The aim of our present study was to determine the concentration of arsenic (As), copper (Cu), cobalt (Co) and manganese (Mn), in biological samples of male production workers (PW) and quality control workers (QW) of steel mill, with aged 25–55 years, to assess the possible influence of environmental exposure.

The Mixer Mill MM 400 can be used to easily homogenize the sputum sample; however, since 2 ml vials were used in the past, it was not feasible to process more than 1 ml of each sputum sample. It was not an appropriate procedure to divide the viscous and tough sputum into portions for homogenization as it is a partly infectious material.

The original lid of the laboratory freezer (1) was replaced by a top unit made out of thermally insulating material (2) which was covered by a detachable transparent Plexiglas ® pane (3). The …

Cryogenic mills use liquid nitrogen or other cryogenic gases to cool down the grinding chamber to ultra-low temperatures, typically below -150 °C. This extreme coldness helps in brittle and heat-sensitive materials, such as plastics, rubber, and biological samples, where maintaining sample integrity is crucial.

These mills often achieve finer grind sizes, even with difficult plastic samples, than for example rotor mills because the sample remains for a longer period inside the closed grinding jar compared to the open grinding chamber of the rotor mills. The sample is cooled continuously during the entire grinding process, in the CryoMill even with a ...

Mixer mills are frequently used for homogenizing biological samples. The so-called bead beating with small glass beads is an established method for cell disruption of yeasts, microalgae or bacteria. The sample is only …

Background. Evidence based methods in medicine and other health related fields have emphasized biological plausibility as an important element in assessing the strength of evidence since the work of Bradford Hill 1,2.As noted in a recent review of cancer risks, information on biological plausibility is particularly important as a complement to …

Background: To understand processes regulating nutrient homeostasis at the single-cell level there is a need for new methods that allow multi-element profiling of biological samples ultimately only available as isolated tissues or cells, typically in nanogram-sized samples. Apart from tissue isolation, the main challenges for such …

In life science research, biological samples are a critical resource, with many important uses. In this post, we will summarize the main types of biological …

Raman microspectroscopy is useful for the analysis of biological samples, because chemical and structural information can be obtained without using labels. This protocol brings together practical ...

All samples were negative for E. faecium after 48 h of heating. Both wet chemical cleaning and facility heating but not physical cleaning resulted in substantial E. faecium decontamination. These results confirmed both successful containment and decontamination of biological pathogens in the tested pilot-scale feed mill.

Product Description. MRC Labs SM series are high power laboratory sample mills with separate stainless steel grind container and high hardness steel blades, making it ideal for grinding tough, dry materials.

This review documents the overview of lipidomics workflow, beginning from the approaches of sample preparation, various analytical techniques and emphasizing …

Abstract. Abies alba Mill. (Pinaceae), silver fir, is a widespread gymnosperm species in Europe, important for its ecological, economic, social, and cultural significance, as well as for its use for food and bioremediation purposes. The various parts of the plant (leaves, branches, cones, wood, bark) are also of pharmaceutical interest due to ...

Cryo-fixation methods, such as high pressure freeze fixation (HPF) representing the state-of-the-art technique for best structural preservation, are not …

The complexities involved in proper sample management policies and procedures are often underestimated. Prior to initiating a study that will involve the collection of biological samples, many decisions need to be made that will affect the quality of the samples and the outcome of the study. The appropriate sample type(s) needs to be chosen.

Whatever sample type or throughput you work with, there is a QIAGEN sample homogenizer to meet your needs. We have a small footprint low-throughput rotor-stator homogenizer and low- to medium-throughput bead mill, as well as high-throughput bead mill with programmable protocols and custom program cycles.

Its flexibility (0.5, 2 and 7 ml tubes) and its small size make it ideal for laboratories needing conventional sample preparation. • The Precellys® 24 homogenizer can accommodate up to 24 biological samples in 2 ml and 0.5 ml tubes simultaneously. This robust appliance has been designed for daily use in laboratories with biological safety ...

The determination of toxic metals in the biological samples of human beings is an important clinical screening procedure. This study aimed to assess the possible influence of environmental exposure on production workers (PW) and quality control workers (QCW) of a steel mill, all male subjects aged 25-55 years.

Similarities with and between mills were derived from this dendrogram, i.e., the similarity value of the node where all samples from one mill converge and defines similarity within-mill. Similarity between 16S-RFLP profiles from mills was partially correlated to wood furnish (Baker et al . 2003).

Gaseous samples (Lawal et al. 2017) are rare and commonly sampled in environmental and classical analytical areas of research, but there are also some gaseous biological samples, like air (Mochalski et al. 2014) that is exhaled from the lungs, used in the bioanalytical field of research.Nitrogen, oxygen, carbon dioxide, argon, and water …

Interchangeable sample holders allow unique flexibility in terms of sample size (2 mL to 250 mL as well as 96 deep well plates) and temperature (ambient or cryogenic conditions).
