The binding of [(3)H]?-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) to synaptic membranes of rat brain was characterized in the absence of detergents and chaotropes. Optimal conditions for binding were a centrifugation assay employing a well washed, frozen-thawed synaptic membrane preparation and a 40 min incubation at 4 degrees C in 50 mM(More)
The stretching capability of the zonules was studied in 40 human eyes obtained postmortem from 27 patients. A continuous circular capsulorhexis (CCC) (2.2-6.8 mm) was performed, and the lenses were removed by either phacoemulsification (26 eyes) or planned extracapsular cataract extraction (ECCE) (14 eyes). Maximal zonular stretch was calculated as the(More)
The objective of this study was to characterize the concentrations of lead, mercury, cadmium, aluminum, and manganese in umbilical cord blood of Jamaican newborns and to explore the possible association between concentrations of these elements and certain birth outcomes. Based on data from 100 pregnant mothers and their 100 newborns who were enrolled from(More)
OBJECTIVES Initial review of patients undergoing screening mammography imaged with a combination of digital breast tomosynthesis (DBT) plus full field digital mammography (FFDM) compared with FFDM alone. MATERIALS AND METHODS From June 2011 to December 2011, all patients presenting for routine screening mammography were offered a combination DBT plus FFDM(More)
PURPOSE A retrospective evaluation of the ability of computer-aided detection (CAD) ability to identify breast carcinoma in standard mammographic projections. MATERIALS AND METHODS Forty-five biopsy proven lesions in 44 patients imaged digitally with CAD applied at examination were reviewed. Forty-four screening BIRADS category 1 digital mammography(More)
To date much of the biomonitoring related to exposure to polychlorinated biphenyls (PCBs) and organochlorine (OC) pesticides is from middle to high income countries, including the U.S., Canada and Europe, but such data are lacking for the majority of low to middle income countries. Using data from 64 pregnant mothers who were enrolled in 2011, we aimed to(More)
All solvents (methanol, diethyl ether, n-hexane, water, benzene and iso-octane) were of pesticide grade (J.). Anhydrous sodium sulfate was solvent-rinsed and heated at 130 °C for at least 24 h prior to use (J.T. Baker, Center Valley, PA, USA); Florisil ® was also heated at 130 °C for at least 24 h prior to use (EMD, Gibbstown, NJ, USA). A three percent (3%)(More)
OBJECTIVE To demonstrate the importance of presurgical bilateral breast Magnetic Resonance Imaging (MRI) in women 60 years of age and older. MATERIALS AND METHODS Institutional review board approval was obtained with waiver of informed consent for this retrospective review. From December 2003 to December 2011, all patients 60 years and older who had(More)
OBJECTIVES To compare the visualization and image quality of microcalcifications imaged with digital breast tomosynthesis (DBT) versus conventional digital mammography. MATERIALS AND METHODS Patients with microcalcifications detected on full field digital mammography (FFDM) recommended for needle core biopsy were enrolled in the study after obtaining(More)
OBJECTIVE The aim of this study was to evaluate the effectiveness of computer-aided detection (CAD) to mark the cancer on digital mammograms at the time of breast cancer diagnosis and also review retrospectively whether CAD marked the cancer if visible on any available prior mammograms, thus potentially identifying breast cancer at an earlier stage. We(More)
