SIRT and Its Unresolved Problems—Is Imaging the Solution? A Review  [PDF]
Franziska Schulz, Michael Friebe
Journal of Cancer Therapy (JCT) , 2016, DOI: 10.4236/jct.2016.77054
Abstract: Selective Internal Radiation Therapy (SIRT) is used as a treatment option for unresectable liver tumors. In SIRT, microspheres, which have a radioactive substance as an integral component, are placed via image guided catheters into the hepatic artery. The ionizing radiation is directly delivered to the tumor. Currently used commercially available microspheres are based on Yttrium 90, a β-emitter, which has been shown to be safe and to produce good clinical results. The technical features of Y90, their applications and their limitations are presented. Image guidance and intraoperative depiction of Yttrium 90 microspheres are restricted, which is currently one of the main limitations in SIRT. Therapy planning and control is currently based on pre- and post-operative images to evaluate the placement of the microspheres respectively. Holmium 166, another possible nuclide integrated into the microspheres emits a higher amount of secondary γ-radiation (Bremsstrahlung) than Yttrium 90. This enables an improved depiction of the microspheres inside the patient during and immediately after application, but comes with other shortfalls. Imaging of delivery and verification of the microsphere placement could solve many of the identified problems with SIRT. The different technologies are reviewed and an outlook in future developments is given particularly on image guidance and therapy control.
The Game of Life, Decision and Communication  [PDF]
Roland Mühlenbernd, Simon Schulz
Natural Science (NS) , 2014, DOI: 10.4236/ns.2014.613097

The game of life represents a spatial environment of cells that live and die according to fixed rules of nature. In the basic variant of the game a cell’s behavior can be described as reactive and deterministic since each cell’s transition from an actual state to a subsequent state is straight-forwardly defined by the rules. Furthermore, it can be shown that the alive cells’ spatial occupation share of the environment decreases quickly and levels out at a really small value (around 3%), virtually independent of the initial number of alive cells. In this study we will show that this occupation share can be strongly increased if alive cells become more active by making non-deterministic sacrificial decisions according to their individual positions. Furthermore, we applied signaling games in combination with reinforcement learning to show that results can be even more improved if cells learn to signal for navigating the behavior of neighbor cells. This result stresses the assumption that individual behavior and local communication supports the optimization of resourcing and constitute important steps in the evolution of creature and man.


La cuestión del ser y la Trinidad
Teología y vida , 2009, DOI: 10.4067/S0049-34492009000100012
Abstract: in the light of revelation regarding the trinity, the swiss theologian hans urs von balthasar posits the question of being. his ontology underlines the positivity of being: the characteristics of being, characterisitcs that metaphysical tradition identified with the deficiency of finite being in comparison to the being of god, balthasar, in constrast to this tradition, interprets them as indicators that show the similarity of being with the trinity: difference, alterity, receptivity, passivity. the author of the present article concludes that, without ontology, the rational justification of the possibility of a definitive revelation of god remains difficult. in this way, recurring to the apagogic proof, the ontological dimension of this thought is shown.
Tratamento das dislipidemias: como e quando indicar a combina??o de medicamentos hipolipemiantes
Schulz, Isio;
Arquivos Brasileiros de Endocrinologia & Metabologia , 2006, DOI: 10.1590/S0004-27302006000200021
Abstract: familial combined hyperlipidemia (fch) is a frequent familial lipid disorder associated with insulin resistance, low hdl cholesterol, high triglycerides and cholesterol levels with variable phenotypes within the same family. fch is linked to a high risk for cardiovascular diseases. treatment goals for lipid abnormalities are changing in recent years. lowering elevated levels of ldl e non hdl-cholesterol levels are primary targets of therapy. lower ldl-c than 70 mg/dl seems to be useful to lower cardiovascular risk in patients with very high risk. many statins are available, with different potencies and drug interactions. combination therapy of statins and bile acid sequestrants or ezitimibe may be necessary to further decrease ldl cholesterol levels in order to meet guideline goals. high triglycerides and low hdl cholesterol are also important goals in the treatment of these patients, and frequently statins alone are insufficient to normalize the lipid profile. combination therapy with fibrates will further lower triglycerides and increase hdl cholesterol levels; this combination is also associated with higher incidence of myopathy and liver toxicity; appropriate evaluation of patients' risk and benefits is necessary. association of statin/niacin seems be very useful in patients with fch, especially as niacin is the best drug to increase hdl cholesterol; this association is not linked to a higher frequency of myopathy. niacin causes flushing, that can in part be managed with use of aspirin and extended release forms (niaspan); niacin also may increase plasma glucose and uric acid levels. evaluation of risks and benefits for each patient is needed.

Service vor Ort – Die Bibliothek geht zum Nutzer / On-site service – The library goes to the user
Schulz, Manuela
GMS Medizin-Bibliothek-Information , 2010,
Abstract: Among the core activities of libraries are user orientated services which nowadays imply the reflection about the services and their permanent enhancement. In a medical university library different user groups with special needs can be identified: students, physicians, researchers, nursing and laboratory staff, as well as administration staff. While students continuously make use of the library services on-site, researchers and physicians use or would like to use the electronic resources predominantly from their workplace. The article deals with the problematization, needs assessment and conceptual design of a service model for reaching all potential user groups that can be found in the Library for the Medical Faculty of Mannheim.

The Johannes a Lasco Library Emden – on the Way to a Self- supporting Library
Walter Schulz
Liber Quarterly : The Journal of European Research Libraries , 2000,
Abstract: The focus of this conference is new library architecture, so in my short lecture I will describe our new building and explain how it works. But to understand the special situation of the Emden library it is quite important to know the special and that means too the historical backround and to see the different ways we use the library - really uncommon for a church-library. Most of the libraries represented at this conference are university or state libraries. The Emden library project is not comparable to most of them. The Johannes a Lasco Library was for centuries the book collection only of the reformed communitiy at Emden and just the last ten years we started to build up a compehensive special-library in the field of reformed protestantism on the basis of this old collection, not a particularly large but a well sorted specified one. Today the library is organized as a foundation or registered charity according to German law and belongs to the Reformed Church of Germany.

Bezbednosni Dijalozi , 2010,
Abstract: This study has examined Palestinians’ readiness to compromise over thekey issues of the Israeli-Palestinian conflict. In contrast to existing opinion poll results the claim that Palestinians support a territorial compromise over historical Palestine, this study indicates a radicalization of Palestinian attitudes. Four survey studies, conducted in 1997, 2001, 2006 and 2009, reveal that Palestinian support for a two-state solution have decreased at the expense of an increased preference for an Islamic state in the whole of historical Palestine. Also, Palestinians do not believe that peace with Israel can be achieved in the near future, and are ready to continue their struggle against Israeli occupation in the West Bank. The study also reveals that Palestinians are becoming increasingly isolated and hence less exposed to alternative strategies in the conflict with Israel. These attitudinal changes follow the negative developments in the peace process and the violence that eruptedbetween Israelis and Palestinians in September 2000. Consequently, the lack of current public pressure on the Palestinian leadership to find a political compromise with Israel risks continued deadlock in the conflict. These changes also partly explain why Palestinians voted the Hamas movement into power in the January 2006 election.
