Brain Tumor Detection by Using Stacked Autoencoders in Deep Learning.

J Med Syst 2019 Dec 17;44(2):32. Epub 2019 Dec 17.

Division of Computer Science, Mathematics and Science, Collins College of Professional Studies, St. John's University, New York, USA.

Brain tumor detection depicts a tough job because of its shape, size and appearance variations. In this manuscript, a deep learning model is deployed to predict input slices as a tumor (unhealthy)/non-tumor (healthy). This manuscript employs a high pass filter image to prominent the inhomogeneities field effect of the MR slices and fused with the input slices. Read More

Hacettepe cartilage slicer: a novel cartilage slicer and its performance test results.

J Laryngol Otol 2017 Aug 27;131(8):671-675. Epub 2017 Apr 27.

Department of Otorhinolarynogology Head and Neck Surgery,Hacettepe University Faculty of Medicine,Ankara,Turkey.

Objective: This study investigated the performance of a cartilage slicer device referred to as the 'Hacettepe cartilage slicer'.

Methods: Forty-one cartilage pieces were harvested from eight fresh frozen human ears and measured in thickness with a digital micrometer. These pieces were randomly sliced using four different thickness settings and two different types of blades. Read More

An automated framework for NMR resonance assignment through simultaneous slice picking and spin system forming.

J Biomol NMR 2014 Jun 19;59(2):75-86. Epub 2014 Apr 19.

Computer, Electrical and Mathematical Sciences and Engineering Division, King Abdullah University of Science and Technology (KAUST), Thuwal, 23955-6900, Saudi Arabia.

Despite significant advances in automated nuclear magnetic resonance-based protein structure determination, the high numbers of false positives and false negatives among the peaks selected by fully automated methods remain a problem. These false positives and negatives impair the performance of resonance assignment methods. One of the main reasons for this problem is that the computational research community often considers peak picking and resonance assignment to be two separate problems, whereas spectroscopists use expert knowledge to pick peaks and assign their resonances at the same time.

The Bionas technology for anticancer drug screening.

Expert Opin Drug Discov 2009 Jul 8;4(7):785-97. Epub 2009 Jun 8.

University "Rey Juan Carlos" (URJC), Department of Health Sciences I, Laboratory of Histology and Cell Biology, Faculty of Health Sciences, Avda. de Atenas s/n, E-28922 Alcorcón, Madrid, Spain +34 91 4888640 ; +34 91 4888955 ;

Background: The Bionas 2500(®) analyzing system is an advanced label-free technology using a cell-based multi-sensor array, which is commercially available. Data on metabolism, respiration, adhesion, cell proliferation and cell death rates, as well as ligand-receptor interactions (multi-parametric) can be acquired and statistically evaluated. Noteworthy is the possibility of analyzing later after effects and/or recovery after drug treatment. Read More

Rapid quantification of left ventricular function and mass using transoesophageal three-dimensional echocardiography: validation of a method that uses long-axis cutplanes.

Eur J Echocardiogr 2000 Sep;1(3):213-21

Medical Clinic I, University Hospital, Aachen, Germany.

Aims: Despite its proven superiority compared to conventional echocardiographic techniques, three-dimensional (3D) echocardiography has not gained widespread acceptance in clinical medicine for the quantification of left ventricular volumes, function and mass. This is mainly due to the large, time-consuming process of data analysis. We sought to validate a new method that enables the accurate quantification of the left ventricle in a clinically acceptable short period of time. Read More

Time window control: a model for cerebellar function based on synchronization, reverberation, and time slicing.

Prog Brain Res 2000 ;124:275-97

Center for Neuromimetic Systems, Swiss Federal Institute of Technology, Lausanne EPFL, Switzerland.

We present a new hypothesis of cerebellar function that is based on synchronization, delayed reverberation, and time windows for triggering spikes. Our model suggests that granule cells admit mossy fiber activity to the parallel fibers only if the Golgi cells are firing synchronously and if the mossy-fiber spikes arrive within short and well-defined time windows. The concept of time window control organizes neuronal activity in discrete 'time slices' that can be used to discern meaningful information from background noise. Read More

Microcomputer-aided reconstruction: a system designed for the study of 3-D microstructure in histology and histopathology.

J Microsc 1987 Apr;146(Pt 1):55-65

We have designed a microcomputer system to reproduce 3-D tissue structures graphically from serial microscopic sections. The system, based on a Hewlett-Packard model 310 desktop computer, comprises a floppy disc drive, a hard-disc that extends the available user memory by adding 40 Mbytes, a colour memory-mapped graphics display, a graphics tablet and a graphics printer. A set of serial 2-D images, manually extracted from serial sections using a microprojector, are digitized on the tablet by tracing the contours of the structure of interest; up to ten different structures can be inputted and reproduced using a 'hidden line' effect.
