Funktionelle Analyse von intrazellulären Signalwegen bei der Migration der embryonalen peripheren Gliazellen von Drosophila melanogaster

Im Rahmen dieser Arbeit wurden Signalwege untersucht, die an der Migration der embryona-len peripheren Gliazellen (ePG) beteiligt sind. Der Fokus lag dabei auf Myoblast city (Mbc). Zunächst wurden dazu unterschiedliche mbc Mutanten analysiert, bei denen es zu starken glialen Migrationsdefekten kommt. Um die auftretenden Phänotypen quantitativ zu analysieren, wurde eine Methode entwickelt um die Position der Pionierglia ePG9 zu bestimmen. Dies ermöglicht es, auch sehr subtile gliale Migrationsphänotypen zu detektieren. Durch knock-down Experimente konnte gezeigt werden, dass Mbc eine zellautonome Rolle bei der glialen Migration spielt. Besonders interessant ist die Tatsache, dass während der Migration der ePG eine alternativ gespleißte Isoform benötigt wird, die bisher kaum untersucht wurde. Durch Strukturvorhersagen konnte gezeigt werden, dass sich der Bereich in dem sich die beiden Isoformen unterscheiden, in einer Region liegt, die sich zu HEAT-repeats faltet. Mbc-PB scheint somit über einen Bereich zu verfügen, der im Vergleich zu Mbc-PA, zusätzliche Interaktionen erlaubt. Zudem scheint es mehrere Phosphorylierungsstellen zu geben, die für die Inaktivierung von Mbc-PB notwendig sind. Die Kinase Wallenda konnte als Kandidat identifiziert werden, der für die Phosphorylierung von Mbc-PB verantwortlich ist. Weitere Experimente zeigten eine einen zellautonomen Einfluss von Mbc-PB auf ePG7, die indirekt die Migration der Pionierglia ePG9 beeinflusst.

An integrated system for building and running reproducible research

Our generation of computational scientists is living in an exciting time: not only do we get to pioneer important algorithms and computations, we also get to set standards on how computational research should be conducted and published. From Euclid’s reasoning and Galileo’s experiments, it took hundreds of years for the theoretical and experimental branches of science to develop standards for publication and peer review. Computational science, rightly regarded as the third branch, can walk the same road much faster. The success and credibility of science are anchored in the willingness of scientists to expose their ideas and results to independent testing and replication by other scientists. This requires the complete and open exchange of data, procedures and materials. The idea of a “replication by other scientists” in reference to computations is more commonly known as “reproducible research”. In this context the journal “EAI Endorsed Transactions on Performance & Modeling, Simulation, Experimentation and Complex Systems” had the exciting and original idea to make the scientist able to submit simultaneously the article and the computation materials (software, data, etc..) which has been used to produce the contents of the article. The goal of this procedure is to allow the scientific community to verify the content of the paper, reproducing it in the platform independently from the OS chosen, confirm or invalidate it and especially allow its reuse to reproduce new results. This procedure is therefore not helpful if there is no minimum methodological support. In fact, the raw data sets and the software are difficult to exploit without the logic that guided their use or their production. This led us to think that in addition to the data sets and the software, an additional element must be provided: the workflow that relies all of them.

[Guidance of interventions in subintimal recanalization and fenestration of dissection membranes using a novel dual-lumen intravascular ultrasound catheter]

