Osaka University, 1-1 Machikaneyama-cho, Toyonaka, Osaka 560-0043, Japan.

The mixing Gibbs energy Δ for the flower-micelle phase of amphiphilic random and periodic (including alternating) copolymers was formulated on the basis of the lattice model. The formulated Δ predicts (1) the inverse proportionality of the aggregation number to the degree of polymerization of the copolymer, (2) the increase of the critical micelle concentration with decreasing the hydrophobe content, and (3) the crossover from the micellization to the liquid⁻liquid phase separation as the hydrophobe content increases. The transition from the uni-core flower micelle to the multi-core flower necklace as the degree of polymerization increases was also implicitly indicated by the theory. Read More

Structural Analysis of Hydrophobe-Uptake Micelle of an Amphiphilic Alternating Copolymer in Aqueous Solution.

Langmuir 2016 08 29;32(31):7875-81. Epub 2016 Jul 29.

Department of Macromolecular Science, Osaka University , 1-1 Machikaneyama-cho, Toyonaka, Osaka 560-0043, Japan.

We investigated the structure of the hydrophobe-uptake micelle of an alternating amphiphilic copolymer in aqueous solutions, by combining light scattering and small-angle X-ray scattering (SAXS). When the copolymer micelle includes the hydrophobe (1-dodecanol), the unicore flower micelle transforms into the multicore flower necklace, and the flower necklace is slightly stiffer than the hydrophobe-free flower necklace of the same copolymer. Moreover, the hydrophobe is included not in the hydrophobic core region but in the intermingled region of the hydrophobic group and the loop chain of the unit flower micelle. Read More

A report from the 164th American Psychiatric Association (May 14-18, 2011 - Honolulu, Hawai'i, U.S.A.).

Medical Department, Thomson Reuters, Barcelona, Spain.

Although tradition mandates that men should be dressed up in colorless attires, why do men visiting Hawai'i run to the first Aloha shop right after landing to get a multicolored flowery shirt, with a lei flower or kukui tree nut necklace to go with it? The answer to this question could be very complex, but psychiatrists attending this year's American Psychiatric Association meeting in the Honolulu Convention Center acted in a not dissimilar way by running to the new research poster and educational oral sessions of the meeting to learn new colors to paint the life of their patients with. And many colors, or at least an ample variety of treatment modalities, were discussed throughout the 5-day convention, including, notably, a number of innovative drugs with the capability of improving the functioning and quality of life of individuals suffering from psychosis, depression and a broad range of psychiatric diseases. The following report summarizes the main findings from clinical and experimental studies related to new psychiatric pharmacotherapies as reported and discussed during the meeting. Read More
