IDENTIFICATION OF TWO SUBSETS By EvERETT PITCHER
1. The Problem and the Motivation.-The theorems of this paper are motivated by the Mayer-Vietoris formulas,' which they include. Our form of statement is suggested by the exposition of Alexandroff and Hopf.2 In the simplest case, we have a complex K containing two subcomplexes C1 and C2, separated in K and each a copy of a complex C. Points of C1 and C2 corresponding to the same point of C are ...
متن کاملfunctional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner
نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...
Improved flow cytometric analysis of leukocyte subsets: simultaneous identification of five cell subsets using two-color immunofluorescence.
Flow cytometric analysis of human peripheral blood leukocytes has typically been achieved by staining multiple aliquots of the same sample with fluorescent reagents specific for cell subsets of interest. Spectrally discrete fluorochrome tags have been developed for applications in which identification of multiple subsets (e.g., T and B cells) or of subsets not uniquely identified by a single re...
متن کاملIdentification of polarized macrophage subsets in zebrafish
While the mammalian macrophage phenotypes have been intensively studied in vitro, the dynamic of their phenotypic polarization has never been investigated in live vertebrates. We used the zebrafish as a live model to identify and trail macrophage subtypes. We generated a transgenic line whose macrophages expressing tumour necrosis factor alpha (tnfa), a key feature of classically activated (M1)...
متن کاملDemonstration of Functional Heterogeneity of T lymphocytes and Identification of Their Two Major Subsets
Cells responsible for the specificity of the immune response and thymus function remained unknown until mid 1960s when lymphocytes were identified as mediators of cellular and humoral immunity (1–4). Soon afterward in vivo reconstitution experiments showed that cellular and humoral immunity are mediated by two different types of lymphocytes: thymusderived T cells and thymus-independent, bone ma...
