20090062203 | DIPEPTIDYL PEPTIDASE IV INHIBITORS FOR THE TREATMENT OF SCHIZOPHRENIA AND DEPRESSION - A method for therapeutically treating an animal, including a human, for psychosomatic, depressive and neuropsychiatric diseases, such as anxiety, depression, insomnia, schizophrenia, epilepsy, spasm and chronic pain. Administration of a suitable DP IV inhibitor causes the reduction of activity in the enzyme dipeptidyl peptidase (DP IV or CD 26) or of DP IV-like enzyme activity in the brain of mammals and leads as a causal consequence to a reduced degradation of the neuropeptide Y (NPY) and similar substrates by DP IV and DP IV-like enzymes. Such treatment will result in a reduction or delay in the decrease of the concentration of functionally active neuronal NPY (1-36). As a consequence of the resulting enhanced stability of the endogenous NPY (1-36) caused by the inhibition of DP IV activity, NPY activity is prolonged thereby resulting among other things in functionally active NPY Y1 receptor activity thereby facilitating antidepressive, anxiolytic, analgesic, antihypertension and other neurological effects. | 03-05-2009 |

20100266191 | METHOD FOR QUANTIFYING AN UNDERLYING PROPERTY OF A MULTITUDE OF SAMPLES - An approach for quantification of an underlying property of a multitude of samples, e.g. cellular biological samples, is described. In an exemplary application, input measures are mean pixel intensities from different segments of individual cells on original and filtered images. In another exemplary application, input measures are pixel intensities from different cells on a series of time-gated images. The set of input measures are expected to have a linear relationship to the underlying property. Latent variables are (1) a scalar noise factor responsible for intensity fluctuations in all segments of a cell at a time and (2) the main underlying property of the process responsible for observed changes on images. Linear coefficients for latent variables are determined using noise minimization while constraining the mean signal from positive and negative control samples to the corresponding theoretical values. The method is well suited for high throughput applications like drug screening. | 10-21-2010 |
20130064468 | Methods and Apparatus for Image Analysis and Modification Using Fast Sliding Parabola Erosian - Methods and apparatus are provided for image analysis and modification using a fast sliding parabola erosion. The methods include selecting a scan line in an image and performing a unidirectional left-hand pass followed by a unidirectional right-hand pass. The unidirectional passes are performed as loops with increasing distance. By utilizing simple unidirectional left-hand and right-hand passes along a scan line in an image, the erosion procedure is greatly simplified and computation times are significantly reduced. | 03-14-2013 |

20130064441 | Methods and Apparatus for Fast Identification of Relevant Features for Classification or Regression - In various embodiments, methods and apparatus are provided for automated selection of features of cells useful for classifying cell phenotype. The methods include determining a signal-to-noise ratio (S/N) for each of a plurality of pairs of features, rather than S/N for individual features. The approach is capable of quickly identifying a small set of features of imaged cells that are most relevant for classification of a desired cell phenotype from among a very large number of features. The small group of relevant features can then be used to more efficiently and more accurately classify phenotype of unidentified cells. | 03-14-2013 |
20130114874 | Methods and Apparatus for Image Analysis Using Threshold Compactness Features - A new family of morphological features, referred to herein as threshold compactness features, is provided, useful for automated classification of objects, such as cells, in images. In one embodiment, one or more thresholds and/or binary masks are applied to an image, and one or more provisional objects within a cell in the image are automatically identified. The threshold compactness of the cell is computed as a function of area S of the one or more provisional objects and border length P of the one or more provisional objects. Computation of threshold compactness allows cells in an image to be distinguished and characterized. Compared to previous techniques, the methods and apparatus described herein are more robust and computationally efficient. | 05-09-2013 |

In certain embodiments, the profile weighted intensity feature is determined by automatically identifying a border of a cell in an input image, determining a distance image for the cell, computing a profile function for the cell, and computing a mean intensity of at least a portion of the input image weighted by the profile function for the cell. | 05-09-2013 |
