Mechanisms and functions of ribosome-associated protein quality control

open access: yesNature Reviews Molecular Cell Biology, 2019
The stalling of ribosomes during protein synthesis results in the production of truncated polypeptides that can have deleterious effects on cells and therefore must be eliminated.

Quality Control for Hematology

Postgraduate Medicine, 1968
To control quality of hematology tests, technologists should calibrate each piece of glassware, recheck instrument calibrations often, test series of samples in duplicate, correlate related tests such as hemoglobins and red blood cell counts with mean corpuscular hemoglobins or mean corpuscular hemoglobin concentrations, and refer questionable ...

Quality Control in Pediatrics

Archives of Pediatrics & Adolescent Medicine, 1981
The origin, growth, and development of the American Board of Pediatrics throughout 45 years is traced. The principles that have guided and the problems overcome in the establishment of an acceptable mechanism for primary certification are discussed. Relevance to the process of developing a mechanism for recertification is suggested.

Instrument Quality Control

2016
Well-defined quality control (QC) processes are used to determine whether a certain procedure or action conforms to a widely accepted standard and/or set of guidelines, and are important components of any laboratory quality assurance program (Popa-Burke et al., J Biomol Screen 14: 1017-1030, 2009).

Water Quality Control

2008
The aim of WQC is to establish whether or not a certain water body is in undisturbed conditions and, if this is not the case, which is the level of disturbance and wheter or not its quality is compatible with its intended uses.

Radiopharmaceutical quality control

Seminars in Nuclear Medicine, 1974
Kits are currently available for the preparation of technetium-labeled compounds for scanning the lungs, liver, kidneys, and skeleton. Prior to administration of these radiopharmaceuticals to the patient, adequate quality control should be performed. The phenomenal growth in the diagnostic use of radiopharmaceuticals has shifted much of the manufacture

Internal Quality Control

2013
Internal quality control (IQC) is a valuable technique to ensure that the results produced from any assay are reliable and reproducible. Here I describe how to set up an IQC program for a new clinical assay based on IQC samples. The principles described here are applicable to assays for any biological material.

Advances in Quality Control

1977
Publisher Summary Quality control in the clinical chemistry laboratory involves several related activities: (1) preventive measures adopted to minimize variance; (2) assessing the variance of an analytical technique by performing analyses on control material at the same time as on patients' material; (3) statistical analysis of patients' results; and

Quality Control in Cytology

1993
The matter of quality control does require two major approaches: 1 Internal quality control: this is the practice within a laboratory and demands a distinct operation under the control of a senior member of staff. 1 External quality assurance: this is usually established at an interlaboratory level and run by a professional peer ...
