A Case of Probable Hepatic Glycogenosis Accompanying Poorly Controlled Type 1 Diabetes Mellitus  [cached]
Elif K?l?? Kan,Gül?in Cengiz Ecemi?,?i?dem Tura Bahad?r,Hulusi Atmaca
Turkish Journal of Endocrinology and Metabolism , 2012,
Abstract: The major causes of hepatomegaly and elevated transaminases in patients with diabetes mellitus are glycogenosis or fatty liver and non-alcoholic steatohepatitis (NASH). Although hepatic glycogenosis is common in this population, hepatomegaly or elevated transaminase are more often attributed to steatosis than to glycogen excess, and so as glycogenosis may be considered a rare cause of these findings. Accordingly, information on adult diabetic patients with glycogen-induced hepatomegaly is scant. The accumulation of excessive amounts of glycogen in the hepatocytes is a consequence of intermittent episodes of hyperglycemia and hypoglycemia and the use of excessive insulin. Hepatic glycogenosis occurs in patients with poorly controlled type 1 or type 2 diabetes; whereas steatosis is associated with obesity and insulin resistance. The distinction between steatosis and glycogenosis is important. Steatosis may progress to fibrosis and cirrhosis, whereas glycogenosis improves dramatically in response to the institution of euglycemic control. In addition, true diagnosis avoids the unnecessary and invasive investigations. We present a case clinically suggesting hepatic glycogenosis that led to symptomatic hepatomegaly and markedly elevated serum aminotransferases in patient with type 1 diabetes mellitus.

Issues in Type IIA Uplifting  [PDF]
Renata Kallosh,Masoud Soroush
Physics , 2006, DOI: 10.1088/1126-6708/2007/06/041
Abstract: Moduli stabilization in the type IIA massive string theory so far was achieved only in the AdS vacua. The uplifting to dS vacua has not been performed as yet: neither the analogs of type IIB anti-D3 brane at the tip of the conifold, nor the appropriate D-terms have been identified. The hope was recently expressed that the F-term uplifting may work. We investigate this possibility in the context of a simplified version of the type IIA model developed in hep-th/0505160 and find that the F-term does not uplift the AdS vacua to dS vacua with positive CC. Thus it remains a challenging task to find phenomenologically acceptable vacua in the type IIA string theory.

Type IIA-Heterotic Duals With Maximal Supersymmetry  [PDF]
S. Chaudhuri,D. A. Lowe
Physics , 1995, DOI: 10.1016/0550-3213(95)00589-7
Abstract: Using finite abelian automorphism groups of $K3$ we construct orbifold candidates for Type IIA-heterotic dual pairs with maximal supersymmetry in six and lower dimensions. On the heterotic side, these results extend the series of known reduced rank theories with maximal supersymmetry. The corresponding Type IIA theories generalize the Schwarz and Sen proposal for the dual of the simplest of the reduced rank theories constructed as a novel Type IIA $\IZ_2$ orbifold.
On the Compactification of Type IIA String Theory  [PDF]
J. Maharana,H. Singh
Physics , 1997, DOI: 10.1016/S0370-2693(97)00823-X
Abstract: The ten-dimensional type IIA string effective action with cosmological constant term is dimensionally reduced on a d-dimensional torus to derive lower dimensional effective action. The symmetries of the reduced effective action are examined. It is shown that the resulting six-dimensional theory does not remain invariant under $SO(4,4)$ symmetry whereas the reduced action, in the absence of the cosmological constant respects the symmetry as was shown by Sen and Vafa. New class of black hole solutions are obtained in five and four dimensions in the presence of cosmological constant. For the six-dimensional theory, a four-brane solution is also presented.
Massive Type IIA Theory on K3  [PDF]
Michael Haack,Jan Louis,Harvendra Singh
Physics , 2001, DOI: 10.1088/1126-6708/2001/04/040
Abstract: In this paper we study K3 compactification of ten-dimensional massive type IIA theory with all possible Ramond-Ramond background fluxes turned on. The resulting six-dimensional theory is a new massive (gauged) supergravity with an action that is manifestly invariant under an O(4,20) / (O(4) times O(20)) duality symmetry. We discover that this six-dimensional theory interpolates between vacua of ten-dimensional massive IIA supergravity and vacua of massless IIA supergravity with appropriate background fluxes turned on. This in turn suggests a new 11-dimensional interpretation for the massive type IIA theory.

Physics , 2000, DOI: 10.1016/S0550-3213(00)00398-9
Abstract: The kappa--invariant worldvolume action for the NS5--brane in a D=10 type IIA supergravity background is obtained by carrying out the dimensional reduction of the M5--brane action.
D=4, N=1, Type IIA Orientifolds  [PDF]
S. Ishihara,H. Kataoka,Hikaru Sato
Physics , 1999, DOI: 10.1103/PhysRevD.60.126005
Abstract: We study D=4, N=1, type IIA orientifold with orbifold group $Z_N$ and $Z_N \times Z_M$. We calculate one-loop vacuum amplitudes for Klein bottle, cylinder and Mobius strip and extract the tadpole divergences. We find that the tadpole cancellation conditions thus obtained are satisfied by the $Z_4$, $Z_8$, $Z'_8$, $Z'_{12}$ orientifolds while there is no solution for $Z_3$, $Z_7$, $Z_6$, $Z'_6$, $Z_{12}$. The $Z_4 \times Z_4$ type IIA orientifold is also constructed by introducing four different configurations of 6-branes. We argue about perturbative versus non-perturbative orientifold vacua under T- duality between the type IIA and the type IIB $Z_N$ orientifolds in four dimensions.
Puzzles on the Duality between Heterotic and Type IIA Strings  [PDF]
Mitsuko Abe,Masamichi Sato
Physics , 1999, DOI: 10.1016/S0370-2693(99)01171-5
Abstract: We discuss the possibility of the extension of the duality between the webs of heterotic string and the type IIA string to Calabi-Yau 3-folds with another K3 fiber by comparing the dual polyhedron of Calabi-Yau 3-folds given by Candelas, Perevalov and Rajesh.
On Orientifold Constructions of Type IIA Dual Pairs  [PDF]
Anindya K. Biswas
Physics , 1996, DOI: 10.1103/PhysRevD.55.2382
Abstract: In this paper we analyze the earlier constructions of the type IIA dual pairs through orientifolding. By an appropriate choice of $\Gamma$-matrix basis for the spinor representations of the $U$-duality group, we give an explicit relationship between the orientifold models and their dual pairs.
