Genomic clones of nm23-H1 and -ff2 were isolated. The nm23-H1 and -112 genes were located in a tandem array 4 kilobases apart. Each genome contained 5 exons and most of the splicing sites in the exon-intron junctions of two isotypes were essentially identicaL A probe dertved from intron 4 ofnm23-H1 was used to examine the loss ofheterozygosity (LOH) In primary colorectal carcinomas. Twenty-nine...
If D is C+ or D , then we prove that H1(D) is a Hermite regular coherent ring of weak global dimension 2 (the coherence was already proved in [4]). We show: there is a one-to-one equivalence between systems de ned by matrices with entries in H1(D) and coherent H1(D)-modules, coherent H1(D)-modules are stable by elementary algebraic operations, and thus, we can characterize the algebraic propert...
Applying the methods developed in [3], in [4] we have constructed generalized CS attached to the Jacobi group G1 = H1 oSU(1, 1), based on the homogeneous Kähler manifold D 1 = H1/R × SU(1, 1)/U(1) = C 1 × D1. Here D1 denotes the unit disk D1 = {w ∈ C ; |w| < 1}, and Hn is the (2n + 1)-dimensional real Heisenberg-Weyl group with Lie algebra hn. In [4] we have also emphasized that, when expressed...

We examined the distribution of the somatic subtypes of histone H1 and the variant subtype, H1(0), and their encoding mRNAs during oogenesis and early embryogenesis in the mouse. As detected using immunocytochemistry, somatic H1 was present in the nuclei of oocytes of 18-day embryos. Following birth, however, somatic H1 became less abundant in both growing and non-growing oocytes, beginning as ...
In this paper, we discuss the H1 L -boundedness of commutators of Riesz transforms associated with the Schrödinger operator L =−4+ V , where H1 L (R n) is the Hardy space associated with L . We assume that V (x) is a nonzero, nonnegative potential which belongs to Bq for some q > n/2. Let T1 = V (x)(−4+ V )−1, T2 = V 1/2(−4+ V )−1/2 and T3 =∇(−4+ V )−1/2. We prove that, for b ∈ BMO(Rn), the com...
BACKGROUND We recently reported that autoreactive antibody (Ab) against nuclear histone H1 had been identified as an immunosuppressive factor in a rat tolerogenic orthotopic liver transplantation (OLT) model. The present study aimed to determine whether the up-regulation of antihistone H1 Ab by histone H1 vaccination leads to tolerance. METHODS Histone H1-immunized rats were established by in...
در این پروژه روش های ساده و کارآمدی جهت سنتز ترکیبات هتروسیکل نظیر مشتقات جدیدی از ترکیبات 1,5- دی آریل– 3-(آریل آمینو)-h1-پیرول-(h5)2-اون ها، 3-هیدروکسی اکسیندول ها، 2-آمینو-3-سیانوپیریدین ها، 3-متیل کینوکسالین-2(h1)-اون و 3,6- دی متیل-h2-بنزو[b] ]1,4[اکسازین-2-اون ارائه شده است. از مزایای این روش ها، مطابقت با الگوهای شیمی سبز، نظیر شرایط بدون حلال، بدون کاتالیزور و مدت زمان کم کامل شدن واکنش...
B7-H1 is a recently described B7-like molecule that costimulates T-cell growth and cytokine secretion without binding to CD28, cytotoxic T-lymphocyte antigen-4 (CTLA-4), and inducible costimulator (ICOS). In this report, a mouse homologue of human B7-H1 is identified, and its immunologic functions are studied in vitro and in vivo. Mouse B7-H1 shares 69% amino acid homology to the human counterp...
