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; ...

BACKGROUND AND PURPOSE The presence of IPH and/or FCR in the carotid atherosclerotic plaque indicates a high-risk lesion. The aim of this multicenter cross-sectional study was to establish the characteristics of lesions that may precede IPH and/or FCR. We further sought to construct a CAS that stratifies carotid disease severity. MATERIALS AND METHODS Three hundred forty-four individuals from...
