CONTEXT Low plasma high-density lipoprotein (HDL) cholesterol is a major abnormality in abdominal obesity. This relates due to accelerated HDL catabolism, but the underlying mechanism requires further elucidation. The relationships between HDL catabolism and other variables that may be modified in abdominal obesity, such as very low-density lipoprotein (VLDL) subspecies (VLDL1, VLDL2) kinetics,...

Receptors for the Fc portion of Ig (Fc receptors, FcR) are found on all cell types of the immune system. Three types of FcR react with IgG: Fc gamma RI is a high-affinity receptor binding IgG monomers whereas Fc gamma RII and Fc gamma RIII are low-affinity receptors binding IgG immune complexes; the three types of Fc gamma R are members of the Ig superfamily. Two FcR react with IgE:Fc epsilon R...

Receptors for the Fc domain of IgG (FcR)' are present on the membranes of cells of the myeloid and monocytic lineages (1) as well as on other unrelated cell types (2-4). Myelomonocytic cells interact with IgG antibody-sensitized cells or pathogenic organisms through their FcR: this interaction results in the activation of cellular defense mechanisms, such as antibody-dependent cell-mediated cyt...

PURPOSE The purpose of this study was to understand the detailed architectural properties of the human flexor carpi radialis (FCR) and flexor carpi ulnaris (FCU) muscles and their implications for tendon transfer surgery. METHODS Muscle fiber length was measured in 6 separate regions of the FCU and FCR from 10 cadaveric specimens. Sarcomere length was measured by laser diffraction for normali...

Phagocytosis by macrophages can be initiated by Fcgamma receptors (FcR) in membranes that bind to Fc regions of immunoglobulin G (IgG). Activated FcR transduce signals to cytoplasm, which regulate the internalization of IgG-coated particles into plasma membrane-derived vacuoles, phagosomes. Particles internalized by phagocytosis are much larger than FcR, which prompts questions of if and how th...

Interferon (IFN)-induced modulation of two distinct types of Fc receptors (FcR) on bovine bone marrow culture-derived macrophages was quantified by flow cytometry. We have established the presence of separate FcR for monomeric and aggregated IgG on these cells, equivalent to the FcRI and FcRII of mice, respectively. These two kinds of FcR differed in protease sensitivity, hierarchy of preferent...

While previous studies have assessed changes in corticospinal excitability following voluntary contraction coupled with electrical stimulation (ES), we sought to examine, for the first time in the field, real-time changes in corticospinal excitability. We monitored motor evoked potentials (MEPs) elicited by transcranial magnetic stimulation and recorded the MEPs using a mechanomyogram, which is...

Background Fear of cancer progression/recurrence (FOP/FCR) is considered one of the most prevalent sources of distress in cancer survivors and associated with lower quality of life and functional impairment. Detailed measures of FOP/FCR are needed because little is known about the knowledge of FOP/FCR, its associations with the patient-doctor relationship, and the rate of adequate therapy. Colo...

The Forced Choice Recognition (FCR) and the Critical Item Analysis (CIA) indices of the California Verbal Learning Test-II (CVLT-II) have been identified by the CVLT-II test developers as potentially useful, brief screening indicators of effort in neuropsychological assessment. This retrospective study analyzes performance on these measures in three groups: (1) clinically referred individuals; ...