PURPOSE: To evaluate the feasibility and effectiveness of IVUS-guided puncture for gaining controlled target lumen reentry in subintimal recanalization of chronic iliac/femoral artery occlusions and in fenestration of aortic dissections. MATERIALS AND METHODS: Between 5/2004 and 12/2005 12 consecutive patients (7 male, 5 female; mean age 64.6 +/- 12.0 years) with chronic critical limb ischemia and ischemic complications of aortic dissection were treated using the Pioneer catheter. This 6.2-F dual-lumen catheter combines a 20-MHz IVUS transducer with a pre-shaped extendable, hollow 24-gauge nitinol needle. This coaxial needle allows real-time IVUS-guided puncture of the target lumen and after successful reentry a 0.014" guidewire may be advanced through the needle into the target lumen. 7 patients were treated for aortic dissection and 5 patients (with failed previous attempts at subintimal recanalization) for chronic arterial occlusion. Patients with aortic dissection (5 type A dissections, 2 type B dissections) had developed renal ischemia (n = 2), renal and mesenteric ischemia (n = 2), or low extremity ischemia (n = 3). Patients with chronic arterial occlusions (2 common iliac artery occlusions, 3 superficial femoral artery occlusions) experienced ischemic rest pain (n = 4), and a non-healing foot ulcer (n = 1). RESULTS: The technical success rate using the Pioneer catheter was 100%. The recanalization/fenestration time was 37 +/- 12 min. Procedure-related complications did not occur. In 10 cases a significant improvement of clinical symptoms was evident. One patient with aortic dissection and ischemic paraplegia required subsequent surgical intervention. One patient had persistent ischemic rest pain despite successful recanalization of a superficial femoral artery occlusion. CONCLUSION: The Pioneer catheter is a reliable device which may be helpful for achieving target lumen reentry in subintimal recanalization of chronic occlusions and in fenestration of aortic dissections.

Governor Tom Judge: Early Years - The Path to Becoming Montana's 18th Governor -- Sidney Armstrong, Larry Pettit & Kent Kleinkopf “In the Crucible of Change”

The dramatic period of progressive change in Montana that is documented "In the Crucible of Change" series really exploded with the election of Governors Forrest Anderson and Tom Judge. Anderson's single term saw the dispatching of the sales tax as an issue for a long period, the reorganization of the executive branch of state government and the revision of Montana's Constitution. As a former legislator, county attorney, Supreme Court justice, and Attorney General, Anderson brought unmatched experience to the governorship when elected. Tom Judge, although much younger (elected MT’s youngest governor at age 38 immediately following Anderson), also brought serious experience to the governorship: six years as a MT State Representative, two years as a MT State Senator, four years is Lieutenant Governor and significant business experience. The campaign and election of John F. Kennedy in 1960 spurred other young Americans to service, including Tom Judge. First elected in 1960, he rose rapidly through MT’s political-governmental hierarchy until he took over the governorship in time to implement many of the changes started in Governor Anderson’s term. But as a strong progressive leader in his own right, Governor Judge sponsored and implemented significant advancements of his own for Montana. Those accomplishments, however, are the subject of other films in this series. This film deals with Tom Judge’s early years – his rise to the governorship from when he returned home after college at Notre Dame and newspaper experience in Kentucky to his actual election in November 1972. That story is discussed in this episode by three major players in the effort, all directly involved in Tom Judge’s early years and path to the governorship: Sidney Armstrong, Larry Pettit and Kent Kleinkopf. Their recollections of the early Tom Judge and the period of his advancement to the governorship provide an insider’s perspective of the growth of this significant leader of the important period of progressive change documented “In the Crucible of Change.” Sidney Armstrong, President of Sidney Armstrong Consulting, serves on the board and as the Executive Director of the Greater Montana Foundation. Formerly Executive Director of the Montana Community Foundation (MCF), she has served on national committees and participated in national foundation