Dissection of c-myc domains involved in S phase induction of NIH 3T3 fibroblasts
No full textThe product of the c-myc proto-oncogene is an important regulator of cell proliferation and apoptosis in murine fibroblasts. Addition of the tumor promoter, phorbol myristate acetate (PMA), prevents apoptotic cell death induced by low serum concentrations in NIH3T3 cells that constitutively express and are transformed by v-myc. The protective effect of PMA allowed us to analyse the ability of normal c-Myc and Myc deletion mutants to induce serum starved, untransformed NIH3T3 cells to enter S phase. By microinjecting these quiescent cells with wild type and mutant human c-myc plasmids, we showed that full length c-myc is able to induce S phase entry in presence of PMA, but that c-Myc mutants that delete amino acids delta 7/91, delta 41/53, delta 56/103, delta 106/143, delta 265/317 and delta 414/433 are totally inactive. c-Myc did not shorten the period before entry into S phase, since Myc overexpressing cells entered S phase with the same kinetics as control cells when both were stimulated with 20% fetal calf serum (FCS). However, c-Myc overexpression did increase the percentage of cells entering S phase when these cells were stimulated with 2% fetal calf serum. Interestingly, this ability to enhance stimulation by a suboptimal concentration of FCS was retained to a significant degree by Myc mutants that delete amino acids delta 41/53, delta 56/103 or delta 265/317. Finally, Myc mutants that delete delta 106/143 or delta 414/433 exerted a dominant negative effect on S phase entry both in quiescent cells stimulated with 2% FCS and in unsynchronized, cycling cells

Synthesis of Co(3)O(4) nanowire arrays supported on Ni foam for removal of volatile organic compounds
No full textCrystalline Co3O4 nanowire arrays freely supported on Ni foam are successfully synthesized using a template-free method. The effects of reaction time, concentration of reactants, and temperature on the morphology of the nanowires are studied. The results indicate that uniform Co3O4 nanowires could be synthesized at 90 degrees C, and a transformation of the samples' morphology from nanoparticles to nanowires to microrods is observed by controlling the concentration of the reactants. The well-ordered nanowires synthesized under the selected reaction conditions are composed of spinel Co3O4 with diameters of 500-580 nm and lengths of 6-8 microm. These nanowires show good catalytic activity for the ozone catalytic oxidation of toluene.Hui, K. N.; Yin, Cui-Lei; Hui, K. S.; Lee, J. Y.; Li, M.; Lee, S. K.; Tsui, K.

Mark C. Lee
No full textMark Lee is currently the Director of Aerospace Facilities for Affiliated Engineers. Lee is married to the former Paula Marie Simon of Chicago, Illinois. They have three boys, Erik, Matthew, and Jonathon.
Lee received a bachelor of science degree in civil engineering from the U.S. Air Force Academy in 1974, and a master of science degree in mechanical engineering from Massachusetts Institute of Technology in 1980.
SPECIAL HONORS: Distinguished Flying Cross, Defense Superior Service Medal, Legion of Merit, Defense Meritorious Service Medal, Air Force Meritorious Service Medal, 2 Air Force Commendation Medals, 4 NASA Space Flight Medals, NASA Distinguished Service Medal, NASA Outstanding Leadership Medal, NASA Public Service Group Achievement Award, and 2 NASA Exceptional Service Medals.
EXPERIENCE: Following pilot training at Laughlin Air Force Base, Texas, and F-4 upgrade at Luke Air Force Base, Arizona, Lee spent 2-1/2 years at Okinawa Air Base, Japan, flying F-4’s in the 25th Tactical Fighter Squadron. Following this assignment, he began his studies at MIT in 1979 specializing in graphite/epoxy advanced composite materials. After graduation in 1980, he was assigned to Hanscom Air Force Base, Massachusetts, in the Airborne Warning and Control System (AWACS) Program Office, as the operational support manager. His responsibilities included resolving mechanical and material deficiencies which affected the mission readiness of the AWACS aircraft. In 1982 he returned to flying, upgrading in the F-16 and serving as executive officer for the 388th Tactical Fighter Wing Deputy Commander for Operations, and as flight commander in the 4th Tactical Fighter Squadron at Hill Air Force Base, Utah, until his selection as an astronaut candidate.
He has logged 4,500 hours flying time, predominantly in the T-38, F-4 and F-16 aircraft.
NASA EXPERIENCE: Lee was selected as an astronaut candidate by NASA in May 1984. In June 1985, he completed a one-year training and evaluation program, qualifying him for assignment as a mission specialist on future Space Shuttle flight crews. His technical responsibilities within the Astronaut Office have included extravehicular activity (EVA), the inertial upper stage (IUS), Spacelab and Space Station systems. Lee has also served as a spacecraft communicator (CAPCOM) in the Mission Control Center, as Lead \u27\u27Cape Crusader\u27\u27 at the Kennedy Space Center, Chief of Astronaut Appearances, Chief of the Astronaut Office Mission Development Branch, Chief of the EVA Robotics Branch, and Chief of the EVA Branch. He also worked Space Station assembly issues for the Astronaut Office.
A veteran of four space flights, Lee has traveled over 13 million miles going around the world 517 times and spending 33 days in orbit. He flew as a mission specialist on STS-30 (May 4-8, 1989) and STS-64 (September 9-20, 1994), and was the Payload Commander on STS-47 (September 12-20, 1992), and STS-82 (February 11-21, 1997). During STS-64, he logged EVA hours totaling 6 hours and 51 minutes. During STS-82 he logged 19 hours and 10 minutes in 3 EVAs. Lee retired from NASA and the Air Force effective July 1, 2001.https://commons.erau.edu/space-congress-bios-2019/1039/thumbnail.jp
