Celiac disease as potential obstacle to childbearing  [PDF]
Mónika Kovács, Mária Szenes, Tihamér Horváth, Gy?rgy Vajda, Beáta Gasztonyi, Gy?rgy Bártfai
Open Journal of Obstetrics and Gynecology (OJOG) , 2014, DOI: 10.4236/ojog.2014.42014
Abstract:

AIM: The authors have aimed at confirming or excluding gluten sensitivity in infertile couples. PATIENTS AND METHODS: Between 2004 and 2010, at our outpatient clinics of immunology, both partners of 223 couples, who had striven for having a child unsuccessfully, underwent history taking, physical examination, laboratory and immuno-serologic tests including anti-tissue-transglutaminase antibody (antitTG), as well as deep duodenal biopsy in antibody-carrying patients. RESULTS: Antibodies against tissue transglutaminase were positive in 6/223 female patients of whom the diagnosis of celiac disease was histologically confirmed in 3/223 cases (1.34%). Of the male patients 2/223 (0.9%) have proven to be carriers of the antibody; histology was pathognomonic in both of them. Curiously, one of the male patients with celiac disease has been the partner of a woman who also had celiac disease diagnosed by the authors. In the followup period, a female patient and the female member of the couple with celiac disease gave birth to healthy newborns after spontaneous conception, as the result of a strictly kept gluten-free diet, as well as occasional treatments of acetylsalicylate for antiphos-pholipid syndrome or levothyroxine for latent hypothyroidism due to autoimmune thyroiditis. CONCLUSION: The results underline that it is worth performing a screening for celiac disease in both partners of couples assessed due to the lack of success in having a child, as infertility can be ceased by an appropriate diet.

Supporting Applications Development and Operation Using IT Security and Audit Measures
Katalin Szenes
e-Informatica Software Engineering Journal , 2012,
Abstract: The market success of the enterprises depends on the ability to support their business processes. This involves the requirement of a seamless, well-ordered operation of the whole company. Operation is greatly affected by the quality of its IT support. The information should be available, handled confidentially, preserving its integrity, have to be processed in a reliable, efficient, effective way, in compliance with the requirements of supervisory authorities. Extending the scope of these information criteria to criteria determining operations quality and adding two business-level requirements to them makes possible to find preventive, detective andcorrective, originally information security control measures, raised to the level of operational quality, that support the market success of the institutions.
The combinatorics of the Verlinde formulas
Andras Szenes
Physics , 1994,
Abstract: A residue formula is given for the Verlinde formula, which allows one to calculate its coefficients as a polynomial in the level and connects it to the Riemann-Roch formula on the moduli space of vector bundles on a curve.
A residue theorem for rational trigonometric sums and Verlinde's formula
Andras Szenes
Mathematics , 2001,
Abstract: We present a compact formula computing rational trigonometric sums. E. Verlinde's expression for the dimension of conformal blocks in WZW theory is an example of such a sum. As an application, we show that a formula of Bismut and Labourie for the Riemann-Roch numbers of moduli spaces of flat connections on a Riemann surface coincides with Verlinde's expression.
Exceptional points for Lebesgue's density theorem on the real line
Andras Szenes
Mathematics , 2007,
Abstract: For a nontrivial measurable set on the real line, there are always exceptional points, where the lower and upper densities of the set are neither zero nor one. We quantify this statement, following work by V. Kolyada, and obtain the unexpected result that there is always a point where the upper and the lower densities are closer to 1/2 than to zero or one. The method of proof uses a combinatorial restatement of the problem.
Periodicity of Y-systems and flat connections
Andras Szenes
Mathematics , 2006,
Abstract: We give a proof of the periodicity of Zamolodchikov's Y-systems in the AxA case using a novel interpretation of the system as a condition of flatness of a connection on a certain graph.
Iterated Residues and Multiple Bernoulli Polynomials
Andras Szenes
Mathematics , 1997,
Abstract: We describe an effective method for calculating certain infinite sums, generalizations of the classical Bernoulli polynomials. As shown by Edward Witten in his papers on two-dimensional gauge theories, the correlation functions of two-dimensional topological Yang-Mills theory (or intersection numbers on moduli spaces of flat connections) can be given in the form of such infinite sums. Thus, in particular, our results give finite expressions for these correlation functions in the case of arbitrary compact structure groups G.
Crystal bases, dilogarithm identities and torsion in algebraic K-groups
Edward Frenkel,Andras Szenes
Physics , 1993,
Abstract: We give a new interpretation and proof of the dilogarithm identities, associated to the affine Kac-Moody algebra sl(2)^, using the path description of the corresponding crystal basis. We also discuss connections with algebraic K-theory.
Dilogarithm identities, q-difference equations and the Virasoro algebra
Edward Frenkel,Andras Szenes
Physics , 1992,
Abstract: We give a new proof of the dilogarithm identities, associated to the (2,2n+1) minimal models of the Virasoro algebra.
Thom polynomials of Morin singularities
Gergely Berczi,Andras Szenes
Mathematics , 2006,
Abstract: We prove a formula for Thom polynomials of Morin (or A_d) singularities in any codimension. We use a combination of the test-curve method of Porteous, and the localization methods in equivariant cohomology. Our formulas are independent of the codimension, and they are computationally efficient for d less than 7.