initiatives. While at MCF, she worked extensively with MT Governors Racicot and Martz on the state charitable endowment tax credit and other endowed philanthropy issues. A member of MT Governor Thomas L. Judge’s staff in the 1970s, she was also part of Governor Brian Schweitzer’s 2004 Transition Team, continuing to serve as a volunteer advisor during his term. In the 1980s, Sidney also worked for the MT State AFL-CIO and the MT Democratic Party as well as working two sessions with the MT Senate as Assistant Secretary of the Senate and aide to the President. A Helena native, and great granddaughter of pioneer Montanans, Sidney has served on numerous nonprofit boards, and is currently a board member for the Montana History Foundation. Recently she served on the board of the Holter Museum of Art and was a Governor’s appointee to the Humanities Montana board. She is a graduate of the International School of Geneva, Switzerland and the University of Montana. Armstrong's Irish maternal immigrant great-grandparents, Thomas and Maria Cahill Cooney, came to Virginia City, MT in a covered wagon in 1865, looking for gold. Eventually, they settled on the banks of the Missouri River outside Helena as ranchers. She also has roots in Butte, MT, where her journalist father's family, both of whom were newspaper people, lived. Her father, Richard K. O’Malley, is also the author of a well-known book about Butte, Mile High, Mile Deep, recently re-published by Russell Chatham. She is the mother of four and the grandmother of eight. Dr. Lawrence K. Pettit (Larry Pettit) (b. 5/2/1937) has had a dual career in politics and higher education. In addition to being Montana’s first Commissioner of Higher Education (the subject of another film in this series); Pettit, of Lewistown, served as legislative assistant to U.S. Senators James E. Murray and Lee Metcalf, campaign manager, head of transition team and assistant to Montana Governor Thomas L. Judge; taught political science at The Pennsylvania State University (main campus), was chair of political science at Montana State University, Deputy Commissioner for Academic Programs at the Texas Higher Education Coordinating Board, Chancellor of the University System of South Texas (since merged with Texas A&M University), President of Southern Illinois University, and President of Indiana University of Pennsylvania from where he retired in 2003. He has served as chair of the Commission on Leadership for the American Council on Education, president of the National Association of (University) System Heads, and on many national and state boards and commissions in higher education. Pettit is author of “If You Live by the Sword: Politics in the Making and Unmaking of a University President.” More about Pettit is found at http://www.lawrencekpettit.com… Kent Kleinkopf of Missoula is co-founder of a firm with a national scope of business that specializes in litigation consultation, expert vocational testimony, and employee assistance programs. His partner (and wife of 45 years) Kathy, is an expert witness in the 27 year old business. Kent received a BA in History/Education from the University of Idaho and an MA in Economics from the University of Utah. The Kleinkopfs moved to Helena, MT in 1971 where he was Assistant to the Commissioner of State Lands (later Governor) Ted Schwinden. In early 1972 Kent volunteered full time in Lt. Governor Tom Judge’s campaign for Governor, driving the Lt. Governor extensively throughout Montana. After Judge was elected governor, Kent briefly joined the staff of Governor Forrest Anderson, then in 1973 transitioned to Judge’s Governor’s Office staff, where he became Montana’s first “Citizens’ Advocate.” In that capacity he fielded requests for assistance from citizens with concerns and information regarding State Agencies. While on the Governor’s staff, Kent continued as a travel aide with the governor both in Montana and nationally. In 1977 Kent was appointed Director of the MT Department of Business Regulation. That role included responsibility as Superintendent of Banking and Chairman of the State Banking Board, where Kent presided over the chartering of many banks, savings and loans, and credit unions. In 1981 the Kleinkopfs moved to Missoula and went into the business they run today. Kent was appointed by Governor Brian Schweitzer to the Board of the Montana Historical Society in 2006, was reappointed and continues to serve. Kathy and Kent have a daughter and son-in-law in Missoula.

