- The book How & Why Animals Hatch From Eggs by Elaine Pascoe is a great book to read during this unit. It talks about a variety of animals that lay eggs and shows real photographs throughout the book. I love to focus on the different types of eggs in the book. The boys and girls are always amazed at the different colors and sizes! One really cool (but time consuming) activity that I enjoy doing with my class, is to make paper mache eggs in various sizes and colors. ...

32. Georgia's Ukrainian Easter Eggs

- UKRAINIAN EASTER EGGS.
- The art of making these eggs goes back many years. ... According to Ukrainian legend, people decorated eggs believing that great powers were embodied in the egg. To them, eggs symbolized the release of the earth from the shackles of winter and the coming of spring with its promises of new hope, new life and prosperity, and that as long as pysanky were decorated, goodness would prevail over evil throughout the world.
- Many ancient Ukrainians believed the eggs possessed magical powers and that wealth could be obtained by decorating the eggs with certain symbols. ...
- A family produced many eggs during this time to be shared with friends and family and the local priest. ...
- It seems that the women of the house were to make all these eggs during Lent. ... An interesting piece of information I found was that before they would begin to create the pysanky, they would pray "God help me" and they also prayed that the person who received the eggs would be given joy, good fortune, happiness and protection from harm.
- flowers, and other pictures and symbols are added to the eggs (to be explained later. ...
- It never ceases to amaze me that no two eggs I've made are ever totally alike. ...
- My eggs are raw and will eventually dry up. ... I was not taught to blow the eggs out, but was told that the raw egg traditionally stood for the Resurrection of Jesus Christ, so I prefer keeping it that way. I still have eggs from my mother that I made as a teenager. ...
- Eggs can take as little as hour for me or as much as 3 hours. ... I usually like to work on three eggs at a time. ... I make about 2 dozen eggs and sometimes make up to 3 dozen. ...

36. The NO Pathway Acts Late during the Fertilization Response in Sea Urchin Eggs -- Leckie et al. 278 (14): 12247 -- Journal of Biological Chemistry
- www.jbc.org
- The NO Pathway Acts Late during the Fertilization Response in Sea Urchin Eggs* .
- Both the inositol 1,4,5-trisphosphate (InsP3) and ryanodine receptor pathways contribute to the Ca2+ transient at fertilization in sea urchin eggs. ... In the present study we pursue the hypothesis that NO is a primary egg activator in sea urchin eggs and build on previous findings that an NO/cGMP/cyclic ADP-ribose (cADPR) pathway is active at fertilization in sea urchin eggs to define its role. ... This effect is mirrored by the inhibition of cGMP and cADPR signaling in sea urchin eggs at fertilization. ...
- Sea urchin eggs contain both InsP31 and ryanodine receptor channels. The microinjection of either InsP3, ryanodine, or the ryanodine receptor agonist cADPR mobilizes Ca2+ i and activates eggs (4-6). The presence of these receptors in sea urchin eggs has been demonstrated immunologically (7, 8), and a sea urchin ryanodine receptor has now been cloned (9). ...
- Chemical inhibitors of PLC, pentosan polysulfate and U73122, can abolish fertilization Ca2+ transients in sea urchin eggs (12, 17). ... In mouse eggs, diffusion of a newly characterized PLC, PLC, from sperm to egg triggers Ca2+ oscillations and embryo development (22). ...
- In sea urchins the external application of NO to intact eggs and egg homogenates generates Ca2+ transients, although this doesn't lead to egg activation (24, 25). Eggs can be activated when microinjected with an NO donor (23). Ca2+ elevation in eggs by NO has been demonstrated to require the operation of a cGMP-mediated synthesis of cADPR (24, 25), and levels of cGMP (26, 18) and cADPR (18) are known to rise at fertilization in sea urchin eggs. Kuo and coworkers (23) found that microinjection of an NO scavenger into eggs abolished the fertilization Ca2+ transient and prevented egg activation. Microinjection of recombinant nitric-oxide synthase (NOS) and calmodulin was sufficient to fully activate eggs, indicating that NOS substrates were present. The measurement of an increase in endogenous NO in fertilized eggs very soon after sperm-egg fusion using a fluorescent indicator dye supported the proposition that an NO rise might trigger the Ca2+ wave and egg activation; NO and Ca2+ were not measured simultaneously, so the precise temporal relationship between the NO rise and the Ca2+ transient could only be inferred (23). ...
- This report contributes to the debate on the relative roles of the InsP3 and ryanodine receptor pathways at fertilization in sea urchin eggs. ... We have examined the temporal relationship between NO and Ca2+ in sea urchin eggs at fertilization by simultaneously measuring these signaling components. ...
