We investigated a possible link between endometriosis and polymorphism of the progesterone receptor gene (PROGINS). The endometriosis group consisted of 54 patients with a diagnosis of endometriosis by laparoscopy, and the control group comprised 44 women without endometriosis. Genotypes for PROGINS polymorphisms (A1/A1, A1/A2 and A2/A2) were determined by polymerase chain reaction and analyzed...

Let ∆(a1, a2, · · · , an) be an n-dimensional real simplex with vertices at (a1, 0, · · · , 0), (0, a2, · · · , 0), · · · , (0, 0, · · · , an). Let P(a1,a2,··· ,an) be the number of positive integral points lying in ∆(a1, a2, · · · , an). In this paper we prove that n!P(a1,a2,··· ,an) ≤ (a1 − 1)(a2 − 1) · · · (an − 1). As a consequence we have proved the Durfee conjecture for isolated weighted ...

Let Pn denote the set of all algebraic polynomials of degree at most n with real coefficients. Associated with a set of poles {a1, a2, . . . , an} ⊂ R\ [−1, 1] we define the rational function spaces Pn(a1, a2, . . . , an) := 8< : : f(x) = b0 + n X j=1 bj x− aj , b0, b1, . . . , bn ∈ R 9= ; . Associated with a set of poles {a1, a2, . . . } ⊂ R\[−1, 1] , we define the rational function spaces P(a...

Phospholipase A2 (PLA2) constitutes a diverse superfamily of enzymes which catalyze the deacylation of phospholipids. At least four types of PLA2 are potentially involved in arachidonic acid release in cells and tissues. Since all of them catalyze the same enzymatic reaction, it is difficult to distinguish between them in mixtures of enzymes normally present in biological samples. Utilizing spe...

Coxsackievirus A2 (CV-A2) has been frequently detected and commonly associated with hand, foot, and mouth disease (HFMD) in China since 2008. However, limited sequences of CV-A2 are currently available. As a result, we have been focusing on the genetic characteristics of CV-A2 in the mainland of China during 2008-2015 based on national HFMD surveillance. In this study, 20 CV-A2 strains were iso...

Telomere extension by telomerase is essential for chromosome stability and cell vitality. Here, we report the identification of a splice variant of mammalian heterogeneous nuclear ribonucleoprotein A2 (hnRNP A2), hnRNP A2*, which binds telomeric DNA and telomerase in vitro. hnRNP A2* colocalizes with telomerase in Cajal bodies and at telomeres. In vitro assays show that hnRNP A2* actively unfol...

Let A2(n) = Γ2(n)\S2 be the quotient of Siegel’s space of degree 2 by the principal congruence subgroup of level n in Sp(4, Z). This is the moduli space of principally polarized abelian surfaces with a level n structure. Let A2(n) ∗ denote the Igusa compactification of this space, and ∂A2(n) ∗ = A2(n) ∗−A2(n) its “boundary”. This is a divisor with normal crossings. The main result of this paper...

Annexins are a family of homologous proteins that associate with anionic phospholipid (aPL) in the presence of Ca(2+). Evidence that the function of one annexin type may be regulated by another was recently reported in studies investigating cytomegalovirus-aPL interactions, where the fusogenic function of annexin 2 (A2) was attenuated by annexin 5 (A5). This observation suggested that A2 may bi...
