Hatchability of Eggs Held in Plastic Bags at Two Temperatures

Plastic Bags: Hazards and Mitigation

Failure to sterilize in plastic bags.

The ideal container for discarded cultures and other contaminated materials which require autoclaving to render them safe should be reasonably cheap, resistant to corrosion, leak-proof, and capable of allowing the passage of steam to all parts of its contents. Perhaps because of the difficulty of meeting all these requirements with the metal containers which have traditionally been used some la...

Scrambling Eggs in Plastic Bottles

This issue of PLoS Genetics contains the second of two important papers describing the high levels of meiotic failure caused by exposure of female mice to a chemical known as Bisphenol A (BPA) [1]. In the first article [2], Pat Hunt and her collaborators demonstrated high levels of meiotic failure in females exposed to BPA, suggesting that BPA exposure affects maturing oocytes. This conclusion ...

Community’s perception of utilization and disposal of plastic bags in Eastern Ethiopia

Plastics, one of the most abundant materials in the world today, are one of the main sources of pollution. People’s perception of using and disposing plastic bags is primordial as they tend to be a major part of household solid waste. This study aims to determine community’s perception of usage and disposal of plastic bags in Eastern Ethiopia. A quantitative cross-sectional study has been condu...

Improvement of hatchability of chicken eggs injected by blastoderm cells.

In our first experiment, we studied the effect of injection method of blastoderm cells (BC) into the subgerminal cavity of White Leghorn embryos on hatchability of chicken chimeras. Freshly laid eggs were injected through a hole made in the equatorial plane of the eggshell (Method A). In Method B, eggs were stored pointed end down for 5 to 7 d prior to injection, and a hole was cut in the blunt...
