PROBLEM T-helper 2 (TH2)-type cytokines [i.e., interleukin (IL)-6, IL-10, and IL-13] and transforming growth factor (TGF)-beta are expressed by the murine decidua and/or placenta and are likely to suppress inflammatory cytokine [i.e., IL-2, interferon (IFN)-gamma, tumor necrosis factor (TNF)-alpha, IL-1 alpha, and IL-1 beta] production at the maternal-fetal(More)
PROBLEM Communication at the human maternal-fetal interface occurs by an intricate cytokine network. This study examines cytokine expression by normal first-trimester human chorionic villi. METHOD OF STUDY Tissues were obtained at elective pregnancy terminations (7-9 weeks). Total RNA was isolated from chorionic villi by guanidinium isothiocynate-acid(More)
The uterus contains all the components of a tertiary lymphoid compartment. We hypothesize that specific leukocyte recruitment to the endometrium during the secretory phase of the menstrual cycle and early pregnancy limits the type of immunocyte that gains access. The present study utilized flow cytometry to define and quantify adhesion molecules possibly(More)
A fast new algorithm is used compute the zeros of 10 quadratic character L-functions for negative fundamental discriminants with absolute value d > 10. These are compared to the 1-level density, including various lower order terms. These terms come from, on the one hand the Explicit Formula, and on the other the L-functions Ratios Conjecture. The latter(More)
In [1], Bloch constructs symbols in K2(E) for a CM elliptic curve E defined over Q, corresponding to divisors supported on torsion points of the curve. This construction, and the special properties of such curves, allowed him to prove the Beilinson conjecture for such curves. In [2], Deninger extends Bloch’s results, for certain elliptic curves ‘of Shimura(More)
An algorithm is given to efficiently compute, for large discriminant, L-functions of characters on the class group of a complex quadratic field. This is an analog in conductor aspect of the Odlyzko-Schönhage algorithm to compute the Riemann zeta function. Examples are included for about 21000L-functions with conductor near 10. The data shows good agreement(More)
In [6], Odlyzko and Schönhage developed an algorithm to compute the Riemann zeta function ζ(s) efficiently for values of s very high up in the critical strip. Their method depends on precomputation of Taylor series expansions of ζ(s) at regularly spaced points, which in turn can be done efficiently by a clever application of the Fast Fourier Transform.(More)
where D is the product of g primary discriminants (i.e., D has g distinct prime factors). Let p(−D) denote the cardinality of the principal genus P(−D). The genera of forms are the cosets of C(−D) modulo the principal genus, and thus p(−D) is the number of classes of forms in each genus. The study of this invariant of the class group is as old as the study(More)
