Broadening participation in STEM

Yonezawa S.
GSID: -JMKBxxJDioJ
S Yonezawa, N Renner, M Sweet, B Simon, D Baxter - ACM Inroads, 2015 - dl.acm.org

In 2011, the National Science Foundation (NSF) funded teams at University of California San Diego (UCSD) and San Diego State University (SDSU) to conduct research on adapting a collegelevel course, CS Principles (CSP), for high schools in San Diego...

[Modeled events and observers' traits underlying observational learning of altruistic behavior].

Shinrigaku kenkyu : The Japanese journal of psychology

Yoshimi Y, Yonezawa S, Matsui H.
PMID: 3450911
Shinrigaku Kenkyu. 1987 Oct;58(4):218-25. doi: 10.4992/jjpsy.58.218.

The present experiments investigated the changes of altruistic responses through observational learning (OL) in elementary school children (ages 10 and 11) with relation to the characteristics of the modeled events and the observers' traits. The former included certain categories...

A ferromagnetically coupled Fe42 cyanide-bridged nanocage.

Nature communications

Kang S, Zheng H, Liu T, Hamachi K, Kanegawa S, Sugimoto K, Shiota Y, Hayami S, Mito M, Nakamura T, Nakano M, Baker ML, Nojiri H, Yoshizawa K, Duan C, Sato O.
PMID: 25562786
Nat Commun. 2015 Jan 06;6:5955. doi: 10.1038/ncomms6955.

Self-assembly of artificial nanoscale units into superstructures is a prevalent topic in science. In biomimicry, scientists attempt to develop artificial self-assembled nanoarchitectures. However, despite extensive efforts, the preparation of nanoarchitectures with superior physical properties remains a challenge. For example,...

Recovery of palladium, cesium, and selenium from heavy metal alkali borosilicate glass by combination of heat treatment and leaching processes.

Journal of hazardous materials

Xu Z, Okada T, Nishimura F, Yonezawa S.
PMID: 28273566
J Hazard Mater. 2017 Jun 05;331:171-181. doi: 10.1016/j.jhazmat.2017.02.032. Epub 2017 Feb 22.

Reductive heat-treatment and leaching process were applied to a simulated lead or bismuth soda-potash-borosilicate glass with palladium, cesium, and selenium to separate these elements. In the reductive heat treatment, palladium is extracted in liquid heavy metal phase generated by...

Loss of γ-tubulin, GCP-WD/NEDD1 and CDK5RAP2 from the Centrosome of Neurons in Developing Mouse Cerebral and Cerebellar Cortex.

Acta histochemica et cytochemica

Yonezawa S, Shigematsu M, Hirata K, Hayashi K.
PMID: 26633906
Acta Histochem Cytochem. 2015 Oct 29;48(5):145-52. doi: 10.1267/ahc.15023. Epub 2015 Oct 21.

It has been recently reported that the centrosome of neurons does not have microtubule nucleating activity. Microtubule nucleation requires γ-tubulin as well as its recruiting proteins, GCP-WD/NEDD1 and CDK5RAP2 that anchor γ-tubulin to the centrosome. Change in the localization...

Total Synthesis of Terprenin, a Novel Immunosuppressive p-Terphenyl Derivative.

The Journal of organic chemistry

Yonezawa S, Komurasaki T, Kawada K, Tsuri T, Fuji M, Kugimiya A, Haga N, Mitsumori S, Inagaki M, Nakatani T, Tamura Y, Takechi S, Taishi T, Ohtani M.
PMID: 11672184
J Org Chem. 1998 Aug 21;63(17):5831-5837. doi: 10.1021/jo980349t.

We achieved a total synthesis of terprenin, a novel potent immunoglobulin E antibody suppressant which was obtained from the fermentation broth of Aspergillus candidus RF-5672 and has a highly oxygenated p-terphenyl skeleton with a prenyloxy side chain. The key...

Thermodynamic simulation of magnetic-field-modulation methods for pulsed laser irradiation in magneto-optical disks.

Applied optics

Yonezawa S, Takahashi M.
PMID: 20885583
Appl Opt. 1994 Apr 20;33(12):2333-7. doi: 10.1364/AO.33.002333.

Direct overwrite magnetic-field modulation recording with dc and pulsed laser irradiation in a magneto-optical disk was simulated thermodynamically. Because the laser light heats the magnetic film, which allows the magnetization to be reversed, the waveform of the laser light...

Optogenetics 3.0.

Cell

Liu X, Tonegawa S.
PMID: 20371341
Cell. 2010 Apr 02;141(1):22-4. doi: 10.1016/j.cell.2010.03.019.

Optogenetic methods use light to modulate the activities of target cells in vivo. By improving inter- and intracellular trafficking of light-sensitive switch proteins called opsins, Gradinaru et al. (2010) have developed a new generation of optogenetic tools capable of...

Dual function of Sec16B: Endoplasmic reticulum-derived protein secretion and peroxisome biogenesis in mammalian cells.

Cellular logistics

Tani K, Tagaya M, Yonekawa S, Baba T.
PMID: 22279616
Cell Logist. 2011 Jul;1(4):164-167. doi: 10.4161/cl.1.4.18341. Epub 2011 Jul 01.

The origin of peroxisomes has long been disputed. However, recent evidence suggests that peroxisomes can be formed de novo from the endoplasmic reticulum (ER) in yeast and higher eukaryotes. Sec16A and Sec16B, mammalian orthologs of yeast Sec16, are scaffold...

Radiofrequency capacitive hyperthermia for superficial malignant-tumors.

International journal of oncology

Fujimura T, Yonemura Y, Fushida S, Urade M, Kamata T, Takegawa S, Sugiyama K, Nishimura G, Miwa K, Miyazaki I, Nakajima K, Hisazumi H, Saito Y, Takashima T.

Int J Oncol. 1993 Jun;2(6):1017-22. doi: 10.3892/ijo.2.6.1017.

Eighteen patients with inoperable head, neck and upper chest wall cancers underwent radiofrequency hyperthermia in combination with chemotherapy and radiotherapy (HCR therapy). Of the eighteen patients, three showed complete response (CR); eight, partial response (PR); four, no change (NC);...

Photoswitchable dynamic magnetic relaxation in a well-isolated {Fe2Co} double-zigzag chain.

Angewandte Chemie (International ed. in English)

Front Behav Neurosci. 2014 Jan 17;7:226. doi: 10.3389/fnbeh.2013.00226. eCollection 2013.

With the accumulation of our knowledge about how memories are formed, consolidated, retrieved, and updated, neuroscience is now reaching a point where discrete memories can be identified and manipulated at rapid timescales. Here, we start with historical studies that...
