Abstract: The present invention provides methods for predicting the viability of an embryo or for predicting the likelihood of a negative outcome during pregnancy by identifying the presence or absence of or determining the amount of one or more pregnancy associated markers such as molecular isoforms of hCG in a sample. In many instances, the invention is applicable to embryos generated by in vitro fertilization techniques, for instance, to embryos developing in a growth media. The present invention further provides methods for determining the amount of a pregnancy associated markers such as molecular isoforms of hCG (hCG) in a sample. The present invention also provides a diagnostic kit for predicting the viability of an embryo or for predicting the likelihood of a negative outcome during pregnancy by identifying the presence of or determining the amount of one or more pregnancy associated markers such as molecular isoforms of hCG in a sample.

Abstract: Described is a medical device and system for providing an image. The medical device may include a speculum and an imaging device. The speculum is utilized within an orifice of a patient for a surgical procedure and/or a medical examination. The speculum includes a blade which has a distal end which, in an operative position, is inserted into the orifice. The imaging device is mounted on the distal end. When the speculum is inserted into the orifice, the imaging device provides an image of an area within the orifice and surrounding tissues and structures.

Abstract: Diene modified polymers are provided as well as methods for preparing the same. The polymers have from 3-8 carbon atoms, from about 0.00005 to about 5 mole percent diene based on the total weight of the polymer. The polymers are essentially gel-free and exhibit enhanced melt strength and shear thinning behavior.
