Clustered Microcalcification Detection Using Optimized Difference Of Gaussians, Edward M. Ochoa
Clustered Microcalcification Detection Using Optimized Difference Of Gaussians, Edward M. Ochoa
Theses and Dissertations
The objective of this thesis is to design an automated microcalcification detection system to be used as an aid in radiologic mammogram interpretation. This research proposes the following methodology for clustered microcalcification detection. First, preprocess the digitized film mammogram to reduce digitization noise. Second, spatially filter the image with a difference of Gaussians (DoG) kernel. To detect potential microcalcifications, segment the filtered image using global and local thresholding. Next, cluster and index these detections into regions of interest (ROIs). Identify ROIs on the digitized image (or hardcopy printout) for final radiologic diagnosis.

Experience With Larangeal Mask Airway In Pakistani Patients, F A. Khan, M A. Afzal, R S. Kamal
Department of Anaesthesia
One hundred and thirty seven adult patients undergoing peripheral surgery were studied regarding ease of larangeal mask airway (LMA) insertion, airway maintenance during surgery and complication encountered during insertion, maintenance and in the postoperative period. In a majority (84%) of patients, the airway was positioned correctly at the first attempt, 3% patients had mild laryngospasm at insertion and in 85% a good airway was obtained. No airway related problems were encountered intraoperatively. Two percent patients had laryngospasm on removal of LMA. Postoperatively, the complaint of sore throat and uvular trauma was seen in 4% cases.

An Animal Model For Development Of Pulpal Inflammation, John W. Masters
Loma Linda University Electronic Theses, Dissertations & Projects
Several animal models have been proposed to develop pulpal inflammation. Procedures recommended in these models have many variables and have not produced consistent results. The purpose of this study was to create pulpal inflammation using the Nd:YAG laser.
Forty-five cuspids of 12-18 month old beagle dogs were lased at 5, 7.5, and 10 watts (W) for 20 seconds with a 600 micron contact probe. Five cuspids were not lased but were used as controls. Following laser application, the teeth were extracted at intervals of 3, 7, and 30 days. They were then fixed in 10% formalin, decalcified, sectioned, and stained …

Mutagenecity Of Formocresol, Glutaraldehyde, Ferric Sulfate And Aluminum Chloride : Materials Used In Therapeutic Pulpotomies, Adolfo Barrera
Loma Linda University Electronic Theses, Dissertations & Projects
Ferric sulfate (Astringedent) and aluminum chloride (Hemodent) have been proposed as possible medicaments for use in primary teeth for therapeutic pulpotomies.
There is little information in the literature about the biologic properties of these medicaments.
The purpose of this study was to evaluate the mutagenic response of the ferric sulfate and aluminum chloride and compare them with glutaraldehyde (1.5%, 1% and 0.5% concentration) and formocresol (2%, 0.75%, 0.01% and 0.005% concentration). TA98 and TA1535 strain were used in the Ames test to assess mutagenecity. Neither ferric sulfate nor aluminum chloride exhibited mutagenic potential, in comparison with glutaraldehyde and formocresol, which …

Purple membrane (PM, λ" role="presentation">λmax" role="presentation">max 570 nm) of H. halobium on treatment with sulphuric acid changes its colour to blue (λ" role="presentation">λmax" role="presentation">max 608 nm). The purple chromophore can be regenerated from the blue chromophore by exogeneous addition of anions such as CI−" role="presentation">− and HPO42−" role="presentation">2−4. Chloride ion is found to be more effective than the dibasic phosphate ion in regenerating the purple chromophore. Nevertheless, one thing common to the anion regeneration is that both CI−" role="presentation">− and HPO42−" role="presentation">2−4 show marked pH effect. At pH 1.0 the efficiency of …

The following results were found: 1) Average treatment time was 9 months. 2) An overcorrected Class I relationship was achieved. 3) Class II malocclusion was corrected by 4.5 mm skeletal alteration …
Ultrasound Three- Dimensional Velocity Measurements By Feature Tracking, Gregory R. Bashford, Olaf T. Von Ramm
Ultrasound Three- Dimensional Velocity Measurements By Feature Tracking, Gregory R. Bashford, Olaf T. Von Ramm
Biomedical Imaging and Biosignal Analysis Laboratory
This article describes a new angle-independent method suitable for three-dimensional (3-D) blood flow velocity measurement that tracks features of the ultrasonic speckle produced by a pulse echo system. In this method, a feature is identified and followed over time to detect motion. Other blood flow velocity measurement methods typically estimate velocity using one- (1-D) or two-dimensional (2-D) spatial and time information. Speckle decorrelation due to motion in the elevation dimension may hinder this estimate of the true 3-D blood flow velocity vector. Feature tracking is a 3-D method with the ability to measure the true blood velocity vector rather than …

Job Accommodation In The Automobile Industry : Addressing The Problem Of Lateral Epicondylitis, Thanigaivel Ashwin Raj
Theses and Dissertations (ETD)
Cumulative trauma disorders are musculoskeletal problems such as carpal tunnel syndrome, rotator cuff tendinitis, and epicondylitis which can affect assembly line workers. The injuries are thought to result from repetitive motions performed under excessive loads in anomalous postures. The project aimed to design, build, install, and evaluate worksite accommodation at the Saturn plant for a worker with right lateral epicondylitis. The goal was to make her fully functional in her original team which required addressing the injurious aspects of the task that caused or aggravated her injury.
A process of observation, interview, and analysis identified “the door mount” operation on …

Publications from Provost Junius J. Gonzales
Outpatient consultation-liaison (C-L) psychiatry clinics are valuable settings for research and teaching endeavors. However, little is known about psychiatric symptoms and health status of persons treated in such settings. In this study, 80 persons seen in an outpatient C-L psychiatry clinic were compared with 100 persons seen in a mood disorder clinic on a variety of self-report instruments. Outpatient C-L clinic patients were found to have significantly poorer health status than mood clinic patients on the following domains as measured by the RAND instrument: general health perception, pain, physical functioning, and role functioning due to physical problems. Both groups had …

New rapid human immunodeficiency virus (HIV) antibody tests permit many individuals to receive test results and appropriate counseling at one clinic visit. Because currently used tests require significant time for processing, all individuals must return for a second visit for test results and counseling. Since return rates for the second visit are low, the more rapid tests present an opportunity to improve the efficiency of HIV counseling and testing.
The authors compared the costs and effectiveness of the currently used counseling and testing procedure and a streamlined procedure made possible by the new, more rapid screening tests. When test-positive clients …

In the United States, nearly all new human immunodeficiency virus (HIV) infections in children are acquired through perinatal (mother-to-infant) transmission. Each year, approximately 7000 infants are born to HIV-infected women in the United States.1 Without intervention, an estimated 15-30% of these infants would become infected.2 In 1994, results of the AIDS Clinical Trial Group (ACTG) Protocol 076 showed that treatment of infected pregnant women and their infants with zidovudine (ZDV) reduced the rate of perinatal HIV transmission from 25% to 8%.3,4 Following these findings, the Public Health Service (PHS) issued recommendations for ZDV therapy to prevent perinatal …
