Serum cholesterol is measured to determine the concentration of circulating lipoprotein particles when screening for cardiovascular disease. The concentration is affected by genetic and lifestyle factors. Cholesterol concentrations in serous effusions increase due to exudative processes that cause cell lysis or increased vascular permeability. Measurement of cholesterol in body fluids is used for the diagnosis of a cholesterol effusion or cholesterol-rich pseudochylous effusion. Pseudochylous effusions contain low triglycerides and high cholesterol and occur from chronic pleural effusions such as rheumatic pleurisy and tuberculosis. Malignant effusions may become enriched with cholesterol due to increased synthesis and release from neoplastic cells or lymphatic obstruction.

Pleural fluid:

Chylothorax is the name given to pleural effusions containing chylomicrons with accordingly high triglyceride and low cholesterol concentrations, which occurs when chyle accumulates from a disruption of the thoracic duct caused mainly by malignancy or trauma.

Pseudochylous effusions accumulate gradually through the breakdown of cellular lipids in long-standing effusions such as rheumatoid pleuritis, tuberculosis, or myxedema, and by definition, the effluent contains high concentrations of cholesterol, while chylous effusions contain high concentrations of triglycerides in the form of chylomicrons.

Differentiation of pseudochylothorax from chylothorax is important as their milky or opalescent appearance is similar; however, therapeutic management strategies differ.

These recently developed ultra-stable gold supports for electron cryomicroscopy reduce the movement of frozen specimens during imaging. This improves image contrast and quality leading to better 3D reconstruction in TEM tomography applications.

During imaging at cryo-temperatures, traditional carbon supports move, particularly at the beginning of irradiation. This movement blurs images and makes it difficult to determine the structures of small and challenging molecules

Characteristics of UltrAuFoil

• Thickness of gold foil: approx 500
• Structure of gold foil: regular square array of micrometer-sized circular holes
• Geometry: R1.2/1.3 R0.6/1 and R2/2
• Gold 300 mesh (R0.6/1 or R1.2/1.3 geometry)
• Gold 200 mesh (R2/2 geometry)
• Other types are also available

Using UltrAuFoils, designed at MRC's Laboratory of Molecular Biology by DrChristopherJRusso and DrLoriAPassmore and produced by Quantifoil Micro Tools, specimen motion can be reduced significantly

Lacey carbon films are similar to the holey carbon films in that they have open areas but because of the fine lacey mesh structure they offer a greater percentage of open area in comparison (see micrograph). They provide the thinnest possible support film while maintaining adequate strength and give practically no background interference in the TEM. As much of the specimen is unsupported, these films are appropriate for use where a structure free background is of importance. Lacey carbon films are particularly suitable for studying some nanotubes, acicular crystals and biological/materials specimens.

Supplied as 25 or 50 grids in a grid box.

Lacey carbon support films can be applied to other grid sizes, material or type. Further details available on request.

Holey carbon films have many uses in microscopy but for certain applications the mesh sizes of standard TEM grids are too large to support the sample. Continuous carbon films can also be a problem due to the fact that the thin film can inelastically scatter electrons and contribute to background noise. Holey carbon films therefore are a suitable alternative.
Holey carbon films have holes of various sizes up to 100m. In addition to providing support, the increased image contrast in the regions of the holes compared to regions of film is also of benefit. Typical applications include biological and materials science and cryo-TEM.

Holey carbon support films can be applied to other grid sizes, material or type. Further details available on request.
