Sampling Site Matters When Counting Lymphocyte Subpopulations

Sampling Site Matters When Counting Lymphocyte Subpopulations

Clinical and scientific work routinely relies on antecubital venipunctures for hematological, immunological or other analyses on blood. This study tested the hypothesis that antecubital veins can be considered to be a good proxy for other sampling sites. Using a hematocytometer and a flow cytometer, we analyzed the cell counts from samples coming from the radial artery, the dorsal hand veins an...

ALTERATION OF T-LYMPHOCYTE SUBPOPULATIONS IN SUBACUTE AND CHRONIC BRUCELLOSIS

Human brucellosis is a major health problem in developing countries. A number of patients with human brucellosis do not recover from the acute stage of the disease and pass into the chronic form. Since the pathophysiology of this change is not well understood, we studied the T-cell subsets during the acute, subacute and chronic forms of human brucellosis. In this study we found alterations...

Heterogeneity of Lymphocyte Subpopulations

or very minimal in all three, including cell-mediated responses in vivo; the in vitro proliferative response to mitogens, allogeneic cells, or antigens; effector cell function in lymphocyte-antibody lymphocytolytic interaction assays; and in vitro synthesis of IgG, IgA, and IgM. In contrast, mononuclear cells from one of the infants were tested and found capable of lysing both human and chicken...

[Cardiac resynchronization therapy: when the pacing site really matters].

Cardiac resynchronization therapy has been one of the major qualitative advances made in the treatment of heart failure in recent decades, and it strongly underlines the relationship between heart mechanics, hemodynamic function, and electrophysiology. Since the 1980s a number of clinical and experimental studies have shown that abnormalities in intraventricular conduction, associated or not wi...
