the purpose of food packaging is to preserve the quality and safety of the food it contains from the time of manufacture to the time it is used by the consumer. recently, the demand for safe and high quality foods, as well as changes in consumer preferences have led to the development of innovative and novel approaches in food packaging technology. one such development is the active food packag...

Regulation of the terminal stage of viral DNA development, DNA packaging, is poorly understood. A new phage T4 in vitro DNA packaging assay employed purified proheads, terminase (gp17 + gp16), and ATP to encapsidate DNA resistant to nuclease. Mature phage T4 DNA and linearized plasmid DNAs containing or lacking a cloned T4 gene were packaged with high (approximately 10%) efficiency. Supercoiled...

In this paper we have discussed about the possible practical approach to adopt the bioplastics in the field of Bulk Packaging. There are lot of hazardous effects of petroleum based plastic and packages on the environment. So there is a need of rethinking for the use of this kind of materials which create threat to the society and environment through different kinds of packaging. Here an effort ...

The 5' leader region of avian sarcoma-leukosis viruses (ASLVs) folds into a series of RNA secondary structures which are involved in key steps in the viral replication cycle such as reverse transcription, dimerization and packaging of genomic RNA. The O3 stem and three stem-loops (O3SLa, O3SLb and O3SLc) form the minimal packaging signal that is located downstream of the primer binding site (PB...

Due to its extreme hardness, chemical and mechanical stability, large band gap and highest thermal conductivity, poly-crystalline diamond (poly-C) is expected to be an excellent packaging material for biomedical and environmental MEMS devices. A poly-C thin film packaging technology has been developed to explore the application of this novel material on post-MEMS encapsulation packaging process...

During replication, the lengthy genome of dsDNA viruses is translocated with remarkable velocity into the limited space within the preformed procapsid. We previously found that a viral-encoded RNA (pRNA) played a key role in bacterial virus phi29 DNA translocation. Design of mutant pRNA sets containing two and three inactive mutant pRNAs, respectively, led to the conclusion that the stoichiomet...

This study derived toxicity estimates for a set of 136 chemical migrants from food packaging materials using in silico (computational) modelling and read across approaches. Where available, the predicted results for mutagenicity and carcinogenicity were compared with published experimental data. As the packaging compounds are subject to safety assessment, the migrating substances were more like...
