    July, 2014 Next Meeting July 19th, 11:00AM at LIGO The LIGO facility in Livingston Parish, LA What's In This Issue? President's Message Secretary's Summary of June Meeting Astroshort- Not-So-Rare Earths Message from the HRPO Globe At Night EBR Parish Library Children's Reading Program Recent BRAS Forum Entries Observing Notes from John Nagle President's Message WE WILL NOT MEET ON THE SECOND MONDAY NIGHT, AS WE USUALLY DO. Our next meeting will be Saturday, July 19, 2014, 11 AM – 4 PM at LIGO, Livingston. It will be a picnic/star-b-cue and enjoy each other’s company. We will meet under the pavilion by the pond at 11 AM to begin the picnic. BRAS will provide the main course. You can bring a small dish if you wish. At 1 PM, we can join the public for LIGO’s regular Saturday Science day activities. That includes the museum, hands on experiments, a video about LIGO “Einstein’s Messengers”, and a tour of the facility. One new thing we would like to do is set a table aside for anyone who has astronomical equipment they want to sell – telescopes, mounts, accessories, binoculars, cameras, books, etc. The idea is to have an impromptu garage sale (or swap meet). Bring what you have and let’s see if we can move it. LIGO is only open during the day, so the only stargazing we will be able to do will be solar. However, we will demonstrate the 35mm Lundt solar scope BRAS is raffling and sell tickets for the raffle.

  • The Planetary Nebula Club Objects by Month (As Posted by Ted Forte On
    The Planetary Nebula Club objects by month (As posted by Ted Forte on “backbayastro”) August Planetaries As most of you know, I am the coordinator of the Astronomical League’s Planetary Nebula Club. Several members of the BBAA helped me create the Planetary Nebula Club by serving on the object selection committee, serving on the rules committee, providing images, or by authoring parts of the observing manual. The Planetary Nebula Club creation was truly a BBAA effort. I think it’s a shame, therefore, that more BBAA’ers haven’t completed the program and earned the pin. So if you are looking for an observing program to complete, why not our very own? There was never a better time to start. More than half the list is visible right now and no less than 31 of our 110 PNe are optimally placed in August. Hence the title of this epistle. It is my intention to spark an interest in the program and suggest the objects that might be bagged in the coming weeks. Many of you have no doubt observed these objects already, so please chime in and share your impressions of them. As is true of the entire list, our August selection contains both well-known showpieces and some seldom mentioned objects that you might not consider tracking down if not for this program. There are no less than 17 of the 31 August objects that I would describe as “stellar”. I must confess that I am not the biggest fan of these tiny objects and had I been the sole arbiter of the list it would have contained far fewer of these.

  • The Role of Phosphoinositide 3-Kinase/Akt Signaling
    THE ROLE OF PHOSPHOINOSITIDE 3-KINASE/AKT SIGNALING PATHWAY IN TUMOR-ASSOCIATED ANGIOGENESIS, WOUND HEALING, AND CARCINOGENESIS Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Nesrine Ismail Affara, M.S. The Ohio State University 2006 Dissertation Committee: Approved by Dr. Fredika M. Robertson, Adviser Dr. Robert M. Snapka Dr. Anthony P. Young Adviser Dr. Susheela Tridandapani Graduate Program in Molecular, Cellular, and Developmental Biology Copyright by Nesrine Ismail Affara 2006 ABSTRACT The goal of the present studies was to localize two proteins known to be involved in regulation of cell proliferation and survival in specific cell populations in normal mouse skin, during multi-stage skin carcinogenesis, following skin injury, and during tumor angiogenesis. The proteins evaluated included activated Akt, as defined by phosphorylation of Akt at Serine-473 (pAkt) and mTOR, defined by phosphorylation of mTOR at Serine-2448 (pmTOR). Our laboratory previously identified a novel murine VEGF splice variant, VEGF205*, which was differentially expressed in mouse skin carcinomas, but not in normal skin. VEGF205* encodes for a truncated 145 amino acid polypeptide with a unique 7 amino acid carboxyl-terminal tail, YVGAAAV, that is significantly different from the carboxyl-terminal tail of other mouse or human VEGF proteins previously identified. In the present studies, we demonstrate that VEGF205* stimulated a significant increase in Akt phosphorylation at Serine-473 residue in human vascular endothelial cells compared to VEGF120. Akt phosphorylation following exposure of endothelial cells to VEGF205* was completely blocked by the PI3-K inhibitor, LY294002.