Remembering Lee Metcalf

Abstract Montana's Lee Metcalf was an extraordinary Montana leader with an unbelievable record of accomplishment fighting for the little people against the forces of economic and political power. The public memory is so short that this film will serve to help reacquaint Lee & Donna Metcalf to most of those who were around during their time. But it will also provide an opportunity for new generations to receive a perspective of an important leader from an important time. (Language from YouTube version of the film, written and provided by Executive Producer Evan Barrett) Lee Warren Metcalf (January 28, 1911 – January 12, 1978) was an American lawyer, judge, and politician. A member of the Democratic Party, he served as a U.S. Representative (1953–1961) and a U.S. Senator (1961–1978) from Montana. He was permanent acting President pro tempore of the Senate, the only person to hold that position, from 1963 until his death in 1978. U.S. House of Representatives During his tenure in the House, Metcalf served on the Education and Labor Committee (1953–1959), Interior and Insular Affairs Committee (1955–1959), Select Astronautics and Space Exploration Committee (1958), and Ways and Means Committee (1959–1960). He became known as one of Congress's "Young Turks" who promoted liberal domestic social legislation and reform of congressional procedures. He introduced legislation to provide health care to the elderly ten years before the creation of Medicare. He earned the nickname "Mr. Education" after sponsoring a comprehensive bill providing for federal aid to education. He also voted against legislation that would have raised grazing permits on federal lands, and led the opposition to a bill that would have swapped forested public lands for cutover private lands. He was elected chairman of the Democratic Study Group in 1959. U. S. Senate Regarded as "a pioneer of the conservation movement", Metcalf worked to protect the natural environment and regulate utilities. He helped pass the Wilderness Act of 1964, and supported the creation of the Great Bear Wilderness and the Absaroka-Beartooth Wilderness. In 1962, he introduced a "Save Our Streams" bill to preserve natural recreation facilities and protect fish and wildlife from being destroyed by highway construction. He was a longtime member of the Migratory Bird Conservation Commission. He was also active on the issue of education. He was a leading supporter of the Elementary and Secondary Education Act, the effort to extend the G.I. Bill's educational benefits to a new generation of veterans, and the development of legislation to improve federally-aided vocational education.[1] The Peace Corps was established under leadership of Metcalf and Senator Mansfield. In 1983, by act of Congress, the Lee Metcalf Wilderness area was created in southwestern Montana in honor of the late Congressman. The Great Bear Wilderness and Absaroka-Beartooth Wilderness areas were also created as a result of Metcalf's efforts in Congress, in addition to the Lee Metcalf National Wildlife Refuge in Montana. Metcalf was ranked number 15 on a list of the 100 Most Influential Montanans of the Century by the Missoulian newspaper.

René Sand (1877-1953) and His Contribution to International Social Work, IASSW-President 1946 – 1953

The extraordinary significance of the life and work of René Sand lies in his central position as a mediator, promoter and coordinator of social work on an increasingly international level during the interwar-period and it can hardly be overestimated. To approach the achievements of Sand’s life and work you have to work archaeologically as he does not seem to have left any traces in the literature on social history. In Germany, even within the field of social work his name is hardly known. His biographical sketch and his importance for the development of the profession of social work have fallen into oblivion. The situation is a little different in the French-speaking countries where a biography has been published (compare Anciaux 1988a, b, c) which contains a detailed record of Sand’s writings. Altogether this lack of interest is regrettable because it doesn’t consider that René Sand is exemplary and in some parts fundamental to the emergence of professional social work in the 1920s in Belgium and Europe. Professional social work was established by a consequent international orientation and an emancipation from neighbouring fields such as social medicine and hygiene. Therefore it is a rewarding task to draw attention to this pioneer of social work and make the public appreciate his work. I want to emphasize explicitly that in this portrait Sand’s achievements concerning social work will be the main focus, even if this is an inevitable reduction of his accomplishments in the field of medicine and social medicine.

Dame Eileen Younghusband (Jan. 1902 - May 1981)

Dame Eileen Younghusband died in a car accident on a lecture tour in the in the USA at a point when preparations had commenced for her 80th Birthday celebrations. Her working life had spanned a significant era in the history of the development of social work and education for the profession in the UK and more widely; and she herself had made a major contribution to these developments. She differs from earlier pioneering figures presented in these historical portraits in representing 'the next generation' of significant women in the history of social work. Nevertheless, she was a pioneer in the sense of initiating radical changes as described later in this portrait.

Walter Friedländer (1891-1984) – Between Social Democracy and Social Darwinism

If the profession of social work is to have a future we must know where it came from, and the series of portraits of our pioneers is one of the paths into the origins of that profession. I feel grateful to the publishers for this online-journal and also honoured to be asked to continue the series on pioneers in social work. I gladly comply because, in connection with my research on Alice Salomon and other social workers who were expelled from Germany and other Nazi-occupied territories (Wieler1989 and 1995) I had the pleasure and privilege of meeting and interviewing Walter Friedländer shortly before he passed away. It is years ago that I visited him in his home among stacks of books and piles of papers. My memories are vivid. I still see his sparkling eyes and hear his soft voice with a very heavy German accent. I was most impressed by his memory of historical events and people which, it seemed, only a large hard-drive could retain these days. Now, I wish I had asked more questions but instead, we will have to rely largely on primary and secondary literature and box upon box of archival materials. I draw heavily on the comprehensive German and Jewish Intellectual Emigré Collection (http://library.albany.edu/speccoll/findaids/ger003.htm) which consists of nearly 50 cubic feet and another collection of the German Central Institute („Deutsches Zentralinstitut für Soziale Fragen-DZI“) in Berlin (www.dzi.de). Some of the more current archival materials were lost in a flood, and much of Friedländer’s early memorabilia up to 1933 was lost in Germany. There are also internet resources with widely differing information. I hope that I will not have overlooked too much in order to do justice to this remarkable pioneer and colleague. In order to appreciate and pay tribute to Walter Friedländer and his contributions we will have to reconsider the historical and international context of more than the 93 years of his life span: the German Monarchy, the Weimar Republic, Nazi-Fascism, Swiss, French and American exile and numerous visits to other countries.

