The various forms of psoriasis demonstrate multidirectional changes of the expression of markers of lymphocyte positive and negative activation. Study of activation markers allow identifying different lymphocyte subpopulations, establishing their role in development and progressing of psoriasis as they characterize connected with cellular cycle processes of activation (CD25) and apoptosis (CD95...

In this paper, the new concept of near PS-compactness in L-topological spaces is introduced. It is defined for any L-subset. Its characterizations and topological properties are systematically studied. And the relationship is exposed between near PScompactness and PS-compactness, and also fuzzy compactness. 2003 Elsevier Inc. All rights reserved.

Let A be a nite set of integers. For h 1, let S h (A) denote the set of all sums of h distinct elements of A. Let S(A) denote the set of all nonempty sums of distinct elements of A. The direct problem for subset sums is to nd lower bounds for jS h (A)j and jS(A)j in terms of jAj. The inverse problem for subset sums is to determine the structure of the extremal sets A of integers for which jS h ...

We investigated the roles of microtubule (MT) dynamics (growth and shrinkage), the stable, nongrowing MT subset, the posttranslationally detyrosinated MT subset, and artificially elevated tubulin levels in the negative regulation of heart cell beating rate. We manipulated the MT populations in isolated, neonatal cardiomyocytes obtained from normal animals in several ways and then measured heart...

transient hypogammaglobulinemia (thi) of infancy is a common primary immunodeficiency usually resolves by 3 years of age. in this study, clinical, immunological data and outcome of 101 retrospectively diagnosed thi patients were evaluated. majority of them suffered from recurrent respiratory infections (70.3%). initial igg, igm and iga levels were 446.7±121.5, 67.5±32.8, and 25.6±16.8 mg/dl, re...

This paper focuses on the relationship between an $L$-subset and the system of level-elements induced by it, where the underlying lattice $L$ is a complete residuated lattice and the domain set of $L$-subset is an $L$-partially ordered set $(X,P)$. Firstly, we obtain the sufficient and necessary condition that an $L$-subset is represented by its system of level-elements. Then, a new representat...

Although the relative contribution of different immune effector functions to clearing tissues of cytomegalovirus is controversial, the contribution of CD8+ T lymphocytes has generally been accepted as essential. In this report, we show that under certain conditions the CD8+ T-lymphocyte subset can be dispensable for clearance of cytomegalovirus. Mice depleted of the CD8+ T-lymphocyte subset eli...
