Background. While the mitral annular plane systolic excursion (MAPSE) has been suggested as a surrogate measurement of left ventricular ejection fraction, less is known about the relative value of mitral annular ascent (MAa). Methods. Our database was queried for complete transthoracic echocardiograms performed for any clinical indication. Baseline echocardiographic measurements were compared t...
This prospective cohort study evaluated the use of videofluoroscopy in assessing changes in both antero-posterior (A-P) and transverse pharyngeal airway dimensions in patients with obstructive sleep apnoea (OSA). Forty patients [32 males and 8 females; mean age of 49.3 (SD = 10.79) years] with confirmed OSA, referred for mandibular advancement appliance (MAA) therapy were recruited. Patients re...
In six sheep, radiopaque markers were placed on the left ventricle (LV), the mitral annulus, the left atrium (LA), and the central edge of both mitral leaflets to investigate the effects of acute LV ischemia on atrial contraction, mitral annular area (MAA), and mitral regurgitation (MR). Animals were studied with biplane videofluoroscopy and transesophageal echocardiography before and during ba...
Several studies have reported the occurrence and significance of programmed cell death (apoptosis) of testicular germ cells in mammals. In those studies, apoptotic germ cells were identified by morphological criteria or by in situ end labeling (TUNEL) and were enumerated from histological sections by semi-quantitative and time-consuming techniques. In the present study, we have established a fl...
Human melanoma cells freshly isolated from 20 patients with primary and 73 patients with metastatic melanomas were analyzed by indirect immunofluorescence staining with monoclonal antibodies (MoAb) to class I (HLA-A, -B, and -C) and class II (HLA-DR and -DQ) antigens and to melanoma associated antigen (MAA). The latter included the GD3-MAA and the high molecular weight MAA. HLA class I antigens...
The gene that encodes the membrane-bound M, 100,000 human mel anoma-associated antigen (M VV) defined by mouse mAb 376.96, a leukocyte and fibroblast interferon-modulated glycoprotein having pref erential distribution on melanoma and carcinoma cells, has been transfected into the mouse melanoma cell line B78H1 as a step toward molecular cloning and characterization of the MAA. Primary, secondar...
Seven amphiphilic conetworks of methacrylic acid (MAA) and a new hydrophobic monomer, 2-butyl-1-octyl-methacrylate (BOMA), were synthesized using group transfer polymerization. The MAA units were introduced via the polymerization of tetrahydropyranyl methacrylate (THPMA) followed by the removal of the protecting tetrahydropyranyl group by acid hydrolysis after network formation. Both THPMA and ...
To overcome unresponsiveness to the self-high molecular weight melanoma-associated antigen (HMW-MAA) in hosts with constitutive HMW-MAA expression, we have used as immunogen the anti-idiotypic monoclonal antibody (mAb) MK2-23, which mimics the antigenic determinant recognized by the anti-HMW-MAA mAb 763.74. In a phase I/II clinical trial, anti-idiotypic mAb MK2-23, conjugated to keyhole limpet ...
BACKGROUND SIRT is an emerging treatment for liver tumours which relies on the selective uptake by tumour of 90Y microspheres following hepatic arterial injection. Response rates of around 90% are reported. Hepatic arterial injection of MAA gives an indication of the expected distribution of 90Y microspheres within the liver. This study sought to determine if the MAA scan could be predictive of...
The aim of this randomized controlled trial was to assess the effectiveness of a mandibular advancement appliance (MAA) in managing severe snoring. Twenty-eight adults with severe snoring and normal overnight oximetry were recruited from sleep disorder clinics. A maxillary placebo appliance and a MAA were worn by each subject for a period of 4-6 weeks each. Questionnaires at baseline and after ...