Digital First Sale Doctrine Ante Portas – Exhaustion in the Online Environment

The purpose of the article is to provide first a doctrinal summary of the concept, rules and policy of exhaustion, first, on the international and EU level, and, later, under the law of the United States. Based upon this introduction, the paper turns to the analysis of the doctrine by the pioneer court decisions handed over in the UsedSoft, ReDigi, the German e-book/audio book cases, and the pending Tom Kabinet case from the Netherlands. Questions related to the licence versus sale dichotomy; the so-called umbrella solution; the “new copy theory”, migration of digital copies via the internet; the forward-and-delete technology; the issue of lex specialis and the theory of functional equivalence are covered later on. The author of the present article stresses that the answers given by the respective judges of the referred cases are not the final stop in the discussion. The UsedSoft preliminary ruling and the subsequent German domestic decisions highlight a special treatment for computer programs. On the other hand, the refusal of digital exhaustion in the ReDigi and the audio book/e-book cases might be in accordance with the present wording of copyright law; however, they do not necessarily reflect the proper trends of our ages. The paper takes the position that the need for digital exhaustion is constantly growing in society and amongst businesses. Indeed, there are reasonable arguments in favour of equalizing the resale of works sold in tangible and intangible format. Consequently, the paper urges the reconsideration of the norms on exhaustion on the international and EU level.

Nutritive Value of the Crop Residues from bt-Corn Hybrids and Their Effects on Performance of Grazing Beef Cows

One non bt-corn hybrid (Pioneer 3489) and three btcorn hyrids (Pioneer 34RO7, Novartis NX6236, and Novartis N64-Z4) were planted in replicated 7.1-acre fields. After grain harvest, fields were stocked with 3 mature cows in midgestation to be strip-grazed as four paddocks over 126 days. Six similar cows were allotted to replicated drylots. All cows were fed hay as necessary to maintain a condition score of 5 on a 9-point scale. Cows were condition-scored biweekly and weighed monthly. Forage yield and weathering losses were determined by sampling one 4-m2 location per grazed or ungrazed paddock in each field with a minimum total of 2 locations of grazed or ungrazed forage per field. To measure forage selection during grazing, samples of grazed forage were collected from the rumen of one fistulated steer that grazed for 2 hours after ruminal evacuation. Non-bt-corn hybrids had greater (P<.05) infestation of corn borers in the upper stalk, lower stalk and ear shank than bt-corn hybrids. However, there were no differences in grain yields or dropped grain between hybrids. Crop residue dry matter, organic matter and in vitro digestible dry matter yields at the initiation of grazing did not differ between corn hybrids. Dry matter, organic matter and in vitro digestible dry matter losses tended (P<.10) to be greater from the NX6236 and N64-Z4 hybrids than from the 3489 and 34RO7 hybrids and were greater (P<.05) from grazed than non-grazed areas of the fields. At the initiation of grazing, dry matter concentrations of the crop residues from the NX6236 and N64-Z4 hybrids tended to be lower than those from the 3489 and 34RO7 hybrids. Crop residues from the NX6236 and N64-74 hybrids had lower concentrations of acid detergent fiber (P<.05) and acid detergent lignin (P=.07) and higher concentrations of in vitro digestible organic matter than the 3489 and 34RO7 hybrids. Over the grazing season, corn hybrid did not affect mean rates of change in forage composition. The concentration of in vitro digestible organic matter in forage selected by steers after two weeks of grazing did not differ. However, steers grazing corn crop residues consumed forage with higher (P<.05) concentrations of neutral detergent fiber, acid detergent fiber, and acid detergent insoluble nitrogen than steers fed hay. The acid detergent fiber concentration of forage selected by steers grazing the 3489 and N64-Z4 hybrids was lower (P < .05) than concentrations from the 34RO7 and NX6236 hybrids. In order to maintain similar body condition score changes, cows grazing crop residues from the 3489, 34RO7, NX6236, and N64-Z4 hybrids required 650, 628, 625, and 541 kg hay DM/cow compared with a hay requirement of 1447 kg hay DM/cow for cows maintained in a drylot.

