چکیده

Visual inspection of cells is a fundamental tool for discovery in biological science. Modern robotic microscopes are able to capture thousands of images from massively parallel experiments such as RNA interference (RNAi) or small-molecule screens. Such screens also benefit from lab automation, making large screens, e.g., genome-scale knockdown experiments, more feasible and common. As such, the bottleneck in large, imagebased screens has shifted to visual inspection and scoring by experts. In this paper, we describe the methods we have developed for automatic image cytometry. The paper demonstrates illumination normalization, foreground/background separation, cell segmentation, and shows the benefits of using a large number of individual cell measurements when exploring data from highthroughput screens.

Increasing the Content of High-Content Screening

Target-based high-throughput screening (HTS) has recently been critiqued for its relatively poor yield compared to phenotypic screening approaches. One type of phenotypic screening, image-based high-content screening (HCS), has been seen as particularly promising. In this article, we assess whether HCS is as high content as it can be. We analyze HCS publications and find that although the numbe...

Phenotypic distance measures for image-based high-throughput screening

High-throughput image-based screening (also termed high-content screening) has become a popular method in systems biology, functional genomics and drug discovery. Data analysis of high-content screening can be divided into two steps: image quantification and phenotypic analysis. Previously we have developed two R packages, EBImage and imageHTS for image quantification. The current R package phe...

I-1: Screening of Subfertile Men for Testicularlar Carcinoma In Situ by An Automated Image Analysis-Based Cytological Test of The Ejaculate

Background: Testicular cancer (TC) is usually diagnosed after manifestation of an overt tumour. Tumour formation is preceded by a pre-invasive and asymptomatic stage, carcinoma in situ (CIS) testis, except for very rare subtypes. The CIS cells are located within seminiferous tubules but can be exfoliated and detected in ejaculates with specific CIS markers. Materials and Methods: We have built ...

Nootropic Medicinal Plants; Evaluating Potent Formulation By Novelestic High throughput Pharmacological Screening (HTPS) Method

The principle of this method was to screen the pharmacological activity of six prepared polyphyto formulations by using high throughput screening method for their nootropic action. The study was performed in three stages using one, two and three animals, respectively in a group. Test formulations were given p.o daily at the dose of 50 and 100 mg/kg body weight. The test formulations were compar...
