Abstract:
L'invention est relative à des mélanges d'agents frigorifiques. Selon l'invention, un tel mélange se compose de tout au plus 60 % de chlorodifluoroéthane (R142b), d'environ 15 % de dichlorodifluorométhane (R12) et d'environ 25 % de chlorodifluorométhane (R22), calculés respectivement en % en poids. Un tel mélange permet d'utiliser des températures de fonctionnement plus élevées qu'avec tout autre agent réfrigérant quelconque et présente une pression de condensation trés favorable.
Abstract:
A novel azeotropic mixture of the refrigerants R12, R22 and R142b in which a higher operating temperature and a lower operating pressure are attained than are attainable by any of the refrigerants of the mixture.

Abstract:
Provided are methods of screening subjects for lysosomal storage diseases, preferably glycogen storage diseases, using a tetrasaccharide as a biomarker. In a more preferred embodiment, subjects are screened for Pompe disease (i.e., glycogen storage disease type II). Also provided are neonatal screening assays. The present invention further provides methods of monitoring the clinical condition and efficacy of therapeutic treatment in affected subjects. Further provided are methods of measuring a tetrasaccharide biomarker by tandem mass spectrometry, preferably, as part of a neonatal screening assay for Pompe disease.
Abstract:
A shirt and lower undergarment are disclosed that provide a system for keeping a shirt in a tucked-in position. The shirt having strips of fabric attached to the interior on the front, back and sides with snaps on the strips of fabric. The lower undergarment disclosed may also have snaps attached using strips of fabric, with the snaps on the undergarment positioned to receive the snaps on the shirt and hold the shirt in a tucked position.
