Safety Checks and Ten Rights of Medication Administration
0 Views •
2015
According to the landmark 1999 Institute of Medicine report To Err is Human: Building a Safer Health System, medication errors are a leading cause of preventable harm and death in hospitals. To mitigate these errors and enhance patient safety, nurses must consistently adhere to the Ten Rights of medication administration. These include the right patient, right medication, right dose, right time, right route, right documentation, right education, right to refuse, right assessment, and right...

Protein Folding Quality Check in the RER
0 Views •
2023
ER is the primary site for the maturation and folding of soluble and transmembrane secretory proteins. The calnexin cycle is a specific chaperone system that folds and assesses the confirmation of N-glycosylated proteins before they can exit the ER lumen. The primary players of this quality check pipeline are the lectins, ER-resident chaperones, and a glucosyl transferase enzyme. In case the calnexin system in the lumen fails to salvage a misfolded protein, it is transported to the cytoplasm...

A method for permanently bonding two silicon wafers so as to realize a uniform enclosure is described. This includes wafer preparation, cleaning, RT bonding, and annealing processes. The resulting bonded wafers (cells) have uniformity of enclosure ~1%1,2. The resulting geometry allows for measurements of confined liquids and gasses.

Size-Exclusion Chromatography with Multi-Angle Light Scattering for Protein Oligomers

2025
This video describes SEC-MALS, which leverages the abilities of size-exclusion chromatography (SEC) and multi-angle light scattering (MALS). In SEC-MALS, the SEC separates proteins or protein complexes based on their size, and the MALS detector determines the average molecular weight by measuring the intensity of the light scattered by the molecule at different angles.
FAQs
Assessment relies on more than a single sign of cleanliness. Inspectors can examine surface condition and visible residues, evaluate rinse quality, and use sampling or testing to look for biological contamination, including microbial growth. Considering these indicators together helps determine whether cleaning reached the required standard across equipment, work surfaces, and fluid pathways rather than relying on appearance alone.
Fluid pathways deserve explicit attention because residual material in these areas could affect the movement or contact of laboratory fluids. A check that includes pathways, alongside equipment and work-surface inspection, evaluates whether remaining material could compromise an experiment. This focus is especially relevant when workflows handle sensitive biological materials whose integrity depends on controlled conditions.
Rather than treating cleaning as complete when a surface looks acceptable, the check compares observed conditions and test indicators with the required standard. Surface condition, rinse quality, and microbial-growth results provide different evidence about cleaning performance. This comparison can reveal a need for maintenance or troubleshooting before contaminated equipment or pathways affect biological work and experimental reproducibility.
A practical workflow begins by identifying the equipment, work surfaces, and fluid pathways to assess. The operator then performs inspection and applies appropriate sampling or testing, using indicators such as rinse quality or microbial growth. Results are compared with the required cleanliness standard and recorded. This sequence links the cleaning procedure to an observable quality-control decision.
Use the check after cleaning steps and during routine quality control when sample integrity matters. In biological techniques, it is relevant to cell culture, molecular biology, and other workflows involving sensitive biological materials. The assessment can help prevent cross-contamination before it disrupts an experiment, while repeated checks provide information for routine maintenance and process troubleshooting.
Records should capture the inspected condition and the results of sampling or testing, including relevant observations about surfaces, rinse quality, or microbial growth. Keeping this information creates a history of whether cleaning meets the required standard. That record supports routine maintenance, helps investigate problems when results are unexpected, and strengthens quality control across repeated experiments.
