Abstract: An adjustable hat is provided. The hat uses snap together back adjustment straps at the back of the hat to allow adjustment of the size of the hat. The back adjustment straps are made from an elastic material such as silicone that has a high degree of elongation without failure and a low elastic modulus. The elastic properties of the back adjustment straps allow a user to provide a desired amount of tension in the hat lower band to customize the wearing experience and make the hat more comfortable to wear.

Abstract: The invention relates to a method of synchronizing a population of somatic cells in G1 for purposes of preparing the cells for nuclear transfer or nuclear transplantation by using mechanical shake-off and selection of mitotic doublet cells. This method may further comprise cooling of the cells or other means of synchronizing the cells in G1 phase for longer periods of time. The invention also relates to the use of a synchronized population of rapidly, dividing somatic cells obtained by these methods as a source of donor nuclei or chromatin for use in nuclear transfer or nuclear transplantation.

Abstract: The present invention provides a method for parthenogenetic activation by injection and subsequent removal of a sperm into a mammalian cell, for example, an oocyte, an embryo, a blastomere, an inner cell mass cell, or a morulae cell.
