The National Coalition for Redress/Reparations was officially formed on July 12, 1980, and included members of the Los Angeles Community Coalition for Redress/Reparations (LACCRR), Japanese Community Progressive Alliance (JCPA), Tule Lake Committee, Nihonmachi Outreach Committee, the Asian/Pacific Student Union, and other members of the community. The material was collected by Jim Matsuoka, a founding member of the organization. Matsuoka also served on the board and was the treasurer. In addition to the NCRR material, the collection also contains event flyers and Day of Remembrance material.

Taxonomic revision of Pinus fujiii (Yasui) Miki (Pinaceae) and its implications for the phytogeography of the section Trifoliae in east Asia
No full textPinus trifolia Miki 1939 (Pinaceae) was originally proposed based on seed cones from the upper Miocene of Aichi and Gifu Prefectures, central Japan. However, before the publication of P. trifolia, a different name (Pinus fujiii (Yasui) Miki) was given to a female cone with the same morphology. On the other hand, P. fujiii auct. non (Yasui) Miki has been used for seed cones with different morphologies from Yasui's holotype, i.e., apophyses arranged in 5:8 parastichies and a perexcentromucronate slightly-pointed umbo. As a result of re-examination on the Miki and Yasui specimens, we concluded that P. trifolia was a synonym for P. fujiii and proposed here Pinus mikii sp. nov. for cones assigned to P. fujiii auct. non (Yasui) Miki. We also emended the diagnosis of P. fujiii based on these specimens. Pinus fujiii is characterized by a large female cone in which the apophyses with a centromucronate prickle-like umbo are arranged in 8:13 parastichies, and deciduous seed wings. These characters suggest that P. fujiii belongs to the section Trifoliae of the subgenus Pinus, which is now restricted to North and Central America and the Caribbean islands. Fossil data suggest that the P. fujiii lineage firstly appeared in Japan around the Eocene/Oligocene boundary. We speculate that the P. fujiii lineage might have moved southward to Japan from a refugium located elsewhere in high-latitude areas in response to the late Eocene cooling event, as occurred with other Trifoliae species in North America. © 2015 Yamada et al.

I. Facile preparation of ortho-fluorophenols from non-aromatic precursors and investigation of applications to fluorine-18 labeling II. Resin-supported silyl ester precursors for kit-like radiolabeling with fluorine-18
No full textMolecular imaging is a technique that can be used to visualize complex biochemical processes without perturbing living organisms, and it has been playing increasingly important roles for the early detection of disease states and monitoring the results of therapies. Among molecular imaging techniques, Positron Emission Tomography (PET) has significant advantages compared with other techniques, which includes its high sensitivity and high spatial resolution, and most importantly, its ability to provide functional information, whereas MRI or CT provide largely anatomical information. Among commonly used positron-emitting radionuclides, fluorine-18 has a number of preferred characteristics which are, 1) longest half-life, 109 minutes, 2) lowest maximum energy and 3) purest mode of decay. However, F-18 radiolabeling method is still underdeveloped, and thus, practical radiosyntheses are limited to nucleophilic substitution, especially at alkyl positions. Therefore, to extend the utility of F-18 for PET radiotracers, novel radiolabeling methods with F-18 that enable the preparation of a wide variety of radiotracers, rapidly, efficiently and conveniently are in highly demand in the field of radiochemistry.
Chapter 1 presents an introduction of PET imaging techniques, and outlines the basics of F-18 radiochemistry, which focuses on the synthetic difficulties associated with the nature of fluoride and especially F-18. It also highlights the current efforts placed on the development of novel fluorination methods toward F-18 radiosynthesis, especially C-F bond formation on electron-rich aromatic rings and use of fluorophilic elements for rapid preparation of radiotracers.
Chapter 2 discusses the development of a facile a fluorination method that produces ortho-fluorophenols from non-aromatic precursors. We have found that α-diazocyclohexenones undergo halofluorination with fluoride ion as fluoride source, and the following hydrohalide elimination and tautomerization afford ortho-fluorophenols rapidly. The translation to F-18 radiolabeling was achieved using organic soluble phase transfer catalysis under carrier-added conditions. Although labeling under non-carrier-added conditions is still a work in progress, our current progress points to a new approach to label electron-rich aromatic rings rapidly and at high specific activity (SA).
Chapter 3 discusses the development of a kit-like radiosynthetic method using a resin-supported silicon based precursor. We have found that silyl esters have significant advantages over previously reported methods; they undergo F-18 incorporation under very mild conditions, with F-18 water straight from the cyclotron used without any drying. We further developed the resin-supported method which enables simple purification of the radiotracer. The utility of this approach is showcased in three main area of research: prosthetic groups, small molecules and peptides.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2017-08-01The student, Norio Yasui, accepted the attached license on 2015-06-30 at 13:33.The student, Norio Yasui, submitted this Dissertation for approval on 2015-06-30 at 13:49.This Dissertation was approved for publication on 2015-07-01 at 11:47.DSpace SAF Submission Ingestion Package generated from Vireo submission #8302 on 2015-09-29 at 15:05:18Made available in DSpace on 2015-09-29T21:02:53Z (GMT).
