Decontamination for Laboratory Biosafety
0 Views •
2023
Robert M. Rioux and Zhifeng Chen, Pennsylvania State University, University Park, PA Decontamination is essential for laboratory biosafety, as the accumulation of microbial contamination in the laboratory can lead to the transmission of disease. The degree of decontamination can be classified as either disinfection or sterilization. Disinfection aims to eliminate all pathogenic microorganisms, with the exception of bacterial spores on lab surfaces or equipment. Sterilization, on the other hand,...

A method to preserve, detect and sequence RNA from Avian Influenza Viruses was validated and extended using natural faecal samples from birds. This technique removes the necessity of maintaining a cool chain and handling of infectious viruses and can be applied in a 96-well high-throughput setup.

Epigenetic Regulation

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer. In most mammals, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY). The X chromosome contains significantly more genes than the Y chromosome. Therefore, to prevent an excess of X chromosome-linked gene expression in females, one of the two X chromosomes is randomly silenced during early development.

GTPases and their Regulation
0 Views •
2020
Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒ small G-proteins consisting of a single domain and large multi-domain G-proteins. Large G-proteins, also known...

Regulated Protein Degradation

2020
It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells. Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...
FAQs
Risk assessment links the biological material and planned activity to safeguards proportionate to the potential hazard. It informs choices about procedures, facility design, personal protective equipment, containment level, training, and waste handling. This matching process helps laboratories reduce exposure and accidental release without treating every experiment identically, supporting safer and more consistent biological research.
Containment levels and facility design help control hazards associated with biological work, while personal protective equipment adds protection for personnel during procedures. These elements work together rather than functioning as substitutes. The facility and containment approach establish appropriate controls for the work, while protective clothing and equipment help reduce individual exposure when biological materials are handled.
Training helps personnel apply required procedures consistently, while documentation records how biological agents are handled, stored, transported, and managed. Together, they support accountability and laboratory quality, make compliance practices easier to follow, and strengthen public confidence. They also help biosafety oversight address accidental release, cross-contamination, and potential misuse.
A practical compliance workflow begins with assessing the biological hazard and the planned work. The laboratory then aligns procedures, facility design, containment level, protective equipment, training, and waste disposal with that assessment. Requirements for storage, transport, and documentation must also be addressed. This coordinated approach turns risk information into day-to-day safeguards.
Biological agents must be considered throughout their movement and retention in the laboratory, not only during manipulation. Transport and storage requirements help control how materials are moved and kept, while documentation supports oversight of those activities. Waste disposal completes the handling process by reducing the chance that biological hazards persist after the research or diagnostic work ends.
Biosafety oversight is especially important when work involves pathogens, genetic engineering, or emerging infectious diseases. In these settings, risk assessment and containment requirements provide a framework for scientific investigation while reducing threats to people, animals, and the environment. Applying these principles to changing research contexts supports responsible innovation and helps maintain public confidence.