Bone-Conditioned Medium Inhibits Osteogenic and Adipogenic Differentiation of Mesenchymal Cells In Vitro

BACKGROUND AND PURPOSE Autografts are used for bone reconstruction in regenerative medicine including oral and maxillofacial surgery. Bone grafts release paracrine signals that can reach mesenchymal cells at defect sites. The impact of the paracrine signals on osteogenic, adipogenic, and chondrogenic differentiation of mesenchymal cells has remained unclear. MATERIAL AND METHODS Osteogenesis, adipogenesis, and chondrogenesis were studied with murine ST2 osteoblast progenitors, 3T3-L1 preadipocytes, and ATDC5 prechondrogenic cells, respectively. Primary periodontal fibroblasts from the gingiva, from the periodontal ligament, and from bone were also included in the analysis. Cells were exposed to bone-conditioned medium (BCM) that was prepared from porcine cortical bone chips. RESULTS BCM inhibited osteogenic and adipogenic differentiation of ST2 and 3T3-L1 cells, respectively, as shown by histological staining and gene expression. No substantial changes in the expression of chondrogenic genes were observed in ATDC5 cells. Primary periodontal fibroblasts also showed a robust decrease in alkaline phosphatase and peroxisome proliferator-activated receptor gamma (PPARγ) expression when exposed to BCM. BCM also increased collagen type 10 expression. Pharmacologic blocking of transforming growth factor (TGF)-β receptor type I kinase with SB431542 and the smad-3 inhibitor SIS3 at least partially reversed the effect of BCM on PPARγ and collagen type 10 expression. In support of BCM having TGF-β activity, the respective target genes were increasingly expressed in periodontal fibroblasts. CONCLUSIONS The present work is a pioneer study on the paracrine activity of bone grafts. The findings suggest that cortical bone chips release soluble signals that can modulate differentiation of mesenchymal cells in vitro at least partially involving TGF-β signaling.

"Progressiver Islam" im ausgehenden Zarenreich: Das Plädoyer des St. Petersburger Imams und Regierungsbeamten Ataulla Bajazitov (1846-1911) für die Partizipation der Muslime an der modernen Zivilisation

Ataulla Bajazitov (1846-1911) fulfilled a social double role by serving his Tatar community in St. Petersburg as imam and the Russian state as military Muslim ‘cleric’, translator and teacher. By founding Russia’s first monolingual Tatar newspaper, initiating St. Petersburg’s first Friday mosque and presenting scriptural and rational arguments for the compatibility of Islam and the modern Civilization to a Russian-speaking public as early as 1883, he has been a pioneer among the Muslims in Russia in several respects. In contrast though to similar activities of his Russian contemporary, the Krim Tatar Ismail Gasprinskii (1851-1914), Bajazitov’s endeavours have remained almost unnoticed in Western scholarship. Also in Tatarstan, his books have been only recently reprinted. The present study analyzes Bajazitov’s three monographs written in Russian, namely A Response to Ernest Renan’s lecture “Islam and Science” (1883), The Relationship of Islam towards Science and People of Different Faith (1887) and Islam and Progress (1898). There, he exposes many positions that around that time started to become key arguments of Muslim reformers in the Near East for the progressivness of Islam. The study takes also into account reactions to Bajazitov’s monographs by Russian officers in Tashkent who tried to demonstrate the backwardness of Islam, especially Nikolai Petrovič Ostroumov’s (1846-1930) response in his book entitled Quran and Progress – On the intellectual awakening of today’s Russian Muslims (1901/1903).
