Myobakteriennachweis aus Geweben des Urogenitaltraktes

Abstract: Mit 24,1 % steht die Urogenitaltuberkulose (UGT) auch 1997 in Deutschland unver ndert an zweiter Stelle der extrapulmonalen Tuberkulosen nach der Tuberkulose der peripheren Lymphknoten. In 25-30 % der F lle kann die Diagnose UGT nur aus dem histologischen Bild und/oder dem Nachweis von Mycobacterium tuberculosis-Komplex durch PCR gestellt werden. Aussagen zur biologischen Aktivit t der Tuberkulose sind jedoch nur durch kulturelle Züchtung von Mykobakterien m glich. Deshalb wurde versucht, aus 118 Gewebsproben von Patienten mit UGT mit bakteriologischen Methoden (Mikroskopie, Kultur, Tierversuch) Mykobakterien nachzuweisen und zu isolieren. Insgesamt konnten aus 24 von 118 Proben (20,3 %) Mykobakterien gezüchtet werden (Kultur / Tierversuch). Bei den Nierengewebsproben waren nach durchschnittlich 3-monatlicher antituberkul ser Behandlung in 35 % der F lle noch Mykobakterien nachweisbar. Diese Ergebnisse zeigen, da der biologische Nachweis von Mykobakterien aus Geweben die diagnostische Treffsicherheit verbessern kann, und da bei der UGT eine antituberkul se Chemotherapie von mindestens 6 Monaten erforderlich ist.

Positive Energy Wormholes Made from Normal Charges
Ron Lenk
Physics , 2010,
Abstract: In this article we look at the class of positive-energy density wormholes introduced by Eiroa and Simeone, and ask the question "How close can we come to building this wormhole with normal, electrically charged matter?" Using a series expansion, we determine that the stress-energy tensor of the metric can be made arbitrarily close to that of a charged line-source by taking the exponent of the radial coordinate to be sufficiently small. We also find terms in the expansion which resemble QED radiative corrections to the Coulomb field of an electron.
Classical Electron Model with QED Corrections
Ron Lenk
Physics , 2010,
Abstract: In this article we build a metric for a classical general relativistic electron model with QED corrections. We calculate the stress-energy tensor for the radiative corrections to the Coulomb potential in both the near-field and far-field approximations. We solve the three field equations in both cases by using a perturbative expansion to first order in alpha (the fine-structure constant) while insisting that the usual (+, +, -, -) structure of the stress-energy tensor is maintained. The resulting metric models a (non-spinning) electron with a Coulomb potential with QED corrections, and maintains masslessness of the photon to self-consistent order. The near-field solution resembles the metric of a global monopole.
General Exact Solution of Einstein Field Equations for Diagonal, Vacuum, Separable Metrics
Ron Lenk
Physics , 2010,
Abstract: In this article we find the general, exact solution for the gravitational field equations for diagonal, vacuum, separable metrics. These are metrics each of whose terms can be separated into functions of each space-time variable separately. Other than this, the functions are completely arbitrary; no symmetries are assumed; no limitations are placed on the coordinates. There are 16 functions, which with specific selection of coordinates reduce to 12. Since there are 10 field equations, two functions in the solution are completely arbitrary. The field equations are solved exactly. The solution for each function is presented analytically, with a total of three parameters and ten constants in addition to the two arbitrary functions.
Synchronized clocks and time on a rotating disc
Richard Lenk
Physics , 2013,
Abstract: Basic for the definition of 'time' are clocks operating under stationary conditions. The periods of two clocks can be compared with each other via two return experiments. The central clock mediates between the rotating and the inertial frame. Dimensional arguments and a detailed deduction show that the period of a rotating clock, measured externally in the inertial system, is the same as the internally defined one. There is a common synchron-time, especially 'absolute' simultaneity and invariance of flight times hold. This allows a new discussion of the twin problem. The invariance of a rotating circle allows the transference of the inertial polar coordinates to the rotating plane. The flight time of a light pulse obeys a generalized Fermat's principle. If rays are well defined, this time of flight determines the phase shift of the wave and the result of interference experiments. All general considerations and proofs are independent of the relativity theory, especially of the concept of local inertial systems and differential-geometrical techniques.
Allium hookeri, Thw. Enum. A lesser known terrestrial perennial herb used as food and its ethnobotanical relevance in manipur

Abstract: Manipur, one of the north-eastern states of India, is rich in plant diversity and the natives of Manipur have ethnobotanical and traditional knowledge of plants. The rich traditional knowledge of plants is the outcome of a number of hit and trial selections of plants from the wilderness, for consumption and traditional healing of various ailments. In spite of the risk of selection, the diverse food plants provide the required nutrient supplements; as a result deficiency or malnutrition related diseases were uncommon with the Manipuris. Almost all the world renowned sportspersons of Manipur come from poor families who depend on the traditional and indigenous food plants. Many of the plants act as important nutraceuticals, possessing the medicinal properties. Today, due to over exploitation and under production of indigenous food plants, the lifestyles of the people are changed and they prefer ‘junk foods’. Subsequently, the health of the people is deteriorating as the indigenous/traditional food plants are neglected at large. The plant is used as spice/condiment in dry or in fresh form in every household in almost all the traditional dishes. It acts as a good supplementary food, providing food security at the household level and help at the time of food crisis. The cultivation of this wild plant (now cultivated to a limited extent) not only generates income for the growers but also helps in the conservation of the plants and their germplasm. In spite of the immense use, Allium hookeri cultivation and its preservation has been decreased due to lack of research-based information of the plant, and due to the concept that wild/traditional plants are poor in nutrition and meant only for the poor. Moreover, agriculturalists and farmers take interest in the cultivation of only the high yielding few cash crops and vegetables. From the result of biochemical analyses, the field survey report and the information from literature, it is known that the plant is fit for consumption and has ethnobotanical relevance. The result of the survey in the urban markets and the rural vendors shows that Allium hookeri, Thw. Enum. is of high socio-economical relevance.
Uncertainty in Less Developed Countries in the Face of Crisis

African Research Review , 2012,
Abstract: The global financial crisis that started in September 2007 with a rather limited problem in a market for non-tradeable goods (houses) challenged the way we have been thinking for decades about globalization, development and vulnerability. The crisis confronts social scientist, not just economist, with many issues that need reflection. This article concentrates on the developing and emerging economies in order to gain fresh insight into the challenges that the crisis poses to development strategies and policies. The crisis has serious social outfalls, slowing down the fight against poverty, sometimes increasing poverty, deteriorating income equality and reducing access of social service. This crisis also creates political conflict, generates new sets of priorities (both in the developed and developing economies) threaten food security and illuminates the need for better global governance frameworks. The role of the state as a leading actor in fostering economic growth and well-being has remained for some and emerged for others as a new paradigm. There is no one -size-fit-all strategy, but in this article, there are some proposals for development of LDCs. These countries still have some room to manoeuvre despite their loss of policy space.
