Summary
Patulin contamination in apples is a concern. Even after removing rotten tissue, patulin (a mycotoxin) can migrate, but it was not detected 1 cm beyond the rotten area.
Area of Science:
- Food safety
- Mycology
- Agricultural science
Background:
- Patulin is a mycotoxin produced by Penicillium expansum.
- Contamination of apples with patulin poses a food safety risk.
- Understanding patulin migration is crucial for food processing and safety protocols.
Purpose of the Study:
- To investigate the migration of patulin in apples.
- To determine the extent of patulin diffusion from the inoculation site.
- To assess the effectiveness of trimming rotten tissue in removing patulin.
Main Methods:
- A patulin-producing Penicillium expansum strain was isolated from apples.
- The isolated strain was inoculated into sound apples.
- Patulin was extracted and quantified at 1 cm intervals from the inoculation point.
Main Results:
- Patulin was detected migrating from the inoculation site.
- Trimming only the visibly rotten tissue was insufficient to eliminate all patulin.
- No patulin was detected at a distance of 1 cm from the periphery of the rotten area.
Conclusions:
- Patulin can migrate beyond the visibly rotten tissue in apples.
- Simple trimming of rotten tissue may not guarantee patulin removal.
- A safety margin of at least 1 cm beyond the rotten area is recommended to ensure patulin exclusion.

8.9K
Migration is long-range, seasonal movement from one region or habitat to another. This common strategy, carried out by many different organisms around the world, is an adaptive response that typically corresponds to changes in an organism’s environment, like resource availability or climate. Migrations can involve huge groups of thousands of animals as well as single individuals traveling alone and can range from thousands of kilometers to just a few hundred meters.

6.5K
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.

Cell migration, the process by which cells move from one location to another, is essential for the proper development and viability of organisms throughout their life. When cells are not able to migrate properly to their ordained locations, various disorders may occur. For example, disruption in cell migration causes chronic inflammatory diseases such as arthritis.

3.2K
Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

01:21Chemotaxis and Direction of Cell Migration
4.4K
Cells can detect chemical cues in their environment and reorganize the cytoskeleton to migrate toward them or away from them. This directional migration, called chemotaxis, is essential during embryogenesis and development, immune response, tissue repair and regeneration, and reproduction. These chemical cues can either attract or repel the cell's movement. For example, axon development is determined by a combination of chemoattractants and chemorepellents that direct the growing axon...

01:18Role of Myosin in Cell Migration
3.2K
Myosins are multimeric motor proteins involved in various cellular processes such as migration, adhesion, and proliferation. Myosin II is the most common type in animal cells, which binds and cross-links actin filaments.
Myosin II is a hexamer comprising two heavy chains with globular heads and coiled-coil tails, two regulatory light chains, and two essential light chains. The ATPase sites on the myosin heads hydrolyze ATP, and the released phosphate generates the force for contraction....
