Competitive and standard enzyme-linked immunosorbent assays (ELISAs), rose bengal (RB), complement fixation, and agar gel immunoprecipitation with native hapten (AGID-NH) were compared by using sera from Brucella-free, Brucella melitensis-infected, and B. melitensis Rev1-vaccinated sheep. The most sensitive tests were indirect ELISA and RB, and the most specific tests were AGID-NH and competiti...
The retinoblastoma (RB) protein represses global RNA polymerase III transcription of genes that encode nontranslated RNAs, potentially to control cell growth. However, RNA polymerase III-transcribed genes exhibit diverse promoter structures and factor requirements for transcription, and a universal mechanism explaining global repression is uncertain. We show that RB represses different classes ...
Conventionally, signaling through BCR initiates sequence of events necessary for activation and differentiation of B cells. We report an alternative approach, independent of BCR, for stimulating resting B (RB) cells, by involving TLR-2 and CD40--molecules crucial for innate and adaptive immunity. CD40 triggering of TLR-2 stimulated RB cells significantly augments their activation, proliferation...
BACKGROUND Myocardial blood flow (MBF) can be measured with positron emission tomography (PET) and its quantification should provide diagnostic information beyond that obtained through standard visual analysis. However, this possibility has not been fully studied with PET and generator-produced rubidium-82 (⁸²Rb). We evaluated regional MBF in segments with and without ischemia using ⁸²Rb PET in...
Let A and B be two Hopf algebras and R ∈ Hom(B ⊗ A, A ⊗ B), the twisted tensor product Hopf algebra A#RB was introduced by S. Caenepeel et al in [3] and further studied in our recent work [6]. In this paper we give the necessary and sufficient conditions for A#RB to be a Hopf algebra with a projection. Furthermore, a braided Hopf algebra A is constructed by twisting the multiplication of A thro...
Retinoblastoma (Rb)/E2F complexes repress expression of many genes important for G(1)-to-S transition, but also appear to regulate gene expression at other stages of the cell cycle. In C. elegans, lin-35/Rb and other synthetic Multivulva (SynMuv) group B genes function redundantly with other sets of genes to regulate G(1)/S progression, vulval and pharyngeal differentiation, and other unknown p...
آب ترکیب حیاتی مهمی برای زندگی انسان و منبع ضروری برای تولید مواد غذایی، لباس و حفظ بهداشت و محیط زیست است. بنابراین، دسترسی به آب آشامیدنی سالم در سراسر جهان بسیار مهم است. در این مقاله، ابتدا نانوکامپوزیت زیستسازگار پلی(N-وینیل پیرولیدون–کو-مالئیک انیدرید)-سبوس برنج با استفاده از مونومرهای مالئیک انیدرید و N -وینیل پیرولیدون در مجاورت نانوذرات سبوس برنج با روش پلیمرشدن رادیکالی درجا سنتز شد....
As an initial step in evaluating the role of tumor suppressor genes in leukemogenesis, we surveyed primary leukemia cells from 130 patients for possible deletion of the retinoblastoma susceptibility (Rb) gene by Southern blot analysis. Two of them clearly showed homozygous deletion of Rb alleles. The first patient was a pre-B acute lymphoid leukemia (ALL) associated with a cytogenetic transloca...
The notion of a tensor product of topological groups and modules is important in theory of topological groups, algebraic number theory. The tensor product of compact zero-dimensional modules over a pseudocompact algebra was introduced in [B] and for the commutative case in [GD], [L]. The notion of a tensor product of abelian groups was introduced in [H]. The tensor product of modules over commu...
The RB pathway is one of the best-studied and most frequently altered pathways leading to loss of proliferative control in cancer. it can be disrupted by a variety of means including, but not limited to, epigenetic silencing, allelic loss or mutation of RB1. in some cancers including breast cancer, amplification of the CCND1 gene or overexpression of cyclin D1 is commonly observed.1 in others, ...
