Measurement of the Osmolarity of Salt Solutions Using Semi-Micro Osmometer

One of the most common medical problems in the area of ophthalmology is dry eye syndrome. The eyes usually become dry as a result of external influences such as air travel, air pollution, air conditioning and central heating. This often leads to the tear fluid losing liquid and becoming more concentrated. This article describes a simple and fast technique that can be used to ascertain the osmolarity of salt solutions for the preparation of eye drops.

Automated Fluorescence Cell Counters for Cell Counting and Viability Analysis

From the late 1990s, a range of image-based automated cell counters have been launched that provide precise data on cell number and viability. These counters essentially use a combination of image analysis software and light microscopy. A digital camera captures magnified cell images and software algorithms are used to precisely detect cells and distinguish them from non-cellular objects such as cell debris.

Chromatrap Immunoprecipitation Assay Enriches Epigenetic Histone Methylation Marks from Primary Biopsy Samples

The uterus is a pear-shaped organ that consists of a lower barrel shaped cervix and a large upper body with the 'fundus' over the uterine tubes. It has a thick muscular wall, which houses the human fetus from conception to birth.

Chromatrap® Technology for Studying Complex Epigenetic Mechanisms

Chromatin immunoprecipitation (ChIP) is a widely used technique for mapping the interactions between intracellular proteins and their DNA targets in gene regulation. The epigenetic mechanisms that affect chromatin formation and control the availability of the DNA backbone to transcription factor regulators is an important area of research. ChIP is a technology that allows researchers a glimpse into the regulatory mechanisms that gene expression.

Setting Effective Product Specifications in Pharmaceutical Manufacturing

An important aspect of Quality by Design (QbD) is to establish meaningful and realistic specifications. Well-defined specifications control the performance of products, as they derive from associations between clinical behaviour and the variables determined routinely during processing for quality control. This article investigates the process of setting specifications, taking particle size as an example which is a major parameter for a variety of pharmaceutical formulations.

Darkfield Hyperspectral Imaging for Analysis of Nanoparticles in Cancer Cells

Biological samples typically contain nanomaterials that scatter light significantly, and these samples are usually studied with dark field illumination. When dark field illumination is combined with hyperspectral imaging, it becomes a unique tool that can be used for identifying the location and composition of nanomaterials embedded in cells. To this end, the IMA hyperspectral imager supplied by Photon etc can be used for this application. A high-efficient dark field condenser can be fitted to this hyperspectral imager to produce high contrast images of biological samples.

Application of Cryogenically Cooled Resonators for High-Resolution Brain Imaging and Functional Cardiac Imaging

Magnetic resonance imaging (MRI) is usually restricted by the resulting signal-to-noise ratio (SNR). Use of higher field strength and improvement in the radiofrequency (RF) receive coil design are believed to facilitate significantly higher SNR.
